[0027] As Figures 1-5As shown, the end of the pin 16 is fixedly connected with a fixed sheet 2; the middle of the fixed sheet 2 is provided with two groups of top blocks 21, and the top blocks 21 are provided in a circular arc shape; the inside of the top block 21 is provided with a receiving groove 22; the middle of the fixed sheet 2 is fixedly connected with two groups of second spring rods 23, and the other end of the second spring rod 23 is fixedly connected to the inner wall of the receiving groove 22; during operation, the fixed sheet 2 is provided at the end of the pin 16, and the two groups of top blocks 21 can be opened outward under the action of the elasticity of the two groups of second spring rods 23, and during the closing process between the pin 16 and the inner groove 17, the two groups of top blocks 21 in a circular arc shape will directly contact the inner wall of the inner groove 17 and extrude the two groups of top blocks 21, until the two groups of top blocks 21 are close to and assembled into a semicircular shape, and the second spring rod 23 is expanded outwardly, so that the two groups of top blocks 21 can be in contact with the inner wall of the inner groove 17, and the two groups of top blocks 21 provided in this step can improve the stability of the contact between the inner groove 17 and the pin 16, and reduce the shaking of the mixing head main body 1 during subsequent operation. Because there is a gap between the pin 16 and the inner groove 17, the problem of frequent impact and contact between them exists.
