The roller bracket 351 is threadedly connected to the trolley body 33 and is located on the side of the trolley body 33 close to the workbench 1; the rotating roller 352 is rotatably connected to the roller bracket 351 and is located on the side of the roller bracket 351 close to the workbench 1; the thin nut 353 is threadedly connected to the roller bracket 351 and is located on the side of the roller bracket 351 close to the trolley body 33; the floating spring 354 is sleeved on the outside of the roller bracket 351 and is located between the trolley body 33 and the roller bracket 351.

[0043] In this embodiment, the guide rail 31 is installed above the column 2, and there are two of them, which are relatively distributed on both sides of the column 2. The linear bearings 32 can move on the guide rail 31, and there are multiple of them, which are relatively arranged on the guide rail 31 in pairs. The trolley body 33 is fixed above the linear bearings 32, and the linear bearings 32 are used to move to increase the rigidity and reduce the friction. The stepper motor 341 is installed above the column 2, and the output end is fixedly connected to the coupling 342, and the output end of the coupling 342 is fixedly connected to the ball screw 3431 The ball screw 3431 is driven to rotate, the rotating nut 34321 is installed on the ball screw 3431 and is arranged with a relative thread to the ball screw 3431, and moves left and right following the forward and reverse rotation of the ball screw 3431. The nut seat 34322 is fixedly connected to the rotating nut 34321 and is fixedly connected to the trolley body 33, thereby driving the trolley body 33 to move left and right; the roller support is threadedly connected to the trolley body 33, and is installed on the side of the trolley body 33 close to the workbench 1, and there are multiple roller supports, which are respectively along the trolley body 33 The rotating roller 352 is in the shape of a roller and is mounted on the roller bracket 351 through an axle rod and can rotate on the roller bracket 351.

At this time, the fixture body 51 and the test piece 8 are separated from the detection line, and the test piece 8 is replaced and re-clamped. During this period, the trolley body 33 continues to move to detect other test pieces, so that the test piece 8 can be replaced without stopping work, thereby promoting higher detection efficiency.
