[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] according to Figures 1-4 As shown, the device includes a housing 1. Screw rods 11 are movably screwed to the four corners of the interior of the housing 1. A sliding groove 12 is provided on the top surface of the housing 1 near the screw rods 11. An arc-shaped plate 13 is installed on the top surface of the housing 1 near the screw rods 11. A mounting post 14 is installed on the top of the arc-shaped plate 13. A collar 16 is installed on the side surface of the mounting post 14 through a connecting rope 15.
