A plurality of groove gears 61 are equidistantly fixed on the movable shaft 6, two sides of each groove gear 61 are normal tooth openings, and a groove 611 is formed in the middle of each groove gear 61 and used for adsorbing scrap iron and other impurities. The two ends of the movable shaft 6 are respectively fixed with a bearing 4, the two bearings 4 are respectively fixed on a threaded cover 65, and the threaded covers 65 are respectively screwed on threaded openings at the two sides of the gear box 1; the two threaded caps 65 are not of the same size, but the larger threaded cap 65 must be larger than the recessed gear 61. The screw cap 65 is constructed to facilitate the removal of the entire movable shaft 6 and then to clean the movable shaft 6 and the gear 61 recessed therein and the foreign matter in the groove 611 thereof. The other side of the screw cover 65 is also fixed with a fixing bracket 63, the fixing bracket 63 comprises a fixing circular truncated cone 631, a fixing foot 632 and a screw 634, the middle of the fixing circular truncated cone 631 is provided with a circular opening 633, the screw 634 is screwed into the fixing circular truncated cone 631 from the side, and the screw 634 penetrates through one side of the fixing circular truncated cone 631 and is used for fixing an object penetrating through the circular opening 633 of the fixing circular truncated cone 631. The loose axle 6 is hollow structure, and inside is hollowed out, runs through a electrically conductive thin rod 64 in it, and electrically conductive thin rod 64 both ends expose gear box 1, and is fixed respectively on the circular opening 633 of fixed bolster 63, and wire 7 has still been twined respectively to the end on the thin rod 64 both sides of wire, and the other one end of two wires 7 is connected on the positive and negative pole of electronic box 2, is provided with switch 21 on electronic box 2, can let electronic box 2 supply power for equipment through pressing switch 21. Each gear on the driving shaft 3, the driven shaft 5 and the movable shaft 6 in the gear box 1 corresponds to each other, and the gears are meshed together in a staggered mode.

The method comprises the following specific operations: when the gear box 1 is needed to act, only the pinion 51 externally connected to the driving shaft 3 needs to be connected with transmission equipment needing to be connected, the transmission equipment needs to operate at low power, the linear speed of the rotation of the gear cannot be too high, otherwise, iron chips adsorbed on the groove gear 61 are thrown out of the groove 611 on the groove gear 61 due to too high eccentricity, or other transmission equipment is not needed, the pinion 51 externally connected to the gear box is selected to be rotated by hand, when the gear box 1 works, the power button 21 is pressed down, the electric box 2 is opened, and the electric box 2 is used for supplying power for the filtering equipment. When the gear box 1 stops working, the external pinion 51 on the driving shaft 3 is driven to rotate by the external transmission equipment, the rotation of the pinion 51 drives the whole driving shaft 3 to rotate, and because the gears of the corresponding gears on each shaft in the gear box 1 are meshed with each other, the rotation of the large gear 31 on one driving shaft 3 can drive the rotation of the gears on the whole gear box 1. While impurities in the gear box 1, such as iron filings, are mainly attached to lubricating oil in the gear box 1, and the lubricating oil is brought to various places in the gear box 1 along with the transmission of the gears, at this time, the filtering device can work, and the working principle of the filtering device is electromagnetism, wherein the electromagnetism is that a straight metal wire passes through current, and then a circular magnetic field is generated in the space around the wire. The larger the current flowing in the wire is, the stronger the generated magnetic field is, the magnetic field is circular and surrounds the wire, and considering that the gear is also a metal product, if the current is too large, the too strong magnetic field generated by the current can influence the normal operation of the gear in the gear box 1, and the impurity iron chips contained in the gear box 1 are generally small in mass, so that the voltage released in the electric box 2 does not need to be large, and the electric energy can be saved. When the power is on, the conductive thin stick 64 can emit a weak magnetic field to surround the periphery of the conductive thin stick 64, the movable shaft 6 which is wrapped by the conductive thin stick 64 can be wrapped by the small magnetic field, when iron filings are transmitted to the movable shaft 6 along with lubricating oil, the iron filings can be adsorbed on the movable shaft 6, in order to place the iron filings adsorbed by the gear on the movable shaft 6 to influence the normal operation of the movable shaft 6, the groove gear 61 is arranged on the movable shaft 6, a groove 611 is arranged in the middle of the groove gear 61 compared with the normal gear, the groove 611 can be used for temporarily storing the iron filings, when the iron filings are accumulated to a certain amount, the whole movable shaft 6 can be disassembled and cleaned, two threaded covers 65 are arranged at two ends of the whole movable shaft 6, the two threaded covers 65 are different in size, one side is larger and the other side is smaller, the diameter of the larger threaded cover 65 is certain larger than that of the groove gear 61, and the design significance is that the whole, when the disassembly is needed, the movable shaft 6 can be taken out of the gear box 1 only by unscrewing the threaded cover 65 from the larger side of the threaded cover 65, and in addition, the wires 7 on the conductive thin stick 64 cannot be disassembled, otherwise, the conductive thin stick 64 is not electrified, and a magnetic field cannot exist. The groove 611 can then be cleaned and finally the movable shaft 6 can be mounted back in the same way.
