The elastic hook comprises an elastic ring sleeved on the outer peripheral wall of the telescopic rod 130 and a hanging ring connected to the bottom end of the elastic ring. Particularly, the elastic ring and the hanging ring are arranged in a circular ring structure. The elastic ring and the hanging ring can be arranged in the same plane or respectively arranged in planes perpendicular to each other. So set up, elasticity couple and telescopic link 130 ability quick assembly disassembly to can in close connection between elasticity couple and the telescopic link 130, guarantee that elasticity couple can not influenced by wind-force and remove.

The following describes a specific operation of the present embodiment:

when the swing arm 120 is at the lowest position and in the retracted state, the fork 170 is located at the left side of the second pillar 152, and the second end of the fork 170 faces the left side. At this time, the right end of the set tooth 172 engages the ratchet 150. The swing arm 120 can only rotate around the connection post 160 in the clockwise direction, and when the user pushes the swing arm 120 to rotate to a proper position, the swing arm 120 can be automatically locked. When the swing arm 120 needs to be retracted, the user pushes the swing arm 120 to swing to the highest point in the clockwise direction, the shift fork 170 contacts with the first pin 151, and the first pin 151 pushes the shift fork 170 to rotate to the left. The shift fork 170 in turn drives the shift teeth 172 to rotate to the right, thereby engaging the right end of the shift teeth 172 (here, the right end when the shift teeth 172 are at the highest point) with the ratchet 150. The swing arm 120 can rotate around the ratchet 150 in the counterclockwise direction, and when the swing arm 120 swings to the lowest point in the counterclockwise direction, the shift fork 170 contacts the second catch 152, and the second catch 152 pushes the shift fork 170 to rotate to the left. The fork 170 drives the teeth 172 to rotate to the right, so that the right ends of the teeth 172 engage with the ratchet teeth, and the device is in a stowed state.

Example 2

As shown in fig. 13 to 14, the present embodiment is similar to the structure principle of embodiment 1, and is different from embodiment 1 in that a baffle 280 is covered on an end surface of the ratchet 250 passing through one end of the swing arm 220, and the baffle 280 is respectively provided with a first through hole for passing the first stop column 251 and a second through hole for passing the second stop column, so as to fixedly connect the baffle 280 and the ratchet 250. An upper baffle piece 281 and a lower baffle piece 282 are arranged on the rear end surface of the baffle 280, and the included angle between the upper baffle piece 281 and the lower baffle piece 282 is smaller than 360 degrees. Preferably, the upper and lower blocking pieces 281 and 282 are respectively located at the top and bottom ends of the blocking plate 280, so that the maximum swingable angle of the swing arm 220 is less than 360 °. The upper blocking piece 281 and the lower blocking piece 282 are both located between the baffle 280 and the front end face of the swing arm 220.

In this embodiment, a fork 270 is disposed at an end of the mounting shaft 271 penetrating through the swing arm 220, and the fork 270 has a first end connected to the mounting shaft 271 and a second end movably abutting against the upper stop piece 281 or the lower stop piece 282. The second end is movably abutted against one side of the upper baffle 281 or the lower baffle 282 close to the swing range of the swing arm 220, and the second end is always positioned in the swing range of the swing arm 220. In particular, the upper and lower ends of the baffle 280 are close to the outer end of the fork 270, so as to ensure that the upper and lower retaining pieces 281 and 282 can act on the fork 270.

The operation of the present embodiment is the same as that of embodiment 1, except that when the swing arm 220 rotates to the highest point, the shift fork 270 is acted by the upper stop piece 281 to rotate to the left, and when the swing arm 220 rotates to the lowest point, the shift fork 270 is acted by the lower stop piece 282 to rotate to the left.

Example 3

As shown in fig. 15 to 17, the present embodiment is similar to the structure principle of embodiment 1, and is different from embodiment 1 in that the engaging members are a left set tooth 372 and a right set tooth 374 which are arranged in the lower groove 322 in a left-right symmetry manner. The upper end surfaces of the left shifting tooth 372 and the right shifting tooth 374 are both provided with ratchet teeth which can be meshed with the ratchet wheel 350 arranged in the upper groove 321. A pressing piece 375 capable of rotating left and right in the lower groove 322 is arranged between the left shifting tooth 372 and the right shifting tooth 374, and the pressing piece 375 is arranged in a fan-shaped structure. The lower part of the pressing piece 375 rotates, and the upper part of the pressing piece movably abuts against the left shifting tooth 372 or the right shifting tooth 374, so that the left shifting tooth 372 or the right shifting tooth 374 is controlled to rotate outwards.

Specifically, the bottom ends of the left pulling tooth 372 and the right pulling tooth 374 are provided with winding posts, the bottom end of the lower groove 322 is provided with a winding groove for accommodating the winding posts, and the winding posts can rotate left and right in the winding grooves, so that the left pulling tooth 372 and the right pulling tooth 374 can rotate left and right in the lower groove 322. One sides of the left shifting tooth 372 and the right shifting tooth 374 close to the inner peripheral wall of the lower groove 322 are both provided with a compression spring 373 connected with the inner peripheral wall of the lower groove 322, and the reset action of the compression spring 373 can drive the left shifting tooth 372 and the right shifting tooth 374 to rotate inwards so as to drive the left shifting tooth 372 and the right shifting tooth 374 to be meshed with the ratchet wheel 350.

With such an arrangement, since the pressing member 375 is arranged in a fan-shaped structure, when the pressing member 375 rotates rightward, the oblique edge of the right side of the pressing member 375 abuts against the straight edge of the left side of the right shifting tooth 374, and the left side of the bottom of the pressing member 375 abuts against the right side of the left shifting tooth 372, so that the left shifting tooth 372 is away from the ratchet wheel 350. At the same time, the compression spring 373 at the right set-tooth 374 is reset to drive the right set-tooth 374 into engagement with the ratchet 350. The right set tooth 374 is capable of rotating in a clockwise direction and the ratchet wheel 350 urges the right set tooth 374 to deflect to the right when rotated. After the right shifting tooth 374 deflects rightwards, the compression spring 373 on the right side is compressed, and the reset action of the compression spring 373 pushes the right shifting tooth 374 to deflect leftwards, so that the right shifting tooth 374 is continuously meshed with the ratchet wheel 350, and the right shifting tooth 374 is ensured to rotate only in the clockwise direction.

When the pressing member 375 rotates leftward, the operation principle is opposite to that when the pressing member 375 rotates rightward.

As shown in fig. 14 to 16, in the present embodiment, a front end surface of the ratchet 350 is provided with a stop column, the stop column includes a first stop column 351 and a second stop column 352, and an included angle between the first stop column 351 and the second stop column 352 is smaller than 360 °. Preferably, the first blocking pillar 351 and the second blocking pillar 352 are respectively located at the uppermost end and the lowermost end of the front end surface of the connecting plate. The front end of the pressing piece 375 is provided with a rotating column 371, the front end of the rotating column 371 passes through the swing arm 320, and one end of the rotating column 371 passing through the swing arm 320 is provided with a shifting fork 370. The shift fork 370 can be rotated left and right to drive the pressing member 375 to rotate through the rotation post 371. The shifting fork 370 is disposed in a peach-shaped configuration with a smooth outer contour, and has a first end connected to the rotating post 371 and a second end movably abutted against the first retaining post 351 or the second retaining post 352. The second end is movably abutted against one side of the first stop column 351 or the second stop column 352 close to the swing range of the swing arm 320, and the second end is always located in the swing range of the swing arm 320. When the shift fork 370 is rotated to contact the first block pin 351, the first block pin 351 pushes the shift fork 370 to rotate leftward. When the fork 370 is rotated downward to contact the second gear post 352, the second gear post 352 pushes the fork 370 to rotate leftward.

The following describes a specific operation of the present embodiment:

when the swing arm 320 is at the lowest position in the retracted state, the fork 370 is located at the left side of the second post 352, and the second end of the fork 370 faces the left side. At this point, the right set tooth 374 engages the ratchet 350. The swing arm 320 can only rotate around the ratchet wheel 350 in the clockwise direction, and when a user pushes the swing arm 320 to rotate to a proper position, the swing arm 320 can be automatically locked. When the swing arm 320 needs to be retracted, a user pushes the swing arm 320 to swing to the highest point in the clockwise direction, the shifting fork 370 contacts with the first catch 351, and the first catch 351 pushes the shifting fork 370 to rotate to the left. The fork 370 in turn drives the press 375 to rotate left, thereby moving the right set of teeth 374 away from the ratchet wheel 350, and the return spring drives the left set of teeth 372 into engagement with the ratchet wheel 350. The swing arm 320 can rotate around the ratchet 350 in the counterclockwise direction, when the swing arm 320 swings to the lowest point in the counterclockwise direction, the shift fork 370 contacts the second blocking post 352, and the second blocking post 352 pushes the shift fork 370 to rotate to the left. The fork 370 drives the left set tooth 372 away from the ratchet 350 and the return spring drives the right set tooth 374 into engagement with the ratchet, the device being in a stowed condition.

Except for the above structure, the present embodiment and the embodiment have the same structural principle.
