Two positioning blocks 70 are provided on the front inner wall of the sealing cover 20 along the edge of the circular sealing plate 50, and a pressing protrusion 71 is provided on the positioning block 70 to press against the rear side wall of the circular sealing plate 50, and the positioning block 70, the pressing protrusion 71 and the sealing cover 20 are integrally injection molded. An extension portion 51 is provided at one end of the circular sealing plate 50 away from the positioning block 70. The extension portion 51 is parallel to the circular sealing plate 50. Specifically, the extension portion 51 is rectangular and is located at the rear side of the circular sealing plate 50. The extension portion 51 is located at the upper part of the circular sealing plate 50, and the positioning block 70 is located at the lower side of the circular sealing plate 50. A pressing boss 22 is provided on the inner wall of the sealing cover 20 to press against the rear side wall of the extension portion 51. The pressing boss 22 is provided with a guiding inclined surface for facilitating the extension portion 51 to be clamped into the front side of the pressing boss 22.

[0025] Furthermore, both sides of the extension part 51 are horizontally provided with limit bars 80 to prevent it from shaking left and right. The limit bars 80 are perpendicular to the extension part 51. The rear end of the limit bar 80 is provided with an elastic deformation part 81 and connected to the inner wall of the sealing cover 20. The limit bar 80 and the sealing cover 20 are integrally injection molded. When the circular sealing plate 50 needs to be replaced, the front end of the limit bar 80 is pushed downward to open the side of the extension part 51 so that the extension part 51 can move left / right, and then the circular sealing plate 50 is rotated to make the extension part 51 move out of the tight boss 22.
