Specifically, when the plurality of top plates 23 are not moving, the screw sleeve 26 is rotated, and since the screw sleeve 26 is in threaded connection with the storage bin 22, the screw sleeve 26 can move on the storage bin 22, the screw sleeve 26 can push the extrusion column 24 to horizontally slide on the storage bin 22 through the conical surface on the screw sleeve 26 and the inclined surface end part of the extrusion column 24, and the extrusion column 24 can perform extrusion locking treatment on the side walls of the top plates 23, so that the positions of the plurality of top plates 23 are fixed, and at the moment, the positioning position of the motor housing body 2 in the vertical direction is fixed.
When unlocking, only the screw sleeve 26 is required to be reversely rotated, so that the screw sleeve 26 can be downwards moved, and the extrusion column 24 can be far away from the top plate 23 due to the action of the plate spring 25, so that the top plate 23 can be randomly moved.
Preferably, as shown in fig. 7, a second support plate 27 is fixed on the bottom plate 14, a second motor 28 is arranged on the second support plate 27, a tooth column 29 is arranged at the output end of the second motor 28 in a transmission manner, and the top of the tooth column 29 is rotatably mounted on the second support plate 27;
The outer wall of the thread bush 26 is provided with teeth, and the tooth post 29 is meshed with the teeth on the thread bush 26.
Specifically, the second motor 28 can drive the threaded sleeve 26 to rotate through the teeth on the tooth post 29 and the threaded sleeve 26, so as to provide power for the threaded sleeve 26, and when the threaded sleeve 26 moves in the vertical direction, the teeth on the threaded sleeve 26 can slide relatively with the tooth post 29 and keep the engaged state all the time, so that the tooth post 29 can always provide power for the threaded sleeve 26, and the second support plate 27 mainly plays a role in supporting the second motor 28 and the tooth post 29.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
