hand tools

This creative department is related to hand tools.

Hand tools are necessary tools for various operations. Their advantages are convenient to carry and good operability. There are many types of hand tools. According to the different driving objects, characteristics and uses, they can be divided into: pliers, wrenches, screwdrivers, sockets Class, scissors, cutting class, impact class, measurement class... etc. Among them, the wrench is the most common in daily life and processing factories. The common wrench is the handle in the middle, and the second opposite to the handle. At least one of the ends is provided with a driving part, such as an assembly hole and a clamping jaw, to connect the to-be-driven part.

However, the above-mentioned wrench is often limited by its length so that it cannot penetrate into a narrow space smoothly, and is usually limited by its linear structure, so when there are many obstacles in the working space or around the to-be-driven part , the user usually needs to adjust the posture of the arm to match, and the range of the angle that the arm can bend and swing is limited by the physiological structure, so it often happens that hand tools such as a wrench cannot be used to drive the to-be-driven piece.

Therefore, it is necessary to provide a novel and progressive hand tool to solve the above problems.

The main purpose of the present invention is to provide a hand tool, in which the first member and the second member can be relatively swingable selectively to meet the different needs of users, and at least one of the side walls of the two grooves of the positioning tooth groove for positioning is at least One of the two blocking walls is completely abutted with at least one of the two blocking walls in the positioning tooth slot, so as to generate more contact area and achieve the purpose of blocking and positioning.

In order to achieve the above object, the present invention provides a hand tool, which includes: a first member, a second member, a pivot and a control member. The pivot column defines a first end portion and a second end portion opposite along an axis direction, the first end portion is connected and positioned on the first member, and the second end portion is rotatably inserted and connected In the second member, a plurality of positioning tooth slots are recessed on the outer ring wall of the second end along the circumferential direction of the pivot column; the control member is arranged on the second member so as to be movable in a release position and a lock position, The control member includes at least one positioning tooth projection; wherein, when the control member is in the release position, the at least one positioning tooth projection is not inserted into the at least one positioning tooth slot, and the first member and the second member can pivot The column swings relative to the shaft. When the control member is in the locking position, the at least one positioning tooth protrusion is inserted into at least one of the positioning tooth grooves, and the first member cannot swing relative to the second member; wherein, each positioning tooth groove is located in the The pivot column defines two opposite side walls in the circumferential direction, and the at least one positioning tooth protrusion defines two opposite stop walls in the circumferential direction of the pivot column. When the at least one positioning tooth protrusion is inserted into the at least one positioning tooth slot, The part of at least one of the two blocking walls in the positioning tooth groove is completely abutted with at least one of the side walls of the two grooves.

The following examples only illustrate the possible implementation of this creation, but are not intended to limit the scope of protection of this creation. The “one” or “at least one” before the nouns mentioned in the text does not limit the quantity. According to the demand, there can also be "plurality", and the change in this number is also the scope of protection, which will be described first.
