[0026] See also Figures 1 to 5 A punching and binding machine with a positioning function according to a specific embodiment of the utility model comprises a base 1, a mounting bracket 2, a punching assembly 3, and a handle 4; two mounting brackets 2 are provided, and the two mounting brackets 2 are respectively arranged at the left and right sides of the base 1, and the two ends of the punching assembly 3 are respectively movably connected with the two mounting brackets 2; the handle 4 is U-shaped as a whole, and the two ends of the handle 4 are correspondingly fixedly installed on a rotating shaft 17 that is laterally rotatably arranged between the two mounting brackets 2, and a driving gear 18 is provided on the rotating shaft 17. Corresponding meshing holes 19 are evenly and vertically opened at corresponding positions on the punching assembly 3. The user swings the handle 4 around one end connected to the rotating shaft 17 to drive the rotating shaft 17 to rotate around its own axis, and then drives the driving gear 18 to rotate. The rotating driving gear 18 drives the punching assembly 3 to move vertically up and down by inserting its gear teeth into different meshing holes 19, thereby realizing the punching operation of the material laid on the base 1.

[0027] In addition, a handle shell 20 for easy holding is provided in the middle of the handle 4. The handle shell 20 adopts ergonomic design to facilitate the user to hold.

[0028] In this embodiment, the punching assembly 3 includes a plurality of vertically arranged and mutually parallel punching main boards, a plurality of punching ends correspondingly installed at the lower ends of each punching main board, and a meshing hole 19 correspondingly opened on the outer punching main board. The driving gear 18 correspondingly pushes the punching main board downward to make the punching end correspondingly open a hole downward, or pushes the punching main board upward to make the punching end withdraw to facilitate the replacement of materials. Moreover, each mounting bracket 2 is provided with a vertically extending movable channel 15, and the two side edges of the outer punching main board of the punching assembly 3 are correspondingly integrally provided with movable bars 16, and the vertical length of the movable channel 15 is greater than the vertical length of the movable bars 16. The punching assembly 3 also extends the movable bars 16 on both sides of the punching main board into the movable channel 15 and moves vertically in the movable channel 15 to correspond to the vertical lifting and lowering movement.

[0029] Furthermore, in the present embodiment, a cavity is provided at the left edge of the base 1, and two openings 6 are formed upward in the cavity. The positioning assembly 5 includes two positioning rods 7 respectively arranged at the two openings 6, and the two positioning rods 7 are also movably arranged in the cavity; both positioning rods 7 can be extended from the openings 6 under external drive to form a raised positioning point on the left side surface of the base 1, so that the material that has been punched can be positioned in cooperation with the positioning rods 7 by relying on the holes that have been punched, so as to facilitate subsequent punching and ensure consistent hole spacing.

[0030] In this embodiment, in order to adapt to holes of different shapes, the shapes of the upper end surfaces of the two positioning rods 7 are different, and the upper end surfaces of the two positioning rods 7 respectively correspond to the punching shape of a punching end of the punching assembly 3.

[0031] In addition, in order to facilitate the control of the lifting and lowering movement of the positioning rod 7, an adjustment button 9 is laterally movably arranged on the left side of the base 1. The adjustment button 9 includes a transverse movement button 10 that is laterally movably arranged on the left side wall of the base 1 and a transverse movement adjustment plate 11 that is arranged in the cavity and fixedly connected to the transverse movement button 10. A sliding channel 12 is also laterally opened on the transverse movement adjustment plate 11. The channel sections of the sliding channel 12 at different positions are not the same height. Adjustment pins 8 are correspondingly laterally arranged at the lower ends of the two positioning rods 7. Therefore, after the adjustment button 9 and the positioning rod 7 are installed in place and the adjustment pin 8 is inserted into the sliding channel 12 accordingly, when the transverse button 10 moves laterally, under the lateral limiting action of the physical structure at the opening 6 of the base 1, the adjustment pin 8 and the positioning rod 7 cannot move in the horizontal direction. Only when the adjustment pin 8 relatively enters the high section from the low section of the sliding channel 12 or enters the low section from the high section, the positioning rod 7 will move up and down synchronously with the adjustment pin 8. The user can control the lifting and lowering of the positioning rod 7 through the adjustment button 9 according to the above principle, so that the positioning rod 7 rises and protrudes from the base 1 to provide positioning for continuous punching of the material, or the positioning rod 7 drops and retracts into the cavity to facilitate material replacement.

[0032] Specifically, in this embodiment, the sliding channel 12 includes a high-position adjustment section 14 located in the middle and low-position adjustment sections 13 located on both sides. The high-position adjustment section 14 and the low-position adjustment section 13 are both horizontally extending strip-shaped through holes, but the height of the high-position adjustment section 14 in the vertical direction is greater than the height of the low-position adjustment section 13; therefore, when the transverse adjustment plate 11 is driven to move transversely by the transverse button 10, the adjustment pin 8 will drive the positioning rod 7 to descend when the relative transverse adjustment plate 11 enters the low-position adjustment section 13 from the high-position adjustment section 14, and will drive the positioning rod 7 to rise when the adjustment pin 8 enters the high-position adjustment section 14 from the low-position adjustment section 13 from the relative transverse adjustment plate 11.

[0033] In addition, in order to prevent the two positioning rods 7 from protruding from the surface of the base 1 at the same time to form double protruding positioning points and affect the continuous punching of paper, the shortest distance between the two low-position adjustment sections 13 is smaller than the distance between the two positioning rods 7; and without considering the size of the connecting transition end between the high-position adjustment section 14 and the low-position adjustment section 13, the shortest distance between the two low-position adjustment sections 13 can also be regarded as the length of the high-position adjustment section 14.

[0034] It should be noted that: in other embodiments, the number of cavities may not be limited to one, and two or more cavities may be provided on the base 1, and the number of positioning rods 7 may also be one or more, and only one positioning rod 7 or more than two positioning rods 7 may be provided in one cavity; in addition, one adjustment button 9 may be used only to vertically adjust one positioning rod 7. For example, two cavities are provided on the base 1, and one positioning rod 7 is provided in each of the two cavities, and an adjustment button 9 is provided on the outside of the two cavities, and the two adjustment buttons 9 are respectively used to control the lifting and moving of one positioning rod 7. In addition, two cavities may also be provided on the base 1, and two positioning rods 7 are provided in one cavity, and only one positioning rod 7 is provided in the other cavity, and two adjustment buttons 9 are provided on the outside of one cavity to respectively control the lifting and moving of the two positioning rods 7 in the cavity, and an adjustment button 9 is provided on the outside of the other cavity to respectively control the lifting and moving of the one positioning rod 7 in the cavity.

[0035] In addition, a return torsion spring 21 is also sleeved on the rotating shaft 17, one end of the return torsion spring 21 is connected to the handle 4, and the other end is fixed to the base 1 or the mounting bracket 2. The handle 4 swings downward to compress the return torsion spring 21, and the return torsion spring 21 elastically resets to cause the handle 4 to swing upward accordingly; and a return spring 22 is also connected between the mounting bracket 2 and the punching mainboard. When the punching mainboard moves downward, the return spring 22 is stretched to generate elastic force, and when the return spring 22 is reset and retracted, the punching mainboard can be pulled upward accordingly, so that the punching binding machine of this embodiment can be reused many times.

[0036] Furthermore, a protective shell 23 is provided on the base 1, and the protective shell 23 is covered on the base 1. The punching assembly 3 and the mounting bracket 2 are both located inside the protective shell 23. A suspended empty area is formed between the front side of the protective shell 23 and the base 1 to facilitate the material to extend under the punching assembly 3.

[0037] It should be noted that the hole punching and binding machine of this embodiment can be used not only for binding documents, but also for other purposes such as being used as a toy in a handmade market. Therefore, the materials corresponding to the hole punching and binding machine can be not only paper, but also plastic sheets or thin wood boards or thin sheets or boards made of other materials.

[0038] Anything not mentioned above is applicable to the prior art.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
