The second movable strip 5015 is pulled by one side of the box, and finally the turning strip 5016 is pulled away in the opposite direction. Since the turning strip 5016 and the clamping strip 5021 are fixedly connected, the effect displayed at this time is that the clamping half ring 5022 is also pulled away, that is, the clamping half ring 5022 for storing the instrument relaxes the clamping effect. On the contrary, when the drawer 501 is inserted, the clamping half ring 5022 will clamp the instrument according to the reverse order of activities mentioned above. When the device needs to be moved, the telescopic rod installed in the storage frame 102 is pulled out, and the top of the installation box 301 is threaded or connected by a pin, and the toggle plate 3052 is moved upward with the instep, and the lower gear 304 rotates and drives the tooth plate 303 to move downward under the side teeth of the movable tooth side plate 305.
