HMI fixing buckle

The utility model discloses an HMI fixing buckle which comprises a buckle body, an elastic mechanism and a clamping hook assembly used for fixedly installing an HMI panel, wherein the buckle body andthe elastic mechanism are communicated up and down. One side of the clamping hook assembly is arranged in the buckle body, and the other side of the clamping hook assembly is located outside the buckle body. The elastic mechanism can be inserted into the buckle main body in a relatively sliding manner; a plurality of first clamping tables and a plurality of second clamping tables are further sequentially arranged on the inner wall of the buckle body, and the elastic mechanism can move upwards to be clamped on the first clamping tables. A plurality of reset mechanisms are arranged on the side face of the buckle body and located above the second clamping tables, so that when the reset mechanisms abut against the elastic mechanisms, the elastic mechanisms are separated from the first clampingtables and slide downward
