Description

A kind of split type ratchet spanner

Technical field

The utility model relates to spanner technical field, specially a kind of split type ratchet spanner.

Background technique

Ratchet spanner is a kind of manual screw tightening tool, when the size of screw or nut is larger or the operating position of spanner It is very narrow, so that it may to use ratchet spanner, screw or nut can be tightened and be unclamped to the angle very little that this spanner is swung, by past Physical pendulum is started switching nut, convenient and efficient, laborsaving time saving, can carry out loose unloading and tight dress, and strong applicability is adjusted in which can be convenient It is whole to use angle, existing ratchet spanner using when the polygon inner hole sleeve of ratchet is mounted in the screw element that matches of geomery On, handle is moved in rotation, so that the screwing operations that unscrew of screw element are realized, when handle is moved in reverse rotation, due to screw element spiral shell The frictional force of line mating surface acts on so that ratchet have stagnate power to overcome between spring force and pawl and fixed block compared with Less friction, at this point, generating sliding between the gear teeth inclined-plane and pawl inclined-plane of ratchet, this course of work moves in circles and realizes spiral shell Line part screws unscrewing operation, and existing ratchet spanner is difficult to realize the assembly and disassembly operations to screw element.

Traditional ratchet spanner, most of is very simple device, it is difficult to the assembly and disassembly operations to screw element is realized, using model It encloses not wide enough, it is difficult to improve the assembly and disassembly efficiency of mechanical equipment, it is difficult to overcome and occur using tools such as common wrench and adjustable wrench Vulnerable to operating space limit to and lead to not using the drawbacks of, general ratchet spanner does not have Anti-slip cover, and stressed effect is bad And eely drawback, it improves spanner or is screwed the probability of part damage, reduce the operational safety of operator.
