[0028] Refer to Figure 3 and Figure 4, the vibration mechanism 9 includes an outer frame 91. On one side of the inner wall of the outer frame 91, a driving motor 92 is fixedly connected. On the output shaft of the driving motor 92, a cam 93 is fixedly connected. Between the two sides of the inner wall of the outer frame 91, a concave plate 94 is slidably connected. On the top of the concave plate 94, a vibrating rod 95 is fixedly connected. The top end of the vibrating rod 95 penetrates through the support plate 7 and is fixedly connected to the bottom of the lowermost positioning plug 4. Between the two sides of the inner wall of the outer frame 91, a cross plate 96 is also fixedly connected. On both sides of the top of the cross plate 96, a reset spring 97 is fixedly connected. The top ends of the two groups of reset springs 97 are fixedly connected to the bottom of the concave plate 94. The driving motor 92 can control the rotation of the cam 93, and then through the reset spring 97, the concave plate 94 can be reset, so as to realize the up and down movement of the concave plate 94.

[0029] Referring to Figure 3 , the top of the cam 93 always abuts against the bottom of the concave plate 94, and the concave part of the concave plate 94 is located below, which improves the control effect of the vibration mechanism 9.

Then the box door 2 is closed, and the freezing mechanism 10 is started. It generates cold air with a relatively low temperature, which is transmitted to various parts inside the outer box 1 through the U-shaped cooling pipe 11, and then the shrimps on the quick-freezing grid 8 are frozen. During the freezing process, the driving motor 92 is started. The output shaft of the driving motor 92 drives the cam 93 to rotate. Then through the provided reset spring 97, when the cam 93 continuously rotates, the concave plate 94 can move up and down, so that the vibrating rod 95 moves up and down, and further drives the multiple groups of positioning plugs 4 to move up and down, making the quick-freezing grid 8 vibrate, so that the shrimps are quickly frozen during the vibration process, reducing the adhesion between the shrimps and at the same time reducing the adhesion of the shrimps to the quick-freezing grid 8, improving the use effect of the quick-freezing of the shrimps.
