The front end face of the connector, which is recessed inwardly, sets the screens slot of a regular hexagon, and the screwdriver handle is internally provided with hollow tube
Road, one end of the hollow pipeline are connected to the rear end of the screens slot, and the open rearward end of the screens slot is more than the screens
The front opening of slot, a filler is opened up on the side wall of the screwdriver handle, and the filler lower end connects with the hollow pipeline
It connects, the rear end of the hollow pipeline connects one block of circular rare earth neodymium magnet steel, and the upper surface of the rare earth neodymium magnet steel is the poles N or S
The side of pole, the rare earth neodymium magnet steel connects a torsion shaft, and described reversing shaft one end exports the screwdriver handle side wall, described
The rear end both sides of screwdriver handle set accumulator tank, and the replacement cutter head of several species is set inside the accumulator tank, the replacement cutter head
Bottom end connects permanent magnet.
In a preferred embodiment of the present invention, the bottom face of the permanent magnet is the poles N or the poles S.
In a preferred embodiment of the present invention, one end of the torsion shaft connects sliding piece.
In a preferred embodiment of the present invention, the point diameter for replacing cutter head is more than the opening mouth of the screens slot
Diameter.
The beneficial effects of the invention are as follows：The present invention devise it is a can side carry out driver bit replacement function spiral shell
Silk knife, the replacement process of driver bit just seem for as single on pistol, driver bit enters internal pipeline from side, by
The repulsion generated to the magnet steel of Internal back end arrives front end bayonet to preposition, and reverse operating is to suck back driver bit, it is only necessary to be changed
The magnetic pole of one lower magnetic steel, it is very convenient.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment

Attached drawing, wherein：
Fig. 1 is that the structural schematic diagram of one preferred embodiment of cutter head type screwdriver is replaced in the side filling of built-in permanent magnet of the present invention；
The label of each component is as follows in attached drawing：1, screwdriver handle；2, connector；3, screens slot；4, hollow pipeline；5, filler；
6, rare earth neodymium magnet steel；7, reversing shaft；8, accumulator tank；9, cutter head is replaced；10, permanent magnet.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of side filling replacement cutter head type screwdriver of built-in permanent magnet, including screwdriver handle 1 and connector 2, the screw
The front end of handle of a knife 1 connects the connector 2, and the front end face of the connector 2, which is recessed inwardly, sets the screens slot of a regular hexagon
3, the screwdriver handle 1 is internally provided with hollow pipeline 4, after one end of the hollow pipeline 4 is connected to the screens slot 3
End, the open rearward end of the screens slot 3 are more than the front opening of the screens slot 3, one are opened up on the side wall of the screwdriver handle 1
Filler 5,5 lower end of the filler are connect with the hollow pipeline 4, and one piece of the rear end connection of the hollow pipeline 4 is circular
The upper surface of rare earth neodymium magnet steel 6, the rare earth neodymium magnet steel 6 is the poles N or the poles S, and the side of the rare earth neodymium magnet steel 6 connects one and turns over
Shaft 7,7 one end of the reversing shaft export 1 side wall of screwdriver handle, and the rear end both sides of the screwdriver handle 1 set accumulator tank 8,
