a circular sliding groove which is in circumferential sliding fit with the first clutch block and the second clutch block is arranged on the inner wall of the clutch gear, a first clutch groove which is smoothly guided and clamped with the first clutch block in an asymptote mode is formed in the circular sliding groove, a second clutch groove which is smoothly guided and clamped with the second clutch block in an asymptote mode is formed in the circular sliding groove, and the first clutch groove and the second clutch groove are symmetrically distributed by taking the central shaft of the clutch gear as the center;
when the clutch gear rotates forwards or reversely, at least one group of clutch blocks and clutch grooves are in a disengaged state in the first clutch block and the first clutch groove or the second clutch block and the second clutch groove;
when the clutch gear is in a forward rotation state, external force triggers the second clutch plate to drive the second clutch block to be in abutting fit with the second clutch groove, the first clutch block is separated from the first clutch groove, and the clutch gear is in abutting fit with the second clutch block through the second clutch groove to drive the damping inner rotating wheel and the operating shaft to rotate forward synchronously;
when the clutch gear is in a reverse state, external force triggers the first clutch plate to drive the first clutch block to be in abutting fit with the first clutch groove, the second clutch block is separated from the second clutch groove, and the clutch gear is in abutting fit with the first clutch block through the first clutch groove to drive the damping inner rotating wheel and the operating shaft to synchronously reverse;
when the clutch gear is in an idle running state, external force triggers the first clutch plate and the second clutch plate to drive the first clutch block and the second clutch block which respectively correspond to the first clutch plate and the second clutch plate to be separated from the first clutch groove and the second clutch groove which respectively correspond to the first clutch block and the second clutch plate, two groups of clutch blocks and clutch grooves are in a separated state, the clutch gear idles relative to the damping inner rotating wheel, and the damping inner rotating wheel and the operating shaft do not rotate;
the clutch gear and the driving force transmission gear are in gear engagement transmission and are fixedly sleeved on a first transmission gear on the operating shaft and are in transmission connection with a second transmission gear on the load switch shaft through a chain, and the operating shaft and the load switch shaft are fixed through a mounting frame.
5. The load switch operating mechanism of claim 4, wherein the clutch gear is coupled to the damped inner rotor via a bearing.
6. The load switch combination operating mechanism of claim 4, wherein the damped inner rotor is fixedly connected to the operating shaft by a latch.
7. The load switch combination operating mechanism according to claim 4, wherein an opening/closing brake control mechanism for contacting with the first clutch plate or the second clutch plate and controlling the interference engagement or disengagement of the first clutch block or the second clutch block with the corresponding first clutch groove or the second clutch groove is fixed on the mounting bracket.
8. The load switch combination operating mechanism of claim 4, wherein the operating shaft is secured to the mounting bracket by a bearing.
9. The load switch combination operating mechanism according to claim 4, wherein the driving force transmission gear is driven by a low-speed motor.
