ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a Mohs tapered handle remover, and more particularly, to a handle remover that allows easy removal of a knife tool with time and effort saving and safe operation.
2. Description of the Prior Art
Whereas, in the prior art as shown in
FIGS. 1 and 2
, a Mohs tapered handle
1
is mainly for mounting a knife tool
2
(such as a bit, taper bit, formed tool, etc. where a bit is taken as an example in the following demonstration). If it is desired to remove the tool
2
, a triangular iron
21
is extended into the long slot
11
of the tapered handle bottom, then struck with a hammer to remove the bit
2
. This method is not only time and effort wasting, but also can be dangerous.
The main goal of this invention is to provide a Mohs tapered handle remover which can easily remove a knife tool and ensure time saving, effort saving and safe operation, to fully eliminate the defects of the prior art.
SUMMARY OF THE INVENTION
In brief, the present invention enables a user to remove a bit from a MOHS tapered handle by rotating a knob on a first end of the device to actuate the device. The knob, through a threaded interface, drives a slide rod outward. The slide rod causes a raising block to separate from a slide seat, thereby driving the bit out of the handle. The device enables the user to use rotational force instead of a direct force to remove the bit.
