[0026] The extrusion detection protection mechanism 4 includes a fixed plate 401 and a fixed ring 406. The fixed plate 401 is fixedly installed on the bottom end of the piston rod of the hydraulic cylinder 3. A ring cover 402 is fixedly installed on the bottom end of the fixed plate 401. A ring sleeve 403 is fixedly installed on the top of the bottom plate 1. A pressure sensor 404 is fixedly installed on the bottom end of the fixed plate 401. A test pressure head 405 is fixedly installed on the bottom end of the pressure sensor 404. A limit rod 407 is fixedly installed on the top of the fixed ring 406.

One end of the spring 408 is fixedly installed on the top end of the fixed ring 406, and the other end of the spring 408 is fixedly installed on the bottom end of the fixed plate 401.
[0027] Specifically, the above technical solution is as follows: the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 drives the fixed plate 401 to move downward. The fixed plate 401 drives the test pressure head 405 to move downward through the pressure sensor 404. The fixed plate 401 also drives the ring cover 402 to move downward, so that the ring cover 402 is inserted into the ring sleeve 403.
