Preferably, both sides of the first limiting part 241 facing the second rotating shaft 112 and one side of the second limiting part 242 facing the second rotating shaft 112 are arc-shaped protruding structures facing the second rotating shaft 112, so that the precision of the limiting positions of the first limiting part 241 and the second limiting part 242 on the second rotating shaft 112 is improved by adapting to the small size of the end part of the second rotating shaft 112 and being easier to control through the height of protruding points.
According to some specific embodiments of the present application, referring to fig. 1, 2, 3, 4, 5, 6, 7, 8, and 9, the second stopper 242 is formed with a third groove 245 opened along its length direction and both ends thereof, which includes a third notch 246; the third notch 246 faces in a direction in which it approaches the first stopper 241.
One end of the first limiting piece 241 is positioned in one end of the third groove 245 and is rotatably connected with the second limiting piece 242; when the other end of the screw rod is connected with the other end of the second limiting piece 242, one end of the first limiting piece 241 is located in the third groove 245.
The quick connecting device of the embodiment positions the second limiting piece 242 in the direction perpendicular to the plane of the first limiting piece 241 through the connection between the third groove 245 of the second limiting piece 242 and the first limiting piece 241, prevents the connection between the second limiting piece 242 and the second rotating shaft 112 from being separated, and improves the limiting stability.
Preferably, the second limiting member 242 is a rib plate assembly; the third groove 245 includes a first groove wall 247, a groove bottom 248, and a second groove wall 249, which are respectively formed by separate rib plates. The second elongated through hole 244 may be provided on the groove bottom 248 or on a rib plate parallel to the groove bottom 248 and fixedly connected to the first groove wall 247 and the second groove wall 249.
