[0036] Specifically, when installing the anti-collision beam, the energy absorption box 110 is placed on the mounting table 700 so that the upper surface of the mounting table 700 fits with the lower surface of the energy absorption box 110, and then the rubber block 610 is driven by the quick clamp 600 to press against the upper surface of the energy absorption box 110, so that the energy absorption box 110 can be quickly clamped.

[0037] Furthermore, the second positioning unit 200 further includes: a fixing block 220, wherein both ends of the fixing block 220 are respectively provided with a hinge portion and a threaded hole;

[0039] Specifically, the locking screw 230 is located in the middle of the first positioning block 210, the hinge portion is located at one end of the first positioning block 210, and the other end of the first positioning block 210 is used to abut against the end of the beam body 100. By rotating the locking screw 230 to drive the first positioning block 210 to abut against the end of the beam body 100, and then continuing to rotate the locking screw 230, the locking force of the first positioning block 210 can be adjusted to meet different usage requirements.

In other words, the four positioning units respectively position the four positions of the anti-collision beam, such as up, down, left, and right, making the entire positioning layout more reasonable, with higher positioning accuracy and smaller detection error.

[0043] Furthermore, both the second positioning block and the third positioning block are provided with go / no-go gauges.

[0046] Specifically, the curvatures of the first fitting surface 211 and the second fitting surface 212 are set to cater to the curvature changes at both ends of the beam body 100 so that the two fitting surfaces can fit with the end surfaces of the beam body 100 at the same time.
