Specific embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined goal of the invention taken, below
With reference to attached drawing and preferred embodiment, to according to the utility model proposes the specific embodiment of driver magnetic force sleeve, structure, spy
Sign and its effect are described in detail as after.
As shown in Figures 1 to 8, mainly included according to the exemplary driver magnetic force sleeve of the utility model：11 He of sleeve body
Magnetic bushing 12.For sleeve body 11 for being sheathed on outside driver, which can be cylindrical shape, have axially through
Endoporus；Optionally, sleeve body 11 can be metalwork.The rotating tool head 20 of the driver can be with the fastening of such as bolt, screw
The head of part 30 is mutually engaged, wherein, can be integral or separable between the rotating tool head 20 and the body of driver
's.Magnetic bushing 12 is arranged on the end of axial one end of sleeve body 11, is equipped with and 11 endoporus of sleeve body in magnetic bushing 12
It communicates and for the axially extending bore that passes through of rotating tool head 20 of driver.The end face towards place end of magnetic bushing 12 is formed with recessed
Slot, for the axially extending bore of magnetic bushing 12 through the groove, which is used to accommodate at least a portion and fastener of rotating tool head 20
At least a portion on 30 head, so that rotating tool head 20 is mutually twisted with 30 head of fastener in the groove.The groove
Inner wall is configured to the shape contacted with 30 head surface face of fastener, to enhance the suction to fastener 30, ensures to inhale
Attached stability.
At least a portion of the inner wall of 11 endoporus of sleeve body is in close contact with driver, and can be connected by being interference fitted.
Further, magnetic bushing 12 can be embedded in sleeve body 11, be equipped in sleeve body 11 and be arranged at intervals with end
