Metal telescoping structure for changing shoe size and method of use thereof

Abstract

The invention relates to a metal telescopic structure for changing a shoe size and a use method thereof. The structure is characterized in that the structure comprises a fixing plate sheet and a movable plate sheet capable of telescopically positioning, two protruding position limiting sliding plates are arranged at the end, close to the fixing plate sheet, of the movable plate sheet, and elasticstrips and protruding blocks arranged at the ends of the elastic strips are arranged on the sides of the protruding position limiting sliding plates; guiding grooves for the sliding of the protrudingposition limiting sliding plates are arranged in the fixing plate sheet, a plurality of position limiting grooves for limiting positions of the protruding blocks are arranged in the guiding grooves, and pressing strips acting on the elastic strips are arranged on the sides of the fixing plate sheet to drive the elastic strips to retract inward so that the position limiting sliding plates can be free from the position limiting of the position limiting grooves. The metal telescopic structure for changing the shoe size is reasonable in design, convenient in making and low in cost.

Description

Technical field: [0001] The invention relates to a metal telescopic structure for changing the size of shoes and a method of use thereof. Background technique: [0002] With the growth of age, many shoes are too small and can no longer be worn. This problem is accompanied by many teenagers in the growing period, causing great waste; in addition, more and more people now buy shoes through e-commerce, but often buy The size of the returned shoes is not suitable, which has caused the trouble of returning and exchanging goods; in addition, often during travel, due to long journeys, the shoes are too tight, and the feet are covered with bleeding blisters, and there is nothing to do. A convenient and reliable retractable shoe can completely solve these problems. However, the existing stretchable shoes are often complicated in structure and high in cost. Aiming at the existing technology, the present invention proposes a brand-new simple structure, which is mounted on the bottom o...
