The present application claims priority to Chinese Patent Application No. 201610318921.1, entitled "A Handle, Tool with Handle, and Method of Connecting a Flexible Material to a Handle", which is filed on May 13, 2016. The entire contents are incorporated herein by reference.

Technical field

The present invention relates to a handle, a tool with a handle, and a method of joining a flexible material to a handle.

Background technique

Common household items or industrial tools on the market are generally made of materials of different materials, such as hammers connected by wooden handles and metal heads, pliers made of plastic handles and metal clips, made of wooden handles or A screwdriver with a plastic handle and a metal bit. These products combine the advantages of different materials and are scientific and reasonable. They can effectively solve various problems in life and thus become widely used and become the basic tools in people's daily life. .

Household items or industrial tools such as cleaning brushes, shoe brushes, mops, feather dusters, brooms, etc., which are made by combining rigid materials with flexible materials, are often used in life. However, existing household articles or tools made by combining rigid materials with flexible materials generally adopt a one-time fixing method. Due to the difference in material between the rigid material and the flexible material, the service life of the flexible material is short, and the flexible material is often bad. However, the rigid material part is still intact. On the other hand, if the one-time fixing method fails, the entire product cannot be used continuously, resulting in serious waste of resources.

Existing household items or tools made by combining rigid materials with flexible materials are also available. Change the mode, but these products are often complicated in structure, inconvenient to disassemble, and the fixed connection is not reliable enough to fully exploit the advantages of rigid materials and flexible materials.

Loofah is a vascular bundle of mature fruit of Cucurbitaceae or Loofah. Also known as Tianluo, loofah, loofah shell, melon, melon, Tianluo, loofah, loofah, Melaleuca or loofah. It has the effect of clearing the vitality, clearing away heat and detoxifying. The mature loofah can be used as kitchen cleaning materials, pure natural products, environmentally friendly and low-carbon, and can clean the kitchen utensils without detergent or with a small amount of detergent. It can be used with flour or baking soda and is popular with consumers. The existing loofah is used for brushing kitchen utensils, and it is often handled by hand. It is both cumbersome and unsanitary. There are other products that fix loofah on the market, but they are often one-piece disposable products, and the fixed structure also has Various defects, such as easy to fall off, the surface area of the loofah brush head is too small, can not be replaced, hard materials are easy to scratch the tableware, etc., can not fully play the advantages of loofah, not only waste materials, but also not economical, not very satisfactory .
