[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In order to facilitate the inspection of the propeller, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a base 1, a supporting frame 2, a rotating component, a limiting component and a positioning component. The supporting frame 2 is arranged on the base 1, and the rotating component includes a rotating frame 3 arranged in the supporting frame 2. The propeller is fixed in the rotating frame 3 through the limiting component. When the rotating frame 3 rotates to be at the same level as the supporting frame 2, the rotating frame 3 is fixed by the positioning component. The handle 8 is rotated according to the length of the propeller to be detected, and the threaded rod 6 is adapted to the threaded hole. After the handle 8 is rotated, the threaded rod 6 is driven to axially feed in the rotating frame 3. The size of the propeller limiting area between the upper clamping block 10 and the lower clamping block 7 is changed according to the length of the propeller. Subsequently, the two ends of the propeller are respectively inserted into the upper clamping block 10 and the lower clamping block 7 through the arc groove 11. After the front detection of the propeller is completed, the rotating frame 3 is driven to rotate by the rotation of the rotating shaft 5, so that the propeller rotates accordingly, so that the staff can perform all-round detection, saving time cost and improving work efficiency.

[0020] In order to facilitate the rotation of the propeller to be inspected, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating assembly also includes a fixed block 4 centrally arranged on both sides of the support frame 2, and a rotating shaft 5 is inserted on the adjacent sides of the two fixed blocks 4. Through holes are provided on both sides of the rotating frame 3, and the rotating shaft 5 is inserted into the through holes. The rotating shaft 5 is supported by the fixed block 4, and then the rotating frame 3 is supported, thereby improving the stability of the rotating frame 3 during rotation. The limiting assembly includes a threaded hole provided at the lower part of the rotating frame 3, and a threaded rod 6 is inserted into the threaded hole. The thread on the inner wall of the threaded hole is adapted to the outer thread on the outer wall of the threaded rod 6. As the handle 8 is rotated, the threaded hole can be driven to axially feed toward the rotating frame 3. The threaded rod 6 is provided with a lower clamping block 7 at one end in the rotating frame 3, a handle 8 is provided at one end of the threaded rod 6 away from the clamping block, a fixing rod 9 is provided at one end in the rotating frame 3 away from the threaded rod 6, and an upper clamping block 10 is connected to the end of the fixing rod 9. The lower clamping block 7 is driven to move by the axial feeding of the threaded rod 6, and the distance between the upper clamping block 10 and the lower clamping block 7 can be adjusted by the length of the propeller to improve flexibility. The upper clamping block 10 and the lower clamping block 7 are both provided with an arc groove 11 adapted to the outer arc of the propeller on the side facing the propeller, and the arc groove 11 is adapted to the outer arc edge of the propeller, thereby fixing the propeller. The positioning assembly includes a socket opened on the upper surface of the supporting frame 2, a positioning rod 12 that can move up and down is arranged in the socket, and a round hole that is compatible with the positioning rod 12 is opened on the upper part of the rotating frame 3. When the rotating frame 3 is rotated to a state parallel to the supporting frame 2, the positioning rod 12 is used to pass through the socket and the round hole in sequence, so that the rotating frame 3 can be fixed.

[0021] When in use, the handle 8 is rotated according to the length of the propeller to be tested, and the threaded rod 6 is adapted to the threaded hole. After the handle 8 is rotated, the threaded rod 6 is driven to axially feed in the rotating frame 3, and the size of the propeller limiting area between the upper clamping block 10 and the lower clamping block 7 is changed according to the length of the propeller. Then, the two ends of the propeller are respectively inserted into the upper clamping block 10 and the lower clamping block 7 through the arc groove 11. When the front side of the propeller is inspected, the rotating frame 3 is driven to rotate by the rotation of the rotating shaft 5, so that the propeller rotates accordingly.
