[0024] An insertion rod 10 is inserted into the upper surface of the base 1 , and a stopper 11 is fixedly mounted on the top of the insertion rod 10 .

[0025] After that, the nut 9 is loosened, and the nut 9 then removes the limit on the anti-slip washer 8, thereby pulling the stopper 11, so that the bottom of the plug rod 10 on the stopper 11 is separated from the top of the slider 3, and then the mounting plate 5 can be moved, and the slide bar 4 on the mounting plate 5 drives the slider 3 to move, so as to facilitate the position adjustment of the two sets of mounting plates 5, and their positions can be adjusted according to the installation position. When adjusted to the appropriate position, tighten the nut 9 so that the nut 9 squeezes the anti-slip washer 8, so as to facilitate the positioning operation of the slider 3 on the screw rod 7 and facilitate its installation operation.

[0026] The bottom of the insertion rod 10 passes through the top of the base 1 and extends to the inside of the cavity to be plugged into the top of the slider 3.

The top of the return spring 12 is fixedly connected to the bottom of the block 11, and the upper surface of the base 1 is fixedly connected to the bottom of the return spring 12.

[0027] Pull the stopper 11 to separate the rod 10 on the stopper 11 from the stopper 11, so as to facilitate the cancellation of the limiting operation on the slider 3. When the slider 3 moves to the position separated from the rod 10, it can be initially fixed by inserting a positioning pin into the base 1. When the stopper 11 is loosened later, the rod 10 on the stopper 11 is reset, and then the reset spring 12 resets the rod 10 on the stopper 11, so that the rod 10 is inserted, so as to prevent the subsequent slider 3 from moving too much on the base 1 and prevent the slider 3 from shifting inside the cavity, which is convenient for subsequent use by staff.

[0029] The arrangement of the oblong hole achieves the effect of facilitating subsequent positioning thereof and fine-tuning of its fixed position. The arrangement of the steel ball 13 achieves the effect of facilitating supporting the base 1, thereby facilitating subsequent use.

[0030] A rod groove for the sliding rod 4 to pass through is formed at the bottom of the base 1 , and the inner wall of the rod groove is slidably connected to the surface of the sliding rod 4 .

[0031] The arrangement of the rod groove achieves the effect of facilitating the limiting of the slide rod 4, thereby facilitating the positioning thereof during subsequent use, thereby also facilitating the operation of subsequent staff.

[0032] One side of the anti-skid washer 8 contacts one side of the nut 9, and a wrench is fixedly mounted on the side of the nut 9 away from the anti-skid washer 8, and the surface of the wrench is provided with anti-skid patterns.

A limit baffle 14 is fixedly installed on one side of the anti-slip gasket 8. The limit baffle 14 is located inside the through slot, and the surface of the limit baffle 14 is slidably connected to the inner wall of the through slot.

[0035] The setting of the limit baffle 14 achieves the effect of preventing the subsequent anti-skid gasket 8 from rotating, thereby facilitating the subsequent positioning and installation operations thereof, and also facilitating the use of subsequent staff.

[0036] The upper surface of the slider 3 is provided with an insertion hole for the insertion rod 10 to be inserted, and the base 1 is provided with an insertion hole for the insertion rod 10 to pass through, and the insertion hole is communicated with the cavity.

[0039] During the use of the installed mounting plates 5, the positions of the two mounting plates 5 on the same side can be adjusted simultaneously, so as to facilitate the subsequent installation and adjustment and operation by subsequent staff.

[0040] During operation, the nut 9 is loosened, and then the nut 9 cancels the limit on the anti-slip washer 8, thereby pulling the stopper 11, so that the bottom of the plug rod 10 on the stopper 11 is separated from the top of the slider 3, and then the mounting plate 5 can be moved, and the slide bar 4 on the mounting plate 5 drives the slider 3 to move, so as to facilitate the position adjustment of the two sets of mounting plates 5, and their positions can be adjusted according to the installation position. When adjusted to the appropriate position, the nut 9 is tightened so that the nut 9 squeezes the anti-slip washer 8, so as to facilitate the positioning operation of the slider 3 on the screw rod 7 and facilitate its installation operation.

[0041] At the same time, the stopper 11 is pulled to separate the plug rod 10 on the stopper 11 from it, so as to facilitate the cancellation of the limiting operation on the slider 3. When the slider 3 moves to a position separated from the plug rod 10, it can be initially fixed by inserting a positioning pin into the base 1. When the stopper 11 is loosened later, the plug rod 10 on the stopper 11 is reset, and then the reset spring 12 resets the plug rod 10 on the stopper 11, so that the plug rod 10 is inserted, so as to prevent the subsequent slider 3 from moving too much on the base 1 and prevent the slider 3 from shifting inside the cavity, which is convenient for subsequent use by staff.
