The rectangular straight leaf spring B and the rectangular straight leaf spring C are arranged on two sides of the center of the rectangular straight leaf spring A.
The rectangular straight leaf spring B and the rectangular straight leaf spring C are fixedly connected to two sides of the center of the rectangular straight leaf spring A.
The utility model discloses a working process: when the buffer type tool connecting rod is installed on an electric or pneumatic tool and needs to loosen or tighten a screw, instant impact force can be transmitted to the rectangular straight piece spring in the tool connecting rod firstly, the rectangular straight piece spring transmits the impact force to the screwdriver head, so that the impact force directly transmitted to the screwdriver head by the electric, pneumatic or manual tool is buffered, the screwdriver head or the screw is reduced from being damaged, the spring piece automatically changes the distortion degree along with the impact force, and the elastic distortion automatically resets when the work is finished.
The utility model discloses a theory of operation is: the tool extension rod is divided into an extension rod front section and an extension rod rear section, a buffer structure formed by rectangular straight springs is arranged in the middle of the extension rod, and the extension rod front section and the extension rod rear section are connected and fixed into a whole by a connecting sleeve and a C-shaped clamp spring without influencing the axial displacement of the extension rod front section and the extension rod rear section during working. The rectangular straight spring is used for absorbing or converting the impact force of an electric tool, a pneumatic tool or a manual tool to have a buffer function.
The utility model has the advantages that: the novel extension rod has the advantages of being scientific in design, simple in structure, convenient to use, capable of overcoming the technical defects of the extension rod of the existing tool, capable of overcoming the structural defects of the extension rod of the conventional tool in the aspect, and capable of improving working efficiency and saving use cost. When the electric, pneumatic or manual tool is used, after the buffer type tool extension rod is connected, the service life of the bit or the screw is longer.
