[0008] Furthermore, the angle adjustment assembly includes a base, a limit block, a limit rod and a return spring; the lower end of the base is arc-shaped; the limit block is embedded in the base and can be taken out upward; the two ends of the limit rod pass through the side surfaces of the limit block and the base in turn and the ends of the two sides of the limit rod are respectively embedded in the sliding grooves of the outer plate and the inner plate, and the limit rod is used to limit the sliding and upward removal of the limit block; the two ends of the return spring are respectively fixedly connected to the lower end of the limit block and the bottom surface inside the base.
[0009] Furthermore, the sliding slot is formed into a plurality of continuously arranged grooves on one side of the outer edge of the outer plate and the inner plate, and the limit block is pushed upward by the reset spring to embed the two ends of the limit rod into the grooves.
[0010] Furthermore, a plurality of fixing holes are symmetrically provided on the fixing protrusion, and the support on one side of the upper arm is fixedly connected to the connecting device through bolts and the fixing holes.
[0011] Furthermore, an angle ruler corresponding to the sliding groove is provided on the outer circumference of the outer plate.
[0012] Furthermore, a triangular through hole is provided on the limit block at the outer edge of the outer plate, and the scale of the angle ruler on the outer plate pointed to by the through hole is the sliding angle range of the forearm on the corresponding sliding groove at this time.
[0013] Furthermore, the sliding groove is made of metal.
[0014] Furthermore, a pushing block is convexly provided on the outer side surface of the slider, and the slider and the sliding rod are driven to slide by pushing the pushing block.
