[0053] It should be noted that the shape of the clamping plate 501 is T-shaped. When the driving motor 503 is started to drive the threaded lead screw 502 to rotate, the clamping plate 501 is limited by the groove on the bottom plate 1 and cannot rotate. Therefore, the two clamping plates 501 will move in the same direction to clamp the top cover plate from both sides and center it. The bottom plate 1 can be fixed to the workbench surface by welding or using bolts.

[0054] Embodiment 2:

[0055] On the basis of Embodiment 1, in order to facilitate the placement of the top cover plate and the connecting piece, an opening component is arranged on the bottom plate 1. The opening component includes: a cross bar 301 fixedly connected through the pressing plate 201 for driving the pressing plate 201 to press down; a first fixing plate 302 fixedly connected above one side of the bottom plate 1; a mounting member 303 sliding on the first fixing plate 302; a first return spring 304 fixedly connected below the mounting member 303.

[0056] As a preferred implementation method, the opening component further includes: a second fixing plate 405 fixedly connected to the side of the bottom plate 1 away from the first fixing plate 302; a bearing member 401 for placing one end of the cross bar 301; a second return spring 402 fixedly connected below the bearing member 401; a limiting post 403 arranged on the card slot 404 for keeping the cross bar 301 stable; a card slot 404 arranged on the bottom side of the bottom plate 1 for clamping the limiting post 403.

[0057] As a preferred embodiment, one end of the cross bar 301 is rotatably connected to the mounting member 303, one end of the first return spring 304 is fixedly connected to the first fixing plate 302, and one end of the second return spring 402 is fixedly connected to the second fixing plate 405. The first fixing plate 302 and the second fixing plate 405 are symmetrically arranged.

[0058] It should be noted that the distance between the first fixing plate 302 and the second fixing plate 405 is greater than the length of the top cover plate. Telescopic rods for limiting are arranged in the middle of the first return spring 304 and the second return spring 402, so that the first return spring 304 and the second return spring 402 will not bend when being pressed down. The lengths and tensions of the first return spring 304 and the second return spring 402 are the same. When the limiting post 403 is located in the card slot 404, the cross bar 301 is in a horizontal state.

[0059] Embodiment 3:

The circular ring 203 slides in the circular groove 205.

[0063] It should be noted that the depth of the circular groove 205 is the same as the thickness of the circular ring 203. The buffer spring 204 is located above the pressing plate 201. When pressing down, the upward movement of the sliding rod 202 will drive the buffer spring 204 to stretch. The lengths of the cross bars 301 on both sides of the pressing plate 201 are the same, so as to ensure that the first return spring 304 and the second return spring 402 receive the same force when pressing down from the center point of the pressing plate 201.

[0064] The operation steps are as follows: The operator places the top cover plate of the washing machine and the connection part smeared with glue on the bottom plate 1, starts the driving motor 503 to drive the threaded lead screw 502 to rotate, drives the two groups of clamping plates 501 to move towards the middle at the same time, clamps and limits the top cover plate and the connecting part in the middle. Then, hold one side of the cross bar 301 close to the clamping groove 404 and drive the pressing plate 201 to rotate until the clamping groove 404 fits onto the limiting post 403.
