Referring to fig. 1-3, the present invention provides a connecting mechanism 98, wherein the connecting mechanism 98 includes a first fixing frame 30, a second fixing frame 40 and a connecting member 50. The first fixing frame 30 and the second fixing frame 40 are slidably connected to both sides of the connecting member 50, respectively.

The connecting piece 50 includes a first connecting section 51, a second connecting section 53 and a third connecting section 52 which are arranged in a straight line and connected end to end in sequence. The first connecting section 51 and the second connecting section 53 are respectively pivoted to two ends of the second connecting section 53. Specifically, the two ends of the second connecting section 53 are respectively provided with a first pivot portion 531 and a second pivot portion 532. One end of the first connecting section 51 close to the second connecting section 53 is pivotally connected to the first pivot portion 531, and one end of the third connecting section 52 close to the second connecting section 53 is pivotally connected to the second pivot portion 532. The first connecting section 51 and the third connecting section 52 can rotate relative to the second connecting section 53 to make the first connecting section 51 and the third connecting section 52 in a folded state or a flat state. Specifically, when the first connecting section 51 and the third connecting section 52 are folded in half, the first connecting section 51 and the third connecting section 52 rotate to the same side of the second connecting section 53 around the first pivoting portion 531 and the second pivoting portion 532 respectively, and the first connecting section 51 and the third connecting section 52 are disposed at two ends of the second connecting section 53 oppositely and symmetrically. When the first connecting section 51 and the third connecting section 52 are in a flat state, the first connecting section 51 and the third connecting section 52 respectively rotate around the first pivoting portion 531 and the second pivoting portion 532 to be located on the same straight line with the second connecting section 53. The rotation angle of the first connecting section 51 and the third connecting section 52 relative to the second connecting section 53 ranges from 0 to 95 °.

Referring to fig. 5 and 6, the first connecting section 51 is rod-shaped, the first connecting section 51 includes a top wall 502 and a side wall 501 enclosing the top wall 502, one side of the top wall 502 facing the first fixing frame 30 has a first limiting surface, the first limiting surface partially arches toward the first fixing frame 30 along the length direction to form an arch part 5021, a corresponding position of the first fixing frame 30 has a second limiting surface, and the first limiting surface and the second limiting surface are slidably attached to limit the first connecting section 51 to rotate relative to the first fixing frame 30. The side wall 501 includes a first side wall 5011 having an arc shape, two second side walls 5012 having a plane shape and connected to both sides of the first side wall 5011, and both ends of the top wall 502 are connected to the two second side walls 5012. The shape of the first through hole 32 is adapted to the first connection section 51. The third connecting section 52 has substantially the same structure as the first connecting section 51, and is not described in detail herein. The second connecting section 53 is provided with a positioning member 531. Specifically, the positioning member 531 is formed to protrude outward from the outer wall of the second connecting section 53. The positioning member 531 is disposed at an intermediate position of the second connection section 53. The first connecting section 51 is provided with a second positioning portion 511 and a third positioning portion 512 at intervals. In the present embodiment, two positions spaced apart on the outer wall of the first connecting section 51 are recessed inward to form the second positioning portion 511 and the third positioning portion 512, respectively. The third positioning portion 512 is closer to the second connection section 53 than the second positioning portion 511. The third connecting section 52 is provided with a fifth positioning portion 521 and a sixth positioning portion 522 at intervals. In the present embodiment, two positions spaced apart on the outer wall of the third connecting section 52 are recessed inward to form the fifth positioning portion 521 and the sixth positioning portion 522, respectively. The sixth positioning portion 522 is closer to the second connecting section 53 than the fifth positioning portion 521.

Referring to fig. 4, the first fixing frame 30 includes a first fixing plate 31, and a first protrusion 34 protruding toward the back surface of the first fixing plate 31 along the width direction of the first fixing plate 31, and a first through hole 32 is formed in the first protrusion 34. The first through hole 32 is used for receiving the connecting member 50 and providing a moving space for the sliding of the connecting member 50. The first fixing frame 30 protrudes toward the first through hole 32 along the inner wall of the first through hole 32 to form a first positioning portion 321 which is in limit fit with the second positioning portion 511 and the third positioning portion 512. The first positioning portion 321 is made of plastic.

The second fixing frame 40 includes a second fixing plate 41 and a second protrusion 44 protruding toward the back surface of the second fixing plate 41 along the width direction of the second fixing plate 41, and a second through hole 42 is formed in the second protrusion 44. The second through hole 42 is used for receiving the connecting member 50 and providing a moving space for the sliding of the connecting member 50. The second fixing frame 40 protrudes toward the second through hole 42 along the inner wall of the second through hole 42 to form a fourth positioning portion 421. The fourth positioning portion 421 is made of plastic.

When the first fixing frame 30 and the second fixing frame 40 are spliced together (please refer to fig. 1), the first positioning portion 321 of the first fixing frame 30 is in limit fit with the third positioning portion 512 of the first connecting section 51, and the fourth positioning portion 421 of the second fixing frame 40 is in limit fit with the sixth positioning portion 522 of the third connecting section 52, so that the first fixing frame 30 and the second fixing frame 40 are fixed relative to the first connecting section 51 and the third connecting section 52, respectively. Specifically, since the first positioning portion 321 and the fourth positioning portion 421 are made of plastic, the first positioning portion 321 and the fourth positioning portion 421 are released from the limit fit of the third positioning portion 512 and the sixth positioning portion 522 when in the assembled state; when the first positioning portion 321 and the fourth positioning portion 421 are not in the assembled state with the connection member 50, they are pressed by the third positioning portion 512 of the first connection segment 51 and are in the static friction state with the connection member 50.

When the first fixing frame 30 and the second fixing frame 40 can slide along the connecting element 50 in opposite directions and are separated by a predetermined distance (please refer to fig. 2), the first positioning portion 321 of the first fixing frame 30 is in limit fit with the second positioning portion 511 of the first connecting section 51, and the fourth positioning portion 421 of the second fixing frame 40 is in limit fit with the fifth positioning portion 521 of the third connecting section 53, so that the first fixing frame 30 and the second fixing frame 40 are fixed relative to the first connecting section 51 and the third connecting section 52, respectively. The first fixing frame 30 and the second fixing frame 40 can be rotated relative to the second connecting section 53, so that the first connecting section 51 and the third connecting section 52 are folded in half (see fig. 3).

When the first fixing frame 30 and the second fixing frame 40 are folded, a part of the first connecting section 51 and a part of the third connecting section 52 are respectively accommodated in the first through hole 32 and the second through hole 42. When the first fixing frame 30 and the second fixing frame 40 are in a splicing state, the first connecting section 51 and the third connecting section 52 are respectively and completely contained in the first through hole 32 and the second through hole 42, and half of the second connecting section 53 along the length direction is contained in the first through hole 32, and the other half along the length direction is contained in the second through hole 42.

The first fixing frame 30 is slidably connected to the connecting member 50 from the first connecting section 51, and the second fixing frame 40 is slidably connected to the connecting member 50 from the third connecting section 52. Specifically, the first fixing frame 30 can slide from the first connecting section 51 to the second connecting section 53, the second fixing frame 40 can slide from the third connecting section 52 to the second connecting section 53, and the stroke of the first fixing frame 30 and the stroke of the second fixing frame 40 are limited by the positioning member 531. When the first fixing frame 30 slides from the first connecting section 51 to the middle position of the second connecting section 53 and the second fixing frame 40 slides from the third connecting section 52 to the middle position of the second connecting section 53, the positioning element 531 is used to prevent the first fixing frame 30 and the second fixing frame 40 from continuing to slide in the direction of approaching each other, and at this time, the first fixing frame 30 and the second fixing frame 40 are in the state of being spliced together (see fig. 1).

When the first and second holders 30 and 40 receive a large external force and move in the directions away from each other to disengage the first positioning portion 321 of the first holder 30 from the second positioning portion 511 of the first connecting section 51 and/or disengage the fourth positioning portion 421 of the second holder 40 from the fifth positioning portion 521 of the third connecting section 53, the first and second holders 30 and 40 may be disengaged from the first and third connecting sections 51 and 52, respectively. In order to avoid this risk, the connection mechanism 98 further comprises a first blocking portion 513, a second blocking portion 523, a third blocking portion 33 and a fourth blocking portion 43. The first blocking portion 513 and the second blocking portion 523 are closer to the end portions of the first fixing frame 30 and the second fixing frame 40, which are away from each other, than the second positioning portion 511 and the fifth positioning portion 521, respectively. The first stopper 513 and the second stopper 523 are one of a protrusion and a stopper groove, and the third stopper 33 and the fourth stopper 43 are the other of a protrusion and a stopper groove. In this embodiment, two ends of the first connecting section 51 and the third connecting section 52, which are away from each other, are protruded downward to form a first blocking portion 513 and a second blocking portion 523, and corresponding positions of the first fixing frame 30 and the second fixing frame 40 are both provided with a limiting groove to form a third blocking portion 33 and a fourth blocking portion 43. When the first positioning portion 321 of the first fixing frame 30 is disengaged from the second positioning portion 511 of the first connecting segment 51 and/or the fourth positioning portion 421 of the second fixing frame 40 is disengaged from the fifth positioning portion 521 of the third connecting segment 53, the first blocking portion 513 and the second blocking portion 523 respectively cooperate with the third blocking portion 33 and the fourth blocking portion 43 to block the first fixing frame 30 and the second fixing frame 40 from being disengaged from the first connecting segment 51 and the third connecting segment 52 respectively.

Referring to fig. 7-9, the present invention further provides a splicing handwriting pad 99, including a connecting mechanism 98, a first handwriting pad 10 and a second handwriting pad 20, where the connecting mechanism 98 includes a first fixing frame 30, a second fixing frame 40 and a connecting member 50, the back surfaces of the first handwriting pad 10 and the second handwriting pad 20 are fixed to the first fixing frame 30 and the second fixing frame 40, and when the first fixing frame 30 and the second fixing frame 40 are in a splicing state, the first handwriting pad 10 and the second handwriting pad 20 are kept spliced; when the first fixing frame 30 and the second fixing frame 40 are folded in half, the front surfaces of the first writing pad 10 and the second writing pad 20 are attached to each other. In the present embodiment, the number of the connecting mechanisms 98 is two, and the two connecting mechanisms 98 are disposed at intervals between the first writing board 10 and the second writing board 20. The coupling mechanism 98 has been described above and will not be described in detail.

In the above-mentioned spliced handwriting board 99, when the first connecting section 51 and the third connecting section 52 are folded in half, the first fixing frame 30 and the second fixing frame 40 are folded in half; when the first connecting section 51 and the third connecting section 52 are in a flat state, the first fixing frame 30 and the second fixing frame 40 can slide relatively along the connecting piece 50 to be spliced together, or can slide reversely along the connecting piece 50 to be separated, so that the liquid crystal film of the spliced handwriting board 99 is prevented from being exposed to the outside, and the damage caused by collision of the liquid crystal film with the outside during transportation is avoided.
