[0025] The pressing assembly 10 includes a positioning column 1001, the positioning column 1001 is fixedly connected in the bottom shell 1, a sliding column 1002 is slidably connected to the positioning column 1001, a second limiting block 1004 is fixedly connected to the sliding column 1002, a first spring 1003 is fixedly connected between the positioning column 1001 and the second limiting block 1004, and a second limiting nut 1005 matching the sliding column 1002 is arranged on the sealing cover 7. Under the action of the first spring 1003, the second limiting block 1004 and the second limiting nut 1005 drive the sealing cover 7 to move downward, and the sealing cover 7 is sealed with the bottom shell 1 under the action of the positioning rod 4 to avoid dislocation of the sealing cover 7 when moving.

[0026] The sealing cover 7 is provided with connection holes matching the sliding column 1002 and the positioning rod 4, and the sealing cover 7 is matched with the bottom shell 1. The sealing cover 7 is passed through the connection holes and cooperates with the second limiting nut 1005 and the first fixing nut 6 to fix the sealing cover 7.

[0027] The bottom shell 1 is provided with a sealing assembly 12, which includes a cylinder 1201. The cylinder 1201 is symmetrically provided in the bottom shell 1. A cavity 1202 is provided in the cylinder 1201. A piston 1203 is slidably connected in the cavity 1202. A moving rod 1204 is fixedly connected to the top of the piston 1203. A support block 1206 is fixedly connected to the top of the moving rod 1204. The moving rod 1204 is driven downward by the support block 1206, thereby pulling the second spring 1205 to drive the piston 1203 to move downward, and the air in the cavity 1202 is sent into the inflation ring 1208.

[0028] A second spring 1205 is connected between the support block 1206 and the top of the cylinder 1201. A connecting pipe 1207 is connected to the cylinder 1201. One end of the connecting pipe 1207 is fixedly connected to an inflatable ring 1208. The cavity 1202 is connected to the inflatable ring 1208 through the connecting pipe 1207, and air is sealed between the cavity 1202 and the inflatable ring 1208.

[0029] The bottom shell 1 has two sides with connecting ports matching the circuit, and the inflatable ring 1208 is fixedly connected in the connecting ports. The circuit enters the bottom shell 1 through the connecting ports, and the bottom shell 1 is sealed by the inflatable ring 1208 and the connecting ports cooperating with each other.

Under the action of the first spring 1003, the second limiting nut 1005 drives the sealing cover 7 to move downward, so that the sealing cover 7 and the bottom shell 1 are sealed. When the sealing cover 7 moves downward, the sealing cover 7 drives the support block 1206 to move, so that the piston 1203 moves, and the air in the cavity 1202 is sent into the inflation ring 1208, so that the inflation ring 1208 expands and is close to the line passing through the communication port, further preventing dust from entering the bottom shell 1.

[0033] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
