The detection pin 36 can only move in one direction. When the button 21 is pressed, even if the button 21 is released, the hook 3 can remain in the unhooked state. The user can perform the operation of separating the external device 5 from the engaging device 1G with both hands. When the external device 5 is removed, the detection pin % is disengaged from the positioning portion 34, the blocking action disappears, and the respective components of the engaging device 1 are returned to the initial state, ready for the next engagement. Since the first contact surface 354 is not only parallel to the γ-axis direction but also faces the positive direction of the X-axis and the z-axis, the first contact surface 354 of the latching block 344 and the second contact surface 374 of the resisting block 366 are separated. The frictional resistance is small, thereby making it easier to separate the detecting pin 36 from the positioning portion 34. In summary, the first guiding groove 2 in the engaging device 1 , the second bow guiding groove 266 a , 266 b 266 c , the third guiding groove 268 and the fourth guiding groove 346 are respectively associated with the first guiding pin 412 . The second guiding bolts 416a, 41讣, the first guiding; the f-drying 282 and the first guiding rod 270 are used in combination, and the positional relationship is changed, and the 18 1364645 ILH is guided. The first link 24 and the ith take-in are introduced into the engaging device 10. The two positions are changed to match the structure of the housing 40 and the position of the hook-, and the form...21 is directly rotated with the second connection S. If the 4th/dry 26 directly abuts the hook 3G and can drive the hook 30 to the 26" portion of the housing 4G, it is not necessary to move the second link 26 correspondingly. Since the positioning portion 34 and the abutting block 366 of the detecting pin 36 are simultaneously engaged with the abutting block 366 of the detecting pin 36, at least one of the positioning portion 31 and the resisting block 366 can be produced along the γ axis. And the third spring % can be abutted against the detecting pin 36, and the block 366 is exchanged for the position, and also has a one-way resisting function. The positioning portion 34 or the detecting pin 36 can also be rotated. For example, when the detecting pin 36 and the positioning portion 34 (4) 2 are fixed on the second connecting rod %, the detecting lock 36 is forced to rotate to make the second connecting rod. 26 can = move 'When the second link 26 moves to the initial state, the detection pin % k bit portion 34 generates abutment 'also achieves a one-way abutment function. In i, the positioning portion 34 and the detecting pin 36 can still exchange positions because at least one of the two can move relative to each other. The above-described engaging device 1 can be used for a docking station of electronic products such as a pen-type computer, a portable player, and a portable game machine of various electronic devices and mechanical devices. Take the extension of the notebook computer as an example, see Figure 10. The docking station 50 includes a casing 52 and a connector 54, and the casing engaging means 1 is shared with the casing 40. The housing 4 is further provided with a limiting hole 48 corresponding to the device: and the limiting hole occupies 19 of the second through hole. 1 1364645 === bit hole 仏 connected with the notebook computer (not shown) The hook 30 of the mouth device is engaged with the notebook computer, and the electrical connection between the 54 is more stable. When the notebook type information needs to be removed, press the button 21 and release it, and the user computer is disconnected from the connector 54 on the extension 50. And: After being removed, the components of the engaging device 10 are returned to the state of the notebook type = the front of the docking station 50, which is very convenient to use.
