III. Structural features
The S-type pulling tool is composed of upper contact, outer cylinder, sleeve, pressing cap, main spring,
secondary spring, spring seat, fishing claw, shear pin, etc.
There are some grooves distributed uniformly on the outer cylinder; the fishing claw is installed on the groove
and shrunk under the function of secondary spring and spring seat; the mandrel is fixed in the outer cylinder
with shear pin; the main spring is installed in the stepped hole on the top of the outer cylinder and pressed
with the pressing cap; the upper connect is connected with the outer cylinder.
While fishing, the outer fishing neck will enter into the outer cylinder to drive the fishing claw to move up,
and then the fishing claw will splay under the function of the slope of outer cylinder and fishing claw; after
continuing to move the outer fishing neck up, the fishing claw will reset under the function of secondary
spring, and then grasp the out fishing neck immediately; at this moment, the upper contact, outer cylinder
and fishing claw connected with the top tool string are bearing the strength of the object to be fished at the
bottom. When the tool moves downward, the outer fishing neck will hold out against the mandrel to cut off
the shear pin; the mandrel will be pulled up under the function of main spring, and the big step of the mandrel
will pull the fishing tool to move up and splay to complete releasing.
