The survivor of a murder attempt pull in the industry, on the agricultural, all be indispensable a kind of instrument aspect the communications and transportation, family life, be used widely for many years.
At present, the widely used survivor of a murder attempt pulls by fixedly pulling three parts of body, Flexible spanner body, worm screw and forms, and the rotation that this survivor of a murder attempt pulls easily because of worm screw causes dislocation, thereby causes nut or bolt chamfered edge.In addition, this spanner control worm screw location is slower, inefficiency.Therefore, be badly in need of wanting a kind of efficient, fastening effective a kind of survivor of a murder attempt to pull in the productive life and substitute it.
Summary of the invention:
The purpose of the utility model is to provide a kind of efficient, fastening effective survivor of a murder attempt to pull.
The utility model comprises that the survivor of a murder attempt pulls body, handle and cooperation spanner.It is a kind of scroll chuck that the survivor of a murder attempt pulls body; Scroll chuck is made up of claw, bevel gear wheel, bevel pinion, chuck body; The screens of claw is two planes that are mutually 120 degree; Have gear teeth to cooperate with bevel gear wheel on the claw, the claw side has groove to cooperate with chuck body, and bevel pinion cooperates with bevel gear wheel; Patchhole is arranged on the bevel pinion; Cooperate the rotation of spanner through patchhole control bevel pinion, the rotation of bevel pinion can drive the rotation of bevel gear wheel, and then regulates claw, pulls open a mouthful size thereby realize regulating the survivor of a murder attempt.
As the further improvement of the utility model, the tooth of bevel gear wheel is in the bevel gear wheel disk, and bevel pinion cooperates with the big vertebra gear is vertical, and the patchhole opening is in the face of cylinder, chuck side.
As the further improvement of the utility model, the tooth of bevel gear wheel on the bevel gear wheel side face of cylinder, bevel pinion and the parallel cooperation of big vertebra gear, the patchhole opening is in the chuck body disk.
As the further improvement of the utility model, cooperating spanner is T font spanner.
As the further improvement of the utility model, cooperating spanner is L font spanner.
The beneficial effect of the utility model: the cooperation spanner of the utility model is through the rotation of patchhole control bevel pinion, and the rotation of bevel pinion can drive the rotation of bevel gear wheel, and then regulates claw, thereby the realization adjusting survivor of a murder attempt pulls open a mouthful size, regulates the efficient height; The screens of the claw of the utility model is two planes that are mutually 120 degree, makes spanner can reach extraordinary fastening effect.Patchhole on the bevel pinion of the utility model can be arranged in the face of cylinder, chuck side or in the chuck body disk, can select wherein a kind of according to the usage space situation of different use occasions.
Description of drawings:
Fig. 1 is that the utility model survivor of a murder attempt pulls front view.
Fig. 2 is that the utility model bevel pinion is pulled the body structure sketch map with the vertical survivor of a murder attempt who cooperates of bevel gear wheel.
Fig. 3 is that the utility model cooperates the spanner structure sketch map.
Fig. 4 is that the survivor of a murder attempt that the utility model bevel pinion cooperates with the bevel gear wheel level pulls the body structure sketch map.
Fig. 5 is that the utility model survivor of a murder attempt pulls back side partial view.
Among the figure: 1 handle, 2 survivors of a murder attempt pull body, 3 chuck bodies, 4 claws, 5 bevel gear wheels, 6 bevel pinions, 7 patchholes, 8 cooperate spanner, 9 gear teeth, 10 screens.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further to specify.
During use, scroll chuck is placed on bolt or the nut, regulates bevel pinion 6 through cooperating spanner 8; Drive bevel gear wheel 5 rotations, and then regulate claw 4, scroll chuck and bolt or nut are closely cooperated; Rotary handle 2 then, and realization unscrews screw or screws.After reaching requirement, regulate cooperation spanner 8 and unload lower ejector lever.
The cooperation spanner 8 of present embodiment is through the rotation of patchhole 7 control bevel pinions 6, and the rotation of bevel pinion 6 can drive the rotation of bevel gear wheel 5, and then regulates claw 4, thereby the realization adjusting survivor of a murder attempt pulls open a mouthful size, regulates the efficient height; The screens 10 of the claw 4 of present embodiment is two planes that are mutually 120 degree, makes spanner can reach extraordinary fastening effect.Patchhole on the bevel pinion of present embodiment is arranged in the face of cylinder, chuck side, is applicable to that to cooperate spanner 8 to regulate the space in the front not enough and the occasion of regulating the space arranged in the side.
