[0024] During use, the floor to be welded is placed on the welding table 1, and then the servo motor 6 is started. After the servo motor 6 is started, the screw rod 7 is driven to rotate. After the screw rod 7 rotates, it cooperates with the guiding effect of the guide rod 9 to drive the moving block 8 to reciprocate.

After the two-way cylinder 11 is started, the two adjusting plates 14 are driven to make relative reciprocating motions through the two output ends. After determining the size that matches the floor, the first handle 16 can be rotated. After the two first handles 16 are rotated, the two first threaded rods 15 are driven to rotate. After the first threaded rods 15 are rotated, the push plate 17 is pushed close to or away from the floor to be laid. When the push plate 17 is close to the floor, the second threaded rod 18 can be driven to rotate by the second handle 19. After the second threaded rod 18 is rotated, the second fixing plate 20 is driven to rise and fall in cooperation with the guiding effect of the adjusting groove, so that the bottom of the second fixing plate 20 contacts the ground, and then the push plate 17 is continued to be pushed so that the rear side of the second fixing plate 20 is pressed against the floor to fix the floor to be laid, which is convenient for the operator to perform secondary welding or fix it with screws on the laid floor.
