Problems solved by technology
[0006] In order to solve the above-mentioned technical problems, the present invention provides a medical mask flame retardant test device used in laboratories to solve the problem that the existing flame retardant test equipment has a poor dynamic simulation effect of wearing a mask, and the test method for burning in front of a fire is not reasonable enough. As a result, the accuracy of the flame retardant test is poor, and the flame retardant performance of the medical mask cannot be well reflected, and the optimal design of the clamping and fixing structure of the mask is not reasonable enough, and it cannot be well clamped and positioned for various length specifications. The replacement operation of the mask is also relatively inconvenient
