Figures 8, 8a and 8b show that the movable part 18 includes a first and second connecting portion 34, 36. When the movable member 18 is folded relative to the fixed member 16, the first and second connecting portions 34, 36 respectively correspond to the return mechanism 40 and the ejecting mechanism 120. The connection relationship between the returning mechanism 40 and the first connecting portion 34 is defined by a common relationship between the second lateral portion 116 of the locking member 50 and the first wall 100 of the third portion 88 of the inclined member 44. The locking space 118 is configured to provide a first connection of the movable component 18 to the card. The connecting relationship between the ejecting mechanism 120 and the second connecting portion 36 is the second connecting portion 36 of the movable member 18 by the pushing member 124, and is connected to the fixing base 122 by the second elastic member 126.

Figures 10a and 10b are schematic views showing that the return mechanism 40 acts on the movable member 18 to cause the movable member 18 to self-close and retract relative to the fixed member 16. In this state, the first connecting portion 34 is located in the locking space 118 defined by the locking member 50 and the tilting member 44 for providing the first connecting portion 34 to be abutted. Therefore, when the lock member 50 is pulled back by the first elastic member 48 by the tilting member 44, the first connecting portion 34 is pulled by the lock member 50, so that the movable member 18 can be the first elastic member. The elastic force of the first direction F1 of the 48 is pulled and displaced relative to the fixing member 16. At the same time, the second connecting portion 36 is displaced rearwardly and the pushing member 124 that drives the ejecting mechanism 120 is also displaced backward. The elastic force of the second elastic member 126 is smaller than the elastic force of the first elastic member 48. Therefore, the pushing member 124 can be moved back by the second connecting portion 36, and the second elastic member 126 is in an initial state. The elastic force stored in the second direction F2 acts on the pusher 124. In addition, the adjusting member 144 is positioned against the blocking member 132.

11a, 11b, and 12 are diagrams showing the action of pressing the external force of the first direction F1 toward the movable member 18, and the adjusting member 144 of the adjusting mechanism 140 pushes the blocking member 132 of the positioning mechanism 130. The member 132 then compresses the third resilient member 134 for longitudinal displacement relative to the guide member 42. At the same time, the first connecting portion 34 of the movable member 18 pushes the first wall 100 of the inclined member 44 to move backward, so that the locking member 50 is also moved back along with the inclined member 44, and the first lateral portion of the locking member 50 is moved forward. The guide member 78 is further abutted along the guiding surface 78 of the stopping portion 76 of the guiding member 42 to cause a downward displacement of the locking member 50 to be pressed and disposed on the locking member 50 and the inclined member 44. The elastic piece 52 (please refer to FIG. 2), the lock member 50 then releases the abutting relationship with the first connecting portion 34 of the movable member 18, and the locking space 118 forms an open space. The tilting member 44 is pulled by the elastic force of the first elastic member 48 and moved backward by a distance and stopped relative to the guiding member 42. Moreover, at the same time, the pushing member 124 of the ejecting mechanism 120 is also pushed and displaced by the second connecting portion 36 of the movable member 18, and the pushing member 124 stretches the second elastic member 126 during the displacement process, so that the first The elastic force of the two elastic members 126 acting on the pusher 124 is greater than the elastic force in the initial state. Therefore, after the external force in the first direction F1 is pressed toward the movable member 18, the first connecting portion 34 of the movable member 18 is untwisted from the lock space 118, and after the external force in the first direction F1 is released The second connecting portion 36 of the movable member 18 is pushed out by the pushing member 124 by the force of the second elastic member 126 acting in the second direction F2 of the pushing member 124. 18 can be ejected self-opening relative to the fixing member 16.

Figures 13a and 13b show the position at which the movable member 18 is ejected relative to the fixed member 16 to be self-opening. During this process, the second connecting portion 36 of the movable member 18 is pushed out by the ejecting mechanism 120 by the elastic force of the second elastic member 126 being released by the pushing member 124. According to the elastic force released by the second elastic member 126, the second connecting portion 36 of the movable member 18 can be displaced to be opened relative to the fixing member 16. Preferably, the displacement position of the second connecting portion 36 is abutting against the abutting portion 104 of the inclined member 44 to stop the displacement, so that the movable member 18 is kept open relative to the fixing member 16 by a predetermined distance.

Figure 14 is a view showing the second connecting portion of the movable member 18 when the movable member 18 is pulled away from the fixed member 16 by a larger distance after the movable member 18 is opened relative to the fixed member 16. The displacement is brought about by the abutment 36, and the tilting member 44 can be slidably displaced along the first and third longitudinal portions 60, 64 of the guide member 42 by the first and third sliding portions 92, 96.

15 is a view showing that after the movable member 18 is continuously pulled out relative to the fixing member 16, the first and third sliding portions 92, 96 of the inclined member 44 are driven along the first and third longitudinal portions of the guiding member 42. 60, 64 slidingly displaced, when the first sliding portion 92 of the tilting member 44 slides to the end of the first longitudinal portion 60 of the guiding member 42, it will slide further into the lateral portion connected to the end of the first longitudinal portion 60. 68, the inclined member 44 is inclined at an angle with respect to the guiding member 42 and is detached from the second connecting portion 36 of the movable member 18, and the elasticity generated by the first elastic member 48 is obtained. The force acts on the tilting member 44 to maintain the tilting member 44 in a state of being inclined and positioned relative to the guiding member 42, so that the movable member 18 can be freely pulled out relative to the fixing member 16.

After the movable member 18 is opened relative to the fixed member 16, the first sliding portion 92 of the inclined member 44 stays at the lateral portion 68 of the guide member 42 in a normal state. If the first sliding portion 92 of the inclined member 44 is disengaged from the lateral portion 68 of the guiding member 42 due to an abnormal situation or is detached before reaching the front portion, and is slid into the first longitudinal portion 60 of the guiding member 42, at this time, As shown in FIG. 16, the inclined member 44 is pulled back by the elastic force of the first elastic member 48, and the third sliding portion 96 of the inclined member 44 is slid to the third longitudinal portion 64 of the guiding member 42. The end position is stopped and a state of failure is formed.

Figure 17 is a view showing that the above-mentioned failure state is released, and the movable member 18 can be pushed into and folded with respect to the fixed member 16, and the second connecting portion 36 of the movable member 18 first abuts against the abutting portion of the inclined member 44. The inclined back surface of 104, and by the pushing action of the movable member 18 relative to the fixing member 16, the second connecting portion 36 can be pressed along the abutting portion 104 of the inclined member 44 and over the inclined member The abutting portion 104 of the 44, at this time, the movable member 18 is further pulled out relative to the fixing member 16, and the tilting member 44 is again displaced along the first longitudinal portion 60 of the guiding member 42 to make the The first sliding portion 92 of the tilting member 44 can be slid into the lateral portion 68 by the first longitudinal portion 60 of the guiding member 42 and the inclined member 44 is inclined against the guiding member 42 (please See Figures 14 and 15). Alternatively, referring to FIG. 24, when the movable member 18 is pushed into and folded relative to the fixing member 16, the second connecting portion 36 of the movable member 18 first abuts against the inclined surface 111 of the abutting member 107. And further pushing the movable member 18 relative to the fixing member 16, so that the second connecting portion 36 can press the fourth elastic member 105 along the inclined surface 111 of the abutting member 107, and over the The abutting member 107, the elastic force of the pressed portion of the fourth elastic member 105 is then restored to push the abutting member 107. At this time, the movable member 18 can be pulled out again relative to the fixing member 16, and the elastic member 18 can be restored. The tilting member 44 is driven.

18 and 19 are diagrams showing the first connecting portion 34 abutting against the first wall 100 of the tilting member 44 when the movable member 18 is pushed into a predetermined position after being opened relative to the fixing member 16. And by the retracting action of the movable component 18, the tilting displacement of the tilting member 44 can be driven to cause the first sliding portion 92 of the tilting member 44 to leave the lateral portion 68 of the guiding member 42 and return to The first longitudinal portion 60 of the guiding member 42 is positioned. At this time, the second lateral portion 116 of the locking member 50 and the first wall 100 of the inclined member 44 define a locking space 118, and then the first connecting portion 34 is abutted, and the tilting member 44 is pulled backward by the elastic force of the first elastic member 48, and the first connecting portion 34 of the movable member 18 is also abutted by the locking member 50 to be displaced. The movable member 18 can be self-closing relative to the fixed member 16.
