This invention discloses a fish-engaging hooker, comprising a first slide rail and a hooking assembly. A sliding seat is provided on the first slide rail, and the hooking assembly is mounted on the sliding seat and can slide along the first slide rail with the sliding seat. An anti-slip structure is provided between the sliding seat and the first slide rail to fix the sliding seat on the first slide rail. By setting up a first slide rail, mounting a sliding seat on the first slide rail, and mounting the hooking assembly on the sliding seat, this invention allows control of the sliding seat and the entire hooking assembly to slide along the first slide rail when fish enticing is needed. This keeps the relative position of the fishing rod and the hooker unchanged during the enticing process, enabling rapid activation of the hooker when a fish bites and drags the fishing rod, thus improving the practicality of the hooker and increasing the efficiency of catching fish.

Elongate capsules for housing waste are configured for disposal (placement) into wellbore(s) that are located in particular deep underground geologic formation(s). These capsules have opposing structures for physically linking multiple capsules together in an end-to-end fashion. These opposing end structures may include a stinger with pins at a top end of the capsule; and a J-slots structure at the bottom end of the capsule. The stinger with pins of a first capsule may be (removably) attached to the J-slots of a second capsule. Further, a retrieval-tool also has the J-slots structure at one end. The J-slots structure of the retrieval-tool may be configured to (removably) attach to a stinger with pins of a given capsule (which may be linked to other capsule(s)); and then the retrieval-tool may be used to retrieve the given capsule(s) from a given wellbore. Capsule retrieval systems and / or method may utilize such capsule(s) and the retrieval-tool.

The utility model discloses a wasp venom taking device, including box, the box open plane is set with multiple electrode stick in the gap evenly, multiple electrode stick longitudinal or transverse arrangement, at its both ends interval through the connector and be communicated to the power supply, the box is laid down one layer of nylon net under the electrode stick, and the lower surface of nylon net and electrode stick is attached or gap setting, the box is still equipped with glass plate under nylon net, wherein glass plate and box form the pull -out type structure. Multiple electrode stick can provide a gap for the job bee and climb, because the job bee's climb is impossible all one direction, so the interval of both ends electrification will make the wasp can be on the basis of irregular, all can realize electric shock and make it detoxification; The lower surface of nylon net and electrode stick is attached or gap setting; It is convenient for the job bee and detoxifies, and the problem that the individual difference can exist also all detoxifies; Glass plate and box form the pull -out type structure, when the bee venom gathers to certain quantity, can replace collection.
