[0019] A lock device applied to a server, comprising a shell 1, a clamping tongue 2, a handle 3, a hinged piece 4 and a locking mechanism arranged in the shell 1, the clamping tongue 2 and the shell 1 are in sliding connection, the shell 1 is provided with an opening 1a for the clamping tongue 2 to pass out, one end of the handle 3 is in rotational connection with the clamping tongue 2, one end of the hinged piece 4 is in hinged connection with the shell 1, meanwhile, the other end of the hinged piece 4 is in rotational connection with the handle 3, for restricting the handle 3 to only make linear movement in one direction when locking, the locking mechanism is in clamping and fixing with the handle 3 embedded into the shell 1, characterized in that the shell 1 is provided with a notch structure 1b, the linear length direction of the notch structure 1b is opposite to the opening 1a, the end of the clamping tongue 2 adjacent to the opening is a tongue piece 21, the end of the handle 3 is connected with the tongue piece 21 through a shaft body 5, the shaft body 5 passes through the notch structure 1b, so that the handle 3 makes linear movement following the sliding of the shaft body 5 in the notch structure 1b.

[0020] The utility model discloses the beneficial effects of:

[0021] The utility model discloses the notch structure 1b in the shell 1 for limiting the clamping tongue 2 connected with the shaft body 5, the notch structure 1b plays a guiding role, and the movement direction of the clamping tongue 2 is restricted, in other words, under the action of the notch structure 1b, the clamping tongue 2 will not shake, therefore, the opening 1a will not rub or interfere with the shell 1, and the smoothness of the movement of the clamping tongue 2 is ensured.

[0022] Specifically, the hinged seat 2a is formed on the clamping tongue 2, and the connecting part matched with the hinged seat 2a is arranged at the end of the handle 3, and the shaft body 5 passes through the connecting part and the hinged seat 2a at the same time, the hinged seat 2a and the connecting part matched with each other are arranged to improve the connection effect between them and ensure better stability during use.

[0023] During unlocking, to ensure that the latch 2 has a reset effect, a first torsion spring (not shown in the figure) is fitted on the shaft 5. One end of the first torsion spring abuts against the back of the handle 3, and the other end abuts against the inner surface of the outer shell 1. In the locked state, the handle 3 is embedded in the outer shell 1, and the first torsion spring is also compressed. During unlocking, the first torsion spring will automatically spring open the handle 3, forcing the latch 2 to reset. In this way, the handle 3 can be rotated out of the outer shell 1, which is beneficial to the use of the handle 3.

[0024] The aforementioned locking mechanism includes a button 6, a second torsion spring (not shown in the figure), and a latching member 31 extending outward on the head end of the handle 3.
