A handle is also provided on the base 1. Initially, the propeller 4 is in an extended state to prevent the detection component from affecting the operation and placement of the equipment. The upper and lower ends of the propeller 4 are respectively connected to the lifting frame 5 and the base 1, and the motor 6 is started. The motor 6 drives the forward and reverse thread screws 7 in the lifting frame 5 to rotate, and the two groups of sliders 8 move toward each other. A connecting plate 9 wider than the slide groove is provided above the slider 8, and support plates 10 are provided on the front and rear sides of one end of the connecting plate 9.
