Abstract
The invention discloses an all-insulation screwdriver and relates to the technical field of electric tools. The all-insulation screwdriver comprises a screwdriver rod and a handle, the screwdriver rod comprises a rod body and a screwdriver head, the outer surface of the rod body is coated by a PC insulating sleeve, the screwdriver rod and the handle are movably connected in an inserting mode, a rotation prevention structure is arranged on the screwdriver rod, a first magnet is arranged at the inserting-connection end of the screwdriver rod, the outer surface of the handle is coated by a PC insulating sleeve, a second magnet is arranged at the bottom of a blind hole of the inserting-connection end of the handle, an insulating telescopic pipe is arranged on the outer side of the screwdriver head, the upper portion of the insulating telescopic pipe is connected with the PC insulating sleeve on the rod body, and the screwdriver head is located in the insulating telescopic pipe. The PC insulating sleeves coat the rod body and the handle respectively, the connection portion of the rod body and the handle can not easily touch a terminal so that interphase short circuit can be avoided, when the insulating telescopic pipe is connected, the screwdriver can be at an all-insulation state when being used, and the all-insulation screwdriver is simple in structure, low in manufacturing cost and good in safety performance.
Description
Technical field
The present invention relates to electrician's technical field of tools.
Background technology
At present, screwdriver is conventional electrician's instrument, and Insulating screw driver need to human body contact site on be laid with electric insulation layer.Carry out power-on serving, detection in the equipment such as electrical control cubicles, electric appliance box time, because the live terminal in equipment is a lot, between each terminal, spacing between terminal row is less, when the screwdriver dismounting forming by a this complete metallic rod and installation screw, when bit rotary screwdriver, very easily meet other adjacent live terminal, cause short circuit and ground fault to occur, jeopardize the safety of the person and equipment, very dangerous convenience in use.
Granted publication number is that the Chinese invention patent of CN201061871Y discloses a kind of Insulating screw driver, comprise handle, knife bar and cutter head, cutter head and knife bar are integral type, on described knife bar, be enclosed with the insulated plastic bed of material, handle is provided with jack, and knife bar plug type is arranged in jack, and described jack inwall is provided with elastic bumps, the insulated plastic bed of material of knife bar is provided with the detent suitable with elastic bumps, and described detent is stuck on elastic bumps.Handle and the cutter head split design of this invention by Insulating screw driver, can change cutter head easily, has the advantages that security performance is good, simple in structure, easy to use, high pressure that can resistance to 1000V.
Although the technical scheme of this patent of invention has solved the human body contact site electric insulation problem of screwdriver, has higher withstand voltage.But the knife bar of this Insulating screw driver and handle only position by an elastic bumps, for the high voltage bearing Insulating screw driver of need, still there is reliability deficiency in this location structure, there is certain potential safety hazard, and for the spacing between terminal row hour, electrical insulating property deficiency, easily cutter head touches live terminal, has the risk of short circuit.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, security performance is high, can dismantle and can not cause short circuit between the live terminal of narrow space, protection operating personnel do not come to harm all insulation screwdriver.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of all insulation screwdriver, comprise knife bar and handle, described knife bar comprises the body of rod and cutter head, described body of rod outer surface is coated with the polyester insulated cover of carbonic acid, described knife bar and handle are movable pegs graft, and be provided with anti-rotation structure, described knife bar inserted terminal is provided with the first magnet piece, described handle outer surface is coated with the polyester insulated cover of carbonic acid, the bottom of described handle inserted terminal blind hole is provided with the second magnet piece, described cutter head outside is provided with insulating telescopic pipe, described insulating telescopic pipe top is connected with the polyester insulated cover of carbonic acid on the described body of rod, described cutter head is positioned at described insulating telescopic pipe inside.
Compared with traditional Insulating screw driver, the present invention adopts the polyester insulated cover of carbonic acid that the body of rod and handle are all wrapped up to covering, in the use procedure of screwdriver rotary screw, thereby while making its connecting portion be not easy to touch binding post, can not cause phase fault, the strong magnet by knife bar and handle plugging position can be simply, convenient, firmly peg graft.
Preferably, described handle bottom is provided with the through hole for external active force bar.By making it increase torsion at the inner external active force bar of through hole, alleviate operating personnel's active force.
Preferably, the inserted terminal of described knife bar is polygonized structure, and it is polygonal blind hole that described handle inserted terminal is provided with the cross section suitable with described knife bar inserted terminal; Increase the frictional force between its knife bar and handle, be more firmly engaged togather.
Preferably, the described body of rod and cutter head are more than two, and cutter head is different size; Its knife bar and cutter head can be the multiple different specification sizes such as size, length, a word, cross and are conveniently applicable to operating environment separately.
The beneficial effect that adopts technique scheme to produce is: the present invention adopts the polyester insulated cover of carbonic acid that the body of rod and handle are all wrapped up to covering, in the use procedure of screwdriver rotary screw, thereby while making its connecting portion be not easy to touch binding post, can not cause phase fault.And connected insulating telescopic pipe can be the present invention in use in all insulation state, simple in structure, low cost of manufacture, security performance is good, can protect operating personnel not come to harm.
