Six-degree-of-freedom joint type mechanical arm

The six-degree-of-freedom joint type mechanical arm comprises a first shaft seat, a second shaft seat, a third shaft arm rod, a fourth shaft arm rod, a fifth shaft arm rod and a claw which are sequentially connected, a first joint is arranged between the second shaft seat and the third shaft arm rod, a second joint is arranged between the third shaft arm rod and the fourth shaft arm rod, and a third joint is arranged between the fourth shaft arm rod and the fifth shaft arm rod. Elastic clamping plate structures are arranged on the two sides of the five-axis arm rod. The three-axis arm lever comprises a first arm lever and a second arm lever; the axial directions of the first arm lever and the second arm lever are consistent and the first arm lever and the second arm lever are rotationally connected with each other through a first rotating shaft; and through mutual cooperation of the first rotary clamping and reinforcing assembly, the second rotary clamping and reinforcing assembly and the third rotary clampin
