Abstract
The invention discloses a tool handle for machining. The tool handle comprises a tool handle shell, a driving mechanism used for driving a tool to reciprocate up and down, and a transmission system used for outputting power to the driving mechanism. The driving mechanism and the transmission system are both arranged in the tool handle shell. The driving mechanism is a crank-sliding block mechanism and comprises a crankshaft, a connecting rod and a sliding block used for mounting the tool, wherein the crankshaft and the sliding block are movably connected to the upper end and the lower end of the connecting rod correspondingly. The tool handle shell is provided with a guiding channel used for mounting the sliding block and guiding up-down reciprocating of the sliding block. When power is input to the driving mechanism through the transmission system, the sliding block of the driving mechanism rapidly reciprocates up and down, linear reciprocating of the tool is achieved, and therefore machining of technical structures such as a mold cavity with the corner being a right-angled part or a key groove is achieved.
