[0015] Preferably, a screw groove is formed in the surface of the clamping nail.

[0016] The effect achieved by the above components is that the clamping nail is more quickly inserted into the inside of the elevator under the action of the screw groove.

[0017] Preferably, a magnetic plate is fixedly connected to the bottom of the counterweight, and the magnetic plate is magnetically attracted to the upper top of the elevator.

[0018] The effect achieved by the above components is that the counterweight is fixed to the upper top of the elevator under the action of the magnetic plate.

[0019] Preferably, a cushion block is fixedly connected to the bottom of the counterweight, and the cushion block is a rubber block.

[0020] The effect achieved by the above components is that the counterweight will not directly impact on the upper top of the elevator under the action of the cushion block, avoiding the damage phenomenon, when the counterweight needs to be fixed, the counterweight will not directly impact on the upper top of the elevator under the action of the cushion block, avoiding the damage phenomenon, the counterweight is fixed to the upper top of the elevator under the action of the magnetic plate, the clamping nail is inserted into the inside of the elevator under the action of the screw groove, thereby achieving the fixing effect.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that

[0022] In this invention, by setting up a splicing device, when it is necessary to splice and assemble the counterweights, the protrusion is inserted into the interior of the rectangular groove. Under the action of the retaining ring and the ring groove, the counterweights are spliced ​​together, thereby achieving the splicing effect.
