The fixing seat 9 is U-shaped. The upwarp pressure welding mechanism comprises a mounting seat 11, a first pressure welding head 3, a second pressure welding head 4, a profiling 7 and a driving piece. The inner side (i.e., the top) of the first bonding tool 3 is fixed to the holder 9 by an intermediate block 12. The driving member employs a cylinder 8. The cylinder 8 is fixed on the fixing seat 9, and the piston rod faces the first pressure welding head 3. The piston rod of the cylinder 8 is fixed with the mounting seat 11. The second bonding tool 4 is fixed to the mount 11. The second bonding tool 4 is arranged opposite to the outer side surface of the first bonding tool 3.

The convex block at the bottom of the profiling 7 and the sliding groove on the mounting seat 11 form a sliding pair. The profiling 7 is provided with a waist-shaped stepped hole. Fastening bolts are arranged in the waist-shaped stepped holes. The screw rod of the fastening bolt and the threaded hole on the chute form a screw pair.
