The hinge module as claimed in claim 1, further comprising a second switching component, including: A bracket has a first slide rail and is sleeved on the first rotating shaft and the second rotating shaft; A fixed block having a second slide rail and sleeved on the first rotating shaft and the second rotating shaft; a first cam passing through the second rotating shaft and clamped between the bracket and the fixed block; a second cam passing through the first rotating shaft and clamped between the bracket and the fixed block; and a slider clamped between the bracket and the fixed block, and including a body portion, a first sliding portion and a second sliding portion, wherein the first sliding portion and the second sliding portion protrude from opposite sides of the body portion, the body portion abuts between the first cam and the second cam, the first sliding portion slides on the first slide rail, and the second sliding portion slides on the second slide rail.

10. The hinge module of claim 9, wherein the first cam includes a first abutment portion, the second cam includes a second abutment portion, and the slider includes a slider abutment portion corresponding to the first abutment portion and the second abutment portion.

11. The hinge module as claimed in claim 1, wherein the second slider has a second groove, and one end of the sliding frame slides in the second groove.

12. An electronic device comprising: The first body; A second body; A connecting body has a first side and a second side opposite to each other, wherein the first body is pivotally connected to the first side; The system includes at least one hinge module, comprising: a first pivot connected to the second body; a second pivot connected to the second side; a limiting assembly, comprising: a limiting member including a first limiting portion through which the first pivot and the second pivot pass; a first sliding member slidably disposed on the first pivot and including a first rack portion and a second limiting portion corresponding to the first limiting portion; a gear rotatably disposed on the limiting member and having a first side and a second side opposite to each other, the first side being movably connected to the first rack portion; a second sliding member slidably disposed on the second pivot and including a second rack portion movably connected to the second side; and a switching assembly, comprising: a sliding frame connected to the second sliding member and slidable relative to the second pivot; a driving member movably connected to the sliding frame and the second pivot; and an elastic member disposed between the sliding frame and the second pivot.
