[0021] The hardware product to be tested is placed on the upper surface of the test bench 1 and placed between the four groups of clamping strips 11. The servo motor 14 is controlled by the corresponding controller to drive the turntable 13 to rotate in the rotating groove 12. The cylindrical slider 17 on the bottom side of the clamping strip 11 is slidably connected to the arc guide groove 15 on the surface of the turntable 13. During the rotation of the turntable 13, the slider 17 can be pushed to slide in the slide groove 16. The clamping strip 11 is slidably connected to the limit frames 18 on both sides of the slide groove 16. During the movement of the slider 17, the clamping strip 11 can be driven to move closer to or away from the hardware product. Further, the four groups of clamping strips 11 move on the upper surface of the test bench 1 to realize the clamping operation.
