[0019] See also Figure 1-5 , the utility model provides the following technical solutions:

[0020] Specifically, it refers to a new type of handheld tablet computer desktop support leg, comprising a tablet computer 1, two grooves 2 are provided on the back of the tablet computer 1, two legs 3 are provided in the two grooves 2, and a grip 4 is fixedly connected to the surface of the two legs 3 facing away from the tablet computer 1. When the legs 3 are rotated into the grooves 2, the user's hand can be inserted between the grip 4 and the tablet computer 1, so that the user can hold the tablet computer conveniently;

[0021] Specifically, a T-shaped slide groove 5 is provided on the inner wall of the groove 2, a T-shaped slider 6 is slidably connected in the T-shaped slide groove 5, and a rotating plate 7 is rotatably connected between the T-shaped slider 6 and the support leg 3. When the support leg 3 rotates, the rotating plate 7 can pull or push the T-shaped slider 6 to slide in the T-shaped slide groove 5;

[0022] Specifically, two connecting cavities 10 are provided at the bottom of the flat plate 1, and a supporting plate 9 is provided in the connecting cavity 10. One side of the supporting plate 9 slides through the front side of the flat plate 1, and two connecting shafts 11 are rotatably connected between the inner walls on the opposite sides of the connecting cavity 10. Two gears 12 are fixedly sleeved on the two connecting shafts 11. A tooth groove is provided on the surface of one side of the supporting plate 9 close to the gear 12. The supporting plate 9 is meshed and connected with the gear 12 through the tooth groove. Two pulleys 13 are fixedly sleeved on the two connecting shafts 11, and a belt 14 is connected between the two pulleys 13 for transmission;

[0023] Specifically, the two connecting cavities 10 are respectively in the same vertical position with the two grooves 2, and a pull rod 8 is fixedly connected to the surface of one side of the T-shaped slider 6 facing the connecting cavity 10, and the other end of the pull rod 8 slides through the connecting cavity 10, and one end of the pull rod 8 located in the connecting cavity 10 is fixedly connected to a rack 15, and the rack 15 is meshed with a gear 12 on the side away from the support plate 9. Therefore, when the pull rod 8 pulls and pulls the rack 15 to move, the rack 15 can synchronously mesh with the transmission gear 12 to rotate. At the same time, under the transmission of the two pulleys 13, the two gears 12 rotate synchronously, so that the meshing transmission support plate 9 can be moved. Therefore, after the support legs 3 are unfolded, the support plate 9 can be synchronously moved out of the front side of the tablet 1. In this way, when the handheld tablet is placed on the desktop, the support plate 9 forms a support for the front side of the tablet 1, and the angle between the tablet and the desktop becomes larger as much as possible, which causes the tablet to be unstable when placed on the desktop, and further ensures the stability of the tablet when placed on the desktop.

[0024] Specifically, a rotating shaft 31 is fixedly sleeved on one side of the support leg 3, and both ends of the rotating shaft 31 are rotatably connected to the inner walls of the groove 2 on both sides opposite to each other. Two control cavities 32 are provided on the inner wall of the shell of the flat plate 1, and the two control cavities 32 are respectively arranged on one side close to the two grooves 2. One end of the rotating shaft 31 rotates and penetrates into the control cavity 32, and one end of the rotating shaft 31 located in the control cavity 32 is fixedly connected with a control circular plate 33. Two built-in cavities 34 are provided in the flat plate 1, and a T-shaped card shaft 35 is provided in the built-in cavity 34. The vertical rod of the T-shaped card shaft 35 slides and penetrates into the control cavity 32. The vertical rod of the T-shaped card shaft 35 is located at the control cavity One end in the cavity 32 is hemispherical, and a plurality of slots are provided on the outer surface of the control circular plate 33, which coincide with one end of the T-shaped card shaft 35 located in the control cavity 32. A tension spring 36 is fixedly connected between the horizontal plate of the T-shaped card shaft 35 and the inner wall of the built-in cavity 34, and the tension spring 36 is movably sleeved on the outer surface of the vertical axis of the T-shaped card shaft 35. In this way, when the tension spring 36 is not affected by the tension force, the tension spring 36 will pull the T-shaped card shaft 35, so that the T-shaped card shaft 35 can be engaged with the slot on the control circular plate 33, thereby completing the restriction on the control circular plate 33 and avoiding the problem of the support foot 3 rotating in the groove 2 as much as possible;

[0025] When the user applies force to pull the support leg 3 to rotate, the rotating shaft 31 synchronously drives the control circular plate 33 to rotate. Since the end of the vertical axis of the T-shaped card shaft 35 located in the control cavity 32 is hemispherical, the card slot on the control circular plate 33 will squeeze the T-shaped card shaft 35, causing the T-shaped card shaft 35 to slide in the built-in cavity 34. At the same time, the tension spring 36 is stretched. When the support leg 3 rotates to the specified position, since there are multiple card slots, the vertical axis of the T-shaped card shaft 35 is in the same position as the card slot. At this time, the T-shaped card shaft 35 is again inserted into the card slot under the pull of the tension spring 36 to complete the fixation of the support leg 3.

[0026] The working principle of the new handheld tablet desktop support leg provided by the utility model is as follows: the user applies force to pull the support leg 3 to rotate out of the groove 2, the rotating plate 7 can pull or push the T-shaped slider 6 to slide in the T-shaped slide groove 5, and at the same time the pull rod 8 pulls the rack 15 to move, the rack 15 can synchronously engage the transmission gear 12 to rotate counterclockwise, and at the same time, under the transmission of the two pulleys 13, the two gears 12 synchronously rotate counterclockwise, so that the meshing transmission support plate 9 can be moved out of the front of the tablet 1.
