When the second gear 44 is meshed with the second bevel gear 46 in the present invention, the movement of the drive ring 36 is synthesized by the movement of the three fifth gears 57 rotating about their own axes and the movement of the three fifth gears 57 rotating about the first rotary shaft 39; the four sixth springs 54 in the stretched state provide a restoring force to the third rotating shaft 63. The inclination of the contact surface of the first limiting notch 67 and the limiting block 26 is smaller; so that the stop block 26 and the release block 28 are not easily disengaged; the inclination of the contact surface of the reset inclined surface 68 and the limiting block 26 is larger; allowing the stop block 26 to be easily disengaged from the release block 28.

As shown in fig. 18 b, the fourth spring 32 transmits a counter acceleration force to the hammer core 3 after the release of the block increases the pressure; subjecting the core 3 to a downward pressure; at the moment, the reverse acceleration force of the fourth spring 32 to the hammer core 3 is basically the same as the acting force of the release block 28 to the hammer core 3 when the release block 28 is not separated from the limit block 26, so that the acceleration force can be obtained in the release process of the release block, and the pressure is continuously applied to the ground; the time of the acting force of the hammer core 3 on the floor is prolonged by the accelerating force; after the floor is corrected, the electronic valve 62 is controlled to enable the space between the telescopic cylinder sleeve 31 and the sleeve air inlet pipe to be in a closed state; at the moment, the worker lifts the floor hammer; the gas in the telescopic sleeve 31 flows into the atmosphere through a sleeve gas inlet pipe; the release block 28 is gradually restored to the original position under the action of the third spring 25; the hammer core 3 is gradually restored to the original position under the action of the second spring 22; the stopper 26 is returned to its original position by the fifth spring 34.
