[0034] Working principle: when a metal roof installation device is used, in the initial state, the first roof panel 2 and the second roof panel 203 are firstly connected by using the first locking strip 201 and the second locking strip 202, and the bottom of the locking machine main seat 1 and the locking machine auxiliary seat 102 arranged on the first roof panel 2 and the second roof panel 203 are rotatably connected with the first locking wheel 104 and the second locking wheel 105, and the top of the locking machine main seat 1 is provided with a driving motor 101, so as to facilitate the locking of the first locking strip 201 and the second locking strip 202, and the side frame 301 arranged on one side of the locking machine main seat 1 is connected with the rotating seat through the rotating rod 302. 303 is connected, and an anti-sliding block 314 is installed at the bottom end of the supporting arm 313 fixedly connected to the rotating seat 303. At the same time, the locking rod 307 connected to the rotating seat 303 is clamped with the side plate 311 on the side frame 301, so as to support the main seat 1 of the overlocking machine and prevent it from sliding by the anti-sliding block 314. At the same time, the lifting blocks 403 controlled by the second spring 405, the threaded rod 408 and the clamping block 409 are slidably connected in the side frames 301 arranged on both sides of the main seat 1 of the overlocking machine, and the bottom groove 411, the movable block 412 and the pulley 413 are also arranged at the bottom of the lifting block 403, so that the pulley 413 can quickly support the main seat 1 of the overlocking machine;

[0035] When it is necessary to quickly provide support for the main seat 1 of the overlocking machine, first, after the main seat 1 of the overlocking machine and the auxiliary seat 102 of the overlocking machine are fixed on the first overlocking strip 201 and the second overlocking strip 202 by using the second overlocking wheel 105 and the first overlocking wheel 104, the gripping adjustment rod 410 is rotated in the opposite direction to drive the threaded rod 408 to rotate accordingly. The rotating threaded rod 408 moves outward under the action of the threaded groove 406, and the pulling movable groove 407 moves outward to break away from the contact with the inner wall of the support frame 401, thereby releasing the clamping lock of the lifting block 403. At this time, the compressed second spring 405 rebounds quickly to push the lifting block 403 downward, and the downward lifting block 403 drives the movable block 412 and the pulley 413 to move downward until the pulley 413 contacts the upper surface of the first roof panel 2 and the second roof panel 203. At this time, the adjustment can be turned forward. The rod 410 and the threaded rod 408 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 can be started. Under the support of the main seat 1 of the locking machine and the auxiliary seat 102 of the locking machine by the supporting mechanism 4, the first locking wheel 105 and the first locking wheel 104 can be used to lock the first locking strip 201 and the second locking strip 202. If the surface flatness of the first roof panel 2 and the second roof panel 203 is poor, the movable block 412 will rise inside the bottom groove 411 when the surface is convex, and the third spring 414 will push the movable block 412 to move downward when the surface is concave, so that the pulley 413 will always be in close contact with the surface of the first roof panel 2 and the second roof panel 203 to provide support. This device is convenient for quickly providing support to the main seat 1 of the locking machine.

[0036] When it is necessary to prevent the main seat 1 of the edge locking machine from sliding off the first roof panel 2 or the second roof panel 203, first, when the main seat 1 of the edge locking machine is on standby, hold the pull handle 304 to pull the rotating seat 303 downward to make it rotate downward using the rotating rod 302, and the rotating rotating seat 303 pushes the supporting arm 313 and the anti-sliding block 314 to move downward until the anti-sliding block 314 slightly lifts one end of the main seat 1 of the edge locking machine and the anti-sliding block 314 contacts the surface of the first roof panel 2 and the second roof panel 203. When the rotating seat 303, the supporting arm 313 and the anti-sliding block 314 rotate downward, the locking rods 303 on both sides of the rotating seat 303 7 also moves downward. Since a slider 309 is provided at the outer end of the locking rod 307, the slider 309 will contact the limiting hole 312 during the downward movement of the locking rod 307 and push the locking rod 307 inward to achieve switching of different hole positions. After the support arm 313 completes the support of the edge locking machine main seat 1 and the anti-sliding block 314 contacts the first roof panel 2 or the second roof panel 203, the first spring 306 will push the locking rod 307 to move outward and insert it into the corresponding limiting hole 312 to lock the rotating seat 303. This device is convenient for preventing the edge locking machine main seat 1 from sliding off the first roof panel 2 or the second roof panel 203.
