As a preferable example, one end of the swing arm close to the positioning shaft is provided with a plurality of positioning holes along the length direction, and one end of the tension spring is fixed in one of the positioning holes.

As a preferred example, the brake block is a cylindrical block.

As a preferable example, one surface of the inner fixed disc fixed with the connecting rod is provided with a groove, the connecting rod is provided with a bulge matched with the groove, and the limiting shaft extends out of the inner fixed disc and is connected with the connecting rod in a rotating way.

Through adopting above-mentioned technical scheme, the dismouting of being convenient for is maintained.

As a preferred example, there are two buffer drums.

The beneficial effects of the utility model are that under brake mechanism's effect, the reel is according to the paper supply needs rotation and stop between self-adaptation switch to avoided because the condition of rotation inertia leads to excessive paper supply, avoided appearing the problem of paper book, the production process is safe high-efficient more.
