Description
Technical field
Screwdriver bit technical field is the utility model is related to, relates in particular to a kind of magnetosphere screwdriver bit.
Background technology
Screwdriver bit, it is often referred to be installed to the driver bit of the turn of the screw above electric hand drill or electric hammer.Magnetosphere screwdriver bit is a kind of band
The screwdriver bit of magnetosphere, as Patent No. CN2015209644409 Chinese patent provides for a kind of magnetosphere screwdriver bit, in original screw
The head of screwdriver bit has added a magnetosphere, and it is weak to solve original screwdriver bit magnetic itself, it is difficult to the problem of strong adsorption long screw；The magnetic
Circle screwdriver bit includes work department, has added one of spring inside it, has made have certain bit space that allows before and after magnetosphere, solve magnetosphere and fix
The screw cross recess brought it is deep mixed, make screwdriver bit insert depth difference the defects of.But the magnetosphere of above-mentioned prior art
The following two kinds defect also be present in screwdriver bit：
1st, the work department of the magnetosphere screwdriver bit, connecting portion and clamping part are structure as a whole, non-dismountable, and the part adds
The diameter of screwdriver bit, some positions are caused to use.
2nd, because the screwdriver bit uses spring return, and spring is magnetic conductive component, may result in magnetic force
It is scattered, and spring is iron piece, and screwdriver bit is also iron piece, mutual abrasion therebetween or the service life that above-mentioned part can be caused
Shorten；
3rd, magnetosphere and screwdriver bit there are gap, cause magnetosphere and screwdriver bit decentraction, and when resetting, magnetosphere may be because deviation
Screwdriver bit center and cause to be unable to normal reset, influence the use of magnetosphere screwdriver bit.
Utility model content
The defects of the purpose of this utility model is to be directed to above-mentioned prior art, there is provided a kind of magnetosphere screwdriver bit, the magnetosphere batch
Head is split-type structural, and its centering is good, is advantageous to the reset of magnetosphere, ensures the normal use of magnetosphere screwdriver bit；And damaged without magnetic force
Lose, and reduce mutual abrasion.
To achieve these goals, the technical solution of the utility model is：
A kind of magnetosphere screwdriver bit, including clamping part, connecting portion and work department, the clamping part, connecting portion are connected one
Structure, the work department are ring-type and are sleeved on connecting portion that the work department sets one end open, the blind slot of one end closing,
The front end of the blind slot, the work department set groove and connected with blind slot, be provided with the groove corresponding with the groove
Magnetosphere；Elastic component made of polyurethane is set in the blind slot；The work department is circumferentially provided with spiral shell rear end and front end
Hole, the magnetosphere are provided with the through hole of Long Circle in relevant position, and the screw is provided with set screw；The head of the connecting portion
Portion is work head, and screw cross recess is set on the work head.
As the improvement to above-mentioned technical proposal, the work department is respectively one group in the screw of rear end and the screw of front end,
Each group of screw is two, is symmetrical arranged, the line of centres of two groups of screws is perpendicular.
As the improvement to above-mentioned technical proposal, the work department is cylinder.
As the improvement to above-mentioned technical proposal, the set screw is less than the outer surface of work department, the regulation spiral shell
The outer concave end of silk has neck, in this way, depth of the set screw in work department, adjustment work portion can be adjusted by screwdriver
Centering.
Compared with prior art, the utility model has the advantages and positive effects of：
Magnetosphere screwdriver bit of the present utility model, 1, this magnetosphere screwdriver bit be demountable structure, work department can take from connecting portion
Under, in the less occasion in space, the magnetosphere screwdriver bit, which can have, makees common screwdriver bit；2nd, because making flexible member using polyurethane, because
This, can be avoided the abrasion of connecting portion 2, extend the service life of screwdriver bit；Polyurethane is non-magnetic element, can avoid magnetic force
Loss.3rd, set screw with adjustment work portion and the centering of connecting portion, can ensure the axiality of two parts, in resigning and again
During position, it is ensured that the normal reset of work department, ensure the normal use of magnetosphere screwdriver bit.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
