Description

TECHNICAL FIELD The present disclosure relates generally to a lifting device, and more particularly, to a linkage mechanism and a lifting device for storage enclosures or other systems. BACKGROUND For an electronic or storage system like a server, an enclosure or a chassis is often provided to include or store multiple modules, such as storage module(s), power supply unit(s), cooling module(s), etc. Certain modules may be mounted (e.g., stacked within the chassis) such that it is difficult to access one or more of the multiple modules. SUMMARY Techniques are described herein for a linkage mechanism or a lifting device having one or more linkage mechanisms (e.g., a first linkage mechanism and/or a second linkage mechanism). The first and second linkage mechanism may, or may not, have mirrored structures. The linkage mechanism (e.g., the first linkage mechanism or the second linkage mechanism) may include a first linkage member and/or a second linkage member. The second linkage member may be directly or indirectly coupled to the first linkage member. The linkage mechanism may further include a first group of stopping structures (e.g., a stopping shaft) that stops the first linkage member (and therefore the second linkage member) at a first position (e.g., a lifted position). The linkage mechanism may additionally or alternatively include a second group of stopping structures (one or more stopping members, which may be aligned with each other) to stop the first linkage member (and therefore the second linkage member) at a second position (e.g., a retracted position). According to one aspect of the present disclosure, a linkage mechanism is provided. The linkage mechanism may include: a supporting component, a connecting unit, and/or a fixation base. The connecting unit may include a first linkage member movable between a lifted position and a retracted position. The first linkage member may include a first body portion to connect with the fixation base and a first end portion to connect with the first supporting component. In some embodiments, the first body portion of the first linkage member may be integrated with the first end portion of the first linkage member to form approximately an L shape. In some embodiments, the fixation base includes a first protruding stopping element (e.g., the aforementioned stopping shaft) to stop the first linkage member at the lifted position. In some embodiments, the first body portion of the first linkage member may include a stop notch to engage with the first protruding stopping element. In some embodiments, the fixation base may include a plate region and a protruding region that protrudes from the plate region. In some embodiments, the first protruding stopping element that is configured to stop the first linkage member at the lifted position may be disposed on the protruding region of the fixation base. In some embodiments, the fixation base may additionally, or alternatively, include one or more stopping members to stop the first linkage member at the retracted position. In some embodiments, the one or more stopping members may be disposed on the plate region of the fixation base. In some embodiments, the supporting component may include an opening portion (shortly as “opening”) that provides access to a finger-grab portion of the supporting component. In some embodiments, the fixation base may include a first protruding shaft member to engage with a first pivoting-connection hole that is at the first body portion of the first linkage member, thereby enabling the first body portion to be connected with the fixation base. In some embodiments, the first protruding shaft member may be disposed on the fixation base, e.g., in proximity to the first protruding stopping element. In some embodiments, the connecting unit may include a second linkage member configured to move in response to the first linkage member being moved. In some embodiments, the second linkage member may include a second body portion and a second end portion. In some embodiments, the second body portion of the second linkage member may be integrated with the second end portion of the second linkage member to form approximately an L shape. As used in the present disclosure, the terms “approximately” or “substantially” are meant to cover any normal fluctuations or deviations (e.g., ±20% or other applicable deviation percentages or degrees) appreciated by one of ordinary skill in the relevant art. In some embodiments, the fixation base may include a second protruding shaft member to engage with a second pivoting-connection hole that is at the second end portion of the second linkage member, thereby enabling the second end portion of the second linkage member to connect with the fixation base. In some embodiments, the first body portion of the first linkage member is integrated with the first end portion of the first linkage member to form approximately an L shape. In some embodiments, the first end portion
