A connection apparatus for an artificial model comprises a resilient device; and a post device. The resilient device further comprises a fixing disk, a hollow shaft, a sleeve, a plurality of balls, an elastic element, an upper cover, and a push lever. The hollow shaft extends upright from the fixing disk, and the sleeve fits with the hollow shaft in a way of being disposed outside the hollow shaft. The balls are inserted into pierced apertures on the hollow shaft respectively and are retained between the hollow shaft and an annular projection of the sleeve. The elastic element is disposed in the sleeve and urges the hollow shaft to fit with the sleeve with an aid of the balls. The push lever is disposed between the sleeve and the upper cover to be adjusted by a bolt at an end of the push lever. The post device further comprises a flange and an upright post. The upright post with a round top and a recess ring to be inserted into the hollow shaft with the round top thereof passing over the balls smoothly and the recess ring thereof engages with the balls such that the resilient device can join with the post device. Once the push lever is pushed and the slant parts next to the neck part thereof press the sleeve to slide toward the fixing disk, the annular projection section of the sleeve may slide away the balls to release the balls from the recess ring such that the post is taken out from the hollow shaft to disengage the post device from the resilient device.
