The invention comprises a nut, an upper opening of the nut connected to a cover plate, and a lower opening of the cover plate connected to a protrusion disposed above the inner side of the nut. The advantage is that the nut can be threadedly connected to the stud bolt. Once the stud bolt is tightened, the top of the stud bolt presses against the protrusion, resulting in a small force-bearing area. The nut can be easily withdrawn without damaging the threads of the stud bolt.

[0004] Based on the above patent, most of the wrenches used for stud bolts in the prior art are of an integrated structure. When the stud bolts are tightened, the contact parts of the tool jaws are prone to wear. Over time, when the wear reaches a certain level, the wrench cannot be used anymore, causing the wrench material to be recycled as waste. However, the wrench is only worn at the jaws, resulting in a huge waste of materials. For this reason, the utility model provides a detachable stud bolt wrench. Utility Model Content

[0015] Beneficial effects

[0016] The utility model provides a disassembly type stud bolt wrench. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] (1) The detachable double-headed bolt wrench drives the screw to rotate by turning the hand wheel, and the first segment slides along the through groove through external operation. Since the movable link is rotatably connected to the first segment and the second segment respectively through the I-type coupling, the sliding of the first segment drives the movable link and the second segment to move accordingly, and finally the U-shaped plug rod is aligned and faces the positioning unit of the clamping part. When the U-shaped plug rod is driven by the moving unit to move to the vicinity of the positioning hole, the U-shaped plug rod is inserted into the positioning hole, thereby realizing the plug-in fixation of the handle and the clamping part. In specific applications, the two ends of the wrench can be quickly disassembled and assembled, and the clamping part can be replaced and updated when it is worn, thereby avoiding the problem of material waste caused by the wrench being unusable as a whole.

[0019] (2) The detachable stud bolt wrench has a groove on the clamping part, and two sets of clamping blocks arranged parallel to each other are slidably installed on the inner side. When the bolt needs to be clamped, the clamping blocks are pushed gradually closer and clamped by two sets of Z-shaped push rods symmetrically distributed with the center of the handle cross section as the axis point. The design of the ladder-shaped slider and the ladder-shaped slide groove ensures the stability and directionality of the sliding of the clamping blocks, so that the clamping distance of the stud bolts can be further adjusted when the wrench is assembled.
