The second end wall portion 523 covers and is spaced from a portion of the second annular surface 324 corresponding to the protruding portion 326 . Since the stop piece 511 of the stop ring 51 and the shield 52 will not contact and interfere with the knob 3, when the user slides the operation part 316, the knob 3 can smoothly move relative to the stop. The ring 51 and the shutter 52 rotate.

4 and 5, since the stop piece 511 is spaced between the first ring surface 323 of the flange 322 and the back end 312 of the disc body 31, and the stop piece 511 is C-shaped, therefore , the blocking piece 511 will play the role of blocking the rest of the first annular surface 323 corresponding to the protruding portion 326, that is, most of the first annular surface 323 will be blocked by the Blocked by sheet 511. When the user pulls the disc body 31 along a pulling direction D1 with fingers, the first ring surface 323 will be stopped by the stop piece 511 after the flange 322 moves for a short distance, so that the knob 3 cannot continue move. By this, It can prevent the user from pulling up the knob 3 and causing it to separate from the shaft 221 and fall off.

Since the first end wall portion 522 is spaced between the portion of the back end 312 corresponding to the operating portion 316 and the portion of the first annular surface 323 corresponding to the protruding portion 326 , the first end wall portion 522 It will play a role of blocking the portion of the first ring surface 323 corresponding to the protruding portion 326 . When the user pulls the operating part 316 along the pulling direction D1 with fingers, the part of the disc body 31 close to the operating part 316 drives the protruding part 326 of the flange 322 to move up for a short distance, and the first ring The portion of the surface 323 corresponding to the protruding portion 326 will be blocked by the first end wall portion 522 , thereby quickly blocking the flange 322 so that the knob 3 cannot move. Thereby, the user can prevent the user from pulling up the knob 3 from the operating portion 316 and causing it to fall off.

On the other hand, since the blocking member 52 covers the portion of the back end 312 corresponding to the operating portion 316, when the user intends to pull the portion of the back end 312 corresponding to the operating portion 316 along the pulling direction D1 through fingers , the user's fingers will be blocked by the second end wall portion 523 of the blocking member 52 and cannot touch the portion of the back end 312 corresponding to the operating portion 316 . Thereby, the user can prevent the knob 3 from falling off by pulling up the knob 3 from the back end 312 .

By forming the avoidance groove 524 for the protruding part 326 and covering the protruding part 326 by the shielding part 52, it is possible to prevent the protruding part 326 from being exposed and affecting the function of the electronic device 100 (as shown in FIG. 1 ). Exterior. In addition, by the side wall portion 521 covering the convex The outer peripheral surface 325 of the edge 322 is corresponding to the protruding portion 326 and spaced therefrom, so that the side wall portion 521 can protect the protruding portion 326 from being compressed. When the user presses the sidewall portion 521 along a pressing direction D2 through the finger, the sidewall portion 521 will buffer and absorb the pressure exerted by the finger, so as to prevent the protruding portion 326 from being pressed and moving. Thereby, it is possible to prevent the knob 3 from moving under pressure and causing the central groove 314 to disengage from the locking blocks 222 of the shaft 221 .

It should be noted that although the electronic device 100 is described as having the button 4 as an example, in other implementations of this embodiment, the electronic device 100 may also omit the button 4 .

To sum up, in the electronic device 100 of this embodiment, the stop piece 511 of the stop ring 51 can block the first ring surface 323 of the flange 322 corresponding to the protruding portion 326, and the first end wall portion 522 of the blocking member 52 can play the role of blocking the first ring surface 323 corresponding to the protruding portion 326, which can prevent the user from placing the Knob 3 is pulled up causing it to fall off. In addition, the blocking member 52 covers the portion of the back end 312 of the tray body 31 corresponding to the operation portion 316 , preventing the user from pulling up the knob 3 from the back end 312 and causing it to fall off. Moreover, by the side wall portion 521 of the blocking member 52 covering the portion of the outer peripheral surface 325 of the flange 322 corresponding to the protruding portion 326, the side wall portion 521 can protect the protruding portion 326 to Preventing it from moving under pressure can prevent the central groove 314 of the knob 3 from breaking away from the shaft 221, so the purpose of the present invention can be achieved.
