Description

A kind of modified adjustable self-locking class ratchet spanner

Technical field

The invention belongs to hardware tool fields, are related to a kind of adjustable spanner, specially a kind of modified adjustable self-locking class spine Wheel spanner.

Background technology

Spanner is a kind of common installation and extracting tool.Bolt, screw, nut and other spiral shells are twisted using lever principle Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually formed with clamp holder in the one or both ends of shank Portion applies external force shank and applies external force, and the opening or sets of holes of bolt or nut are held with regard to that can twist bolt or nut.Along spiral shell during use Line direction of rotation applies external force in shank, with regard to that can twist bolt or nut.

Existing spanner be divided into it is fixed and two kinds movable, fixed spanner can only be directed to fixed nominal diameter make With and cannot being rotated backward during use, adjustment spanner rotational angle is again after needing to exit the fastener of effect It is caught in；It is thus desirable to the spanner of multiple and different models is equipped with, and use is also inconvenient.

Movable spanner is divided into two kinds：One kind is that spanner tooth is adjustable, can adapt to different shaped in a certain range Number fastener；Another kind is that rotation direction can be adjusted, and in the process of work, is rotated forward again after can be reversed idle running Firmly, it is represented as ratchet spanner；But this ratchet spanner is all certain fixing model size, structure is complete set cast Formula；It is used in a spanner currently without method by the effect of two kinds of monkey wrenches is several.The prior art exists about spanner Many places to be modified.

Utility model content

The purpose of this utility model be in view of the above problems, provide a kind of modified adjustable self-locking class ratchet spanner, can be compared with Fastener in a wide range of endoadaptation different model specification limit uses, adjust automatically locking, without manually adjusting, while groove As guide rail, it can further strengthen the service life of resetting-mechanism, it is simple and practical in structure convenient.

In order to achieve the above object, the technical solution adopted in the utility model is：A kind of modified adjustable self-locking class ratchet wrench Hand is hooked including holding rod and spanner, and one end of the holding rod is ratchet head, and the ratchet head is half arcuate structure, the ratchet Head is hinged with latch nook with holding rod junction by rivet, and polygon half coil structures to connect are set as on the inside of latch nook；It is described Half arcuate structure is oppositely arranged with half coil structures；Arc-shaped structure, the latch nook outside are set as on the outside of latch nook With a circular groove, the groove is matched with arc-shaped structure；Resetting-mechanism is further included, the resetting-mechanism includes insertion Spring in holding rod, the spring one end abut the holding rod other end and are arranged with movable loop bar, the other end of the activity loop bar Sliding equipment is provided with, the sliding equipment is slidably connected in circular groove.

Further, the sliding equipment includes connecting rod and pulley, and the connecting rod is fixed with the movable loop bar to be connected It connects, the pulley is arranged on the both ends of connecting rod, and the pulley is abutted with the circular groove.

Further, taper knob is also cased on the holding rod, the taper knob outer surface sets several anti-slop serrations.

As an improvement in the spring setting and the taper knob, the taper knob has the blind hole for placing spring, One end of the activity loop bar is located in the blind hole, the activity loop bar and the blind hole clearance fit.

Specifically, the arc-shaped outside of the driving end is provided with tooth-shape structure.

Further, the both ends of the holding rod are both provided with ratchet head and latch nook.

The beneficial effects of the utility model：The utility model provides a kind of modified adjustable self-locking class ratchet spanner, leads to Cross setting resetting-mechanism so that the fastener in ratchet spanner energy wide range endoadaptation different model specification limit uses, from Dynamic adjustment locking without manually adjusting, rotates forward firmly, structure letter again after having the reversed idle running of the effect of ratchet spanner offer Single practical convenient.Groove can further strengthen the service life of resetting-mechanism as guide rail simultaneously.
