Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0017] Such as Figure 1-2 As shown, a powerful wrench includes a long rod-shaped mounting frame 1. The mounting frame 1 is provided with a rotating base 3 that rotates around an axis perpendicular to the length of the mounting frame 1, and the rotating base 3 is provided with a rotating base perpendicular to the mounting frame 1. A threaded hole in the length direction. A screw rod 2 is inserted through the threaded hole. The end of the screw rod 2 is hinged with a pliers handle 4 through a driving pin. The pliers handle 4 is provided with a long hole arranged in the length direction to accommodate the driving pin. A worm wheel 5 is sleeved on the rotating seat 3, a worm 6 for driving the worm wheel 5 is rotated in the mounting frame 1, and a manual crank 7 is provided at the end of the worm 6. The end of the pliers handle 4 is provided with a jaw portion...

Description

Technical field [0001] The invention relates to a powerful wrench. Background technique [0002] The bolts on the pipes will rust to varying degrees after long-term use, and become very difficult to screw when they need to be disassembled. Therefore, the dismantling personnel often need to consume a lot of physical strength and time to deal with. [0003] Under normal circumstances, a longer tube needs to be fitted on the wrench to lengthen the moment arm to achieve disassembly. But this method requires a larger operating space. Once the disassembly work needs to be completed in a small space, it cannot be implemented. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a powerful wrench that can be used in a small space and is labor-saving. [0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a strong wrench, including a long rod-shaped mounting frame, the mounti...
