Abstract

The utility model provides a kind of allen wrench, including hex screwdriver bit, handle and extension bar, and hex screwdriver bit includes the hexagonal prisms termination being on same axis and cylindrical base, hex screwdriver bit are removably attached to the front end of handle by the cylindrical base;The cavity of one end open is equipped with handle, extension bar is packaged in the cavity by the lid end in handle end;The through hole that handle is coincide and extended vertically through with the shape of the cross section of extension bar and size is additionally provided with the side of handle.Using the technical solution of the utility model, the mutual conversion of diversified forms spanner can be not only realized, and the screw that can be directed to different size replaces corresponding hex screwdriver bit, it is easy to use;Extension bar can also be loaded in handle when not in use at the same time, be convenient for carrying and not easy to lose, realized the effect of multi-purpose content.

Description

A kind of allen wrench
Technical field
It the utility model is related to Wrench field, and in particular to a kind of allen wrench.
Background technology
Allen wrench is a set of common hardware tool, common to have yi word pattern, L-type and T font allen wrenches, can To be respectively suitable for different occasions.For example, when being that soket head cap screw and rotation angle are less than 60 ° by fastener, tradition L types allen wrench can not just fasten this soket head cap screw, it is necessary to use T font allen wrenches;And hexagonal in L-type Spanner when in use, then can be tightened more easily or removable screw by the effect of moment of torsion, make up hexagonal in yi word pattern The deficiency of spanner.
However, above-mentioned different classes of allen wrench is each independent at present, must correspond in varied situations select or Carry, this will cause user to need to buy all kinds of allen wrenches respectively, bring the inconvenience used.
Utility model content
The purpose of the utility model is to overcome shortcoming existing in the prior art, there is provided hexagonal is pulled in one kind collection yi word pattern Hand, L-type allen wrench and T fonts allen wrench can be carried with, strong applicability in the allen wrench of one.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of allen wrench, including hex screwdriver bit, handle and extension bar;Wherein, hex screwdriver bit is included in same Hexagonal prisms termination and cylindrical base on axis, before hex screwdriver bit is removably attached to handle by the cylindrical base End;The cavity of one end open is equipped with handle, extension bar is packaged in the cavity by the lid end in handle end;Handle Side on be additionally provided with the through hole that handle is coincide and extended vertically through with the shape of the cross section of extension bar and size.
Further, hex screwdriver bit is removably inserted in the mounting hole of handle front end by cylindrical base, mounting hole It is coaxially disposed with handle;Handle front end also evenly distributedly offers some grooves, the opening direction of groove in the axial direction Handle front end.
Further, the front end of handle is cased with stiffnut.
Further, the bottom of mounting hole is further fixed on magnet.
Further, the position of cylindrical base side bottom is equipped with a pair of plane being centrosymmetric.
Further, the front end termination of handle is equipped with chamfering.
The utility model has the advantage that:
(1)Pass through the cooperation of through hole and extension bar on handle, it is possible to achieve yi word pattern, L-type and T font allen wrenches Between conversion, facilitate user and handle the situation of different occasions, and saved financial cost;
(2)During without using extension bar, extension bar can be hidden in handle, and not only compact is convenient for carrying and the side of taking Just, while the integrated setting of extension bar and handle is simple in structure, also so that extension bar is not easy to lose;
(3)Due to the cylindrical base using unified specification, even the hex screwdriver bit of different size can also substitute Using so as to being widely used in the installation of various sizes of screw and dismounting, strong applicability.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the installation diagram of the utility model.
Fig. 3 is the sectional view of the utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
Referring to the drawings.The utility model includes hex screwdriver bit 1, handle 2 and extension bar 3;Wherein, hex screwdriver bit 1 includes Hexagonal prisms termination 10 and cylindrical base 11 on same axis, specifically, cylindrical base 11 is cylinder and cross section Area is more than the cross-sectional area of hexagonal prisms termination 10, to strengthen moment of torsion.Hex screwdriver bit 1 by the cylindrical base 11 removably It is fixed in the mounting hole of 2 front end of handle, particularly, the position of close bottom is in center equipped with a pair on 11 side of cylindrical base Symmetrical cutting plane 12, can prevent the relative rotation between hex screwdriver bit 1 and handle 2, improve the transmission efficiency of moment of torsion.
2 front end of handle also evenly distributedly offers four grooves 8 in the axial direction, the opening of its further groove 8 is towards hand The front end of handle 2.Only need to change the hex screwdriver bit 1 with correspondingly-sized specification when therefore, for the screw of different size, Its installation is quick and convenient.
2 mounting hole bottom of handle is additionally provided with magnet 7, can strengthen consolidating to hex screwdriver bit 1 by the suction-operated of magnet 7 It is set for using, so that the transmission of auxiliary torque.The front end of handle 2 is also cased with stiffnut 6, can effectively protect hex screwdriver bit 1 to exist Deformed upon during force, extend the service life of hex screwdriver bit 1.
The cavity 9 of one end open is equipped with handle 2, extension bar 3 in the lid end 4 of 2 end of handle by being packaged in In the cavity 9.It is additionally provided with the side of handle 2 and matches and vertical with handle 2 pass through with the shape of the cross section of extension bar 3 and size The through hole 5 worn.When running into the situation for needing increase force, extension bar 3 half is inserted in through hole 5 hexagonal in i.e. achievable L-type and is pulled The function of hand;If extension bar 3 is further passed through into through hole 5, you can L-type allen wrench is converted into T font allen wrenches Use, occasion is not had to reply, realizes the beneficial effect of multi-purpose content.
It should be pointed out that the embodiment of the utility model is described above.However, the technical staff of art technology should manage Solution, the present utility model is not limited to the above embodiments, the principle for simply illustrating the utility model described in above-described embodiment, The utility model also has a variety of changes and improvements on the premise of the scope of the utility model is not departed from, these changes and improvements are all Fall into claimed the scope of the utility model.
