By adjusting the angle of the ladder 31, the gravity center of the ladder 31 can be moved to the right for balancing the influence caused by the movement of the movable plate 6, so that the overall structure stability is improved, and the possibility of overturning the support platform 2 is reduced.

Referring to fig. 5, in order to further fix the structure of the base 1, a boss 11 is formed at the top of the base, a groove 12 is formed at the bottom of the base, a vertical screw 13 is installed on the boss 11, the vertical screw 13 and the boss 11 are in threaded fit, the groove 12 is located under the boss 11, and the vertical screw 13 extends into the groove 12. The suction cup 14 is movably mounted in the groove 12, the top of the suction cup 14 is fixedly connected with the connecting seat 15, the rotating sheet 16 is formed at the bottom of the vertical screw rod 13, the rotating groove matched with the rotating sheet 16 is formed in the top of the connecting seat 15, and the vertical screw rod 13 is rotatably connected with the connecting seat 15 through the rotating sheet 16 and the rotating groove. The suction cup 14 and the connecting seat 15 can be driven to move along the vertical direction by rotating the vertical screw rod 13. The suction cup 14 may be used to make a connection between the suction cup 14 and the floor when the floor is slippery.

Referring to fig. 6, the base 1 is provided with mounting brackets 8 on two sides along the length direction, each mounting bracket 8 includes two vertical connecting plates 81 vertically arranged and a transverse connecting plate 82 connected between the ends of the vertical connecting plates 81, and the vertical connecting plates 81 are connected with the columns 3 and the base 1. Vertical adjusting grooves 83 are formed in the vertical connecting plates 81, and the adjusting grooves 83 extend to the tops of the vertical connecting plates 81. The connecting shaft 84 is installed at the bottom of the adjusting groove 83, the connecting shaft 84 is abutted to the inner wall of the adjusting groove 83, the length direction of the inner wall of the adjusting groove 83 is arranged along the width direction of the base 1, the connecting shaft 84 vertically moves along the adjusting groove 83, and the moving wheels 10 are installed at two ends of the connecting shaft 84. The mounting rack 8 is rotatably provided with a bidirectional screw 85, and the projection of the bidirectional screw 85 and the connecting shaft 84 in the vertical direction coincide with each other. Two threaded sleeves 86 are mounted on the bidirectional screw 85, and the threaded sleeves 86 are respectively in threaded fit with the bidirectional threads on the bidirectional screw 85. The bottom of the threaded sleeve 86 is hinged with a diagonal brace 88, and the two diagonal braces 88 are arranged in a crossed manner and hinged at the crossed position. Two movable sleeves 87 are sleeved on the connecting shaft 84, the bottoms of the inclined supporting rods 88 are hinged with the movable sleeves 87, and the rotating center lines of the hinged parts of the inclined supporting rods 88 are horizontally arranged along the length direction of the base 1.

Referring to fig. 6, the end portions of the two-way screws 85 on the same side are both connected with a worm wheel 851, a worm 9 is rotatably installed between the two installation frames 8, the length direction of the worm 9 is arranged along the length direction of the base 1, the worm wheel 851 and the worm 9 are meshed with each other, the end portions of the worm 9 are connected with a hand wheel, and the rotation of the hand wheel and the worm 9 can drive the two-way screws 85 to synchronously rotate, so that the heights of the moving wheels 10 on the two sides can be adjusted. When the bidirectional screw 85 rotates, the threaded sleeves 86 are driven to approach and separate from each other, the inclination angle of the inclined strut 88 is changed, the interval between the bidirectional screw 85 and the connecting shaft 84 is changed, and the height adjustment of the connecting shaft 84 and the moving wheel 10 is realized. When the moving wheel 10 is not needed, the moving wheel 10 can be folded upwards, so that the bottom of the base 1 is in contact with the ground, and the whole structure is more stable.

Referring to fig. 6, two mounting blocks 821 are fixed at the bottom of the transverse mounting plate, the mounting blocks 821 are oppositely arranged and respectively abutted to two vertical connecting plates 81, a mounting groove 822 is formed in the mounting blocks 821, the mounting groove 822 is horizontally arranged and corresponds to the position of the adjusting groove 83, and the bidirectional screw 85 penetrates through the mounting groove 822 to limit the vertical position of the bidirectional screw 85. The ends of the transverse connecting plate 82 and the vertical connecting plate 81 are connected by screws.

Referring to fig. 6, one side shaping that threaded sleeve 86 kept away from the support has last connecting block 861, goes up the articulated vertical support rod 89 that has on connecting block 861, and one side shaping that the support was kept away from to movable sleeve 87 has lower connecting block 871, installs the double-screw bolt on the lower connecting block 871, and double-screw bolt and lower connecting block 871 screw-thread fit, the double-screw bolt pass lower connecting block 871 and vertical support rod 89 and with vertical support rod 89 swivelling joint. The rotation center lines at the two ends of the vertical supporting rod 89 are horizontally arranged along the width direction of the base 1. When the moving wheel 10 is moved to the bottommost portion, the vertical support rod 89 is rotated to connect the bottom portion thereof with the movable sleeve 87, and the stud is used to fix the bottom portion of the vertical support rod 89. The vertical support rod 89 has a supporting effect, and the connecting shaft 84 and the two-way screw 85 are more stable in structure.

The implementation principle of the embodiment is as follows: the structure of the movable groove 23 and the movable plate 6 on the supporting platform 2 is added, the movable plate 6 can move horizontally under the driving of the driving mechanism, and the effect of extending the supporting platform 2 is realized. Left guardrail structure and a supporting bench 2 in the guardrail rotate to be connected, and after fly leaf 6 entered into the extension state, the structure of rotating left guardrail made the limiting plate 514 at its top and the holding tank 61 on fly leaf 6 cooperate, and the inner wall of limiting plate 514 and holding tank 61 is connected through the screw, has played the location effect to fly leaf 6, and the structure after fly leaf 6 extends is more stable. Adopt above-mentioned structure, the structure of brace table 2 is convenient for extend, can increase the support area of brace table 2, also can extend fly leaf 6 to the place that base 1 can not reach under the normal condition, and convenient to use operation platform is under construction.
