[0045] The brake cavity A132 includes a braking area A133 and a free area A134; the outer wall of the brake cavity A132 in the braking area A133 and the outer wall of the brake cavity A132 in the free area A134 are eccentrically arranged; the outer wall radius of the brake cavity A132 in the braking area A133 is R1, and the outer wall radius of the brake cavity A132 in the free area A134 is R2, and R1 > R2.

The inner cover plate lever A42 and the outer cover plate lever A32 each contact a braking roller A9. A cover plate spring A5 is arranged between the inner cover plate spring seat A41 and the outer cover plate spring seat A31.
[0047] The braking handle A1 is connected to the wire pulling plate A8. One end of the wire pulling plate A8 is connected to the wire A2. The other end of the wire A2 is connected to the outer cover plate A3 and the inner cover plate A4 through the wire locking device A6 and the wire end cap A7. One end of the outer sleeve of the wire A2 abuts against the wire pulling plate A8. The other end of the outer sleeve of the wire A2 abuts against the inner cover plate spring seat A41.

The other end of the inner core of the wire A2 penetrates through the inner cover plate spring seat A41 and the cover plate spring A5, and is connected to the outer cover plate spring seat A31.
[0048] This braking mechanism is used to connect between the clamping bracket A11 and the folding bracket A13, between two folding brackets A13, and between the folding bracket A13 and the bracket base A14. When the braking mechanism is used to connect the clamping bracket A11 and the folding bracket A13, the clamping bracket rotating shaft A111 of the clamping bracket A11 is installed on the braking disc A131 of the folding bracket A13 through the spline seat A10. When the braking mechanism is used to connect two folding brackets A13, the folding bracket rotating shaft A135 of one folding bracket A13 is installed on the braking disc A131 of the other folding bracket A13 through the spline seat A10. When the braking mechanism is used to connect the folding bracket A13 and the bracket base A14, the folding bracket rotating shaft A135 of the folding bracket A13 is installed on the bracket braking disc of the bracket base A14 through the spline seat A10, and the inner wall of the braking cavity A132 is arranged on the outside of the spline seat A10.
[0049] The robotic arm bracket B includes a locking pin B1, a guide rail baffle B2, a bench fixture B3, a bench B4, bench feet B5 and a sliding guide rail B6. The sliding guide rail B6 is arranged on the top of the bench B4. Each end of the sliding guide rail B6 is provided with a guide rail baffle B2. One of the guide rail baffles B2 is fixedly arranged, and the other guide rail baffle B2 is installed through the locking pin B1. The bench fixture B3 and the bench feet B5 are respectively arranged on both sides of the bench B4. The robotic arm A is installed on the sliding guide rail B6. The bench B4 is installed on the working bucket C through the bench fixture B3 and the bench feet B5.
[0050] The working method of the aerial work auxiliary robotic arm is as follows: By controlling the opening size of the clamping bracket A11 through the clamping knob A16, it can adapt to clamping work tools of different sizes; When the sliding and rotating handle A15 is in the braking state, the robotic arm A is fixed within the sliding guide rail B6 and cannot slide or rotate; When the sliding and rotating handle A15 is in the free state, the robotic arm A can slide and rotate within the sliding guide rail B6; The robotic arm A can adjust its posture through the braking mechanism to adjust the work tool to the working position.
[0051] The process of controlling the robotic arm A through the braking mechanism is as follows: When the brake handle A1 is in the free state, the cover plate spring A5 and the brake spring A12 are in the stretched state. At this time, the brake roller A9 is subjected to the pressure of the brake spring A12, and the brake spring A12 springs the two brake rollers A9 into the braking area A133, causing the brake roller A9 to contact the inner and outer walls of the brake cavity A132 and generating relative friction, thereby making the spline seat A10 and the brake disc A131 in the braking state and unable to rotate.
[0052] When the brake handle A1 is gripped tightly, the wire A2 drives the inner cover plate A4 to rotate counterclockwise and the outer cover plate A3 to rotate clockwise, causing the cover plate spring A5 to be in a compressed state. At the same time, the two brake rollers A9 are respectively toggled through the inner cover plate lever A42 and the outer cover plate lever A32, thereby also causing the brake spring A12 to be in a compressed state, making the brake roller A9 toggle into the free area A134. The brake roller A9 is in a non-contact state with the inner and outer walls of the brake cavity A132, thereby making the spline seat A10 and the brake disc A131 in the free state and able to rotate.
[0053] Specifically, when the sliding and rotating handle A15 is opened, at this time the robotic arm A can freely rotate around the center point of the support base A14, and the robotic arm A can freely move within the sliding guide rail B6. When the sliding and rotating handle A15 is closed, the relative position of the robotic arm A and the robotic arm support B is fixed. By rotating the clamping knob A16 to adjust the opening size of the clamping bracket A11, work tools of different sizes can be clamped.
[0054] When the brake handle A1 is gripped tightly, the wire A2 drives the inner cover plate A4 to rotate counterclockwise and the outer cover plate A3 to rotate clockwise. At this time, the cover plate spring A5 is squeezed by the inner cover plate spring seat A41 and the outer cover plate spring seat A31, and the brake spring A12 is squeezed by the inner cover plate lever A42 and the outer cover plate lever A32 and is in a compressed state; When the brake handle 1 is released and the brake handle A1 is in the free state, the inner cover plate A4 and the outer cover plate A3 are reset under the spring force of the cover plate spring A5 and the brake spring A12.
[0055] The guy wire plate A8 can be connected to multiple guy wires A2 to achieve synchronous opening and synchronous braking of multiple joints. The braking mechanism can ensure that the robotic arm joint is in a rotatable state by gripping the brake handle A1; when the brake handle A1 is released, the robotic arm joint is ensured to be in a locked state.
