Returning to FIG. 2B, an elastic body 24 is further disposed in the recess 2110. As shown in FIG. 5, the figure is a schematic view of the elastic body being placed in the groove. In the embodiment of FIG. 5, the structure of the second positioning portion 23 of FIG. 4A and the elastic body 24 are mainly combined, wherein the card plate 231 is embedded in one end of the elastic body 24 (spring) by the card board. The arrangement of 231 can provide for securing the elastomer 24 within the recess, wherein the elastomer 24 can be, for example, a coil spring. It should be noted that, if it is in the state of FIG. 4B, one end of the elastic body 24 abuts against the side of the positioning plate 230. In addition, the card 231 does not have to be formed on the bottom surface of the recess 2110. For example, it may be formed on both sides of the recess 2110 to be embedded in the elastic body 24.

As shown in FIG. 3 and FIG. 6, FIG. 6 is a schematic cross-sectional view of the combination of the locking mechanism of the present invention. When it is to be combined, the third surface 2100 of the locking portion 21 corresponds to the first surface 200 of the fixing base 20, and is moved by the opening of the recess 202 in the direction of the protruding seat 220. When the third surface 2100 of the locking portion 21 contacts the second surface 200 of the fixing base 20, the sliding is continued to be pushed in the direction of the protruding seat 220. At this time, the two guide rails 203 on the fixing base 20 And the 204 will gradually slide into the sliding slot 2111 on both sides of the sliding seat 211. After the locking portion 21 slides inwardly for a certain distance, the gears 2112 on both sides of the sliding seat 211 of the locking portion 21 are respectively contacted. a corresponding stop block 205 on both sides of the fixed seat 20, at this time, since the gear body 2112 has a second guiding surface 2114, and has a first guiding surface 2051 on the blocking block 205, the second guiding surface 2114 and the second guiding surface 2114 A guiding surface 2051 abuts, and since the second guiding surface 2114 and the first guiding surface 2051 are inclined surfaces, respectively, when the locking portion 21 moves toward the protruding portion 220, the locking portion 21 is The two guiding surfaces 2114 can be smoothly pushed forward by the guiding of the first guiding surface 2051 without interference, so that the locking portion 21 can be smoothly slid on the fixing base 20.

In FIG. 6, when the locking portion 21 is slidably attached to the fixing base 20, since the elastic body 24 has an elastic force, the locking portion 21 can be maintained in the first position as shown in FIG. In the first position state of FIG. 6, the positioning plate 230 is received in the positioning groove 222 which is the outermost side of the cantilever 221 . At this time, the positioning groove 222 corresponding to the positioning plate 230 can provide the positioning effect, and the position of the locking portion 21 can be changed without unnecessary external force. When the locking portion 21 is in the first position state of FIG. 6, the cassette 212 can provide the effect of locking, otherwise, as shown in FIG. 7, when an external force acts, for example, pushing the locking portion 21 with the finger 90 At the time of the plate 210, the restraint of the groove 222 and the elastic force of the elastic body 24 are overcome by the action of the external force, so that the touch panel 210 moves in the direction 91. While moving, the elastic body 24 is compressed to accumulate elastic restoring force. When the locking portion 21 is in the second position state of FIG. 7, the positioning plate 230 corresponds to the positioning groove 223. At this time, since the cassette 212 is also moved in the direction 91, the effect of the locking is released. When the external force is released, the elastic restoring force accumulated by the elastic body 24 overcomes the restraint of the positioning groove 223, and the locking portion 21 is pushed to move in the direction 92, thereby returning to the state shown in FIG.

As shown in FIG. 8, the figure is a schematic diagram of an electronic device of the present invention.
