1. Ratchet wrench
A ratchet wrench belongs to the technical field of wrench tools. The ratchet wrench includes a wrench main body, and the accommodating space of the head of the wrench main body is matched with a circlip, a pawl, a spring and a ratchet wheel, wherein the ratchet wheel is composed of a ratchet wheel main body and a spacer, the spacer sleeve. It is a circular ring with a concave ring groove on the periphery, and the spacer sleeve is fitted on one side of the ratchet main body.
2, dumb wrench
A dead wrench, also known as an open-ended wrench (or a dead wrench), is mainly divided into a double-ended dead wrench and a single-ended dead wrench. One or both ends of the wrench are provided with an opening of a fixed size, and the size of the opening is adapted to the size of the screw head and the nut, and is made according to the standard size. It has a wide range of functions, mainly in the fields of mechanical maintenance, equipment installation, home decoration, and auto repair.
3. Torx wrench
The two ends of the plum wrench are garlands, and the inner hole is formed by two regular hexagons staggered concentrically by 30°. Many Torx wrenches have elbows, and the common elbow angle is between 10° and 45°. From the side, the rotating bolt part and the handle part are staggered. This structure is convenient for dismantling the bolts and nuts assembled in the concave space, and can provide operating clearance for fingers to prevent scratches. Used in supplementary tightening and similar operations, a Torx wrench can be used to apply high torque to a bolt or nut.
