When the robotic arm is used, the arm body 4 is mounted and fixed to the surface of the base 1, and then the arm body 4 grabs the object away from the side of the base 1, and then the grabbed object is moved by rotating the arm body 4. When changing the height of the base 1 so that the arm 4 can grab and move objects at different heights, the pad 25 can be moved first to make the pad 25 disengage from between the base 1 and the adjustment plate 24, and then the threaded rod 22 can be rotated through the operating block 23 to drive the threaded rod 22 to rotate inside the fixed block 21, and then the threaded rod 22 drives the adjustment plate 24 to move closer to or away from the base 1 to change the overall size of the base 1, and then the pad 25 of other suitable sizes can be reinserted between the base 1 and the adjustment plate 24 for support, and then the arm 4 can grab and move objects at different heights. By using the adjusting device 2 to change the height of the base 1, the arm 4 of the robotic arm can grab and move objects at different heights, thereby improving the adaptability of the robotic arm.
[0030] Reference Figure 1-4As shown, this embodiment discloses that one side of the cushion block 25 is fixedly connected with an auxiliary frame 26, and the cross section of the auxiliary frame 26 is U-shaped. By using the auxiliary block, the contact area between the cushion block 25 and the staff is increased, so that the staff can move the cushion block 25 more easily. The side of the adjustment plate 24 away from the threaded rod 22 is fixedly connected with a rubber pad 27, and the size of the rubber pad 27 is adapted to the size of the adjustment plate 24. By using the rubber pad 27, the friction between the adjustment plate 24 and the ground is increased, so that the stability of the adjustment plate 24 on the ground is improved. An extension plate 28 is fixedly connected to one side of the base 1, and a limit plate 29 is slidably connected inside the extension plate 28, and one side of the limit plate 29 is fixedly connected to the adjustment plate 24. The moving track of the adjustment plate 24 is limited by the limit plate 29 sliding inside the extension plate 28, so as to improve the stability of the movement of the adjustment plate 24.

By using the bearing 210 , the friction between the threaded rod 22 and the adjustment plate 24 is reduced, so that the threaded rod 22 can be more easily rotated on the surface of the adjustment plate 24 .
[0031] Reference Figure 1-4 As shown, the present embodiment discloses that the connection assembly 3 includes a mounting block 31, the mounting block 31 is fixedly connected to the base 1, a bolt 32 is threadedly inserted on one side of the mounting block 31, a connecting plate 33 is threadedly connected on one side of the bolt 32, and one side of the connecting plate 33 is fixedly connected to the arm body 4.

[0032] Reference Figure 1-4 As shown, the present embodiment discloses that guide plates 34 are fixedly connected to both sides of the mounting block 31, and the guide plates 34 are obliquely arranged on both sides of the mounting block 31. By using the guide plates 34, the size of the entrance of the mounting block 31 is increased, so that the connecting plate 33 can be more easily inserted into the interior of the mounting block 31. A plurality of anti-sliding blocks 35 are fixedly connected to one side of the bolt 32, and the plurality of anti-sliding blocks 35 are equidistantly arranged on one side of the bolt 32. By using the anti-sliding blocks 35, the friction between the bolt 32 and the staff is increased, so that the staff can turn the bolt 32 more easily.
[0033] Working principle: When using the robotic arm, the arm body 4 is installed and fixed to the surface of the base 1, and then the arm body 4 is moved away from the side of the base 1 to grab the object, and then the arm body 4 is rotated to move the grabbed object. When changing the height of the base 1 so that the arm 4 can grab and move objects at different heights, the auxiliary frame 26 can be used to move the cushion block 25 so that the cushion block is separated from the base 1 and the adjustment plate 24. Then, the operating block 23 is used to rotate the threaded rod 22 with the bearing 210 so that the threaded rod 22 is driven to rotate inside the fixed block 21. Then, the threaded rod 22 drives the adjustment plate 24 with the rubber pad 27 to approach or move away from the base 1. At this time, the movement trajectory of the adjustment plate 24 is limited by the limit plate 29 sliding inside the extension plate 28. Then, the overall size of the base 1 is changed, and then the cushion blocks 25 of other suitable sizes are reinserted between the base 1 and the adjustment plate 24 for support. Then, the arm 4 can grab and move objects at different heights. By using the adjusting device 2 to change the height of the base 1, the arm 4 of the robotic arm can grab and move objects at different heights, thereby improving the adaptability of the robotic arm.
[0034] When repairing the robotic arm, the bolt 32 with the anti-sliding block 35 can be rotated to disengage the bolt 32 from the connecting plate 33 and the mounting block 31 with the guide plate 34, and then the arm body 4 can be moved to disengage the connecting plate 33 from the mounting block 31, thereby enabling the arm body 4 to be disengaged from the base 1, and then it is convenient for the staff to repair the arm body 4 of the robotic arm. By using the connecting assembly 3, the arm body 4 of the robotic arm can be quickly connected and disassembled with the base 1, thereby facilitating the staff to repair the robotic arm.
