[0031] A driving block 6 is arranged outside the fixed shaft 3 to drive the needle 2 to move and punch a hole;

[0032] The movable unit 7 is rotatably arranged outside the inner cavity of the roller 1, and the puncture needle 2 is movably arranged on the movable unit 7;

[0033] The transmission member 9 is movably arranged outside the roller 1, and when under pressure, it drives the movable unit 7 to move, thereby driving the needle 2 to always be perpendicular to the cloth when it is separated from the cloth;

[0034] The limit block 10 is arranged inside the roller 1 to limit the movable unit 7 from rotating inside the roller 1 .

[0035] A through groove is provided on the outside of the roller 1, and the movable unit 7 includes a rotating shaft 71 arranged in the through groove. Both ends of the rotating shaft 71 are fixedly connected to the roller 1, and a movable block 8 is provided on the outside of the rotating shaft 71. A torsion spring 72 is provided on the outside of the rotating shaft 71. The movable block 8 can be reset after moving by the torsion spring 72, and both ends of the torsion spring 72 are fixedly connected to the side wall of the through groove and the movable block 8 respectively.

[0036] The movable block 8 includes a fixed block 81 rotatably arranged on the outside of the rotating shaft 71, a fixed rod 82 is arranged on one side of the fixed block 81, a sleeve rod 83 is slidably arranged on the outside of the fixed rod 82, a return spring 84 is arranged in the sleeve rod 83, and both ends of the return spring 84 are fixedly connected to the sleeve rod 83 and the fixed rod 82 respectively.

[0037] A through hole is provided in the sleeve rod 83, and a fixed sleeve 11 is provided in the through hole. A movable plug 12 is movably provided in the fixed sleeve 11, and the piercing needle 2 is provided at the bottom end of the movable plug 12. A connecting spring 13 is provided in the fixed sleeve 11, and the two ends of the connecting spring 13 are respectively fixedly connected to the movable plug 12 and the inner wall of the fixed sleeve 11. A push rod 14 is provided at the top of the movable plug 12, and the push rod 14 movably penetrates the fixed sleeve 11 and an arc plate 15 is provided at the end. When aiming, the handgrip 5 drives the roller 1 to move. As the roller 1 moves, the driving block 6 squeezes the arc plate 15 in the roller 1 in sequence to move it. When the arc plate 15 moves, it drives the push rod 14 to move, and the push rod 14 drives the movable plug 12 and the piercing needle 2 to move, thereby making the piercing needle 2 punch a hole on the cloth. When the arc plate 15 is away from the driving block 6, under the action of the connecting spring 13, the connecting spring 13 is reset to drive the movable plug 12 and the piercing needle 2 to move, so that the piercing needle 2 shrinks into the fixed sleeve 11.

[0038] The transmission member 9 includes a plurality of transmission blocks 91 movably arranged on the outside of the roller 1. The plurality of transmission blocks 91 are evenly arranged on the roller 1 in a circumferential manner. One end of the transmission block 91 located on the outside of the roller 1 is an inclined surface. A side plate 92 is arranged on the inner wall of the roller 1. A compression spring 93 is arranged on the side plate 92. Both ends of the compression spring 93 are respectively fixedly connected to the side plate 92 and the transmission block 91. When the roller 1 continues to move, it will drive the plurality of transmission blocks 91 to contact the cloth in turn, thereby causing the cloth to be compressed and contracted into the roller 1.

[0039] A guide member 94 is also provided on the side plate 92, and an extrusion rod 95 is slidably provided in the guide member 94. The end of the extrusion rod 95 is rotatably connected to the sleeve rod 83. A wire plate 96 is also provided on the roller 1. A rope 97 is passed through the wire plate 96. The two ends of the rope 97 are respectively fixedly connected to the transmission block 91 and the extrusion rod 95. When the transmission block 91 is retracted into the roller 1, the transmission block 91 pulls the rope 97, and the rope 97 pulls the extrusion rod 95 to move. When the extrusion rod 95 moves, it can push the sleeve rod 83, thereby driving the sleeve rod 83 to extend outside the fixed rod 82 while rotating the fixed block 81, so that the movable block 8 is rotated to the outside of the roller 1, so that the needle 2 will not change its position with the movement of the roller 1, so that it remains perpendicular to the cloth and is located directly above the rolled hole for needle withdrawal.

[0040] The guide member 94 is a U-shaped guide rail fixedly arranged on the side plate 92, and the extrusion rod 95 is slidably arranged in the U-shaped guide rail.

[0041] The handle 5 includes a connecting rod 51 arranged on the rotating seat 4, a connecting sleeve 52 is movably arranged on the outer side of the connecting rod 51, a rubber sleeve 53 is arranged at the end of the connecting sleeve 52, a plurality of positioning holes 54 are opened on the connecting sleeve 52, a movable hole 55 is opened on the connecting rod 51, a supporting spring 56 is arranged in the movable hole 55, and a supporting block 57 used in conjunction with the positioning hole 54 is arranged at the end of the support spring 56. The handle 5 is retractable, which is convenient for adjusting the length. When adjusting, pressing the support block 57 to shrink it into the movable hole 55 can make the connecting sleeve 52 move freely on the outer side of the connecting rod 51. When the support block 57 moves to the next positioning hole 54, under the action of the support spring 56, the support block 57 re-enters the positioning hole 54 to position the connecting rod 51 and the connecting sleeve 52.

[0042] The outer side of the rubber sleeve 53 is provided with an anti-slip strip to facilitate holding during use.

[0043] In summary, when in use, the user holds the handle 5 to drive the roller 1 to move on the cloth. As the roller 1 moves, the driving block 6 squeezes the arc plate 15 in the roller 1 in turn to make it move. When the arc plate 15 moves, it drives the push rod 14 to move. The push rod 14 drives the movable plug 12 and the puncture needle 2 to move, so that the puncture needle 2 punches a hole on the cloth. When the arc plate 15 moves away from the driving block 6, under the action of the connecting spring 13, the connecting spring 13 is reset to drive the movable plug 12 and the puncture needle 2 to move, so that the puncture needle 2 shrinks into the fixed sleeve 11.

[0044] At the same time, during the tracing process, when the roller 1 continues to move, the needle 2 located directly below the roller 1 is located inside the rolled hole and perpendicular to the fabric. As the roller 1 continues to move, if the needle 2 is fixed on the roller 1, the roller 1 will drive the needle 2 to separate from the fabric and the needle 2 will tilt during this process, so that the root of the needle 2 is pulled away from the rolled hole, which will cause the fabric to tear. If it is a drawing, it may even cause the drawing to tear;

[0045] Therefore, when the roller 1 continues to move, the roller 1 will drive the transmission block 91 to approach the cloth. At this time, the transmission block 91 is compressed and retracted into the roller 1. When the transmission block 91 is retracted into the roller 1, the transmission block 91 pulls the rope 97, and the rope 97 pulls the squeezing rod 95 to move. When the squeezing rod 95 moves, it can push the sleeve rod 83, thereby driving the sleeve rod 83 to extend outside the fixed rod 82 while rotating the fixed block 81, so that the movable block 8 is rotated to the outside of the roller 1, so that the needle 2 will not change position with the movement of the roller 1, so that it remains perpendicular to the cloth and is located directly above the rolled hole for needle withdrawal. When the roller 1 continues to move, the transmission block 91 is no longer compressed, and then the movable block 8 and the sleeve rod 83 thereon are reset.
