Description
The utility model is called the wire stripping screwdriver, and it is a kind of electric hand-tool.
In the electrical installation, regular work is the outer insulating barrier of stripping electric wire.Wire stripper are wire stripping hand-held tools of domestic unique special use at present, and it is easy to use, but it is the most complicated hand welding of structure, heavy, the very much not portable band of volume.In the routine work, pincers such as people's nipper plier commonly used replace wire stripper, also sting wire stripping with tooth sometimes.The edge of a knife up and down of nipper plier etc. is straight line, blunt mouth, so can not cut off the insulating barrier outside the lead simultaneously on whole circumference.Wire stripping effort like this, inconvenience be damage wires easily again, has illustrated also that on the other hand to peel off the required cutting force of insulating barrier very little.Screwdriver is one of the most frequently used hand tools.People have adorned voltage test pencil on small screw driver, enlarged its function.The purpose of this utility model is that the function with wire stripper is attached on the screwdriver, produces a kind ofly can shell the multiple diameter electric wire effortlessly, light portative novel screwdriver.
Fig. 1 represents to prepare the stripping electric wire.The utility model is that the wire stripper of chopper type is embedded on the cylindrical of screwdriver handle vertically.Several different-diameter semicircle edges of a knife are respectively arranged in the bottom knife on the chopper, and chopper is fashionable, and the edge of a knife is synthetic circular up and down.During wire stripping, the right hand holds on screwdriver handle, and thumb opens chopper, and left hand is put into the edge of a knife identical with diameter of wire with electric wire; Right hand thumb cuts off insulating barrier by pressing chopper; Left hand and right hand is oppositely separated, and insulating barrier promptly comes off from lead.
The utility model great advantage is that it has the repertoire of screwdriver and wire stripper, carries again easily.It is more convenient, laborsaving than wire strippings such as use nipper pliers, not damage wires; It is simple in structure, and is easily manufactured, and cost is lower than wire stripper.
Fig. 2 goes up the lower slide enlarged drawing.The cylindrical of wood screw handle of a knife (1) is opened a groove that the cross section is about 5 * 5 millimeters vertically, and screw is fixed in the groove of handle (1) by hole (2) lower slide (3) with plastics, perhaps sticks with glue in groove.Bottom knife (4) is embedded in the lower slide (3), and its left end (5) becomes spring-like, and there are several different-diameter semicircle edges of a knife at the middle part.Handle (1) correspondingly has some translots (6), and electric wire (7) is absorbed in the groove (6), can not horizontally slip during wire stripping.Upper tool post (8) leans on axle (9) hinge-coupled to become the wire stripper (14) of chopper shape with lower slide (3).(15) be cutter, (16) are screwdriver rods.Upper tool post top is widened, and is convenient to thumb and pushes and increase the upper tool post mechanical strength.When the edge of a knife healed up up and down, protruded in the outside of handle (1) cylindrical on upper tool post (8) top, and insert in the corresponding groove of lower slide (10) bottom.Bottom knife left end spring (5) and cutter left end (11) match.Require: when last lower slide angle α angle less than α
1During the angle, spring force makes α angle trend zero; When the α angle greater than α
1During the angle, α angle trend α
2The angle; α angle perseverance is not more than α
2The angle.The utility model wire stripping operation principle is when last bottom knife angle of cut α angle trend is zero, to cut off insulating barrier.
Last bottom knife can be designed to the shape of (12), (13) locate mode, make electric wire more reliably frame on the following edge of a knife, wait to be cut.Bottom knife can directly be embedded in the screwdriver handle of plastics matter, has saved lower slide (3).
Claims (1)
1, a kind of wire stripping screwdriver is made up of screwdriver handle (1) and screwdriver rod (16), it is characterized in that studding with vertically on the cylindrical of screwdriver handle (1) wire stripper (14) of chopper shape, and its cutter (15) and bottom knife (4) have the edge of a knife of different-diameter.
