The slip is sleeved on the cone, and the slip is moved up and down along the cone surface of the cone through the compression and expansion of the spring, and the diameter of the slip is changed, thereby changing the fishing range and fishing fish with different inner hole diameter ranges. After the salvage meets obstacles, you can slam the pin downwards, throw off the fish, and raise the salvage spear.

III. Structural features and use:
1. Wireline Releasable Collet Type Bulldog Spear has different sizes and specifications. To catch fish with different inner hole diameters, you only need to replace slips and cones of different specifications. When replacing slips and cones, clamp the self-releasing slip fishing spear upside down on a vise, unscrew the outer cylinder, and then directly remove the slips and cones for replacement. Its structure is simple and easy to use.
2. The method of using Wireline Releasable Collet Type Bulldog Spear. When fishing down the well, the slip moves on the cone surface of the cone to change the diameter of the slip, thereby fishing the fish with different bore diameters.
3. When pulling out, by cutting the shear pin, under the force of the main spring, the outer cylinder drives the slips to move upward, and the fishing spear is raised.
4. Wireline Releasable Collet Type Bulldog Spear needs to reinstall the pin every time the operation is completed. When installing the pin, use the equipped pin installation tool.
IV, matters needing attention:
When replacing the pin, the hexagon socket flat-end set screw must be removed to facilitate the use of the pin assembly tool.
