The utility model discloses an adjustable parallel line marking tool which comprises a wall body and further comprises a marking assembly which comprises a marking pen used for marking along the ground and a sliding block arranged on one side of the marking pen and used for limiting the marking pen and adjusting the distance between the marking position and the wall body. The guide assembly comprises a ruler used for marking the adjusting distance of the sliding block and a back plate arranged at one end of the ruler and used for driving the ruler to move in the extending direction of the wall. The sliding block slides along the ruler, the sliding block drives the scribing pen to move, the sliding block stops moving until the distance between the scribing pen and the wall body meets the distance between the parallel line to be scribed and the wall body, then the back plate horizontally moves along the wall body, the back plate drives the sliding block to move through the ruler, and the scribing pen stops moving. The sliding block drives the scribing pen to scribe a straight line parallel to the wall body along the ground, and therefore the effect that the scribing track is always kept parallel to the wall body is achieved.

The utility model relates to the technical field of engraving, and discloses an engraving scriber convenient for marking, which comprises a concave frame, the right side of the concave frame is in threaded connection with a screw rod, the left end of the screw rod penetrates through the concave frame and is rotatably connected with a linear module sliding table through a bearing, and the moving end of the linear module sliding table is fixedly connected with a positioning frame. By arranging the convex disc, the electric air cylinder, the driving frame, the rotating motor and the pressing disc, carving materials can be conveniently pressed, held and limited, meanwhile, the carving materials can be conveniently rotated, and by arranging the concave frame, the screw rod, the linear module sliding table, the positioning frame, the sliding plate, the positioning pipe, the marking pen, the spring and the guide assembly, the carving materials can be conveniently positioned. The marking height of the marking pen can be conveniently and vertically adjusted, meanwhile, the marking pen is buffered when being subjected to concave-convex extrusion of materials, the marking pen is prevented from being damaged, and by arranging the structure, marking use can be facilitated, so that the use requirements of customers can be met, and the carving precision is prevented from being influenced.

The utility model relates to a line drawing machine, belongs to the technical field of highway construction, and particularly relates to a highway construction line drawing machine which comprises a supporting plate, and a motor is fixedly connected to the bottom of the supporting plate. The device is moved through the rolling wheels, when the ground is cleaned, the motor can be started to drive the rotating shaft to rotate and drive the fixed column on the rotating block to rotate, and due to the arrangement of the strip-shaped block, the sliding rod can be driven to swing in a reciprocating mode, and then the brush is driven to clean the ground in a reciprocating mode. Impurities on the ground of a road are cleaned in a reciprocating swinging mode, line drawing on the ground in the later period is facilitated, then the working efficiency of construction is improved, and the problems that when an existing device is used for cleaning the impurities on the ground, the cleaning effect is not ideal, and the cleaning effect is poor are solved. The line drawing of the line drawing machine on the road surface is easily influenced, and the line drawing working efficiency is reduced.
