2. Description of the Related Art In a conventional conductive hand tool, there is a ratchet spanner in which the principle of a planetary gear device is applied to a rotating body to accelerate the rotation of an output shaft. (For example, the actual Kaihei 4-13
6665). When the rotation load during work is small,
There is a manual rotary tool that improves workability by connecting the bit directly. (See, for example, Kaikaihei 6-57558).

[0003]

In the conventional conductive hand tool, when the input shaft (handle) makes one 360 ° rotation, the rotation of the output shaft (rotating body) is limited to four times as fast. Met. Further, if the range of reciprocal movement of the input handle (arm) in a narrow place is limited, there is a problem that the rotation itself of the output shaft (rotating body) is limited.

In the conductive hand tool of the present invention, an input gear portion which is a combination of an input handle (6) and an input gear (2),
It is a means for further increasing the rotation speed by combining the transmission gear part of the combination of the transmission gear and the chain gear, the output gear part (16) and the output gear part of the planetary gear device (17) and rotating them in conjunction. .

The means for accelerating the rotation of the above-mentioned device transmits the energy of the reciprocating motion that causes the input handle (arm) to vibrate vertically to the input gear (2) and the input chain gear (4),
The speed of rotation of the output gear (16) is increased.

The rotation speed is increased by halving the number of teeth of the transmission gear with respect to the number of teeth of the input gear (2), and the small chain gear is compared with the number of teeth of the input chain gear (4). The rotation speed is increased by halving the number of teeth of.

If the ratio of the output gear (16) to the number of teeth of the large transmission gear (12) is reduced, the speed is further increased.

When the number of teeth of the guide gear (24) bonded and fixed to the output gear (16) is allowed to rotate and rotate coaxially, the number of teeth of the output gear (16) is made to be several times larger than that of the guide gear. The rotation of (24) can be accelerated.

The guide gear (24) is replaced with the planetary gear unit (17).
If the gear teeth are interlocked with the outer teeth (23), the elements of the planetary gear unit (17) work and the rotation ratio is increased, and a large increase in rotation ratio is expected as a whole.

By fixing the shaft portion of the guide gear (24), the shaft portion of the output gear (16) and the shaft portion of the planetary gear unit (17) to the same mold, it is possible to cope with the diversification of the angle of the output position. .
