Referring to fig. 2 and 5 together, fig. 5 illustrates the structure of the hook 206. The hook 206 is Z-shaped, and includes a vertical portion, and a hook portion 2062 and a protruding portion 2061 connected to the vertical portion, and the hook portion 2062 and the protruding portion 2061 are respectively located at two opposite sides of the vertical portion. The protruding portion 2061 is perpendicular to the vertical portion, and the hook portion 2062 has an inclined feature 2063. The perpendicular of the protrusion 2061 to the vertical portion is only a specific example, and the protrusion 2061 may be at an angle smaller than or larger than 90 ° with respect to the vertical portion, and is not limited to the perpendicular. With continued reference to fig. 2 and 5, a shaft hole 2064 is disposed at a position of the vertical portion near the protruding portion 2061, and with reference to fig. 2, the fixing member 201 is provided with a rotating shaft 207, the shaft hole 2064 is sleeved on the rotating shaft 207, and the hook 206 can rotate clockwise (in a direction shown by a solid line in fig. 2) and counterclockwise (in a direction shown by a broken line in fig. 2) as shown in fig. 2. A step structure 2051 is disposed at the edge of the module 205, and the step structure 2051 has a second engaging groove engaged with the engaging hook portion 2062. The stepped structure 2051 is only a specific example for implementing the second card slot, and the form of the second card slot is not limited in this example, and only the second card slot that can be fastened and fixed with the hook 206 is provided on the module 205. With reference to fig. 2, in order to drive the hook 206 to rotate to realize self-locking, a torsion spring 211 is disposed on the hook 206, the torsion spring 211 is sleeved on the rotation shaft 207, one end of the torsion spring 211 abuts against the hook 206, and the other end abuts against the fixing member 201. The pre-tightening force of the torsion spring 211 enables the hook 206 to rotate counterclockwise to a certain angle around the pin 207 when no external force is applied. When the fixing member 201 rotates counterclockwise to a certain angle around the rotation shaft 207209, the inclined surface feature 2063 of the hook 206 contacts with the left side surface of the stepped structure 2051, and the inclined surface feature 2063 drives the hook 206 to rotate clockwise to a certain angle around the pin shaft 207, so that the hook can cross the barrier of the upper surface of the stepped structure 2051; the fixing member 201 continues to rotate counterclockwise around the rotating shaft 209, when the fixing member rotates to the first slot 2013 to engage with the second slot and lock the module 205 on the device, the protruding feature 2011 on the fixing member 201 and the upper surface of the stepped structure 2051 on the module 205 are abutted to each other for limitation, the fixing member 201 cannot continue to rotate clockwise, the torsion spring 211 pushes the hook 206 to rotate counterclockwise around the pin 207 to a certain angle, the hook portion 2062 of the hook 206 contacts with the lower surface of the stepped structure 2051, the hook 206 engages with the second slot and locks the fixing member 201 at a set position, and a state that the fixing member 201 is locked on the module 205 as shown in fig. 2 is formed.

As can be seen from fig. 2, when the module 205 is inserted into the device, the spring provided by the module enables the hook 206 to rotate counterclockwise to a specific angle around the pin 207 when not subjected to an external force, that is, the hook portion 2062 of the hook 206 is hooked on the lower surface of the step structure 2051 on the module 205, and the fixing member 201 cannot rotate counterclockwise because the protruding feature 2011 of the fixing member 201 and the upper surface of the step 2051 on the module 205 are abutted against each other for limiting; in summary, a reliable self-locking of the fixing member 201 is achieved, i.e. the fixing member 201 cannot rotate around the pin 209 in any direction.

It should be understood that, in the embodiment of the present application, the structure for driving the hook 206 to rotate is not limited to the torsion spring 211, but may also be a spring (a tension spring or a compression spring) or another elastic member, and only needs to be able to drive the hook 206 to cooperate with the second slot.

Referring to fig. 2 and 6 together, fig. 6 illustrates the structure of the unlocking lever 204 in the handle 202 assembly, and the unlocking lever 204 is used for driving the hook 206 to unlock the second card slot. The unlocking lever 204 shown in fig. 6 is a lever structure. The unlocking lever 204 includes a pressing end 2043 and an unlocking end 2041 for cooperating with the hook 206, a shaft hole 2042 is provided between the unlocking end 2041 and the pressing end 2043, and the unlocking end 2041 is an arc-shaped bending structure. The unlocking is convenient. As shown in fig. 2, the handle 202 is provided with an avoiding groove (not shown) engaged with the unlocking lever 204, and the unlocking lever 204 is located in the avoiding groove and rotatably connected to the handle 202. During assembly, the shaft hole 2042 of the unlocking lever 204 is assembled on the pin 208 arranged in the avoiding groove, and the bent unlocking end 2041 of the unlocking lever 204 points to the insertion end 2022 of the handle 202; a gap for accommodating the protruding portion of the hook 206 is formed between the unlocking end 2041 and the handle 202, and a space for avoiding the rotated hook 206 is provided in the avoiding groove (refer to the effect of the rotated hook 206 shown in fig. 7). Referring to fig. 2 and 6 together, the unlocking lever 204 is provided with a torsion spring 213, and the pretightening force of the torsion spring 213 enables the unlocking lever 204 to rotate clockwise to a certain angle around the shaft hole 2042 of the pin 208 when the unlocking lever 204 is not subjected to an external force, abuts against the side wall of the avoiding groove, and limits the rotation angle of the unlocking lever 204 through the side wall of the avoiding groove. It should be understood that, in the embodiment of the present application, the first elastic member for pushing the unlocking lever 204 against the avoiding groove is not limited to the torsion spring 213 shown in fig. 6, and a spring (a tension spring or a compression spring), an elastic rubber or other elastic member may be used.

As shown in fig. 7, when the module 205 needs to be pulled out, the handle 202 assembly is inserted into the connecting assembly, the protruding portion of the hook 206 is inserted into the gap between the unlocking end 2041 and the handle 202, the pressing end of the unlocking lever 204 is pressed, the unlocking end 2041 of the unlocking lever 204 contacts with the protruding portion 2061 of the hook 206, the unlocking lever 204 drives the hook 206 to rotate clockwise around the pin 207, the hook portion 2062 of the hook 206 is separated from the lower surface of the stepped structure 2051, and the hook 206, i.e., the connecting portion, is located to complete quick unlocking. After unlocking the fixture 201, the handle 202 and fixture 201 may be rotated together clockwise about the pin 209, pulling the module 205 upward, as shown in fig. 8.

As can be seen from the above description, in the extraction aid provided in the embodiment of the present application, the self-locking button 210 and the hook 206 are respectively arranged on two sides of the slot 2012, and the rotation direction of the unlocking lever 204 when the hook 206 and the second slot are driven to unlock is opposite to the rotation direction when the extraction aid unlocking module 205 is driven, so as to avoid the reliability of each component in the extraction aid during the unlocking process. Illustratively, the unlocking direction of the self-locking button 210 is counterclockwise, the locking rotation direction of the extraction aid unlocking module 205 is clockwise, and the rotation directions of the self-locking button 210 and the handle 202 are opposite, so that when a force is applied to the handle 202, the locking force between the self-locking button 210 and the handle 202 is increased, and the self-locking button 210 is prevented from being disabled during unlocking. The unlocking lever 204 rotates clockwise when the hook 206 is driven, and the pressing end 2043 of the handle 202 is located on one side of the holding part (the end far away from the insertion end 2022) on the handle 202, so that the operator can conveniently press the pressing end 2043 with fingers when holding the holding part, and the operation of the operator is facilitated.
