[0036] Through the technical personnel in the art, the parts in the case are connected in sequence, and the specific connection and operation sequence should be referred to the working principle described below. The detailed connection means is a well-known technology in the art, and the working principle and process are mainly introduced below.
[0037] When the device needs to be used, the perforated solid needle 5 can be inserted into the circular groove of the handle 1 first, and the perforated solid needle 5 is connected with the handle 1, then the push tube 2 and the guide tube 8 are sequentially sleeved on the perforated solid needle 5, and the lower part of the push tube 2 is inserted into the annular groove of the handle 1. When the user needs to wear the ornament on the ear, the operator can pinch the anti-skid texture 4 on the handle 1 with one hand, and hold the contact tube 9 against the user's ear hole with the other hand. If the user's ear hole is in a special position of the ear, the 45° inclined angle face part 6 of the contact tube 9 can be in contact with the ear. Then the operator can move the push tube 2, the perforated solid needle 5 and the guide tube 8 through the handle 1, so that the perforated solid needle 5 penetrates into the user's ear hole through the solid three-angled needle head 7. At this time, the operator can push the circular ring-shaped push table 3 through the thumb, so that the circular ring-shaped push table 3 drives the push tube 2 to move, so that the push tube 2 pushes the guide tube 8 on the perforated solid needle 5, so that the guide tube 8 also smoothly penetrates through the user's ear hole. Since the diameter size of the guide tube 8 is larger than that of the perforated solid needle 5, when the perforated solid needle 5 leaves the user's ear hole, the guide tube 8 can remain in the user's ear hole. Since the guide tube 8, the push tube 2 and the handle 1 are designed as a split body, it is not necessary to cut the guide tube 2, so the operation is more convenient. At the same time, since the diameter size of the guide tube needle is smaller than that of the perforated needle on the market, it is more convenient to penetrate into the work. The perforated solid needle 5 is solid, and the solid three-angled needle head 7 is designed as a three-angled shape. Compared with the hollow perforated needle on the market, the hardness is higher, and it is more solid, and is not easy to deform, break and other problems during use. The perforated solid needle 5 is also coated with a layer of silicone oil 10, so that the surface of the perforated solid needle 5 is smoother, and it is easier to penetrate into the ear hole of the person, and the sharpness of the perforated solid needle is further improved, so that the pain and swelling of the user can be effectively reduced, and the use effect is better.
[0038] When the guide tube 8 is penetrated into the user's ear hole, the titanium alloy ornament base can be threadedly connected with the contact rod first, and then the contact rod is inserted into the guide tube 8 together with the titanium alloy ornament base until the titanium alloy ornament base is in close contact with the user's ear. Then the guide tube 8 is taken off from the contact rod, and the contact rod is taken off from the titanium alloy ornament base. At this time, only the titanium alloy ornament base exists in the user's ear hole. Finally, the titanium alloy ornament is connected with the titanium alloy ornament base, and the wearing is completed.
