The invention relates to the technical field of hoisting equipment, in particular to a clutch of a lever hoist. The clutch comprises a brake base connected with a long shaft of the lever hoist. The long shaft penetrates through a front wall plate of the lever hoist. The brake base is disposed on the front side of the front wall plate and comprises a bottom disc and a mounting disc formed by extending from the bottom disc to the front side. A first friction plate, a ratchet wheel and a second friction plate are arranged on the periphery of the mounting disc in a sleeving mode in sequence in the direction from the bottom disc to the front side. A brake nut disposed on the front side of the second friction plate and provided with an abutting plane capable of abutting against the second friction plate is further arranged on the long shaft. Corresponding annular grooves are formed in side portions of the sides, which are opposite, of the mounting disc and the brake nut. Tips of the front end and the rear end of a clutch spring are arranged in the annular grooves respectively. The periphery of the brake nut is arranged on a lever unit of the lever hoist, and the front end portion of the brake nut is further connected with a hand wheel. The clutch of the lever hoist is simple and effective in structure, safe and stable in use, simple and flexible to operate, higher in carrying capacity and better in braking effect.
