Description

A kind of combination wrench
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of combination wrench.
Background technology
Spanner is a kind of conventional installation and removal instrument, utilizes lever principle to twist bolt, screw, nut and other screw threads and tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is conventionally shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist bolt or nut and hold opening or the trepanning of bolt or nut.When use, apply external force along screw thread rotation direction at shank, just can twist bolt or nut.
As everyone knows, the arm of spanner is longer, and the moment that same function power can produce is just larger, but long portability, transportation and the collection that can affect spanner of the arm of spanner.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of combination wrench is provided, and technical problem to be solved in the utility model is that how to realize the length of spanner arm adjustable.
The purpose of this utility model can realize by following technical proposal: a kind of combination wrench, it is characterized in that, described spanner comprises arm one and arm two, described arm one is hollow tubular, described arm two can be plugged in described arm one, the outer wall of described arm two is provided with a container cavity, in described container cavity, be provided with a steel ball, between described steel ball and the bottom of container cavity, be provided with a back-moving spring under impaction state, described arm one is provided with some spacing holes, described steel ball can snap in described spacing hole, it is first that one end of described arm one has the spanner vertical with arm one, one end of described arm two has the driving end vertical with arm two two.
Operation principle of the present utility model is: for the arm that makes combination wrench can stretch, the mode that adopts arm one and arm two to combine, arm one is hollow tube, arm two is inserted in the cavity of arm one, arm two is provided with can compressed steel ball, sliding handle two can make steel ball snap in spacing hole, thereby make the arm of this combination wrench scalable, can be in use laborsaving, and this combination wrench is also convenient to collection and transportation, on arm one and arm two, be respectively equipped with the first and driving end two of spanner, can carry out dismounting to the nut of different size or type.
In above-mentioned a kind of combination wrench, the outer wall of described arm two is provided with some splines one, and the inwall of described arm two is provided with the spline two coordinating with described spline one.Spline one and spline two coordinate, and in the time moving arm one or arm two, can not be subjected to displacement between the two.
In above-mentioned a kind of combination wrench, the diameter of the opening part of described container cavity is less than the diameter of steel ball.The opening part of container cavity is being put into after steel ball and back-moving spring, adopts the mode of knocking that the diameter of opening is diminished, and steel ball can not drop out in container cavity, take arm one and arm two apart, both all can use separately, to avoid the restriction in space, and can not use this combination wrench.
In above-mentioned a kind of combination wrench, described spanner is first is outer-hexagonal.
In above-mentioned a kind of combination wrench, described driving end two is interior hexagonal.
Compared with prior art, the utlity model has following advantage:
1, for the arm that makes combination wrench can stretch, the mode that adopts arm one and arm two to combine, arm one is hollow tube, arm two is inserted in the cavity of arm one, arm two is provided with can compressed steel ball, sliding handle two can make steel ball snap in spacing hole, thereby make the arm of this combination wrench scalable, can be in use laborsaving, and this combination wrench is also convenient to collection and transportation, on arm one and arm two, be respectively equipped with the first and driving end two of spanner, can carry out dismounting to the nut of different size or type.
2, the opening part of container cavity is being put into after steel ball and back-moving spring, adopts the mode of knocking that the diameter of opening is diminished, and steel ball can not drop out in container cavity, take arm one and arm two apart, both all can use separately, to avoid the restriction in space, and can not use this combination wrench.
