Meanwhile, when the push button 20 is pressed, the push button 20 can be changed from the locked state to the unlocked state. At this time, the button 20 is withdrawn from the predetermined path of the engaging portion 32, and is disengaged from the engaging portion 32, so that the engaging portion 32 can be taken out of the accommodating chamber 11, and the cord holder 30 can be detached. Further, it is possible to facilitate not only the installation of the tether 50 but also the detachment of the tether clip 30.

In some embodiments of the present application, the button 20 may be provided with a through hole 21 for passing the engaging portion 32, and a protrusion 22 protruding from a hole wall of the through hole 21, the engaging portion 32 includes a first surface 321 and a second surface 322 which are oppositely arranged, and the first surface 321 and/or the second surface 322 is provided with an engaging groove 323. When the button 20 is in the locked state, the protruding portion 22 is engaged with the engaging groove 323; when the push button 20 is in the open state, the protruding portion 22 is separated from the engaging groove 323.

By providing the through hole 21 and the protruding portion 22 on the button 20, the engaging portion 32 can be engaged with the protruding portion 22 when passing through the through hole 21. The engagement form may be a groove and protrusion form, that is, the first surface 321 or the second surface 322 of the engaging portion 32 is provided with an engaging groove 323, and the protruding portion 22 can be snapped into the engaging groove 323 to complete the engagement. Or the first surface 321 and the second surface 322 of the engaging portion 32 are both provided with engaging grooves 323, and the protruding portion 22 can be snapped into one of the engaging grooves 323 to complete the engagement. The engagement grooves 323 formed on the first surface 321 and the second surface 322 of the engagement portion 32 can prevent the user from confirming the engagement direction in advance when the user engages the engagement portion 32 of the lanyard buckle 30 into the accommodation chamber 11. That is, fool-proofing can be achieved by providing the engaging groove 323 on both the first surface 321 and the second surface 322 of the engaging portion 32.

In addition, in order to facilitate the engagement of the engaging portion 32 of the lanyard buckle 30 into the receiving cavity 11, a guide structure may be provided at an edge of the engaging portion 32. Such a guide structure may be a ramp or an arcuate surface. In some embodiments, the engaging portion 32 further includes a third surface 324 connecting the first surface 321 and the second surface 322 and facing away from the first opening 12, and a junction of the third surface 324 and the first surface 321 and/or a junction of the third surface 324 and the second surface 322 is provided with a chamfer (indicated by a reference sign a in fig. 3).

Or, chamfers are provided at the connection between the third surface 324 and the first surface 321 and at the connection between the third surface 324 and the second surface 322, so as to form inclined surfaces with guiding function at two opposite edges of the engaging portion 32, thereby realizing fool-proofing. Therefore, when the clamping part 32 of the rope hanging buckle 30 is clamped into the accommodating cavity 11, the resistance force when the clamping part 32 is matched with the convex part 22 of the button 20 can be reduced through the guiding action at the chamfer. So that the engagement between the catching portion 32 and the projection 22 of the button 20 is smoothly accomplished.

In addition, a guide structure may be provided at the edge of the projection 22 of the button 20. I.e. at the edge of the projection 22, a bevel or an arc-shaped surface is formed which has a guiding effect. In some embodiments, it is also possible to form the ramp with a guiding effect by providing a chamfer at the corner of the projection 22. Namely, the protruding portion 22 includes a first side 221 facing the first opening 12 and a second side 222 facing the groove, the first side 221 is connected to the second side 222, and a junction between the first side 221 and the second side 222 is provided with a chamfer (corresponding to the structure shown by reference sign a in fig. 3).

In this way, by providing the chamfer having the guiding function at the edge of the protruding portion 22 close to the first opening 12, the clamping portion 32 of the rope hanging buckle 30 is more favorably clamped into the accommodating cavity 11, and the matching between the protruding portion 22 of the button 20 and the hook is completed.

In some embodiments of the present application, in order to avoid the button 20 from being easily detached from the accommodating chamber 11, the sidewall of the accommodating chamber 11 may be provided with a stepped structure. That is, at least two step surfaces may be formed at the side wall of the receiving chamber 11, and the push button 20 may be moved on a portion of the step surfaces. As shown in fig. 2, the accommodating cavity 11 includes a side wall surface 111 surrounding the button 20, the housing 10 is further provided with a limiting portion 112 protruding from the side wall surface 111, the button 20 includes a main body portion 201, and an abutting portion 202 provided on the main body portion 201, the abutting portion 202 is slidable on the side wall surface 111 and is limited in the accommodating cavity 11 by the limiting portion 112.

The limiting portion 112 provided on the housing 10 is located on a part of the inner wall surface of the accommodating chamber 11, so that a stepped structure is formed on the side wall of the accommodating chamber 11. That is, the inner wall surface having the limiting portion 112 can cooperate with the protruding structure on the button 20 by the resisting action of the limiting portion 112 to limit the button 20 in the accommodating cavity 11. The protrusion of the button 20 is an abutting portion 202 provided on the main body 201 of the button 20, and the abutting portion 202 can slide on the sidewall 111. The main body 201 of the button 20, i.e., the main portion of the button 20, the through hole 21 and the protrusion 22 may be disposed on the main body 201.

During the sliding of the abutting portion 202, the limiting portion 112 may limit the range of the sliding of the abutting portion 202 to limit the button 20 within the accommodating chamber 11. When the abutting portion 202 slides to a position close to the stopper portion 112, the push button 20 enters the locked state, that is, the protruding portion 22 of the push button 20 and the engaging groove 323 of the engaging portion 32 enter the engaged state. When the abutting portion 202 slides in a direction away from the stopper portion 112, the protruding portion 22 of the push button 20 gradually retreats from the engaging groove 323 of the engaging portion 32, and finally retreats from the engaging groove 323 of the engaging portion 32, so that the engaging portion 32 can be taken out of the accommodating chamber 11.

In addition, in order to facilitate the installation of the push button 20, i.e. to facilitate the snapping of the push button 20 into the housing cavity 11, the abutment 202 may be made of plastic material.
