ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a pounding tool, and more particularly to a hammer.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art hammer
5
comprises a main body
60
and a protective jacket
70
.
The main body
60
has a head
61
and a handle
62
which is provided with a top side
621
and a bottom side
622
. The direction extending from the top side
621
to the bottom side
622
is the same as the pounding direction of the head
61
.
The protective jacket
70
is made of a plastic material by injection molding and is fitted over the handle
62
to facilitate the gripping of the handle
62
.
Such a prior art hammer
5
as described above is defective in design in that the reaction force, which is brought to pass by the pounding action of the head
61
, is transmitted via the handle
62
and the protective jacket
70
to the hand holding the hammer
5
, thereby resulting in the numbness of the hand.
With a view to overcoming the drawback of the prior art hammer
5
, another prior art hammer
6
is provided on the protective jacket
80
thereof with two straight troughs
81
extending along the direction of the longitudinal axis of the protective jacket
80
such that the two troughs
81
are corresponding in location to the top side
91
and the bottom side
92
of the handle
90
for absorbing the shock wave. The protective jacket
80
is effective in mitigating the reaction force that is brought about by the pounding action of the hammer
6
; nevertheless the protective jacket
80
is not cost-effective. The troughs
81
of the protective jacket
80
are formed by drilling or injection molding. The drilling method is technically difficult and time-consuming, whereas the method of injection molding is technically infeasible because of the design problem of the molding tool and the problem of releasing the protective jacket from the molding tool in which the protective jacket is formed. For example, the molding tool must be provided with two long molding columns for forming the troughs
81
. The molding columns are vulnerable to deformation or severance.
SUMMARY OF THE INVENTION
The primary objective of the present invention is therefore to provide a pounding tool which is free from the drawbacks of the prior art pounding tools described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a pounding tool with a protective jacket which is fitted over the handle of the pounding tool and is provided with a plurality of shock-absorbing holes which are arranged in two rows and are respectively located over the top side of the handle and under the bottom side of the handle.
