Each end face of the multiple reinforcing plates 13 is provided with a slot 14. A retaining ring 21 is fixedly connected to the side opposite to the boss of the sealing element 2, and the retaining ring 21 is engaged with the slot 14. This makes it easy for the sealing element 2 to be engaged with the inside of the slot 14 when it is installed, thereby achieving a firm connection between the sealing element 2 and the back cover body 1. At the same time, the use of multiple reinforcing plates 13 can increase the overall strength of the back cover body 1.

[0030] Multiple retaining plates 22 are evenly fixedly connected to the outer circumference of the retaining ring 21, and the multiple retaining plates 22 are fixedly connected to the inner wall of the sealing element 2, so that the retaining ring 21 can be firmly installed and fixed by the multiple retaining plates 22, so that it can be stably engaged and connected to the back cover body 1.

[0031] A plug-in post 23 is fixedly connected to the center of the seal 2. At the same time, multiple limiting rings 24 are arranged around the outer wall of the plug-in post 23.
