Sleeve ring used for protecting chopping board from cracking

Abstract

The invention particularly relates to a sleeve ring used for protecting a chopping board from cracking. The sleeve ring used for protecting the chopping board from cracking comprises a sleeve ring and a positive and negative tooth tension screw rod, wherein positive teeth and negative teeth are respectively arranged at the two sides of the positive and negative tooth tension screw rod; when the sleeve ring is sheathed at the edge of the chopping board, the positive and negative tooth tension screw rod is respectively twisted into screw caps respectively arranged at the head end and the tail end of the sleeve ring; the two screw caps are pushed forward at the same time under the twisting of the positive and negative tooth tension screw rod, so that the sleeve ring can be contracted; the chopping board is firmly wrapped by the sleeve ring, so that the aim of protecting the chopping board from cracking can be achieved. After the positive and negative tooth tension screw rod is adopted, the tension force of the sleeve ring can be increased to the limit, so that the force of wrapping the chopping board by the sleeve ring is increased accordingly, and the anti-cracking effect is also very remarkable. The sleeve ring is convenient to apply and good in using effect, can be widely applied to chopping boards with various specifications, and has very wide market prospect.

Description

technical field [0001] The invention specifically relates to a collar for protecting an anvil from cracking. technical background [0002] Chopping boards are essential utensils in every family, and some families have 2-3 at the same time. Most of the existing cutting boards are made of wood, and the cutting boards must be fresh and clean after being used. After the cutting boards are cleaned, they are in the natural drying process. Due to the change of the internal stress of the wood, the cutting boards will be dry and cracked over time. , the cracks will become bigger and bigger, and the chopping board will split into several pieces, so this chopping board will become waste products one after another. When the crack is too small, people tend to stick to it. However, many people do not expect that these small cracks are precisely the habitats for harmful germs, and the germs will continue to multiply and expand, and then threaten the health of the whole family.

AI Technical Summary

Problems solved by technology

At present, the collar used to prevent the cutting board from cracking uses a single-sided screw thread to clamp the cutting board by the collar, and the pulling force of the single-sided screw thread is often not large enough when it is used, so that the cutting board wrapped by the collar The strength is also very poor one after another, so even if the cutting board is used with a collar, it will still crack.
