Description

  The present invention relates to a stopper part to be mounted on a long pattern type vertical working tool such as a trimming shear or a pruning shear.

  The vertical work tool crosses two members, pivots the intersecting portion, uses one as a handle portion, and the other as a working portion of a cutting blade body or a sandwiching body.

  In such a working tool, as shown in FIG. 1 of Patent Document 1 (Japanese Utility Model Publication No. 1-25566), the left and right hands holding the handle when the handle is closed are mutually connected. A stopper is provided so that it does not collide, or when the action part is closed, the jaws of the front and back members at the overlapping part in the vicinity of the pivoting part come into contact (collision) to act as a stopper, and the handle part has a predetermined interval Like to maintain.

  Some work tools provided with a cutting action part are provided with ridges that are biased in the opening direction so as to be convenient for continuous cutting. As a starting point, a spiral spring (Patent Document 2: Japanese Utility Model Publication No. 58-158666), a leaf spring (Patent Document 3: Japanese Utility Model Publication No. 60-12483), a coil spring (Patent Document 4: Japanese Utility Model Application Publication No. 60-72149). Publication) etc. are adopted.

  However, as described in Patent Document 1, the work tool that has a long handle and is operated with both hands adopts a structure that exerts a stopper action so that the left and right handle portions have a predetermined interval during cutting operation and clamping operation. However, the impact of the collision of the stopper acts directly on the hand during cutting operation and clamping operation. In particular, during continuous cutting operation, the impact is continuous, and the impact on the hand can be reduced by operating so that the stopper portion does not collide, but the cutting efficiency is poor and it is not necessarily an easy-to-use tool.

  Further, in a work tool provided with a ridge that biases in the opening direction, movement in the opening direction after the cutting operation is easy to operate in the opening direction due to the urging force of the ridge, but in the operation in the cutting direction, In the saddle type work tool having a long handle, it is not recognized that the insertion of the striation between the handle portions necessarily improves the operability.

  Therefore, the applicant of the present application is a part that collides because the rotation about the pivot axis stops when the action part is fully closed, for example, a protrusion provided on the opposite surface of the handle part, or the vicinity of the pivot point. The tool which provided the elastic part provided with the appropriate cushion function and the repulsion function in the site | part which becomes a member collision location in the member superposition | polymerization location of this was proposed (patent documents 5, 6).

FIG. 1 of Japanese Utility Model Publication No. 1-2556. Japanese Utility Model Publication No. 58-158666. Japanese Utility Model Publication No. 60-12483. Japanese Utility Model Publication No. 60-72149. Registered utility model 3131224. Registered utility model 3123343 gazette.

  The collision part (stopper part) in the handle described above is provided with a cushion function and a repulsion function so as to absorb a shock caused by the collision of the collision part when holding the handle part and performing a predetermined opening / closing operation. At the same time, the repulsive force of the elastic portion becomes an urging force in the opening direction, and the opening / closing operability is improved. However, since the above-described work tool is configured to incorporate the stopper portion directly into the handle, a dedicated handle structure including the stopper portion must be employed in advance.

  Therefore, the present invention proposes a stopper part for a vertical work tool having versatility as a part with respect to a pipe handle or a round bar-like wooden handle frequently used in existing work tools.

  The stopper part for a vertical working tool according to the present invention is the above-mentioned handle in the tool body in which two members are crossed and the intersection is pivoted so that one is used as a handle insertion part and the other is used as an action part of a cutting blade body or a sandwiching body. A part used for a vertical work tool formed by attaching an insertion part to a handle such as a pipe handle or a round bar-like wooden handle, and a handle-attaching tubular part that is tightly inserted and fixed to the tip of the handle body, and A handle mounting body provided with a holding cylinder portion protruding from the outer peripheral surface of the handle mounting cylindrical portion, a compression ridge mounted in the holding cylinder portion, and fitted into the holding cylinder portion in a protruding state by the compression ridge. It is comprised by the stopper body provided with the insertion cylinder part and the collision surface part provided in the insertion cylinder part front-end | tip.

  Therefore, when the handle mounting body is tightly inserted and fixed to each tip portion of the pair of handle bodies, the striation and the stopper body are incorporated into the holding cylinder portion of the handle mounting body, and the handle insertion portion of the tool body is connected to the handle body as usual. A work tool incorporating the parts of the present invention is formed. This work tool grips the handle and causes the action part to perform a predetermined work (cutting or clamping) by opening and closing the handle, operating the handle in the closing direction, and when the collision surface parts collide with each other, The impact of the collision is absorbed by the elasticity of the compression ridge, and the handle is urged in the opening direction by the repulsive force of the compression ridge after the collision, so that the opening direction operation is smoothly performed.

  As described above, the present invention can be applied to a tool having a pipe handle or a round bar-like wooden handle, which is frequently used for existing work tools, by simply attaching a stopper part, without being shocked by the hand, The repulsive force allows continuous operation to be performed rhythmically.
