[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0021] See also Figures 1 to 3 A laser-assisted measurement mechanism includes a support plate 1, wherein three or more support legs 2 are rotatably mounted at the bottom of the support plate 1, and the rotation of the support legs 2 is fastened by positioning bolts. The support plate 1 can be supported by the support legs 2, and the angle of the support legs 2 can also be adjusted to adjust the support height according to needs. After adjustment, the support plate 1 can be fixed in place by positioning bolts, and a laser instrument 6 is provided above the support plate 1;

[0022] The support plate 1 is rotatably connected with the adjustment plate 4, the top of the support plate 1 is fixed with a damping shaft 3, the adjustment plate 4 is fixed on the top of the damping shaft 3, the axial angle of the adjustment plate 4 and the laser instrument 15 can be adjusted through the damping shaft 3, and can be positioned after adjustment, so as to ensure the stability of the adjustment plate 4 after adjustment;

[0023] A universal shaft 7 is installed on the top of the adjustment plate 4, and a mounting plate 8 is installed on the top of the universal shaft 7. The adjustment plate 4 is threadedly connected with a plurality of bolts 5, and the plurality of bolts 5 are vertically penetrated through the adjustment plate 4. The top of the bolt 5 abuts against the bottom of the mounting plate 8, and the bottom end of the bolt 5 is the adjustment end. By rotating the bottom end of the adjustment bolt 5, the top of the bolt 5 moves up or down, and the mounting plate 8 and the laser instrument 15 can be adjusted horizontally or circumferentially in angle in cooperation with the universal shaft 7. The operation is simple and convenient, and the adjustment range is smaller; the bolts 5 on one side are adjusted downward to move the other two bolts 5 upward to adjust the circumferential angle of the mounting plate 8 and the laser instrument 6;

[0024] A guide groove 9 is provided on the mounting plate 8, and two sliders 13 are slidably connected in the guide groove 9. The mounting plate 8 is rotatably connected with a screw rod 11, and threads with opposite rotation directions are respectively provided on both sides of the screw rod 11. The screw rod 11 passes through the slider 13 and is threadedly connected with the corresponding slider 13 through two sections of threads. The clamping plate 12 is rotatably connected to the upper end of the slider 13, and one end of the screw rod 11 passes through the mounting plate 8 and is fixedly connected with a handle 10;

[0025] Place the laser instrument 6 on the mounting plate 8, and then turn the handle 10. The handle 10 drives the screw 11 to rotate. Since the two sliders 13 are respectively connected to the screw threads through threads with opposite rotation directions, the rotation of the screw 11 drives the two sliders to slide closer to or away from each other under the guidance of the guide groove 9, thereby driving the two clamping plates 12 connected to the sliders to move toward or away from each other. By moving the clamping plates 12 toward each other and approaching each other, the laser instrument 6 can be stably clamped and fixed; after use, turn the handle 10 in the opposite direction to make the two clamping plates 12 move in opposite directions and away from each other, and the laser instrument 6 can be removed. The operation is simple; when no longer in use, the clamping plates 12 can be folded and stored, thereby reducing the space occupied by the clamping plates 12 for storage and carrying.
