DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. The utility model will be further described in combination with the drawings and embodiments.

[0022] As shown in the drawings, Figures 1-5 A road surface cutting auxiliary positioner is installed on the front side of a road surface cutting machine, comprising a mounting plate 11, a support pipe 3 is rotatably connected to the mounting plate, two groups of green light one-line laser module are arranged on the support pipe, the green light one-line laser module can be purchased from Dongguan Zhiling Intelligent Technology Co., Ltd., and a 10mw 520nm laser module is needed with a drive board, and the cost of the two groups is about 35 yuan.

[0023] A positioning plate 21 is arranged on the mounting plate, a supporting plate 22 is arranged on the top of the positioning plate, a fixing hole is arranged on the support pipe, and a positioning screw 23 is threadedly connected in the positioning threaded hole on the supporting plate after passing through the fixing hole of the support pipe.

[0024] When the road surface cutting auxiliary positioner is installed and debugged, it can be put into use in road surface cutting operation. The main function of the positioner is to emit clear green light one-line by two groups of green light one-line laser modules. In the road surface cutting operation site, the operator starts the laser module, and the green light one-line is accurately projected on the road surface to form an obvious positioning mark. The two green light one-line can provide accurate cutting reference line for the operator, help the operator more accurately control the cutting direction and position of the road surface cutting machine, improve the cutting precision and quality, reduce the material waste and engineering rework caused by cutting deviation, and thus improve the efficiency and effect of road surface cutting operation.
