The brake chamber 132 includes a braking area 133 and a free area 134.

[0032] The outer wall of the brake chamber 132 in the brake area 133 and the outer wall of the brake chamber 132 in the free area 134 are eccentrically arranged, the outer wall radius of the brake chamber 132 in the brake area 133 is R1, and the outer wall radius of the brake chamber 132 in the free area 134 is R2, R1>R2.

[0033] An inner cover plate spring seat 41, an inner cover plate lever 42 and an inner cover plate lever hole 43 are provided on the inner cover plate 4, an outer cover plate spring seat 31 and an outer cover plate lever 32 are provided on the outer cover plate 3, a cover plate spring 5 is provided between the inner cover plate spring seat 41 and the outer cover plate spring seat 31, the outer cover plate lever 32 and the inner cover plate lever hole 43 penetrate, the inner cover plate lever 42 and the outer cover plate lever 32 are both located in the brake chamber 132, and the inner cover plate lever 42 and the outer cover plate lever 32 are respectively in contact with a brake roller 9.

[0034] The brake handle 1 is connected to the pull wire plate 8, the pull wire plate 8 is connected to one end of the pull wire 2, the other end of the pull wire 2 is connected to the outer cover plate 3 and the inner cover plate 4 through the wire locker 6 and the wire tail cap 7, one end of the outer jacket of the pull wire 2 abuts against the pull wire plate 8, the other end of the outer jacket of the pull wire 2 abuts against the inner cover spring seat 41, one end of the inner core of the pull wire 2 is connected to the pull wire plate 8, the other end of the inner core of the pull wire 2 passes through the inner cover spring seat 41 and the cover spring 5, and is connected to the outer cover spring seat 31.

[0035] The braking mechanism is used to connect the clamping bracket 11 with the folding bracket 13, or two folding brackets 13, or the folding bracket 13 with the bracket base 14. When the braking mechanism is used to connect the clamping bracket 11 with the folding bracket 13, the clamping bracket rotating shaft 111 of the clamping bracket 11 is installed on the brake disc 131 of the folding bracket 13 through the spline seat 10; when the braking mechanism is used to connect two folding brackets 13, the folding bracket rotating shaft 135 of one folding bracket 13 is installed on the brake disc 131 of the other folding bracket 13 through the spline seat 10; when the braking mechanism is used to connect the folding bracket 13 with the bracket base 14, the folding bracket rotating shaft 135 of the folding bracket 13 is installed on the bracket brake disc of the bracket base 14 through the spline seat 10, and the inner wall of the brake cavity 132 is arranged on the outer side of the spline seat 10.

[0036] Specifically, when the braking mechanism is working, when the brake handle 1 is in a free state, the cover spring 5 and the brake spring 12 are in a stretched state. At this time, the brake roller 9 is subjected to the pressure of the brake spring 12, and the brake spring 12 bounces the two brake rollers 9 into the braking area 133, so that the brake roller 9 contacts the inner wall and outer wall of the brake cavity 132 and generates relative friction, thereby making the spline seat 10 and the brake disc 131 in a braking state and unable to rotate.

[0037] When the brake handle 1 is gripped, the pull wire 2 drives the inner cover plate 4 to rotate counterclockwise and the outer cover plate 3 to rotate clockwise, so that the cover plate spring 5 is in a compressed state. At the same time, the two brake rollers 9 are respectively pushed through the inner cover plate lever 42 and the outer cover plate lever 32, so that the brake spring 12 is also in a compressed state, so that the brake roller 9 is pushed into the free area 134, and the brake roller 9 is in a non-contact state with the inner and outer walls of the brake chamber 132, so that the spline seat 10 and the brake disc 131 are in a free state and can rotate.

[0038] When the brake handle 1 is gripped, the pull wire 2 drives the inner cover 4 to rotate counterclockwise and the outer cover 3 to rotate clockwise. At this time, the cover spring 5 is squeezed by the inner cover spring seat 41 and the outer cover spring seat 31, and the brake spring 12 is squeezed by the inner cover lever 42 and the outer cover lever 32 and is in a compressed state; when the brake handle 1 is released and the brake handle 1 is in a free state, the inner cover 4 and the outer cover 3 are reset by the spring force of the cover spring 5 and the brake spring 12.

[0039] The pull wire plate 8 can be connected to multiple pull wires 2 to achieve synchronous opening and synchronous braking of multiple joints. The braking mechanism can ensure that the mechanical arm joint is in a rotatable state by holding the brake handle 1; when the brake handle 1 is released, the mechanical arm joint is ensured to be in a locked state.
