The plurality of positioning pins 142 corresponding to the main body 1〇 are recessed toward the main piece 324 to form a plurality of circular grooves 327 and a plurality of circular projections 328. Each of the projections 328 has an end surface 3282. A positioning hole 3284 is formed inwardly, and the positioning hole 3284 is engaged with the cylinder 1424 on the positioning pin 142. The main piece 324 is provided with a through hole 329'. The through hole 329 is disposed so that the main piece 324 can avoid the boss 328 when the force is bent toward the holding piece 326. The first extension portion 34 includes an extension piece 342, a bent piece 344 and a reinforcing rib 346. The extension piece 342 is in the form of a rectangular sheet which extends from the main piece 324 and is at an angle to the main piece 324 toward the U-shaped connecting portion 325. The bent piece 344 has a circular arc shape, and one end thereof is connected to one end of the extending piece 342 opposite to the main piece. The reinforcing rib 346 connects the extension piece 342 and the main piece 324 for reinforcing the strength of the first extension portion 34. The first extension 34 can pass through the first through slot 16 in the body 10. The second extension portion 36 includes a substrate 362, a vertical piece 364, and a reinforcing piece 366 which is bent from both sides of the substrate 362. The substrate 362 is in the shape of a rectangular square 200803013 which extends from the main piece 324 and is at an angle to the main piece 324 toward the U-shaped connecting portion 325. The vertical piece 364 is perpendicular to the main piece 324, and the vertical piece 364 and the base piece 362 are arc-connected to one end of the main piece 324. The stiffener 366 is perpendicular to the substrate 362 and faces the vertical tab 364, which is used to reinforce the strength of the second extension 36. The second extension 36 can pass through the second through slot 18 on the body ι. The second extension 36 is flush with the top of the first extension 34. The second extension 36 has a larger volume than the first extension 34, and the corresponding second extension 36 is stronger. At the same time, referring to FIG. 11, the first extending portion 34 and the second extending portion 36 of the elastic member 30 are respectively passed through the first through groove 16 and the second through groove 18 of the body 1 while the positioning pin 142 is made. Through the through hole 329 of the main piece 324, the base 1422 of the positioning pin 142 abuts against the boss 328 of the elastic member 30, the cylinder 1424 passes through the positioning hole 3284, one end is received in the circular groove 327, and the cylinder 1424 is in the circular groove. The portion 327 is partially melted and cooled to fix the elastic member 30 to the body 10. When the battery cover 20 is installed, please refer to FIG. 12 to FIG. 15 at the same time, first place the battery in the receiving cavity 122 of the body 10, and then insert the positioning piece 25 of the battery cover 20 into the recess 125 of the body 1 to insert each. The sheet 242 is aligned with the corresponding card slot 1264 of the main body, and the first protrusion 26 of the battery cover 20 is located between the first extension portion 34 and the second extension portion 36 of the elastic member 30. Please refer to FIG. 8 10, pressing the battery cover 20 and pushing it forward, the front surface 282 of the second protrusion 28 first abuts against the substrate 362 of the second extension 36 and slides up along the substrate 362 while the main piece 324 is subjected to The force deformation is downwardly bent, and the first extension portion 34 is correspondingly sunk; continue to apply 11 200803013 Force 'When the inclined surface before the second protrusion 28 passes over the top of the second extension portion 36, the inclined surface 262 before the first protrusion 26 is also crossed The highest insertion portion 242 of the first extension portion 34 is also inserted into the card slot 1264; the force is stopped, the elastic member 30 is restored to its original shape, and the second protrusion 28 is followed by the inclined surface 284 and the vertical piece 364 of the second extension portion 36. The first protrusion 26 is followed by the inclined surface 264 and the bent piece of the first extension portion 34 The 364 is abutted against the top to prevent the battery cover 20 from moving back and forth. The rib 1263 on the protrusion 1262 stops the insertion piece 242 from moving up and down, and the positioning piece 25 is tightly engaged with the groove 125 to prevent the battery cover 20 from moving to the left or right. The battery cover 20 is fixed to the body 10. When the battery cover needs to be replaced, the battery cover 2 is removed, and the battery cover 2 is pressed and pushed back. The inclined surface 264 of the first protrusion 26 and the second protrusion 28 are followed by the inclined surface 284 along the bent piece 344 and the substrate 364, respectively. Sliding upward; the slanting surface 264 of the first protrusion 26 and the inclined surface 284 of the second protrusion 28 are respectively passed over the last point of the first extending portion 34 and the second extending portion 36 respectively. Before the inclined surface 262 and the second protrusion 28, the inclined surface 282 slides down along the extending piece 342 and the substrate 362, respectively, and the extending piece 242 is separated from the card slot 1264, and the battery cover 2 is removed, so that the battery can be replaced. It can be understood that when the battery cover 2 is mounted, since the second protrusion 28 is higher than the first protrusion 26, and the second extension 36 is flush with the first extension 34, the second protrusion 28 first abuts the second extension 36 first.
