Description

Multifunctional wrench Technical Field The utility model relates to the technical field of wrenches, in particular to a multifunctional wrench. Background In the process of machine manufacturing, assembly and maintenance, the spanner is the very high instrument of frequency of use, in the mechanical maintenance operation, the machine of decocting medicinal herbs, packagine machine inner space is narrow, and traditional spanner's operating space is limited, is difficult to screw up or dismantle the operation to nut or bolt that is in special position in a flexible way, and conventional spanner can't go deep into narrow and small gap and carry out the operation, leads to narrow space to tear out the piece difficultly, is difficult to satisfy diversified maintenance needs for maintenance work becomes loaded down with trivial details and consuming time. Disclosure of utility model The utility model aims to provide a multifunctional wrench which has the advantages of multiple functions and convenience in disassembly in a narrow space. In order to achieve the purpose, the multifunctional wrench comprises a threaded rod, wherein an auxiliary nut is sleeved on an external thread at the left end of the threaded rod, a main screw nut is sleeved on a right side thread of the auxiliary nut, a threaded sleeve is sleeved on the outer portion of the right end of the threaded rod, an adjusting screw is connected to the internal thread of the threaded sleeve, and a rotating handle is fixedly arranged in the middle of the right end of the adjusting screw. As the preferable scheme, the outside welding of main screw nut has the connecting rod, the right-hand member welding of connecting rod has the rotation disc, the rotation disc cup joints in screw sleeve's outside and rotates the installation. As the preferable scheme, the left end of threaded rod is located between vice nut and the main screw nut and has cup jointed adjusting nut, adjusting nut's right side is flat setting. As a preferable scheme, the external thread at the right end of the adjusting screw rod is sleeved with a fastening nut, and the left end of the fastening nut is fastened and connected with the right end of the threaded sleeve. As an optimized scheme, the main screw nut, the rotating disc and the connecting rod are integrally designed, and the rotating disc and the threaded sleeve relatively rotate. Compared with the prior art, the utility model has the following beneficial effects: 1. According to the wrench, the mode of threaded sleeving and threaded connection is adopted, looseness among all parts can be effectively prevented in the using process of the wrench, stability of the wrench when the nut and the bolt are screwed or disassembled is guaranteed, misoperation and potential safety hazards caused by looseness of the parts are reduced, all the parts are mutually matched to form an organic whole, a threaded rod is used as a core part, a supporting and connecting foundation is provided for other parts, parts can be disassembled in a narrow space, and a better clamping screw can be disassembled. 2. According to the utility model, finer adjustment can be realized through the adjusting nut, after the auxiliary nut and the main screw nut are subjected to preliminary large-scale adjustment, fine size adjustment can be performed through rotating the adjusting nut, and the friction force between the right flat type adjusting nut and the contact part is increased, so that the adjusting process is more stable, and loosening or sliding in the adjusting process can be effectively avoided.
