Claims

[Scope of Claim for Utility Model Registration] (1) In a mannequin for dental training in which the articulator unit 1 is attached to the head unit 2, the fixed shaft 3 attached to the top of the articulator unit 1 is used.
A groove 4 of a constant width is provided around the tip of the head unit 2, and a shaft hole 5 for the fixed shaft 3 is provided in the center of the head base 13 of the head unit 2. On the side, a pressing member 6 having a shaft hole 5' in the center is attached so as to be movable back and forth by an eccentric wheel 7 attached to the shaft hole 5'. A disc 9 having an arc-shaped notch 8 is attached concentrically to the eccentric wheel drive shaft 10, and the arc-shaped notch 8 is provided at the front end of the pressing member 6.
' exists, and with the lever 11 attached to the eccentric wheel 7 brought to the open position, the pressing member 6 moves backward, and the notch 8' of the pressing member 6 pushes the fixed shaft 3 out of the shaft hole 5. With the notch 8 of the disc 9 located outside the shaft hole 5 of the fixed shaft 3 along the edge of the shaft hole 5, and the lever 11 brought to the fixed position, The pressing member 6 moves forward and the notch 8'
This acts to press and fix the fixed shaft 3 forward in the shaft hole 5, and the notch 8 of the disc 9 is shifted from the shaft hole 5, so that the circumferential portion 12 of the disc 9 fits into the groove. 4. An attachment/detachment device for a mannequin articulator for dental training, characterized in that the device is configured to be located within a mannequin articulator for dental training. (2) The device according to claim 1, wherein a backing plate 14 is attached to the head base 13 along the side surface of the pressing member 6. (3) The device according to claim 1 or 2, wherein the lever 11 is mounted so as to be movable at an angle of 90°. (4) Fixing means 15 for fixing the lever 11 in the open position or fixed position on the head base 13
The device according to any one of claims 1 to 3, characterized in that the device is provided with:
