Description
Technical Field
The utility model relates to a wrench belongs to the assembly field.
Background
A wrench is a tool used to twist a workpiece and includes a handle and a working portion. In most environments, the handle can only be rotated through a small angle, and thus, the workpiece needs to be rotated continuously for many times to tighten or loosen the workpiece. The wrench needs to stop to rotate in the opposite direction for an angle between two rotations, and the normal way is that the wrench is held by the hand, the wrench is temporarily withdrawn from the workpiece and rotated in the opposite direction in advance, and then the wrench is placed on the workpiece again to continue the operation, and the advantage also needs to be assisted by the other hand. Obviously, the operation is inconvenient and affects the working efficiency.
A wrench with an operating handle can simplify this operation without having to remove the wrench from the workpiece and replace it on the workpiece between turns.
Disclosure of Invention
The utility model provides a wrench for realize many times continuous rotating work piece.
The technical scheme of the utility model is that: the utility model provides a wrench, includes body 1, first work portion 2, second work portion 3, body 1 has and can hold and cooperate first work portion 2, second work portion 3 to carry out cavity 4, cavity two 5 that move, first work portion 2 has the space with the work piece adaptation, makes third work portion 3 and first work portion 2 contact or break away from through the 3 motion of third work portion.
The first working part 2 is a hollow cylinder, the interior of the first working part is a hole matched with a workpiece, and the outer surface of the first working part is a semi-cylindrical groove matched with the second working part 3.
The second working part 3 is composed of three cylinders, and specifically comprises: one ends of the first cylinder and the second cylinder are connected, and a third cylinder 6 perpendicular to the two cylinders is connected at the joint of the two cylinders.
The utility model has the advantages that: the utility model realizes that the workpiece can be continuously rotated for many times without moving the wrench away from the workpiece and putting the wrench on the workpiece again by arranging the two working parts to be matched with each other, thereby improving the working efficiency of rotating the workpiece by using the wrench; and the utility model discloses simple structure easily makes and the cost of manufacture is low.

Detailed Description
Example 1: as shown in fig. 1-7, a wrench comprises a body 1, a first working portion 2, and a second working portion 3, wherein the body 1 has a first cavity 4 and a second cavity 5 which can accommodate and cooperate with the first working portion 2 and the second working portion 3 to move, the first working portion 2 has a space adapted to a workpiece, and the third working portion 3 is moved to contact with or separate from the first working portion 2 by the third working portion 3. The second working part 3 can be fixed in the body 1 through the second cavity 5, the second working part 3 can rotate relatively in the cavity of the body, and whether the first working part 2 rotates relatively to the body 1 can be controlled by operating the second working part 3 to tighten or separate from the body 1. The second cavity 5 is a cavity hollowed out of the main body 1 and capable of accommodating the second working part 3 and providing a sufficient moving space for the second working part 3; the cylindrical hole 7 belongs to one part of the second cavity 5, and the third cylinder 6 of the second working part 3 is clamped into the cylindrical hole 7 in the second cavity 5, so that the second working part 3 can rotate relatively in the cavity of the body through the third cylinder 6 which is in contact with the body 1. The first cavity 4 comprises a cylindrical round pipe wrapping the first working part, the radius of the hollow part in the first cavity is slightly larger than the outer diameter of the cylinder of the first working part, and the distance between the upper bottom surface and the lower bottom surface of the hollow part is equal to the distance between the upper bottom surface and the lower bottom surface of the first working part.
Further, the first working component 2 may be a hollow cylinder, the interior of the first working component is a hole matched with the workpiece, and the outer surface of the first working component is a semi-cylindrical groove capable of being matched with the second working portion 3, so that the second working portion 3 is in contact and matching with the cylindrical groove to form a clamping relationship.
Further, the second working portion 3 may be formed by three cylinders, specifically: one ends of the first cylinder and the second cylinder are connected, and a third cylinder 6 perpendicular to the two cylinders is connected at the joint of the two cylinders (one ends of the first cylinder and the second cylinder are connected to form an included angle, such as 100-110 degrees, the other end of the first cylinder is a free end and is used for holding, and the other end of the second cylinder is used for being matched with the first working part 2).
Further, the diameter of the workpiece to which the first working part 2 is applied may be set to 6 to 20 mm.
The utility model discloses a theory of operation is: the second working part can act through the extending part; when the wrench rotates along a first direction, the second working part 3 can be operated to enable the second working part 3 to contact the first working part 2, so that the first working part 2 abuts against the body 1, and the wrench and a workpiece arranged in a middle hole of the first working part 2 cannot rotate relatively; when the wrench rotates along a second direction opposite to the first direction, the workpiece is fixed, the second working part 3 is separated from the first working part 2 by operating the second working part 3, so that the wrench rotates relative to the workpiece, and the workpiece is rotated for multiple times continuously by repeated operation.
While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
