The end of the movable rod 17 is elastically rotatably connected to a locking rod 18 through a torsion spring, and the end of the locking rod 18 is integrally formed with a guide block 20 and a locking block 22 for embedding in the fixing groove 21; a frame-shaped guide groove 23 is provided in the pressing block 16 and is engaged with the guide block 20; the guide groove 23 includes an inner snap-fitting portion 24 formed at the inner end of the pressing block 16, and the inner snap-fitting portion 24 is formed at the inner end of the pressing block 16. An outward guide portion 25 is formed on one side of the engaging portion 24, an outer engaging portion 26 is formed on the outer end of the outward guide portion 25, and an inward guide portion 27 connected to the inner engaging portion 24 is formed on the side of the outer engaging portion 26; the groove surface of the outer engaging portion 26 protrudes from the groove surface of the inner engaging portion 24, and the two are transitioned by an inclined surface for pushing the locking rod 18 outward; the outer groove surface of the inner end of the guide groove 23 is concave to form the inner engaging portion 24; the inner groove surface of one side of the guide groove 23 protrudes laterally into a C shape to form the outward guide portion 25, and the outer groove surface of the other side protrudes laterally into a C shape to form The inner moving guide part 27; the inner groove surface of the outer end of the guide groove 23 is concave to form the outer engaging part 26; the inner end of the outer moving guide part 25 corresponds to the concave bottom of the inner engaging part 24; the outer end of the inner moving guide part 27 corresponds to the concave bottom of the outer engaging part 26.
