Description

FIELD OF THE INVENTION

The present invention relates generally to a hand tool, and more particularly to a mason's hand tool.

BACKGROUND OF THE INVENTION

As shown in FIGS. 1 and 2, a mason's hand tool of the prior art comprises a blade 105

DETAILED DESCRIPTION OF THE EMBODIMENT

As shown in FIG. 3, a hand tool embodied in the present invention is composed of a blade 10, a handle 20, and a head cap 30.

The handle 20 is fastened at one end thereof with the blade 10 which is used in spreading cement mortar or things of that nature. The cap 30 is fastened with the head end of the handle 20. In the preferred embodiment of the present invention, the handle 20 and the head cap 30 are made integrally of a rigid plastic material by injection molding. The handle 20 is provided on the outer surface of the one end thereof with a skidproof area 12 providing friction to enable the thumb and the index finger to hold the skidproof area 12 securely.

In order to enhance the fastening of the head cap 30 with the head end of the handle 20, the head cap 30 may be provided with a plurality of protrusions 31 each having a retaining head 32 which is greater in diameter than the protrusions 31, as shown in FIG. 5 and FIG. 7. The head cap 30 is thus securely attached to the handle 20, best shown in FIGS. 5 and 7. Now referring to FIG. 4, and FIG. 6, in another embodiment of the invention, the head cap 30 is provided with a plurality of threaded holes 35 and bolts 33 which are engaged with the threaded holes 35. Each bolt 33 has a head 34 which provides a similar function the retaining head 32 of FIG. 5. The head cap 30 is thus securely fastened with the handle 20, thanks to the protrusions 31 or the bolts 33 which are securely anchored in the head end of the handle 20. The head cap 30 of the present invention is not vulnerable to being separated from the head end of the handle 20 even if the head cap 30 is used to hit a nail or screw that is not completely fastened onto something.

The embodiment of the present invention described above is to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following appended claims.
