ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The invention relates to a polygonal ratchet wrench with an illuminating device, and more particularly to a polygonal ratchet, which is capable of illuminating, bi-directional application and labor-saving.
(2) Description of the Prior Art
Please refer to
FIG. 1
for an exploded perspective view of a conventional ratchet wrench
1
. The conventional ratchet wrench
1
usually uses a socket
2
to fasten a screw or a nut upon a respective mechanical part. However, the duty of the conventional ratchet wrench
1
is only limited to perform fastening and loosening. In the case that a need exists to fix a machine in an obscure surrounding, an additional lamp or hand torch is required to illuminate the working area so that the conventional ratchet wrench
1
can work properly. Nevertheless, it is usual that the additional illuminating apparatus can not direct to the working position of the wrench
1
, so the operation of the wrench
1
is still difficult in such an obscure surrounding. Further, because a hand is occupied by the lamp or hand torch, the application of the wrench
1
and the handling of the screws and nuts can only be done by a single hand, from which the work can be substantially affected.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide a polygonal ratchet wrench with an illuminating device, in which the wrench provides a micro switch located at a lower rim thereof for controlling a lamp built at a matching body of the wrench. The lamp is used to illuminate the working position of the wrench for facilitating the wrenching operation.
It is another object of the present invention to provide a polygonal ratchet wrench with an illuminating device, in which a receiving hole on the matching body is provided at the opposing side to the lamp. By providing the receiving hole, an extension bar can be applied to operate the wrench of the present invention for labor saving.
It is a further object of the present invention to provide a polygonal ratchet wrench with an illuminating device, in which an action portion is included to control engagement of a control plate and a ratchet for determining the operation direction of the wrench.
All these objects are achieved by the paper-loading mechanism for a document duplicating machine described below.
