Problems solved by technology

[0004] However, it is not easy to combine ratchet and adjustable functions in one wrench, which will lead to a relatively complicated structure, making tool production difficult and costly, and in addition, when the torque is large, the wrench will be damaged

Embodiment 1

[0048] Such as figure 1 and figure 2 As shown, the wrench includes a body 11 and a first working part 12 extending along one end of the body 11. The first working part 12 has a first accommodating space 18 for accommodating and matching the workpiece. The body 11 also functions as a handle. Since the size of the main body 11 will affect the size of the output force, the diameter range of the workpiece that the wrench is suitable for, and the stability during use, etc., on the basis that the size of the main body 11 is suitable for the user to hold, it can be adjusted according to the needs. Change the size of the main body 11 accordingly.

[0049] The first working part 12 is fixedly connected with the main body 11 , and can also be integrally formed with the main body 11 . In this embodiment, the first working part 12 and the main body 11 are designed to be integrally formed.

[0050] The main body 11 and the first working part 12 can be made of cast steel or other high-st...

Embodiment 2

[0075] The overall structure of the wrench in the second embodiment is similar to the wrench in the first embodiment, the main difference is that the structure for realizing the rotary function is different.

[0076] Such as Figure 12-Figure 14 As shown, the wrench in this embodiment includes a main body 11 and a first working part 12 extending along one end of the main body 11. The first working part 12 has a first accommodation space 18 for accommodating and matching the workpiece. The main body 11 also Acts as a handle. Since the size of the main body 11 will affect the size of the output force, the diameter range of the workpiece that the wrench is suitable for, and the stability during use, etc., on the basis that the size of the main body 11 is suitable for the user to hold, it can be adjusted according to the needs. Change the size of the main body 11 accordingly.

[0077] The first working part 12 is fixedly connected with the main body 11 , and can also be integral...

Embodiment 3

[0096] Embodiment 3 is actually a combination of Embodiment 1 and Embodiment 2. In Embodiment 3, the first working part 12 and the first component 21 adopt the structure of Embodiment 1, while the second working part 13 and the second component 22 adopt the structure of Embodiment 2. The other structures of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a spanner. The spanner comprises a body and a first working part stretching along one end of the body. The first working part is provided with a first containing space capable of being matched with a workpiece. The first working part is further provided with a first pawl assembly. The first pawl assembly is arranged to be in the state that when the spanner rotates in the first direction, the spanner does not rotate relative to the workpiece; and when the spanner rotates in the second direction opposite to the first direction, the workpiece is fixed, and the spanner rotates relative to the workpiece. According to the spanner, the workpiece is continuously rotated multiple times, the spanner does not need to be moved away from the workpiece and arranged on the workpiece again, and therefore the working efficiency of the spanner is improved. In addition, the spanner is simple in structure, and large torque can be borne; and meanwhile, manufacturing procedures are simple, and the manufacturing cost is low.

Description

technical field [0001] The present invention relates to a hand tool, and more particularly, to a wrench. Background technique [0002] A wrench is a tool used to twist a workpiece, including a handle and a working part. In most usage environments, the handle can only be rotated at a small angle, so the workpiece needs to be rotated several times in a row to tighten or loosen the workpiece. Between two rotations, it is necessary to stop and allow the wrench to turn an angle in the opposite direction. The usual practice is to temporarily withdraw the wrench from the workpiece to realize the reverse rotation, and then put it back on the workpiece to continue the operation. Sometimes it is necessary to use The other hand assists. Obviously, this operation is very inconvenient and affects work efficiency. [0003] A wrench with a ratchet feature simplifies this operation by eliminating the need to remove and reposition the wrench from the workpiece between turns. [0004] How...
