The top end of the return spring is connected with a clamping plate, and a clamping rod is fixed on the other side of the clamping plate. Card slots for the clamping rod to penetrate and be limited are opened on both sides of the connecting and mounting strip blocks. Guide rods for guiding the movement of the clamping plate are fixed on the upper and lower sides inside the side mounting openings.
[0007] Further, both sides of the upper end of the placement groove formed inside the lower clamping part are distributed in an outward-expanded ladder shape.
[0008] Furthermore, the space between the two connected mounting strips fixed inside the upper clamping part is distributed in a ladder shape, and the relative outward-expansion distance of the two connected mounting strips is smaller than the outward-expansion angle of the upper end of the placement groove.
[0009] Furthermore, the lower clamping part and the upper clamping part form a deformable connection through an elastic rubber connecting piece.
[0010] Furthermore, the fixing strip is distributed in an inclined shape, and the inner angle of the fixing strip matches the preset inclined surface angles of both sides of the lower clamping part.
[0011] Furthermore, the guide rods are symmetrically fixed on both sides inside the side mounting opening, and the length of the guide rods is the same as the length of the reset spring when it is not energized.
[0012] (3) Beneficial effects
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] The personnel of the present utility model first place the crayfish to be peeled in the placement groove inside the lower clamping part, with the shrimp body on top. Then, by using the deformability of the elastic rubber connecting piece, the upper clamping part is manually flipped by a certain angle, so that the positions of the two connected mounting strips inside the upper clamping part and the serrated frame installed therein can be relative to the shrimp body part of the crayfish placed inside the placement groove. Then, continue to apply more force to squeeze. At this time, the two serrated frames can saw-press along both sides of the shrimp shell to achieve the effect of separating the shell from the meat. Since the serrated frame moves downward with the upper clamping part, the fixing strips on both sides inside the upper clamping part will just fit and press on the inclined surfaces on both sides inside the lower clamping part, so as to ensure that the two clamping parts will not be misaligned with each other, thereby avoiding the phenomenon of uneven meat peeling caused by the separation and offset of the crayfish. After the squeezing and separation are completed, the serrated frame will rebound and retract from the back of the crayfish through the elastic rubber connecting piece. The user can slowly open the space between the lower clamping part and the upper clamping part with the ear to take the corresponding lobster meat.
[0015] Since the serrations distributed at the end of the serrated frame of the present utility model are formed by plastic mold opening, when the personnel place the crayfish in the wrong position with the carapace facing up or the whole lobster claw falls to the ground for the first time, due to the small contact surface of the serrations, it is easy to cause the fracture and loss of some plastic serrations. If the whole lobster claw is replaced, the cost is relatively high. At this time, the personnel pinch the clamping rods protruding from the card slots on both sides of the connected mounting strip, so that the clamping plate is pressed and the reset spring is energized inside the side mounting opening of the connected mounting strip, so that the clamping rods can be completely retracted into the side mounting opening. At this time, the damaged serrated frame can be removed and replaced with the same components, which is portable and practical while reducing costs. Brief Description of the Drawings

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] This specific embodiment is a lobster clamp, and its structural schematic diagram is as Figures 1 to 4As shown in the figure, it includes a lower clamping part 1. In the middle of one side of the lower clamping part 1, an elastic rubber connecting piece 2 is connected. And on the other side of the elastic rubber connecting piece 2, an upper clamping part 3 is connected. A deformable connection is formed between the lower clamping part 1 and the upper clamping part 3 through the elastic rubber connecting piece 2. On one side of the inner side of the lower clamping part 1, a placement groove 4 is opened. The two sides at the upper end of the placement groove 4 opened on the inner side of the lower clamping part 1 are distributed in an outward-expanded trapezoidal shape. Horizontally on one side of the inner side of the upper clamping part 3, two connected strip blocks 5 are fixed. The two connected strip blocks 5 fixed on the inner side of the upper clamping part 3 are distributed in a trapezoidal shape. And the relative outward-expanded distance between the two connected strip blocks 5 is smaller than the outward-expanded angle at the upper end of the placement groove 4. Vertically on both sides of the inner side of the upper clamping part 3, fixed strips 7 are fixed. The fixed strips 7 are distributed in an inclined shape. And the inner angle of the fixed strips 7 matches the preset inclined surface angles on both sides of the lower clamping part 1. And at one end of the upper clamping part 3, an ear 8 is fixed. In the middle of the two connected strip blocks 5, a to-be-installed groove 9 is preset. And inside the to-be-installed groove 9, a serrated frame 6 is embedded. In the middle of both sides of the serrated frame 6, side installation ports 10 are opened. And in the middle of the side installation ports 10, a return spring 11 is fixed. The top end of the return spring 11 is connected to a clamping plate 12. And on the other side of the clamping plate 12, a clamping rod 13 is fixed. On both sides of the connected strip blocks 5, clamping grooves 14 for the clamping rod 13 to penetrate and be limited are opened. On the upper and lower sides inside the side installation ports 10, guide rods 15 for guiding the movement of the clamping plate 12 are fixed. The guide rods 15 are symmetrically fixed on both sides inside the side installation ports 10. And the length of the guide rods 15 is the same as the length of the return spring 11 when it is not energized. Personnel first place the crayfish to be peeled in the placement groove 4 on the inner side of the lower clamping part 1, with the shrimp body on top. Then, using the deformability of the elastic rubber connecting piece 2, manually flip the upper clamping part 3 by a certain angle so that the positions of the two connected strip blocks 5 on the inner side of the upper clamping part 3 and the serrated frame 6 installed inside them can be relative to the shrimp body part placed in the placement groove 4. Then continue to apply force to squeeze. At this time, the two serrated frames 6 can saw-press along both sides of the shrimp shell to achieve the effect of separating the shell from the meat. Since when the serrated frame 6 is pressed down with the upper clamping part 3, the fixed strips 7 on both sides of the inner side of the upper clamping part 3 will just fit and press on the inclined surfaces on both sides of the inner side of the lower clamping part 1, so as to ensure that the two clamping parts will not be misaligned with each other, thereby avoiding the phenomenon of uneven meat peeling caused by the separation and offset of the crayfish. After the squeezing and separation are completed, the serrated frame 6 will rebound and retract from the back of the crayfish through the elastic rubber connecting piece 2. The user can slowly open the space between the lower clamping part 1 and the upper clamping part 3 with the ear 8 to take the corresponding lobster meat. It is worth mentioning that since the serrations distributed at the end of the serrated frame 6 are plastic-molded, when personnel put the crayfish in the wrong position with the carapace facing up or the whole lobster claw falls to the ground for the first time, because the contact surface of the serrations is small, it is easy to cause the fracture and loss of some plastic serrations. If the whole lobster claw is replaced, the cost is relatively high. At this time, personnel pinch the clamping rods 13 protruding from the clamping grooves 14 on both sides of the connected strip blocks 5, so that the clamping plate 12 is pressed to energize the return spring 11 in the side installation port 10 inside the connected strip blocks 5, so that the clamping rod 13 can be completely retracted into the side installation port 10.At this moment, the operator can remove the damaged sawtooth rack 6 and replace it with the same component, which is portable and practical while reducing costs.
[0024] Working principle: The operator places the crayfish to be peeled in the placement groove 4 inside the lower clamping part 1 in advance, with the shrimp body on top. Then, using the deformability of the elastic rubber connecting piece 2, the operator manually flips the upper clamping part 3 by a certain angle so that the positions of the two connected strip blocks 5 on the inner side of the upper clamping part 3 and the sawtooth rack 6 installed inside them can be relative to the shrimp body part placed in the placement groove 4. Then, continue to apply more force to squeeze. At this moment, the two sawtooth racks 6 can saw-press along both sides of the shrimp shell to achieve the effect of separating the shell from the meat. Since the sawtooth rack 6 moves downward with the upper clamping part 3, the fixed strips 7 on both inner sides of the upper clamping part 3 will just fit and press on the inclined surfaces on both inner sides of the lower clamping part 1, thus ensuring that the two clamping parts do not misalign with each other, and avoiding the phenomenon of uneven meat peeling caused by the separation and offset of the crayfish. After the squeezing and separation are completed, the sawtooth rack 6 will rebound and retract from the back of the crayfish through the elastic rubber connecting piece 2. The user can gently open the space between the lower clamping part 1 and the upper clamping part 3 with the ear 8 to take the corresponding lobster meat. It is worth mentioning that since the sawteeth distributed at the end of the sawtooth rack 6 are made by plastic molding, when the operator misplaces the crayfish with its carapace facing up or the whole lobster claw falls to the ground for the first time, due to the small contact surface of the sawteeth, it is easy to cause the fracture and loss of some plastic sawteeth. If the whole lobster claw is replaced, the cost is relatively high. At this moment, the operator pinches the clamping rods 13 protruding from the card slots 14 on both sides of the connected strip block 5, so that the clamping plate 12 is pressed and the return spring 11 is energized in the side mounting port 10 inside the connected strip block 5, so that the clamping rods 13 can be fully retracted into the side mounting port 10. At this moment, the operator can remove the damaged sawtooth rack 6 and replace it with the same component, which is portable and practical while reducing costs.
[0025] All technical features in this embodiment can be freely combined according to actual needs.
