[0027] See also Figures 1 to 5 The utility model provides a technical solution: a driving shaft rod 1, characterized in that: the top of the driving shaft rod 1 is fixedly connected to the driving shaft seat 2, one end of the driving shaft rod 1 is located directly below the driving shaft seat 2, a cavity is provided on the top of the driving shaft seat 2, and the motor output end 3 is movably connected in the cavity, and a plurality of sliders 4 are evenly welded on the surface of the motor output end 3, the bottom of the slider 4 is flush with the bottom of the motor output end 3, the height of the slider 4 is greater than the height of the cavity at the top of the driving shaft seat 2, and a sliding groove 13 adapted to the slider 4 is provided on the cavity surface of the driving shaft seat 2. When the motor output end 3 is inserted into the cavity at the top of the driving shaft seat 2 and the slider 4 is inserted into the sliding groove 13, the motor output end 3 can drive the driving shaft seat 2 to rotate through the slider 4 when rotating, thereby driving the driving shaft rod 1 to rotate, ensuring that the rotation direction of the motor output end 3 is tightly engaged with the driving shaft seat 2;

[0028] The outer wall of the drive shaft seat 2 is provided with four limiting through holes 7, and the limiting through holes 7 vertically penetrate the outer wall of the drive shaft seat 2 to the internal cavity of the drive shaft seat 2. The motor output end 3 is provided with four limiting grooves 12 adapted to the limiting through holes 7. When the slider 4 on the surface of the motor output end 3 is aligned with the sliding groove 13 in the top cavity of the drive shaft seat 2, the limiting groove 12 is aligned with the limiting through hole 7 and is slidably connected to the limiter 5; the limiter 5 includes a limiting block 501, and the outer wall of the limiting block 501 is sleeved with a reset spring 502, one side of the reset spring 502 is vertically fixed to the outer wall of the drive shaft seat 2, and the other side is fixedly connected to the limiting plate 503, and the other side of the limiting plate 503 is fixedly connected to the limiting inclined block 504;

[0029] An external thread 11 is provided at the lower end of the outer wall of the driving shaft seat 2, and the upper end of the external thread 11 is located below the limiting through hole 7. The outer side of the external thread 11 is spirally connected to the limiting sleeve 6, and the inner boundary position of the limiting sleeve 6 protrudes from the outer side of the limiting plate 503. When the limiting sleeve 6 is screwed upward along the external thread 11, the inner boundary of the limiting sleeve 6 contacts the lower inclined surface of the limiting inclined block 504 when reaching the height of the limiter 5, and applies pressure to the limiting inclined block 504, so that the limiting inclined block 504 moves inward, and the limiting block 501 is clamped into the limiting groove 12 on the motor output end 3, ensuring that the motor output end 3 and the driving shaft seat 2 are tightly engaged and not easy to be separated;

[0030] A limiting hole 19 is formed on the limiting sleeve 6, and a limiting hole 2 10 is formed at a corresponding position of the drive shaft seat 2.

The limiting hole 2 10 is a non-through hole on the drive shaft seat 2, and the inner wall of the limiting hole 2 10 is provided with an internal thread matched with the fixing screw 8. When the limiting sleeve 6 is screwed to At the top, screw the fixing screw 8 into the second limit hole 10, fix the limit sleeve 6 on the outside of the limiter 5, so that the limiter 5 does not loosen, ensuring the engagement effect between the motor output end 3 and the drive shaft seat 2; when the motor stops working, screw the fixing screw 8 out of the second limit hole 10, screw the limit sleeve 6 to the bottom of the limiter 5, the reset spring 502 on the limiter 5 loses pressure and restores its original length, driving the limit block 501 to move out of the limit groove 12, thereby releasing the restriction on the motor output end 3.

At this time, the limiting hole 1 9 is aligned with the limiting hole 2 10, and the fixing screw 8 is inserted into the limiting hole 1 9 and the limiting hole 2 10, and tightened with the limiting hole 2 10, thus completing the connection between the motor output terminal 3 and the driving shaft seat 2, so that the motor output terminal 3 and the driving shaft are tightly engaged and not easy to disengage; screw the fixing screw 8 out of the limiting hole 2 10, screw the limiting sleeve 10 downward to the bottom of the stopper 5, and then pull the motor input terminal 3 out of the upper cavity of the driving shaft seat 2, so that the motor output terminal 3 and the driving shaft can be detached.
