Abstract

The utility model relates to a pair of long flat nose pliers with wire stripping function. The utility model is characterized in that the width between the plier point and the plier mouth of the long flat nose pliers is increased, and an A blade and a B blade movable knife blades are arranged between the plier point and the plier mouth of the long flat nose pliers. The A blade and the B blade are fixed on two plier blades by bolts and form a set of wire stripping mouths which comprises two sets of movable knife blades, and the scope of the wire stripping bore diameter is between 0.6 and 6.4. The utility model collects the functions of a pair of long flat nose pliers, a pair of wire stripping pliers and a pair of pricking pliers, and the wire stripping diameter is increased from four or five grades to night or nine grades. After the wire stripping mouth is blunt, and the wire stripping mouth is easily made, can be repeatedly replaced and then used, thus reducing the weight for carrying tools for an electrician, and the utility model can conveniently and safely finish the work of peeling wire heads or connecting the wires in the middle in the condition that electricity is on or off.

Description

Long flat nose pliers

The utility model belongs to electrician's hand tool.

In electrical field, the most frequently used and maximum hand tool of consumption of secondary line electrician is nipper pliers, wire stripping pliers etc.Existing wire stripping pliers exist complex structure, purposes is single, but wire stripping is directly few, yielding, thereby influence result of use and scope, generally can only divest the stripping of cutting of lead middle part, the insulating barrier of conductor wire end head and little line footpath insulating barrier, then powerless to the insulating barrier that divests on big line footpath lead and the circuit, finishing wire stripping and wiring needs just can finish with wire stripping pliers and nipper pliers, causes and carries inconvenience and trivial operations.In 90 11 14 CN2065536U, announced a kind of electrician's pliers of using more, though have point, flat mouth, tiger and wire stripping function, but because the wire stripping mouth is arranged on the pincers handle near the pincers axle head, cause the wire stripping one-stop operation to live wire to need a pincers sheet handle is striden into and withdraws from just and can finish, the result increases the danger of getting an electric shock, and is fixed because of the wire stripping mouth again, low precision, the rapid wear lead, the ground difficulty is in case the wire stripping mouth damages the function of just losing wire stripping.

The purpose of this utility model is to overcome the deficiency of existing nipper pliers and wire stripping pliers and provides a kind of and be made up of two groups of movable blades, nipper pliers with 4～9 class wire stripping mouth functions, easily grind repeated use after the wire stripping mouth is blunt, utilize pincers just can finish the insulating barrier of peelling off lead, carry out that lead connects and the line joint crimping is finalized the design, satisfy the needs of the charged and not live line working of low-voltage line electrician substantially.

The technical solution of the utility model is following realization, movable blade is installed between the pincers point of nipper pliers and jaw, blade is made up of A sheet and B sheet again, set bolt is fixed on the A sheet of the blade of activity and B sheet on the two pincers sheets by the bolt hole on the blade becomes one group of wire stripping mouth, the blade that this wire stripping mouth is two groups of activities is formed, the wire stripping pore diameter range of wire stripping mouth is φ 0.6～φ 6.4, and movable blade and wire stripping mouth grind with tool steel or high-speed tool steel disc and form.

The utility model and existing nipper pliers are compared the advantage that is had with wire stripping pliers be that Ji Jianzui, wire stripping, cold bundle function are one, one pincers to be used, but 8～9 class are brought up to by 4～5 class in the wire stripping footpath, the wire stripping mouth adopts movable blades, easily grind repeated use after blunt, the power supply worker is charged or not charged to finish that the end of a thread stripping connects or line stage casing wire stripping T connects, and alleviates the electrician and carries instrument weight, easy to use, safety simple to operate.

Accompanying drawing of the present utility model and drawing are described as follows:

Fig. 1. be the structural representation that the nipper pliers of wire stripping function is arranged.

Fig. 2. be the structural representation of blade (1).

Blade among the figure (1), pincers point (2), set bolt (3), wire stripping mouth (4), jaw (5), pincers axle (6), cold tying (7), glue are (8) and bolt hole (9).

Specific embodiment of the utility model is: the material of making each physical dimension that clamps sheet and use is substantially with conventional nipper pliers, but increase pincers points (2) to the length and width degree between the pincers axles (6), be shaped on the cold tying (7) of half near pincers axles (6) end at the pincers handle, the length and width part that between jaw (5) and pincers points (2), increases, mill out the groove that blade (1) can be installed, bore two in φ 4 holes and tapping, tool steel with 22 * 15 * 2 or high-speed tool steel disc, one end bores 4 two bolts hole of φ (9), the other end grinds into wire stripping mouth (4), the wire stripping hole semi arch scope of two groups of blades (1) is the A sheet of R0.30～R3.2, on another pincers sheet, make the B sheet with the method co-located, and make wire stripping mouth (4) fit in two groups of movable blades (1) that the wire stripping pore diameter range is φ 0.6～φ 6.4, set bolt (3) with 4 φ 4, be fixed on the two pincers sheets by the A sheet and the B sheet of the bolt hole (9) on the blade (1) the blade (1) of activity, with pincers axles (6) two pincers sheets are connected, and clamp the sheet sleeves two and go into the plastic insulation glue of withstand voltage 500V (8), promptly make the nipper pliers that this has the wire stripping function, the blunt back of wire stripping mouth (4) or when being used to divest the insulating barrier in collinear footpath is not unloaded set bolt (3) and is ground refitting and go up or install another group blade (1) and can realize.

Claims

1, a kind of nipper pliers that the wire stripping function is arranged, by blade (1), pincers point (2), set bolt (3), wire stripping mouth (4), jaw (5), pincers axle (6), cold tying (7), glue (8) and bolt hole (9) are formed, it is characterized in that: movable blade (1) is installed between pincers points (2) and jaw (5), blade (1) is made up of A sheet and B sheet, and set bolt (3) is fixed on the A sheet of the blade (1) of activity and B sheet on the two pincers sheets by the bolt hole on the blade (1) becomes one group of wire stripping mouth (4).
