Benefits of technology

[0013] 1. The portable fish egg and dead egg separator of this utility model allows for the following operation when adsorbing fish eggs in water: The thumb is placed inside the thumb plate, and two or three of the other four fingers are placed inside the grip groove for hand operation. For delicate operation, one hand can hold the device with its open side, allowing the locking block to fully enter the second groove. The other hand can then slowly move the device upwards by pinching the cover plate, controlling the rise of the column. Dead eggs are then adsorbed through the suction tube. For rough operation (where delicate operation is not required), a single hand can be used, with the four fingers repeatedly opening and gripping the device. When the tube opens, the column moves upward under the action of the spring, causing the piston to move upward as well. During the adsorption of dead eggs, liquid is also drawn in. At this time, the spring adsorption is subject to a certain damping force, which ensures that the overall upward movement distance of the column is limited during the opening and gripping operations, thus ensuring the upward movement of the piston and completing a single adsorption operation. Because there are multiple sets, multiple adsorption operations can be guaranteed. After adsorption is completed, the tube is removed, and then four fingers are spread open and the column is pressed down, causing the piston to move down and thus completing the expulsion of the adsorbed dead eggs. The locking block and positioning block are used to limit the column and complete the fixation operation, making it convenient to carry and use. Because it is an adsorption operation, damage to live eggs can be reduced.

However, due to the inherent characteristics of tweezers, live eggs can be easily damaged if not handled properly, and the removal efficiency of dead eggs is low. Therefore, this invention uses a tube to suck out the dead eggs, reducing the risk of mishandling live eggs. Thus, this utility model provides a portable fish egg and dead egg separator.

[0026] In the prior art, tweezers are generally used to remove dead fish eggs when separating them. However, due to the inherent characteristics of tweezers, live eggs can be easily damaged if not handled properly, and the removal efficiency of dead eggs is low. Therefore, this invention uses a tube 1 to suck out the dead eggs, reducing the risk of mishandling live eggs.

[0027] The piston component includes a column 2; a cover plate 21 is fixedly connected to the top of the column 2; the diameter of the cover plate 21 is smaller than the inner diameter of the tube 1; a first groove 22 is provided at the bottom of the column 2; the first groove 22 is circular; a second annular groove 23 is provided on the inner wall of the first groove 22; a first connecting post 24 is fixedly connected to the middle of the bottom of the first groove 22; the rigid tube 17 is located in the first groove 22, and the first connecting post 24 is located in the rigid tube 17; a piston 25 is fixedly connected to the bottom of the first connecting post 24, and the piston 25 is slidably connected to the inner wall of the rigid tube 17; a first spring 26 is placed in the first annular groove 15, and the bottom of the first spring 26 is placed on the top of the rotating block 16, and the top of the first spring 26 abuts against the bottom of the first annular groove 15.

[0028] A T-shaped block 27 is fixed to the outer wall of the column 2; a T-shaped through groove 28 is provided on the inner wall of the tube 1; the T-shaped block 27 is slidably connected in the T-shaped through groove 28.

[0029] An arc-shaped groove 3 is provided on the outer wall of the fixing block 11; an arc-shaped plate 31 is provided on the arc-shaped groove 3; a sliding block 32 is slidably connected to the outer wall of the arc-shaped plate 31, and a grip groove 33 is provided on the sliding block 32; a thumb plate 34 is fixedly connected to the outer wall of the tube body 1.

[0030] A second groove 35 is provided on the inner wall of the tube body 1; a locking block 36 is slidably connected in the second groove 35; the locking block 36 is fixed to the bottom of the second groove 35 by a spring; a second connecting post 37 is fixed to the side wall of the locking block 36, and the second connecting post 37 extends into the arc groove 3 and is fixed to the side wall of the arc plate 31; a pair of positioning blocks 38 are fixed to the side wall of the column body 2 near the bottom end.

[0031] The top of the side wall of the locking block 36 has a first inclined surface 39.

[0032] The arc-shaped plate 31 has a set of first threaded grooves 4; the sliding block 32 is installed in the first threaded grooves 4 by bolts.

[0033] Working principle: When adsorbing fish eggs in the water, the thumb can be placed in the thumb plate 34, and two or three of the other four fingers can be placed in the grip groove 33 for hand operation. For delicate operation, one hand can be held with the hand open, allowing the locking block 36 to fully enter the second groove 35, while the other hand slowly moves upward by pinching the cover plate 21 to control the rise of the column 2. Then, dead eggs are adsorbed through the suction tube 18. When no delicate operation is required and a rough operation is performed, one hand can be used to perform a cyclical opening and gripping operation with the four fingers. When opening, the column 2... Under the action of the spring, the piston 25 moves upward. When adsorbing dead eggs, liquid is also drawn in. At this time, the spring adsorption will be subject to a certain damping force, which ensures that the overall upward movement distance of the column 2 is limited when the column is opened and gripped. This ensures the upward movement of the piston 25 and completes a single adsorption operation. Because there are multiple sets, multiple adsorptions can be guaranteed. After adsorption, the tube 1 is taken out, and then the four fingers are spread open and the column 2 is pressed down, causing the piston 25 to move down, thereby completing the expulsion of the adsorbed dead eggs. The locking block 36 and positioning block 38 are used to limit the column 2 and complete the fixation operation, making it convenient to carry and use. Because it is an adsorption operation, it can reduce damage to live eggs.

[0034] Meanwhile, the end of the straw 18 is inserted into the outer side of the bottom of the hard tube 17. The straw 18 is an existing technology with a certain degree of deformation at the end, which can wrap around the outer wall of the hard tube 17 without affecting the adsorption of the hard tube 17. In addition, straws 18 of different lengths and tube opening radii can be replaced to make it convenient to be used for different fish egg sizes.

[0035] Finally, the entire device can be disassembled, and the bottom cylinder 14 can be removed from the tube body 1 for cleaning, repair or replacement.
