By holding the handheld rod 11, the device can be driven to work, after completing the dotting, the positioning cone 12 on one side of the protective cover 3 is aligned with the dotting position and is stuck, and another worker holds the rod body 1 on the side of the fixed cover 2 and moves to another dotting position to start the line drawing work.
[0024] Please refer to Figure 1 The rear ends of the fixed cover 2 and the protective cover 3 are both provided with a sliding groove 21, and the rear end of the line shooting mechanism 6 is slidably connected with the fixed cover 2 and the protective cover 3 through the sliding groove 21.

[0028] As another embodiment, as shown in Figures 4 to 6 The elastic line mechanism 6 includes a sliding plate 61, a sliding block 62, a sliding rod 63, a line clamp 64 and a trapezoidal hole 65; the sliding block 62 is inserted into the inner wall of the protective cover 3 at both ends, the sliding block 62 is slidably connected to the inner wall of the sliding plate 61, one end of the sliding rod 63 is inserted into the rear end of the sliding block 62, the other end of the sliding rod 63 is slidably connected to the sliding slot 21, the sliding rod 63 extends to the outside of the protective cover 3 through the sliding slot 21, the line clamp 64 is rotatably connected to the side of the sliding block 62 away from the sliding rod 63, and the trapezoidal hole 65 is arranged on the upper end of the sliding plate 61. The line clamp 64 is in contact with the inner wall of the sliding plate 61 on both sides when rotating, so as to limit the rotation of the line clamp 64 and prevent excessive rotation, a hole is arranged at the rear end of the sliding plate 61, the sliding rod 63 is connected to the sliding block 62 through the hole, and the sliding block 62 can drive the sliding rod 63 to displace synchronously.
[0029] As shown in Figure 5The wire clamp 64 comprises oppositely arranged clamp rods 641, clamp heads 642 and springs 643, the clamp rods 641 are rotationally connected with the sliding blocks 62 in a limited manner, the clamp heads 642 are weldedly connected with lower ends of the clamp rods 641, the two groups of clamp rods 641 are movably connected through the springs 643, and both ends of the spring 643 are inserted into the inner sides of the clamp rods 641. The clamp head 642 is located at the same horizontal position as the tensile wire 8, and the upper end of the sliding groove 21 is provided with an openable and closable limiting buckle, so that after the sliding rod 63 is pulled to slide to the upper end of the sliding groove 21, the wire clamp 64 can be fixed through the buckle to prevent it from moving downward under the action of gravity.
[0030] When the rod body 1 is in the working position, the tensile wire 8 forms a line segment between the dots, and the two ends of the working personnel are pulled downward by pulling the sliding rod 63, so that the sliding rod 63 drives the sliding block 62 to displace downward along the sliding plate 61, so that the clamp head 642 is in contact with the tensile wire 8, and the arc-shaped design of the clamp head 642 makes the clamp head 642 slightly rotate and open under the action of force, and the spring 643 is stretched, and the tensile wire 8 enters the clamp head 642 and is clamped.
[0031] Referring to Figure 5 The rear end of the clamp rod 641 is in an arc-shaped structure, the clamp rod 641 rotates when the rear end is limited by the trapezoidal hole 65 when the clamp rod 641 rises, the clamp head 642 is in an arc-shaped structure, and the clamp head 642 rotates under the influence of the arc-shaped structure when the clamp head 642 is in contact with the tensile wire 8. After the clamping of the clamp head 642 is completed, the sliding rod 63 is pulled to move upward, the sliding block 62 is slid upward along the sliding plate 61, and then the tensile wire 8 is driven upward by the wire clamp 64, so that the tensile wire 8 is stretched and accumulates potential energy. When the sliding rod 63 slides to the uppermost end, the rear end of the clamp rod 641 is in contact with the trapezoidal hole 65, the clamp rod 641 rotates under the limitation of the trapezoidal hole 65, so that the clamp head 642 is opened, the tensile wire 8 is released, and the tensile wire 8 hits the ground by inertia, and the carbon powder is used to draw lines on the ground.
[0032] Working principle: after completing the pre-dotting operation, after completing the dotting, the positioning cone 12 on one side of the protective cover 3 is inserted into the dotting position, and the other worker holds the rod body 1 on the side of the fixed cover 2 to displace to another dotting position. In this process, the fixed cover 2 drives the stretching line 8 to extend, so that the line wheel 4 rotates to send out the stretching line 8, and the fixed cover 2 drives the flexible side plate 7 to extend at the same time, so that the flexible side plate 7 forms protection on both sides of the stretching line 8. The two workers pull down the sliding rod 63, so that the sliding rod 63 drives the sliding block 62 to displace downward along the sliding plate 61, so that the chuck 642 contacts the stretching line 8, and the stretching line 8 enters the chuck 642 and is clamped; then pull the sliding rod 63 upward to drive the sliding block 62 to slide upward along the sliding plate 61, and then drive the stretching line 8 upward through the wire clamp 64, so that the stretching line 8 is stretched and accumulates potential energy. When the sliding rod 63 slides to the uppermost end, the rear end of the clamping rod 641 contacts the trapezoidal hole 65, and the clamping rod 641 rotates under the limiting of the trapezoidal hole 65, so that the chuck 642 is opened to release the stretching line 8. The stretching line 8 hits the ground by inertia, and the carbon powder is used to draw lines on the ground. After the line drawing is completed, the rod bodies 1 are close to each other, and the roller 51 rotates under the action of the torsional spring to retract the flexible side plate 7 and the stretching line 8.
[0033] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
