the inner wall fixedly connected with electro-magnet 15 of roller 14, electro-magnet 15 and force sensing resistor 4 electric connection, the magnetism of the relative face of electro-magnet 15 and magnetic sheet 17 is the same, the structure of magnetic sheet 17 is the loop configuration, the quantity of magnetic sheet 17 is four, the outside elastic connection of electro-magnet 15 has magnetic sheet 17, the inner wall of roller 14 just is close to the outside fixedly connected with gasbag 18 of magnetic sheet 17, the outside fixedly connected with angle frame 19 of roller 14, the material of angle frame 19 is stainless steel material, the quantity of angle frame 19 is four, angle frame 19 evenly distributed is in the outside of roller 14, the outside fixedly connected with pressure ring 16 of angle frame 19, the material of pressure ring 16 is the rubber material, the structure of pressure ring 16 is the torus structure.
The working principle is as follows: when the troweling machine normally works, the motor can drive the shell 6 to rotate, and because the magnetism of the opposite surfaces of the electromagnetic ring 2 on the outer side of the fixed shaft 1 and the magnetic shaft 5 fixedly connected with the inner side of the shell 6 is the same, repulsive force exists between the electrified electromagnetic ring 2 and the magnetic shaft 5, magnetic suspension is formed, the use of a bearing is avoided, the utilization rate of energy when the motor drives the shell 6 to rotate is improved, and energy is saved.
When the troweling machine normally works, the pressure plate 3 is in contact with the ground, the force-sensitive resistor 4 is under the action of pressure, so that the resistance value of the force-sensitive resistor 4 is reduced, the electromagnet 15 is electrically connected with the force-sensitive resistor 4, so that current passes through the electromagnet 15, the electromagnet 15 has magnetism, and the magnetism of the opposite surface of the electromagnet 15 and the magnetic plate 17 is the same, so that the electrified electromagnet 15 repels the magnetic plate 17, the magnetic plate 17 extrudes the air bag 18 along the inner wall of the roller shaft 14, the air in the air bag 18 is extruded, at the moment, the pressure outside the roller shaft 14 is increased, the pressure ring 16 expands, and the angle bracket 19 moves outwards along with the pressure ring 16;

When the concave surface of the concrete floor cannot be smoothed, when the pressure plate 3 passes through the concave surface, the force-sensitive resistor 4 is not acted by pressure, the resistance value of the force-sensitive resistor 4 is increased, so that the current flowing through a circuit disappears, the electromagnet 15 loses magnetism, and the repulsive force to the magnetic plate 17 is lost, so that the magnetic plate 17 returns to the original nominal position under the action of the spring, the angle bracket 19 also contracts under the action of the internal spring, so as to drive the pressure ring 16 to contract, the gas outside the roller shaft 14 is extruded into the air bag 18, the hinge rod 9 loses external extrusion force at the moment, the contact 8 is driven to return to the original height under the action of the internal reset spring 11, the electric contact ring 7 is separated from the contact 8, no current flows through the current variant groove 12 at the moment, the electric current can be changed from solid to liquid, and the wiping blade 13 cannot rotate together with the shell 6 at the moment;
