[0030] A winding roller 3 is bolted to the upper bottom surface of the rear end of cylinder three, and a yarn 32 for drawing lines on the ground is arranged around the winding roller 3. The yarn 32 can be recovered by rotating the winding roller 3. A dust cover 31 is hinged on the outer side of the winding roller 3 to prevent dust from accumulating on the outer side of the yarn 32. The lower end of the dust cover 31 is hinged to the outer wall of the upper end of cylinder three, and the upper end is arranged on the outer wall of the rear side of cylinder two. The dust cover 31 can be opened by pulling the upper end of the dust cover 31 backwards. A pressure roller 4 is arranged on the inner wall obliquely below the winding roller 3 at the top of the cylinder three, so that the yarn 32 on the winding roller 3 passes through the hole four and is vertically turned by the pressure roller 4 and then connected to the fixing component 5. The outer sides of cylinders two and three are connected to a frame 1, and the lower bottom surface of the frame 1 is provided with four universal wheels 12 and two limit components , four universal wheels 12 are symmetrically fixed on both sides of the bottom of the frame 1, and two are respectively provided on each side, and two limit assemblies are symmetrically fixed between the two universal wheels 12 on each side. A handrail 11 is fixed to the rear end of the frame 1. The worker pushes the cart to move by the handrail 11 and the universal wheel 12, which can save the worker's effort and facilitate movement. When in use, ink is poured into the cylinders 2 and 3 of the support cover 2 so that the yarn 32 is completely immersed in the ink, and a part of the fixing assembly 5 connected to the yarn 32 is disassembled and fixed to one end of the drawing line, and the cart is pushed back to the other end of the drawing line and fixed by the limit assembly, and the yarn 32 stained with ink exposed between the cart and the fixing assembly 5 is dragged to contact the ground to draw the line on the ground, so that the line drawing is convenient and can be drawn quickly.

[0031] The limiting assembly includes a hinge 7 and a fixing rod 8. One end of the hinge 7 is welded and fixed to the bottom of the frame 1, and the other end is welded and fixed to the fixing rod 8.

The nozzle 604 is arranged at the top of the telescopic rod 601 and connected to the upper end of the hose 603. The ink is extracted by the micro water pump 602, reaches the nozzle 604 along the hose 603, and is sprayed on the wall through the nozzle 604. The cart is pushed to make the nozzle 604 draw lines on the wall. When the line is higher than the height of the worker, the worker can directly draw the line without the help of external tools, which is convenient for use.

[0034] The telescopic rod 601 includes telescopic rod 1, telescopic rod 2 and telescopic rod 3. Telescopic rod 1, telescopic rod 2 and telescopic rod 3 are all hollow stainless steel tubes with increasing diameters. Telescopic rod set 1 is arranged above telescopic rod 2, telescopic rod 2 is arranged above telescopic rod 3, telescopic rod 3 is fixed and passes through hole 1 of cylinder 1, and the diameter of telescopic rod 3 is consistent with the diameter of hole 1. The setting height of telescopic rod 1 and telescopic rod 2 is adjusted according to the required drawing height.

[0035] Rubber rings 611 are respectively provided at the connection between telescopic rod 1 and telescopic rod 2 and at the connection between telescopic rod 2 and telescopic rod 3. The rubber rings 611 increase the friction between the telescopic rods 601 to make the connection more stable. The nozzle 604 is arranged at the top of the telescopic rod 1 and forms a telescopic structure through the telescopic rods 1 and 2.

[0036] The use process of this embodiment is as follows:

The worker holds the handrail 11 and drags the frame 1, drives the trolley to move to the other end of the drawing line through the universal wheel 12, and rotates the fixing rod 8 to be perpendicular to the ground to fix the trolley. At this time, the yarn 32 soaked with ink is located between the trolley and the connecting seat 502, and forms a straight line. The yarn 32 is dragged to make it contact with the ground, so as to form an ink line on the ground;

[0038] When drawing lines on the wall, the telescopic rod 1 and the telescopic rod 2 of the telescopic rod 601 are pulled upward until the nozzle 604 is at the height of the drawing line, and the rubber ring 611 is moved to be located at the connection between the telescopic rod 1 and the telescopic rod 2 and the telescopic rod 2 and the telescopic rod 3 to increase the friction between the telescopic rods 601, thereby fixing the nozzle 604, and rotating the fixing rod 8 to be parallel to the bottom of the frame 1, and then starting the micro-pump 602 to make the ink inside the cylinder 2 of the support cover 2 rise along the hose 603 and be sprayed onto the wall through the nozzle 604. At this time, the cart is pushed to make the nozzle 604 move horizontally, so that the spray path forms a straight line on the wall.
