Abstract

The invention relates to a hand drill, which consists of a crank, a drill rod, a drill bit and a drill pipe, wherein the crank, the drill rod and the drill bit are connected into a whole, and the drill bit can be replaced; the drill pipe is provided with two thick ends and a thin middle part so as to facilitate the hand gripping, and two bearings are respectively embedded into the two thick ends, and tightly sleeve the drill rod. When the hand drill is used, a proper drill bit is selected and installed, and one hand grips the drill pipe, the other hand grips the crank to rock the drill rod, and then a hole can be drilled. The hand drill has the advantages that the structure is simple, the convenience is realized, the labor is saved, and the hand drill is a necessary drilling tool for family life.

Description

A kind of hand drill
Technical field
The present invention relates to boring bar tool field, relate in particular to a kind of hand drill.
Background technology
The clumsy effort of old-fashioned hand drill, although new-type electric drill is laborsaving, once power failure or just using without electric field conjunction, affects work.The present invention is a kind of non-electric convenient and strength-saving hand drill instrument.
Summary of the invention
The present invention is made up of crank, drilling rod, drill bit, drilling pipe four part.Crank, drilling rod, drill bit are connected as a single entity, and drill bit is replaceable.Thin in the middle of drilling pipe two is thick, be convenient to hold, thick two respectively embeds a bearing.Two bearings are enclosed within drilling rod tightly.During use, select suitable drill bit good and sound, one holds drilling pipe, and another holds crank shake drilling rod, can hole.
Advantage of the present invention is that structure is simple, convenient and strength-saving, is the boring bar tool of family life indispensability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 crank in figure, 2 bearings, 3 drilling rods, 4 drill bits, 5 drilling pipes.
