Description

Dual-purpose screwdriver

Technical field

The utility model relates to dual-purpose screwdriver, belongs to the common tool field.

Background technology

Screwdriver generally only has a cutter head, and cross-shaped knife and a word cutter are the most common, but carries two screwdrivers simultaneously and taken again too much space, and simultaneously, the regular work high above the ground for the electrician, take equipment back and forth from kit bag very inconvenient.

In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.

Summary of the invention

The purpose of this utility model provides a kind of dual-purpose screwdriver, with solution, carries the problem that two screwdrivers took up room, changed the screwdriver inconvenience.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of dual-purpose screwdriver, it comprises handle of a knife, knife bar and movable cutter head, the two ends of described movable cutter head are respectively cross-shaped knife end and a word cutter end, described movable cutter head middle part is to the two side-prominent hinge bars that are provided with, described knife bar hinged end comprises the U-shaped knife rest that axially stretches out and arrange, on the two side of described U-shaped knife rest respectively corresponding described hinge bar be provided with the chute of closed at both ends, described hinge bar is hinged and be slidably connected in described chute, described knife bar hinged end is provided with an inner chamber that holds described movable cutter head, described inner chamber is the polygon inner chamber, described movable cutter head is the movable cutter head of polygon that corresponding described polygon inner chamber arranges.

Base the above, be provided with movable pin on described intracavity sidewall, described movable cutter head two ends corresponding described pin respectively are provided with pin-and-hole.

Base the above, described movable pin is arranged in described intracavity sidewall, described removable pin nails on and is provided with positive stop lug boss.

The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model synthesizes cross and straight screwdriver on a cutter head, by hinged relation, occasion rotation blade at needs, use applicable cutter head instead, the staff only need carry a cutter head, has saved space; Simultaneously, be provided with the inner chamber that holds cutter head on knife bar, inner chamber and cutter head all are set to polygon, make cutter head put into inner chamber, and in use, cutter head can not rotate, and impact is used; Pin is set, makes its structure more firm, it has advantages of design science, simple in structure, a cutter is dual-purpose, simple to operate.
