[0002] At present, seats are basically divided into two kinds of leather seats and cloth seats. The automobile seat is mainly connected with the framework after being sewn with the cover, and the connecting part is generally a clamping strip. The clamping strip is fixed with the cover and then connected with the framework. When the seat clamping strip is produced, it needs to be cut into a shorter seat clamping strip according to the requirements on the cutting equipment. The seat clamping strip moves through the driving of the conveying roller on the cutting equipment. When the friction is not enough, it may cause the seat clamping strip to slip and be difficult to move. Therefore, the distance between the two rollers needs to be adjusted to ensure that the seat clamping strip can move smoothly. However, the distance between the two rollers in the prior art is not convenient to adjust, and the contact area with the clamping strip is limited only through the transmission of the two rollers, which is one of the causes of the slipping.
