The second plugging rod 61 is movably installed through the plugging sleeve 60, the second plugging rod 61 and the detection ball 62 at the end part are contacted with the surface to be detected under the cooperation of the spring column and the middle plate 71, the detection ball 62 passes through the detection surface at the top when the detection mechanism 6 swings under the driving of the swing driving mechanism 4, and the running path of the detection ball 62 is reduced in equal proportion and recorded on the recording sticker by cooperation with the recording mechanism 7. The center rod 65 and the detection mechanism 6 are slidably arranged between the semicircular frame 40, meanwhile, the center rod 65 is rotationally connected with the central shaft 10, and when the motor I43 drives the matched gear I44 to be meshed with the semicircular gear I42, the center rod 65 and the detection mechanism 6 are driven to rotate around the central shaft 10, so that the cambered surface detection record of the surface to be detected is realized. The L-shaped frame 72 moves along with the middle plate 71 and the second plugging rod 61, when the arc of the arc to be detected changes, the second plugging rod 61 slides relatively in the plugging sleeve 60, the L-shaped frame 72 and the recording pen 73 arranged at the end part move synchronously, and a changed track route is left on the recording sticker, so that the specific condition of the arc of the top can be judged according to the track route. The recording mechanism 7 is rotated ninety degrees by the indexing assembly so that the stylus 73 is rotated to the side of the mounting frame 1 while the recording plate 5 is transferred onto the mounting pins 55 of the central rod 65. The support column is moved and the winding motor 52 is started to pull the recording belt 53, and at the moment, the recording mechanism 7 records the surface condition of the top longitudinal detection surface on the recording belt 53, so that the longitudinal detection recording of the top cambered surface is realized. The recording groove 50 is formed in the recording plate 5, when the mark trigger rod 74 falls into the recording groove 50, the matching groove 764 on the mark trigger rod 74 is matched with the matching ball 763, at the moment, the matching ball 763 presses the electric control button under the drive of the tensioning spring II 762, so that the electric pump is started to drive the mark spray head 63 to spray paint outwards, a detection mark point is left on the top cambered surface, after the cambered surface is detected, an irregular cambered surface area can be quickly found by combining the position corresponding to the recording groove 50 on the recording sticker and the paint mark point on the cambered surface, and the cambered surface is trimmed conveniently. The movable frame 34 is combined with the contact balls 35 and the positioning frames 30 to be slidably mounted, meanwhile, the detection frames 36 are arranged, when the movable frame 34 slides on the detection frames 36, the resistance value of an access circuit in the resistance grooves 37 is changed, and the moving distance of the movable frames 34 at two ends of the mounting frame 1 is judged by detecting the resistance values on the positioning frames 30 at two sides, so that the mounting frame 1 is ensured to be positioned at the middle part. When the first inserting connection rod 20 and the locking pin 25 are separated from locking relation, the first inserting connection rod 20 is pushed upwards, the horizontal positioning mechanisms 3 on two sides of the mounting frame 1 are driven to be mutually folded by combining the linkage rod 23, and the whole space occupation of the device can be greatly reduced when the device is not used.
