The limit sleeve 3 is symmetrically provided with limit sliding frames 5 that are slidably matched with it. The limit sliding frames 5 are provided with installation grooves 6. A first elastic member 7 is arranged in the installation groove 6. The two ends of the first elastic member 7 are respectively connected to the plug structure 1 and the limit sliding frame 5. One end of the limit sliding frame 5 is provided with a fixed arm claw 9. The fixed arm claw 9 cooperates with a positioning claw 15 arranged on the socket structure 2. The other end of the limit sliding frame 5 cooperates with the control structure.

[0020] In a preferred embodiment, a guiding inclined surface 8 is provided at one end of the limiting sliding frame 5 close to the control structure. It automatically cooperates and opens during the downward pressing of the extrusion head 10, which is convenient and practical.
