Abstract

The utility model discloses a hand-cranking traction device. The hand-cranking traction device comprises a frame and a traction wheel, wherein the traction wheel comprises a traction disk and a fixed disk; a driving disk is connected with the frame in a rotating manner through a cross bar; and the driving disk is fitted to the traction disk and is provided with a rotatable handle part. According to the hand-cranking traction device, a user can easily drive the traction disk by means of the gear fit between the driving disk and the traction disk and by means of the rotatable handle part, so that the physical strength of the user is greatly saved.

Description

A kind of shaking draw gear

Technical field

The utility model relates to a kind of tractor equipment, or rather, is a kind of shaking draw gear.

Background technology

In engineering construction or mining industry construction operation, need use tractor equipment, particularly during operation in the open air, in the absence of electric power supply, it is very important that manpower traction's draw gear seems.The drawbar efficiency of existing manpower traction's equipment is not high enough, and it is also convenient inadequately to use.

Summary of the invention

The utility model mainly is to solve the existing in prior technology technical matters, thereby a kind of shaking draw gear is provided.

The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:

A kind of shaking draw gear; Comprise framework and traction wheel; Described traction wheel comprises a sheave and a reaction plate; One driving disk is connected with described framework through a cross bar rotationally, and described driving disk matches with described sheave, and described driving disk is provided with a twist grip portion.

As the preferred embodiment of the utility model, described handle portion comprises a pipe link and a dwang.

As the preferred embodiment of the utility model, the outer circle wall of described driving disk is provided with driving gear, and the outer circle wall of described sheave is provided with traction teeth, described driving gear and traction teeth engagement fit.

The shaking draw gear of the utility model utilizes the gear matched of driving disk and sheave, and utilizes twist grip portion, and the user can drive sheave like a cork, has saved user's muscle power greatly.
