Description

A kind of All-in-One nut spanner

Technical field

The utility model relates to spanner technical field more particularly to a kind of All-in-One nut spanners.

Background technique

Ratchet spanner is a kind of manual screw tightening tool, and the more specification movable handle double offset ring spanner with ratchets of single head, double end are (fixed Hole), it is to be connected by way of the negative key of hinged key and positive key occlusion by the main plum blossom-like sheath of different specification size and from plum-blossom sleeve It connects, since a plum-blossom sleeve tool is there are two the quincunx through-hole of specification, it is made to can be used for the elastic of two kinds of specification screws, from And use scope is expanded, raw material and work time cost are saved, movable trigger piece adjusts spanner using angle in which can be convenient, and uses In the elastic operation of screw, there is the characteristics of strong applicability, easy to use and low cost；Patent Office of the People's Republic of China discloses a kind of commutation Ratchet spanner (publication number: CN2751974), the reversing groove including being provided with Wrench head Yu shank intersection, with reversing groove phase Pulling hole that is logical and penetrating spanner one side outward, the reversing machine of the ratchet block being accommodated in reversing groove and conflict on ratchet block Structure, it is characterised in that the reversing mechanism includes shifting block and driving lever, wherein shifting block a part is installed in pulling hole, a part dew Wrenching surface out, shifting block are installed with the part in pulling hole equipped with driving lever hole, and a part of driving lever is mounted in driving lever hole, driving lever Expose shifting block and contradict the part on ratchet block, end is the ball that can be rolled in ratchet block bottom；But this spanner It is only applicable to the nut of a specification, is not available the nut in other specifications, applicability is bad.

Utility model content

The utility model mainly solves the problems, such as of the existing technology, provides a kind of the more of the nut suitable for plurality of specifications Unify nut spanner.

Above technical problems of the utility model are mainly solved by the following technical scheme:

A kind of All-in-One nut spanner, including handle, handle one end are equipped with commutation ratchet device, the ratchet device packet Commutation button is included, commutation button has pawl by driving lever abutting, and pawl is engaged with ratchet ring, is equipped in ratchet ring inner hole radially movable C clamp pawl,

The utility model works after passing through C clamp pawl clamping screw nut, and C clamp pawl is radially movable, is adapted to not With the nut of size specification, adaptability is good.

Preferably, the ratchet ring external annulus is equipped with the ratchet part engaged with pawl, ratchet ring both ends are equipped with and C-shaped The radial channels of the mutually movable clamping of clamping jaw.

The moving direction of C clamp pawl is controlled by radial channels, simple and stable structure is less prone to failure.

Preferably, the C clamp pawl includes the perpendicular pawl in ratchet ring inner hole, with the mutually movable card of radial channels The upper horizontal pawl and lower horizontal pawl connect, is equipped in the C clamp pawl and perpendicular pawl elastomer block disposed in parallel, one end face of elastomer block abut Ratchet ring inner hole wall, one end face of elastomer block connect perpendicular pawl by several groups spring disposed in parallel.

Preferably, the upper horizontal pawl, perpendicular pawl and lower horizontal pawl are the integrated design, erect pawl lateral surface and be equipped with anti-skidding muscle Item, the connection dog-ear for erecting pawl lateral surface and upper horizontal pawl and lower horizontal pawl is fillet.

Integrated design structural strength height is hardly damaged, and anti-skidding rib reinforces the bonding strength with nut, prevents from skidding, even Connecing dog-ear is that fillet is convenient for being inserted in when starting attaching nut.

Preferably, the C clamp pawl is at least provided with three, adjacent C shaped clamping jaw spacing is equal.

The common clamping screw nut of C clamp pawl of three or more be arranged, stability is good, is less prone to showing for nut skidding As.

Preferably, the handle other end is connected with fork spanner or adjustable wrench or double offset ring spanner or double commutations Ratchet spanner.

The handle other end, which is equipped with different types of spanner, can increase the adaptation range of the utility model.

The utility model is simple and reasonable for structure, and suitable for the nut of different plurality of specifications, applicability is good.
