Description
Technical field
The utility model belongs to hand-operated tools field, especially related with a kind of multifunctional combination wrench.
Background technology
Existing combination wrench can operate different model screw or screw rod, then also there are driving ends more
Complicated disadvantage is changed, and when driving end quantity is more, driving end is easy to be lost.Additionally, due to existing driving end volume compared with
Greatly, it is unfavorable for the place more narrow in space to be operated.
Utility model content
Place complicated, cannot be more narrow in space is replaced for driving end existing for existing combination wrench to be grasped
The problem of making, the utility model, which is intended to provide, a kind of to be replaced the place that convenient and driving end can be more narrow in space and is operated
Combination wrench.
For this purpose, the utility model uses following technical scheme：A kind of combination wrench, including handle, characterized in that further include
Four spanners, spanner are in pancake, and the both ends of spanner offer the driving end for switching bolt, nut, the hand
The both ends of handle are in pancake, the square through hole that the both ends of handle offer circular through hole and penetrated through with circular through hole；Four
Spanner reclines the top and bottom at the both ends for being installed on handle respectively, the spanner in same end by connecting pin connection,
The both ends of connecting pin are cylinder, and the middle part of connecting pin is in rectangular with the cooperation of the two side of the square through hole, in side
The connecting pin of shape part is provided with the through-hole with the connecting pin central axis, and the orifice diameter at the both ends of through-hole, which is less than, leads to
Roller is respectively set in the both ends of the diameter in hole, through-hole, is shored by spring between two rollers, the portion of roller is shored by spring
The aperture for exposing through-hole, the two side of the square through hole is divided to be equipped with the circular groove coordinated with roller, connecting pin passes through
The circular groove of the two side of roller and square through hole coordinates to connecting pin cross spacing.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The driving end is double offset ring spanner, and the diameter for pulling mouth of driving end differs.
The mouth of pulling of the driving end is equipped with multiple arc-shaped convex arranged along endoporus center of circle even circumferential, by this
The driving end for pulling mouth formation is adapted to the operation of standard bolt and non-standard bolt.
The aperture of the through-hole of the connecting pin is stamping by pier nose.
The tabletting that the both ends setting of the connecting pin and the outer end face of the spanner recline.
The utility model can reach following advantageous effect：The utility model passes through roller by connecting pin and square through hole
Against the positioning for realizing spanner, so as to realize the switching of spanner, when needing to switch the other end to the outside of spanner, push
The circular through hole direction movement penetrated through with square through hole is sold in connection, and roller compresses realization into the through-hole of connecting pin due to stress
The movement of connecting pin, connecting pin can switch very convenient spanner free switching orientation when being placed in round hole.This practicality is new
Type handle and handle are in pancake, so as to so that spanner stretches into more narrow space is operated.
