A second handle is fixedly provided at the input end of the second screw 109, and the two movable plates 110 are slidably connected to the inside of the rotating frame 108. By passing compressed air into the vacuum generator 103 to form a pressure difference, the air between the vacuum suction cup 102 and the testing table is drawn out so that the base 101 is stably adsorbed on the testing table. The first screw 104 is driven by the motor to rotate, thereby driving the sliding box 105 to move in the vertical direction to adjust the height. By rotating the first handle, the worm 106 is driven to rotate, thereby driving the worm gear 107 and the rotating shaft to rotate, thereby driving the rotating frame 108 to rotate and adjust the appropriate angle. The second screw 109 is driven by the second handle to rotate, thereby driving the two movable plates 110 to move, thereby adjusting the distance between the two sets of clamps 205 according to the length of the metal material.

According to the thickness of the metal material, the cylinder 206 is started to drive the bilateral rack 204 to pass through the square groove of the connecting plate 201 and move to the other side. The bilateral rack 204 drives the two meshing gears 203 to rotate. The rotation of the gear 203 drives each group of two clamping jaws 205 and the anti-slip pad to approach and clamp the metal material. After the clamping is completed, the device is placed on the inspection On the testing platform, compressed air is introduced into the vacuum generator 103 to form a pressure difference, and the air between the vacuum suction cup 102 and the testing platform is drawn out from the ventilation groove of the base 101, so that the base 101 is stably adsorbed on the testing platform. The height is adjusted according to the testing requirements, and the motor is started to drive the first screw 104 to rotate, thereby driving the sliding box 105 to move in the vertical direction on one side of the fixed plate. The sliding box 105 drives the worm gear 107 and the rotating shaft to move, thereby driving the rotating frame 108 and the clamping jaw 205 to move to the required testing position. When the angle of the metal material needs to be adjusted during the testing process, the first handle is turned to drive the worm 106 to rotate, thereby driving the worm gear 107 and the rotating shaft to rotate, and the rotating shaft drives the rotating frame 108 to rotate and adjust to the angle required for testing to continue measuring the metal material.
