In this way, the pressing assembly can ensure the pressing effect and accuracy of the sponge pad.

[0035] The structure of the displacement mechanism 7 is refined as follows: Figure 4 and Figure 5The two sides of the storage groove 31 are provided with movable cavities 33, and the opposite sides of the storage groove 31 are symmetrically provided with two guide grooves 34, which are communicated with the movable cavities 33. The displacement mechanism 7 comprises an extension rod 72 slidingly arranged in the guide groove 34, and the guide groove 34 is horizontally arranged. The extension rod 72 can only slide horizontally along the inner wall of the guide groove 34.

The other end of the extension rod 72 extends into the storage groove 31 and is fixedly connected with an end plate 73. The displacement mechanism 7 further comprises a movable groove 75 arranged on the extension rod 72 and the end plate 73. A sliding rod 76 is slidingly arranged in the movable groove 75. The sliding rod 76 can only move horizontally along the inner wall of the movable groove 75. The sliding distance of the sliding rod 76 in the movable groove 75 is limited by the movable groove 75, so that the sliding rod 76 cannot be separated from the movable groove 75, thereby ensuring the stable sliding of the sliding rod 76. The side of the sliding rod 76 close to the through hole 32 is fixedly arranged on one side of the clamping plate 8. The end plate 73 and the clamping plate 8 are provided with a second spring 77 sleeved on the sliding rod 76. The second spring 77 is used to push the clamping plate 8 away from the end plate 73.
