[0002] In the leather production process, the vacuum dryer plays a role in preliminary drying of the leather, so that the leather is shaped and the surface is flat; usually when drying the leather, if the leather to be processed is to be laid on the bottom working panel, the upper working panel needs to be raised. In order to prevent the upper working panel from suddenly falling and injuring the operator laying the leather on the lower drying platform due to machine failure when it is raised, an extendable safety block is set on the inner side of the middle part of the top of the column. The extension and retraction of the safety block is manually driven by the operator;
