The invention relates to a wrench, in particular to a multifunctional telescopic hydraulic wrench which comprises a wrench fixing piece, a first handle piece and a second handle piece. The wrench fixing piece is formed by a secondary telescopic pipe, and a rotating ring body and a wrench fixing device symmetrically arranged at two ends of the secondary telescopic pipe; the first handle piece is formed by a middle plate, and an H-shaped ring body and a first handle symmetrically arranged at two ends of the middle plate; a hydraulic cylinder is rotatably arranged on one side, close to the firsthandle, on the middle plate; the second handle piece penetrates through the inner part of the H-shaped ring body and is matched with the H-shaped ring body; the wrench is arranged in the H-shaped ringbody; a wrench head is matched with the end part of a nut or a bolt, then the second handle piece is held by a left hand, the first handle is held by a right hand, and then an oil conveying pipe control device is controlled so as to control the hydraulic cylinder to stretch out and draw back; the wrench fixing piece and the first handle piece can mutually rotate, so that the nut or the bolt can be disassembled conveniently; and the secondary telescopic pipe can stretch out and draw back so as to be applicable to wrenches in different lengths.
Description
technical field [0001] The invention relates to a wrench, in particular to a multifunctional retractable hydraulic wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. Wrenches are usually made of structural steel of carbon or alloy materials. [0003] In some cases, when using a wrench, it is inconvenient for the user to use, and because the wrench as a whole is relatively short, it is inconvenient for the user to exert force. Traditional wrenches can no longer meet the requirements of users. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a multifunctional telescopic hydraulic wrench. [0005] In order to solve the above technical problems, the technical solution provided b...
