The principle of release mechanism 5 is as follows:

1. when the electric sliding table 909 moves towards the fry for the first time and pricks the needle into the belly of the fish, the control pull rod 13 also moves towards the clamping device, the pull rod head moves along with the guide groove 12, the pull rod head is blocked by the step surface 1208 of the fourth guide rail groove 1204 during movement and can only slide along the first guide rail groove 1201, and during the complete process of the movement, the control pull rod 13 does not have large horizontal thrust on the whole connecting bottom plate 10, so that the release frame cannot be pushed to leave the fry outlet.

2. After the vaccine injection of the fry is completed, the electric sliding table 909 moves back, at this time, the electric sliding table 909 does not completely return to the initial position, and at this time, the pull rod head of the control pull rod 13 moves along the second guide rail groove 1202 and reaches the connection position of the third guide rail groove 1203 and the second guide rail groove 1202.

3. The electric sliding table 909 moves towards the direction of the fry, but the moving distance is shorter than the first time, the needle of the injector does not contact the fry and does not squeeze the external liquid bag 2, at this time, the pull rod head of the control pull rod 13 enters the third guide rail groove 1203 and finally reaches the end point of the fourth guide rail groove 1204, because the electric sliding table 909 still moves towards the direction of the fry, the pull rod head of the locking pull rod continues to push the releasing connecting plate 11 towards the direction of the fry, and because the releasing connecting plate 11 is connected with the releasing frame, the releasing frame is subjected to horizontal thrust, so that the releasing frame is forced to rotate around the first rotating shaft 15, the releasing frame leaves the fry outlet, and the fry slides out of the releasing mechanism 5 under the action of gravity; subsequently, the electric sliding table 909 moves back, the releasing frame is reset under the action of the torsion spring, and the fry inlet is closed again.

In the above-described release structure, the end of the partition block 1207 near the first arc-shaped rail groove 1206 is preferably a slope 1205, and the slope direction is inclined from the first rail groove 1201 to the second rail groove 1202. Through this setting, make the slip of tie-rod head more smooth. Preferably, of the first rail groove 1201, the second rail groove 1202, the third rail groove 1203 and the fourth rail groove 1204, the third rail groove 1203 has the shortest length, and the third rail groove 1203 plays a transitional role and is arranged to be shorter, so that the structure is more compact, and the stroke required by the electric sliding table 909 is smaller.

Using the apparatus of example 2, the overall injection procedure was as follows:

the first step is as follows: when the fry reaches the position, the fry contacts a touch sensor near the fry outlet, and the touch sensor sends a signal to a device controller;

the second step is that: the device controller controls a motor of the electric sliding table to start, the electric sliding table horizontally moves towards the direction of the fish fries, the needle head penetrates into the belly of the fish surface, and meanwhile, the pull rod head of the control pull rod slides along the first guide rail groove and enters the second guide rail groove;

the third step: after the electric sliding table is in place, the device controller controls the driving motor to be started, so that the injector piston is pushed forwards to inject the vaccine, after the injection is finished, the electric sliding table moves backwards, the needle head leaves the belly of the fry, and the pull rod head of the control pull rod reaches the joint of the second guide rail groove and the third guide rail groove along the second guide rail groove;

the fourth step: the electric sliding rail moves towards the direction of the fish fry for the second time, the stroke is short, the needle head does not contact the fish surface and does not form extrusion force on the external liquid sac, the pull rod head enters the fourth guide rail groove along the third guide rail groove, the pull rod head applies force to the inner wall of the guide groove, the releasing frame rotates anticlockwise, the fish releasing opening is opened, and the fish fry leaves the clamping device by means of gravity;

the fifth step: the electric sliding table slides to the initial position, the control pull rod finally returns to the initial position along the fourth guide rail groove, and the releasing frame returns to the initial position under the driving of the control pull rod and the action of the torsion spring to seal the fry outlet.
