Wherein, a cavity 1212 communicated with the opening is arranged in the box body 121, and the cavity 1212 is filled with insulating oil. The upper cover plate 123 is bolted to the case 121 while sealing the film 122 to the opening of the case 121. The push rod assembly 140 is disposed in the cavity 1212, and the push rod assembly 140 is a motor screw rod structure. The actuating assembly 130 includes a catch 131 located outside the cavity 1212, and an actuating shaft 132 drivingly connecting the catch 131 and the push rod assembly 140. In addition, the case assembly 120 further includes a wire assembly disposed in the case 121 and electrically connected to the push rod assembly 140, which belongs to the prior art and is not described herein again. It should be noted that, in another embodiment, the push rod assembly 140 may be a mechanism in the prior art, in which the output end may move back and forth, such as a mechanism composed of a motor, a gear and a rack, and the details are not repeated herein.
In operation, the push rod assembly 140 can drive the catch 131 to move back and forth through the actuating shaft 132.

Meanwhile, the insulating oil can have good thermal conductivity, so that heat generated by the push rod assembly 140 and other parts during working is conducted out, and the working reliability of the trigger safety mechanism 100 is further improved. In addition, the film 122 has elasticity, which can further ensure the balance of the external pressure in the cavity 1212.
As shown in fig. 1 and fig. 2, the present embodiment further provides a deep sea sampler, which includes a trigger mechanism 200 and a trigger safety mechanism 100, wherein the trigger mechanism 200 has a switch core shaft 210, and the trigger safety mechanism 100 is mounted on the deep sea sampler through a mounting base 110. In actual operation, during the process of lowering the sampler, the push rod assembly 140 drives the clip 131 to move to the switch core shaft 210, so that the trigger mechanism 200 will not be triggered under complicated sea conditions. It should be noted that the trigger mechanism 200 including the switch core shaft 210 belongs to the existing device in the art, and is not described herein again.
In the actual working process, the deep sea sampler of the present embodiment is configured with the triggering safety mechanism 100 of the present embodiment, so that the triggering mechanism 200 is prevented from being triggered in advance due to the complex sea conditions such as waves during the lowering process of the sampler. The deep sea sampler that significantly reduces leads to the sample failure because of the frequent mistake of trigger mechanism 200 touches, greatly improves the efficiency of sample operation.
