[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] according to Figure 1-Figure 3As shown, it includes a base 1, a mounting groove 11 is opened at the middle position inside the base 1, and an annular groove 12 is opened on the inner wall of the mounting groove 11, a motor 2 is embedded and installed at a position near one side inside the base 1, and the output end of the motor 2 is transmission-connected with a driving gear 21, a placement groove is opened on the top surface of the base 1 near the motor 2, and the motor 2 is placed inside the placement groove, a mounting rod 22 is installed at the top of the driving gear 21 through a bearing, and a mounting plate 23 is installed at the top of the mounting rod 22, because the mounting rod 22 is installed with the top of the driving gear 21 through a bearing, the mounting rod 22 can rotate without rotating with the driving gear 21, a screw rod 24 is movably screwed at a position near one end of the mounting plate 23, and a magnet disk 25 is installed at the bottom end of the screw rod 24 through a bearing, the bottom surface of the magnet disk 25 is arranged to fit the top surface of the driven gear 3, and the magnet disk 25 and the driven gear 3 are adsorbed and fixed.
