Movable lever

The utility model provides a movable lever, which is used for embedding or removing a computer element from a shell module of a server rack, and comprises a central rotatable structure, a long arm connected with the central rotatable structure and a first direction extending to be far away from the central rotatable structure, and a short arm connecting and extending to a second direction away from the central rotatable structure. The central rotatable structure includes a rotation blocking member for limiting rotation of the central rotatable structure along the rotation axis between an embedded position and a removed position. The central rotatable structure also includes a retaining structure for maintaining coupling of the central rotatable structure with the tray when the central rotatable structure is in the other non-embedded position. The short arm is configured to engage a side wall of the housing module when the central rotatable structure is rotated along the axis of rotation. 本实用新型提供了一种可移动杠杆，用于自服务
