Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1 to Fig. 7, the utility model relates to a kind of ROV friendly fast shackle trippers, including shackle main body
1, main pin 5, spring 6, fixed lateral pin 2 and limit bolt 3, the shackle main body 1 are arranged in headset shape, the main pin 5
Two ears (the first ear 11 and the second ear 12) that one end passes through shackle main body 1 are inserted into a fixed lateral pin 2, the fixation lateral pin afterwards
2 are vertically arranged with main pin 5, and the limit bolt 3 is arranged along the axial direction of main pin, and the limit bolt 3 is by main pin 5 and admittedly
Determine lateral pin 2 to link together；Described 6 sets of spring are on the axis 52 of main pin 5, one end of the spring 6 and the head of main pin
51 weld together, and the other end is located at the outside of the first ear 11 of shackle main body, and moves cooperation with first ear 11.
