[0022] The baffle 6 can be removed from the mounting platform 1, so that when the support platform body 2 is installed, the number and spacing of the sliders 5 on the surface of the linear guide 4 can be adjusted according to the overall length of the support platform body 2. By changing the number and position of the sliders 5, it is possible to adapt to support platform bodies 2 of different sizes, thereby improving the flexibility of the production line. Afterwards, the support platform body 2 is fixed to the surface of the slider 5, and then the L-shaped plate 7 is installed on the surface of the slider 5, and the connecting frame 13 is fixed to the support platform body 2, thereby completing the installation operation of the support platform body 2. Compared with complex automation equipment, this design can be installed more simply and at a lower cost. When the reduction motor 8 is started, the engagement of the gear 9 and the rack 10 can make the support platform body 2 slide on the surface of the linear guide 4 through the slider 5, and this structural combination can accurately control the position of the support platform body 2, which is convenient for precise positioning between different workstations on the production line, and the limit switch 15 can provide position signals to the external control system to help realize automation control, such as automatic stop, automatic start and other functions, thereby improving production efficiency.

[0023] Furthermore, a mounting shell 11 is detachably connected to the surface of the mounting platform 1, a tank chain 12 is slidably connected to the inner wall of the mounting shell 11, and a connecting frame 13 is fixed to one end of the tank chain 12, and the connecting frame 13 is detachably connected to the supporting platform body 2;

[0024] The tank chain 12 can protect cables and hoses. It can accommodate various wires, cables, air pipes and other flexible pipelines to prevent them from being worn, pulled or other mechanically damaged during movement. The mounting shell 11 and the mounting platform 1 are detachable, allowing users to choose whether to install the tank chain 12 according to their needs.

[0030] After the supporting platform body 2 moves to the end position of the mounting platform 1 , the buffer block 17 can contact the supporting platform body 2 and provide a buffering effect therefor, thereby preventing the supporting platform body 2 from separating from the mounting platform 1 .

[0031] Furthermore, both the gear 9 and the rack 10 are provided with helical teeth;

[0032] When helical teeth mesh, contact gradually transitions from one end of the tooth to the other, rather than instantaneous full contact like straight teeth. This reduces impact and vibration and makes the transmission smoother.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
