It has the characteristics of quick disassembly, high strength locking, and repeated high-precision positioning. It is widely used in various industries.

Application scope:

1. Industry / manufacturing industry: textile machinery, tooling, fixture, molding equipment, conveyor belt system, shot blasting processing equipment, all kinds of mold lifting equipment, mining equipment, vehicle tools, scaffolding, trailer frame, folding car, etc.

2. Aerospace / military industry: glider equipment, aircraft engine maintenance equipment, aircraft landing gear equipment, aviation seats, tank doors / hatch covers, field operations, fast bridging, building submarine precision instruments, fast locking, etc.

3. Medical equipment: wheelchair hospital sickbed medical equipment, etc.

4. Entertainment industry: stage sound and lighting suspension system suspended glider (delta wing) climbing equipment fitness equipment hot air balloon racing car (engine cover steering wheel) entertainment vehicles, etc.

5. Ship: sailboat rigging tugboat rudder speedboat cover other marine rigging

Structural features:

1. Press the button on the handle part to retract the steel ball at the head of the pin body and pass the quick drawing pin through the workpiece hole;

2. When the button is released, the steel ball pops up and the quick pull pin cannot be pulled out from the hole;

3. Pin diameter and clamping length are processed with high precision, which are suitable for various high-precision positioning and plugging;

4. Different main materials can be selected according to the use environment and conditions;

5. Various handle types such as L type, T type, B type, R type, C type and Q type can be selected according to different use conditions

Features:

1. T-shaped quick release pin can provide stable and even clamping force, stable and comfortable operation.

2. B-type quick release pin is suitable for occasions with limited operation space around the handle.

3. L-shaped quick release pin is used in the situation that T-shaped handle cannot reach, especially at the right angle.

4. R-type quick release pin is used in a small operating environment around the quick release pin.

5. C type quick release pin, mainly to prevent accidental operation.

6. Q-type quick release pin is a heavy-duty brake pin, which is suitable for occasions with low axial locking requirements and high shear force requirements.
