Abstract

PURPOSE: A device for converting the angle of rotary torque for a wrench is provided to improve working efficiency by enabling a worker to use the wrench even in a narrow space. CONSTITUTION: A device for converting the angle of rotary torque for a wrench is composed of a worm(1) formed at a driving shaft, a worm gear(2) formed at a driven gear, a wrench connection unit(3) extended from the driving shaft and connected to the wrench, a socket connection unit(4), a plurality of bearings(5) for supporting the driving shaft and the driven shaft, a handle coupling unit(8) connected to a handle, and a case(6) for fixing and enclosing the worm and the worm gear. The worm gear of the driven shaft is rotated by the rotation of the worm, and converts the rotary direction of the wrench and increases the rotary torque of the wrench.

Description

Rotary Torgue angled Converter

It is a device that converts the angle of rotation of the rotational force by 90 degrees so that you can easily tighten the bolt or screw in the space where the impact wrench or the screwdriver cannot be used. In addition, the auxiliary handle was detachably attached to the right angle screwdriver so that the screw could be tightened or loosened.

In general, bolts in narrow gaps in automobiles are not working with impact wrenches, but work with socket wrenches or spanners, but the reciprocating space of spanner handles is often insufficient, resulting in a loss of work efficiency.

Screw drivers are often used for relatively small and complex machines, and they have a lot of difficulty in loosening or tightening the tight gaps.

In order to solve the problems described above, the worm and the worm gear which can frequently tighten or loosen the bolts with a small force by increasing the torque when switching to the driven shaft instead of the bever gear which are frequently damaged by the gear and are difficult to manufacture small. It is an object of the present invention to convert a rotational angle of action to use an impact wrench even in a narrow gap, to use a screwdriver, to use a power tool, and to be able to tighten it manually with a small force. It is used and the auxiliary handle is detachable.

When described with reference to the accompanying drawings as follows. Figure 1 shows the impact direction and angle of operation while turning the worm gear (②) of the driven shaft while the worm (①) of the drive shaft rotates when the impact wrench is connected to the connecting portion (③) of the drive shaft for an impact wrench or socket wrench using a socket. , Torque increases as the torque decreases, so that the impact wrench and the large driver can be used as long as the torque angle converter can be inserted, thereby increasing the productivity (see FIG. 1).

In particular, worms and worm gears have a limitation in making the berber gears easy to move when the heavy load is applied, causing frequent breakdowns and very small, while worms (①) and worm gears (②) are easily pulled together by the force of the gears. It is not damaged and can be used by cutting the worm (①) and worm gear (②) directly on the shaft of the small driver, so there is little difference in size compared to the existing driver or socket wrench. Case (⑥) is a thin, slightly wide box, cylindrical, and can be used in a very narrow space. In addition, there is a handle fastener (⑧) made of a screw groove that can be connected to the handle, so when the general bolt is inserted, it becomes the base of the lever.

Especially in the case of a screw driver, the screw can be tightened by rotating the handle in a bent with a letter A. When the torque is transmitted to the driven shaft made of worm gear (②), the torque is reduced and transmitted. And by using the handle (⑦), there is an advantage that you can tighten or loosen the screw strongly, and the angle converter for impact wrench can be attached to the handle fastener (⑧).

In addition, it is possible to connect several angle converters so that various angle conversions are possible, so it is easy to fasten bolts where there is no reciprocating space of manual socket wrench.

As such, the present invention uses the present invention when tightening a bolt in a narrow gap where an impact wrench does not enter, so that an impact wrench can be used to increase productivity, and there is an obstacle on the top of the screw, and thus a screw that is forced to use a very short screwdriver is also used. With the present invention, a large driver can be used as a drive shaft, and torque can be increased easily and firmly by increasing torque.
