It is right, coming off for spanner during locking nut is effectively avoided, operating efficiency is high, and improves the service life of spanner, reduces more
Change this into, stabilized structure is easy to operate, practical.
The technical solution adopted in the utility model is：
A kind of tetragonal nut special spanner, including left spanner and the handle being arranged on the right side of left spanner, left spanner and handle
It is integrally formed, rectangle sets of holes is offered on left spanner, four right angle turns of rectangle sets of holes is equipped with R angles；The handle
Tooth form anti-skid bulge is equipped with front end face and rear end face, and the thickness of handle is less than the thickness of left spanner.
Preferably, in addition to the right spanner of right handle is arranged on, right spanner is provided with the clamping part of opening to the right, and a left side is pulled
Head, handle and right spanner are integrally formed, and the thickness of right spanner is more than the thickness of handle.
Preferably, left spanner is circular spanner.
Preferably, tooth form anti-skid bulge is made up of rubber.
The utility model has advantages below：
（1）Using the R angles set by four right angle turns of rectangle sets of holes and rectangle sets of holes being arranged on left spanner, improve
The compatible degree of spanner and tetragonal nut, and the stress surface of spanner is added, coming off for spanner is not only effectively prevented, improve work
Make efficiency, and reduce abrasion of the tetragonal nut to spanner, substantially increase the service life of spanner, save replacement cost；
（2）Tooth form anti-skid bulge is equipped with the front end face and rear end face of the handle, improves the anti-skidding power of handle, in advance
The anti-industrial accident caused by spanner slides, has a safety feature；
（3）By the setting of right spanner, the scope of application of spanner is expanded, it is practical；
（4）Thickness more than handle is disposed as by the thickness of left spanner and right spanner, further improve left spanner and
The steadiness of right spanner structure, and then further improve service life of the present utility model；
（5）By the way that left spanner is set into circular, the anglec of rotation of the spanner in narrow space is improved, simple operation is real
It is strong with property.

Embodiment
The utility model includes left spanner 1, the handle 2 for being arranged on the right side of left spanner 1 and is arranged on the right side on the right side of handle 2 pulling
First 5, left spanner 1, handle 2 and right spanner 5 are integrally formed, and the thickness of left spanner 1 and right spanner 5 is all higher than the thickness of handle 2；It is left
Spanner 1 preferably uses circular spanner, and rectangle sets of holes 3 are offered on left spanner 1, and four right angle turns of rectangle sets of holes 3 are equal
Provided with R angles；Tooth form anti-skid bulge 4 is equipped with the front end face and rear end face of handle 2, tooth form anti-skid bulge 4 preferably uses rubber
It is made.
In order to more fully understand the utility model, the technical solution of the utility model is done furtherly presently in connection with accompanying drawing
It is bright.
As the first preferred embodiment, as shown in Fig. 2 the utility model includes left spanner 1 and handle 2；Pull on a left side
First 1 using rectangle spanner, i.e., the front end face and rear end face of left spanner 1 are rectangle, and four outside the left spanner 1 of rectangle are directly
There is smooth radian at angle, prevent sharp right-angle side from scratching operating personnel；Rectangle sets of holes 3, rectangle are offered on left spanner 1
Four right angle turns of sets of holes 3 are equipped with R angles, and the thickness of left spanner 1 is more than the thickness of handle 2；The front end face of handle 2 is with after
The anti-skid bulge 4 of tooth form is equipped with end face, in order to improve the comfort level of gripping handle 2, reduces wound of the anti-skid bulge 4 to hand
Evil, anti-skid bulge 4 are preferably made of rubber, and hand relaxes when gripping handle 2 can be improved while anti-skidding effect is ensured
Adaptive, reduce injury of the anti-skid bulge 4 to hand；Operating personnel, handle 2 are scratched in order to avoid the right-hand member of handle 2 is excessively sharp
Right-hand member can be set to round and smooth arc.
When using spanner, operating personnel hold handle 2, and the rectangle sets of holes 3 of left spanner 1 are set on tetragonal nut,
Then rotary handle 2 is fastened or dismantled to tetragonal nut.Four sides of left spanner 1 and tetragonal nut are fitted in one
Rise, and R angles and the radian of right-angle side outside tetragonal nut also fit together, and improve agreeing between spanner and tetragonal nut
Degree, effectively prevent spanner and comes off in use；Meanwhile good compactness also causes tetragonal nut to be not easy in rectangular sleeve
Skidded in hole 3, reduce the abrasion of left spanner 1, and then improve the service life of spanner, then coordinate the use of reinforcement 4, entered
One step improves the firm performance and used life of spanner, highly reliable.
It is pointed out that the tetragonal nut that rectangle sets of holes 3 and the size of handle 2 match as needed in the utility model
Size set.Exemplified by this sentences the special spanner of tetragonal nut used in Fa Na sections BT lengthening handle of a knifes, the length of left spanner 1
L1For 21mm, the left height H of spanner 11For 25mm, the length L of handle 22For 118mm, the height H of handle 22For 15mm, rectangle sets of holes
3 width W3For 13mm, the height H of rectangle sets of holes 33For 15mm.
As second of preferred embodiment of the present utility model, as shown in figure 3, the area with the first preferred embodiment
It is not that the right-hand member of handle 2 is provided with right spanner 5, the thickness of right spanner 5 is more than the thickness of handle 2, and left spanner 1 is pulled for circular
Head, right spanner 5 are the open type spanner of opening to the right.The diameter R of circular spanner is 12.5mm, the A/F W of right spanner 56
For 15mm.When running into the not high tetragonal nut or hex nut of torque requirement, it is adjusted using right spanner 5, when running into power
When square requires higher nut, such as the tetragonal nut on handle of a knife, it is adjusted using left spanner 1, it is new improves this practicality
The scope of application of type, it is practical.When nut position relatively narrower, the circular spanner of same size rotates than rectangle spanner
Angle it is bigger, fastened by screw and dismounting operating efficiency it is higher and easy to operate, it is simple and practical.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that,
