A safety catch device of a sealing machine has a baffle and a probe set. The baffle is pivotally arranged at the opening of the machine body. A conducting sheet is provided at the rear side of the baffle. The probe set has a first probe and a second probe, which are connected to a circuit unit with signal cables. The front end of the first probe exceeds the front end of the second probe by a certain distance. The front end of the first probe contacts the conducting sheet. The front end of the second probe keeps a certain distance from the conducting sheet. When the baffle swings backwards, the conducting sheet contacts the front end of the second probe to transfer signals to the circuit unit for stopping the film sealing operation. The safety of operation can thus be greatly enhanced to effectively avoid occurrence of hazards.
