[0020] The utility model will be further explained in connection with the drawings.

[0021] Please refer to Figures 1 to 7 The utility model provides an embodiment:

[0022] Please refer to Figure 1 And Figure 3 A kind of excavator quick-change device, including a base 1 and the hydraulic jack 2 of setting in the middle part of base 1, base 1 is placed with the first moving plate 3 capable of moving on base 1, first moving plate 3 is set on the hydraulic jack 2, first moving plate 3 is fixed with rail groove support 4, rail groove support 4 is placed with the second moving plate 5 capable of moving on rail groove support 4.

[0023] Please refer to Figure 1 、 Figure 3 And Figure 4The base 1 is provided with a groove 6 on both sides, and the lower surface of the first moving plate 3 is fixed with a roller 7 for moving in the groove 6. When the roller 7 moves in the groove 6, the first moving plate 3, the rail groove support 4 and the second moving plate 5 are driven to move.

[0024] Please refer to Figure 1 、 Figure 4 and Figure 5 , the rail groove support 4 includes a pair of guide rails with corners, and one end of the guide rail is grounded. The lower surface of the second moving plate 5 is fixed with a sliding wheel 8 for moving in the guide rail. When the sliding wheel 8 moves in the guide rail, the second moving plate 5 and the excavator bucket 11 placed on the second moving plate 5 are driven to move, adjusting the position of the excavator bucket 11.
