The limiting plate 331 of the braking member 33 is disposed between the first-staged portion 316 and the second blocking portion 317 of the housing 311, and the rod portion 333 is configured to be sleeved and latched by the second reset The groove 叩 of the second stopping portion 317 is such that the first spring 36 abuts between the limiting plate 331 and the second stopping portion 317, so that the braking member 33 resets the elastic force, so that the limiting plate 331 is blamed. Pressing the first 316, the first and second latching portions 334 335 can be positioned at the position of the first limiting portion 326 and the first card slot 329, or the clamping position is respectively The second limit portion 327 and the second card slot 330 are located at the position 12 M357833. As shown in FIG. 2 and FIG. 2, the hook 32 phase 311 is in the housing of the driver button 31. Exposing the first position of the first face 21 (as shown in FIG. 2), and the first through hole 219 of the face of the (4) μ through hole 218 face 2U, the fishing portion 324 is exposed to the second "fishing 32"; When the position between the rotation and the eclipse is as shown in FIG. 8 , the first and second latching portions 334 15 of the brake member 33 are respectively engaged by the elastic force of the second return spring 35 = 2332: the first limiting portion 326 and In the first - card slot 329, so the picture: two exposed The first position of the first through hole 218. As shown below, the electronic device 100 is in the use mode of the notebook computer. When the screen 2 is covered with the main body 1, the first side of the flute 21 is shown along the arrow 1. 211 is rotated toward the top surface of the first casing 11, and 323 is positioned at the first position. Therefore, during the process of covering the top surface of the second casing 21, the first fishing portion 323 touches the edge of the card hole 4 to drive the sole 31 moves to the right and compresses the first reset on the right side. After the first hook portion 323 is separated from the hole edge position of the card hole 111, the button 31 and the first fishing portion Γ3/reset are reset by the reset elastic force of the right side 1 spring 34. The first hook portion 323 can be slid in the card hole m so that the second casing 21 and the first casing u are locked. In addition, when the display screen 2 is to be turned on, the pushing portion 314 of the button 31 is pressed. Moving to the right to drive the first fishing part to cut off and the card position of the Kakonchuan f. The first casing 21 and the first casing 21 are released from each other, so that the second casing 2! Rotate in the direction of the arrow! relative to the first unit to open the display screen 2. 13 M357833 To make the electronic device 100 from the notebook computer shown in Fig. 1. When the mode is switched to the tablet mode shown in FIG. 11, the user can operate as follows: As shown in FIG. 6 and FIG. 8, the first hook portion 323 of the hook 32 is manually indicated by the arrow 11 The direction is rotated relative to the housing 311. When the curved surface 328 of the projection 322 touches the first latch portion 334 of the brake member 33, the projection 322 biases the brake member 33 to the right to cause the brake member 33 to be While shifting to the right, the limiting plate 331 of the brake member 33 compresses the second returning magazine 35, and when the hook 32 is rotated by about 9 degrees, the second hook portion 324 is rotated to the second position where the second through hole 219 is exposed. The second limiting portion and the second locking slot 330 of the hook 32 respectively correspond to the positions of the first latching portion and the second latching portion 335 of the braking member 33, by the reset elastic force of the second reset magazine 35 The brake member 33 is reset and the first and second latching portions 334' 335 are respectively latched to the second limit slot 327 and the second latching slot 33, whereby the second fishing portion can be positioned at the second position. As shown in FIG. 9, FIG. 1 and FIG. u, next, the second casing 21 is rotated by about 180 degrees with respect to the first casing 11 in the direction indicated by the arrow hi or opposite to the direction of the arrow m, and then along the arrow I. The direction shown rotates the second face 212 of the second casing 21 toward the top surface of the first casing u. Since the second hook 324 is positioned at the second position, the second casing 21 covers the first casing 11 During the process of the top surface, when the second hook portion 324 touches the hole of the hole of the card hole, the button 31 is moved to the right and the first return spring 34 of the right side is compressed, and the second hook portion 324 is separated from the edge of the hole of the card hole m. After that, the button 31 and the second hook portion 324 are pressed to reset the two hook portions 324 by the reset elastic force of the right L-th spring 34, so as to be stuck in the card hole (1), so that the second casing 21 and the 14th M357833 casing 11 are In the lock plate mode. When the electronic device 1 is switched to be flat, the display screen 2 is moved back to the right to drive the m 4th, and the push portion 314 of the single 31 can be detached from the click position of the card hole 111.

The spin dryer is further rotated 21 in the direction opposite to the arrow I relative to the first housing to open the display screen 2. Tian Ran's operation sequence can also be in the direction indicated by arrow III or opposite to the arrow.

The direction rotates the first casing 21 relative to the first casing 11 by about 180 degrees 1 and then rotates the first fishing portion 323 of the catch 32 relative to the casing 3U in the direction indicated by the arrow I]t (as shown in FIG. 8). The second fishing portion 324 $ is exposed to expose the first through hole 219, and then the second casing and the first surface 212 are oriented toward the first casing in the direction indicated by the arrow I. 11 The top surface is rotated, and the second fishing boat 324 can be clamped to the card hole 111, which is not limited to the operation sequence disclosed in this embodiment. It should be noted that, in actual design, the hook 32 can omit the first and first slots 329, 330, and the brake member 33 can omit the second latch portion 335, and the phase 32 can also be positioned at the first - The position and the second position are effective, but the first and second latching portions 334 and 335 of the brake member 33 disclosed in the embodiment can be respectively engaged with the first limiting portion 326 of the hook 32 and the first The design of the second slot 327 and the second slot 330 of the latch 329' or the hooks 32 respectively provides a better and more stable latching strength. In summary, the electronic device 100 of the present embodiment can securely position the hook 32 in the first position or the second position by the design of the braking member 33 of the locking mechanism 3, so that the first hook portion 323 of the hook 32 is 323. Or the second hook portion 324 15 M357833: when the first hole 323 or the first fishing portion 324 is stuck in the card hole 111 of the first casing U, it can increase the purpose of the new type. , _ card _ degrees, can really reach this
