Abstract

The invention relates to a wrench convenient to use in small space. The wrench convenient to use in small space comprises a shell, a meshing end is arranged at the front portion of the shell, and an operation end is arranged on the rear portion of the shell. A connecting section is arranged between the front portion and the rear portion of the shell, and the connecting section is made from a pipebarrel capable of being bent. A limiting groove is formed in the meshing end, and a meshing disc is detachably arranged in the limiting groove. Transmission teeth are arranged on the outer disc edge of the meshing disc, and a meshing groove is formed in the disc face of one side of the meshing disc. Transmission wheels are arranged in the connecting section in a meshing manner. The transmission wheel at the front end of the connecting section is closely engaged with the meshing disc. A driving wheel is arranged at the operation end, and the driving wheel and the transmission wheel at the rearend of the connecting section are locked through a pin ring and closely engaged. The wrench can be suitable for the small space, a screw can be effectively meshed and efficiently twisted in the narrowspace, and therefore the demounting and mounting efficiency of an instrument is improved, and then repairing and maintenance of the instrument are convenient.
