Abstract

The invention provides a telescopic cylinder piston rod thread fastening wrench. The telescopic cylinder piston rod thread fastening wrench comprises a handle, a holding hook and a fastening screw; the handle is provided with a first end and a second end in the length direction; the holding hook is shaped like an arc-shaped plate and provided with a first end and a second end in the circumferential direction, the first end of the holding hook is connected with the first end of the handle, and the curvature radius of the inner circumferential wall of the holding hook is matched with the radiusof a telescopic cylinder piston rod; and the fastening screw is used for circumferentially fixing the holding hook and the telescopic cylinder piston rod and arranged at the second end of the holdinghook in a threaded penetrating manner in the radial direction of the holding hook. According to the telescopic cylinder piston rod thread fastening wrench, the telescopic cylinder piston rod thread fastening wrench can stretch into a narrow space on the premise that a telescopic cylinder is not dismounted and taken out, and a threaded structure between the telescopic cylinder piston rod and corresponding other parts can be quickly fastened.

Description

technical field [0001] The invention relates to a wrench, in particular to a telescopic cylinder piston rod thread fastening wrench. Background technique [0002] After working for a period of time, the trimming and shearing oil cylinder at the entrance of the acid rolling of the automobile plate loosens the thread, resulting in the phenomenon that the trimming and shearing are not in place and the steel plate is continuously sheared. Due to the narrow space, it is impossible to use pipe wrench for fastening work, and there are no alternative tools available. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a threaded tightening wrench for the piston rod of the telescopic cylinder, which can be inserted into a narrow space and fastened without disassembling and taking out the telescopic cylinder. The thread structure between the telescopic cylinder pis...
