Shoe stretcher

Abstract

The invention discloses a shoe stretcher, which comprises a sole widening assembly and a heel extension assembly; the sole widening assembly comprises two shells, a first bearing, a first gear, a main transmission rod, a second gear, a threaded rod, a T-shaped block, a supporting column, a second bearing, a positioning ring, a third bearing, a sole shoe tree shell, a heel shoe tree shell and a limiting ring. The inner side walls of the two shells are in threaded connection through nuts, a first bearing is clamped to the bottoms of the adjacent sides of the two shells, a first gear is clamped to the inner ring of the first bearing, a main transmission rod is clamped to the positions, located on the inner side walls of the first gear, of the adjacent sides of the two shells; and through meshing connection between the gears, a user can operate the shoe stretcher more smoothly; and the connecting angle between the main transmission rod and the first gear is an acute angle, so that when a shoe is stretched, the welt of the shoe cannot be extruded and deformed, and the whole shoe stretcher can be placed conveniently by means of the generated angle.

Description

technical field [0001] The invention relates to the technical field of shoe stretchers, in particular to a shoe stretcher.

[0002] Shoes are a necessity for each of us to wear on our feet to resist the cold, prevent punctures and cuts, and protect our feet. Different types of shoes such as leather shoes, sports shoes, cloth shoes, and slippers are what people need. However, in the process of buying shoes, people sometimes choose the wrong size, resulting in shoes that are too small, or shoes that are too large due to the growth of their own feet. It is small, and the shoes are squeezed and uncomfortable when worn, so it is necessary to use a shoe expander to expand the shoes to meet the needs, but there are still certain defects in the existing shoe expander. The rod and the whole are in a straight layout, so that the existing shoe expander cannot be applied to the shoes of the middle and high state, and can only realize the adjustable stretch function of the forefoot part of the shoe, and cannot realize the adjustable stretch function of the heel part. Its scope of use is greatly reduced, for this reason, a kind of shoe tree is proposed
