Similarly, loosening the screw can loosen the first fastening ring 412 and the second fastening ring 421 from the end close to the output shaft 231 and the end of the second coupling 42 close to the first coupling 41.

[0040] Furthermore, in one embodiment, a hollow connecting tube 413 sleeved with the output shaft 231 and a plurality of bayonet holes 414 in communication with the connecting tube 413 are provided at one end of the first coupling 41 close to the output shaft 231, and the bayonet holes 414 are used to enhance the elasticity of the first coupling 41 so as to facilitate the first fastening ring 412 to press the sleeve joint between the first coupling 41 and the output shaft 231.

Correspondingly, a key groove 4123 cooperating with the flat key 2311 is provided on the inner wall of the first fastening ring 412, so as to facilitate the first fastening ring 412 to be sleeved on one end of the first coupling 41 close to the output shaft 231.

[0041] Furthermore, in one embodiment, a rotating groove 422 cooperating with the rotating shaft 411 is formed at one end of the second coupling 42 close to the first coupling 41, and a fixing groove 4211 capable of being combined with the rotating groove 422 is formed on the inner wall of the second fastening ring 421, and the second fastening ring 421 presses the rotating shaft 411 into the combination of the rotating groove 422 and the fixing groove 4211.

The first half clutch 431 and the second half clutch 43 are arranged with a relative spacing and the opposite sides are provided with teeth 4301 that can mesh with each other. In this embodiment, when the second coupling 42 rotates under the drive of the driving motor 23, the first half clutch 431 and the second half clutch 43 are in a separated state, so that the second coupling 42 drives the first half clutch 431 to rotate together. When the second coupling 42 is touched by the rotating plate 22 and rotates, the first half clutch 431 and the second half clutch 43 are in a meshing state, so that the second half clutch 431 fixes the second coupling 42 through the first half clutch 43.

[0045] Furthermore, in one embodiment, the clutch 43 further includes an angle sensor 433, which is sleeved on one end of the second coupling 42 passing through the second mounting plate 106, that is, the angle sensor is located on the side of the second mounting plate 106 away from the second half clutch 432, and correspondingly, the second mounting plate 106 is provided with a second groove 1061 for the second coupling 42 to pass through. The angle sensor 433 is electrically connected to the second half clutch 43 and the driver 104, and controls the clutch state of the first half clutch 431 and the second half clutch 43 by detecting whether the second coupling 42 rotates normally. In this embodiment, the second coupling 42 rotates normally when it is driven by the driving motor 23, and the rotation in other cases is abnormal rotation, for example, the rotation of the second coupling 42 is caused by an illegal person forcibly pushing the rotating plate 22 on the door leaf 20.

[0046] The customs gate door 100 in the present invention is provided with a first fastening ring 412 and a second fastening ring 421 on the first coupling 41 and the second coupling 42, respectively, which are used to fix the first coupling 41 and the output shaft 231 and the second coupling 42 and the first coupling 41, respectively. The structure is simple and stable, which is beneficial to improving the coaxiality of the first coupling 41, the second coupling 42 and the output shaft 231, improving the rotation stability of the door leaf 20, and improving the service life.
