Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the Roman arc forming device for roof flashing includes a frame 1, which includes at least two symmetrically distributed L-shaped components. The two L-shaped components are fixedly connected by a connecting rod 11. The two ends of the frame 1 are respectively movably connected to a first adjusting frame 2 and a second adjusting frame 3. The first adjusting frame 2 and the second adjusting frame 3 slide along the length of the L-shaped components. The connecting rod 11 is hinged to a scraper 4 for forming a Roman arc in the direction of the inner angle of the L-shaped components.

[0020] The scraper 4 includes a scraper 41, a connector 42, a movable part 43, and a handle 44. One end of the connector 42 is rotatably connected to the connecting rod 11 via a hinge support 51, and the other end is movably connected to the movable part 43. The end of the sliding part 43 away from the connector 42 is fixedly connected to the scraper 41. The side of the scraper 41 away from the movable part 43 is provided with a handle 44 for driving the hanging part 4 to rotate around the connecting rod 11.

[0021] The keel frame 1 has pipe grooves 12 extending along its length at both ends. The first adjusting frame 2 and the second adjusting frame 3 are nested and slidably connected in the corresponding pipe grooves 12 on the keel frame 1. The keel frame 1, the first adjusting frame 2 and the second adjusting frame 3 are respectively provided with through holes distributed along their length. The through holes are positioned correspondingly. The first adjusting frame 2 is locked to the keel frame 1 by fasteners passing through the through holes, and the second adjusting frame 3 is locked to the keel frame 1 by fasteners passing through the through holes.

[0022] The connector 42 has a guide groove 45 along its length at one end connected to the movable part 43. The movable part 43 is slidably embedded in the guide groove 45 of the connector 42. The connector 42 and the movable part 43 are respectively provided with locking holes distributed along the length of the guide groove 45. The connector 42 and the movable part 43 are locked by inserting a locking pin into the locking hole.

[0023] When the scraper 4 rotates around the connecting rod 11 to 0°, the scraper 41 is in contact with the first adjusting frame 2. When the scraper 4 rotates around the connecting rod 11 to 90°, the scraper 41 is in contact with the second adjusting frame 3.

[0024] The first adjustment frame 2 has a support foot 21 at the end away from the keel frame 1, and the second adjustment frame 3 has a support foot 31 at the end away from the keel frame 1. The bottom of the support foot 21 and the support foot 31 are provided with anti-slip texture.

[0025] like Figure 3 As shown, the scraper 4 rotates around the connecting rod 11. The dashed line represents the trajectory range and adjustable range of the scraper 4.

[0026] like Figure 4As shown, the direction of the dotted line on the keel frame 1 is the sliding adjustment range of the first adjustment frame 2 and the second adjustment frame 3 in the corresponding pipe groove 12 on the keel frame 1, and the direction of the dotted line on the scraper 4 is the sliding adjustment range of the movable part 43 in the guide groove 45 of the connector 42.

[0027] In one embodiment of this utility model: the sliding length of the first adjusting frame 2 and the second adjusting frame 3 in the pipe groove 12 on the keel frame 1 is adjusted synchronously until a suitable construction position is reached. The keel frame 1 is locked to the first adjusting frame 2 and the second adjusting frame 3 by inserting fasteners into the through holes. The length of the first adjusting frame 2 connected to the keel frame 1 and the length of the second adjusting frame 3 connected to the keel frame 1 are the same. The movable part 43 slides in the guide groove 45 in the connector 42 until it reaches the construction surface. The connector 42 and the movable part 43 are locked by inserting a locking pin into the locking hole. The length of the scraper 4 is less than the length of the first adjusting frame 2 and the keel frame 1. The support foot 21 of the first adjusting frame 2 is vertically supported on the floor 5, and the support foot 32 of the second adjusting frame 3 is vertically supported on the wall 6. The handle 44 is held and driven to rotate the scraper 4 around the connecting rod 11. After repeated scraping, the scraper 41 scrapes the working surface into a Roman arc.
