Description

A kind of convenient labour-saving spanner

Technical field

The utility model relates to spanner technical field, specially a kind of convenient labour-saving spanner.

Background technique

Spanner is a kind of common installation and removal tool, be twisted using lever principle bolt, screw, nut and other Screw thread tightly holds the opening of bolt or nut or the hand tools of trepanning firmware, and spanner is divided into two kinds substantially, solid wrench and adjustable wrench, Spanner usually uses the structure steel making of carbon or alloy material, spanner usually the one or both ends of shank be formed with grip bolt or The opening or sets of holes of nut, threadingly direction of rotation in shank applies external force when use, can twist bolt or nut, at present electricity Other have the spanner of liberation manpower many to wrench etc., but manual wrench is because of its unique advantage or critically important tool.It pulls Hand is a tool critically important in an important component and our daily production and living in hand-operated tools field. In daily life work, twists the connecting elements such as bolt, nut and screw and often need to use spanner.Such as assembly, processing and maintenance Product etc. just needs to use spanner.Serious consequence often is caused because some bolt is not tightened at present, but existing is pulled Hand leads to spiral shell because the screwing force that behaviour can be provided is not able to satisfy due to spanner tightens screwing force required for certain bolts or nut The problem of mother can not tighten.

The Anti-slip type tool changing spanner disclosed in 203266524 U of Chinese utility model patent ublic specification of application CN, The Anti-slip type tool changing spanner, although using anti-slip retainer ring and ratchet wheel locking device, ratchet wheel locking device can lock anti-skidding Dynamic rotation angle of the retainer ring relative to quiet retainer ring, keeps good coupling mechanism force, opposite without making to generate between cutter and spanner Slipping phenomenon, it is therefore prevented that the personal injury safety generated when skidding is changed to the fulcrum with wrench body integral type split type Changeable type high rigidity pivot screw after, pivot screw damage after, do not need to scrap entire wrench body, only need Replace pivot screw, can continue to use, largely save resource, still, the Anti-slip type tool changing spanner, have because The screwing force that people can be provided is not able to satisfy spanner and tightens screwing force required for certain bolts or nut and cause nut can not The shortcomings that tightening.
