[0019] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a toughness detection tooling for 3D printing composite materials includes a material fixing end; the material fixing end 1 is fixedly connected to the left end of the detection material belt 3, and the detection material belt 3 extends into the screw sleeve 5 along the hub 4 installed at the center of the fixed composite wheel 7. The end of the detection material belt 3 extending into the screw sleeve 5 is fixedly connected to the hub 4 at the center of the active composite wheel 6, and the screw sleeve 5 is synchronously connected to the hub 4 at the center of the active composite wheel 6. The fixed composite wheel 7 and the active composite wheel 6 are both placed in the detection water bucket. Among them, the material fixing end 1, as the fixing end of the detection material belt 3, can cooperate with the hub 4 at the center of the active composite wheel 6 to complete the horizontal stretching process. During the stretching process, the detection material belt 3 can cooperate with the active composite wheel 6 to complete the detection stretching action along the guiding direction of the screw sleeve 5. This process can utilize the water bucket structure to limit the placement positions of the fixed composite wheel 7 and the active composite wheel 6, and through the water filled inside the water bucket, to simulate the toughness influence of different environments and different aqueous solutions on the detection material belt 3.

The root of the limit plug 12 and the extension arm 11 are of an integral connection structure, and the root of the extension arm 11 and the hub 4 are of an integral connection structure. Among them, the active composite wheel 6 makes a rotary feed movement along the extension direction of the screw sleeve 5. During the rotation of the active composite wheel 6, the distance from the fixed composite wheel 7 is extended. Thereby further stretching the detection material belt 3.
