I. Introduction: (B)
A GS type pulling tool is used to pull inner fishing necks, which can cut off and release an object downward and is usually is used to throw and fishing the lock cylinder, packer, bridge plug and others with inner fishing necks. After connecting the GU joint (upward shear joint), it can be converted to be an upward shear and releasing tool.

Note: More customized parts are available upon request.
III. Structural features: (C)
The GS type pulling tool is mainly composed of fishing neck, shear pin seat, main spring, spring seat, secondary spring, fixed seat of claw, skirt, fishing claw, mandrel, etc..
While the tool is fishing and when the fishing claw just touches the mouth end of the inner fishing neck, it will retreat and fall in the position where the mandrel diameter is a little small and then is taken back; after the fishing claw enters into the inner fishing neck completely, the fishing claw will splay immediately with the thrust of compressed secondary spring.
While throwing it and when the skirt withstands the end face of the inner fishing neck, the tool will move downward can cut off the shear pin because of the relative motion of mandrel and shear pin seat; under the function of main spring and spring seat, the fishing claw and mandrel have relative motion and then the fishing claw withdraws.
The fixed seat of claw can make the fishing claws distributed uniformly and act synchronously.
IV. Method of application:
1. Assemble and disassemble the shear pin:
1.1 Unscrew the shear pin seat and skirt to expose the shear pin hole completely.
1.2 Screw on the tool for installing pins on the top of the fishing neck and screw the handle to align to the shear pin hole.
1.3 Screw up the threads of the shear pin seat and skirt after assembling or disassembling the shear pin.

2. Pulling operation:
2.1 Connect the GS pulling tool with the bottom of the basic tool string.
2.2 Put the tool to be thrown under the GS pulling tool.
2.3 Lower the tool string to the precalculated position and move it downward to cut off the shear pin.
2.4 Pull out the tool string.
3. Fishing operation:
3.1 Connect the GS pulling tool with the bottom of the basic tool string.
3.2 Lower the tool string and confirm whether it reaches the tool to be fished through the weight indicator of the winch on the ground.
3.3 Lift the tool string.
3.4 If the tool string is blocked when it is lifted, it can move down to cut off the shear pin and slip out of the hand.
4. Overground releasing
4.1 Push down the tool to withstand the end of inner fishing neck.

2. Inspect whether the screw joint of GS pulling tool is loose.
V. Disassembly and assembly:
1.1 Remove the shear pin with the tool for installing pins.
1.2 Clamp shear pin seat with a vice.
1.3 Screw off the set screw at the flush end of internal hexagon on the fishing neck with an Allen wrench.
1.4 Lock the opposite side of the mandrel head with a wrench, lock the bottom of the fishing neck with a pipe wrench, and screw off the fishing neck.
1.5 Lock the bottom of pipe wrench and screw off the skirt.
1.6 Pull out the mandrel and take out all parts.
Notes: 1. Don't use the pipe wrench to stick on the fishing diameter of the fishing neck for disassembly to avoid damaging the this face and affecting fishing.
2. Prohibit the use of pipe wrench in the upper thread of the skirt to avoid deformation.
2.1 Clip the fishing claw into the groove of the fixed seat of claw and put it into the skirt.
2.2 Insert the mandrel from the bottom of the skirt.
2.3 Put the secondary spring, spring seat and main spring in the skirt successively.
2.4 Screw on the shear pin seat and reserve a shear pin hole.
2.5 Screw on the fishing neck and install the set screw of the flush end of internal hexagon.
2.6 Install the shear pin with the tool for installing pins.
2.7 Screw up the skirt.
