Abstract

The utility model discloses a novel convenient screw driver, which comprises a handle, a magnet conductive pipe, a magnet conductive iron, a permanent magnet, a moving contact head and a fixed contact head. The magnet conductive pipe is fixed inside the handle, the magnet conductive iron, the permanent magnet and the moving contact head are fixed together in sequence, and can be inserted into the magnet conductive pipe. The fixed contact head is made of high hardness soft magnetic material, and the operating point of the screw driver is adopted at the bottom end of the fixed contact head. The handle part between the moving contact head and the fixed contact head adopts a cavity, thereby the moving contact head can be pushed vertically, the screw driver can change the magnetism conveniently at any moment, the operation is simple and convenient, the structure is simple, and the cost is low.

Description

Novel convenient screwdriver

Technical field

The utility model relates to a kind of screwdriver, relates to a kind of novel convenient screwdriver of screwdriver application facet specifically.

Background technology

Existing screwdriver mainly divides two kinds on magnetic screwdriver and no magnetic screwdriver, and no magnetic screwdriver can't absorb screw; Though have the magnetic screwdriver to draw to screwdriver, when drawing because that screw is put direction is inaccurate, make put into screw after, can not immediately it be tightened, if mobile screwdriver can be taken screw out of again, make operation very big inconvenience occur like this, waste time and energy.After having the magnetic screwdriver to use a period of time simultaneously, magnetic can subtract greatly, need magnetize if will continue to use.Along with science and technology development, instrument and equipment is miniaturization or subminaturization gradually, therefore, the use of small-sized screwdriver more and more widely, operation also more and more needs to draw a kind ofly can change the novel screwdriver that magnetic has or not at any time.

Summary of the invention

It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and both can draw iron class screw, is convenient to put into the novel convenient screwdriver with tighten the screws again.

The utility model by handle, magnetic conductive tube, magnetic conduction iron, permanent magnet, moving contact head, decide contact head (making) and form by the high rigidity soft magnetic materials, magnetic conductive tube is fixed on handle inside, magnetic conduction iron, permanent magnet, moving contact head are fixed together in order, and in the insertion magnetic conductive tube, one side of moving contact head leans out a dop, can be used for promoting up and down moving contact head.The inner moving contact head of handle is a cavity with deciding the contact head mid portion.

The convenient screwdriver of the utility model pushes away on dop when using, and makes contact head and decides contact head and separate, magnetic conduction iron, permanent magnet insert in the magnetic conductive tube, make the magnetic circuit closure of permanent magnet, decide the contact head part like this and do not show magnetic, this screwdriver makes can not have the use of magnetic screwdriver; When pushing away with under the dop, contact head is engaged with deciding contact head, permanent magnet is transferred to magnetic conductive tube, and the magnetic circuit of permanent magnet is opened, and magnetic makes and decides the apparent magnetic of contact head in conjunction with deciding contact head, and this screwdriver just can have been made the magnetic screwdriver and use.

Below in conjunction with the drawings and specific embodiments the utility model is described in further details:

Fig. 1 is the structural representation of the convenient screwdriver of the utility model

The specific embodiment

This novel convenient screwdriver is that magnetic conductive tube (2) is fixed on handle (1) inside, decide contact head (6) and be fixed on handle (1) interior forward end, simultaneously magnetic conduction iron (3) permanent magnet (4) and moving contact head (5) are pressed as the figure fixed order together, and insert in the magnetic conductive tube (2), moving contact head (5) handle (1) interior section middle with deciding contact head (6) is cavity, lean out a dop in a side of moving contact head (5) and promote moving contact head (5) before and after being used for so that moving contact head (5) with decide contact head (6) and contact or separate.

Claims

1. novel convenient screwdriver, comprise handle (1), magnetic conductive tube (2), magnetic conduction iron (3), permanent magnet (4), moving contact head (5), decide contact head (6), it is characterized in that, magnetic conductive tube (2) is fixed in handle inside, magnetic conduction iron (3), permanent magnet (4), moving contact head (5) are fixed together in regular turn, and can insert magnetic conductive tube (2), decide contact head (6), make by the high rigidity soft magnetic materials, its bottom is the screwdriver operating point, moving contact head (5) and handle (1) part of deciding between the contact head (6) are cavity, and contact head (5) can be promoted up and down.
