[0044] like Figure 1-Figure 2 As shown, the present application provides an arm bracket, comprising a fixing assembly 1, which is suitable for fixing the arm bracket at a certain place, so as to achieve the effect of lifting the arm;

[0045] The fixing assembly 1 includes an upper fixing plate 11 and a connecting plate 16 fixedly arranged on one side of the upper fixing plate 11. The lower end of the connecting plate 16 is fixedly provided with a lower fixing plate 15. The connecting plate 16 is fixedly arranged on one side of the upper fixing plate 11 and the lower fixing plate 15 so as not to affect the fixing operation of the fixing assembly 1.

[0046] At the same time, a threaded hole (not shown) is fixedly opened on the lower fixing plate 15, and a screw 13 is threadedly connected to the lower fixing plate 15. A handle 14 is fixedly provided on the end of the screw 13 away from the upper fixing plate 11, so that the screw 13 can slide on the lower fixing plate 15 by rotating the handle 14.

[0047] A splint 12 is fixed or rotatably provided on the end of the screw 13 away from the handle 14. The splint 12 is located directly below the upper fixing plate 11. When the handle 14 is turned, the screw 13 pushes the splint 12 close to the upper fixing plate 11 to form a clamping effect, thereby achieving a fixing operation. When the handle 14 is turned to cause the screw 13 to drive the splint 12 away from the upper fixing plate 11, the arm bracket can be quickly disassembled.

[0048] like Figure 1-Figure 5As shown, an adjustment end 5 is fixedly provided on one side of the connecting plate 16, and the adjustment end 5 is suitable for adjusting the angle and height of the arm bracket;

[0049] The adjustment end 5 includes a support platform 50 fixedly provided on one side of the connecting plate 16. A small hole (not shown in the figure) is fixedly opened on the support platform 50, and a lifting assembly 54 is rotatably provided on the support platform 50. The lifting assembly 54 is suitable for adjusting the height of the arm bracket to adapt to different arm positions.

[0050] The lifting assembly 54 includes a fixed block 542 rotatably mounted on the support platform 50, a connecting rod fixedly mounted on the lower end of the fixing block 542, the connecting rod passing through a small hole on the support platform 50, and a nut (not shown in the figure) fixedly mounted on the lower end of the support platform 50, a threaded hole fixedly opened at the bottom end of the connecting rod, a bolt passing through the threaded hole, a nut (not shown in the figure) fixedly mounted on one side of the bolt, and the connecting rod passing through the small hole on the support platform 50, while the bolt passes through the support platform 50 and fixes the support platform 50 to the fixing block 542 by locking the nut fixed on the lower end of the support platform 50;

[0051] It should be noted that when the rotating nut is away from the nut, the fixing block 542 can be rotated to adjust the angle, and when the rotating nut is close to the nut, the angle can be fixed.

[0052] At the same time, an upper guard plate 541 is rotatably provided on the fixed block 542, and a lower guard plate 540 is rotatably provided at a position away from the upper guard plate 541, and a connecting block 544 is rotatably provided at one end of the upper guard plate 541 and the lower guard plate 540 away from the fixed block 542;

[0053] At the same time, a stop bar 546 is fixedly provided on the upper guard plate 541 and the lower guard plate 540. When the arm bracket is adjusted in height, the connecting block 544 will rotate downward due to its own gravity, and the stop bar 546 can prevent the connecting block 544 from rotating, so that the connecting block 544 can always maintain a position parallel to the fixed block 542 in the vertical direction, so that the use of the arm bracket will not be affected when adjusting the height.

[0054] A mounting cavity is fixedly provided at the lower end of the lower guard plate 540 away from the blocking bar 546;

[0055] A small hole is opened on the inner wall of the installation cavity, and a movable block 543 is rotatably arranged on the small hole, and one end of the movable block 543 is a fixed end;

[0056] refer to Figure 5 At the same time, a fixing groove 547 is fixedly opened at one end of the mounting cavity close to the stop bar 546, and the fixing groove 547 is suitable for embedding the fixed end of the movable block 543;

[0057] At the same time, the end of the movable block 543 away from the fixed end is a protruding end, and a serrated end 545 is fixedly provided on the end of the fixed block 542 away from the support platform 50. The gears on the serrated end 545 are arranged in an arc shape on the fixed block 542, and the serrated end 545 is adapted to the protruding end of the movable block 543;

[0058] When adjusting the height, after fixing the fixing assembly 1 in a certain place, the staff can manually lift the upper guard plate 541 and the lower guard plate 540 to rotate around the fixed block 542. At the same time, it is necessary to adjust the position of the movable block 543 backward to separate the protruding end of the movable block 543 from the serrated end 545 so that the protruding end of the movable block 543 will not affect the lifting during the lifting.

[0059] When the lifting is to a suitable height, the protruding end of the movable block 543 can be used to engage with the serrated end 545 of the fixed block 542. When the protruding end of the movable block 543 abuts against the serrated end 545, the upper guard plate 541 and the lower guard plate 540 will rotate downward for a distance due to their own gravity until the fixed end of the movable block 543 is embedded in the fixed groove 547 fixed in the installation cavity. At this time, the movable block 543 will fix the upper guard plate 541 and the lower guard plate 540 at this height to achieve the lifting effect.

[0060] At the same time, the connecting block 544 will rotate downward due to its own gravity. At this time, the blocking bars 546 fixed on the upper guard plate 541 and the lower guard plate 540 can block the connecting block 544, so that the connecting block 544 can be fixed at this height, so that the arm bracket can be kept on the same horizontal line.

[0061] At the same time, a movable rod 52 is rotatably provided on the connecting block 544, and the movable rod 52 is suitable for adjusting the angle of the arm bracket;

[0062] The lower end of the movable rod 52 is fixedly provided with a connecting end (not shown in the figure), and the lower end of the connecting end is fixedly provided with a threaded hole (not shown in the figure), and a screw (not shown in the figure) is threadedly connected in the threaded hole;

[0063] At the same time, the connecting end passes through the connecting block 544 and is fixed to the connecting block 544 with a screw. When the screw is turned away from the connecting block 544, the movable rod 52 can be turned to adjust the angle of the arm bracket. When the screw is turned close to the connecting block 544, the movable rod 52 is fixed to the connecting block 544, thereby fixing the angle of the arm bracket.

[0064] A fixed rod 53 is fixedly provided at a position away from the connecting end of the movable rod 52. A thread is fixedly provided on the outer side of the fixed rod 53. An arm support 6 is threadedly connected to the fixed rod 53. The arm support 6 is suitable for direct contact with the arm.

[0065] After the staff has fixed the arm bracket at a certain location using the fixing assembly 1, they can manually lift the upper guard plate 541 and the lower guard plate 540 to rotate around the fixing block 542. When the arm bracket is raised to a comfortable height, the protruding end of the movable block 543 can be inserted into the serrated end 545 of the fixing block 542 to fix the height of the arm bracket.

[0066] At the same time, the movable rod 52 is rotated around the connecting block 544. After adjusting to a suitable angle, the screw is turned to fix the movable rod 52 and the connecting block 544, so that the arm bracket is fixed at a suitable angle.

[0067] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
