[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0022] Refer toFigures 1-4 , an embodiment of the utility model provides a quick-change fixture, which comprises a base 1, a pressing block 2, and a quick-change part. A pair of cavities 3 distributed left and right are arranged inside the base 1. The pressing block 2 is slidably connected to the inside of the cavity 3. A middle column 4 is arranged inside the base 1. A spring 5 is slidably connected to the inner surface of the middle column 4. A chute 6 is arranged inside the base 1. The chute 6 extends to the cavity 3. The cavity 3 is a U-shaped groove. A second buckle 7 is installed on the upper surface of the pressing block 2. The second buckle 7 is slidably connected to the chute 6. A groove 8 is arranged inside the pressing block 2. The groove 8 is slidably connected to the spring 5. The quick-change part comprises a quick-change plate 10 and a first buckle 11. The first buckle 11 is installed on the lower surface of the quick-change plate 10. The first buckle 11 slides inside the chute 6. The first buckle 11 and the second buckle 7 are engaged with each other. The first buckle 11 and the second buckle 7 are wedge-shaped bodies. Four positioning columns 13 distributed in a rectangle are fixedly connected to the upper surface of the base 1. The quick-change plate 10 is slidably connected to the positioning columns 13. A first mounting hole 9 is arranged inside the second buckle 7 and extends to the inside of the pressing block 2.
