[0020] The following is combined with Figures 1-3 This application is described in further detail.

[0021] The embodiment of the present application discloses a portable bracket.

[0022] Reference Figure 1 and Figure 2 The portable bracket includes a support arm 1, which is slidably connected to a bracket 2 through a connecting mechanism, a lower clamping block 3 is slidably connected to the bracket 2, a sliding rod 5 is fixedly arranged on the surface of the lower clamping block 3 facing the bracket 2, a sliding hole matching the size of the sliding rod 5 is opened on the bracket 2, and the sliding rod 5 is slidably connected in the sliding hole. The sliding hole limits the position of the sliding rod 5, reduces the possibility of position deviation of the lower clamping block 3 during movement, and improves the stability of the lower clamping block 3 during movement. In the embodiment of the present application, a cushion block 30 can also be set on the end surface of the bracket 2 away from the support arm 1. The cushion block 30 can be made of rubber material, which plays a buffering and shock-absorbing role while further improving the friction between the electronic device and the cushion block 30, thereby improving the stability of the electronic device mounted on the bracket 2.

[0023] ReferenceFigure 1 and Figure 2 On the bracket 2, a fixing mechanism for fixing the position of the lower clamping block 3 is provided. A upper clamping block 4 is slidably connected to the bracket 2. In the embodiment of the present application, the upper clamping block 4 and the lower clamping block 3 are located on the same straight line in the vertical direction. The upper clamping block 4 and the lower clamping block 3 are respectively provided with arc-shaped grooves oppositely. The electronic device is mounted on the bracket 2 and the electronic device is pressed against between the two arc-shaped grooves. The arc-shaped grooves play a role in limiting the electronic device placed on the bracket 2, and further improve the stability of the electronic device mounted on the bracket 2.

[0024] Referring to Figure 1 and Figure 2 As shown in FIGS. and, the fixing mechanism includes a threaded hole opened on the bracket 2. A fixing bolt 6 is inserted through and rotatably connected to the lower clamping block 3. In the embodiment of the present application, the end of the fixing bolt 6 is provided with a knob, and a plurality of convex ribs are provided on the outer edge of the knob, so as to facilitate the operator to conveniently grasp the fixing bolt 6 to adjust the position of the lower clamping block 3. The fixing bolt 6 is arranged in parallel with the sliding rod 5. The end of the fixing bolt 6 facing the bracket 2 is threadedly connected in the threaded hole. Therefore, when it is necessary to adjust the position of the lower clamping block 3 relative to the bracket 2, the operator rotates the fixing bolt 6. Since the fixing bolt 6 is threadedly connected to the threaded hole of the bracket 2, the position of the lower clamping block 3 can be adjusted according to the size of the electronic device, so as to facilitate dealing with electronic devices of different models and sizes.

[0025] Referring to Figure 1 and Figure 2 As shown in FIGS. and, the connecting mechanism includes a sliding groove 7 opened on the bracket 2. A slider 8 matching the size of the sliding groove 7 is slidably connected in the sliding groove 7. A limiting device for fixing the position of the slider 8 is provided on the bracket 2. The slider 8 is rotatably connected to the support arm 1 through a connecting device. The limiting device includes an adjusting block 10 rotatably connected in the slider 8 through a pin shaft 9. A pressing block 11 is fixedly connected to the adjusting block 10. The pressing block 11 partially extends out of the adjusting block 10 and a plurality of anti-slip convex ribs 31 are provided on the surface of the pressing block 11 facing away from the sliding groove 7. A plurality of adjusting grooves 12 are opened along the vertical direction of the bracket 2 at the bottom of the sliding groove 7. A fixing block 13 is fixedly connected to the surface of the adjusting block 10 facing the sliding groove 7. The fixing block 13 is inserted into one of the adjusting grooves 12. The pin shaft 9 is located between the fixing block 13 and the pressing block 11. An elastic reset rod 14 is fixedly connected to the surface of the adjusting block 10 facing the sliding groove 7. The elastic reset rod 14 abuts between the bottom of the sliding groove 7 and the pressing block 11.

[0026] Therefore, the operator presses the pressing block 11, the pressing block 11 squeezes the elastic reset rod 14, the position of the adjusting block 10 tilts to drive the fixing block 13 on the other side of the pin shaft 9 to lift, so that the fixing block 13 disengages from the adjusting groove 12, and the adjusting groove 12 releases the restriction on the position of the fixing block 13. Subsequently, the slider 8 can move along the direction of the sliding groove 7, and relative sliding occurs between the support arm 1 and the bracket 2, so that the bracket 2 can drive the electronic device to move along the support arm 1, improving the flexibility and the adjustable range of the electronic device at the same time.

[0027] Referring to Figure 1 and Figure 2 , the connecting device includes a connecting block 15 arranged on the slider 8. A connecting groove 16 matching the size of the connecting block 15 is formed on the support arm. The connecting block 15 is inserted into the connecting groove 16. A connecting bolt 17 passing through the connecting groove 16 and the connecting block 15 is provided on the support arm. An external thread of the connecting bolt 17 is threadedly connected with a connecting nut 18 matching the size of the connecting bolt 17. The support arm 1 is abutted between the end of the connecting bolt 17 and the connecting nut 18. Therefore, when it is necessary to adjust the angle of the connecting block 15 relative to the support arm 1, the operator rotates the connecting nut 18 to create a gap between the connecting block 15 and the connecting groove 16, and the connecting block 15 can adjust its position in the connecting groove 16, so as to realize the adjustable angle of the connecting block 15 relative to the support arm 1, improving the flexibility between the support arm 1 and the connecting block 15 and the applicable range of the angle of the portable bracket.

[0028] Referring to Figure 1 and Figure 3 , a plurality of fixing grooves 19 are formed on the support arm. A plurality of limiting blocks 20 are fixedly connected to the surface of the connecting block 15 facing the fixing grooves 19. The plurality of limiting blocks 20 are inserted into the fixing grooves 19. Therefore, the fixing grooves 19 play a role in limiting the position of the limiting blocks 20, reducing the possibility of position deviation between the connecting block 15 and the support arm 1, and further improving the connection stability between the connecting block 15 and the support arm 1.

[0029] Referring to Figure 1 and Figure 2 , the support arm 1 is connected with a fixing seat 21 through an adjusting mechanism. In the embodiment of the present application, the fixing seat 21 can be connected to other components on the operator's chest, such as a wearable waist belt, etc., so as to fix the bracket 2 on the operator's chest.

[0030] Referring to Figure 1 and Figure 2, The adjusting mechanism includes a support base 22 provided on the fixed base 21. A rotating groove 23 matching the size of the support arm 1 is formed on the surface of the support base 22 facing the support arm 1. One end of the support arm 1 facing the fixed base 21 is rotatably connected in the rotating groove 23. A fixing device is provided on the support base 22 for fixing the rotation angle of the rotating arm relative to the support base 22. The fixing device includes a mounting block 24 provided on the support base 22. A placement hole 25 is formed in the mounting block 24. A compression spring 29 is placed in the placement hole 25. A number of ball grooves 26 are formed on the support arm 1. A steel ball 27 is provided between the placement hole 25 and one of the ball grooves 26. A control component for controlling the elastic degree of the compression spring 29 is provided in the placement hole 25. The control component includes an adjusting bolt 28 threadedly connected in the placement hole 25. The compression spring 29 abuts between the steel ball 27 and the adjusting bolt 28. The operator can rotate the adjusting bolt 28 to change the pressing degree of the adjusting bolt 28 on the compression spring 29, thereby adjusting the elastic force of the compression spring 29.

[0031] Therefore, when the electronic device is normally mounted on the bracket 2, the self-weight of the electronic device is less than the elastic force of the compression spring 29. The compression spring 29 abuts against the steel ball 27 and is fixed at this position. When an external force greater than the elastic force of the compression spring 29 is applied to the support arm 1, the support arm 1 rotates in the rotating groove 23 and squeezes the steel ball 27. The steel ball 27 squeezes the compression spring 29, enabling the support arm 1 to rotate under the action of the external force, completing the angle adjustment of the support arm 1 relative to the fixed base 21, and realizing the function of automatically retracting the support arm 1 when the operator faces the ground and tilts.

[0032] The implementation principle of the embodiment of the present application is as follows: The operator mounts the electronic device on the bracket 2 and fixes the electronic device through the upper clamping block 4 and the lower clamping block 3. When it is necessary to adjust the relative position between the support arm 1 and the bracket 2, the operator presses the pressing block 11. The pressing block 11 squeezes the elastic reset rod 14. The position of the adjusting block 10 tilts to drive the fixing block 13 on the other side of the pin shaft 9 to lift, so that the fixing block 13 disengages from the adjusting groove 12. The adjusting groove 12 releases the restriction on the position of the fixing block 13. Subsequently, the slider 8 can move along the sliding groove 7 direction, and relative sliding occurs between the support arm 1 and the bracket 2, so that the bracket 2 drives the electronic device to move along the support arm 1, which is more flexible and improves the adjustable range of the electronic device.
