fig. 2 is a schematic view of the structure of the marking plate.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 and 2, the present invention provides an external marking device for anchovy fishes, which comprises a marking plate 100 and a ring clip 200, wherein the marking plate 100 is disposed on the ring clip 200, and is detachably fixed on the branchial cap bone of the anchovy fishes through the ring clip 200.

The tag 100 includes a rectangular plastic sheet 110, and information about anchovy fishes or other information can be written on the side of the plastic sheet 110.

In addition, a two-dimensional code for displaying information on the anchovy or other information is provided on the side of the plastic sheet 110, which facilitates the generation of electronic information.

A circular connecting end 130 is provided at one end of the signboard 100, a connecting hole 131 is provided at the connecting end, and the ring clamp 200 is detachably provided to the signboard 100 through the connecting hole 131.

The circular ring clamp 200 specifically includes a circular ring tube 210 with a hollow interior and a notch, a spring and a lock rod 220 are disposed in the circular ring tube 210, the spring is fixed in the circular ring tube 210, and the lock rod 220 can move in the circular ring tube 210.

Locking lever 220 specifically can be the arc form, its one end and spring coupling, the mouth of pipe of ring pipe 210 one end can be passed to the other end, the mouth of pipe of ring pipe 210 other end is inserted in, when normal, locking lever 220 is all inserted in the mouth of pipe of ring pipe 210 other end, make ring pipe 210 be closed state, only use external force pulling locking lever, make the locking lever overcome the elasticity of spring, thereby make locking lever 220 follow the mouth of pipe of ring pipe 210 other end and shift out, and at this moment ring pipe 210 is in not closed state.

In addition, a sliding groove is formed in the outer surface of the circular tube 210, a control block 211 is arranged on the sliding groove, the control block 211 penetrates through the sliding groove and is fixedly connected with the locking rod 220, and therefore the locking rod can be controlled to move in the circular tube 210 only by controlling the control block 211 to move on the sliding groove, and the use is very convenient.

Therefore, when the signboard 100 is required to be connected with the circular ring clamp 200, the control block 211 is only required to drive the lock rod 220 to move against the elastic force of the spring, so that the lock rod 220 moves out of the pipe orifice at the other end of the circular ring pipe 210, then one end of the circular ring pipe 210 passes through the connecting hole 131 in the plastic sheet 110, and then the lock rod 220 is released, so that the lock rod 220 is inserted into the pipe orifice at the other end of the circular ring pipe 210 again under the elastic force of the spring.

When the marking plate 100 needs to be fixed on the anchovy fish, the control block 211 is only needed to drive the lock rod 220 to move again by overcoming the elastic force of the spring, so that the lock rod 220 is moved out of the pipe orifice at the other end of the circular pipe 210, a gap is reserved between the end part of the lock rod 220 and the pipe orifice at the other end of the circular pipe 210, then the branchial cap bone of the anchovy fish is placed in the gap, then the lock rod 220 is released, and at the moment, the lock rod 220 can prop against the branchial cap bone of the anchovy fish under the elastic force of the spring, so that the anchovy fish is.

In addition, because the locking rod contacts with the branchial cover bone, a rubber sleeve is sleeved at the end part of the locking rod 220, and the diameter of the rubber sleeve is smaller than the diameter of the pipe orifice of the circular tube 210, so that the locking rod can be prevented from crushing the branchial cover bone, the friction force between the locking rod 220 and the branchial cover bone can be increased, and the installation firmness of the circular ring clamp 200 is improved.

Furthermore, since the other end of the circular tube 210 is also in contact with the branchial bone, an annular rubber ring can be disposed at the other end.

The limiting ring 300 is further arranged on the outer surface of the circular tube 210, the limiting ring 300 is used for being matched with the control block 211, when a worker controls the control block 211 to move on the circular tube 210, one hand is needed to hold the circular tube 210, the other hand is needed to control the control block 211 to move, the efficiency is very low, the worker can operate the limiting ring 300 only by one hand through the limiting ring 300, one finger can be used for supporting the limiting ring 300, and then the other finger is used for pushing the control block 211 to move on the circular tube 210, so that the efficiency is improved.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
