The invention relates to an extrusion containing type fishing net collecting and tightening device. The extrusion containing type fishing net collecting and tightening device comprises a bottom plate. A curve-shaped track plate is fixed to the bottom plate, and a C-shaped containing groove is formed in the upper end of the track plate. The part, located at the opening position of the C-shaped containing groove, of the track plate is provided with a roll shaft arranged on the bottom plate and connected with a first motor, and a baffle is hinged to the right side of the C-shaped containing groove. The C-shaped containing groove is provided with a groove. A tightening device penetrating the groove for tightening and fixed to the bottom plate is arranged at the right end of the track plate and comprises a fixed support, a first clamping hand, a second motor, a movable support and a second clamping hand. The extrusion containing type fishing net collecting and tightening device has the beneficial effects that the functions of collecting and tightening can be achieved, fishing net knotting and wrinkling can be avoided, fishing net damage due to dragging force generated in the fishing net collecting process can be avoided, and the service life of a fishing net is guaranteed; and the fishing net collecting permeability is good, airing is convenient, and the extrusion containing type fishing net collecting and tightening device is suitable for large-scale usage and popularization.
