[0025] It should be noted that the fixing seat 10 is set to an external hexagonal shape, which can enable it to withstand greater torque and is not easily damaged, thereby facilitating fixation with external tools. The external tool can be set to a wrench, and the fixing seat 10 can be driven to rotate by the external tool, so that the fixing seat 10 can drive the fixed baffle 1 and the thrust baffle 2 to move. When the fixed baffle 1 and the thrust baffle 2 move, the pulley can be disassembled through the thrust baffle 2.

[0026] In an optional embodiment: a plurality of first movable holes 6 are formed in a circular array on the fixed baffle plate 1 , a plurality of second movable holes 7 are formed in a circular array on the thrust baffle plate 2 , and the fixed screw 3 is disposed in the first movable hole 6 and the second movable hole 7 .

[0027] It should be noted that, by setting the first movable hole 6 and the second movable hole 7, the position of the fixed screw 3 can be adjusted so that it can disassemble motor pulleys of different specifications, with a wider range of applications. At the same time, the fixed screw 3 can be adjusted closer to the motor pulley, so that the thrust baffle 2 is not easily deformed and can withstand greater pulling force.

[0028] In an optional embodiment: an adjustment mechanism for adjusting the fixed screw 3 is provided on the side of the fixed baffle 1, the adjustment mechanism includes a fixed ring 12, an adjustment sleeve 13, a first hinge block 14, a movable seat 15, a push rod 19 and a second hinge block 20, the fixed ring 12 is fixedly connected to the side of the fixed baffle 1, the adjustment sleeve 13 is movably installed on the fixed ring 12, the first hinge block 14 is arranged in a ring array on the surface of the adjustment sleeve 13, the push rod 19 is movably installed on the first hinge block 14, the second hinge block 20 is fixedly connected to the side of the movable seat 15, and one end of the push rod 19 is movably installed on the second hinge block 20.

At this time, the motor pulley is located between the fixed baffle 1 and the thrust baffle 2, and is fixed on the fixed seat 10 by an external tool. The external tool can drive the top cone screw 9 to rotate through the fixed seat 10, so that one end of the top cone screw 9 can be tightly pressed against the output shaft of the motor. After the end of the top cone screw 9 is tightly pressed against the output shaft of the motor, the top cone screw 9 can drive the fixed baffle 1 to move on the top cone screw 9 when it rotates, and the fixed baffle 1 can drive the thrust baffle 2 to move when it moves. When the thrust baffle 2 moves, the pulley is subjected to the outward force applied by the thrust baffle 2, and then the pulley can be removed from the output shaft of the motor.
