The fixing column 210 is fixedly connected to the outer end of the first telescopic spring 209.

[0035] The movable tube 201 is used to support the first gear 202, the second gear 203 and the third gear 204. The first gear 202, the second gear 203 and the third gear 204 are respectively used to drive the fourth gear 205, the fifth gear 206 and the sixth gear 207 to rotate. The fourth gear 205, the fifth gear 206 and the sixth gear 207 are respectively used to drive the output shaft 103 to rotate. The fixing hole 208 is used to place the fixing column 210. The first telescopic spring 209 is used to reset the fixing column 210. The fixing column 210 is used to fix the movable tube 201 and the rotating shaft 102.

[0036] The motor assembly also includes a starting gear 104;

[0037] The rotating shaft 102 is sleeved at the upper end of the housing 101, the output shaft 103 is sleeved at the central position of the housing 101, the starting gear 104 is sleeved at the outer surface of the outer end of the output shaft 103, and the rotating shaft 102 and the output shaft 103 respectively penetrate the housing 101 and extend outwards;

[0038] The rotating shaft 102 is used to drive the movable tube 201 to rotate, the output shaft 103 is used to drive the starting gear 104 to rotate, and the starting gear 104 is used to drive the generator to rotate;

[0039] The first gear 202 is meshed with the fourth gear 205, the second gear 203 is meshed with the fifth gear 206, the third gear 204 is meshed with the sixth gear 207, and the number of teeth of the first gear 202 is the same as the number of teeth of the sixth gear 207, the number of teeth of the second gear 203 is the same as the number of teeth of the fifth gear 206, the number of teeth of the third gear 204 is the same as the number of teeth of the fourth gear 205, the number of teeth of the first gear 202 is greater than the number of teeth of the second gear 203, and the number of teeth of the second gear 203 is greater than the number of teeth of the third gear 204;

[0040] When the first gear 202 and the fourth gear 205 are meshed, the speed of the output shaft 103 increases while the speed of the rotating shaft 102 remains unchanged. When the second gear 203 and the fifth gear 206 are meshed, the speed of the rotating shaft 102 is the same as the speed of the output shaft 103. When the third gear 204 and the sixth gear 207 are meshed, the speed of the output shaft 103 decreases while the speed of the rotating shaft 102 remains unchanged.

[0041] The movable tube 201 is sleeved on the outer surface of the rotating shaft 102, and the fixing hole 208 is opened relative to the fixing column 210;

[0042] When the fixing column 210 is located inside the fixing hole 208, the rotation of the rotating shaft 102 can drive the movable tube 201 to rotate;

[0043] Working principle: When the rotation speeds of the rotating shaft 102 and the output shaft 103 need to be kept at the same, an inward force is applied to the fixed column 210 to move the fixed column 210 inward. The inward movement of the fixed column 210 compresses the first telescopic spring 209 to generate elastic force, and the fixed column 210 moves out from the fixing hole 208. At this time, a moving force is applied to the movable tube 201 to move the movable tube 201 on the outer surface of the rotating shaft 102. When the second gear 203 and the fifth gear 206 are engaged, the fixed column 210 moves to the inside of the fixing hole 208 at the middle position, so that the rotation speed of the output shaft 103 and the rotation speed of the rotating shaft 102 can be kept the same.

[0044] When the rotation speed of the output shaft 103 needs to be adjusted, the above steps are repeated until the first gear 202 and the fourth gear 205 are meshed, or the third gear 204 and the sixth gear 207 are meshed.

[0047] The protection tube 301 is fixedly connected to the upper end of the outer end of the shell 101, the second telescopic spring 302 is fixedly connected to the two ends of the outer surface of the protection tube 301, the movable column 303 is fixedly connected to the outer end of the second telescopic spring 302, the placement groove 304 is opened at the outer end of the movable tube 201, the rotating disk 305 is located in the inner position of the placement groove 304, and the fixing bolt 306 is fixedly connected to the central position of the outer surface of the rotating disk 305;

[0048] The protection tube 301 is used to protect the outer ends of the movable tube 201 and the rotating shaft 102. The second telescopic spring 302 is used to reset the movable column 303. The movable column 303 is used to drive the fixed column 210 to move. The placement groove 304 is used to place the rotating disk 305. The rotating disk 305 is used to support the fixing bolt 306.

[0050] When the rotating shaft 102 and the movable tube 201 rotate at the outer end of the rotating disk 305, the rotating disk 305 is kept fixed under the drive of the fixing bolt 306;

[0051] Working principle: when it is necessary to adjust the speed of the output shaft 103, an inward force is applied to the movable column 303 to make the movable column 303 move inward, and the inward movement of the movable column 303 drives the fixed column 210 to move inward, and then a moving force is applied to the fixing bolt 306 to make the fixing bolt 306 drive the movable tube 201 to move, thereby driving the movable tube 201 to move, thereby adjusting the speed of the output shaft 103, and when the adjustment is completed, the fixing bolt 306 is fixed to the outer end position of the protective tube 301 by the nut. At this time, when the movable tube 201 and the rotating shaft 102 rotate, the movable tube 201 and the rotating shaft 102 rotate inside the protective tube 301, and will not drive the turntable 305 to rotate, so that the fixing bolt 306 remains stationary, thereby protecting the movable tube 201 and the rotating shaft 102, and preventing them from contacting the outside world during high-speed rotation.
