The socket section is fixed, and when the first arc clamping plate 31 contacts the bellows, the control block 55 contracts into the control groove, the first contact 56 contacts the second contact 57, the battery energizes the electromagnet 51, the electromagnet 51 attracts the iron sheet 52, the iron sheet 52 drives the second motor 33 to move, so that the first gear 331 is separated from the second gear 321, the first bevel gear 332 is meshed with the second bevel gear 421, the second motor 33 drives the moving plate 12 to move, and the moving plate 12 drives the bellows The socket section moves toward the side of the socket section close to the bellows, and at the same time, the moving plate 12 drives the driving plate 26 to move, and the driving plate 26 drives the gear ring to rotate, and the first arc-shaped gear plate 23 drives the spray head 25 to rotate around the bellows to evenly apply the sealant on the socket section of the bellows. When the socket section of the bellows is applied, the connecting spring 72 pushes the L-shaped connecting rod 71 to slide along the abutting inclined surface, so that the plug rod 73 is pulled out of the plug slot, the driving plate 26 stops moving, and the moving plate 12 continues The socket section of the bellows is driven to be inserted into the socket section of the bellows. When the L-shaped separation rod 58 contacts the baffle 50, the baffle 50 pushes the L-shaped separation rod 58 to move, so that the second contact 57 and the first contact 56 are separated from each other, and the second motor 33 returns to the initial position. At this time, the second motor 33 is started to reverse, and the second motor 33 drives the two first arc-shaped clamping plates 31 to separate from the bellows. The reversal spring 45 drives the moving screw 41 to reverse, so that the moving plate 12 returns to the initial position, which is convenient for continued use next time.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
