Background technique

With the continuous development of my country's economy and the continuous improvement of people's living standards, people's consumption concepts and consumption levels have also undergone great changes and improvements. Under this opportunity, the woodworking tool industry has also developed rapidly. Moreover, my country is a country with a large population, and with the development of urbanization, a large number of rural people pour into cities, which will inevitably lead to the pressure of urban housing, thereby promoting the development of home furnishing manufacturing. And a large number of contradictions between construction and decoration will be very prominent. As the contradiction continues to deepen, this will naturally promote the emergence of "high salaries" in the wood industry. Therefore, the woodworking industry will be one of the neglected industries with development potential.

Since the decoration industry has such good prospects now, the attraction of talents in related industries will also emerge as the times require, and at the same time as the rise of this industry, it has also spawned the development of decoration-related industries, such as carpenters in the same industry. , handicraft enthusiasts, furniture industry, etc. The increase of talents in related industries has directly led to an increase in the market demand for tools required by the industry, and jig saws are particularly important; jig saws are mainly used in woodworking and product prototyping. As well as handicraft production, it is a special tool for professionals in product design, furniture production, model making, etc., and has a large market demand. Convenience and operability also bring a high-quality user experience to users.

However, most of the jig saws on the market currently have relatively simple functions and are very inconvenient to use. When fixing the saw blade, the traditional jig saw usually uses 4mm screws to clamp the top, and the contact area is small, especially the spiral saw blade, which has no pressure. If the friction force is tight, the saw blade will become loose as soon as it is used, and the traditional jig saw uses a straight wooden handle to connect, which is easy to fall off, and the consistency of the wooden handle is poor, which is afraid of sunlight and easy to crack, thus affecting people's normal use. .
