Electrodeless sleeve

The invention relates to the technical field of sleeves, in particular to an electrodeless sleeve. The electrodeless sleeve comprises a rotating rod, a sleeve body, a mounting head, a sliding cavity,a threaded rod, a rotating ring, a limiting shell, a first bevel gear, clamping blocks, a second bevel gear, a connecting rod, a limiting plate, a third bevel gear, a fourth bevel gear and a rotatingcylinder. The electrodeless sleeve is simple in structure and novel in design, a worker can conveniently adjust the positions of the three clamping blocks in the sleeve according to the sizes of nutsof different models, the disassembled and assembled nuts can be stably clamped conveniently, the worker can operate the sleeve to rotate conveniently, the nuts can be disassembled conveniently, and operation is convenient; and under the action of an arranged rotating mechanism, workers can conveniently and indirectly adjust the clamping blocks, the positions of the clamping blocks in a sleeve bodycan be conveniently adjuste
