Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying fig. 1 to 6 of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

As shown in fig. 1-4, a portable hole punching device includes a base, a receiving groove 9 for receiving paper to be punched is formed at the rear end of the top of the base, and an opening 11 is formed in the receiving groove. The fixed subassembly of top front end installation of base, fixed subassembly extends to the top of storage tank 9 to the rear side. The fixing assembly is connected with the perforated pipe 7 in a sliding mode, the perforated pipe 7 is arranged in the vertical direction, and the perforated pipe 7 is located right above the opening hole 11. The rear end of the fixed component is hinged with a pressing plate 4, and the pressing plate 4 is positioned above the fixed component. A user can drive the perforated pipe 7 to move along the vertical direction by manually pressing the pressing plate 4 so that the perforated pipe 7 enters the opening 11, and therefore the purpose of perforating paper placed in the accommodating groove 9 is achieved, and the operation is convenient and fast; meanwhile, the device has the advantages of ingenious overall structure design, compact layout, small size and convenient carrying and use.

As shown in fig. 1, the base includes a bottom plate 1 and a supporting platform 2 located at the top of the bottom plate 1, the bottom plate 1 is flat, the bottom is smooth, the placing is stable, the area of the bottom of the supporting platform 2 is larger than that of the top, the supporting is more stable, and the accommodating groove 9 is arranged at the rear end of the top of the supporting platform 2. The fixed subassembly includes two fixed plates 3 of symmetry welding at 2 top front ends of a supporting bench, and two fixed plate 3 parallel arrangement, two fixed plates 3 all extend to the top of storage tank 9 to the rear side. The fixed plate 3 comprises a transverse plate section welded with the top of the support table 2 and a longitudinal plate section vertically connected with the transverse plate section. The fixing plate 3 is integrally bent and formed, the manufacturing process is simple, and the cost is low.

As shown in fig. 5, the longitudinal plate section is rotatably connected with the pressing plate 4 through the rotating shaft 8, the rotating shaft 8 movably penetrates through the longitudinal plate section and the pressing plate 4, and meanwhile, the end plates are welded at the two ends of the rotating shaft 8, so that the rotating shaft 8 is prevented from accidentally falling off. Suit torsional spring 5 on pivot 8, the both ends of torsional spring 5 respectively with press down board 4 and diaphragm section butt, under the natural state, when not exerting pressure according to board 4 promptly, torsional spring 5 is in the state of stretching naturally for the one end of keeping away from pivot 8 and fixed plate 3 according to board 4 are in the state of opening with the one end that keeps away from pivot 8. According to press and wear dress gag lever post 6 along the horizontal direction activity on the board 4, perforation pipe 7 activity suit is on gag lever post 6, when not pressing down press board 4, presses board 4 and takes perforation pipe 7 to keep away from storage tank 9 and trompil 11, and convenient to use person places the paper of treating the perforation in to storage tank 9.

As shown in fig. 5, a through hole 10 is formed through the bottom of the transverse plate section, the through hole 10 is located right above the opening 11, the perforated pipe 7 is movably arranged in the through hole 10 in a penetrating manner, and the through hole 10 plays a role in limiting and guiding the perforated pipe 7. Still the welding has spacing sleeve 12 on the horizontal plate section, and spacing sleeve 12 encircles through-hole 10 and arranges, and the activity of perforated pipe 7 is worn to adorn in spacing sleeve 12, further plays spacing guide effect to perforated pipe 7 for when pressing plate 4 applys the pressing force to perforated pipe 7, perforated pipe 7 can slide downwards in spacing sleeve 12 and through-hole 10, smoothly pierces through the paper of placing in storage tank 9 and gets into in the trompil 11.

As shown in fig. 6, a limiting open slot 13 is formed in the longitudinal plate section, and the end of the limiting rod 6 is movably inserted into the limiting open slot 13, so that a certain movement allowance is provided while the limiting rod 6 moves up and down. Of course, since the size of the device of the present invention is small, the movable ranges of the pressing plate 4, the stopper rod 6 and the perforated pipe 7 are very limited, and therefore, as long as the movable range is provided with a movable margin, the phenomenon that normal action cannot be performed due to mutual restriction does not occur.

The utility model discloses a theory of operation or application method: the device is small and exquisite as a whole, is convenient to carry, and can be carried to families and any office places for use. During the specific use, the base is placed in flat department, will treat that fenestrate paper puts into storage tank 9, puts the back, and manual pressing down is pressed according to board 4, and pressing according to board 4 exerts decurrent pressure to perforation pipe 7, and perforation pipe 7 moves down in spacing sleeve 12 and through-hole 10, runs through smoothly and gets into in trompil 11 behind the paper. After the perforation is finished, the hand pressing the pressing plate 4 is loosened, the compressed torsion spring 5 recovers, the pressing plate 4 is pushed to open, and the perforation pipe 7 is driven to upwards leave the opening hole 11 and upwards move in the through hole 10 and the limiting sleeve 12. And taking out the punched paper, putting in new paper, and repeatedly performing the next punching operation, so that the operation is very convenient and fast.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; the terms may be directly connected or indirectly connected through an intermediate medium, and may be used for communicating the inside of two elements or for interacting with each other, unless otherwise specifically defined, and the specific meaning of the terms in the present invention will be understood by those skilled in the art according to the specific circumstances.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
