The device is used for testing the fastening performance of a bolt and comprises a positioning clamp, a handle piece and a control panel; the positioning clamp is a cylindrical part, a limiting groove is formed in one side of the positioning clamp, a nut of the bolt can be sleeved with the limiting groove, and an adsorption part is further arranged at the bottom of the limiting groove and used for adsorbing the bolt; the handle piece is connected with one end of the multi-stage telescopic rod, and the end, away from the handle piece, of the multi-stage telescopic rod is rotationally connected with the side, without the limiting groove, of the positioning clamp through a universal joint; the control panel is installed on the handle piece and can control the multi-stage telescopic rod to stretch out and draw back, and the positioning clamp can rotate along the axis of the positioning clamp and can rotate relative to the multi-stage telescopic rod. According to the device, through the structural design that the position and the angle of the positioning fixture are adjustable, the detection of the fastening performance of the bolt can be accurately completed, and the detection efficiency is improved while the detection safety is ensured.
