First, the micro servo motor 86 is started, driving the second bevel gear 87 to rotate via its output shaft. The cooperation between the second bevel gear 87 and the first bevel gear 83 causes the threaded shaft 82 to rotate, driving the two threaded plates 84 to move relative to each other. At this point, the two threaded plates 84 drive the two limit shafts 85 to move relative to each other until both limit shafts 85 are inside the connecting frame 81. Then, the support table 7 is pulled upwards to remove it, thus facilitating the disassembly and replacement of the support table. The purpose of disassembly and replacement is to improve the practicality of the mechanism. By setting the positioning component 9, the workpiece is placed on the support platform 7. Then, the rotating screws 92 on the left and right sides are rotated to drive the two clamping blocks 93 to move relative to each other until the two clamping blocks 93 are in contact with the surface of the workpiece, thereby achieving the purpose of positioning the workpiece. This further improves the practicality of the mechanism and solves some defects that still exist in the use of the current traditional workpiece transmission mechanism. For example, the support platform is mostly fixed by welding, which is inconvenient when disassembly and replacement are required. Secondly, the workpiece cannot be positioned when placed above the transmission mechanism and is prone to displacement.
