The purpose of this utility model is achieved through the following technical solutions:
A kind of improvement structure of flexible spanner, comprise handle, be fixed on the lip of pulling of handle one end, also comprise and be fixed on the pullover of the handle other end, describedly be provided with regular polygon running-on in pullover, described handle comprises sleeve, set bolt and is positioned at the connecting rod of sleeve, on described sleeve, be provided with locating hole, on described connecting rod, be provided with at least 3 through holes that equidistantly distribute, described set bolt is connected in locating hole and one of them through hole, at described connecting rod outer surface, be provided with keyway, in sleeve interior surface, be provided with the raised line matching with keyway.The utility model changes the position of connecting rod in sleeve by adjusting the through hole being connected with set bolt, realize the flexible of handle, thereby change the length of handle, spanner one end is for pulling lip, the other end is conventional pullover of box spanner, applicable different types of bolt, screw, workpiece etc., easy to use, highly versatile; By being provided with keyway at connecting rod outer surface, in sleeve interior surface, be provided with the mode of the raised line matching with keyway, can increase the motion uniformity of connecting rod and sleeve, when the wall thickness of sleeve reaches certain thickness, also can adopt the structure of keyway and raised line location swap, in use, cooperation due to keyway and raised line, increase torsional moment, can play the effect of skidding of preventing, avoided relatively rotating between connecting rod and sleeve.
For making the pullover use of above-mentioned telescopic spanner more convenient, further, this telescopic spanner also comprises for connecting handle and pullover elbow.
Because present most of bolt and screw are hexagonal structure, be to coordinate with it better, as preferably, above-mentioned running-on be shaped as regular hexagon.
Further, the above-mentioned lip of pulling comprises staying and pulls lip, lives and to pull lip and to pull the turbine that lip is connected with living, above-mentioned stay to pull on lip be provided with non-return nail, non-return nail is positioned at turbine one side.This non-return nail can avoid turbine to pull lip and move to change and pull a mouthful yardstick adjusting again to rotate after pulling mouthful yardstick and drive to live.This non-return nail can also rotate staying to pull on lip.
For strengthening the intensity of this telescopic spanner, as preferably, above-mentioned handle, pull lip, pulloverly by chrome alum steel alloy or nickel-chrome alloy steel, make.
The utility model compared with prior art, has following advantage and beneficial effect:
The improvement structure of a kind of flexible spanner of 1 the utility model, by being provided with keyway at connecting rod outer surface, in sleeve interior surface, be provided with the mode of the raised line matching with keyway, can increase the motion uniformity of connecting rod and sleeve, when the wall thickness of sleeve reaches certain thickness, also can adopt the structure of keyway and raised line location swap, in use, the cooperation due to keyway and raised line, has increased torsional moment, can play the effect of skidding of preventing, avoid relatively rotating between connecting rod and sleeve;
The improvement structure of a kind of flexible spanner of 2 the utility model, carries with easy to use, and spanner one end is for pulling lip, and the other end is pullover, easy to use, the highly versatile that box spanner is conventional; Between pullover and handle, adopt elbow to be connected, use more laborsaving and convenient; Simple and compact for structure, cost is low easy for installation, economic and practical.
