[Prior Art] The electronic device of the prior art, taking a notebook computer as an example, usually has a hinge for connecting the screen and the main body, and the hinge is divided into a single hinge and a double hinge for the user to open the notebook in a rotating manner. Among them, the conventional single hinge form can only provide the adjustment of the single angle between the screen and the main body. The position of the screen cannot be fine-tuned, especially when the rotation angle is greater than 90 degrees and the screen is heavy, it may be due to notes. The relationship between the center of gravity of the computer and the backward movement of the computer causes the computer to tilt toward the rear of the screen, thus causing inconvenience in use. The form of the double hinge can be adjusted by the use of two hinges for two angles of opening and closing, so that the screen angle can be adjusted in detail. However, in order to limit the opening angle of the hinge to a reasonable extent, the maximum rotation angle is usually designed, and when this angle is reached, the rotation cannot be continued. However, in the prior art, such a structure that limits the maximum angle of rotation of the hinge is directly designed on the hinge, making it difficult to repair in the event of damage. In addition, when the angle of rotation of the hinge connected to the main body of the computer is too small, if the screen is directly pulled out, the screen may be damaged by the screen. In addition, when both hinges in the form of double hinges are rotated, if the 5 M316424 - directly pulls back the screen, the screen will also hit the body and cause damage. - Therefore, it is necessary to provide an electronic device having a rotating structure to improve the problems of the prior art. [New Content] - The purpose of this creation is to provide an electronic device with a rotating structure that limits the angle of rotation of the hinge. To achieve the above object, an electronic device having a rotating structure of the present invention includes a main body, a first connecting portion, a second connecting portion, and a third connecting portion. Wherein, the first connecting portion includes a first hinge, and the first hinge connects the main body, and the first connecting portion is rotatable relative to the main body. The second connecting portion includes a second hinge and a chute, and the second hinge connects the main body, and the second connecting portion is rotatable relative to the main body. The first hinge and the second hinge are not at the same axis, such that when the second connecting portion rotates relative to the main body, the first connecting portion slides in the sliding groove, and the sliding position includes the locking position and the releasing position. The third connecting portion includes a third hinge and a fastener, and the third hinge connects the second connecting portion, and the card is fastened to the first connecting portion when the card is in the fixed position. When the second connecting portion rotates relative to the main body by less than the first predetermined angle, the sliding portion is located at the locking position, and the third connecting portion cannot rotate relative to the second connecting portion; when the second connecting portion rotates relative to the main body is greater than the first When the angle is predetermined, the sliding portion slides to the releasing position, and at this time, the third connecting portion is rotatable relative to the second connecting portion. The second connecting portion includes a first stopping portion and a second stopping portion. 6 M316424 - the first connecting portion abuts against the first stopping portion when the second connecting portion and the main body increase the relative rotation angle to the second predetermined angle; when the fastener is separated from the first connecting portion _, the first connecting portion is abutted The gear is in the second stop, and the second connecting portion cannot reduce the relative rotation angle with the main body.
