Description

A kind of auxiliary rotary handle for screw-jack

Technical field

This utility model is related to a kind of rotary handle, particularly relates to for the auxiliary rotation handss in car screw-jack Handle.

Background technology

Screw-jack has extremely wide purposes as driver's tool.As screw-jack is by the rotation of screw thread pair The height that rises that transhipment is moved to change its top position, therefore the screw rod when jack in screw thread pair under the conditions of heavy duty or underloading exists Make the rotating speed for relatively rotating in nut, can increasingly obtain the great attention of technical staff.Traditional screw-jack is in reality Using in, either whether jacking header pushes up heavy loading object, is all lentamente to turn very much on the premise of using same operation handle Dynamic external screw thread, this top for allowing for jack often will rotate screw rod by operator and be lot more time to top to weight to be lifted Initial position, then could formally jacking automobile or weight, so as operations such as emergency replacement automobile tires in make User operates very laborious and mood how anxious；Again：Some have the screw jack of tool kit in non-working condition When be to be affiliated to be positioned at jack this body side surface by the tyre wrench for having jack operation handle concurrently, to make this positioning mode It is able to reliability to lock or unlock, then needs to tighten or unscrew the power screw thread pair of jack, but for fear of the tire with operation handle Spanner has been hung in the first face of jack body, therefore operator can only struggle with reverse outer the six of lifting screw with finger Angle, forms the tyre wrench and is contained on jack body after positioning as the moment of torsion of such turn screw thread pair is not big enough Twist not tight or fail to lay down, the reliability of practical operation is poor, also result in tyre wrench easily mutually de- in reality is jolted with car Fall to damaging or the undesirable conditions such as people are disturbed because loosening generation vibrating noise.

The content of the invention

So, in view of above-mentioned screw-jack and combinations thereof instrument is being occurred using in or under the state that is contained Deficiency, designer are the auxiliary rotary handle that the screw rod outer-hexagonal entity of screw-jack has dressed a working of plastics, for solving Certainly：Increase the power arm for reversing screw rod with the top of the jack that adapts to relaxedly and rapidly to rise under jack idle condition and work It is driving handle tyre wrench locked on jack body or is loosened.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions：A kind of auxiliary for screw-jack Rotary handle includes torsion handle body, interior hexagonal through hole, it is characterized in that：Energy and spiral shell are offered in the middle part of the entity of torsion handle body The outer-hexagonal entity of bar implements the interior hexagonal through hole that gap coordinates；The bottom of torsion handle body is provided with the flange I that shakes hands, torsion The upper end of handle body is provided with the flange II that shakes hands；The rear end face of torsion handle body is a smooth flat, and its front end face is a benchmark Plane；Be provided with eight strainer lugs being distributed on same circumference above inner hexagonal hole inner face, the first strainer with Second strainer is symmetrical；3rd strainer is symmetrical with the 4th strainer；5th strainer is symmetrical with the 6th strainer；7th is elastic Button is symmetrical with the 8th strainer；Each strainer is in the form of an " L ", and the upper surface of each strainer is respectively positioned on same datum plane.

Wherein, physically offer blind hole I positioned at the flange II that shakes hands, physically offer blind hole in the flange I that shakes hands II。

Wherein, be evenly equipped between the lug entity of each strainer the first U-type groove of pattern identical, the second U-type groove, the 3rd U-type groove, the 4th U-type groove, the 5th U-type groove, the 6th U-type groove, the 7th U-type groove, the 8th U-type groove.

Wherein, the material of the torsion handle body is ABS plastic.

The beneficial effects of the utility model are：One working of plastics has been dressed by the screw rod outer-hexagonal entity for screw-jack Auxiliary rotary handle, for increase reverse screw rod power arm and adapt to relaxedly and rapidly to rise under jack idle condition Or rapidly fall the top of jack and tyre wrench on jack body is locked or put by reinforcing ground turn screw rod Pine, meets the actual demand of user with fine design.
