Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of Taiwan application serial no. 113142681, filed on Nov. 7, 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 application relates to a device, and in particular, to an electronic device. Description of Related Art FIG. 1 is a schematic diagram illustrating a pivot of a conventional electronic device fixed to the casing. Referring to FIG. 1, in the conventional electronic device, one end 112 of the locking piece 11 of the pivot 1 covers the rotating shaft 12, and the other end 114 is locked on the protruding locking platform 21 inside the casing 2. The part between the two ends of the locking piece 11 is supported on the surface 2a of the casing 2. However, although part of the locking piece 11 is supported on the casing 2 to provide supporting force, the height of the locking platform 21 protruding from the surface 2a of the casing 2 is quite high, resulting in a longer overall length of the locking piece 11. This causes the locking piece 11 to provide a large torque to the rotating shaft 12. Therefore, when the screen-side is opened or closed relative to the logic end, there is a noticeable shaking sensation. SUMMARY The electronic device of the application has rotational stability when the first body rotates relative to the second body. The application provides an electronic device, including a first body, a second body, and a hinge structure. The second body includes a first casing and a second casing. The first casing has a surface facing the second casing and a first step and a second step protruding from the surface, wherein the height of the first step is greater than the height of the second step. The hinge structure includes a rotating shaft and a locking piece. The rotating shaft is connected to the first body and the second body. The locking piece is adjacent to the rotating shaft and has a first assembly part, a second assembly part, and a third assembly part sequentially connected. The first assembly part is supported and fixed on the first step, while the second assembly part is supported and fixed on the second step. The third assembly part covers at least a portion of the rotating shaft. Based on the above, in the electronic device of the application, by adjusting the step difference range between the heights of the first step and the second step set on the first casing, the stability of the first body rotating relative to the second body of the electronic device may be improved. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram illustrating a pivot of a conventional electronic device fixed to the casing. FIG. 2 is a three-dimensional schematic diagram of the electronic device. FIG. 3 is a local schematic diagram of the electronic device of FIG. 2. FIG. 4 is a schematic diagram illustrating the first step and the second step spaced apart by a distance. DESCRIPTION OF THE EMBODIMENTS FIG. 2 is a three-dimensional schematic diagram of the electronic device, and FIG. 3 is a local schematic diagram of the electronic device of FIG. 2. Referring to FIG. 2 and FIG. 3 at the same time, the electronic device 3 of the embodiment includes a first body 4, a second body 5, and a hinge structure 42. In an implementation, the first body 4 has a screen 41, and the second body 5 is a system host. However, the application is not limited to this. The second body 5 includes a first casing 51 and a second casing 52, wherein the second casing 52 is assembled with the first casing 51 to jointly construct an accommodation space (not marked), and electronic components such as the motherboard (not marked) and memory (not marked) are set in this accommodation space. The first casing 51 has a surface 51a faced towards the second casing 52 and a first step 511 and a second step 512 protruding from the surface 51a, wherein the height of the first step 511 is greater than the height of the second step 512. The hinge structure 42 is set at a side where the first body 4 and the second body 5 approach each other, wherein the hinge structure 42 pivotally connects the first body 4 and the second body 5 together, enabling the first body 4 and the second body 5 to open and close relative to each other. The aforementioned hinge structure 42 includes a rotating shaft 421 and a locking piece 422. The locking piece 422 has a first assembly part 4221, a second assembly part 4222, and a third assembly part 4223, wherein the first assembly part 4221 supports and is fixed to the first step 511. While the second assembly part 4222 supports and is fixed to the second step 512, and the third assembly part 4223 covers at least a portion of the rotating shaft 421. In the embodiment, the first step 511 protrudes from the surface 51a by approximately 2.6 mm, while the step difference range between the first step 511 and the
