DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shell shrimp, and more particularly to a shell shrimp body stretcher.

[0002]

[Problems to be solved by the invention] Kitchens of hotels and inns,
Caterers, bento shops, restaurants and the like often offer car shrimp tempura or fried to customers. In this case, the order of cooking is to first shell the shrimp with shells, and then remove the back of the shrimp with a gold or bamboo skewer. At this time, since the shrimp remains in a bent state, it is difficult to remove the back, and the shrimp may be cut off in the middle. If the spine breaks in the middle, extra work and time are required to pull out the rest. The shrimp from which the back is removed is wrapped with a material at a predetermined time and fried on a tempura or fried. By the way, in the case of tempura, if the shrimp is small, the finished product will not look good if it is bent. So, before wrapping the shrimp with the ingredients,
A kitchen knife on the side from which the limbs of the abdominal segment of the shrimp were removed 1 /
The cut is made at an appropriate depth with a depth of 2 to 2/3 and several cuts, and the shrimp are patted lightly with the back of a kitchen knife to extend it. Then, since the bent shrimp grows straight and becomes large, the appearance of the finished tempura product is improved. Also in the case of fry, if the shrimp is small and bent, the amount of the rolls is relatively large compared to the size of the shrimp, so that the taste of the shrimp is lost in the taste of the rolls. Therefore, as in the case of tempura, the bent shrimp is cut and lengthened. By the way, such a cut cannot be done well unless a skilled cook cuts the shrimp by mistake, and the efficiency is not improved.

SUMMARY OF THE INVENTION It is an object of the present invention to solve all of the above-mentioned problems by providing a required number of cuts in a curled shrimp with a scapula and limbs removed, and a stretchable shell shrimp that can be stretched at the same time. To provide a vessel.

Steeper tooth (5) (5b)
Is nearly vertical. It should be noted that car shrimp is used as the type of shrimp.

Both sides of the rear end of the pressing lid (3) are attached to both sides of the rear end of the receiver (2) via a pair of links (6), and the pressing lid (3) is attached to the upper part of the link (6). The pivot (6) is pivotable about the shaft (7), and the link (6) is pivotable about the lower mounting shaft (8), so that the pressing lid (3) is movable back and forth. . The moving state of the pressing lid (3) is indicated by the solid line position in FIG. 1 and three different chain line positions. The rear upper corner of the receiver (2) is formed as an arc-shaped portion (17) so that the pressing lid (3) can move smoothly.

The receptor (2) comprises a center plate (9) and a center plate (9).
And left and right side plates (10) fixed at both sides of the center plate and having a height capable of forming the groove (1), and the upper surface of the center plate (9)
All teeth of the serration (4) are made with a groove bottom having (4)
The line (L) connecting the upper ends of (5) is inclined from the back to the front, and the combination of the height positions of the front end and the rear end of the center plate (9) with respect to the left and right side plates (10) is variable. . That is, a horizontal slot (11) is formed in the lower part near the front end of the left and right side plates (10), and the central plate (9) is formed corresponding to the slot (11).
A long screw hole (12) is drilled forward and a long screw bolt (13) is passed through both long holes (11) and (12), and butterflies are provided at both ends protruding outward from the left and right side plates (10). The nut (14) is threaded. Upper mounting shaft (7) and lower mounting shaft
The same long screw bolt is used for (8), and the long screw bolt, which is the upper mounting shaft (7), is passed through the upper ends of the pressing lid (3) and the pair of links (6). Link
(6) The wing nuts (15) are screwed into both protruding ends. The tightening degree of the wing nut (15) depends on the pressing lid (3).
Is swingable. Lower mounting shaft
