Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] Example:

[0048] like Figure 1-5 As shown, the present application discloses a punching pliers suitable for processing multiple specifications, which can be used for processing multiple specifications of holes. Specifically, the punching section and the cutter head of the punching pliers are improved, and the remaining parts are the existing structure and will not be described here in detail. The specific structure is described in detail below;

[0049] like Figure 1 、 2 As shown, the present application discloses a punching pliers suitable for multi-specification processing, comprising:

[0050] The outer shell component 1 mainly plays a protective role and can be used to protect the internal parts such as the cutter head component 2;

[0051] The cutter head assembly 2 is installed inside the housing assembly 1 and is mainly used for subsequent punching processing;

[0052] The hole-changing mechanism 3 is slidably provided on the housing assembly 1, and the hole-changing mechanism 3 cooperates with the cutter head assembly 2. The hole-changing mechanism 3 is slidably adjustable and is used to complete the punching operation after cooperating with the cutter head assembly 2. The punching pliers of the present application also include other components to achieve the punching function, which are existing components or structures and are not described in detail here.

[0053] The housing assembly 1 includes a bottom shell 101, and a sliding groove 102 is provided on the side of the bottom shell 101 facing the cutter head assembly 2. The bottom of the bottom shell 101 is preferably flat to facilitate stable assembly of the present application. Figure 1 From above, the upper surface of the bottom shell 101 is provided with the sliding groove 102, and the punch of the cutter head assembly 2 faces downwards, and can cooperate with the slider located inside the sliding groove 102 to complete the punching operation;

[0054] The hole-changing mechanism 3 includes a slider 301 , which is slidably disposed in the sliding groove 102 . The slider 301 is adjustable to meet different needs of customers.

[0055] Compared with the existing slider, in this application, the slider 301 is provided with multiple standard holes 302 at intervals. When the slider 301 slides along the sliding groove 102, different standard holes 302 can cooperate with the cutter head assembly 2 to meet different needs.

[0056] In order to meet different punching requirements, such as Figure 5 As shown, this application also requires the design of the specification hole 302. The inner diameter of the specification hole 302 gradually decreases along the length direction of the slider 301. The staff using it can adjust it according to the use requirements, and also have corresponding adjustment expectations and know the direction of adjustment, so as to improve work efficiency.

[0057] Specifically, the number of standard holes in this application can be 2, 6 or other numbers.

[0058] The slider 301 in the present application can be locked by a bolt when it slides to the corresponding position, or it can also be locked by the following method: the inner wall of the sliding groove 102 is provided with a plurality of locking holes 103 at intervals along its length direction. The specific shape of the locking holes 103 can be semicircular, rectangular or other shapes;

[0059] The hole-changing mechanism 3 also includes a plurality of locking protrusions 303, which are arranged at intervals on both sides of the slider 301, and the locking protrusions 303 are distributed along the length direction of the slider 301. The locking protrusions 303 cooperate with the locking holes 103, and when they are inside the locking holes 103, the locking is completed; when adjustment is required, the slider 301 is pushed to move so that it leaves the locking hole 103 to complete the adjustment; because the position of the slider 301 needs to be adjusted, the number of locking protrusions 303 on the same side of the slider 301 is greater than the number of locking holes 103 to achieve adjustable position.

[0060] In one embodiment, if Figure 5 As shown, the locking protrusion 303 is an elastic protrusion, which can facilitate smooth adjustment. At the same time, the elastic protrusion can also emit sound feedback to provide a prompt.

[0061] Regarding the cutter head assembly of the punch pliers, this application has also made certain improvements, such as Figure 2-4 As shown, the cutter head assembly 2 includes:

[0062] The cutter head holder 201 is mounted on the bottom shell 101 and is specifically connected in a fixed manner;

[0063] The cutter head unit 202 is installed inside the cutter head frame 201, specifically between the pressing shell 203 and the cutter head frame 201;

[0064] One end of the pressing shell 203 is movably connected to the cutter head holder 201, specifically through a torsion spring, or can also be connected in other ways.

[0065] In one embodiment, downwardly extending wrapping sections 204 are provided on both sides of the pressing shell 203 , and the wrapping sections 204 are located on the outside of the cutter head holder 201 . The wrapping sections 204 ensure the stability of the assembly structure of the cutter head unit 202 .

[0066] The two sides of the tool head holder 201 are provided with vertical adjustment slots 205, and the wrapping section 204 is provided with a horizontal matching slot 206 corresponding to the adjustment slot 205. The directions of the two slots are perpendicular to each other to avoid interference.

[0067] The cutter head unit 202 includes a cutter head shaft 207 and a locking button 208. The two ends of the cutter head shaft 207 pass through the adjustment slot 205 and the matching slot 206 respectively, and the locking button 208 is installed at one end of the cutter head shaft 207. The locking button 208 is located on the outside of the wrapping section 204. In this application, the cutter head unit 202 is assembled inside the cutter head frame 201, and the cutter head shaft 207 slides in the adjustment slot 205 and the matching slot 206, and the locking button 208 can complete the locking.

[0068] Among them, Figure 2 As shown, the cutter head unit 202 further includes:

[0069] A chuck 209 is mounted on the cutter head shaft 207;

[0070] A plurality of cutter heads 210 are spaced apart and distributed along the circumferential direction of the chuck 209 . The diameters of the cutter heads 210 are all different, that is, different holes can be processed by using different cutter heads 210 .

[0071] When using this application, if different specification holes need to be processed, the slider 301 is pushed to make the different specification holes cooperate with the cutter head unit 202, and the cutter head unit 202 is adjusted so that the corresponding cutter head is aligned with the specification hole, which facilitates the subsequent processing of the corresponding specification holes.

[0072] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details.
