Abstract: A coupling device for an artificial model includes a male joining part, a female joining part and an insertion member. The male and female joining parts have a base disk attached with a front positioning plate and a rear lock plate respectively. The insertion member further includes an insert head, an adjustable bolt, a first elastic body, a cap, a pin, a ball, a second elastic body and a setscrew. The insertion member is inserted into the male and female joining parts such that the male joining part can open any angles with respect to the female joining part smoothly.

Abstract: A coupling device for an artificial model includes a male joining part and a female joining part, which is joined to the male joining part tightly. The male joining part has the front positioning plate thereof providing a central circular protrusion, the insertion member thereof is composed of an insert head, a pin, an adjustment bolt, an elastic body and a covering cap with the insert head having a conical shape and an elongated flat part at the bottom thereof with the pin being inserted into the insert head along a radial direction of the insert head and passing through an axis of the insert head to form a shape of cross, and a hollow center thereof has a shape corresponding to the elongated flat part of the insert head such that the elongated flat part of the insert head can fit with the hollow center after being inserted into the hollow center with the adjustment bolt passing through the cap and the elastic body before engaging with the bottom of insert head.

Abstract: A waist connection apparatus for an artificial model comprises an upper and a lower bases respectively, and an upper and a lower engaging disks respectively. The upper and the lower engaging disks are fastened to the upper and the lower bases respectively. The upper and the lower disks provide detachable connecting parts such that the upper and the lower parts of the model can be joined together or separated apart easily. Hence, the waist connection apparatus makes the model possible to be hung up, lean to one side, and many other postures as desired by the need of exhibition. Furthermore, the waist connection apparatus can fit any size of the model as soon as a proper sized waist connection apparatus is replaced.

Abstract: A connection apparatus for an artificial model includes a resilient device and a post device. The resilient device has a hollow shaft extending upward from the fixing disk thereof to fit with a sleeve disposed outside the hollow shaft. A plurality of balls are attached to the hollow shaft and retained between the hollow shaft and the sleeve. The post device further includes a flange and an upright post. The upright post is inserted into the hollow shaft with the round top thereof passing over the balls such that the resilient device can join with the post device. Once the push lever is pushed with the slant parts thereof pressing the sleeve to slide the fixing disk forward, the annular projection section of the sleeve may slide away the balls to release the balls from the recess ring on the push rod such that the post is taken out from the hollow shaft to disengage the post device from the resilient 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.

Abstract: An arm connection apparatus for an artificial model comprises two flat bases, a lock disk, a lock bolt, and a fixing disk. Each base has a recess hole with a contour composed of circular arc parts to join with a lock hole of the lock disk and a polygon lock part on the lock bolt such that an arm of the artificial model can be detachably connected to a shoulder part thereof easily and firmly. Next, the arm can be arranged to connect with the shoulder part in different positions by way of a changeable engagement between the lock hole and the polygon lock part. Moreover, it is possible to adjust the orientation of the lock hole by way of changing the angular position of the lock disk during being attached to the base to make the arm be a point of load while the model is hung up.
