TECHNICAL FIELD

[0001] The utility model relates to the technical field of pliers, and particularly relates to a locking pliers with a wrench function. BACKGROUND

[0002] The locking pliers generally comprise a fixed jaw, a movable jaw, a movable handle, a fixed handle, an adjusting bolt, a support plate, a quick-release handle, a tension spring, and a rivet. The fixed jaw and the fixed handle are fixed together by welding. One end of the support plate is connected to the movable jaw by a rivet, and the other end of the support plate is in contact with the bottom of the adjusting bolt. The position of the support plate is adjusted by adjusting the position of the adjusting bolt, so that the opening size of the locking pliers is adjusted.

[0003] The locking pliers are commonly used hand tools, which are widely used in woodworking, metalworking, and welding fields. The locking pliers are mainly used for clamping parts for welding, riveting, and other machining processes. The locking pliers play an important role in the machining and maintenance processes. In daily work, wrenches are also widely used. However, the existing wrenches have too many specifications and single functions. When used, the corresponding wrenches need to be replaced constantly. In addition, the overall length of the wrenches is relatively long. When placed in a worker's tool bag, the wrenches are heavy and not flexible. When used, it is difficult to quickly find the corresponding tool, which causes difficulties in carrying and using. Therefore, simplifying the tools has become a problem to be solved at the present stage. SUMMARY

[0004] The utility model provides a locking pliers with a wrench function to solve the problem of too many types of tools and inconvenience in carrying and using.

[0005] To solve the above problems, the utility model provides the following scheme: a locking pliers with a wrench function, which comprises a fixed handle, a movable handle, a fixed jaw, a movable jaw, a quick-release handle, an adjusting bolt, a tension spring, and a support plate. The movable jaw is arranged in cooperation with the fixed jaw. One end of the movable jaw is connected to the movable handle by a rivet. One end of the movable jaw is connected to the fixed handle by a rivet and a tension spring. The fixed jaw is fixed to one end of the fixed handle. One end of the support plate is connected to the movable handle by a rivet. One end of the movable handle is equipped with the quick-release handle. The other end of the support plate is in contact with the bottom of the adjusting bolt. One end of the fixed handle is equipped with the adjusting bolt by screwing.

[0006] One end of the adjusting bolt is a threaded column, and the other end is a wrench part. The wrench part is provided with a working surface A and a working surface B. The working range of the working surface A and the working surface B gradually decreases from inside to outside. The working surface A and the working surface B are provided with equally spaced sawtooth structures. The working surface A and the working surface B are connected to form a clamping space for placing different types of clamped objects. The clamping space is provided with a plurality of clamping sites, which can be used for disassembling different types of clamped objects.

[0007] The utility model discloses have the following beneficial effects with the above scheme:

[0008] The utility model discloses the wrench of big force has the function of open wrench, plum blossom wrench and so on, and is suitable for the dismounting of nut or bolt of various specifications, such as hexagon nut, butterfly nut, round nut etc.

[0009] The utility model discloses the sawtooth structure on the working surface has, when being contacted with the clamped object, increase the friction of the clamped object, make the clamped object not easy to slip, can better dismount bolt, nut.

[0010] The utility model discloses the adjusting bolt, shape flat, still can easily fine tune adjusting bolt under the condition that the hand has oil dirt or sweat mark, change the position of support board, adjust the opening size of big force pliers, through adjusting bolt can also be received to multifunctional wrench, reduce the space occupation, avoid the accumulation of various tools, increase the difficulty of finding.
