In order to provide a holding force when the door hovers, further, the lead screw nut 511 is fixedly connected with the elastic block and contacts the guide housing 330, so that the elastic block forms a friction pair with the guide housing 330 and provides a friction damping force to the elastic block. That is, the holding force after the door is opened by a certain angle is provided by the increased friction force of the elastic block to the screw nut 511, the response time is not required, and the elastic restoring force of the elastic block can be adjusted by the material, the size and the like of the elastic block, so that the adaptation customization can be performed according to different holding force demands of customers.
