Abstract
The invention discloses a high pressure resistant screwdriver, which comprises a cutter bar and a handle, wherein the handle is arranged at the tail part of the cutter bar; the cutter bar is provided with an insulation sleeve; the handle and the insulation sleeve are made of an insulation flame retardant material; the surface of the handle is at least provided with a standstill locking plane; the front part of the handle is provided with a front anti-skidding area which is provided with a plurality of rubbing strips; the rear part of the handle is provided with a plurality of rear anti-skidding areas which are provided with a plurality of anti-skidding lugs; and the rear end of the handle is provided with suspension through holes which are radially distributed. By using the handle and the insulation sleeve which are made of the insulation flame retardant material, the withstand voltage of the screwdriver can be up to 1000V, and the screwdriver has fireproof performance and is safer. The handle is provided with a plurality of anti-skidding lugs and the part on which the thumb applies force is provided with the rubbing strips, thereby enabling the screwdriver to better apply force during using; and the surface of the handle is at least provided with a standstill locking surface, thereby enabling the screwdriver not to roll randomly after being placed.
Description
Technical field
The present invention relates to a kind of hardware ﹠ tools, relate in particular to a kind of high pressure resistant screwdriver.
Background technology
The normal screws cutter comprises: handle, be arranged on knife bar on the handle, be arranged on the cutter head on the knife bar.These usually feel application of force difficulty when screwdriver turns the bigger screw of resistance, long exposed knife bar is comparatively dangerous when being used for the installing/dismounting of appliance circuit, and using the gap often to be rolled at a distance, brings inconvenience to the user.
Summary of the invention
Technical problem to be solved by this invention is: a kind of high pressure resistant screwdriver of being convenient to the application of force is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of high pressure resistant screwdriver comprises: knife bar, be arranged on the handle of knife bar afterbody, described knife bar is provided with insulation sleeve, and described handle and insulation sleeve are made by the insulation fire proofing.Described handle surfaces is provided with a spline plane at least.Described handle front portion is provided with preceding skid-proof regions, and preceding skid-proof regions is provided with some friction bars.Described handle rear portion is provided with some backs skid-proof regions, is provided with several anti-skidding projections in the back skid-proof regions.The rear end of described handle is provided with the suspension through hole of radial arrangement.
Advantage of the present invention is: owing to adopted the insulation fire proofing to make handle and insulation sleeve, make the withstand voltage 1000V of reaching of screwdriver, and have fire protecting performance, use safer.Owing to be provided with some anti-skidding projections and be provided with the friction bar, make the screwdriver in use can better the application of force in the thumb force part at handle portion.Because handle surfaces is provided with a spline plane at least, after being placed, screwdriver can arbitrarily not roll.
Description of drawings
Fig. 1 looks schematic diagram for master of the present invention.
Among the figure: 1. knife bar, 2. handle, 3. before skid-proof regions, 4. fricting strip, 5. spline plane, 6. back skid-proof regions, 7. anti-skidding projection, 8. insulation sleeve 9. hangs through hole.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of high pressure resistant screwdriver comprises: knife bar 1, be arranged on the handle 2 of knife bar 1 afterbody, described knife bar 1 is provided with insulation sleeve 8, and described handle 1 is made by the insulation fire proofing with insulation sleeve 8.Described handle 2 surfaces are provided with a spline plane 6 at least.Described handle 2 front portions are provided with preceding skid-proof regions 3, and preceding skid-proof regions 3 is provided with some friction bars 4.Described handle 2 rear portions are provided with some backs skid-proof regions 6, are provided with several anti-skidding projections 7 in the back skid-proof regions 6.The rear end of described handle 2 is provided with the suspension through hole 9 of radial arrangement.
Owing to adopted the insulation fire proofing to make handle 2 and insulation sleeve 8, make the withstand voltage 1000V of reaching of this high pressure resistant screwdriver, and have fire protecting performance, use safer.Owing to be provided with some anti-skidding projections 7 and be provided with friction bar 4 in the thumb force part, make the screwdriver in use can better the application of force in handle 2 parts.Because handle 2 surfaces are provided with a spline plane 5 at least, after being placed, screwdriver can arbitrarily not roll.Because knife bar 1 is provided with insulation sleeve 8, makes screwdriver safer when being used for the installing/dismounting of appliance circuit.
