The second through holes 320 are connected to the extrusion groove 310 and are connected to the first through holes 111. One-to-one correspondence; multiple punching members 400 are all arranged in the extrusion groove 310, one punching member 400 corresponds to a second through hole 320, at least part of the punching member 400 is located in the second through hole 320, and one end of the punching member 400 facing the second through hole 320 is provided with a punching portion 410, and the other end of the punching member 400 is limitedly arranged in the extrusion groove 310; the elastic member 500 corresponds to the punching member 400 one-to-one, and the elastic member 500 is sleeved on the outer peripheral surface of part of the punching member 400 , and is located between the bottom of the extrusion groove 310 and the end of the punching member 400 away from the second through hole 320; wherein the punching member 400 is configured as follows: when the rotating rod 200 rotates toward the punching area 110, a side of the fixed shell 300 facing the base 100 abuts against the punching area 110, the rotating rod 200 continues to rotate and squeezes the punching member 400, and compresses the elastic member 500, so that the punching portion 410 passes through the second through hole 320 and enters the first through hole 111.

[0040] In this embodiment, the base 100 is in the shape of a rectangular parallelepiped, and a punching area 110 and a rotating part 120 are provided on the top surface of the base 100. The rotating part 120 includes protrusions that are opposite and spaced along the second direction, and the protrusions are provided with a first rotating through hole along the second direction. The punching area 110 is provided with a first through hole 111 axially along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0041] A first connecting through hole is provided on both sides along the second direction at one end of the rotating rod 200, and the first connecting through hole is aligned with the first rotating through hole, and a pin is inserted therein, so that the rotating rod 200 is connected to the rotating part 120 for rotation. A second rotating through hole is also provided on both sides along the second direction at one end of the rotating rod 200, and the second rotating through hole is located between the first connecting through hole and the other end of the rotating rod 200.

[0042] The fixed shell 300 is in the shape of a rectangular parallelepiped, and second connecting through holes are provided on the two side surfaces of the fixed shell 300 along the second direction. The second connecting through holes are aligned with the second rotating through holes, and pins are inserted to realize that one end of the fixed shell 300 is connected to the rotating rod 200 for rotation, and an avoidance through hole is provided at one end of the fixed shell 300 for avoiding the rotating rod 200.

[0043] The punching member 400 is used for punching holes and is in the shape of a nail. The two ends of the punching member 400 are squeezed and fixed by the elastic member 500 and the rotating rod 200 respectively. When the rotating rod 200 squeezes the punching member 400, the punching member 400 compresses the elastic member 500, and at least part of the punching member 400 is located in the second through hole 320. The second through hole 320 will limit the movement of the punching member 400, and guide the punching member 400 to move only along the axial direction of the second through hole 320, so that the punching portion 410 of the punching member 400 finally passes through the second through hole 320 and cuts the bill until it enters the first through hole 111, and the punching of the punching member 400 is completed. The elastic member 500 is a spring.

[0044] It is worth understanding that the bill is placed on the punching area 110 on the top surface of the base 100, and then the rotating rod 200 is driven to rotate toward the punching area 110, so that the side of the fixed shell 300 facing the punching area 110 first contacts the bill on the punching area 110 and squeezes and fixes the bill. Then, the rotating rod 200 continues to rotate and squeezes the other end of the punching member 400 limited in the squeezing groove 310, so that the punching member 400 moves along the axial direction of the second through hole 320. When the punching portion 410 of the punching member 400 contacts the bill, the punching portion 410 cuts the bill. A through hole is formed. After the punching part 410 moves into the first through hole 111, the punching part 410 penetrates all the bills to complete the punching. During the punching process, the bills are pre-fixed by squeezing the fixed shell 300, thereby improving the punching accuracy. After punching, pressure is provided by the rotation of the rotating rod 200. When rotating, the rotating rod 200 will first contact the punching piece 400 closest to the rotating part 120, and then contact other punching pieces 400 in sequence along the first direction, thereby realizing sequential punching, which is more labor-saving, and multiple holes can be formed at one time, with higher punching accuracy.

[0045] Reference Figure 2 and Figure 5 As shown, in some specific embodiments of the present invention, a waste cavity 130 for placing waste is provided in the base 100 , and the waste cavity 130 is connected to the first through hole 111 .

[0046] It should be noted that after cutting, waste material from bill cutting will remain in the first through hole 111. The waste material after cutting is collected through the waste chamber 130, and there is no need to specially clean the waste material in the first through hole 111. The waste material will not hinder cutting in the first through hole 111, and the overall use of the punching device is more convenient.

[0047] Reference Figure 2 and Figure 5 As shown, in some specific embodiments of the present invention, a plurality of partitions 131 are disposed in the waste chamber 130 along the first direction, and sub-cavities are formed between adjacent partitions 131 , and the sub-cavities are connected to at least one first through hole 111 .

[0048] It is worth to understand that the multiple partitions 131 form a sub-cavity to evenly distribute the waste material, thereby preventing the waste material from accumulating at a certain position of the waste cavity 130 and causing the waste material to be unusable.

[0049] Reference Figure 2 and Figure 5 As shown, in some specific embodiments of the present invention, the base 100 includes a main body 140 and a perforated plate 150, a waste chamber 130 is provided in the main body 140, a first opening connected to the waste chamber 130 is provided on the top surface of the main body 140, and the perforated plate 150 is installed at the first opening.

[0050] It is worth understanding that the waste in the waste chamber 130 can be poured out by disassembling the perforated plate 150, and the perforated plate 150 is separately arranged from the main body 140, which makes the manufacturing difficulty lower and more convenient, and it is also convenient to replace the perforated plate 150 when it is damaged.

[0051] In addition, after the perforated plate 150 is placed, the partition 131 can also play a role in supporting the perforated plate 150, so that the perforated plate 150 can withstand higher pressure.

[0052] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the base 100 includes a main body 140 and a side panel 160, a waste chamber 130 is provided in the main body 140, a second opening connected to the waste chamber 130 is provided on the side of the main body 140, and the side panel 160 can be detachably installed on the second opening.

[0053] It is worth understanding that a detachable side plate 160 is provided on the side of the main body 140, and the side plate 160 does not affect the supporting effect of the main body 140 on the punching plate 150, and after the side plate 160 is removed, it is more convenient to pour out the waste in the waste cavity 130, and it is more convenient to use. Among them, the side plate 160 is fixed to the side of the main body 140 by magnetic attraction.

[0054] Reference Figure 2 and Figure 4As shown, in some specific embodiments of the present utility model, the rotating rod 200 includes a main rod portion 210 and an extrusion portion 220 connected to the main rod portion 210, one end of the main rod portion 210 is rotatably connected to the rotating portion 120, the main rod portion 210 is provided with a rotationally connected to the fixed shell 300, the extrusion portion 220 is located between the main rod portion 210 and the base 100, the extrusion portion 220 is set at an angle to the main rod portion 210, and is limited in the extrusion groove 310, and the extrusion portion 220 is limited to abut against the other end of the punching member 400.

[0055] It is worth understanding that the rotating rod 200 can better squeeze the punching member 400 in the squeezing groove 310 through the squeezing portion 220, and the main rod portion 210 can be located outside the squeezing groove 310 when the squeezing portion 220 squeezes, which is convenient for human hand holding and more convenient to use. In addition, the squeezing portion 220 is limited in the placement groove and cannot escape from the placement groove. When the rotating rod 200 rotates in a direction away from the punching area 110, the rotating rod 200 rotates together with the squeezing groove 310 through the squeezing portion 220, so that the fixed shell 300 also rotates in a direction away from the punching area 110, and the fixed shell 300 is separated from the bill, which is convenient for taking away the bill on the base 100.

[0056] In this embodiment, the angle between the extrusion part 220 and the main rod part 210 is 16°, and can be any angle value between 10° and 30°. A plurality of support rods are also provided between the main rod part 210 and the extrusion part 220 to strengthen the connection strength between the main rod part 210 and the extrusion part 220.

[0057] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, a gripping handle 211 is provided at one end of the main rod portion 210 away from the rotating portion 120 .

[0058] It is worth understanding that the main rod 210 is convenient for the user to hold by means of the gripping handle 211 , so that the user can rotate the main rod 210 and apply pressure to the punching member 400 , which saves the user effort when using the main rod 210 .

[0059] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, one end of the extrusion portion 220 away from the main rod portion 210 extends into the extrusion groove 310, and the notch of the extrusion groove 310 is provided with a stop portion 311 extending toward the rotating portion 120 at the end away from the rotating portion 120, and the end of the extrusion portion 220 away from the main rod portion 210 can abut against the stop portion 311.

[0060] It is worth to understand that the pressing part 220 is limited in the placement groove by abutting against the stopper 311, so that the pressing part 220 can drive the fixed shell 300 to move together, making it more convenient to take out the bill.

[0061] As another implementation, a stopper 311 may be provided between the two ends of the placement groove to limit the extrusion portion 220 .

[0062] Reference Figure 1 As shown, in some specific embodiments of the present invention, a plurality of guide rings 312 are disposed in the extrusion groove 310 . The guide rings 312 correspond to the second through holes 320 one by one and surround the second through holes 320 .

[0063] It is worth understanding that the axial length of the second through hole 320 is increased by the guide ring 312 to prevent the punching member 400 from slipping out of the second through hole 320 , which can better limit the punching member 400 and make it more reliable to use. The guide ring 312 can guide the punching member 400 by extending the second through hole 320 .

[0064] Reference Figure 3 and Figure 6 As shown, in some specific embodiments of the present invention, the punching member 400 includes a nail rod portion 420 and a nail cap portion 430 connected to one end of the nail rod portion 420, the other end of the nail rod portion 420 is provided with a punching portion 410, and the elastic member 500 is sleeved on the outer peripheral surface of the nail rod portion 420, one end of the elastic member 500 abuts against the nail cap portion 430, and the other end abuts against the bottom of the extrusion groove 310.

[0065] It is worth understanding that the nail rod portion 420 slides axially along the second through hole 320, the nail cap portion 430 abuts against the elastic member 500, and the nail cap portion 430 bears the extrusion force of the extrusion portion 220. When the nail cap portion 430 is squeezed, the nail rod portion 420 is driven to slide axially along the second through hole 320, and passes through the bill and enters the first through hole 111, thereby realizing punching of the bill.

[0066] During the punching process, the elastic member 500 contracts and has a certain elastic potential energy. After the punching is completed, the extrusion part 220 rotates in a direction away from the punching area 110, and the elastic member 500 releases the elastic potential energy, driving the nail cap part 430 to move in a direction away from the base 100, thereby driving the nail rod part 420 to contract back into the second through hole 320 in a direction away from the base 100, and the punching part 410 will also be located in the second through hole 320. When the fixed shell 300 contacts the bill, the punching part 410 does not contact the bill. Only after the fixed shell 300 squeezes the bill in the punching area 110 of the base 100, the punching part 410 will extend out of the second through hole 320 for punching. The punching member 400 has higher safety performance in use.

[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
