Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 5, a crab catching rod device comprises a long rod 1, wherein a mounting slot hole 1a is formed in the long rod 1, the left end of the long rod 1 is slidably provided with a needle head block 2 which can swing up and down, the right end of the needle head block 2 is connected with a string 3, the right end of the thin rope 3 is connected with a thin spring 4 horizontally arranged in the mounting slotted hole 1a, the long rod 1 is hinged with a clamping plate 5 positioned above the needle head block 2, the right side of the clamping plate 5 is provided with a spring 6, one end of the spring is connected with the clamping plate 5, the other end of the spring is connected with the long rod 1, the right end of the splint 5 is abutted with a strip-shaped plate 7 which is hinged in the long rod 1 and is distributed from right to left in an inclined upward manner, the bottom of the strip-shaped plate 7 is connected to the string 3, and the right end of the needle head block 2 is provided with a protruding block 8, the bottom of which abuts against the string 3 and is fixed in the mounting groove hole 1 a.

Through this kind of mode, syringe needle piece 2 is at the in-process that is dragged, pulling string 3 and make strip shaped plate 7 rotate, strip shaped plate 7 breaks away from to close with splint 5, spring 6 releases, do anticlockwise rotation with splint 5 jack-up, thereby make splint 5 tightly press from both sides on syringe needle piece 2, carry out the seizure of crab, through protruding piece 8, make syringe needle piece 2 no matter drag the slip or swing, the homoenergetic pulls string 3 motion, the multiple possibility of seizure has been increased, capture efficiency is greatly improved.

The right side of stock 1 is equipped with bar hole 1b, be connected with the sheet metal 9 that corresponds with bar hole 1b on the string 3. The thin plate 9 is provided with scales 10. In this way, whether the catching is completed or not is judged by observing the change of the scale 10 by the movement of the sheet 9 following the string 3.

Splint 5 includes the arc 51 of upwards arching, straight board 52, the arc 53 of arching downwards and with the contact of BAR 7 that connect gradually from left to right. In this way, the arc-shaped plate 53 arched downwards is beneficial to clamping crabs, and the strip-shaped plate 7 is convenient to be propped against the clamping plate 5 again when the crabs are caught next time.

The left end of the first arc-shaped plate 51 is provided with evenly distributed bulges 51 a. The surface of the crab claw is smooth, and the success rate of catching and clamping is improved by adding the bulge 51 a.

The needle head block 2 comprises a thin needle rod 21 and moving blocks 22 which are connected with the thin needle rod 21 and provided with cylindrical sliding blocks 2a on the front end face and the rear end face. The mounting groove hole 1a is provided with a long chute 11 which is matched with the cylindrical slide block 2a and the right end surface of which is abutted against the cylindrical slide block 2 a. In this way, the sliding and the downhill swinging of the needle block 2 are realized.

The right end of the long rod 1 is connected with a cylindrical handle 12.

The method of use of the present invention is further illustrated below:

when the crab-trapping meat-piece catching device is used, the attracting meat pieces are inserted into the needle head block 2, when the crab-trapping meat pieces are clamped by the crab pincers, the needle head block 2 is driven to pull or swing in the process of touch dragging, the string 3 is pulled, the strip-shaped plate 7 is driven to rotate in the process of pulling the string 3, the strip-shaped plate 7 is separated from the clamping plate 5 to abut against the clamping plate, the clamping plate 5 clamps the needle head block 2 under the action of the spring 6 to tightly clamp the crab pincers of the crab, the crab catching is realized, the change of the scales 10 on the thin plate 9 is observed through the strip-shaped holes 1b, and the catching result is determined to pull the device out of water.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
