The invention discloses a clamping mechanism and an electronic device. The electronic device comprises a first body, a second body, a mobile module and the clamping mechanism, wherein the mobile module is arranged between the first body and the second body, so that the second body can slide or incline relative to the first body; the clamping mechanism comprises a first binder and a latch; the first binder is arranged on the first body; the latch is movably arranged on the mobile module; when the latch is coupled onto the first binder under the action of magnetic force, the second body can slide relative to the first body; and when the latch is uncoupled from the first binder due to the inclination of the second body, the latch interferes with the mobile module, so that the second body can not slide relative to the first body.
