Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of Taiwan application serial no. 113142030, filed on Nov. 4, 2024. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The disclosure relates to an electronic device. Description of Related Art The modern electronic device (for example, the laptop computer) includes two bodies and a pivot. The pivot, for example, may be a bellows-type pivot composed of a plurality of components. Since the structure of the bellows-type pivot is complex, the cost of the electronic device is increased, and the components of the pivot are prone to damage, that is unfavorable for the assembly and use of the electronic device. SUMMARY The disclosure provides an electronic device that is convenient to use. A electronic device of the disclosure includes a first body, a second body, a pivot module, and a connection casing. The second body may be pivotally connected to the first body. The pivot module includes a first connector, a second connector and a third connector connected in sequence. The first connector is connected to the first body, and the third connector is connected to the second body. The first connector and the second connector jointly form a first torsion portion, and the third connector and the second connector jointly form a second torsion portion. A rotational torque of the first torsion portion is smaller than a rotational torque of the second torsion portion. A part of the pivot module is movably located within the connection casing. The connection casing includes a first connection casing, a second connection casing, and a third connection casing. The first connection casing is movably connected to the first body and movably connected to the second connection casing. The third connection casing is movably connected to the second body and movably connected to the second connection casing. Based on the above, the rotational torque generated by the first torsion portion of the pivot module of the electronic device of the disclosure is different from the rotational torque generated by the second torsion portion, so that the actuation sequence of the first connector, second connector, and third connector of the pivot module may be controlled. The structure of the pivot module is simple, so as to reduce the cost of the electronic device and make the electronic device easy to assemble, making the electronic device convenient to use. The connection casing accommodates the pivot module, and the first connection casing and the third connection casing may move relative to the second connection casing to maintain the aesthetic appearance of the electronic device.
