Preferably, as shown in fig. 5, 7 and 10, the outer periphery of the first shaft portion 22 is provided with a relief slope 223 near the rear end of the second shaft portion 23, the relief slope 223 being inclined so as to be farther from the support portion 313 as approaching the second shaft portion 23; the escape slope 223 is provided so as to face the support portion 313 in the sliding direction of the slider 30. The provision of the escape slope 223 makes the supporting portion 313 not contact with the first shaft portion 22, and achieves the purpose that the slider body member 31 made of resin or plastic is not in contact with the metallized rotary member 20, greatly reducing the wear of the slider body member 31, and making the slider body member 31 durable.

Further, as shown in fig. 5 to 7, a guide bar section 316 is integrally provided on a side of the slider body member 31 facing away from the slider abutment member 32, the guide bar section 316 extends straight along the extending direction of the chute 12, the elastic member 40 is a spring 41, and the guide bar section 316 is inserted into the spring 41. The guide bar section 316 cooperates with the spring 41 to reliably expand and contract the spring 41 in the direction of extension of the slide slot 12, so that the spring force applied by the spring 41 to the slider body member 31 coincides with the direction of extension of the slide slot 12, avoiding spring force components in other directions.

Further, as shown in fig. 11 to 13, two positioning protrusions 311 are integrally provided on the outer surfaces of both sides of the slider body member 31 in the width direction of the chute 12, and four positioning protrusions 311 are provided on the outer surface of the slider body member 31 in total. The two positioning protrusions 311 on each outer surface of the slider body member 31 are juxtaposed in the extending direction of the slide groove 12, and each positioning protrusion 311 extends straight back and forth in the pressing-in direction of the rotary member 20, and the positioning protrusions 311 are also bead structures. Four positioning protruding parts 311 are arranged on the outer surface of the slide body piece 31, so that the slide 30 can be pressed into the chute 12; on the other hand, after the sliding block 30 is pressed into the sliding groove 12, the positioning protruding portion 311 is in contact fit with the groove wall of the sliding groove 12 when the sliding block 30 slides, so that the contact area between the sliding block 30 and the groove wall of the sliding groove 12 can be reduced, the smoothness of the sliding block 30 moving in the sliding groove 12 can be improved, the contact reliability between the sliding block 30 and the groove wall of the sliding groove 12 can be ensured, and meanwhile, smooth sliding and reliable sliding of the sliding block 30 in the sliding groove 12 can be realized.

Further, as shown in fig. 13 and 14, the rear end surface of each positioning protrusion 311 facing the chute 12 is an abutment end surface 317, the abutment end surface 317 is an inclined surface, and is inclined so as to be closer to the chute wall of the chute 12 as it is farther from the chute bottom of the chute 12, and the abutment end surface 317 may be formed by chamfering the rear end of the positioning protrusion 311. When the rotator 20 is not pressed into the base 10, as shown in fig. 3a, the abutment end surface 317 of the positioning protrusion 311 abuts on the support arm 13. After that, when the slider 30 is driven to be pressed into the chute 12 by the pressing-in rotating member 20, the inclined manner of the abutting end face 317 provides a certain guiding function, so that the slider 30 is more easily pressed into the chute 12, the assembly reliability is improved, and the assembly is convenient. The front end of each positioning protrusion 311 is also chamfered, so that the front end surface of each positioning protrusion 311 is inclined so as to be farther from the bottom of the chute 12 and farther from the wall of the chute 12, that is, the front end surface and the rear end surface of each positioning protrusion 311 are in a symmetrical relationship, and the slide body member 31 is conveniently taken out from the chute 12 by the inclined arrangement of the front end surface of the positioning protrusion 311, thereby facilitating the replacement of the slide body member 31.

Further, as shown in fig. 4 and 9, the chute 12 includes a first chute section 121, a second chute section 122, and a limiting step 123 formed at the junction of the first chute section 121 and the second chute section 122, the width of the first chute section 121 being greater than the width of the second chute section 122; when the slider 30 is pressed into the slide groove 12, the slider 30 is movably accommodated in the first groove section 121 and can abut against the limiting step portion 123, so that the sliding range of the slider 30 is limited, and the slider 30 can only slide in the first groove section 121.

Further, as shown in fig. 3a, 3b and 4, 8 and 9, the base 10 is integrally provided with a baffle 14 at the end of the chute 12 remote from the rotating member 20, the baffle 14 covering the end of the spring 41 remote from the slider 30, i.e., the baffle 14 is distributed on the front side of the end of the spring 41. When the rotating member 20 is pressed into the base 10, the rotating member 20 simultaneously presses the sliding block 30 into the sliding groove 12, so as to drive the spring 41 to compress, and the baffle 14 can prevent the tail end of the spring 41 from being separated forward from the sliding groove 12, thereby ensuring the assembly reliability.
