The upper end of the flywheel is arranged on the driven shaft; when the driven shaft rotates, the flywheel can be driven to rotate; the rotating speed of the flywheel can be effectively accelerated through the speed change mechanism, and the running at a heightened speed can be maintained; when the release block moves upwards and the arc-shaped groove on the release block is contacted with the bulge, the flywheel drives the bulge arranged on the lower side of the release block to rotate; the protrusion moves to impact the wall of the arc-shaped groove, and a downward pressure is applied to the release block in the process to enable the release block to move downwards; at the moment, the flywheel is also subjected to resistance of the release block to slow down the rotating speed of the flywheel; when the release block is completely separated from the flywheel, the rotating speed of the flywheel is increased again under the action of the driving motor and the speed change mechanism; to prepare for the next corrective action.

In the invention, a third rotating shaft is nested in a driving shaft; the annular sleeve is arranged on the driving shaft, and four sixth springs are arranged between the annular sleeve and the third rotating shaft; the first gear and the second bevel gear are arranged on the third rotating shaft; the second gear is arranged on the second rotating shaft; one end of the second rotating shaft is provided with a first bevel gear; the second gear is meshed with the second bevel gear; the third gear is arranged at one end of the first rotating shaft and is meshed with the first gear; the third bevel gear is arranged on the first rotating shaft through a bearing and is meshed with the first bevel gear; the supporting ring is arranged at one end of the third bevel gear; the three connecting rods are arranged at one end of the supporting ring; the three fifth gears are respectively arranged on the three connecting rods; the fourth gear is arranged at the other end of the first rotating shaft; the fourth gear is meshed with three fifth gears, and the three fifth gears are meshed with internal teeth on the driving ring; the driven shaft is arranged on the driving ring; when the driving shaft rotates, the circular ring sleeve is driven to rotate, the circular ring sleeve drives the third rotating shaft to rotate under the action of the sixth spring, and the rotating speed of the third rotating shaft is lower than that of the driving shaft; the driving shaft is connected with the third rotating shaft through threads; the rotation of the driving shaft can cause the third rotating shaft to move, and the rotation of the third rotating shaft drives the second bevel gear and the first gear to rotate; the third bevel gear rotates to drive the second gear to rotate; the second gear wheel rotates to drive the second rotating shaft to rotate; the second rotating shaft rotates to drive the first bevel gear to rotate; the first bevel gear drives the third bevel gear to rotate; the third bevel gear rotates to drive the supporting ring to rotate; the support ring rotates to drive the three connecting rods to rotate around the axis of the first rotating shaft; the three connecting rods rotate to drive the three fifth gears to rotate around the axis of the first rotating shaft; the three fifth gears rotate to drive the driving ring to rotate; meanwhile, the rotation of the first gear can drive the third gear to rotate; the third gear rotates to drive the first rotating shaft to rotate; the first rotating shaft rotates to drive the fourth gear to rotate; the fourth gear rotates to drive the three fifth gears to rotate; the three fifth gears rotate to drive the driving ring to rotate; the driving ring rotates to drive the driven shaft to rotate. According to the invention, the third rotating shaft moves while rotating, the third rotating shaft drives the second bevel gear to move during movement, and the rotating speed of the second gear meshed with the second rotating shaft is continuously changed while the second bevel gear in movement rotates because the outer diameter of the second bevel gear is continuously changed; the speed change mechanism designed by the invention has the function of adjusting the torque of the driven shaft, and can drive the flywheel to work through a motor with lower power; the overall weight of the floor hammer is reduced.

When the second gear is meshed with the second bevel gear, the motion of the driving ring is synthesized by the motion of the three fifth gears rotating around the axes of the fifth gears and the motion of the three fifth gears rotating around the first rotating shaft; by changing the speed of either movement, the speed of movement of the drive ring will change. The four sixth springs in the stretched state provide a restoring force to the third shaft. The inclination of the contact surface of the first limiting notch and the limiting block is smaller; so that the limiting block and the releasing block are not easy to separate; the inclination of the contact surface of the reset inclined plane and the limiting block is larger; so that the limiting block is easy to separate from the releasing block. The third limiting ring has a limiting effect on the first gear; the first limiting ring has a limiting effect on the third gear; the fourth fixing ring has a limiting effect on the fourth gear; the fifth fixing ring plays a limiting role in the fifth gear.

In the use process of the floor hammer, the four sixth springs are in a free telescopic state; the first spring, the second spring, the third spring, the fourth spring and the fifth spring are in a free telescopic state; the meshing point of the second gear and the second bevel gear is at the maximum of the diameter of the second bevel gear; when workers need to correct the floor, the floor is beaten by the floor hammer, and the hammer core can move upwards under the action of a reaction force of the floor; the hammer center moves upwards to drive the fourth spring to compress upwards; the second spring is compressed upwards; the fourth spring can push the release block to move upwards; at the moment, the third spring is gradually pulled open; the limiting block moves into the limiting groove; the fifth spring is compressed; when the resistance of the limiting block to the releasing block is smaller than the thrust of the fourth spring to the releasing block, the fourth spring pushes the releasing block away to enable the releasing block to be separated from the constraint of the limiting block; when the arc-shaped groove on the release block is contacted with the protrusion in the upward moving process of the release block, the flywheel drives the protrusion arranged on the lower side of the release block to rotate to separate from the arc-shaped groove; when the bulge is separated from the arc-shaped groove, downward pressure is applied to the release block to enable the release block to move downwards, so that the impact force of the hammer core on the release block is counteracted, and the noise is reduced; meanwhile, the releasing block moves downwards and applies downward pressure to the hammer core through a fourth spring; at the moment, the reverse acceleration force of the fourth spring to the hammer core is basically the same as the design of the acting force of the releasing block to the hammer core when the releasing block is not separated from the limiting block; the pressure action time of the hammer core to the ground is prolonged by the counter acceleration force; when the floor hammer is lifted by a worker, the driving motor stops working; the release block gradually restores to the original position under the action of the third spring and the protrusion on the flywheel; the hammer core is gradually restored to the original position under the action of the second spring; the limiting block is restored to the original position under the action of the fifth spring; the third rotating shaft moves towards the direction far away from the driving shaft under the action of the restoring force of the sixth spring; thereby restoring the contact point of the second gear and the second bevel gear to the original position.

The third rotating shaft 63 is nested in the driving shaft 70; the circular sleeve 48 is arranged on the driving shaft 70, and four sixth springs 54 are arranged between the circular sleeve 48 and the third rotating shaft 63; the first gear 43 and the second bevel gear 46 are mounted on the third rotating shaft 63; the second gear 44 is mounted on the second rotating shaft 40; one end of the second rotating shaft 40 is provided with a first bevel gear 38; the second gear 44 meshes with a second bevel gear 46; the third gear 53 is installed at one end of the first rotating shaft 39 and is engaged with the first gear 43; the third bevel gear 50 is mounted on the first rotating shaft 39 through a bearing, and the third bevel gear 50 is meshed with the first bevel gear 38; the support ring 37 is installed at one end of the third bevel gear 50; three connecting rods 49 are mounted at one end of the support ring 37; the three fifth gears 57 are respectively mounted on the three connecting rods 49; a fourth gear 56 is mounted on the other end of the first rotating shaft 39; the fourth gear 56 meshes with three fifth gears 57, and the three fifth gears 57 mesh with internal teeth on the drive ring 36; the driven shaft 72 is mounted on the drive ring 36; when the driving shaft 70 rotates, the circular sleeve 48 is driven to rotate, the circular sleeve 48 drives the third rotating shaft 63 to rotate under the action of the sixth spring 54, and the rotating speed of the third rotating shaft 63 is lower than that of the driving shaft 70; the driving shaft 70 is in threaded connection with the third rotating shaft 63; rotation of the drive shaft 70 causes the third shaft 63 to move, and rotation of the third shaft 63 causes the second bevel gear 46 and the first gear 43 to rotate; the third bevel gear 50 rotates to drive the second gear 44 to rotate; the second gear 44 rotates to drive the second rotating shaft 40 to rotate; the second rotating shaft 40 rotates to drive the first bevel gear 38 to rotate; the first bevel gear 38 drives the third bevel gear 50 to rotate; the third bevel gear 50 rotates to drive the supporting ring 37 to rotate; the support ring 37 rotates to drive the three connecting rods 49 to rotate around the axis of the first rotating shaft 39; the three connecting rods 49 rotate to drive the three fifth gears 57 to rotate around the axis of the first rotating shaft 39; the three fifth gears 57 rotate to drive the driving ring 36 to rotate; meanwhile, the first gear 43 rotates to drive the third gear 53 to rotate; the third gear 53 rotates to drive the first rotating shaft 39 to rotate; the first rotating shaft 39 rotates to drive the fourth gear 56 to rotate; the fourth gear 56 rotates to drive the three fifth gears 57 to rotate; the three fifth gears 57 rotate to drive the driving ring 36 to rotate; the drive ring 36 rotates to rotate the driven shaft 72. In the invention, the third rotating shaft 63 moves while rotating, the third rotating shaft 63 drives the second bevel gear 46 to move during the movement, and the outer diameter of the second bevel gear 46 continuously changes, so that the rotating speed of the second gear 44 meshed with the second bevel gear 46 continuously changes while the second bevel gear 46 rotates during the movement; the speed change mechanism 6 designed by the invention has the function of adjusting the torque of the driven shaft 72, and can drive the flywheel 13 to work through a motor with smaller power; thereby reducing the overall weight of the floor hammer.

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 plane and the limiting block 26 is larger; allowing the stop block 26 to be easily disengaged from the release block 28. The third limiting ring 52 limits the first gear 43; the first limiting ring 41 limits the third gear 53; the fourth fixing ring 55 has a limiting effect on the fourth gear 56; the fifth fixing ring 58 serves to limit the fifth gear.

The specific implementation mode is as follows: in the use process of the floor hammer, the four sixth springs 54 are in a free telescopic state; the first spring, the second spring 22, the third spring 25, the fourth spring 32 and the fifth spring 34 are in a free telescopic state; the meshing point of the second gear 44 and the second bevel gear 46 is at the maximum of the diameter of the second bevel gear 46; when workers need to correct the floor, the floor is hammered by the floor hammer, and the hammer core 3 can move upwards under the action of the reaction force of the ground; the hammer core 3 moves upwards to drive the fourth spring 32 to compress upwards; the second spring 22 is compressed upward; the fourth spring 32 will push the release block 28 to move upwards; at this time, the third spring 25 is gradually pulled apart; the limiting block 26 moves into the limiting groove; the fifth spring 34 is compressed; when the resistance of the limiting block 26 to the releasing block 28 is smaller than the pushing force of the fourth spring 32 to the releasing block 28, the fourth spring 32 pushes the releasing block 28 away, so that the releasing block is separated from the constraint of the limiting block 26; as shown in fig. 14a, if there is no impact of the flywheel, then the pressure on the ground decreases rapidly when the release mass is released. As shown in b of fig. 14, after the release block is released, the flywheel is collided by the flywheel, and when the arc-shaped groove 12 on the release block 28 is contacted with the projection 11 during the upward movement of the release block, the flywheel 13 drives the projection 11 mounted on the lower side thereof to rotate and hit the groove wall of the arc-shaped groove 12; in the process, downward pressure is applied to the release block 28 to enable the release block 28 to move downwards, so that the working time of the hammer core 3 on the ground is prolonged; the design of the release block reduces noise; simultaneously, the downward movement of the 28 blocks is released, and simultaneously, the downward pressure is applied to the hammer core 3 through the fourth spring 32; 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, and the pressure of the hammer core 3 to the ground is increased through the acceleration force; when the floor hammer is lifted by a worker, the driving motor 4 stops working; 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 limiting block 26 is restored to the original position under the action of the fifth spring 34; the third rotating shaft 63 moves in a direction away from the driving shaft 70 by the restoring force of the sixth spring 54; thereby restoring the contact point of the second gear 44 and the second bevel gear 46 to the original position.
