[0007] An adjustment component, the adjustment component includes a connecting sleeve, a first screw and a second screw. The inner wall of the connecting sleeve is provided with a thread. The first screw and the second screw are respectively screwed to the two ends of the connecting sleeve. The toe tightening block is fixed to the other end of the first screw, and the heel tightening block is fixed to the other end of the second screw. Rotating the connecting sleeve can make the toe tightening block and the heel tightening block move away from or closer to each other.
[0008] The beneficial effects of the utility model are as follows: the shoe size adjustment device is placed in the shoe, the toe tightening block is arranged corresponding to the toe, the heel tightening block is arranged corresponding to the heel, the connecting sleeve is rotated, the connecting sleeve is screwed with the first screw and the second screw to drive the toe tightening block and the heel tightening block to move away from each other, the toe tightening block tightens the toe, and the heel tightening block tightens the heel, so that the shoe is expanded from the inside.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, the connecting sleeve has a plurality of planes cut out on its outer wall along its axial direction to increase friction.
[0011] Furthermore, the outer contour of the cross section of the connecting sleeve is a regular hexagon.
[0012] Furthermore, the lengths of the first screw rod and the second screw rod are equal, and the length of the connecting sleeve is equal to the sum of the lengths of the first screw rod and the second screw rod.
[0013] Furthermore, the connecting sleeve is divided into a first connecting section and a second connecting section along its axial direction, the threads in the first connecting section and the threads in the second connecting section are in opposite directions, the first screw is threadedly connected to the threads in the first connecting section, and the second screw is threadedly connected to the threads in the second connecting section.
[0014] Furthermore, the toe tightening block and the heel tightening block are made of rubber. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 The utility model is a structural schematic diagram of a shoe enlarging device provided by the utility model.
[0016] In the accompanying drawings, the components represented by the reference numerals are listed as follows:
[0017] 1-shoe tip tightening block, 2-heel tightening block, 3-adjusting component, 31-connecting sleeve, 32-first screw rod, 33-second screw rod. DETAILED DESCRIPTION
[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0019] The utility model aims to provide a shoe enlarging device to solve the problems existing in the prior art, and can appropriately enlarge the shoes so that the shoes can be properly worn, thereby delaying waste.
[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
