Description

Double force oblique cutting pliers structure

The invention relates to the technical field of a double force clamp, in particular to a double force oblique shearing jaw structure with a cutting edge.

For the structure of the tool pliers, reference may be made to the tool pliers structure of the Chinese Patent Publication No. M321834, which is mainly formed by two pliers having opposite shapes in a proper position, and the two connecting pieces are pivotally connected to each other. The shank of the tong handle forms a grip section and a clamping section with a shearing function on both sides of the pivot of the connecting piece.

The tool tong structure of the conventional publication No. M321834 has the same gripping section and clamping section as a horizontal plane. Therefore, if the workpiece to be cut is adjacent to a working plane, the tool tongs need to be fitted to the working plane, resulting in a work plane. The user's exertion and operation troubles, therefore, how to be able to work with the work plane without disturbing the user's action, has been the focus of the industry.

It can be seen from the above-mentioned conventional double force tool pliers structure that compared with the general shearing pliers, there is no common central pivot design, but at both ends of the clamping section, the connecting pieces are pivotally connected to achieve mutual restraint, so when When the grip section moves relative to each other, the pivotal joints at the two ends of the pivoting piece will have a slight front and rear offset. Therefore, if the cutting edge and the clamping section are in a horizontal straight line, at most, only the edge of the cutting edge will be caused. Offset, but the cutting function of the cutting edge is still there, but if the blade is designed as a slanting opening in response to the above missing, Because the cutting edge deviates from this horizontal straight line (front and rear displacement), it will cause the cutting edge to be misaligned, resulting in the failure of the double force cutting pliers.

Therefore, in order to solve the need for the edge fit surface, and to avoid the lack of edge misalignment, the industry has proposed a solution, such as China Patent Bulletin No. I419771, which discloses the handle segment relative to the clamp. The segment bending is at a predetermined angle, so when the clamping segment is attached to the working plane, the grip segment is kept at a predetermined distance from the working plane, thereby avoiding the user being restricted by the working plane and overcoming the operation trouble. .

However, the structure of the conventional publication No. I419771 is still to keep the cutting edge in a horizontal straight line, but to achieve the purpose of moving away from the working plane by bending the grip segment, but this structure will infer other defects, for example; The technical means of bending the grip section will result in the loss of the overall strength of the tool pliers. Moreover, the conventional I419771 grip section has an angle with respect to the clamping section, and when the user shifts to the clamping section after the grip section is applied, the component of the force is caused, which causes the power output of the user to be degraded.

In addition, whether it is the prior case such as the publication No. I419771 or the announcement No. M321834, the cutting edges are horizontally straight with the clamping section, so when the workpiece is clamped, the working object is moved due to the shearing force. The displacement causes the user to work harder to complete the cutting of the work object, resulting in considerable inconvenience and trouble in use.

In view of the above problems and deficiencies of the prior art, it is an object of the present invention to provide a double-strength oblique-cutting pliers structure by using a beveled edge The shape is set, and it is different from the shape of the horizontal straight line of the conventional cutting edge, so as to overcome many shortcomings such as the prior case.

According to the above object of the present invention, there is provided a double-acting oblique-cutting forceps structure, which mainly comprises a first clamping handle and a second clamping handle which are symmetrical and intersect each other, so that the first and second clamping handles extend along the extending direction The two ends respectively form a grip segment and a clamping segment, and the two connecting pieces and the pivot shaft are matched in the clamping section, so that the clamping sections are integrally pivotally connected to each other, and the clamping sections of the clamping sections are symmetrically arranged with each other. Matching each other, assisting the connecting piece (two pivot points) to constrain one of the first and second shank movement trajectory limit columns and a chute to limit the displacement path of the clamping section, and the clamping section is provided with clamping The jaw portion of the workpiece is ground to form a set of symmetrical edge edges according to the need of cutting and the inner edge of the jaw portion, wherein each edge of the cutting edge has a predetermined oblique angle with respect to the extending direction of the first and second shanks . According to the structure as described above, the first and second shanks are in a straight line, except that the structural strength can be ensured, and the user's force can be directly reflected, there is no loss of component force, and the edge of the cutting edge has a predetermined slope. Cooperate, it can be used to fit the working surface, avoiding the restricted working surface, and avoiding the slippage of the working objects when cutting.
