DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] Example 1

[0022] See also Figure 1-4 A binding and punching device comprises a base 1, on which a pair of vertical rods 2 are symmetrically fixedly arranged, a horizontal plate 3 is fixedly installed on the top of the vertical rods 2, and a sliding sleeve 4 is slidably arranged on the vertical rods 2, and a plurality of movable parts 5 are fixedly installed on the sliding sleeves 4. A driving component for driving the movable part 5 to move up and down is also arranged on the base 1, a plurality of punching heads 23 are arranged on the bottom surface of the movable part 5, and an adjusting component for adjusting the spacing between the plurality of punching heads 23 is arranged in the movable part 5, the adjusting component comprises a roller 6 rotatably arranged in the movable part 5 and a plurality of sliders 8 slidably arranged in the movable part 5, a first knob 12 is installed at one end of the roller 6, and a plurality of slots 7 are opened on the roller 6, which In the embodiment, the middlemost groove 7 is vertically arranged, and the other grooves 7 are inclined, and the inclination angles of the grooves 7 are gradually increased. A lever 9 slidably matched with the groove 7 is fixedly arranged on the side of the slider 8. By arranging the movable part 5, the roller 6 and the plurality of sliders 8, when the roller 6 is driven to rotate, the cooperation between the plurality of grooves 7 on the roller 6 and the lever 9 on the side of the slider 8 can keep the position of the middlemost punching head 23 unchanged, and the plurality of punching heads 23 on the other two sides are adjusted at equal intervals. Compared with the prior art in which the positions of the plurality of punching heads 23 are manually adjusted, this structure has the advantages of convenient adjustment and high efficiency. In addition, compared with manual adjustment, the spacing adjustment accuracy between the punching heads 23 is higher.

[0023] A pair of guide rods 10 are symmetrically fixedly arranged in the movable part 5 , and a through hole 11 is opened on the slider 8 for slidingly cooperating with the guide rods 10 . The arrangement of the guide rods 10 further improves the stability of the slider 8 in horizontal sliding in the movable part 5 .

[0024] Among them, the driving assembly includes a vertical plate 16, a flip rod 17, a movable sleeve 18 and a connecting rod 21. The vertical plate 16 is fixedly installed on the base 1, and the two horizontal plates 3 are fixedly connected to the vertical plate 16. The flip rod 17 is rotatably installed on the vertical plate 16, and a strip hole 19 is opened on the flip rod 17. The movable sleeve 18 has a U-shaped structure. The movable sleeve 18 is clamped on the flip rod 17, and a pin shaft 20 that is slidably adapted to the strip hole 19 is installed on the movable sleeve 18. One end of the connecting rod 21 is hinged to the top surface of the movable part 5, and the other end is fixedly connected to the movable sleeve 18.

[0025] In addition, a handle 22 is installed on the side of the flip rod 17 away from the vertical plate 16. The provision of the handle 22 plays a role in saving effort.

[0026] Specifically, when using the device for punching, first place the text with holes to be punched on the base 1, and then adjust the spacing between the multiple punching heads 23 according to the width of the text. Specifically, by twisting the first knob 12 at the end of the movable part 5, the position of the middle punching head 23 remains unchanged, and the other multiple punching heads 23 on both sides are adjusted at equal intervals. After the adjustment is completed, just press the handle 22 downward. When the handle 22 drives the flip rod 17 to flip downward, the movable part 5 can be driven downward with the cooperation of the connecting rod 21 and the movable sleeve 18 to realize the punching operation of the text. After the punching is completed, just lift the flip rod 17 upward and take the text out of the base 1.

[0027] Example 2

[0029] See also Figure 2 and Figure 4 A threaded sleeve 13 is also fixedly embedded on the slider 8, and a screw 14 adapted thereto is installed in the threaded sleeve 13. The punching head 23 is fixedly installed at the bottom end of the screw 14, and the top end of the screw 14 is passed through the outside of the movable part 5 and is installed with a second knob 15. The arrangement of the threaded sleeve 13 and the screw 14 can adjust the number of holes punched according to needs. Specifically, by screwing the second knob 15, the second knob 15 drives the screw 14 to rotate, so that the punching head 23 can move up and down. When the punching head 23 is not needed, the punching head 23 can be controlled to move upward and hidden in the movable part 5, so as to adjust the number of punching heads 23, further improving the practicality of the device.
