The first end of the torsion spring 15 abuts against the lock seat 8 and the second end abuts against the lock 7.

[0045] In the above structure, when the push rod 3 pushes the lock catch 7 to rotate, the torsion spring 15 is compressed and stored. After the drawer 2 is automatically ejected, the motor 30 is automatically powered off, and the push rod 3 is automatically retracted and reset. At this time, the torsion spring 15 releases its elastic force to make the lock catch 7 rotate in the opposite direction and reset. In addition, the various components of the lock catch assembly in the above structure cooperate with each other, which is easy to assemble and has stable rotation.

[0046] Further, if Fig. 9 The second end of the torsion spring 15 abuts against the locking portion 72 of the lock buckle 7, and the locking portion 72 is used to position the second end of the torsion spring 15, which has a simple structure and is easy to assemble.

[0047] Further, if Fig. 9 The lock 7 includes two symmetrically arranged rotating shafts 71, and the pin 14 and the torsion spring 15 also include two symmetrically arranged ones.
