FIG. 12C is the schematic diagram of a needle gadget. 1230 is the needle tube ceiling, 1235 is the needle top, 1240 is the needle-holding spring, 1245 is the needle shaft, 1255 is the locking notch on the needle tube, 1260 is the needle tube floor, 1250 is the openings on the needle tube, designed to let the needle driver enter the needle tube. FIG. 12D is the bottom view of the automatic acupuncture device. 1225 is the case, 1270 is the needle gadget chamber, 1265 is the needle gadget chamber opening. The fact that 1270 is not exactly in the center of 1265 is to define the insertion direction of the needle gadget. FIG. 12E shows a needle driver 1215, and FIG. 12F shows the top view of FIG. 12C, showing the shape of needle tube floor 1260 that matches the needle gadget chamber opening 1265. FIG. 12G shows the ejector spring 1211 in a larger view with a block 1212 attached to the bottom. The block has a notch 1213 where the needle driver stays. Before acupuncture, the needle driver is at the top of the block notch 1213. When the needle gadget is inserted into the needle gadget chamber, it pushes the block 1212, compress the ejector spring 1211 and the needle driver relatively moves down the notch. When the needle gadget is fully in, the needle driver will be at the bottom of the block notch 1213. With the needle gadget inserted in defined direction, the opening on the needle tube ceiling now is right below the needle driver, allowing the needle driver to enter the needle tube and push the acupuncture needle into the human body. The locking-releasing structure for this design can adopt any locking-releasing structure presented in other places of this invention.
