Abstract
The utility model provides a limiting structure of gear engagement linkage scissors. The limiting structure comprises a main tool body, a secondary tool body, a force application handle, a limiting sheet and a plurality of pivoting pieces, wherein the main tool body is provided with a main pivoting hole and a secondary pivoting hole in a central passing manner; the main pivoting hole and the secondary pivoting hole are respectively pivoted with the secondary tool body and the force application handle; a linkage gear part and an actuation gear part which are engaged with each other are arranged at the inner sides of the secondary tool body and the force application handle in an extending manner; and the limiting sheet is adhered beside the secondary tool body and the force application handle, so as to be pivoted through the pivoting pieces. With the adoption of the structure, the limiting sheet is clamped with the secondary tool body and the force application handle through bolts and screws of the pivoting pieces, so as to limit axial positions of the linkage gear part and the actuation gear part. Therefore, the secondary tool body is prevented from torque influence of shearing force, so that the product durability is enhanced by reducing the engagement precision of the linkage gear part and the actuation gear part.
Description
Technical field
The utility model is relevant for a kind of " position limiting structure that tooth interlock interlock is cut "; Especially refer to that banking stop sees through the bolt and the nut of pivot knot part; Formation is established the folder of secondary cutter hub and effort handle, and is able to limit the axial location of interlock tooth portion and start tooth portion, receives the torque influence of shearing force in order to avoid secondary cutter hub; And reduce the meshing precision of interlock tooth portion and start tooth portion, reach the function of promoting the product durability.
Background technology
Existing a kind of clipper structure, many shown in Figure 13 and Figure 14, it comprises a main body of shearing tool 70, a cutter 80 and an effort handle 90; Wherein, main body of shearing tool 70 is provided with a pulley base 71 in the below, and cooperation is provided with a tool rest 72 in pulley base 71 tops; This tool rest 72 runs through in central authorities and is provided with the hole 73 that is pivoted, and by be pivoted hole 73 to a side be extended with one be the curved arc shape cultellus portion 74, opposite side is provided with a driven tooth portion 75; Be connected to an elastic component 76 in tool rest 72 upper set again, cutter 80 is provided with an axis hole 81 in central authorities, thus with the hole 73 pivot group mutually that is pivoted of main body of shearing tool 70; And extend to two ends by axis hole 81 and to be formed with a blade 82 and a linking arm 83 respectively, this linking arm 83 is provided with a pivot hole 84 in the adjacent end place, and effort handle 90 is provided with a driving gear portion 91 in an end; This driving gear portion 91 is mutually meshing with the driven tooth portion 75 of main body of shearing tool 70; And be provided with a pivoted hole 92 in contiguous driving gear portion 91 places, with the pivot hole 84 of cutter 80 pivot group mutually, the other end in effort handle 90 is provided with a joint portion 93 more thus; These 93 inboards, joint portion are connected with the elastic component 76 of main body of shearing tool 70; The outside then is pivoted with an assembly pulley 94, and 71 of pulley bases of this assembly pulley 94 and main body of shearing tool 70 and tying up are wound with one and supply to draw the stay cord 95 of use of pulling, and make cutter 80 receive stay cord 95 and elastic component 76 to reach the continuous start of shearing.
The above-mentioned existing structure of detailed sight is not difficult to realize its shortcoming part; Main cause is summarized as follows: when cutter 80 bears shearing resistance; Its effort handle 90 will bear huge moment of torsion with the meshing place of main body of shearing tool 70; This will make the driving gear portion 91 of effort handle 90 be easy to generate radial deflection and misplace, and cause effort handle 90 to fail positively meshing transmission, and then be formed with the not enough disappearance of product practicality.
In view of this, the creator originally is engaged in the manufacturing development and the design experiences of Related product for many years, to above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.
The utility model content
