The second connection structure 142 is disposed outside the second accommodating portion 141, and the second outer portion 143 is located outside the second connection structure 142. The second connection structure 142 is connected to the first connection structure 112, and the second outer portion 143 and the first outer portion 113 are located on both sides of the metal ring 13. Further, the extension portion 130 of the metal ring 13 is also located outside the second outer portion 143 and the first outer portion 113. In other words, the perforation 132 is also located outside the second outer portion 143 and the first outer portion 113.

[0036] Please refer to Figure 6 and Figure 7 , Figure 6 is Figure 4 a cross-sectional view taken along line A-A' of Figure 7 and Figure 4 is an enlarged view of area B of Figure 7 . In this embodiment, the first outer portion 113 of the first housing 11 further includes a plurality of fixing blocks 1131, and the plurality of fixing blocks 1131 are evenly and dispersedly disposed on the first outer portion 113 of the first housing 11. The metal ring 13 is an integrally formed structure made of a metal material, and it is formed by metal blanking and rolling using a general metal material to ensure that the metal ring 13 can achieve sufficient tensile strength. The inner side of the metal ring 13 has a plurality of fixing notches 131, and the plurality of fixing notches 131 are fitted and fixed corresponding to the plurality of fixing blocks 1131. Among them, the top end of the fixing block 1131 has a fixing convex portion 11311 extending outward relative to the side of the fixing notch 131, and the outer diameter of the fixing convex portion 11311 is slightly larger than the diameter of the fixing notch 131. In this way, when the plurality of fixing blocks 1131 are fitted into the plurality of fixing notches 131, the fixing convex portions 11311 of the plurality of fixing blocks 1131 are squeezed and fixed in the plurality of fixing notches 131, so that the fixing convex portions 11311 and the fixing notches 131 are interferentially fixed (

[0037] Furthermore, the first outer portion 113 of the first housing 11 further includes a plurality of fixing grooves 1132. The plurality of fixing grooves 1132 are grooves extending along the outer contour of the first outer portion 113, and the plurality of fixing grooves 1132 are located between the plurality of fixing blocks 1131. The plurality of fixing grooves 1132 are used to fill adhesives, double-sided tapes, or any adhesive products for fixing, etc. The above products need to be compatible adhesives that can adhere to both the metal material (i.e., the metal ring 13) and the plastic material (i.e., the first housing 11). When the metal ring 13 is disposed on the first outer portion 113 of the first housing 11, the metal ring 13 is adhered and fixed to the fixing grooves 1132, thus strengthening the connection strength between the metal ring 13 and the first outer portion 113 of the first housing 11.

[0038] Moreover, the first accommodating portion 111 of the first housing 11 has a first accommodating groove 1111 and a plurality of fixing columns 1112. The plurality of fixing columns 1112 are disposed at the bottom of the first accommodating groove 1111. The electronic component 12 has a circuit board body 121, and the circuit board body 121 has a plurality of fixing holes 1211. The circuit board body 121 is disposed in the first accommodating groove 1111, and the plurality of fixing columns 1112 pass through the plurality of fixing holes 1211 of the circuit board body 121. Among them, the top of the fixing column 1112 is heated to thermally fuse and fix the top of the fixing column 1112 to the circuit board body 121, so that the electronic component 12 is fixed in the first accommodating groove 1111.

[0039] In addition, the first accommodating portion 111 of the first housing 11 further has a positioning wall 1113. The positioning wall 1113 is disposed at the bottom of the first accommodating groove 1111. The circuit board body 121 has a fixing notch 1212. The circuit board body 121 is disposed in the first accommodating groove 1111. The positioning wall 1113 is located outside the circuit board body 121, and the positioning wall 1113 is located in the fixing notch 1212 of the circuit board body 121. Thus, the positioning wall 1113 can position the position and direction of the circuit board body 121 of the electronic component 12.

[0040] In this embodiment, the first connection structure 112 of the first housing 11 includes a fixing groove 1121, and the second connection structure 142 of the second housing 14 includes a fixing convex ring 1421.

Furthermore, the second connection structure 142 of the second housing 14 further includes a fixing sleeve 1422, and the fixing sleeve 1422 is made of waterproof silicone. The inner surface and the outer surface of the fixing convex ring 1421 both have a serrated structure 14211. The fixing sleeve 1422 completely covers the surface of the fixing convex ring 1421, so that the fixing sleeve 1422 also covers the serrated structure 14211. Thus, the fixing sleeve 1422 has a high connection strength with the fixing convex ring 1421. At the same time, the outer surface of the fixing sleeve 1422 will also present a serrated shape.

[0041] At this time, when the fixing convex ring 1421 is fitted into the fixing groove 1121, the fixing sleeve 1422 is pressed into the fixing groove 1121, that is, the fixing sleeve 1422 is fixed between the fixing convex ring 1421 and the fixing groove 1121. After the serrated surface of the fixing sleeve 1422 interferes and enters the fixing groove 1121, the serrated surface of the fixing sleeve 1422 is gradually deformed and closely adheres to the inside of the fixing groove 1121. In other words, the serrated inner surface of the fixing sleeve 1422 closely adheres to the inner groove wall inside the fixing groove 1121, while the serrated outer surface of the fixing sleeve 1422 closely adheres to the outer groove wall inside the fixing groove 1121. The fixing sleeve 1422 on the fixing convex ring 1421 is fitted and fixed in the fixing groove 1121( Figure 7 The overlapping part of the fixing sleeve 1422 and the fixing groove 1121 in ) is shown as the area of mutual interference and extrusion), so as to improve the waterproof effect of the anti-loss device 1. At the same time, the friction between the fixing sleeve 1422 and the fixing groove 1121 can also strengthen the assembly connection strength between the first housing 11 and the second housing 14.

[0042] Please refer back to Figure 3 , in this embodiment, the first connection structure 112 of the first housing 11 includes a snap groove 1122, and the snap groove 1122 is located on the groove wall of the first accommodating groove 1111. The second connection structure 142 of the second housing 14 includes a snap member 1423, and the snap member 1423 is arranged at the bottom of the second accommodating groove 1411. After the snap member 1423 of the second housing 14 enters the snap groove 1122 of the first housing 11 correspondingly, the second housing 14 is rotated relative to the first housing 11, so that the snap member 1423 of the second housing 14 is rotationally snapped into the snap groove 1122 of the first housing 11. In this way, the second housing 14 and the first housing 11 are fixed to each other. In addition, the metal ring member 13 further includes a perforation 132. The second outer portion 143 of the second housing 14 and the first outer portion 113 of the first housing 11 are located on both sides of the metal ring member 13, and the perforation 132 is located outside the first outer portion 113 and the second outer portion 143. The perforation 132 can be provided with a binding rope or a decorative line according to the needs of the user, etc.

[0043] As described above, the snap groove 1122 is a structure located on the groove wall of the first accommodation groove 1111. On both sides of the notch of the snap groove 1122, there are a first groove wall 11221 and a second groove wall 11222, and the groove direction of the snap groove 1122 extends along one side. The snap member 1423 includes a first wall body 14231 and a second wall body 14232. The first wall body 14231 extends outward from the bottom of the second accommodation groove 1411, and the second wall body 14232 extends outward from the top end of the first wall body 14231. The first wall body 14231 and the second wall body 14232 form an L-shaped structure. The snap member 1423 further includes a third wall body 14233, and the third wall body 14233 closes an opening on one side of the first wall body 14231 and the second wall body 14232, and the third wall body 14233 strengthens the structural strength of the L-shaped structure of the first wall body 14231 and the second wall body 14232.

[0044] After the second wall body 14232 of the snap member 1423 enters the snap groove 1122, the snap member 1423 rotates along the groove direction of the snap groove 1122, that is, the snap member 1423 moves toward the side with the second groove wall 11222, so that the second wall body 14232 of the snap member 1423 is fitted into the snap groove 1122, and the second groove wall 11222 of the snap groove 1122 is also fixed in the L-shaped structure of the snap member 1423, and the second groove wall 11222 presses against the third wall body 14233 of the snap member 1423.

[0045] Please refer back to Figure 3 , the first groove wall 11221 has a guiding side edge 11223. When the snap member 1423 enters the snap groove 1122, the outer side of the second wall body 14232 of the snap member 1423 is fitted into the snap groove 1122 along the guiding side edge 11223. Also, the inner side of the second groove wall 11222 presses against the second wall body 14232 of the snap member 1423, and the inner side of the second groove wall 11222 has a fixing side edge 11224, and the fixing side edge 11224 can increase in thickness from the outside to the inside of the snap groove 1122. When the inner side of the second wall body 14232 of the snap member 1423 moves into the snap groove 1122 along the fixing side edge 11224, the inner side of the second wall body 14232 of the snap member 1423 will be gradually pressed tightly by the fixing side edge 11224, so as to strengthen the tight fixing between the second housing 14 and the first housing 11.

[0046] Please refer back to Figure 2, the second accommodating portion 141 of the second housing 14 further has a pressing member 1412. The pressing member 1412 is disposed at the bottom of the second accommodating groove 1411 and correspondingly presses against the electronic component 12. In this way, the pressing member 1412 presses and fixes the electronic component 12 in the first accommodating groove 1111. Furthermore, the outer surfaces of the first housing 11 and the second housing 14 are coated with a secondary-formed soft rubber surface layer, which helps with functions such as anti-collision, waterproofing, and dustproofing.

[0047] In summary, the present application provides an anti-loss device. A metal ring is disposed between the first housing and the second housing.
