Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a universal adjusting wrench according to an embodiment of the present invention. A universal adjusting wrench according to a preferred embodiment of the present invention includes a wrench head portion 1, a long nut 2, a locking nut 3, a screw portion 4, a rotation portion 5, a chain portion 6, a transition portion 7, a link portion 8, and a grip portion 9.
In some embodiments, the wrench head 1 includes a plate opening portion for fastening a nut or a bolt, and an adjustment portion capable of adjusting the size of the plate opening portion. One end of the long nut 2 is fixedly connected with the tail end of the wrench head part 1; one end of the screw rod part 4 is screwed into the other end of the long nut 2; the locking nut 3 is locked on the long nut 2 in a rotating mode and is located between the long nut 2 and the rotating part 5; the rotating part 5 is fixedly connected with the other end of the screw part 4, and the rotating part 5 can drive the screw part 4 to screw in or screw out the long nut 2; one end of the chain part 6 is fixedly connected with the rotating part 5; the connecting rod part 8 is arranged between the transition part 7 and the handle part 9, one end of the connecting rod part is fixedly connected with the transition part 7, and the other end of the connecting rod part is fixedly connected with the handle part 9.
In some embodiments, the surface of the grip portion 9 is provided with knurling, and the grip portion 9 is made of a non-metallic material having elasticity, such as rubber, plastic, or a combination of the two.
The manufacturing process of the universal adjusting wrench comprises the following steps: firstly, cutting a wrench head part 1 of a common movable plate, welding a long nut 2 at the tail end of the wrench head part, cutting a section of screw rod part 4 matched with the thread of the long nut 2, screwing a corresponding nut at one end of the screw rod part 4, welding the nut and the screw rod part 4 to be dead, then welding a nut on the nut in a superposed manner, then cutting a section of chain on the nut welded later to be used as a chain part 6, welding one end of the chain together all the time, welding the other end of the chain to be a transition part 7 formed by overlapping two nuts together, cutting off the head part by selecting a screwdriver, only leaving a cutter bar and a handle part 9, and welding the cutter bar serving as a connecting rod and the transition part 7 together; and screwing a nut on the screw rod part as a locking nut, screwing one end of the screw rod part into the long nut, and locking the long nut by using the locking nut to finish the manufacture of the universal adjusting wrench.
