This structure can prevent the limiting portion 11 from excessively sinking and affecting the appearance of the button.

[0040] See also Figure 4-6 In some embodiments, the connecting portion 21 is a hook, the limiting portion 11 is a slot body with bottom and side openings, the connecting portion 21 extends into the limiting portion 11 from the side and engages with the inner wall of the limiting portion 11, and the side opening width of the limiting portion 11 is smaller than the width of the connecting portion 21. When the locking member 2 is pulled outward relative to the push head 1, the connecting portion 21 breaks, or the side opening edge of the limiting portion 11 breaks, the push head 1 can be opened.

[0041] Further preferably, the number of the connecting parts 21 is two, the two connecting parts 21 are arranged symmetrically with each other, and a gap is provided between the two connecting parts 21 .

[0042] In addition to the two connection methods of the limiting portion 11 and the connecting portion 21 given in the drawings of the specification, the limiting portion 11 and the connecting portion 21 can also be formed in one piece.
