The T-type Trailer Release Pin is a quick-release pin with a steel ball locking mechanism. Its core structure includes a T-shaped handle, a pin body, a built-in spring, and a ball assembly. When operating, pressing the handle button can retract the steel ball at the head of the pin body, making it easier to pass through the workpiece hole; after releasing the button, the steel ball pops out to achieve self-locking, ensuring that the pin body cannot be accidentally dislodged. The pin body diameter and clamping length are precisely machined to achieve high repeatability (tolerance can reach ±0.001mm), which is suitable for scenes that require frequent disassembly and assembly and high positioning accuracy.
