[0022] The following is combined with Figure 1 —7 provides further details of this application.

[0023] The embodiment of the present application discloses a joint hinge, including a joint support plate 1, a first through hole 11 is provided on the upper surface of the joint support plate 1, two slots 12 are provided on the upper surface of the joint support plate 1, an arc groove 13 is provided on the upper surface of the joint support plate 1 and the bottom surface of the joint support plate 1, a group of semicircular grooves 15 are provided on the upper surface of the joint support plate 1 and the bottom surface of the joint support plate 1, and the inner wall of each semicircular groove 15 is rotatably connected to a ball 14, and two second through holes 21 are provided on the upper surface of the joint support plate 2. The slots 12 can facilitate the installation and positioning of the upper adjustment member 5 to prevent the upper adjustment member 5 from sliding left and right, and the balls 14 can make the rotation of the joint support plate 1 smoother to prevent the occurrence of jamming.

[0024] Two first positioning holes 31 are provided on the upper surface of the chuck 3, and a second positioning hole 33 is provided on the upper surface of the chuck 3. Teeth 32 are provided on the outer surface of each chuck 3. The two chucks 3 are fixedly connected to the side surfaces close to each other with columns 34. The two columns 34 extend to the inside of the two arc-shaped grooves 13 respectively. The second positioning hole 33 and the first positioning hole 31 can facilitate the chuck 3 to coaxially connect the joint support plate 1 and the joint support plate 2 2. The arc groove 13 and the column 13 can be used to limit the rotation range of the first joint support plate 1 to prevent the teeth 32 from detaching from the first tooth plate 53.

[0025] A chuck 3 is provided above and below the joint support plate 1. The two chucks 3 are fixed to the joint support plate 1 and the joint support plate 2 2 respectively through a group of fixing parts 4. The fixing parts 4 include bolts 41 and nuts 42. The bottom ends of a group of bolts 41 are threadedly connected with a group of nuts 42 respectively. The bolts 41 and nuts 42 can facilitate the rotation of the joint support plate 1 after connection. The outer surface of the joint support plate 1 is provided with an upper adjusting part 5, and the outer surface of the joint support plate 1 is provided with a lower adjusting part 6. The upper adjusting part 5 is clamped with the lower adjusting part 6, and the upper adjusting part 5 and the lower adjusting part 6 are respectively engaged with the two chucks 3.

[0026] See also Figure 6 The upper adjusting member 5 includes two side edges 51 and two guide blocks 56. The front and back sides of each guide block 56 are fixedly connected to a first clamping column 54. Two sets of grooves 52 are provided on the bottom surface of the upper adjusting member 5. The right side of the upper adjusting member 5 is fixedly connected to a first tooth plate 53. The first tooth plate 53 is engaged with the teeth 32. The side surfaces of the two guide blocks 56 close to each other are fixedly connected to a first limiting block 55. The guide block 56 is placed inside the card slot 12 to perform a preliminary positioning of the upper adjusting member 5, and the first limiting block 55 is used to limit the guide block 56 so that when the guide block 56 moves upward, the first limiting block 55 is released from the bottom surface of the joint support plate 1 to prevent it from falling off.

[0027] In this embodiment, the lower adjusting member 6 includes two groups of guide bars 65 and a second tooth plate 61. The second tooth plate 61 is meshed with the teeth 32. The side of the two groups of guide bars 65 that are close to each other is fixedly connected with a second limit block 63. The second limit block 63 is released from the upper surface of the joint support plate 1 to limit the guide bar 65. The side of the two groups of guide bars 65 that are close to each other is fixedly connected with a second clamping column 62. Two receiving grooves 64 are provided on the upper surface of the lower adjusting member 6. The two guide blocks 56 extend between the two receiving grooves 64. The two groups of first clamping columns 54 are respectively clamped with the two groups of second clamping columns 62. The receiving grooves 64 can be used to accommodate the guide blocks 56 so that the guide blocks 56 can position the lower adjusting member 6. The first clamping column 54 and the second clamping column 62 can be used to clamp the upper adjusting member 5 with the lower adjusting member 6, thereby ensuring the positioning of the chuck 3.

[0028] The implementation principle of the joint hinge of the embodiment of the present application is as follows: when in use, by pulling the side 51, an upward pulling force is applied to the upper adjustment member 5, and the upper adjustment member 5 drives the first clamping column 54 to move upward, so that the first clamping column 54 is separated from the second clamping column 62, thereby releasing the clamping connection between the upper adjustment member 5 and the lower adjustment member 6, so that the first tooth plate 53 is separated from the teeth 32 on the chuck 3, and then the lower adjustment member 6 is pulled, so that the lower adjustment member 6 drives the second tooth plate 61 to move downward and separate from the chuck 3, thereby releasing the lock on the chuck 3;

[0029] The joint support plate 1 and the joint support plate 2 can be rotated by the bolt 41 and the nut 42 to adjust the angle. After the adjustment, the upper adjusting member 5 and the lower adjusting member 6 can be pushed closer to each other, so that the first clamping column 54 and the second clamping column 62 are clamped, and the first tooth plate 53 and the second tooth plate 61 cooperate with the teeth 32 to limit the chuck 3, so that the angle can be more flexible.

[0030] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
