[0026] In the embodiment, the telescopic unit 3 comprises a first pulley 31, a second pulley 32 and a flexible cable 33, the first pulley 31 is rotatably installed on the fixed platform 1, the second pulley 32 is rotatably installed on the second surface, the flexible cable 33 is transmissionally connected with the first pulley 31 and the second pulley 32, and one end of the flexible cable 33 is an input end. A power source can be connected with the input end of the flexible cable 33 to provide power for the operation of the test device. In use, the power source pulls the flexible cable 33 through the input end, so that the second pulley 32 is driven by the power source to approach the fixed platform 1; when the power source does not input power to the input end, the connecting part 2 is away from the fixed platform 1 under the action of the self-weight due to the connection with the transverse bearing steel cable 5.
