[0023] Among them, the surface of the push rod 10 is movably sleeved with a spring 11, the bottom end of the spring 11 is fixedly connected to the top end of the sleeve frame 9, and the top end of the spring 11 is fixedly connected to the bottom end of the clamping joint 7. When cutting the sealing gasket, the sealing gasket to be cut can be placed on the upper surface of the cutting table 1, and the position of the cutting knife 15 is adjusted in advance according to the needs. At this time, a person holds the sleeve frame 9 and pulls down the sleeve frame 9, while driving the push rod 10 to move downward, so that the end of the push rod 10 is away from the bottom end of the cross arm 6, which is convenient for sliding the clamping joint 7 in the cross arm 6, thereby realizing the adjustment of the position of the cutting knife 15. During the cutting operation, the hydraulic rod 3 is started to drive the fixed frame 4 to move downward, and then the bottom end of the cutting knife 15 is against the surface of the sealing gasket to be cut.

[0024] Among them, a groove 13 is provided on the surface of the movable cylinder 12, and a movable frame 16 is slidably engaged in the groove 13. One end of the movable frame 16 is fixedly connected to a fixed block 22, and a movable cylinder 2 18 is slidably inserted inside the fixed block 22.
