The application relates to the technical field of grabbing structures, in particular to an
underwater target grabbing device, which comprises a grabbing
assembly, a main frame, a positioning
assembly and a mounting interface, the grabbing
assembly is used for realizing a grabbing action; the grabbing assembly is installed on a grabbing end of the main frame; the positioning assembly is installed on a positioning end of the main frame; the mounting interface is installed on an end of the positioning assembly which is far away from the main frame; the grabbing assembly comprises a support frame, two grabbing rods, anti-skid blocks and a rotating shaft, the rotating shaft is rotatably arranged in the support frame, one end of each of the two grabbing rods is rotatably connected with the rotating shaft, one grabbing rod is located above the other grabbing rod, the other end of each of the two grabbing rods is hingedly provided with an anti-skid block, the grabbing rod located above is connected with the support frame through a torsional spring, and the grabbing rod located below is connected with the support frame through a first tensile spring. The grabbing assembly of the application can realize the grabbing action by touching the target through the contact of the pushing rod, and the torsional spring and the first tensile spring are used to drive the grabbing rod to realize the grabbing action.
