The sliding block 103 is mounted on the side of the support plate 102 via the telescopic member, allowing the sliding block 103 to support the support plate 102. The sliding rail 104 is fixedly mounted on the inner side of the housing 100 and has a groove that mates with the sliding block 103, allowing the sliding block 103 to move within the sliding rail 104. The fixing rod 105 passes through the sliding rail 104 and the sliding block 103, thereby fixing the sliding block 103 at a specified angle on the sliding rail 104. This allows the sliding block 103 to support the support plate 102, positioning the support plate 102 at a specified height. This enables more convenient adjustment of the fan height, improves adjustment efficiency, and enhances the practicality of the equipment.

[0022] Secondly, the fixing plate 106 is detachably connected to the support plate 102 and is located on the side of the support plate 102 away from the housing 100; the mounting block 107 is fixedly connected to the fixing plate 106 and is located on the side of the fixing plate 106 away from the support plate 102.
