Abstract
A torque sleeve wrench comprises an outer cylinder, a first shaft sleeve and a rotary shaft, wherein the first shaft sleeve is fixedly sleeved inside the outer cylinder, and the rotary shaft is pivoted with the first shaft sleeve. An elastic part is sleeved on the rotary shaft; a torque adjusting device capable of compressing the elastic part is arranged at one end of the rotary shaft; and the torque adjusting device consists of a first end cover, a second end cover and a drive part, wherein the first end cover is connected with the rotary shaft through threads, the second end cover matching with the first end cover is capable of axially sliding along the rotary shaft, the drive part is arranged between the first end cover and the second cover, and the second end cover arranged below the first end cover is positioned above the elastic part. When the drive part drives the first end cover to rotate downwards, the first end cover downwards presses the second end cover, the second end cover tight compresses the elastic part, and the torque of the torque sleeve wrench is increased. When the drive part drives the first end cover to rotate upwards, the second end cover slides upwards under the action of the elastic force of the elastic part, and the torque of the torque sleeve wrench is decreased. The torque sleeve wrench has stable torque and small fluctuation when in torque adjustment, and is convenient in operation as the outer cylinder needs no disassembly.
