New type description: [Technical field to which the new type belongs] This creation relates to a supporting device, especially a supporting device for supporting a notebook computer. [Previous technology] Due to the thinness, compactness, and portability of pen-type computers, they have gradually become popular with consumers and are used. However, notebook computers are thin and do not provide supporting components, so they can only be placed flat on a table or On the desktop. Often, the display screen and the location where it is deployed are not suitable for use. For example, the viewing angle is too low, which causes the user's eye fatigue and uncomfortable viewing posture. In addition, when the keyboard is placed on the desktop, after a long-term use, the user may experience discomfort such as wrist fatigue, which causes inconvenience. Therefore, in order to solve the above-mentioned problems of the notebook computer, a notebook computer supporting device has appeared in the industry, such as a simple notebook computer auxiliary support disclosed in the Republic of China Patent Application No. 88217785, which includes a support and a support block. . The support base is a one-piece body, the front side is provided with an arc groove, and the other side is provided with a cut groove to form a convex seat and a pressing block. The boss is provided with a screw hole, and a pressing bolt is set in the screw hole. The pressing bolt can push the pressing block to cause the pressing block to interact and deform the arc groove. The support block is a flat strip on one side, and the bottom surface is provided with an integral protruding connecting block. The shape of the connecting block and The arc groove of the support base is corresponding, and can be buckled in the arc groove, so that the support block is integrated with the support base, and the support block arc is pushed and rotated by the connecting block of the support block. To make the support block at an oblique angle, and cooperate with the pressing bolt to press the pressing block against the connection block, while maintaining the support block at the predetermined tilt angle, 6 M272132 is provided for supporting the notebook computer at the tilt angle. However, the notebook computer-assisted support can only provide a small range of viewing angle adjustment. Another example is the notebook computer support device disclosed in US Patent No. 5,503,361, which can adjust the viewing angle of use within a wide range. The notebook computer supporting device includes a first fixing plate for placing the notebook computer, a money chain, a second fixing plate rotatably fixed to the first fixing plate by the hinge, and an angle adjusting device. The outer ends of the second fixing plate and the second fixing plate are placed on a table to form a triangular supporting structure. A rubber pad and a groove are provided on the back of the display screen of the notebook computer, and corresponding protrusions and slots are correspondingly provided on the first fixing plate. A sliding groove is provided on the second fixing plate. The angle adjusting device includes a plurality of positioning holes and a connecting plate provided on both sides of the chute. A first end of the connecting plate is pivotally connected to the first fixing plate, and a second end of the connecting plate is connected with a positioning pin that can slide in the chute and can be positioned in the positioning hole by a spring. By changing the positions of the positioning pins in the positioning holes of the two fixing plates, the angle between the first fixing plate and the second fixing plate can be adjusted to increase or decrease the viewing angle of the notebook computer. However, the Yuanyuan pen type computer support device will occupy a large space during use. In addition, the accuracy of the angle adjustment of the notebook computer is limited by the number of positioning holes and the spacing distance in the second fixing plate. Therefore, it is necessary to improve the conventional notebook computer supporting device to eliminate the above-mentioned defects. [New content] The purpose of this creation is to provide a notebook computer support device that can arbitrarily adjust the viewing angle and save space. .M272132 This creative pen and computer support device, including m to put the notebook computer's proven rotating dislocation wire and-actuating device.
