[0022] The following will describe in detail the embodiments of the technical solutions of the present utility model with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0023] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0024] Such as Figures 1 to 4As shown in the figure, a specific embodiment of the present utility model provides a multi-directionally adjustable manual punching device, which includes a base 100. An operation surface is provided at the upper end of the base 100. Above the base 100, there is a punching machine body 200. A punching space 300 is formed between the lower end of the punching machine body 200 and the upper end of the base 100; several horizontally spaced heads 400 are provided in the punching machine body 200. A punching shaft 500 capable of sliding up and down in the vertical direction is provided in the head 400. A detachable punching knife 600 is installed at the lower end of the punching shaft 500. A gear 700 is provided in the head 400. The gear 700 meshes with a rack portion provided on the outer periphery of the punching shaft 500. A rotating shaft 800 horizontally passing through each gear 700 is provided in the punching machine body 200. Flange bearings 900 are provided on both sides of each gear 700 on the rotating shaft 800. An installation groove 210 for fitting the flange bearing 900 is provided on the inner side wall of the head 400. A limiting ring protrusion 910 abutting against the side wall of the head 400 is provided on the end surface of the flange bearing 900.

[0025] As Figures 1 to 4 shown, through the above settings, a punching space 300 for the punching material to pass through is formed between the upper end of the base 100 and the punching machine body 200 in this embodiment, so as to facilitate punching at any position of the material and improve the applicable range of the device; different numbers of machine bodies can be set in the punching machine body 200 according to needs. During the punching operation, by controlling the rotation of the rotating shaft 800, each gear 700 in the head 400 rotates to drive the punching shaft 500 to slide up and down in the vertical direction, and punching is completed by using each punching knife 600. Since flange bearings 900 are provided on both sides of the gear 700, and the flange bearings 900 are installed in the installation groove 210 on the inner side of the head 400, the assembly method from the inside to the outside and the abutment of the limiting ring protrusion 910 against the inner wall of the head 400 further improve the installation stability. The flange bearings 900 can ensure that the structure of the gear 700 remains highly stable, improving the punching accuracy and stability of the device.

[0026] As described above, in this embodiment, the punching structure makes the punching shaft 500 move downward by rotating the rotating shaft 800. In order to make the punching shaft 500 automatically reset after moving downward, a spring member 1000 is sleeved on the punching shaft 500 in this embodiment, and an adjusting nut 1100 is screwed on the upper end of the punching shaft 500. The lower end of the spring member 1000 abuts against the inside of the head 400, and the upper end abuts against the adjusting nut 1100. In this way, after the punching shaft 500 moves downward, the spring is compressed to accumulate elastic force, and after punching is completed, the punching shaft 500 moves upward under the action of the elastic force to achieve automatic reset.

[0027] As Figures 1 to 4As shown in the figure, in order to facilitate the rotation of the rotating shaft 800, in this embodiment, a control handle 1200 with a U-shaped structure is provided outside the punching machine body 200, and both ends of the control handle 1200 are fixedly connected to the corresponding end of the rotating shaft 800. During operation, the rotating shaft 800 can be driven to rotate by pressing down the control handle 1200, making the punching operation more labor-saving. In practical applications, the cross-section of the rotating shaft 800 is polygonal, such as a regular pentagon, a regular hexagon, etc., and the machine head 400 can achieve sliding adjustment of the spacing and can drive the gear 700 to rotate.

[0028] As Figures 1 to 4 shown in the figure, since the punching spacing of materials with different specifications is different, it is necessary to adjust flexibly according to the materials. In this embodiment, a horizontally arranged strip-shaped installation groove 210 is provided at the rear side of the punching machine body 200 corresponding to each machine head 400. A fixing plate 1300 is provided on the rear side surface of the punching machine body 200, and a fixing bolt passing through the installation groove 210 is provided on the fixing plate 1300. A strip-shaped punching groove 220 for the punching knife 600 to pass through is provided at the lower end of the punching machine body 200. In this way, after the machine head 400 slides to the appropriate position along the installation groove 210, the machine head 400 is fixed by the fixing plate 1300, which is not only convenient for adjustment but also has higher stability after fixation.

[0029] As Figures 1 to 4 shown in the figure, a tool hole for installing the punching knife 600 is provided at the lower end of the punching shaft 500, and a disassembly bolt 1400 for fixing the punching knife 600 is provided outside the punching shaft 500. When the punching knife 600 is installed, the upper end is inserted into the tool hole, and the disassembly bolt 1400 fixes the punching knife 600. It is convenient for disassembly and replacement and has good stability at the same time. The punching knife 600 adopts a hollow tool head and should be replaced when it is worn after long-term use.

[0030] As mentioned above, a gap needs to be set between the base 100 and the punching machine body 200 to form a punching space 300. In this embodiment, heightening seats 1500 are provided on both sides of the upper end of the base 100, and the upper ends of the heightening seats 1500 are fixedly connected to the lower end of the punching machine body 200. The heightening seats 1500 can make the punching machine body 200 higher than the base 100 for installation.

[0031] As Figures 1 to 2 shown in the figure, gaskets 1600 are provided on the operation surface of the base 100 corresponding to the lower sides of the punching knives 600, and the gaskets 1600 are fitted in the gasket grooves provided at the upper end of the base 100. The gaskets 1600 can increase the friction at the punching position and keep the paper materials to be punched stable. Since the punching knives 600 will pass through the gaskets 1600, the gaskets 1600 need to be replaced after long-term use. The gaskets 1600 can be made of rubber sheet materials.

[0032] As Figures 1 to 2As shown, a first paper stopper slider 1700 is slidably provided on one side of the upper end of the base 100, and a second paper stopper slider 1800 is slidably provided on the lower middle portion of the upper end of the base 100 corresponding to the punching machine body 200. The paper stopper can be abutted against the outer surface of the material to play a limiting role; each paper stopper slider structure can be slidably installed and fixed by a screw structure to play an adjustment role, which is convenient for the operator to control. A scale mark is also required to be set on the upper end of the base 100 to facilitate the positioning operation of precise punching.

[0033] like Figure 1 As shown, when performing the punching operation, it is necessary to ensure that the base 100 remains stable, so in this embodiment, an array of support pads 1900 are provided at the lower end of the base 100 .

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
