Abstract
The utility model discloses a cutter structure of use on puncher, including the cutter body of cylinder type structure, the lower extreme of cutter body sets up for the slope, and the lower extreme of cutter body is provided with the notch of cylinder type, and the notch edge be sharp -pointed cutting edge, and the notch bottom surface is provided with the shoulder hole, and the spring is installed to aperture on the shoulder hole includes the macropore and lies in the macropore in, big downthehole install that the diameter is greater than the aperture diameter and is lighter than the macropore diameter move back the bits pole, the one end card of spring is in the aperture, the other end of spring is considered the pole to be worth doing and is connected with moving back. The diameter that moves back the bits pole is greater than aperture diameter and be less than the macropore diameter, and it can only be at the macropore internalization to move back the bits pole, and the motion scope of moving back the bits hole is limited, and effective control spring's decrement can effectively improve the life of spring. The cutter body adopts cylinder type structure, no matter be the surface cut groove at the cutter body, still the surface at the cutter body punches, all can not influence its holistic structural strength, simply the various puncheres of adaptation.
Description
Technical field
The utility model relates to a kind of novel office table separation, especially relates to a kind of cutter structure be used on puncher.
Background technology
In official documents and correspondence arrangement process, generally can use puncher at present, paper be had openning hole and is bound up again.Puncher conventional in office is the puncher of plain type, and puncher is provided with a piercing knife, the top of piercing knife can compress force by a driving mechanism.When paper perforating, piercing knife moves in Paper Diego along its y direction, and carries out gradual punching in aperture periphery, makes piercing knife form hole in Paper Diego place.
The piercing knife structure of existing paper punch, is form a sharp keen reverse V-shaped groove otch in the bottom of piercing knife mostly, makes it can form two cut points and cut.But this structure piercing knife is in actual use, find also laborsaving not, thicker at the paper of required punching, or when needing to beat multiple hole simultaneously, use the piercing knife of said structure, the power of required applying is just comparatively large, and user is more painstaking in drill process.
Perforating machine cutter structure disclosed in Chinese invention patent application prospectus CN200910262129.9, comprises body, and described body is the cylindrical shell of a hollow tank, formed in cutter bottom a tool cutting edge, for cutting the angle cutter edge wearing paper perforating.This cutter also comprises: a tank, is formed in this cutter; One spring, is installed in this tank; One exit for paper scrap move back bits bar, being located in this tank, pulls this spring in top, upper end.Test of many times proves, adopts angle cutter edge to replace reverse V-shaped groove otch effectively can reduce the power of required applying when puncher punches.But adopt the perforating machine cutter structure disclosed in this description, there are the following problems again: the cylindrical shell 1, adopting hollow tank, this structure can only be applicable to be provided with cross-drilled hole in the middle part of cutter, the structure connected with puncher by cross-drilled hole.But in fact, in the middle of the use of puncher, is mostly adopt to offer an annular groove in the periphery of cutter, annular groove arranges jump ring and is connected with puncher.The wall at annular groove place can be made excessively thin if the cylindrical shell of hollow-core construction offers annular groove again on its surface, cause overall construction intensity inadequate.Not to spring and move back bits bar and carry out spacing in the cutter of 2, this structure, when being subject to larger pressure, move back bits bar and be pressed in cutter, the compressed shape variable that spring occurs is very large.Under Long-Time Service, easily cause spring to follow the string, move back bits bar and normally cannot move back bits.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cutter structure be used on puncher, can the installation environment of adaptive puncher, and effectively improves cutting-tool's used life.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cutter structure be used on puncher, comprise the cutter body of cylindrical structure, the lower end of described cutter body is for being obliquely installed, the lower end of cutter body is provided with the notch of column type, described notch edges is sharp-pointed blade, described notch bottom surface is provided with shoulder hole, described shoulder hole comprises macropore and is positioned at the aperture on macropore, in described aperture, spring is installed, be provided with in described macropore diameter be greater than hole diameter and be less than diameter macropores move back bits bar, one end of described spring is stuck in aperture, the other end of spring is considered bar to be worth doing and is connected with moving back.
Described bits bar entirety of moving back is cylindrical-shaped structure, the described upper end of moving back bits bar is provided with Access Division, carry out clamping in the other end that described Access Division snaps in spring, the described lower end of moving back bits bar is frustum cone structure, and the diameter moving back the bottom surface of bits bar is less than the diameter in the middle part of it.The connection of moving back bits bar and spring is convenient in the setting of Access Division.Spring consider the mode that bar adopts clamping with moving back, and in normal operation, moves back bits bar and can't be subject to outside pulling force, although therefore spring and move back consider bar to be worth doing connection very simply, also can not come off.
Described spring is the structure that top bore is large, bottom bore is little.Spring adopts up big and down small structure, and side is convenient to and is moved back the clamping of considering bar to be worth doing, and the spring be second arranged in aperture is not easy therefrom to come off.
The described bottom surface of moving back bits bar does not exceed the inclined plane that cutter body its lower edge is formed.Move back bits bar in the process of cutter body incision, at paper chip not to when moving back bits bar force, moving back bits bar can not initiatively exert a force to paper.
The diameter of described notch is greater than the diameter of described macropore.The diameter of notch is greater than the diameter of macropore, is convenient to the activity of moving back bits bar.
The lateral surface of described cutter body is provided with annular groove, and described annular groove is positioned at the top of shoulder hole.Annular groove is generally positioned at the middle part of cutter body, is convenient to the installation of cutter body, is also positioned at the top of shoulder hole simultaneously, is independent of each other with shoulder hole.
The lateral surface of described cutter body is provided with cross-drilled hole, and described cross-drilled hole runs through cutter body and is positioned at the top of shoulder hole.Cross-drilled hole is generally positioned at the middle part of cutter body, is convenient to the installation of cutter body, is also positioned at the top of shoulder hole simultaneously, is independent of each other with shoulder hole.
Compared with prior art, the utility model has the advantage of that the notch bottom surface of cutter body lower end is provided with shoulder hole, spring and move back bits hole be arranged in shoulder hole.The diameter moving back bits bar is greater than hole diameter and is less than diameter macropores, and therefore moving back bits bar can only be movable in macropore, can not enter in aperture.The range of movement moving back bits hole is limited, and the decrement of effective control spring, can not excess compression, effectively can improve the service life of spring.Cutter body adopts cylindrical structure, and cylinder type different from the past, no matter be cut groove at the outer surface of cutter body, or punches at the outer surface of cutter body, all can not affect the structural strength of its entirety, can the various puncher of simple fit.
