Mechanical hand-lost joints
The mechanical hand-losing joint is designed to separate the hand-lost hand under the pre-set tension when the tool below is stuck, lift the upper part, and then change the higher strength salvage tool to salvage the lower part. In the case of a stuck, by lifting up, cut the shear pin, to achieve loss. The lifting force can be controlled by adjusting the number of shear pins.

Detailed Description
The mechanical hand-losing joint is designed to separate the hand-lost hand under the pre-set tension when the tool below is stuck, lift the upper part, and then change the higher strength salvage tool to salvage the lower part. In the case of a stuck, by lifting up, cut the shear pin, to achieve loss. The lifting force can be controlled by adjusting the number of shear pins.
The upper and lower joints are cross-recessed to transmit torque.
●Simple structure;
●The shear force can be adjusted in advance
●The position of the hand can be adjusted arbitrarily;
●Built-in 'GS' type salvage neck for easy recycling;
●Reliable sealing performance;
●Able to transmit torque.
