Abstract

This invention relates to the field of bullfrog slaughtering technology, specifically to a frog-pressing device and a frog-killing device using the frog-pressing device. The device includes a support part and a pressing part. The support part acts on the external abdomen of the bullfrog, while the pressing part acts on the internal abdomen. The support part and the pressing part cooperate to clamp the bullfrog's abdomen. The clamping force of the support part and the pressing part is adjustable. During the process of tearing the frog skin, the force exerted by the pressing part on the bullfrog's abdomen is greater than the force exerted by the support part. The pressing part and the support part cooperate to clamp the bullfrog's abdomen, controlling the clamping force to prevent the bullfrog's abdomen from being clamped too tightly. After the frog skin and frog meat separate from the abdomen, the clamping force is increased to stably clamp the bullfrog's abdominal flesh. Then, the moving speed of the skinning mechanism is increased to achieve skin-meat separation. Regardless of individual differences among bullfrogs, the bullfrog can be stably clamped, achieving skin-meat separation and improving the flexibility of bullfrog skin-meat separation.

Description

Technical Field

[0001] This invention relates to the field of bullfrog slaughtering technology, specifically to a frog-pressing device and a frog-killing device using the frog-pressing device. Background Technology

[0002] To obtain bullfrog skin, bullfrogs usually need to be slaughtered. Traditional slaughtering methods are mostly done manually. Manual work has a high repetition rate, and operators are prone to fatigue during long slaughtering processes, which reduces the efficiency of slaughtering bullfrogs and is not conducive to slaughtering bullfrogs. In order to improve the efficiency of slaughtering bullfrogs, mechanical equipment is usually needed.

[0003] In response to this situation, there is currently an automatic bullfrog slaughtering and processing equipment on the market, such as the Chinese patent with application number CN202111480762.2. This automatic bullfrog slaughtering and processing equipment includes a skin-meat separation device, which includes a left gripper, a right gripper, and a gripper drive mechanism. The left gripper and the right gripper are arranged opposite to each other. The gripper drive mechanism is installed on the gripper seat and drives the left gripper and the right gripper to move relative to each other to form a clamping action to clamp the bullfrog skin. Then, the skinning motor drives the gripper holding the bullfrog skin to move, pulling the bullfrog skin away from the bullfrog meat, thus realizing the operation of separating the skin and meat.

[0004] However, while this skin-meat separation device can separate bullfrog skin from bullfrog meat, the inventors discovered shortcomings in its practical use, specifically:

[0005] During the process of separating the skin and flesh of bullfrogs, it is usually necessary to fix the bullfrog in place.

[0006] When a bullfrog is clamped and fixed from its body, the clamping parts hold the bullfrog skin and the bullfrog flesh under the skin. During the process of pulling the bullfrog skin away from the bullfrog flesh, the skin in the clamped part will not be pulled off, resulting in some skin remaining on the bullfrog flesh, which is not conducive to the separation of the bullfrog skin and flesh.

[0007] When supporting and securing a bullfrog from its body, the process typically involves first cutting open the abdomen to remove the internal organs. Then, the support component is inserted through the opening and placed inside the bullfrog. The component is then unfolded to secure the bullfrog from within. Finally, the skin is pulled away from the flesh to separate it from the meat. The force applied by the skin-tearing component to the skin needs adjustment. If the force is too great, the bullfrog flesh may detach from the support component at the opening, causing the flesh and skin to move together and preventing separation. If the force is too small… This can lead to the bullfrog skin taking a long time to tear off the bullfrog meat, or even failing to tear off at all, resulting in the skin and meat remaining inseparable. Therefore, different batches of bullfrogs, with variations in individual size, require different application forces to achieve proper skin-to-meat separation. In particular, if bullfrogs with significant individual differences are mixed in within the same batch, the application force set for that batch may be too strong or too weak during the skin-to-meat separation process, hindering the separation.

[0008] Therefore, based on the above shortcomings, there is an urgent need to design a frog-pressing device for slaughtering bullfrogs and a frog-killing device using the frog-pressing device, so as to fix the bullfrog meat during the process of separating the bullfrog skin and meat, and improve the flexibility of separating the bullfrog skin and meat. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of current methods for properly securing the bullfrog's body during the skin-meat separation process, by providing a frog-pressing device and a frog-killing device using the frog-pressing device, which is used to secure the bullfrog's body during the skin-meat separation process, thereby improving the flexibility of the skin-meat separation process.

[0010] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0011] A frog-pressing device includes a support part and a pressing part. The support part acts on the abdomen outside the bullfrog's body, and the pressing part acts on the abdomen inside the bullfrog's body. The support part and the pressing part cooperate to clamp the bullfrog's abdomen. The clamping force of the support part and the pressing part is adjustable. During the process of tearing the bullfrog's skin, the force exerted by the pressing part on the bullfrog's abdomen is greater than the force exerted by the support part on the bullfrog's abdomen.

[0012] As the preferred technical solution of this application, the pressing part includes a first pressure main arm and a second pressure main arm, which are rotatably connected. The first pressure main arm and the second pressure main arm rotate and cooperate to realize the opening or closing operation, and when closed, it is in a straight line shape, and when open, it is in a V shape.

[0013] As the preferred technical solution of this application, the first pressure main arm and the second pressure main arm are conical, and during the process of the first pressure main arm and the second pressure main arm entering the bullfrog's body, the small end of the cone enters the bullfrog's body first.

[0014] As the preferred technical solution of this application, the side of the first pressure main arm and the second pressure main arm that contacts the bullfrog's abdomen is provided with serrations.

[0015] As the preferred technical solution of this application, the support part includes a support platform, and the support platform is provided with a boss. When the support platform contacts the bullfrog's abdomen, the boss extends into the bullfrog's body through the slit in the bullfrog's abdomen.

[0016] As the preferred technical solution of this application, a first pressure auxiliary arm is provided on the first pressure main arm, and a second pressure auxiliary arm is provided on the second pressure main arm. By acting on the first pressure auxiliary arm and the second pressure auxiliary arm, the first pressure main arm and the second pressure main arm are rotated to realize the opening or closing action. A base is provided on the first pressure auxiliary arm and the second pressure auxiliary arm. When the base moves, the first pressure auxiliary arm and the second pressure auxiliary arm move with the base.

[0017] As the preferred technical solution of this application, a spring is connected between the first pressure auxiliary arm and the second pressure auxiliary arm. The spring keeps the first pressure auxiliary arm and the second pressure auxiliary arm in a natural state. In the natural state, the first pressure main arm and the second pressure main arm are closed in a straight line. The first pressure auxiliary arm and the second pressure auxiliary arm are movably connected to a first driving device. The first driving device is used to rotate the first pressure auxiliary arm and the second pressure auxiliary arm, and synchronously drive the first pressure main arm and the second pressure main arm to rotate, so that the first pressure main arm and the second pressure main arm open in a V-shape.

[0018] As the preferred technical solution of this application, the first driving device is a push block, which acts on the first pressure arm and the second pressure arm to rotate the first pressure arm and the second pressure arm. The push block is connected to a cylinder, which provides power for the movement of the push block. The cylinder is fixed on the base.

[0019] As the preferred technical solution of this application, a limiting block is provided on the base, the limiting block is used to limit the movement stroke of the push block, the limiting block is movably connected to the base, and a fastening knob is provided on the base, the fastening knob is used to fix the position of the limiting block relative to the base.

[0020] As the preferred technical solution of this application, the base is provided with a first moving device, which is used to drive the pressing part to move laterally, so as to realize the action of the pressing part entering the bullfrog's body from the outside of the bullfrog's body. The base is provided with a second moving device, which is used to drive the pressing part to move vertically, so as to realize the pressing part pressing down on the bullfrog's abdomen.

[0021] To achieve the above-mentioned objectives, the present invention also provides the following technical solutions:

[0022] A frog-killing device, wherein the frog-killing device employs the frog-pressing device.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. In the scheme of this application, after the preceding steps of removing the head, eviscerating, and gutting the bullfrog, the support part is moved to the lower part of the bullfrog's abdomen. Simultaneously, the clamping part is inserted into the bullfrog's body through the opening from which the head was removed. At the same time, the skinning mechanism is controlled to clamp the bullfrog skin. Then, the clamping part is moved downwards, bringing it closer to the support part. The clamping part and the support part work together to clamp the bullfrog's abdomen. At this point, the bullfrog's skin and meat are clamped together. The clamping force is controlled to prevent the bullfrog's abdomen from being clamped too tightly. Finally, the skinning mechanism is controlled to move slowly. Because the force exerted by the pressing part on the bullfrog's abdomen is greater than that exerted by the supporting part on the bullfrog's abdomen, the bullfrog's abdominal flesh remains relatively stationary under the action of the pressing part. The bullfrog's abdominal skin moves with the peeling mechanism. After the bullfrog's abdominal skin separates from the frog meat, the clamping force is increased to stably clamp the bullfrog's abdominal flesh. Then, the moving speed of the peeling mechanism is increased to achieve a rapid separation of skin and flesh. In this way, regardless of individual differences among bullfrogs, they can be stably clamped to achieve the separation of skin and flesh, thus improving the flexibility of bullfrog skin and flesh separation.

[0025] 2. The notch after removing the head of the bullfrog is usually small. When the first and second pressure arms are closed, they form a straight line, which reduces the cross-sectional area of ​​the clamping part. This makes it easier to insert the clamping part into the bullfrog's body. Once inserted into the bullfrog's body, the first and second pressure arms are opened to form a V-shape, which increases the distance between the first and second pressure arms and the cut in the bullfrog's abdomen, thus facilitating the clamping of the bullfrog's abdomen.

[0026] 3. The side of the boss forms an angle with the support platform. The first and second pressure arms open and work with the support to clamp the bullfrog's abdomen. Under the combined action of the first or second pressure arms, the side of the boss, and the support platform, the clamped part of the bullfrog bends. The first or second pressure arms and the side of the boss clamp the bullfrog. At the same time, the first or second pressure arms and the support platform clamp the bullfrog, increasing the force on the bullfrog's body from different directions, improving the stability of the bullfrog's body when it is clamped, and facilitating the separation of the bullfrog's skin and flesh.

[0027] 4. The spring design ensures that the first and second main pressure arms are closed in a straight line when in a self-heating state. During the movement of the clamping part, the first and second main pressure arms will not open, which facilitates the insertion or withdrawal of the first and second main pressure arms into or from the bullfrog's body through the notch after the bullfrog's head is removed. Under the action of the first driving device, the first and second auxiliary pressure arms rotate, causing the first and second main pressure arms to rotate and open into a V-shape. After opening, the first and second main pressure arms, together with the support part, clamp the bullfrog's abdomen.

[0028] 5. The setting of the limiting block restricts the movement stroke of the push block, which in turn limits the opening angle of the first and second pressure arms. If the opening angle is too small, the first and second pressure arms may be unstable when they work with the support to clamp the bullfrog's abdomen. If the opening angle is too large, the first and second pressure arms may damage the inner wall of the bullfrog's flesh, both of which are detrimental to the separation of the bullfrog's skin and flesh. By setting the limiting block to the base in a movable connection and fixing the position of the limiting block relative to the base with a fastening knob, the opening angle of the first and second pressure arms can be adjusted. This achieves stable clamping of the bullfrog without damaging the inner wall of the bullfrog's flesh, improving the flexibility of bullfrog fixation and facilitating the separation of the bullfrog's skin and flesh.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Example 1: See Figure 1-6 As shown,

[0042] This embodiment provides a frog-pressing device, including a support part 1 and a pressing part 2. The support part 1 acts on the abdomen outside the bullfrog, and the pressing part 2 acts on the abdomen inside the bullfrog. The support part 1 and the pressing part 2 cooperate to clamp and fix the abdomen of the bullfrog.

[0043] After the preceding processes of removing the head, eviscerating, and gutting the bullfrog, the support part 1 is moved to the lower part of the bullfrog's abdomen. Simultaneously, the clamping part 2 is inserted into the bullfrog's body through the opening from which the head was removed. At the same time, the skinning mechanism 30 is controlled to clamp the bullfrog skin. The clamping part 2 is then moved downwards, bringing it closer to the support part 1. The clamping part 2 and the support part 1 work together to clamp the bullfrog's abdomen. At this point, the bullfrog's skin and meat are clamped together. The clamping force is controlled to prevent the bullfrog's abdomen from being clamped too tightly. Then, the skinning mechanism 30 is slowly moved. The force exerted by the pressing part 2 on the bullfrog's abdomen is greater than that exerted by the supporting part 1. Under the action of the pressing part 2, the bullfrog's abdominal flesh remains relatively stationary, while the frog skin moves with the peeling mechanism 30. After the frog skin separates from the frog meat, the clamping force is increased to stably hold the bullfrog's abdominal flesh. Then, the moving speed of the peeling mechanism 30 is increased to achieve rapid skin-meat separation. In this way, regardless of individual differences among bullfrogs, they can be stably clamped to achieve skin-meat separation, thus improving the flexibility of bullfrog skin-meat separation.

[0044] In a preferred embodiment, based on the above method, the pressing part 2 further includes a first pressure main arm 211 and a second pressure main arm 212, the first pressure main arm 211 and the second pressure main arm 212 are rotatably connected, and the first pressure main arm 211 and the second pressure main arm 212 rotate to achieve the opening or closing operation, and when closed, it is in a straight line shape, and when open, it is in a V shape.

[0045] The notch after removing the head from a bullfrog is usually small. When the first pressure arm 211 and the second pressure arm 212 are closed, they form a straight line, which reduces the cross-sectional area of ​​the clamping part 2. This makes it easier to insert the clamping part 2 into the bullfrog's body. The first pressure arm 211 and the second pressure arm 212 inserted into the bullfrog's body are then opened to form a V-shape, which increases the distance between the first pressure arm 211 and the second pressure arm 212 and the cut-open part of the bullfrog's abdomen, thus facilitating the clamping of the bullfrog's abdomen.

[0046] As a preferred embodiment, based on the above method, the first pressure main arm 211 and the second pressure main arm 212 are tapered, and during the process of the first pressure main arm 211 and the second pressure main arm 212 entering the bullfrog's body, the smaller end of the tapered shape enters the bullfrog's body first.

[0047] The opening after the bullfrog's head is removed is usually small. The first pressure main arm 211 and the second pressure main arm 212 are set into a cone shape. During the process of the first pressure main arm 211 and the second pressure main arm 212 entering the bullfrog's body, the small end of the cone enters the bullfrog's body first. The small end of the cone further reduces the cross-sectional area of ​​the pressing part 2, which is more conducive to sending the pressing part 2 into the bullfrog's body.

[0048] As a preferred embodiment, based on the above method, the side of the first pressure arm 211 and the second pressure arm 212 that contacts the bullfrog's abdomen is provided with serrations.

[0049] The serrated design increases the friction between the first pressure arm 211 and the second pressure arm 212 and the bullfrog's abdominal flesh. During the process of separating the skin and flesh of the bullfrog's abdomen, it reduces the tendency of the bullfrog's abdominal flesh to move as the frog skin is removed, which is beneficial to the separation of the skin and flesh of the bullfrog's abdomen.

[0050] As a preferred embodiment, based on the above method, the support part 1 further includes a support platform 11, on which a boss 12 is provided. When the support platform 11 contacts the bullfrog's abdomen, the boss 12 extends into the bullfrog's body through the cut in the bullfrog's abdomen.

[0051] The side of the boss 12 forms an angle with the support platform 11. The first pressure arm 211 and the second pressure arm 212 open up and work with the support part 1 to clamp the bullfrog's abdomen. Under the combined action of the first pressure arm 211 or the second pressure arm 212, the side of the boss 12, and the support platform 11, the clamped part of the bullfrog bends. The first pressure arm 211 or the second pressure arm 212 and the side of the boss 12 form a clamp on the bullfrog. At the same time, the first pressure arm 211 or the second pressure arm 212 and the support platform 11 form a clamp on the bullfrog, which increases the force on the bullfrog's body from different directions, improves the stability of the bullfrog's body when it is clamped, and is conducive to the separation of the bullfrog's skin and flesh.

[0052] Example 2: See Figure 4-6 As shown,

[0053] Based on the technical solution of Embodiment 1, the first pressure main arm 211 is further provided with a first pressure auxiliary arm 221, and the second pressure main arm 212 is provided with a second pressure auxiliary arm 222. By acting on the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, the first pressure main arm 211 and the second pressure main arm 212 are rotated to realize the opening or closing action. The first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 are provided with a base 23. When the base 23 moves, the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 move with the base 23.

[0054] The arrangement of the first pressure arm 221 and the second pressure arm 222 divides the clamping part 2 into two parts. The front part includes only the first pressure arm 211 and the second pressure arm 212, while the rear part includes the first pressure arm 221, the second pressure arm 222, and the mechanical structure required to rotate or move the first pressure arm 221 and the second pressure arm 222. This arrangement makes the front part smaller in size, which is conducive to inserting the front part into the bullfrog's body. Then, by rotating or moving the rear part, the bullfrog can be clamped, which is conducive to separating the bullfrog's skin and flesh.

[0055] In a preferred embodiment, based on the above method, a spring 24 is further connected between the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222. The spring 24 keeps the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 in a natural state. In the natural state, the first pressure main arm 211 and the second pressure main arm 212 are closed in a straight line. The first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 are movably connected to a first driving device 25. The first driving device 25 is used to rotate the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, and synchronously drive the first pressure main arm 211 and the second pressure main arm 212 to rotate, so that the first pressure main arm 211 and the second pressure main arm 212 open in a V-shape.

[0056] The spring 24 ensures that the first pressure main arm 211 and the second pressure main arm 212 are closed in a straight line when in a self-heating state. During the movement of the clamping part 2, the first pressure main arm 211 and the second pressure main arm 212 will not open, which is beneficial for inserting the first pressure main arm 211 and the second pressure main arm 212 into the bullfrog's body through the notch after the bullfrog's head is removed, or for withdrawing them from the bullfrog's body. Under the action of the first driving device 25, the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 rotate, causing the first pressure main arm 211 and the second pressure main arm 212 to rotate and open into a V-shape. After opening, the first pressure main arm 211 and the second pressure main arm 212 work together with the support part 1 to clamp the bullfrog's abdomen.

[0057] In a preferred embodiment, based on the above method, the first driving device 25 is a push block 251, which acts on the first pressure arm 221 and the second pressure arm 222 to rotate the first pressure arm 221 and the second pressure arm 222. The push block 251 is connected to a cylinder 252, which provides power for the movement of the push block 251. The cylinder 252 is fixed on the base 23.

[0058] Under the action of cylinder 252, push block 251 moves forward, and push block 251 acts on the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222. The first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 rotate, and the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 drive the first pressure main arm 211 and the second pressure main arm 212 to rotate and open. Under the action of cylinder 252, push block 251 retracts backward, and push block 251 disengages from the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222. Under the action of spring 24, the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 rotate, and the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222 drive the first pressure main arm 211 and the second pressure main arm 212 to rotate and close.

[0059] As a preferred embodiment, based on the above method, a limiting block 26 is further provided on the base 23. The limiting block 26 is used to limit the movement stroke of the push block 251. The limiting block 26 is movably connected to the base 23. A fastening knob 27 is provided on the base 23. The fastening knob 27 is used to fix the position of the limiting block 26 relative to the base 23.

[0060] The setting of the limiting block 26 restricts the movement stroke of the push block 251. The movement stroke of the push block 251 restricts the opening angle of the first pressure main arm 211 and the second pressure main arm 212. If the opening angle is too small, the first pressure main arm 211 and the second pressure main arm 212 may cause instability when they work with the support part 1 to clamp the bullfrog's abdomen. If the opening angle is too large, the first pressure main arm 211 and the second pressure main arm 212 may damage the flesh of the bullfrog's inner sidewall. Neither of these is conducive to the separation of the bullfrog's skin and flesh. By setting the limiting block 26 and the base 23 to be movably connected, and fixing the position of the limiting block 26 relative to the base 23 by the fastening knob 27, the opening angle of the first pressure main arm 211 and the second pressure main arm 212 can be adjusted. This can achieve stable clamping of the bullfrog without damaging the flesh of the bullfrog's inner sidewall, improve the flexibility of bullfrog fixation, and facilitate the separation of the bullfrog's skin and flesh.

[0061] Example 3: See Figure 2-5 As shown,

[0062] Based on the technical solution of Embodiment 1, the base 23 is further provided with a first moving device 28, which is used to drive the pressing part 2 to move laterally, so as to realize the action of the pressing part 2 entering the bullfrog body from the outside of the bullfrog body. The base 23 is provided with a second moving device 29, which is used to drive the pressing part 2 to move vertically, so as to realize the pressing part 2 pressing down on the bullfrog abdomen.

[0063] Under the action of the first moving device 28, the base 23 moves closer to the notch after the bullfrog's head is removed. The base 23, along with the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, moves closer to the notch after the bullfrog's head is removed. The first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, along with the first pressure main arm 211 and the second pressure main arm 212, enter the bullfrog's body through the notch after the bullfrog's head is removed. Under the action of the second moving device 29, the base 23 moves downward. The base 23, along with the first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, moves downward. The first pressure auxiliary arm 221 and the second pressure auxiliary arm 222, along with the first pressure main arm 211 and the second pressure main arm 212, move downward. The first pressure main arm 211 and the second pressure main arm 212 move closer to the bullfrog's abdomen from inside the bullfrog's body. With the cooperation of the support part 1, the abdominal flesh of the bullfrog is clamped.

[0064] Example 4: See Figure 1-6 As shown,

[0065] This embodiment also provides a frog-killing device, which adopts the frog-pressing device described in the previous embodiment.

The first or second pressure arms and the side of the boss form a clamp on the bullfrog, and at the same time, the first or second pressure arms and the support platform form a clamp on the bullfrog.

2. The frog-pressing device as described in claim 1, characterized in that: The first pressure arm and the second pressure arm are conical, and during the process of the first pressure arm and the second pressure arm entering the bullfrog's body, the smaller end of the cone enters the bullfrog's body first.

3. The frog-pressing device as described in claim 1, characterized in that: The sides of the first and second pressure arms that contact the bullfrog's abdomen are provided with serrations.

4. The frog-pressing device as described in claim 1, characterized in that: The first pressure main arm is provided with a first pressure auxiliary arm, and the second pressure main arm is provided with a second pressure auxiliary arm. By acting on the first pressure auxiliary arm and the second pressure auxiliary arm, the first pressure main arm and the second pressure main arm are rotated to achieve the action of opening or closing. The first pressure auxiliary arm and the second pressure auxiliary arm are provided with a base. When the base moves, the first pressure auxiliary arm and the second pressure auxiliary arm move with the base.

5. The frog-pressing device as described in claim 4, characterized in that: A spring connects the first pressure arm and the second pressure arm, which keeps the first pressure arm and the second pressure arm in a natural state. In the natural state, the first pressure arm and the second pressure arm are closed in a straight line. The first pressure arm and the second pressure arm are movably connected to a first driving device, which is used to rotate the first pressure arm and the second pressure arm, and synchronously drive the first pressure arm and the second pressure arm to rotate, so that the first pressure arm and the second pressure arm open in a V-shape.

6. The frog-pressing device as described in claim 5, characterized in that: The first driving device is a push block, which acts on the first pressure arm and the second pressure arm to rotate. The push block is connected to a cylinder, which provides power for the movement of the push block. The cylinder is fixed on the base.

7. The frog-pressing device as described in claim 6, characterized in that: The base is provided with a limiting block, which is used to limit the movement stroke of the push block. The limiting block is movably connected to the base. The base is provided with a fastening knob, which is used to fix the position of the limiting block relative to the base. The base is provided with a first moving device, which is used to drive the pressing part to move laterally, so as to realize the action of the pressing part entering the bullfrog's body from the outside of the bullfrog's body. The base is provided with a second moving device, which is used to drive the pressing part to move vertically, so as to realize the pressing part pressing down on the bullfrog's abdomen.
