When the puncture needle needle falls on the rear surface of the protective head 20410, as the first reciprocating screw rod 2041 rotates, the slider 2095 is driven to reciprocate back and forth. In the process of moving backward, the slider 2095 drives the first telescopic plate 2094 to extend.

The position of the first push plate 2049 is limited, and then at the end of the second partition plate 2087, the reset plate 2083 is moved upward under the action of the fourth spring 2084, and then under the continuous rotation of the first reciprocating screw 2041, the connecting wheel 2081 drives the reset plate 2083 to push the first push plate 2049 through the coordination of the structure, thereby driving the first push plate 2049 to reset, and then cooperates with the structure of the limiting component 209 to limit the first push plate 2049, thereby completing the work of the limiting component 209 structure.
