The surface of the guide rod 551 is provided with a reset spring 554, and the block 553 is retracted to the adjustment slot 5 31, the moving bar 552 compresses the return spring 554. Under the action of the return spring 554, the user releases the adjustment ring 540 and the adjustment rod 557. The moving bar 552 can be restored to its original position under the action of the return spring 554, so that the block 553 can pop out of the perforation 532 again, which is convenient for later use. The two ends of the return spring 554 are fixedly connected to the moving bar 552 and the fixed bar 550 respectively. The upper end of the adjustment slot 531 is movably inserted with an adjustment rod 557. The upper end of the adjustment rod 557 is movably inserted into the outer side of the mounting plate 530.

When the mounting plate 530 is inserted into the interior of the mounting track 120, the insulating rubber pad 511 at one end of the buffer support block 510 fits with the surface of the ring frame 410, so that the buffer seat 500 , the buffer support block 510 and the insulating rubber pad 511 support the ring frame 410. When the mounting plate 530 is fully inserted into the interior of the mounting track 120, the blocking block 553 moves to one side of the blocking hole 121. The user loosens the adjusting ring 540, and the moving bar 552 returns to its original position under the action of the reset spring 554. The blocking block 553 passes through the through hole 532 and is inserted into the interior of the blocking hole 121, so that the mounting plate 530 is limited inside the mounting track 120, thereby facilitating the rapid assembly of the buffer seat 500, the buffer support block 510 and the insulating rubber pad 511.

The buffer seat 500, the buffer support block 510 and the insulating rubber pad 511 support the ring frame 410. When the mounting plate 530 is fully inserted into the mounting track 120, the clamping block 553 moves to one side of the clamping hole 121. The user loosens the adjustment ring 540, and the moving bar 552 returns to its original position under the action of the return spring 554. The clamping block 553 passes through the through hole 532 and is inserted into the inside of the clamping hole 121, so that the mounting plate 530 is limited inside the mounting track 120, thereby facilitating the buffer seat 500, The buffer support block 510 and the insulating rubber pad 511 are quickly assembled. When the sealing cover 200 is connected to the housing 100, the lower end of the sealing cover 200 will fit tightly with the upper end of the adjusting ring 540, so that the adjusting ring 540 will not shake up and down inside the housing 100, and the adjusting rod 557 can be pressed and limited to prevent the adjusting rod 557 from moving upward and causing adverse effects on the engagement between the clamping block 553 and the clamping hole 121.
