Description

An easy-to-operate, versatile jigsaw

technical field

The utility model relates to the technical field of jig saws, in particular to an easy-to-operate multifunctional jig saw.

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:

1. The traditional hand-held jig saw consists of a fixed upper arm, a movable lower arm, a handle and a saw blade. The function of the upper and lower arms is to tighten the saw blade to facilitate cutting. A key factor that affects the performance of the jig saw is The respective arm lengths and arm widths of the upper and lower arms, if the arm width is too short, the large plate cannot be cut, but if the arm width is too long, it will greatly affect the operation when processing small plates;

2. Due to the limitation of the length of the arm, for large sheets, the flower saw is often unable to cut. Therefore, in special cases, the operator often removes the saw blade and continues to operate by holding both ends of the saw blade with the fingers of both hands. This is not easy to apply force, and it is easy to hurt the operator, because the saw blade is thin and sharp at both ends, which is easy to scratch the fingers;

3. Although the jig saw is widely used in woodworking, product prototyping and handicraft production, it is not a tool that is used alone to complete the work. In the use and process, there will be many other tools to cooperate with the jig saw , so that the final work can be obtained.
