A limiting sleeve is slidably connected inside the movable groove. The limiting sleeve is rotatably connected to the plug. Rotating the limiting sleeve makes the baffle and the movable groove keep on the same plane. Then, the plug is pulled upward. The pulling of the plug makes it easy for the limiting sleeve to disengage from the inside of the movable groove, thereby facilitating the disassembly of the bracket.

[0017] 2. In this invention, when adjusting the distance between the sliders, a first rod is fixedly connected to the surface of one slider, and a positioning plate is sleeved on the first rod to fix the position of the slider. Then, the sleeve is pushed downward, and the push rod moves downward by the push of the sleeve. The movement of the push rod pulls the second spring. A second shaft seat is fixedly connected to the bottom end of the disc, and a second locking pin is fixedly connected to the second shaft seat. The push rod moves downward to facilitate one end of the second locking pin to disengage from the slot and enter the moving slot. At this time, the first locking pin is locked inside another inclined slot, which facilitates the adjustment of the distance between the support column bodies. The support column bodies are all rotatably connected by a linkage plate to keep the support column bodies moving synchronously.

[0018] 3. In this invention, when multiple base plates need to be spliced, the base plates are first kept on the same horizontal plane. Then, the bracket is fixed to another base plate with screws. A positioning post is fixedly connected to the base plate, and an arm plate is rotatably connected to the top of the positioning post.

The rotation of the pulley causes the driven post to slide inside the through groove, which facilitates the sleeve block to pull the third spring. A docking groove is provided on the clamping plate. When the base plates are docked, the pulley will be locked inside the docking groove by the elastic force of the third spring, thus completing the docking work between multiple base plates.

[0035] Specifically, when adjusting the distance between the sliders 105, a first rod 3 is fixedly connected to the surface of one of the sliders 105. A positioning plate 301 is fitted on the first rod 3 to fix the position of the slider 105. Then, the sleeve 308 is pushed downward, which causes the push rod 307 to move downward.

A locking plate 414 is fixedly connected to the top of the bracket 412. A docking groove 415 is opened on the locking plate 414. The pulley 411 is locked inside the docking groove 415.

[0037] Specifically, when multiple base plates 1 need to be spliced ​​together, the base plates 1 are first kept on the same horizontal plane. Then, the bracket 412 is fixed to another base plate 1 with screws. A positioning post 4 is fixedly connected to the base plate 1, and an arm plate 401 is rotatably connected to the top of the positioning post 4. A mounting base 410 is fixedly connected to one end of the arm plate 401, and a pulley 411 is rotatably connected to the bottom end of the mounting base 410. By pushing the base plate 1, the pulley 411 is moved to fit against one side of the clamping plate 414, which facilitates the rotation of the pulley 411. The rotation of the pulley 411 causes the driven post 403 to slide inside the through groove 402, which facilitates the pulling of the sleeve block 404 to pull the third spring 407. A docking groove 415 is provided on the clamping plate 414. When the docking work between the base plates 1 is completed, the pulley 411 will be locked inside the docking groove 415 by the elastic force of the third spring 407, thus completing the docking work between multiple base plates 1.

[0039] When adjusting the distance between the sliders 105, a first rod 3 is fixedly connected to the surface of one of the sliders 105. A positioning plate 301 is sleeved on the first rod 3 to fix the position of the slider 105. Then, the sleeve 308 is pushed downward. The push of the sleeve 308 causes the push rod 307 to move downward. The movement of the push rod 307 pulls the second spring 315. A second bearing 316 is fixedly connected to the bottom end of the disc 314, and a second locking pin 317 is fixedly connected to the second bearing 316. The downward movement of the push rod 307 facilitates the disengagement of one end of the second locking pin 317 from the inside of the slot 320 and into the inside of the moving slot 319. At this time, the first locking pin 309 is locked inside another inclined slot 313, which facilitates the adjustment of the distance between the support column bodies 108. The support column bodies 108 are all rotatably connected by the linkage plate 112 to keep the support column bodies 108 moving synchronously.

[0040] When multiple base plates 1 need to be spliced ​​together, first, the base plates 1 are kept on the same horizontal plane. Then, the bracket 412 is fixed to another base plate 1 with screws. A positioning post 4 is fixedly connected to the base plate 1, and an arm plate 401 is rotatably connected to the top of the positioning post 4. A mounting base 410 is fixedly connected to one end of the arm plate 401, and a pulley 411 is rotatably connected to the bottom end of the mounting base 410. By pushing the base plate 1, the pulley 411 is moved to fit against one side of the clamping plate 414, which facilitates the rotation of the pulley 411. The rotation of the pulley 411 causes the driven post 403 to slide inside the through groove 402, which facilitates the pulling of the sleeve block 404 to pull the third spring 407. A docking groove 415 is provided on the clamping plate 414. When the docking work between the base plates 1 is completed, the pulley 411 will be locked inside the docking groove 415 by the elastic force of the third spring 407, thus completing the docking work between multiple base plates 1.
