[0035] A cylinder 36 is fixedly installed at the center of the top of the rotating disk 2. An assembly disk 37 is fixedly installed at the telescopic end of the cylinder 36. Pulling ropes 38 are fixedly installed at the other ends of the four moving rods 31 away from the center of the rotating disk 2, and one ends of the four pulling ropes 38 extend out of the working disk 22 and are fixedly connected to the assembly disk 37.

[0036] In the initial state, the telescopic end of the cylinder 36 is in the extended state. Therefore, the four springs 35 can extend, pushing the four moving rods 31. The four moving rods 31 drive the four clamping blocks 33 to close together. When welding the housing is required, the housing is sleeved over the four clamping blocks 33. Then, the cylinder 36 is started and the telescopic end of the cylinder 36 is controlled to move downward, driving the assembly disk 37 to move downward. The downward movement of the assembly disk 37 drives the four pulling ropes 38 to move downward.

When in use, starting the motor can drive the rotating disk 2 to rotate.

[0045] The device is used as follows:

[0046] In the initial state, the four clamping blocks 33 are close to each other. When the cover shell needs to be welded, the cover shell is covered on the four clamping blocks 33. Then, the cylinder 36 is started and the telescopic end of the cylinder 36 is controlled to descend, so that the assembly plate 37 drives the four pull ropes 38 to descend. The four pull ropes 38 synchronously pull the four moving rods 31 to move.
