Furthermore, a lock nut is arranged outside the rack on the screw rod through threads, and the screw rod is locked through the lock nut.

Further, the driving mechanism is a hand lever or a motor.

The utility model has the beneficial effects that:

1. in the process of clamping and conveying the lath between the upper row of rollers and the lower row of rollers, under the extrusion action of the outer circular surface of one row of rollers and the annular groove of the other row of rollers, the two sides of the lath are continuously bent to form a U shape, the structure is simple, the operation is convenient, the forming shape of a product is smooth, and the air sealing effect is good.

2. The position of the guide wheel is adjusted up and down through the position adjusting mechanism, the bending curvature of the U-shaped plate strip is adjusted, and then U-shaped air seal rings with different diameters are processed, so that the U-shaped air seal ring is suitable for products with different diameters, and the manufacturing cost is low.
