Abstract:
Provided are a roller brush clamping device and a roller brush, which relate to the technical field of clamping tools. The roller brush clamping device comprises a support, a first clamping assembly and a second clamping assembly, wherein the support comprises a base cylinder with two ends being in communication with each other; the first clamping assembly comprises a driving adjustment cylinder connected in the base cylinder in a threaded manner, and a first clamping arm fixedly connected to the driving adjustment cylinder; and the second clamping assembly comprises a driven adjustment arm that is slidably snap-fitted to the base cylinder and is connected in the driving adjustment cylinder in a threaded manner, and a second clamping arm fixedly connected to the driven adjustment arm. Threads on the base cylinder, the driving adjustment cylinder and the driven adjustment arm are screwed in the same direction, and the pitch of the threads on the driven adjustment arm is twice the pitch of the threads on the base cylinder. The roller brush comprises a brush head and the roller brush clamping device, wherein the brush head is pivoted between the first clamping arm and the second clamping arm of the roller brush clamping device. When the roller brush clamping device is used, the mounting and dismounting convenience of the brush head is high, and the brush head can be kept centered during clamping.
