[0029] It also needs to be explained that, first, adjusting base plate 10 through second adjusting screw pair 7, then adjusting base plate 10 and adjusting plate 6 simultaneously through first adjusting screw pair 3.

[0030] Because the direction of first center axis and second center axis is different, so the utility model can drive laser radar light splitting device 14 to rotate in two different directions, thereby adjusting the angle of laser radar light splitting device 14, the utility model only needs to rotate first adjusting screw pair 3 and second adjusting screw pair 7 to realize the adjustment of the angle of laser radar light splitting device 14, simple operation, fast adjustment.

[0031] The specific connecting mode of adjusting plate 6 and adjusting support seat 1 is that adjusting plate 6 is fixedly connected with two first positioning pins 9, and the axis of first positioning pin 9 coincides with first center axis, that is, first positioning pin 9 extends along the direction of first center axis, and adjusting support seat 1 is detachably connected with two first positioning blocks 4, and first positioning pin 9 passes through first positioning block 4 correspondingly.

[0032] In order to ensure that the first positioning pin 9 can rotate smoothly, and then ensure that the adjusting plate 6 can rotate smoothly around the first center axis, a first through hole for the first positioning pin 9 to pass through is formed in the first positioning block 4, and a first bearing 5 for supporting the first positioning pin 9 is arranged in the first through hole. The first bearing 5 can adopt a ball bearing or a sliding bearing.

[0033] In order to facilitate the installation of the first positioning block 4, two first sliding grooves are formed in the adjusting support seat 1, the first sliding grooves extend along the direction of the first center axis, the first positioning block 4 is correspondingly arranged in the first sliding grooves in a sliding manner, and the first positioning block 4 can be fixedly connected with the adjusting support seat 1 through a fastening bolt. By arranging the first sliding grooves, the first positioning block 4 can be accurately positioned when the first positioning block 4 is installed, so as to avoid mispositioning of the first positioning pin 9 and the first positioning block 4, and then ensure that the first positioning pin 9 can pass through the first positioning block 4 smoothly.

[0034] The specific connection mode of the substrate 10 and the adjusting plate 6 is that the substrate 10 is fixedly connected with two second positioning pins 13, the axis lines of the second positioning pins 13 coincide with the second center axis, that is, the second positioning pins 13 extend along the direction of the second center axis, and the adjusting plate 6 is detachably connected with two second positioning blocks 11, and the second positioning pins 13 pass through the second positioning blocks 11 correspondingly.

[0035] In order to ensure that the second positioning pin 13 can rotate smoothly, and then ensure that the substrate 10 can rotate smoothly, a second through hole for the second positioning pin 13 to pass through is formed in the second positioning block 11, and a second bearing 12 for supporting the positioning pin is arranged in the second through hole. The first bearing 5 can adopt a ball bearing or a sliding bearing.
