[0021] In this embodiment, a support mechanism 18 is fixedly installed on one side of the slider 17, one end of the support mechanism 18 is fixed inside the slide groove 9, one end of the slider 17 is fixed on the movable seat 4, the measuring assembly 6 includes a support rod 12 and a measuring scale 13, a balance seat 15 is fixed on the measuring scale 13, a metering seat 16 is fixedly installed on the balance seat 15, a displacement mechanism 14 is fixedly installed on the support rod 12, a movable column 11 is movably installed on the displacement mechanism 14, a connecting seat 10 is fixed on one end of the movable column 11, the connecting seat 10 is movably contacted with one side of the movable seat 4, the connecting seat 10 is movably installed inside the limit seat 8 and the fixed seat 1, the displacement mechanism 14 is an electric push rod, the electric push rod pushes the connecting seat 10 to enter the bottom of the limit seat 8, and provides upper and lower limit fixation for the metering seat 16.

[0022] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first fix the fixing seat 1 on the ground. After the fixing seat 1 is fixed, the measuring component 6 is installed inside the cavity 5 through the measuring scale 13 and the balancing seat 15. The measuring scale 13 and the balancing seat 15 cooperate to support the measuring seat 16. The two ends of the measuring seat 16 are limitedly supported by the limiting seat 8 to avoid the measuring seat 16 from being tilted and damaged when entering the car.
