The other end of the pull rope 16 is fixedly connected to the pedal 18. In the present embodiment, when the motor seat needs to be rotated, the assembler steps on the pedal 18, and the pedal 18 pulls the pull rope 16 downward.

[0036] Working principle: When the utility model is in use, first adjust the position of the fixing hole 10 according to the position of the motor seat mounting hole that needs to be assembled, and turn the first knob 4 according to the horizontal distance between the motor seat mounting holes. The first knob 4 drives the horizontal positive and negative screw rod 3 to rotate, and the horizontal positive and negative screw rod 3 rotates so that the two threaded blocks 7 thereon move, thereby adjusting the fixing plate 9 thereon to a suitable position, and adjusting the horizontal fixing hole 10 to a suitable distance. Then, according to the vertical distance between the motor seat mounting holes, turn the second knob 6, and the second knob 6 drives the vertical positive and negative screw rod 5 to rotate, and the vertical positive and negative screw rod 5 rotates so that the two threaded blocks 7 thereon move, thereby adjusting the fixing plate 9 thereon to a suitable position, and adjusting the vertical fixing hole 10 to a suitable distance. Then, align the mounting hole of the motor seat with the fixing hole 10, and the motor seat is assembled. The device is fixed and assembled, so that it is suitable for motor seats of different sizes, which improves the applicability of the device. When the motor seat needs to be rotated, the assembler steps on the pedal 18, and the pedal 18 pulls the pull rope 16 downward, and the other end of the pull rope 16 pulls the cross plate 15, so that the cross plate 15 drives the limit rod 14 to move downward, so that the limit rod 14 is disengaged from the inside of the limit hole 13, and the limit plate 12 is released. The fixed cylinder 2 is rotated to rotate the motor seat. After rotating to a suitable position, the force on the pedal 18 is stopped, and the first spring 20 resets to drive the pedal 18 to reset, and the second spring 21 resets to drive the cross plate 15 and the limit rod 14 to reset, so that the limit rod 14 is inserted into the limit hole 13, and the limit plate 12 is limited by the limit rod 14, thereby preventing the fixed cylinder 2 from rotating autonomously.
