After the lower section of the inner shaft in the actuating inner shaft 23 contacts the pressing piece 34 downwards, the pressing piece 34 is pressed to rotate downwards around the torsion spring fixing shaft. The right end of the pressing blade 34 first touches the inclined part of the snap spring 35, and the inclined part of the snap spring 35 provides an upward force to the pressing blade 34, so that the inner actuating shaft 23 remains stationary (moves upward relative to the outer actuating shaft 22, i.e., contracts) until the top surface of the inner actuating shaft 23 abuts against the top surface of the blind outer shaft hole. At this time, the inner actuating shaft starts moving downwards again, the pressing force is gradually increased, the right end portion of the pressing sheet 34 moves to the vertical portion along the inclined portion, the vertical portion basically does not generate elasticity on the pressing sheet 34, and the pressing force rapidly drops, so that the tactile feedback of the pressing process is realized. Meanwhile, the pressing piece 34 presses the microswitch 42 to realize circuit conversion. When the pressing force is released, the display part 1 is displaced upward to be reset due to the compressive restoring force of the torsion spring body 33 and the outer shaft spring 24.
