Abstract:
1. A position-limiting mechanism comprising: a first position-limiting element slidably configured on a main body for securing a first component to the main body; an elastic element having a first end and a second end, wherein the first end is directly connected to the first position-limiting element and the second end is directly connected to the main body; a second position-limiting element slidably configured on the main body for securing a second component to the main body; a knob slidably configured on the main body and movably connected to the first position-limiting element and the second position-limiting element, wherein when the knob slides relatively to the main body along a first direction, the knob drives the first position-limiting element to release the first component, and when the knob slides relatively to the main body along a second direction, the knob drives the second position-limiting element to release the second component; and the knob having a first sliding slot and a second sliding slot, the first position-limiting element and the second position-limiting element respectively having a first protrusion and a second protrusion, the first protrusion being inserted into the first sliding slot, the second protrusion being inserted into the second sliding slot, wherein when the knob slides relatively to the main body along the first direction, the knob pushes the first protrusion to drive the first position-limiting element to release the first component and the second sliding slot allows the knob to move relatively to the second protrusion along the first direction, and when the knob slides relatively to the main body along the second direction, the knob pushes the second protrusion to drive the second position-limiting element to release the second component and the first sliding slot allows the knob to move relatively to the first protrusion along the second direction.
