Key-locked insert is a new-style fastener for screw threads

which has many advantages such as convenient installation

reliably connection

easy disassembly

can solve some problems in use of wire thread insert. Combining with the working experience

the structural characteristic of the key-locked insert and its installing principle are introduced. The method of installation

technological parameter and application effect on the resin matrix composites are also discussed. The results of application indicated that to use technology of pneumatic punching press can safety assembly

high installation efficiency and easy disassembly in the resin metrix composites.
