Description

Technical Field

[0001] The present application relates to the technical field of ratchet wrenches, and in particular to an anti-slip ratchet wrench. Background Art

[0002] The working end of a ratchet wrench is usually called a ratchet head or a ratchet working head. The structure of a ratchet wrench includes a ratchet head and a wrench body that matches the ratchet head. One end of the ratchet head has a wrench hole that matches a bolt or a nut.

[0003] The existing patent (publication number: CN217915045U) discloses an anti-slip joint ratchet wrench, including a ratchet wrench handle, a flip mechanism is provided at the top of the ratchet wrench handle, and a connecting rod is sleeved on the outside of the flip mechanism, a plate head is installed at the top of the connecting rod, and an anti-slip sleeve is sleeved on the bottom of the outside of the ratchet wrench handle, and protective grooves are evenly provided on the anti-slip sleeve. The utility model drives the worm to rotate by rotating the handle, and the worm and the worm wheel are meshed with each other, and then the worm wheel starts to rotate and drives the rotating shaft to rotate synchronously, that is, drives the connecting rod to do flipping movement, that is, adjusts the working angle of the connecting rod, can meet different use environments, and is more convenient to use. After the ratchet wrench is used, the connecting rod can be rotated to the hollow cavity provided inside the ratchet wrench handle, so that the ratchet wrench is easy to fold and the ratchet wrench is more convenient to carry.

[0004] The above-mentioned wrench can adjust the working angle of the connecting rod, which can meet different usage environments and is more convenient to use. However, when operating in some narrow spaces, there are great limitations. The connecting rod is long and difficult to operate. When used in some open spaces, it is not easy to extend the length of the connecting rod and it is relatively laborious. Secondly, the hand sweat will flow into the anti-slip sleeve from the sweat discharge hole and be absorbed by the moisture-absorbing cotton to prevent the accumulation of hand sweat and slipping, thereby improving the anti-slip performance of the ratchet wrench, making it difficult to clean. Some oil stains can easily enter the moisture-absorbing cotton and easily breed bacteria. Utility Model Content
