[0021] Reference Figure 3The belt drive assembly includes a first pulley 9 and a second pulley 11. A drive belt 10 is connected between the first pulley 9 and the second pulley 11. The first pulley 9 is fixedly installed on the outside of one of the wheels 1. When the rotating shaft 2 rotates, it drives the first pulley 9 on one side to rotate. The first pulley 9 drives the second pulley 11 to rotate through the drive belt 10.

[0022] Reference Figure 3 The material conveying assembly includes a shaft 12, which is fixedly installed on one side of the second pulley 11. A material conveying cylinder 23 is fixedly installed at one end of the shaft 12. Multiple material conveying grooves 13 are opened at one end of the material conveying cylinder 23. A rotating sleeve 14 is rotatably installed on the outer side of the material conveying cylinder 23. Through grooves 15 are opened on both sides of the middle part of the rotating sleeve 14. The shaft 12 is rotatably installed in the middle of one of the second mounting blocks 8. The rotating sleeve 14 is fixedly installed between two second mounting blocks 8. The second pulley 11 rotates. The shaft 12 rotates, causing the material conveying cylinder 23 at one end to rotate along the inside of the rotating sleeve 14. The outer side of the material conveying cylinder 23 is completely aligned with the inner wall of the rotating sleeve 14 to prevent putty from leaking out. The through groove 15 of the rotating sleeve 14 corresponds to the material conveying trough 13 of the material conveying cylinder 23. The putty powder in the feed bin 22 enters the inside of the material conveying trough 13 through the upper through groove 15. When the material conveying cylinder 23 rotates, it rotates the putty powder inside the material conveying trough 13 to the lower through groove 15 for pouring out.

[0025] In this embodiment, when in use: Holding the handle 6 and pushing forward, the first mounting block 3, via the platform 4, delivers a forward thrust to the rotating shaft 2 and wheel 1, causing them to rotate and move forward. When the rotating shaft 2 rotates, it drives the first pulley 9 on one side to rotate. The first pulley 9, through the transmission belt 10, drives the second pulley 11 to rotate, pouring putty powder into the hopper 22. The putty powder enters the rotating sleeve 14 through a through groove 15. When the second pulley 11 rotates, it drives the shaft 12 to rotate, causing the conveying cylinder 23 at one end to rotate along the inside of the rotating sleeve 14. The outer side of the conveying cylinder 23 is adjacent to the rotating sleeve. The inner wall of sleeve 14 fits perfectly to prevent putty from leaking out. The through groove 15 of the rotating sleeve 14 corresponds to the conveying trough 13 of the conveying cylinder 23. The putty powder in the feed bin 22 enters the interior of the conveying trough 13 through the upper through groove 15. When the conveying cylinder 23 rotates, it rotates the putty powder inside the conveying trough 13 to the lower through groove 15 for pouring out into the discharge port 16. The powder is then sprinkled out through the discharge port 16 to draw lines. Twisting the knob 21 causes the lead screw 19 to rotate. When the lead screw 19 rotates, it drives the switch plate 17 through the threaded hole 18 to move inside the feed bin 22, thereby controlling the opening and closing of the feed bin 22 and the continued feeding.
