TUBULAR MEMBER AND HOLDING MOUNT ASSEMBLY

原文（中国語）

A tubular member and holding mount assembly includes a holding mount having an axial hole, a tubular member inserted into the axial hole in a manner that allows axial movement and rotation relative to the holding mount, an eccentric handlebar swingably mounted to the holding mount to restrict or permit the axial movement of the tubular member depending on its position, and a limiting member rotatably mounted to the holding mount for selectively restricting both the rotation of the tubular member and the swinging movement of the eccentric handlebar. When properly coordinated, the limiting member prevents the tubular member from rotating and the eccentric handlebar from being unintentionally released, thereby enhancing the stability and operational safety of the assembly.
