Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a spanner and a monkey wrench that applies a force only in one direction to rotate when fastening or unfastening a fastening part such as a hexagon head bolt or a hexagon nut.

[0002]

[Problems to be solved by conventional techniques and devices]

 Generally, spanners and monkey spanners are used when tightening and unfastening fastening parts such as hexagon head bolts and hexagon nuts. However, conventional spanners and monkey spanners have a fixed clamping groove standard.Therefore, when tightening components are to be clamped in the clamping groove and then rotated, they must be rotated by a fixed rotation angle and then re-clamped. It has to be done, and there is a drawback that the work is inconvenient and the operation is slow.

Therefore, the present invention has been studied in order to solve such a conventional inconvenience, and it is possible to achieve the object only by sandwiching the fastening component in the clamping groove and repeatedly rotating it in one direction. The object of the present invention is to provide a spanner or a monkey spanner that can be conveniently used by specifically configuring the holding groove in the.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is a spanner or a monkey spanner having a holding portion for holding a tightening component such as a nut, and is enlarged to one of the holding end surfaces of the holding portion facing each other. A spanner or monkey wrench having a structure in which a groove is formed and a short clamping end surface for clamping a part of the side surface of the tightening component is formed between the enlarged groove and the bottom surface of the clamping groove. Is. This wrench or monkey wrench allows the fastening component to be sandwiched between the sandwiching end faces on both sides when the fastening component is sandwiched in the sandwiching groove.Therefore, force is applied when rotating in the direction from the enlarged groove to the opposing sandwiching end face. When rotating in the opposite direction, the corners of the fastening component are put into the enlarged groove and the spanner idles.

A spanner or monkey spanner having a holding portion for holding a tightening component such as a nut, wherein an enlarged groove is recessed in an intermediate portion of one of the holding end surfaces of the holding portion. A short clamping end surface that clamps a part of the side surface of the fastening component between the enlarged groove and the bottom surface of the clamping groove, and the two parallel sides of the fastening component are separated from the short clamping end surface. It is set so that the clamping groove opening side portion and the clamping groove opening side corner portion of the side surface of the tightening component that is clamped by the clamping end surface facing each other and is in contact with the short clamping end surface are located in the enlarged groove portion. A spanner or a monkey spanner can be provided with a structure.

[0006]

[Embodiment of the invention]

 A preferred embodiment of a spanner and a monkey spanner according to the present invention will be described in detail with reference to the drawings.

1 to 4 are diagrams showing the configurations of a spanner and a monkey spanner according to the present invention. That is, the wrench of the present invention, as shown in FIGS. 1 and 2, is provided with a holding groove 4 in which the holding end faces 201 and 205 are formed opposite to each other on the holding portion 2 formed at the end of the handle 1 so that one end is opened. An enlarging groove 203 is formed in the middle of one of the clamping end faces 201, and a short clamping end face 202 is formed between the enlarging groove 203 and the clamping groove bottom face 204. The hexagon nut (hexagonal bolt head) 6 When the portion 601 is brought into contact with the bottom surface 204 of the holding groove and the two parallel side surfaces 602, 602 of the hexagonal nut 6 are held by the holding end surfaces 202 and 205, the same portion as the opening side of the holding groove of the side surface 602 that contacts the holding end surface 202 is formed. The side surface corner portion 601 is set to be located in the enlarged groove 203 portion. Therefore, this spanner can grab a fastening component such as a nut (hexagonal bolt head) 6 and turn the handle 1 in a direction from the enlarged groove 203 toward the sandwiching end surface 205 without the enlarged groove 203, which rotates the nut 6. Is configured.

In addition, as shown in FIGS. 3 and 4, the monkey spanner slides the movable holding portion 3 on one side of the cantilever-shaped holding portion 2 formed at the end of the handle 1 by the drive screw 5. It is installed as much as possible, and the holding groove 4 is configured to be expandable / contractible. Similarly to the above, an enlarged groove 203 is formed in the middle portion of the holding end surface 201 of the holding portion 2 fixed, and a holding end surface 202 is formed inside thereof. The short clamping end face 202, the clamping groove bottom face 204, and the clamping end face 301 of the movable clamping unit 3 are configured to be able to clamp and rotate a fastening component such as a hexagon nut or a hexagon bolt head.

In the spanner of the present invention configured as described above, when the hexagonal nut 6 or the like is inserted into the holding groove 4 and the side corner portion 601 of the nut 6 is brought into contact with the center of the holding groove bottom surface 204, As shown in FIG. 2, since the two side surfaces 602, 602 of the hexagonal nut 6 are sandwiched by the sandwiching end surface 205 and the sandwiching end surface 202, a clockwise direction a (direction from the sandwiching end surface 202 to the sandwiching end surface 205 without the expansion groove 203). When rotating the wrench, the force can be applied to the hexagonal nut 6, but when rotating it in the opposite direction b, the side corner 601 of the hexagonal nut 6 on the tip side of the clamping end face 201 is inserted into the enlarged groove 203. After the spanner rotates idly, the short holding end surface 202 comes into contact with the adjacent side surface 602 of the hexagon nut 6, so if the spanner is rotated clockwise, the nut continues to rotate. 6 can be rotated.

In the case of a monkey wrench, if the hexagonal nut 6 is inserted into the variable holding groove 4 and the holding interval is adjusted so that the corner portion 601 of the nut 6 abuts the center of the holding groove bottom surface 204. As shown in FIG. 4, when the two side surfaces 602, 602 of the nut 6 come into contact with the holding end surface 301 of the movable holding portion 3 and the holding end surface 202 of the fixed holding portion 2, the hexagonal nut 6 comes to be held. 6 can be continuously rotated in the clockwise direction a, and when it is rotated in the opposite direction b, the corner 601 on the tip side of the hexagon nut 6 is inserted into the enlarged groove 203 and the monkey spanner rotates idly, and the spanner of the spanner is rotated. Similarly to the case, the nut 6 can be continuously rotated.

Therefore, with the hexagon nut 6 still inserted in the holding groove 4, the holding groove 205 is held by the holding end surface 205 (in the case of a monkey spanner, the holding end surface 301 of the movable holding portion 3 is not formed). ) Can be tightened by applying a force to the nut 6 only when the wrench (monkey wrench) is turned, and when it is desired to unfasten the nut 6, turn the holding part 2 over and turn the nut 6 The hexagon nut 6 can be unwound by pinching and rotating.

As described above, if there is a wrench or monkey wrench of the present invention, the nut can be tightened or unfastened by sequentially pressing and rotating in one direction without sandwiching the nut in the holding groove and removing it. Therefore, the work becomes quick and easy. In addition, a new spanner with excellent use effect can be made with a very simple change such as forming an enlarged groove in the fixed holding part, so the present invention is convenient to manufacture, does not require a large production cost, and is practical. And there is an advantage that you can make highly economical products.
