Abstract

The utility model discloses a rapid self-locking adjustable pipe wrench, which is composed of a main clamping tongue, a guide clamping tongue, a blocking pin, a working handle, etc. The main clamping tongue is provided with a handle and a spring piece. The rapid self-locking adjustable pipe wrench integrates the functions of adjustable spanners, grip wrenches and cutting pliers. The utility model has the advantages of simple structure, low cost, one object with multifunction, convenient operation, convenient custody, money saving and portability. The rapid self-locking adjustable pipe wrench can rotate the work piece continuously without changing the position by reeling off wrenches.

Description

Rapid self-locking adjustable pipe wrench

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 above-described weak point in the prior art, and provide a kind of simple in structure, integrate the function of 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 fast self-locking formula Pipe-tongs adjustable spanner extremely easy to use.

The purpose of this utility model realizes by following approach: there is V-shaped groove at the 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 connection work handle of gear pin on major blocked tongue, the work handle is connected with gear forms with the guiding block tongue.Gear pin one end of connection work 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 embodiment of fast self-locking formula Pipe-tongs adjustable spanner of the present utility model in conjunction with the accompanying drawings is described in further detail.

Fig. 3 gear pin A is to schematic diagram

As described in Figure 1, fast self-locking formula 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) is by the vertical circular hole connection work handle (4) 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 work handle (4).Pincers handles (5) are parallel with work 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 work 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, fast self-locking formula Pipe-tongs adjustable spanner of the present utility model, gear pin (3) one ends that connect major blocked tongue (1) and work 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).

The utility model has following characteristics compared to existing technology: simple in structure, cost is low, has simultaneously monkey wrench, the function of pipe vice and cutting pliers can 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.
