Abstract

The utility model relates to a novel screwdriver with a sharp edge. The novel screwdriver with the sharp edge comprises a cross screwdriver head and a cylindrical screwdriver handle, wherein each edge of the ends of the cross screwdriver is blade edge shaped; the screwdriver head is detachable from the screwdriver handle; one end of the screwdriver head is provided with an external spline to form a spline end; one end of the screwdriver handle is connected with a connecting shaft provided with an internal spline; the external spline of the spline end is matched with the internal spline of the connecting shaft. According to the novel screwdriver with the sharp edge, a bolt with a rusted or damaged surface can be loosened and tightened easily by the screwdriver with the blade edges, and moreover, the rusted bolt can be knocked by a square hammer connected to the rear end of the screwdriver handle so that the bolt can be screwed down conveniently by loosening the bolt; in addition, the square hammer is embedded with a magnet structure, so that the bolt can be attracted by the magnet when a hand cannot reach the bolt; the torque is increased by a gripping handle arranged on the screwdriver handle, so that the labor is saved.

Description

Novel sharp sword screwdriver
Technical field
The utility model relates to a kind of five metals apparatus, particularly relates to a kind of novel sharp sword screwdriver.
Background technology
In daily life, the usage frequency of screwdriver is very high.At present, traditional screwdriver, its structure generally includes: handle of a knife and its one end are arranged on the knife bar in handle of a knife, and the other end of knife bar is provided with cutter head.During use, this screwdriver can only slack adjuster, and function ratio is more single; And screwdriver often just can not be brought into play its effect after cutter head damage or screw get rusty.
Chinese invention patent CN 102653086 A patents are announced a kind of screwdriver, and it is comprised of the light-emitting device of cutter head 1, handle of a knife 2, handle of a knife front end and the magnet 4 of handle of a knife rear end as shown in Figure 1, and its light-emitting device is comprised of light emitting diode 3 and switch 5; In handle of a knife 2, being provided with built-in power is connected with light-emitting device.The screwdriver of this structure has the ability of working in the dark, and when hand reaches screw, can adsorb screw with magnet.But after screw surface abrasion or upper rust, this screwdriver just no longer can play the ability of rotary screw.
Summary of the invention
The technical problems to be solved in the utility model is: once overcome in prior art, driver bit is injured does not just have the ability of unscrewing screw, and a kind of novel sharp sword screwdriver is provided.
For solving the problems of the technologies described above, structure of the present utility model comprises that cross plays cutter head, cylindrical knife shank, cross plays the blade-like that is shaped as between each rib of cutter head end, cutter head and handle of a knife are dismountable, one end of cutter head is provided with external splines and has formed splined end, one end of handle of a knife connects the spindle with internal spline, and the external splines of splined end and the internal spline of spindle match.
Further: the end of thread that the other end of described handle of a knife is provided with screw thread formation is connected with the square hammer that is threaded hole.
Further again: in described square hammer, to be inlaid with magnet.
Further again: the middle part of described handle of a knife is equipped with manhole, and in manhole, insert cylindrical lever.
Further again: ball-type termination is equipped with at the two ends of described cylindrical lever, and the diameter of this ball-type termination is greater than the diameter of through hole.
Adopt after said structure, the utility model can not only get rusty by the driver bit effects on surface with blade or have the screw of damage to carry out degree of tightness operation, and can knock the screw that screw thread gets rusty with the square hammer that handle of a knife rear end connects, its generation is become flexible conveniently it is screwed down; Owing to inlaying this structure of magnet on square hammer, be for adsorb screw with magnet when hand reaches screw again, the cylindrical lever of installing on handle of a knife is in order to increase moment of torsion, saves strength.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure: 1 is cutter head, 2 is handle of a knife, and 3 is light emitting diode, and 4 is magnet, and 5 is switch, and 6 is spindle, and 7 is splined end, and 8 is square hammer, and 9 is manhole, and 10 is lever, and 11 is ball-type termination, and 12 is the end of thread
The specific embodiment
The utility model relates to a kind of novel sharp sword screwdriver, its structure comprises that cross plays cutter head 1, cylindrical knife shank 2 as shown in Figure 2, cross plays the blade-like that is shaped as between each rib of cutter head end, and the screw that can effects on surface has has worn and torn or got rusty with the cutter head 1 of blade carries out degree of tightness operation; Cutter head 1 is dismountable with handle of a knife 2, in one end of cutter head 1, be provided with external splines and formed splined end 7, one end of handle of a knife 2 is connecting the spindle 6 with internal spline, the internal spline of the external splines of splined end 7 and spindle 6 matches, in use splined end 7 is connected with spindle 6, during rotation, by spline joint, they is not relatively rotated.
The other end of handle of a knife 2 is provided with screw thread and has formed the end of thread 12, and the end of thread 12 is connected with the square hammer 8 that is threaded hole.This structure is the screw in order to answer double thread to get rusty, and by knocking screw, makes it become flexible and by rotation, screw be taken out with corresponding screwed hole generation.
In described square hammer 8, be inlaid with magnet 4, this structure is in order to tackle when hand reaches screw, can directly use with one end of magnet and remove to adsorb screw, has facilitated operation.
The middle part of described handle of a knife 2 is equipped with manhole 9, and has inserted columniform lever 10 manhole 9 is interior, and this structure is in order to increase moment of torsion, to save strength; Ball-type termination 11 is equipped with at the two ends of cylindrical lever 10, and the diameter of this ball-type termination 11 is greater than the diameter of manhole 9, and this structure is in order to make cylindrical lever 10 not drop out from the manhole 9 of handle of a knife 2 when carrying.
Certainly, the splined end 7 of this handle of a knife 2 also can be installed a word and be played cutter head, outer-hexagonal cutter head, interior hexagonal cutter head etc.Within such conversion all drops on protection domain of the present utility model.
