As one specific embodiment, the door coupling end 222 is provided with a fastening projection 2221. The door coupling end 222 can be prevented from rotating with respect to the shaft coupling part 111, so that the effect of clamping and fixing the door coupling end 222 can be improved.

As one specific embodiment, the cross-section of the fastening projection 2221 is triangular, and the tip of the triangle is located approximately at the side of the door coupling end 222, thereby forming the fastening projection 2221. When the side wall of the clamping cavity 131 abuts against the door connecting end 222, the top end of the triangle of the cross section of the fastening projection 2221 is slightly deformed, so that the fastening projection 2221 goes beyond the side wall of the clamping cavity 131 and/or the side wall of the shaft connecting groove 118, so that the fastening projection 2221 abuts against the bottom end face of the movable mounting member 13 and/or the bottom end face of the shaft connecting portion 111, thereby making it possible to ensure that there is no slippage between the door connecting end 222 and the shaft connecting portion 111 in the height direction.

In a specific embodiment, a tip clearance 134 is provided between the tip of the shaft connecting portion 111 and the highest one of the tip of the movable attachment 13 and the tip of the door connecting end 222. The movable attachment 13 or the door connection end 222 can be prevented from protruding to damage the door body 93. When the door 93 is made of glass, it is particularly necessary to pay attention to damage by the roof.
