[0001] The utility model relates to the technical field of frog catching nets, in particular to a manual frog catching device with convenient replacement of net bags. Background Art

[0002] The benefits and market prospects of artificially breeding frogs are also very impressive. Frog farming is a resource-saving breeding method with a low feed coefficient and efficient resource utilization. For example, the rice frog farming model not only improves economic benefits, but also reduces feed costs through the shading effect. In terms of the market, the consumption of frogs has increased year by year, which has promoted the upgrading and development of the frog industry. In particular, the market demand for species such as bullfrogs is strong, and the prices are relatively high. When frogs mature, they need to be caught, or some frogs need to be caught during their growth process to check their growth. In these cases, frog nets are required for catching. The existing frog nets and the pole body are an integrated structure. When the net bag is damaged, the entire frog net cannot be used, while the pole body used to support the net bag remains intact, which causes waste. To this end, we propose a manual frog catcher that is easy to replace the net bag. Utility Model Content

[0022] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 6 The utility model provides a technical solution: a manual frog catcher with easy replacement of net bags, comprising an annular ring 8 and several net bags 9, each of which is provided with a net bag support ring 6 at the opening, and the net bag support ring 6 is used to support the opening of the net bag 9. The net bag support ring 6 in this application is a rope or a metal wire, and the net bag support ring 6 is a closed annular structure.

[0024] The bottom of the annular ring 8 is provided with a plurality of supports 7 arranged at intervals, such as Figure 1 and Figure 4 As shown, the supports 7 are specifically arranged in a ring shape, and the outer diameter of the space enclosed by the supports 7 matches the size of the net bag support ring 6, that is, the gap between the two is matched, so that when the net bag support ring 6 is put on the outside of the space enclosed by the supports 7, the gap between the net bag support ring 6 and the supports 7 will not be too large.

[0025] like Figure 4 As shown, a reinforcement portion 5 is provided on the side of the annular ring 8, which is specifically a triangular seat body, and a draw hook 10 is provided below the reinforcement portion 5, as shown in FIG. Figure 5 As shown, the hook 10 is hooked on the net bag support ring 6, and the hook 10 is installed on the screw adjustment mechanism, which is used to drive the hook 10 to move in the radial direction of the annular ring 8. Figure 4 As shown, the screw adjustment mechanism specifically includes a mounting seat 12 mounted on the bottom of the reinforcement portion 5, and the mounting seat 12 is internally threadedly connected to an adjustment screw 13 radially arranged with the annular ring 8;

[0026] The retractor 10 is L-shaped and rotatably mounted on the end of the adjusting screw 13. Specifically, one end of the retractor 10 is connected to the side of a connecting seat 15. The connecting seat 15 is annular. One end of the adjusting screw 13 is movably placed in the connecting seat 15. A stopper 14 is provided at the end of the adjusting screw 13 to prevent the connecting seat 15 from falling off, so that the connecting seat 15 can rotate freely around the end of the adjusting screw 13 without falling off.

[0027] The end of the adjusting screw 13 away from the hook 10 is provided with a screw head 16. When in use, the adjusting screw 13 is rotated by screwing the screw head 16 with a tool such as a wrench or a vise. Figure 5 As shown, the adjusting screw 13 drives the hook 10 to pull the net bag support ring 6 in a direction away from the center of the annular ring 8, so that the net bag support ring 6 can be tightly tightened on the support 7. It should be noted that the net bag support ring 6 is not elastic and has to be strong enough.

[0028] Furthermore, two blocks 11 are provided at one end of the bottom of the reinforcement part 5 near the annular ring 8. The two blocks 11 are symmetrically distributed on both sides of the adjusting screw 13. When the hook 10 pulls the net bag support ring 6, the net bag support ring 6 contacts the blocks 11, which actually makes the blocks 11 and each support 7 in the same annular ring. In this way, the blocks 11 can play a supporting role when the net bag support ring 6 is stretched and deformed, so that the shape of the net bag support ring 6 remains unchanged.

[0029] In the above process, driven by the screw adjustment mechanism, the hook 10 pulls the net bag support ring 6 to tighten on each support 7, and the side of the support 7 away from the center of the annular ring 8 is provided with a groove for accommodating the net bag support ring 6, and a groove for accommodating the net bag support ring 6 is also provided on the surface of the block seat 11. The net bag support ring 6 is placed in the groove, so that the net bag support ring 6 can be placed in the groove when it is pulled, which makes the net bag support ring 6 more stable and will not fall off from the support 7.

[0030] Further, such as Figure 1 and Figure 2 As shown, one end of the reinforcement part 5 is connected to the telescopic rod, which facilitates the operator to adjust the extension length of the net bag, thereby increasing the capture range of the net bag. The telescopic rod includes an adjustment rod 4, one end of which is connected to the end of the reinforcement part 5, and the other end of which is movably placed in the support tube 1. A positioning device is provided at the end of the support tube 1 to adjust the adjustment rod 4 to a preset length. Figure 3As shown, the positioning device includes an annular seat 2 arranged at the end of the support tube 1, and an annular groove is provided on the surface of the annular seat 2, and a plurality of openings 17 are provided on the annular seat 2 and radially arranged therewith. A quick-release pipe clamp 3 is provided in the annular groove. When the quick-release pipe clamp 3 is tightened, the quick-release pipe clamp 3 drives each opening to contract, so that the annular seat 2 is tightly tightened on the adjusting rod 4, so that the adjusting rod 4 and the support tube 1 are fixed. When the quick-release pipe clamp 3 is opened, the length between the adjusting rod 4 and the support tube 1 can be adjusted at will.

[0031] In summary, the net bag 9 for catching frogs is easy to assemble and disassemble. That is, when assembling the net bag 9, it is only necessary to put the net bag support ring 6 on the support 7, then hook the net bag support ring 6 with the retractor 10, and then pull the net bag support ring 6 by adjusting the adjusting screw 13, so that the net bag support ring 6 is pulled and contracted by the retractor 10, so that the net bag support ring 6 is fixed under the annular ring 8; conversely, by loosening the adjusting screw 13, the retractor 10 is separated from the net bag support ring 6, and the net bag 9 can be removed, and the damaged net bag 9 can be replaced;

[0032] Moreover, the gap between the net bag support ring 6 and the annular ring 8 is small, and the gap between the two will not leak frogs. The annular ring 8 is a hollow tube with a relatively thick diameter, which can effectively support the net bag, making the net bag have a large load capacity. Since the net bag is at the bottom of the annular ring 8, when holding the telescopic rod to catch frogs, the annular ring 8 is in contact with the ground, and the edge of the net bag will not collide with the ground, thereby avoiding damage to the edge of the net bag.

[0033] Based on the above embodiment, further optimization can be performed by providing nuts on the adjusting screws on both sides of the mounting seat 12. When the adjusting screws are in place, they can be fixed by the nuts to prevent the adjusting screws from loosening during use.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
