Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, and more specifically, to a wrench for automobile repair that is convenient to adjust. Background Art

[0002] The wrench used for automobile repair is a tool specifically for automobile maintenance. It is usually used to tighten or remove bolts and nuts on automobiles. When performing automobile repair, sometimes it is necessary to remove and install bolts at some positions with relatively deep depths. Due to the narrow space where the bolts are located, it is very inconvenient to use an ordinary socket wrench for removal, and when using a T-shaped wrench, it is often difficult to remove because the length is not long enough. There is a technical problem that the length of the T-shaped wrench cannot be extended, which is not convenient for removing bolts at deeper positions.

[0003] After retrieval, a Chinese patent with the publication number CN215318357U discloses a wrench for automobile repair. By sliding the sliding rod, the distance between the connecting rod and the fixed rod can be adjusted, and thus the overall length of the fixed rod and the connecting rod becomes longer. During automobile maintenance, it is more convenient to extend into deeper positions to perform the operation of removing bolts, achieving the beneficial effect that the length can be adjusted to facilitate the removal of bolts at deeper positions.

[0004] During the use of the above wrench, the overall length of the fixed rod and the connecting rod can become longer, but it is not convenient to adjust the angle between the fixed rod and the connecting rod. The user directly places the hand on the connecting rod, and the wrist and forearm are interfered due to the limitation of the narrow space, affecting the naturalness and comfort of the operation.
