Technical Field

The invention belongs to the technical field of servers, and particularly relates to a server node tool-free handle lock and a server.

Background

The server has high-speed CPU computing capability, long-time reliable operation, strong I/O external data throughput capability and better expansibility. Generally, a server has the capability of responding to a service request, supporting a service, and guaranteeing the service according to the service provided by the server.

For a multi-node server, at least two node modules are usually installed inside the server, each node module can be extracted from a server chassis, and each node needs to be positioned and installed on the server chassis to ensure the installation stability and the operation reliability of the server node.

Because many nodes exist in the multi-node server, the nodes need to be pulled out independently for maintenance during maintenance. The traditional pulling-out and unlocking process of the server node is particularly complex, and great waste of labor and time cost can be caused. And the traditional server node positioning locking structure has larger volume, can greatly occupy the internal space of the node, and does not accord with the high-density design principle of the server node.
