The width of the cross section of the second position-limiting portion is greater than the width of the cross section of the second sliding groove 120, so that the second position-limiting portion is reliably limited in the second position-limiting groove 140.

Further, the second slider body 232 and the two second boss portions 234 are integrally formed, so that the cross section of the second slider 230 is i-shaped, the second slider body 232 and the two second boss portions 234 are firmly connected, and the structure of the second slider 230 is compact. It is understood that in other embodiments, the second slider body 232 and the two second boss portions 234 are not limited to being integrally formed. In one embodiment, the second slider body 232 and the two second boss portions 234 are formed separately, and the second slider body 232 is welded or glued to the two second boss portions 234, respectively, so that the second slider body 232 is firmly connected to the two second boss portions 234, respectively.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
