The resistance wheel 601 and the resistance sheet 603 are kept in a compressed state in a normal state, so that a larger power is needed for driving the upper half shaft 508, when the follow-up sector gear 503 is meshed with the transmission gear 512, the follow-up sector gear 503 fixed at the output end of the motor 501 can overcome the compressed resistance to maintain the power transmission, and the lag quick-chasing sector gear 504 sleeved on the output end of the motor 501 by the positioning ring 505 lacks enough power source when the transmission gear 512 is meshed, so that the upper half shaft 508 and the lag gear ring 511 are in a pause state. After the trigger switch 604 contacts the trigger notch 605, the self-resetting electric push rod 602 contracts to release the locking state of the upper half shaft 508, so that the resetting power of the main torsion shaft 801 drives the lagging vertical rod 704 to accelerate into the U-shaped groove 703 of the synchronous vertical pipe 701 through the traction rope 805.
