[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the calculator involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] Reference Figure 1-5 The utility model provides a calculator with a flip cover, comprising:

[0024] A computing keyboard 1, one side of which is hingedly connected to a computing screen 2, and a damping shaft is provided inside the hinged connection between the computing keyboard 1 and the computing screen 2;

[0025] The connection structure 3 includes an upper connection plate 31 and a lower connection plate 33, and the upper connection plate 31 and the lower connection plate 33 are respectively fixedly connected to the outer surface of the other side of the computer keyboard 1 and the computer screen 2. The connection structure 3 also includes a fixed magnet strip 32, and the fixed magnet strip 32 is fixedly connected to the inside of the lower end surface of the upper connection plate 31. A pull rod 34 is inserted into the inside of the middle position of the lower connection plate 33, and a spring 35 is sleeved on the outer surface of the pull rod 34, and a moving magnet strip 36 is fixedly connected to the upper end of the pull rod 34. The positions of the upper connection plate 31 and the fixed magnet strip 32 and the lower connection plate 33 and the moving magnet strip 36 correspond to each other. A moving groove is opened inside the upper end surface of the lower connection plate 33, and the length and width dimensions of the moving groove are the same as the length and width dimensions of the moving magnet strip 36, and the two ends of the spring 35 are respectively against the bottom surface of the inside of the moving groove and the bottom surface of the moving magnet strip 36. Figure 2 and Figure 3 As shown, when the device is in use, pulling the pull rod 34 can drive the movable magnet bar 36 to move inside the movable slot, so that the movable magnet bar 36 can be more stable when moving through this design, and the movable magnet bar 36 can reset itself through the elasticity of the spring 35;

[0026] A limiting ring is provided on the outer surface of the pull rod 34, and the upper end surface of the limiting ring is in contact with the bottom surface of the lower connecting plate 33. Figure 3 As shown, when the device is in use, the design can limit the distance that the pull rod 34 and the moving magnet bar 36 move in the moving groove through the limiting ring, and when the upper end surface of the limiting ring fits the bottom surface of the lower connecting plate 33, the upper end surface of the moving magnet bar 36 and the upper end surface of the lower connecting plate 33 are on the same horizontal line;

[0027] The clamping structure 4 includes a fixed clamping plate 41, and the outer surface of the lower end of the computing keyboard 1 is embedded in the inner surface of the upper end of the fixed clamping plate 41. The clamping structure 4 also includes a threaded rod 42, and the threaded rod 42 is connected to the inner surface of one side of the bottom surface of the fixed clamping plate 41 with a bearing. The outer surface of the threaded rod 42 is threadedly connected to a movable clamping plate 43, and connecting rods 44 are inserted into the inner surfaces of both ends of one side of the movable clamping plate 43. The upper end surfaces of the two groups of connecting rods 44 are fixedly connected to the two ends of the bottom surface of one side of the fixed clamping plate 41, and a limiting ring is arranged on the outer surface of the lower end of the connecting rod 44. Figure 4 As shown, when the device is in use, the design prevents the movable splint 43 from detaching from the outer surface of the connecting rod 44 through the limiting ring provided on the outer surface of the lower end of the connecting rod 44, and the two sets of connecting rods 44 make the movable splint 43 more stable when moving, and the movable splint 43 will not deflect.

[0028] Working principle: When the device is in use, first pull the pull rod 34 downward so that the pull rod 34 drives the movable magnet strip 36 to move downward inside the movable slot. At this time, the surfaces of the fixed magnet strip 32 and the movable magnet strip 36 are separated from each other. Then, the computing screen 2 can be hinged and rotated to use the device, and the elasticity of the spring 35 can make the pull rod 34 and the movable magnet strip 36 reset by themselves. When the device is finished, the computing screen 2 is hinged and rotated to close so that the surfaces of the upper connecting plate 31 and the lower connecting plate 33 are in contact with each other. At this time, the fixed magnet strip 32 and the movable magnet strip 36 are attracted to each other by magnetism, thereby making the computing keyboard 1 and the computing screen 2 in contact with each other through the connecting structure 3;

[0029] When the device is in use, the threaded rod 42 is rotated to move the movable splint 43. At this time, the movable splint 43 moves synchronously on the outer surface of the connecting rod 44. Then, the table edge is clamped and fixed by the fixed splint 41 and the movable splint 43. At this time, the computer keyboard 1 can be embedded in the inner part of the upper end surface of the fixed splint 41, thereby placing the computer keyboard 1 and the computer screen 2 through the clamping structure 4 to prevent the computer keyboard 1 and the computer screen 2 from falling and being damaged. The above is the entire working principle of the present invention.
