Eel bone removing knife

Abstract

The invention relates to the technical field of eel bone removal, in particular to an eel bone removal knife. An eel boning knife, comprising: a handle and two blades that are symmetrical about the central axis where the handle is located, the handle is connected to the blades through a distance adjustment device, and the distance adjustment device includes: a support seat, the support seat It includes: an outer frame and an inner frame, the outer frame and the inner frame are connected through a rack, a screw, one end of the screw is fixedly connected with the knife handle, and the other end passes through the support seat and is rotatably connected with it, two slides The sliders are distributed symmetrically along the straight line where the screw is located. The sliders are slidably connected to the support base. The distance between the two sliders along the direction of screw extension decreases. The blade is sandwiched between the slider and the support seat. between supports. The invention provides an eel deboning knife, which solves the problem that eels of different body sizes cannot be adjusted for deboning, and improves the work efficiency of eel deboning.

Description

technical field [0001] The present invention relates to the technical field of eel deboning, in particular to an eel deboning knife. Background technique [0002] Some long-shaped fish, such as eels, have much higher nutritional content than chicken, beef, etc., and the content of vitamins, minerals and trace elements is unmatched by terrestrial animals. Scientific research shows that eel is one of the fish with the highest EPA and DHA, which can not only reduce blood lipids, resist arteriosclerosis, resist thrombosis, but also supplement the necessary nutrients for the brain. [0003] Nowadays, the demand for eating eels is increasing. Chinese patent CN201410718503.2 discloses a long-shaped fish slaughtering and deboning knife. You only need to hold the eel with one hand first, and then use the other hand to slaughter the eel. The blade A of the present invention is inserted from the front end of the spine of the eel, and the blade B is squeezed tightly, and the blade B is...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that eels of different sizes cannot be adjusted and deboned, the present invention provides an eel deboning knife. When in use, first adjust the outer frame and inner frame through the rack In order to adjust the distance between the two blades to suit different widths of eel bones, insert the two blades into the abdomen or back of the eel from both sides of the eel bone, and insert the two blades into the slider and the eel respectively. Between the outer frame and the slider and the inner frame, the two blades are clamped by tightening the screw to push the slider, hold the knife handle with your hand and pull it towards the fish tail, so as to complete the bone removal work, compared with manual operation Easier bone removal improves work efficiency
