After the locking between the fixing lever 5 and the fixing hole is released, the fixing lever 5 can be ejected out of the fixing hole 40 based on the elasticity of the elastic member 6 to realize the separation between the fixing lever 5 and the positioning column 4. Here, the expansion card holder 100 is in an unlocked state in fig. 5(a), and the expansion card holder 100 is in an unlocked state in fig. 5 (B).
In another case, as shown in fig. 6, the elastic member 6 is stretched during the fixing rod 5 goes deep into the fixing hole 40 and is maintained in a stretched state while the fixing rod 5 is locked. After unlocking, the fixing lever 5 may also be drawn out of the fixing hole 40 based on the elastic force generated by the elastic member 6 stretching.
Here, the expansion card holder 100 is in an unlocked state in fig. 6(a), and the expansion card holder 100 is in an unlocked state in fig. 6 (B).
Through setting up elastic component 6, can make after the locking between dead lever 5 and reference column 4 is relieved, realize breaking away from between dead lever 5 and the reference column 4 fast reliably, promote the unblock efficiency.
Optionally, as shown in fig. 6, a first stopper 34 is disposed on a side of the mechanism base 3 close to the operation end 50.
One end of the elastic element 6 is fixed on the fixing rod 5, and the other end abuts against the first limit block 34.
Optionally, as shown in fig. 5, a limiting ring 53 is disposed on one side of the fixing rod 5 close to the fixing hole.
The mechanism seat 3 is provided with a second limiting block 35 matched with the limiting ring 53.
