The other end of the limit bolt five (33) passes through the scale line one (1106) and is threadedly connected to the inside of the threaded groove one (27).

8. The wing shape detection fixture according to claim 1, characterized in that: The two measuring rods 1 (12) are both threadedly connected to the limit bolt 2 (19) on the side walls close to the indicating block (18), and the side walls of the measuring rods 1 (12) are each provided with a threaded groove 3 (36) for the limit bolt 2 (19) to be threadedly connected, and the side walls of the measuring rods 1 (12) are each provided with a groove 2 (20), and the middle of the measuring rods 2 (13) is provided with a slide groove 1 (37), and the internal dimensions of the slide groove 1 (37) are respectively matched with the external dimensions of the measuring rods 1 (12), and the side walls of the measuring rods 2 (13) away from the contact (14) are threadedly connected to the limit bolt 3 (21), and the limit bolt 3 (21) passes through the measuring rods 2 (13) and is inserted into the inner bottom of the groove 2 (20).

9. A wing shape detection fixture, using the wing shape detection fixture as described in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Height adjustment, the base (1) is placed on the ground near the tail of the wing, the operator slides the support column 2 (3), changes the height of the support column 2 (3) inserted into the inside of the slide groove 2 (38), so that the mounting seat 4 (1101) is flush with the tail of the wing, and then rotates the limit bolt 1 (17) to support the anti-sliding block (39) on the inner wall of the groove 1 (15), thereby limiting the sliding of the support column 2 (3) through friction resistance. S2: Angle adjustment. By observing whether the bubble of the level bubble (25) is centered, the operator turns the connecting tube (601) at the corresponding position in turn, thereby changing the height of the mounting seat 2 (7) and the support of the turntable (8), so that the bubble of the level bubble (25) is centered, thereby ensuring that the turntable (8) is level. The operator turns the turntable (8) and observes the direction indicated by the indicator needle 2 (24) to confirm the angle reading. The operator then turns the limit bolt 4 (32) counterclockwise to fix the turntable (8), then turns the mounting seat 4 (1101) and observes the direction indicated by the pointer 1 (1107) to confirm the bending direction of the crossbar (1102), and then turns the limit bolt 5 (33) counterclockwise to fix the mounting seat 4 (1101). S3: Wing measurement, the operator makes the two measuring rods 2 (13) extend to the same length, slides the measuring rod 1 (12) so that the contact point (14) overlaps the top and bottom ends of the wing in turn, tightens the limit bolt 2 (19) to allow the measuring rod 1 (12) to slide, and then observes the scale line 1 (1106) indicated by the two sets of indicator blocks (18), thereby obtaining the wing thickness data, then loosens the limit bolt 2 (19) to slide the measuring rod 1 (12), and then loosens the limit bolt 3 (21) to slide the measuring rod 2 (13), thereby extending the distance between the contact point (14) and the ruler (1103), and measuring the wing thickness on the same horizontal plane.
