Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, a special tool for detaching a bearing of a pulley block assembly of a cigarette making machine comprises a hollow tension rod 1, a connection part 2 and a drawing structure 3, and is characterized in that the hollow tension rod 1 comprises a first barrel 11 and a clamping rod 12, the clamping rod 12 is integrally formed with the first barrel 11, one end of the clamping rod 12, which is far away from the first barrel 11, is provided with a clamping edge 13, the clamping rod 12 is uniformly provided with a plurality of notches 14 along a radial direction, the first barrel 11 is further provided with a threaded through hole 16, the connection part 2 comprises a second barrel 21, the second barrel 21 is provided with a threaded hole 22, the second barrel 21 is provided with a mandril 23, which is far away from the threaded hole 22, the mandril 23 is fixedly connected with the outer surface of one end of the mandril 23, which is near the second barrel 21, is provided with an external thread matched with the threaded through hole 16, and the other end of the mandril 23 can be extended into the clamping rod 12, the drawing structure 3 comprises a connecting rod 31 and a drawing sleeve 32, wherein an external thread matched with the threaded hole 22 is arranged at one end, far away from the drawing sleeve 32, of the connecting rod 31.
