Technical field
The present invention relates to a kind of spanner, especially a kind of special spanner of four slot stripped nuts.
Background technique
Four slot locking nuts and bolt or screw rod are threaded together and play fastening effect to part.Currently, in maintenance of equipment mistake
Selenodont spanner is usually used in Cheng Zhong, fastening and four slot locking nuts of release, and the hook of crescent wrenches one end catches on four slots
One slot of locking nut tightens or loosens four slot locking nuts by rotation；This spanner stability is poor, fastening
Or unclamp nut and need biggish torque in the process, it is easy to slip out of the hand, may cause certain injury to maintenance personal；Also, one
The selenodont spanner of kind model generally only corresponds to a kind of four slot locking nuts of model, and manufacturing cost is higher；When four slot locks are tight
Near nut can operating space it is smaller when, can not just use crescent wrenches.When fastening and unclamping four slot locking nuts, have
When also use hammer and blunderbuss to carry out compounding practice, but this method, because firmly excessive, impact force is very big, it is easy to damage four slots
Locking nut, and people is easily damaged when blunderbuss is beated.
Summary of the invention
To solve the technical problem in above-mentioned background technique, the present invention provides a kind of Special pulls of four slot locking nuts
Hand, which can fasten and unclamp four slot stripped nuts of different-diameter, time saving and energy saving, simple and convenient, improve
Maintenance efficiency and safety.
Specifically, the special spanner of four slots stripped nut of the present invention, with wrench body, tooth and positioning
Bolt；The wrench body leading portion is in cylindrical, is opened up respectively along the two perpendicular diameter direction of front end face there are four deep trouth, institute
The bottom for stating deep trouth offers threaded hole；The body shape of the tooth and the shape of deep trouth are adapted, and the leading portion of tooth has protrusion
The screw hole shape of portion, the shape of the protrusion and four slot locking nuts is adapted；And screw hole is offered in the main body of tooth, the screw hole
Position and deep trouth bottom screw thread hole site be adapted；The positioning bolt is each passed through screw hole and threaded hole, and by tooth with
Main body is fastenedly connected by positioning bolt.Using effect while four slots and tooth being correspondingly arranged with nut, four can be made
The elastic operation of slot locking nut is more stable, and will not damage to nut main body.
In the present embodiment, in four deep trouths, shallow slot is offered respectively between each adjacent two deep trouth, and the shallow slot is deep
Degree is less than the depth of deep trouth, and the shape of shallow slot shape and deep trouth and tooth is adapted；The bottom of the shallow slot offers threaded hole.
There is other slot by the way that the depth is arranged, the spanner can be made to be suitable for the nut of a variety of different-diameter sizes, improved of the present invention
The scope of application of spanner.
In the present embodiment, also there is gasket, which is adapted with tooth body shape, and pads to have set on tooth and determine
Position bolt on side；Connecting hole is offered on the gasket, screwhole position is adapted on the position of connecting hole and tooth.By adding
Gasket is filled, the height of each tooth is finely adjusted, active position can be more accurately fitted in, promotes spanner of the present invention
Practicability.
In the present embodiment, gasket with a thickness of 2mm, 2.5mm or 3mm.
In the present embodiment, the threaded hole on deep trouth is through-hole, and the threaded hole on shallow slot is blind hole.
In the present embodiment, the hole on the gasket is counterbore, increases the stability in use of gasket construction with this.
In the present embodiment, the rear end of wrench body is provided with extension bar, promotes the active force to nut with this, further
Improve the practicability of spanner of the present invention.
