[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point-to-point. According to the purpose, the power cord can be divided into AC power cord and DC power cord. Usually, AC power cord is a wire that transmits high-voltage alternating current. Due to the high voltage, this type of wire needs to obtain safety certification according to unified standards before it can be officially produced. The commonly used transmission conductors inside are copper and aluminum metal wires. Plugs generally refer to the connectors of general electronic products and the plugs of electrical appliances. Plug power cords connect plugs and power cords and are used together to connect electrical appliances and power sources.

[0003] In order to ensure the safety of the use of plug power cords, functional plug power cords such as high temperature resistance and flame retardancy have gradually been developed. The high temperature resistant material and the flame retardant are mixed with each other to form a sheath to wrap the conductor. However, the mixing of the high temperature resistant material and the flame retardant in the prior art is not sufficient and comprehensive, and the use effect is poor. Summary of the invention

After the cooling ball contacts the deformation memory capsule, the temperature is reduced to restore it to its initial state, so that the first magnet block is in a magnetic shielding state, prompting the sliding sleeve to move downward, and realizing driving the sliding sleeve and the stirring ball rod to move up and down, so that the materials are fully mixed. At the same time, the liquid storage frame moves back and forth under the rotating centrifugal force and the attraction of the first magnet block to the magnetic fluid, so that the blowing tube blows back and forth, and cooperates with the squeezing ball to continuously squeeze and impact the hemisphere to impact the blowing tube to generate vibration, so that the residual material falls off, thereby improving the material utilization rate.
