Abstract
The utility model relates to a safety hand-cranking bar for a motor vehicle and belongs to the tool for starting, comprising a control part, a driving part and a combination part. When the vehicle is started, a control wrench and a handle are grasped; a positioning shaft is combined with a combined shaft through the functions of a conical shaft and an oblique iron; the combined shaft is combined with the starting shaft of a motor vehicle; the handle is rotated for starting the motor vehicle; when the starting is finished, the conical shaft and the positioning shaft can return the original position under the function of the spring; the positioning shaft is disengaged form the combined shaft; even if the starting shaft of the motor vehicle reverses, and simultaneously, the combined shaft rotates; the whole cranking bar can not rotate; the injury of people caused by the reverse rotation can be avoided; the utility model is an ideal tool for starting the motor vehicle.
Description
The utility model belongs to the Motor Vehicle larry and starts instrument.
When having motor vehicle starting now, usually being situated between, it is a kind of simple to help
Type larry instrument still, because it does not adorn system safely, often because of the excessive or anti-electrical phenomena of gas tank pressure makes the crank counter-rotating, causes human casualty accident.
In order to address this problem, existing
The type crank can not solve reversal phenomenon, and causes the face phenomenon of hurting sb.'s feelings to take place again and again.
The purpose of this utility model is that a kind of Motor Vehicle safety handle that improved will be provided, and it can prevent and control the crank counter-rotating Motor Vehicle safety handle device that phenomenon takes place of hurting sb.'s feelings effectively:
The purpose of this utility model is to realize like this.
It forms control section, drive part by three parts, bound fraction is equipped with corresponding parts flexibly, when needs start in each part, hold with a firm grip and control wrench and hand tenon, make the diminished shaft reach, the compressing wedge bottom,, wedge is oppressed positioning shaft again, makes in its positioning hole that stretches into the combination axle, be connected as a single entity, combine with the starting shaft of locomotive again, shake handle in conjunction with axle, can open car, handgrip unclamps after opening car, diminished shaft, and positioning shaft is return the original place under the effect of pressure spring, positioning shaft is thrown off with the hole that combines axle, even if this moment, the train starting axle reversed, just the crank body does not change in conjunction with axle and then reverses, thereby has avoided counter-rotating to hurt sb.'s feelings, this Motor Vehicle safety handle is reasonable in design, make simply, cost is low, and is easy to use flexible, definitely avoiding counter-rotating to hurt sb.'s feelings, is the comparatively desirable turner tool that opens.
