[0034] The working principle is that when a metal roof installation device is used, in the initial state, first, the first roof panel 2 and the second roof panel 203 are connected by clamping connection of the first locking strip 201 and the second locking strip 202, the locking machine main seat 1 and the locking machine auxiliary seat 102 are rotatably connected with the first locking wheel 104 and the second locking wheel 105 at the bottom of the first roof panel 2 and the second roof panel 203, and the locking machine main seat 1 is provided with a driving motor 101 at the top, so as to facilitate the locking treatment of the first locking strip 201 and the second locking strip 202, and the side frame 301 provided on one side of the locking machine main seat 1 is connected with the rotating seat 303 through the rotating rod 302, the bottom end of the supporting arm 313 fixedly connected on the rotating seat 303 is provided with the anti-skid block 314, the locking rod 307 connected on the rotating seat 303 is clamped with the side plate 311 on the side frame 301, so as to facilitate supporting the locking machine main seat 1 and preventing sliding by the anti-skid block 314, and the lifting block 403 controlled by the second spring 405, the threaded rod 408 and the clamping block 409 is slidably connected in the side frame 301 provided on both sides of the locking machine main seat 1, and the bottom of the lifting block 403 is further provided with the bottom groove 411, the movable block 412 and the pulley 413, so as to facilitate the pulley 413 to quickly support the locking machine main seat 1.

[0035] When it is needed to quickly support the locking machine main seat 1, first, after the locking machine main seat 1 and the locking machine auxiliary seat 102 are fixed on the first locking strip 201 and the second locking strip 202 by the second locking wheel 105 and the first locking wheel 104, the adjusting rod 410 is reversely rotated to drive the threaded rod 408 to rotate, the rotating threaded rod 408 moves outward under the action of the threaded groove 406 to pull the movable groove 407 to move outward to be separated from the contact with the inner wall of the supporting frame 401, so as to release the clamping locking of the lifting block 403, at this time, the second spring 405 is compressed to quickly rebound to push the lifting block 403 to move downward, and the lifting block 403 moves downward to drive the movable block 412 and the pulley 413 to move downward until the pulley 413 is in contact with the upper surface of the first roof panel 2 and the second roof panel 203, at this time, the adjusting rod 410 and the threaded rod 408 are forwardly twisted to push the clamping block 409 to move inward to clamp and lock the lifting block 403, after the lifting block 403 is locked, the driving motor 101 is started to perform the locking treatment of the first locking strip 201 and the second locking strip 202 by the second locking wheel 105 and the first locking wheel 104 under the support of the supporting mechanism 4 on the locking machine main seat 1 and the locking machine auxiliary seat 102, if the surface flatness of the first roof panel 2 and the second roof panel 203 is poor, when the surface is convex, the movable block 412 is lifted in the inside of the bottom groove 411, when the surface is concave, the third spring 414 pushes the movable block 412 to move downward, so that the pulley 413 is always closely attached to the surface of the first roof panel 2 and the second roof panel 203 to provide support, which facilitates the quick support of the locking machine main seat 1.

[0036] When it is needed to prevent the main seat 1 of the seaming machine from sliding off the first roof panel 2 or the second roof panel 203, first, hold the pull handle 304 and pull it down to rotate the rotating seat 303 downward by means of the rotating rod 302, the rotating rotating seat 303 pushes the support arm 313 and the anti-skid block 314 to move downward until the anti-skid block 314 slightly lifts one end of the main seat 1 of the seaming machine and the anti-skid block 314 contacts the surface of the first roof panel 2 or the second roof panel 203, when the rotating seat 303, the support arm 313 and the anti-skid block 314 rotate and move downward, the lock rod 307 on both sides of the rotating seat 303 also moves downward, since the outer end of the lock rod 307 is provided with the sliding head 309, the sliding head 309 will contact the limiting hole 312 and push the lock rod 307 inward to switch different hole positions during the downward movement of the lock rod 307, after the support arm 313 supports the main seat 1 of the seaming machine and the anti-skid block 314 contacts the first roof panel 2 or the second roof panel 203, the first spring 306 pushes the lock rod 307 to move outward and insert into the corresponding limiting hole 312 to lock the rotating seat 303, thus the device prevents the main seat 1 of the seaming machine from sliding off the first roof panel 2 or the second roof panel 203.
