Abstract

The utility model discloses a stripping tool for the electricity and communication line, in particular to a longitudinal cable cutter. The utility model comprises two support brackets respectively comprising a rolling wheel and a cutter sleeve arranged with a blade. Each cutter sleeve is arranged on the middle portion of each support bracket and the rolling wheels are connected with the front support bracket and the back support bracket of the cutter sleeve. The two support brackets are movably connected by a lead rod. The longitudinal cable cutter also comprises a clamping mechanism and a walking device. The present utility model has simple structure and convenient manufacture. The cable stripping is labor saving and time saving. The cutting is bidirectional and symmetrical type with rapid speed and thus the cutting depth can be conveniently adjusted. The utility model is suitable for the bidirectional stripping of the electricity and communication line of various styles and specifications and also the quality can be guaranteed.

Description

Vertical cable cutter

Technical field

The utility model discussion be a kind of stripping instrument of opening of cable, particularly a kind of instrument of vertically opening the wire stripping cable.

Technical background

Along with progress of science and technology; expanding economy; electric power, communication line almost spread all over each corner of motherland; often need carry out the connection of cable at laying electric power, communication line work progress; processing to cable also usually takes place in daily electric power, communication line maintenance work; because the protective layer of cable is thicker; generally open the wire stripping cable with knife by hand; the hidden danger that has safety and quality; and with the stripping instrument of opening of pliers type; more time-consuming taking a lot of work, and open the quality instability of shelling cable.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of convenient, fast reaching stably from vertically driving the instrument of wire stripping cable.

The vertical cable cutter of the utility model comprises two supports, and each support comprises: roller, the broach shell of blade is housed, broach shell is contained in the middle part of each support respectively, and roller is connected on the support of front and back of broach shell.Two stands flexibly connects with the helical pitch bar; During work, the blade of two stands is relative, and broach shell is concentricity, and four rolling is symmetry in twos.

The utility model also comprises clamp system, clamp system comprises ratchet bar, following ratchet bar, locating shaft, wing nut, last ratchet bar by and locating shaft on the support be connected, locating piece, time ratchet bar are placed in the ratchet slot of another support, locating piece is fixed in this ratchet slot, adjusting screw(rod) is connected with the outer end of following ratchet bar by wing nut, locating piece, spring, during work, left and right sides support closes up relatively, and upper and lower ratchet bar should be overlapping.

The utility model also comprises running gear, running gear comprises ratchet, handle, clutch, inner ring, interior cover, the clutch of each support is placed in the ratchet, inner ring is placed in the clutch, taper knob is outside ratchet, handle and ratchet place support below, by the riveting pipe with two eccentric adjusting knobs from a support right side, left two outsides fixedly connected with inner ring by interior cover, two ratchets on the two stands are corresponding.

The utility model is simple in structure, and is easy to make, not only time saving and energy saving when opening the wire stripping cable, and owing to be the bi-directional symmetrical feed, speed is fast, and depth of cut can conveniently be adjusted, and is suitable for that multiple different size, the electric power of kind, the communications cable are two-way opens stripping, and quality is secure.

Embodiment

Further specify specific implementation method of the present utility model in conjunction with Fig. 1-3: at first make two right left symmetrical supports 6 by the designing requirement die sinking, blade 7 usefulness screws are fixed on the broach shell 2, then with regulating bolt 8, packing ring I is connected with broach shell 2, then broach shell 2 is put into the broach shell hole 26 of each support 6 one side, use packing ring II again, nut 10 is connected with adjusting bolt 8 from the support opposite side, with stove bolt 27 nut 3 being regulated in feed at last is fixed on the adjusting bolt 8, two roller 5-1 are arranged on each support 6,5-2, before they are movably connected in broach shell 2, after, promptly broach shell 2 on, upper/lower positions.Last ratchet bar 14 is fixedlyed connected with the locating shaft 13 of a support upside, and following ratchet bar 15 is placed on another support upside, with last ratchet bar relevant position (ratchet slot 12 is arranged on the support).Locating piece 18 is fixed on down in the ratchet slot 12 of ratchet bar 15, and screw rod 16 passes through wing nut 11, locating piece 18, and spring 17 is connected with the outer end of following ratchet bar 15.Regulate wing nut 11 and can make down ratchet bar 15 12 li slips of ratchet slot at another support 6 upsides.When closing up relatively about two stands, upper and lower ratchet bar should be overlapping.The clutch 21 of each support is placed in the ratchet 19, inner ring 22 is placed in the clutch 21, then handle 20 is enclosed within outside the ratchet 19, handle 20 is fixedlyed connected with ratchet 19, and ratchet 19 is placed on the below of each support 6 inboard, is connected with inner ring 22 from each support 6 right side, left two outsides by interior cover I, II with two eccentric adjusting knobs 25 at last, pass the center of two eccentric adjusting knobs 25 then with riveting pipe 27, rivet, during work, the ratchet of two stands is relative.

During use; at first estimate the thickness of cable protection layer according to the external diameter of cable; cable is placed between the two stands; regulate the feed adjusting nut; fixedly the position of broach shell (promptly just making depth of cut); clamp system closes; pass on moving eccentric governor joint knob, just the serrated clips stringing cable surface of ratchet presses down handle simultaneously then simultaneously; the rotation of drive ratchet; cable is forwards sent, and the effect of roller is to reduce the resistance that cable moves, this moment blade from the both sides of cable with the strip off of cable protection layer; just can accomplish when opening the wire stripping cable so fast; joint power can guarantee the stable quality of opening wire stripping cable protection layer again.
