Technical Field

[0001] The present invention relates to the field of shrimp shell peeling equipment, and in particular to a manual shrimp peeler. Background Art

[0002] Currently, when peeling shrimp to obtain shrimp meat, it is all done by hand and mouth to peel the shrimp shell. For example, the shell of crayfish is relatively hard. After a long time of shelling, it is inevitable that the hands or mouth will feel pain, swelling or even injury due to contact and friction with the hard shrimp shell. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to solve the technical problems described in the background art, the present invention provides a manual shrimp peeler, which can quickly peel shrimp meat.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a manual shrimp peeler, which includes a main body handle, a movable handle, a shell pressing piece for pressing the shrimp shells on both sides of the shrimp tail, a scraper for scraping shrimp meat, a driving link, a driven link, and elastic members including a tension spring and a torsion spring. The shell pressing piece, the scraper, the driving link, and the movable handle are all provided with through holes and are rotatably hinged to the corresponding through holes on the main body handle through hinge shafts. The movable handle is provided with a through hole and is rotatably hinged to the main body handle by a hinge shaft. Hold the main body handle and apply pressure to the rear part of the movable handle. One end of the movable handle pushes the driving link. After the driving link is pushed, the driven link hinged to the driving link is stressed and pushes the scraper and the shell pressing piece rotatably hinged inside the main body handle to rotate in an orderly manner to form a state of peeling shrimp meat.

[0005] Further, the movable handle is hinged to the main body handle. Apply pressure to the movable handle. The movable handle toggles the driving link rotatably hinged inside the main body handle to rotate. When the driving link rotates, it drives the driven link hinged to one end of the driving link to start moving.

[0006] Further, both ends of the driven link are respectively hinged to the driving link and the scraper. When the driven link is stressed and moves, it applies pressure to the scraper rotatably hinged inside the main body handle. The scraper simultaneously drives the shell pressing piece to rotate around the hinged position of the main body handle.

[0007] Further, the main body handle is provided with a limit boss, so that the shell pressing piece stops rotating after rotating to the limit boss.

[0008] Further, the scraper is inside the shell pressing piece. An elastic member is provided between the scraper and the shell pressing piece. When the scraper rotates, it simultaneously drives the shell pressing piece. After the shell pressing piece rotates to the limit position, it stops moving. The scraper continues to rotate and scrapes out the shrimp meat in the shell pressing piece.

[0009] Further, the elastic member is a torsion spring, which is placed at the hinge between the pressing shell piece and the scraper and the main body handle. One end of the torsion spring presses against the pressing shell piece, and the other end presses against the scraper, pressing the scraper inside the pressing shell piece. When the driven connecting rod pushes the scraper to rotate, the pressing shell piece rotates simultaneously. First, the pressing shell piece rotates to press against the shrimp shells on both sides of the shrimp tail and is limited by the limiting boss of the main body handle. Then, the scraper inside the pressing shell piece rotates to scrape out the shrimp meat.

[0010] Further, a shrimp blocking plate is provided at the front part of the main body handle. The shrimp blocking plate is provided with a curvature to cooperate with the rotation of the pressing shell piece to press the shrimp shells on both sides of the shrimp tail.

[0011] Further, through holes are provided on the main body handle, and hinge shafts are arranged through the through holes to position the movable handle, the driving connecting rod, the pressing shell piece, and the scraper inside the main body handle.

[0012] Such a structure is both labor-saving and compact. Description of the Drawings
