Description

A kind of box spanner molectron

Technical field

This utility model is related to hardware ＆ tools technical field, more specifically a kind of box spanner molectron.

Background technology

Sleeve, such as patent CN201120397750.9 are recorded, and including a cylinder, the big one end of the cylinder internal diameter is Inner hexagonal hole, the little one end of internal diameter are square opening, have a transition shoulder, wherein square between the square opening and inner hexagonal hole Hole is for connection to the force application means such as spanner, and what inner hexagonal hole was then used as acting body.

Bolt is that we are daily sees most bodies that are applied, and although the nut of bolt tail is mostly outer-hexagonal, but It is square hole that also some is end face indent.Wherein, the former uses general sleeve, but the latter then needs to select general The variant tool of sleeve, box spanner side's tenon drive link as disclosed in patent CN201520753938.0, one end is collet head, separately One end is square tenon, is connected with a connecting rod between collet head and square tenon.

However, during our routine uses, not only the nut size of bolt tail is different, and sometimes spanner Ratchet area of bed is also different, so the hardware ＆ tools of single specification can not meet wide variety of demand.

Utility model content

The purpose of this utility model is to overcome the hardware ＆ tools of the single specification of prior art meet wide variety of The defect of demand, there is provided a kind of specification is more, install simple and quick flexible, the reliable box spanner molectron of stable connection.

In order to reach object above, this utility model is achieved through the following technical solutions：A kind of box spanner combination Part, it is characterised in that including two relatively independent drive links and driving head, the two ends of the drive link are respectively arranged with first Square tenon and the first collet head, the endoporus of first collet head is the first square opening, the driving head by second party tenon and The first body of second sleeve is connected and composed, and the endoporus of the second sleeve head is the second square opening, wherein the second party tenon with First square opening is adapted on specification, and the specification of second square opening is less than the rule of first square opening Lattice size, the specification of also described first party tenon are less than the specification of the second party tenon；The driving head exists Laterally running through perpendicular to its axle center on the region that second sleeve head is located has the groove for allowing the drive link to pass through.

This utility model has various different specification size side's tenons and collet head, can meet wide variety of demand, And the square tenon of these different specification sizes and collet head are located on two relatively independent drive links and driving head, and they are Can be combined use, can disperse again to use so that install simple and quick flexible.Additionally, the groove and energy on driving head It is enough which is connected in series with drive link, it is easy to carry, force application rod can be played a part of again, it is big using lever principle torsion.

Preferably, the wherein one side and groove of the wherein one side of the first party tenon, second party tenon A post holes inwardly dug is respectively arranged with internal face, the exit of each post holes is closed up, in each described post holes A freely movable spin is put into, each spin is implanted with a compression spring between corresponding post holes bottom.

Compression spring is by the internal face of the end face or groove of spin ejection side tenon, but spin is by the closing in post holes exit Fettered, when square tenon is inserted in the square hole bolt of end face indent or drive link is penetrated in groove, spin is squeezed into post holes In, compression spring stores that power is counter pushes away spin, and spin props up the body of rod of square hole medial wall or drive link so that square tenon and square hole or biography The stable connection reliability of lever and driving head.

Preferably, a blind slot for caving inward is respectively arranged with four internal faces of the first square opening.

In order to coordinate the spacing stablizing effect of spin, blind slot is used for and spin is engaged.

Preferably, being respectively arranged with one along respective corner angle on respective four corner angle of the first square opening and the second square opening The groove of length direction arrangement, the cross section of every groove is in circular arc.

So that the instrument such as sleeve and spanner or be applied between thing combine it is more smooth flexibly, also ensure that endoporus corner angle Intensity.

Preferably, the respective exit of the first square opening and the second square opening is respectively disposed with bore from inside to outside gradually Become the big guiding conical surface.

The conical surface is oriented to as the term suggests being exactly to facilitate the instruments such as sleeve and spanner or be applied between thing to combine more smooth spirit It is living.

Beneficial effect：This utility model has various different specification size side's tenons and collet head, can meet extensive Various demands, and the square tenon and collet head of these different specification sizes is located at two relatively independent drive links and driving head On, they can combine use, can disperse again to use so that install it is simple and quick flexibly.Additionally, on driving head Which can be connected in series by groove again with drive link, easy to carry, can play a part of force application rod again, be turned round using lever principle Power is big.
