[0056] like Figure 3 As shown, guide grooves 1100 can be respectively provided on both sides of the frame 110, and guide wheels 1130 can be respectively provided on both sides of the second movable plate 113, so that the guide wheels 1130 are respectively embedded in the corresponding guide grooves 1100 to achieve a slidable connection between the second movable plate 113 and the frame 110. The top rod 12 can be vertically connected to the second movable plate 113, and the top rod 12 can be connected to the second movable plate 113 by welding or interference fit.

The traction rope 112 is connected to the second movable plate 113 to drive the second movable plate 113, and there is no need to use additional screws to connect the traction rope 112 and the second movable plate 113, so that the connection between the two is simpler.

[0057] like Figure 3As shown, optionally, the telescopic assembly 111 includes a first pulley 1111, a semi-open pulley bracket 1112 and a telescopic rod 1110, the first pulley 1111 and the pulley bracket 1112 are pivotally connected, the traction rope 112 is embedded in the first pulley 1111 in the opening direction of the pulley bracket 1112, and the pulley bracket 1112 is fixed to the telescopic rod 1110. In this way, there is no obstruction when the traction rope 112 is embedded in the first pulley 1111, which can facilitate the traction rope 112 to be embedded in the first pulley 1111. The pulley bracket 1112 can be fixed to the left end of the telescopic rod 1110, and the telescopic rod 1110 can drive the pulley bracket 1112 and the first pulley 1111 to move when the telescopic rod 1110 is extended.

[0059] like Figure 3 As shown, optionally, the telescopic assembly 111 is arranged on the top of the frame 110. In this way, the telescopic assembly 111 will not occupy the lifting space of the second movable plate 113, so that the lifting space of the second movable plate 113 is larger.

[0060] Please also refer to Figure 1 and Figure 3 Optionally, the moving direction of the first movable plate 10 and the moving direction of the second movable plate 113 are perpendicular to each other. With this arrangement, the push rod 12 and the connecting assembly 13 can move in at least two directions (for example, in a direction parallel to the Y axis or in a direction parallel to the Z axis), thereby improving the flexibility of the push rod 12 and the connecting assembly 13 when aligning with the impeller 3 and the rotating shaft 2.

[0061] like Figure 1As shown, optionally, the fan impeller disassembly tool further includes a support 14, the rotating shaft 2 is placed on the support 14, and the impeller 3 is located between the lifting assembly 11 and the support 14.

With such an arrangement, the height of the lifting mechanism 17 can be adjusted according to different diameters of the impeller 3, and at the same time, the friction between the lifting mechanism 17 and the impeller 3 can be increased when the lifting mechanism 17 and the impeller 3 are pressed against each other, so as to prevent the impeller 3 from sliding when the rotating shaft 2 is pushed out. The lifting mechanism 17 can be a scissor-type electric or hydraulic lifting platform. The lifting direction of the lifting mechanism 17 can be parallel to the Z axis. The lifting mechanism 17 can be placed on the first movable plate 10.

The plug rod 160 can be connected to the bracket 16 by screwing or welding. The edges of the two end faces of the impeller 3 can be clamped between the two plug rods 160 of each bracket 16.

[0065] Please also refer to Figures 1 to 3When using the fan impeller disassembly tool, the impeller 3 with the rotating shaft 2 can be hoisted to a suitable position first, so that the support 14 contacts the rotating shaft 2, and the impeller 3 contacts the lifting mechanism 17 and the two brackets 16. Slide and adjust the first movable plate 10 and the second movable plate 113, so that the connecting assembly 13 and the impeller 3 are aligned and connected, and the push rod 12 and the rotating shaft 2 are aligned and pressed against the rotating shaft 2. Finally, start the carrier 15, so that the carrier 15 pushes the push rod 12 to push out the rotating shaft 2 in the negative direction parallel to the X-axis.

[0066] After the rotating shaft 2 is ejected, the impeller 3 can be transported away by the carrier 15. When the diameter of the impeller 3 is different, the distance between the two brackets 16 and the height of the lifting mechanism 17 can be adjusted. In order to further prevent the impeller 3 from sliding when the rotating shaft 2 is ejected, a hook can be provided on the front side of the first movable plate 10 (the front side is the negative side of the first movable plate 10 on the X-axis) to further fix the impeller 3.
