A supporting mechanism 5 for improving the stability of the base 1 is arranged inside the base 1. Four groups of supporting mechanisms 5 are arranged on the inner wall of the base 1 in a circular array with the pin shaft 42 as the center point. By setting up four groups of supporting mechanisms 5, the stability of the base 1 can be improved, so that the plug board 3 can stably support the shear wall. The plug board 3 is provided with an adjusting mechanism 6 that can adapt to walls of different sizes. By setting the adjusting mechanism 6, the length of the plug board 3 can be extended, so that the plug board 3 can adapt to higher shear walls, and the practicability is better.

[0035] The positioning mechanism 4 includes a worm 41, a pin 42, a slide rail 43, a handle 44, a transmission shaft 45, a worm wheel 46, a toothed disc 47, a driving gear 48, a push block 49, and a connecting shaft 410; one end of the worm 41 is rotatably connected to the inner wall of the base 1, and the other end of the worm 41 passes through the base 1 and is fixedly installed with a handle 44, the worm 41 is rotatably connected to the penetration point of the base 1, the inner wall of the base 1 is rotatably connected with the transmission shaft 45, the outer wall of the transmission shaft 45 is fixedly installed with a worm wheel 46, the worm wheel 46 is meshed with the worm 41, the worm 41 can be rotated by the handle 44, and the worm 41 rotates while cooperating with the worm wheel 46 meshed with it to drive the transmission shaft 45 to rotate, the pin 42 is rotatably connected to the inner wall of the base 1, the outer wall of the pin 42 is fixedly installed with a toothed disc 47, and the outer wall of the transmission shaft 45 is fixedly installed with a driving gear 4 8.

The bottom of the push block 49 is fixedly installed with a connecting shaft 410. The end of the connecting shaft 410 away from the push block 49 is rotatably connected to the inner wall of the toothed disc 47. When the toothed disc 47 rotates, it squeezes the connecting shaft 410, so that the connecting shaft 410 squeezes the push block 49, so that the push block 49 slides on the inner wall of the slide rail 43. At the same time, the push block 49 squeezes the slide rail 43, so that the slide rail 43 drives the plug-in board 3 to slide on the inner wall of the slide groove 2.

When the two groups of plug-in plates 3 move away from each other, the gear plate 47 will squeeze the curved arm 53, so that the curved arm 53 squeezes the slide 51. At this time, the curved arm 53 will push the slide 51 to slide out to the outside of the base 1, and the bottom of the supporting plate 52 is on the same horizontal line as the bottom of the base 1. The support plate 52 is driven by the slide 51 to move to the end away from the base 1. At this time, four groups of slides 51 are used in conjunction with four groups of support plates 52 to expand the supporting area of ​​the base 1, thereby improving the stability of the base 1.

[0037] The adjusting mechanism 6 comprises a rotating shaft 61, a pinion 62, a sub-plate 63, a protrusion 64, a bidirectional screw rod 65, a stop block 66, a slider 67, a rack 68, and a knob 69; the rotating shaft 61 is connected to the inner wall of the plug-in board 3 for rotation, the other end of the rotating shaft 61 penetrates the plug-in board 3 and is fixedly mounted with a pinion 62, and the rotating shaft 61 is rotatably connected to the penetration of the plug-in board 3, and a sub-plate 63 is fixedly mounted on the outer wall of the rotating shaft 61, and the two sets of rotating shafts 61 can drive the two sets of sub-plates 63 to move The two-way screw rod 65 is rotatably connected to the inner wall of the protrusion 64, and the two ends of the two-way screw rod 65 pass through the protrusion 64 and are fixed with limit blocks 66. The two-way screw rod 65 is rotatably connected to the penetration of the protrusion 64. The outer wall of the two-way screw rod 65 is fixedly installed with a knob 69. The two-way screw rod 65 can be rotated by the knob 69 to make the two-way screw rod 65 rotate on the inner wall of the protrusion 64. The outer wall of the two-way screw rod 65 is threadedly connected with two groups of sliders 67. The two groups of sliders 67 are mirror-imaged on the outer wall of the two-way screw rod 65 with the protrusion 64 as the central axis. The side walls of the two groups of sliders 67 are fixedly installed with racks 68. The racks 68 are meshed with the pinion 62. The two groups of racks 68 can be driven to move synchronously in opposite directions through the slider 67. At the same time, the two groups of racks 68 can be driven to move synchronously in opposite directions in cooperation with the pinion 62. The two groups of rotating shafts 61 rotate synchronously in opposite directions, and the side walls of the sliders 67 fit against the outer wall of the plug-in board 3. By rotating the bidirectional screw rod 65, the two groups of sliders 67 threadedly connected thereto can be driven to fit against the outer wall of the plug-in board 3 and move synchronously in opposite directions. There are two groups of rotating shafts 61, and the two groups of rotating shafts 61 are mirror-imaged on the inner wall of the plug-in board 3 with the protrusion 64 as the central axis. The outer walls of the two groups of rotating shafts 61 are fixedly installed with sub-plates 63, and the side walls of the sub-plates 63 fit against the side walls of the plug-in board 3.

[0038] Working principle: the worm 41 can be rotated by the handle 44. When the worm 41 rotates, the worm wheel 46 meshing with it can drive the transmission shaft 45 to rotate. When the transmission shaft 45 rotates, it will drive the driving gear 48 to rotate synchronously. When the driving gear 48 rotates, the toothed disc 47 meshing with it can drive the pin 42 to rotate. At this time, the toothed disc 47 will rotate synchronously with the pin 42. When the toothed disc 47 rotates, it will squeeze the connecting shaft 410, so that the connecting shaft 410 squeezes the push block 49, so that the push block 49 slides on the inner wall of the slide rail 43. At the same time, the push block 49 will squeeze the slide rail 43, so that the slide rail 43 drives the plug-in board 3 to slide on the inner wall of the slide groove 2, so that the two groups of mirror-image-arranged plug-in boards 3 can be synchronously moved in opposite directions on the inner wall of the slide groove 2, so that the spacing between the two groups of plug-in boards 3 can be adjusted, so that the plug-in board 3 can support shear walls of different thicknesses, so as to adapt to more shear walls of different sizes. The scope of use is not limited, the applicability is better, and it is more convenient to use.

[0039] When the two groups of plug-in boards 3 move away from each other, the toothed disc 47 will squeeze the curved arm 53, so that the curved arm 53 squeezes the slide 51. At this time, the curved arm 53 will push the slide 51 to slide out of the base 1, so that the slide 51 drives the support plate 52 to move to the end away from the base 1. At this time, four groups of slides 51 are used in conjunction with four groups of support plates 52 to expand the supporting area of ​​the base 1, thereby improving the stability of the base 1 and avoiding the base 1 from losing stability due to supporting a thicker shear wall, so that the plug-in board 3 can stably support the shear wall.

[0040] The bidirectional screw rod 65 can be rotated by the knob 69 to make the bidirectional screw rod 65 rotate on the inner wall of the protrusion 64. By rotating the bidirectional screw rod 65, the two groups of sliders 67 threadedly connected thereto can be driven to fit on the outer wall of the plug-in board 3 and move synchronously in opposite directions, and the two groups of sliders 67 can be moved away from each other. At the same time, the two groups of sliders 67 will drive the two groups of racks 68 to move synchronously. At this time, the two groups of racks 68 can cooperate with the pinion 62 to drive the two groups of rotating shafts 61 to rotate synchronously in opposite directions. At this time, the two groups of rotating shafts 61 can drive the two groups of sub-plates 63 to rotate synchronously in opposite directions until the sub-plate 63 rotates to the top of the plug-in board 3 and fits with the top of the plug-in board 3. At this time, the sub-plate 63 can be used to extend the length of the plug-in board 3, so that the plug-in board 3 can adapt to higher shear walls and has better practicality.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
