Wherein, on the outer wall of lock core, establish draw-in groove, lock core by draw-in groove in collar is installed in lock body.

Wherein, on the outer wall of stem stem, establish draw-in groove, through collar drive block is installed by draw-in groove on the stem stem.

When unblanking, the key bit of key inserts in the key insertion hole of lock core, key bit pushes back horizontal steel ball hole with steel ball, in lock core, push simultaneously key bit, the briquetting pellet shot from a slingshot that will reset pushes back around the pellet shot from a slingshot hole, fall into the steel ball reseting groove around steel ball, be further rotated key, key drives lock core and realizes release through stem stem interlock drive block.

The utility model adopts horizontal pellet shot from a slingshot and around the locate mode release of reverse while of pellet shot from a slingshot, increases the skilled unlocking difficulty, basic even just can't skilled unlocking, realize real antitheft.
