In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an instrument for twist nut soon fast, includes the headstock, one side of headstock is equipped with the grab handle, install first transmission shaft in the headstock, the fixed action wheel that is equipped with in the first transmission shaft, still be equipped with power device in the first transmission shaft, the action wheel is connected with from the driving wheel, install on the secondary drive axle from the driving wheel, the secondary drive axle sets up on the headstock, still the fixed belt pulley that is equipped with on the secondary drive axle, the belt is equipped with on the belt pulley, the belt passes and winds on the nut behind the opening that sets up in headstock tip both sides.

Furthermore, both ends of the first transmission shaft can be provided with a crank after penetrating through the power box, and the power device is a crank.

Further, the transmission ratio of the driving wheel to the driven wheel is 1: 10.

Further, both sides of the pulley are provided with rims for preventing the belt from falling off.

Furthermore, the driving wheel and the driven wheel are chain wheels or toothed belt wheels, and the driving wheel and the driven wheel are driven by chains or toothed belts.

Furthermore, a concave surface is arranged on one end face of the power box with the opening.

Compared with the prior art, the utility model, following beneficial effect has:

the utility model discloses an instrument for revolving fast soon nut uses, overlaps the belt on the nut, through the drive action wheel to transmit power for the belt pulley through following the driving wheel variable speed after, the belt pulley drives the belt and rotates, and the belt drives the nut and rotates. The utility model discloses can realize the quick precession or the back-out of nut. The utility model discloses simple structure can improve the efficiency of screw precession or screw-out among the mechanical equipment.

This section distance before the screw in screw rod reachs the screw rod bottom, nut rotating resistance is very little, need not to use the rotatory nut of spanner, and bare-handed can rotatory nut, no matter be with the rotatory nut of spanner or the rotatory nut of bare-handed, efficiency all is very low, and it is less that the moment of torsion is just when using this instrument work, but the rate of rotation is higher. Saves trouble and labor compared with manual screwing.

If the nut to be screwed in is located at the corner of the workpiece at an angle of 90 °, for example, the nut is screwed to the bottom of the screw by a wrench, the angle of rotation of the wrench per time is less than or equal to 90 ° so that the nut rotates no more than 1/4 cycles per time. The nut needs to be screwed to the bottom of the screw for a longer time. The belt of the tool can be easily sleeved on the nut, and the tool can be screwed in or out quickly.

In some limited places, when the nut cannot be screwed by a wrench, the tool is used, and only the belt is sleeved on the nut to finish quick screwing-in or screwing-out.

The tool is connected with chain wheels with different diameters through a chain (or a toothed belt) to transmit and improve the rotating speed of the driving wheel, and the driving wheel drives the belt to rotate at a high speed, so that the nut is driven to rotate quickly. The utility model discloses a can design into big, medium and small different specifications according to the equipment of work, the nut size that will rotate. The utility model discloses can design into like the handheld portable instrument of electric hand drill size, it is all more convenient to carry the operation.

The utility model discloses simple structure, it is portable. The nut rotating efficiency of the mechanical equipment can be greatly improved. Is suitable for the field operation, and places with limited electric tool use or wrench use.

The utility model discloses all install the crank at the both ends of first transmission shaft, can adapt to the demand of the worker of hand custom for different advantages.
