Specific implementation

[0029] The technical scheme in the utility model embodiments will be described clearly and completely in conjunction with the drawings of the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] As Figures 1-4The multipurpose puncher is erected on a desktop or a table top, and is more labor-saving when punching. The front end has a ruler function during writing or drawing, and can measure or draw required items. The puncher is internally provided with three or more punches. The upper cover of the puncher is provided with a mechanism for locking the upper cover, thereby saving the space occupied by the puncher.

[0031] The guide hole support, the cutter group, the lower pressing cover plate 4 and the base plate 6 are composed. The puncher can punch three or more holes, and is integrated with a measuring tool. The structure is simple, easy to assemble, maintain and replace parts, comfortable and safe to use, improves efficiency and is easy to clean. The specific structure is as follows:

[0032] Referring to Figure 4 , 5 The guide hole support is composed of a lower plate 1 and an upper clamping block 2. The lower plate 1 and the upper clamping block 2 form a side clamping gap 23. A plurality of cutter holes 11 pass through the lower plate 1 and the upper clamping block 2 and pass through the side clamping gap 23. The cutter hole 11 of the upper clamping block 2 is provided with a hole seat 22 extending upward, which has a lifting guide effect.

[0033] The bottom of the upper clamping block 2 is a stepped groove 21. The stepped groove 21 and the lower plate 1 form a clamping gap for placing a paper to be punched.

[0034] A side support 24 is located on both sides of the guide hole support, specifically on both sides of the upper clamping block 2. The side support 24 is provided with an axle hole groove 25 and a guide sliding groove 26.

[0035] In this embodiment, the lower plate 1, the upper clamping block 2 and the side support 24 are an integrated die-casting support.

[0036] The cutter group, referring to Figure 6 , is composed of three punching knives 31 and a synchronous shaft 32. The synchronous shaft 32 is connected with each punching knife 31, so that the three punching knives 31 form synchronous movement. The two ends of the synchronous shaft 32 are located in the guide sliding groove 26 and can move up and down in the guide sliding groove 26, driving the entire cutter group to move integrally. The punching knife 31 is gap-fitted with the hole seat 22.

[0037] The lower pressing cover plate 4 has downwardly extending side positioning edges 41 covering the guide hole support. The side positioning edges 41 are provided with central fulcrum holes 42 for installing a fixed shaft 46. The fixed shaft 46 passes through the central fulcrum holes 42 on both sides and the axle hole groove 25. The lower pressing cover plate 4 forms a rotating pressing mechanism with the fixed shaft 46 as the center.

[0038] The side positioning edges 41 are provided with guide point holes 43 for installing the synchronous shaft 32. After the synchronous shaft 32 passes through the guide sliding groove 26, the two ends are installed in the guide point holes 43. The lower pressing cover plate 4 drives the synchronous shaft 32 to move.

[0039] The shaft hole groove 25 has an open front end, which allows the fixed shaft 46 to slide laterally. Since the movement of the tool assembly is a linear lifting motion, rather than an arc motion with the fixed shaft 46 as the center, the shaft hole groove 25 is set to have an open front end, so that the fixed shaft 46 has enough lateral adjustment space to make the linear lifting motion of the tool assembly smooth.

[0040] See Figure 3 Two auxiliary pressure ribs 44 are located on the bottom surface of the lower pressure cover plate 4, alternating with the adjacent pressure hole cutters 31 and contacting the synchronous shaft 32 to provide downward pressure support. The lower pressure cover plate 4 extends rearward to form a force-saving lever. The extended area is used to support the downward pressure, and the extension length is equivalent to extending the lever arm. The longer the lever arm, the less effort is required to operate.

[0041] The lower pressure cover plate 4 has a front limiting edge 45, and its two ends are connected to the side positioning edge 41 to form a whole; the reset torsion spring 5 is sleeved on the fixed shaft 46, and the two end torsion arms are respectively attached to the inner wall of the lower pressure cover plate 4 and the upper part of the upper clamping block 2, and the upward elastic force on the lower pressure cover plate 4 keeps the lower pressure cover plate 4 in the state before drilling.

[0042] Specifically, the upper torsion arm of the reset torsion spring 5 is attached to the front limit edge 45, and the torsion arm has a bent extension to increase the contact surface and improve the elastic effect.

[0043] See Figure 7 The base plate 6 has an internal cavity 61 that can accommodate the punching knife 31 when the lowering point is reached, and store punching waste paper scraps; the upper part has a countersunk groove structure with an opening slot 62 for installing the guide hole bracket.

[0044] The base plate 6 has extension plates 64 on both sides, making the base plate 6 have a "T" shaped structure. The extension plates 64 have scales to form a measuring ruler, which can be used as a measuring stationery.

[0045] The synchronous shaft 32 can slide left and right. The punch 31 has a through hole in its middle, through which the synchronous shaft 32 enters. One end of the synchronous shaft 32 has a locking step 33, and the bottom end of the guide groove 26 has a locking groove 27, forming a locking mechanism for the lower cover plate 4. In use, when the synchronous shaft 32 is pressed down into the locking groove 27, pushing the synchronous shaft 32 causes the locking step 33 to enter the locking groove 27, creating a locking effect and saving space occupied by the punch. (See also...) Figure 2 After locking, the rear side of the base plate 6 is aligned with the rear end of the lower cover plate 4, saving space during placement.

[0046] See Figure 4 The lower plate 1 can be equipped with a snap-fit ​​12 around its perimeter, and the side edge of the bottom plate opening slot 62 is equipped with a corresponding snap-fit ​​groove 63, which can be snapped into the side edge snap-fit ​​groove 63 of the bottom plate opening slot 62 for easy installation.

[0047] Specifically, the front end of the lower plate 1 has a buckle position 12, which can be buckled into the side of the open slot 62 of the bottom plate; further, the lower plate 1 and the upper clamping block 2 of the guide hole support have through positioning holes, the open slot 62 of the bottom plate is provided with a threaded hole 65, and after installation, the positioning hole is sleeved on the threaded hole 65, and after the threaded hole 65 is installed with a screw, the guide hole support and the lower plate 1 are fixed.

[0048] Referring to Figure 4 The bottom of the base plate 6 is provided with a rubber pad 7, and the base plate 6 and the rubber pad 7 are attached to form a containing cavity 61, which has a paper scrap storage function; the outer peripheral edge of the base plate 6 is a downward flanging structure, so as to be attached with the rubber pad 7 to form the containing cavity 61. Moreover, the base plate 6 and the rubber pad 7 have a plurality of buckling points 71 and buckling holes, which are convenient for installation. The bottom has a flip opening, which can be opened to pour out the punched waste paper scraps.

[0049] In the embodiment, the flip cover 72 is arranged on the rubber pad 7, and a flange is arranged between the flip cover 72 and the rubber pad 7.

[0050] In the embodiment, the rubber pad 7 is made of PP folding rubber, which ensures that the flip cover 72 of the containing cavity 61 is not broken when opened and closed.
