To open the safety cover assembly 1, the user rotates the turret 12 synchronously by rotating the handle 13 and activates the operating circuit by interaction of the activation switch 14 with the turret 12. If the safety cover assembly 1 is in the open state, the user may accidentally rotate the handle 13 to start the working circuit, which may cause the risk of scalding the user by the blank explosion assembly disposed on the safety cover assembly 1, and for this reason, the present invention provides the safety lock mechanism 15 to lock the rotating frame 12 when the safety cover assembly 1 is in the open state, so as to prevent the working circuit from being opened.

Preferably, the safety lock mechanism 15 includes a gravity weight 151, the gravity weight 151 is rotatably disposed on the cover 11, and the gravity weight 151 is disposed with respect to a first rotation axis 152 of the cover 11:
