Description

Dual-purpose screwdriver

Technical Field

The utility model relates to a dual-purpose screwdriver.

Background

The screwdriver is one of the largest assembly tool of daily use, mainly there are word sword and cross sword, if be equipped with two screwdrivers simultaneously and can occupy more space, therefore, dual-purpose screwdriver appears at present, thereby reduce the quantity of screwdriver through switching the tool bit, but present dual-purpose screwdriver needs set up the cavity that is used for accomodating tool bit one of them one end in the handle of a knife, need extract the back with the tool bit is whole when the tool bit switches, insert in this cavity with the one end that will not use again, the tool bit switches inconveniently, reduce user of service's work efficiency, and the tool bit is taken out many times and is produced loosely, because the tool bit is linked together with the tool bit, can't satisfy the user demand of assembling not equidimension screw.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a dual-purpose screwdriver, this dual-purpose screwdriver can make things convenient for the tool bit to switch, improves user of service's work efficiency.

Solve above-mentioned technical problem, the utility model discloses the technical scheme who adopts as follows.

The utility model provides a dual-purpose screwdriver, includes the cutter arbor and has the tool bit of two knife tips, the one end of cutter arbor is connected with the handle of a knife, and the other end is connected with the knife rest, install in the knife rest the tool bit, its characterized in that, the knife rest is one end opening, the U-shaped frame that the other end is sealed, the blind end of knife rest with cutter arbor fixed connection, the both sides of knife rest are equipped with the trapezoidal spout that one end is narrow, the other end is wide, department is equipped with the bracing piece in the middle of the both sides of tool bit, the bracing piece has the little, the middle wide prism cross section in both ends, and bracing piece slidable mounting just slides along the length direction of spout in the spout, the wide mouth end of.

On the basis of the technical scheme, the utility model discloses can do following improvement:

the axial both ends of tool bit are a straight tool tip and a cross tool tip respectively.

The axial both ends of tool bit all are equipped with the magnetism cavity and cup joint the knife tip in the magnetism cavity.

Compared with the prior art, the utility model discloses the technique has following advantage:

(1) the dual-purpose screwdriver of the utility model has simple integral structure, and can facilitate the mutual switching between the straight screwdriver tip and the cross screwdriver tip, thereby improving the working efficiency of users;

(2) the utility model discloses an axial both ends of tool bit among the dual-purpose screwdriver all are equipped with the magnetism cavity and cup joint the interior knife tip of magnetism cavity to can satisfy different user demands.
