• an upper end of the second slope is provided with a second upper limiting platform;
• and
• the second upper limiting platform is configured to support the first lower limiting platform and confine the second sleeve to the second position;
• the hinge further comprises a first buffer sleeve sleeved on the hinge shaft;
• the first buffer sleeve is coupled to the second installation plate and provided between the first sleeve and the second sleeve;
• both ends of the first buffer sleeve include cylindrical walls respectively configured to abut against the first sleeve and the second sleeve;
• an outer cylindrical wall of the first buffer sleeve is provided with a reinforcement block, the reinforcement block being located between the first installation plate and the second installation plate, and the reinforcement block is provided with an avoidance area for avoiding the first installation plate;
• and
• a clamping slot is provided on a side of the reinforcement block away from the avoidance area, and the second installation plate is clamped by the clamping slot.

A hinge, comprising:

• a hinge shaft, a first hinge base, and a second hinge base, wherein:
• the hinge shaft is vertically arranged;
• the first hinge base includes a first installation plate and a first sleeve coupled to the first installation plate, wherein the first sleeve is sleeved on the hinge shaft and rotatably coupled to the hinge shaft to enable the first sleeve to rotate around the hinge shaft, and a lower end of the first sleeve is provided with a first slope sloping downwards;
• and
• the second hinge base is arranged below the first hinge base and includes a second installation plate and a second sleeve coupled to the second installation plate, wherein:
• the second sleeve is sleeved on the hinge shaft and fixed on the hinge shaft;
• and
• an upper end of the second sleeve is provided with a second slope sloping upwards, and when the first sleeve rotates around the hinge shaft, the second slope is abutted against and cooperated with the first slope to make the first sleeve being moved from a first position to a second position and away from the second sleeve or from the second position to the first position and close to the second sleeve,
• wherein:
• a lower end of the first slope is provided with a first lower limiting platform;
• an upper end of the second slope is provided with a second upper limiting platform;
• and
• the second upper limiting platform is configured to support the first lower limiting platform and confine the second sleeve to the second position;
• the hinge further comprises a first buffer sleeve sleeved on the hinge shaft;
• the first buffer sleeve is coupled to the second installation plate and provided between the first sleeve and the second sleeve;
• both ends of the first buffer sleeve include cylindrical walls respectively configured to abut against the first sleeve and the second sleeve;
• an outer cylindrical wall of the first buffer sleeve is provided with a reinforcement block, the reinforcement block being located between the first installation plate and the second installation plate, and the reinforcement block is provided with an avoidance area for avoiding the first installation plate;
• and
• a side of the reinforcing block facing the avoidance area is provided with a second limiting slot corresponding to the second upper limiting platform, and a groove wall of the second limiting slot is configured to abut against the second installation plate to limit the second installation plate.

A hinge, comprising:

• a hinge shaft, a first hinge base, and a second hinge base, wherein:
• the hinge shaft is vertically arranged;
• the first hinge base includes a first installation plate and a first sleeve coupled to the first installation plate, wherein the first sleeve is sleeved on the hinge shaft and rotatably coupled to the hinge shaft to enable the first sleeve to rotate around the hinge shaft, and a lower end of the first sleeve is provided with a first slope sloping downwards;
• and
• the second hinge base is arranged below the first hinge base and includes a second installation plate and a second sleeve coupled to the second installation plate, wherein:
• the second sleeve is sleeved on the hinge shaft and fixed on the hinge shaft;
• and
• an upper end of the second sleeve is provided with a second slope sloping upwards, and when the first sleeve rotates around the hinge shaft, the second slope is abutted against and cooperated with the first slope to make the first sleeve being moved from a first position to a second position and away from the second sleeve or from the second position to the first position and close to the second sleeve,
