Abstract

The utility model relates to a self-locking adjustable wrench of a pipe wrench, which is composed of a main clamping tongue, a guiding clamping tongue, a gear position pin, an operating handle, etc., wherein, the main clamping tongue is provided with a wrench handle and a shrapnel. The self-locking adjustable wrench of pipe wrench combines the functions of an adjustable wrench, a pipe wrench and a wire cutter into integration and has the advantages of simple structure, low cost, multifunction, economical use and convenient carryover and storage; the utility model can be used conveniently for rotating work pieces continuously without withdrawing the wrench and changing places.

Description

A kind of self-locking Pipe-tongs adjustable spanner

The utility model relates to screwing or unscrewing of a kind of turret head that is directly used in certain limit commonly used and square head bolt, nut, the turn of metal tube or other cylindrical work and clamping, the fractureing or the manual tool of cut-out wiry of sheet metal.

At present, turn bolt, nut, metal tube or other round piece and clamping or the sheet metal that fractures cut off wire, need use monkey wrench respectively, series of tools such as pipe vice and cutting pliers, these tool producing process complexity can not one-object-many-purposes, the integrated cost height, not only uneconomical but also be not easy to keeping, use also inconvenient.

The purpose of this utility model is to avoid the described weak point in the background technology, and provide a kind of simple in structure, the function that integrates instruments such as monkey wrench, pipe vice, cutting pliers, the energy one-object-many-purposes, cost is low, not only economy but also be easy to carry and take care of self-locking Pipe-tongs adjustable spanner extremely easy to use.

The purpose of this utility model realizes by following approach: there is V-shaped groove at this self-locking Pipe-tongs adjustable spanner one side middle part, the bottom have laterally vertical circular hole and the one side middle part on the major blocked tongue of chopping mouth have with major blocked tongue on the corresponding V-shaped groove of V-shaped groove, the V-shaped groove back side is the guiding block tongue connection of circular arc sawtooth.One end of major blocked tongue has the pincers handle that fuses, and the other end has fixing shell fragment.The vertical circular hole of gear pin on major blocked tongue connects working handle, and working handle is connected with gear forms with the guiding block tongue.Gear pin one end that connects working handle has open slot, and setting-in annular gasket in the open slot is equipped with spring in the center hole of open slot, and spring is fixed through hold-down screw, and the gear pin is located through alignment pin.

The utility model compared with prior art has following characteristics: simple in structure, cost is low, the function that has monkey wrench, pipe vice and cutting pliers simultaneously, the energy one-object-many-purposes, not only economy but also be easy to carry and take care of, the turn workpiece can carry out continuously, need not extract spanner out and change the position, uses very convenient.

Fig. 1 is the utility model self-locking Pipe-tongs adjustable spanner schematic diagram.

Fig. 2 is the utility model self-locking Pipe-tongs adjustable spanner gear pin schematic diagram.

Fig. 3 is that gear pin A of the present utility model is to schematic diagram.

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in Figure 1, a kind of self-locking Pipe-tongs adjustable spanner of the present utility model, the one side on the major blocked tongue (1) has V-type groove (7), and there is chopping mouth (6) below, and guiding block tongue (2) is sleeved in the laterally vertical circular hole on the major blocked tongue (1).One end of major blocked tongue (1) is equipped with the pincers handle (5) that fuses, and the other end is fixed with shell fragment (9), and gear pin (3) connects working handle (4) by the vertical circular hole on the major blocked tongue (1).Be fixed on the shell fragment (9) on the major blocked tongue (1), do the activity that resets for working handle (4).Pincers handles (5) are parallel with working handle (4) to play afterburning acting on.There is the corresponding V-shaped groove (7) of V-shaped groove (7) with major blocked tongue (1) middle part at guiding block tongue (2) one side middle part, and the back side of V-shaped groove (7) is circular arc sawtooth (8), and guiding block tongue (2) is connected with gear forms with working handle (4).The block tongue (2) that will lead transfers the turnback suit to go in the laterally vertical circular hole of major blocked tongue (1), can make pipe vice and use.

Shown in Fig. 1～3, a kind of self-locking Pipe-tongs adjustable spanner of the present utility model, gear pin (3) one ends that connect major blocked tongue (1) and working handle (4) have open slot (14), setting-in annular gasket (12) in open slot (14), spring (13) is housed in the center hole of open slot (14), and fixing by hold-down screw (10), gear pin (3) is located through alignment pin (11).
