Shoe tree anti-unhooking mechanism and shoe tree applying same

Abstract

The utility model discloses a shoe tree anti-unhooking mechanism and a shoe tree using the same. The shoe tree anti-unhooking mechanism comprises a sleeve and a limiting pin arranged in the sleeve in a penetrating mode. Threads are machined on the outer side wall of the sleeve so that the sleeve can be assembled on the top of a shoe tree. The limiting pin comprises a threaded column, a first limiting block fixedly arranged at one end of the threaded column and a second limiting block assembled on the threaded column. The first groove is formed in the top of the shoe tree operating arm and used for being matched with the first limiting block to limit the shoe tree operating arm. The shoe tree disclosed by the utility model is applied to the shoe tree anti-unhooking mechanism. The anti-unhooking mechanism is additionally arranged on the shoe tree, automatic locking or unlocking of the operation arm is achieved through gravity, the unhooking phenomenon generated after locking of the operation arm by a nylon roller fails is effectively avoided, it can be guaranteed that a shoe heel is in a locked state during shoe sole injection molding, shoe delasting is avoided, and the service life of the shoe tree is prolonged. And the quality of finished shoes after injection molding can be ensured.
