spherical surface of the drive block, thereby forming a plurality of gaps. Thus, the gaps located between the drive block and the receiving hole keep a smooth circulation of the air flow, thereby preventing the drive block from being jammed in the receiving hole due to deformation of heat expansion, so that the control lever is operated normally.
