Of course, in other embodiments, the shaft 151 may be integrated with the buckle 15. In addition, in order to make the buckle plate 15 save more labor when buckled, a lever protrusion 135 is convexly arranged on one inclined side wall of the mounting hole 131, a push rod protrusion 157 is convexly arranged in the middle of the buckle plate 15, the push rod protrusion 157 is pressed against the lever protrusion 135, and the lever principle is utilized to improve the smoothness of the rotation of the buckle plate 15, so that the buckle plate is more convenient for a user to use.

In addition, in order to make the connection between the connection member 50 and the fixing base 10 and the clamping assembly 30 more stable, both ends of the connection member 50 and both ends are connected by threads. Specifically, a threaded hole is formed in the surface of the suction cup cover 13 facing away from the suction cup 11, one end of the connecting piece 50 is a threaded shaft, and the connecting piece 50 is fixedly connected through the matching of the threaded shaft and the threaded hole. Meanwhile, the lower panel 313 in the clamping assembly 30 is fixedly connected with a locking piece, the other end of the connecting piece 50 is provided with a threaded hole, and the locking piece is screwed into the threaded hole, so that the assembly of the support frame 100 is realized, the overall structural stability of the support frame 100 can be effectively improved, and the use flexibility and safety of a user are ensured.

The above is only the optional embodiment of the present invention, and not therefore the limit of the patent scope of the present invention, all of which are in the concept of the present invention, the equivalent structure transformation of the content of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
