Impact drill

一种冲击钻

Abstract

本实用新型涉及电动工具,具体说是一种冲击钻,其包括成型有水平空腔的机壳,所述机壳内设有一电机,该电机的转子的一端与设置于机壳内的碳刷连接,所述转子另一端与一齿轮啮合,该齿轮安装在延伸出所述机壳的一输出轴的一端,所述输出轴另一端安装有钻夹头;输出轴所述一端配合设有一冲击块,所述冲击块与一推钮连接;输出轴所述另一端套设有冲击弹簧。本实用新型通过转子带动齿轮驱动输出轴转动,当冲击钻工作时,操作者推动推钮,从而使钻头产生冲击,因此,本冲击钻无需操作者在轴向方向施加很大的轴向力,为操作者提供方便。
The utility model relates to an electric tool, in particular to an impact drill which comprises a casing; the casting is provided with a horizontal cavity; a motor is arranged in the casing; one end of a rotor of the motor is connected with a carbon brush in the casing; the other end of the rotor is meshed with a gear; the gear is mounted at one end, extending from the casing, of an output shaft; a drill chuck is mounted at the other end of the output shaft; an impact block is arranged at the end of the output shaft in a matching manner, and connected with a pushing button; and an impact spring is sleeved at the other end of the output shaft. The gear is driven by the rotor to drive the output shaft to rotate, and when the impact drill is in operation, an operator pushes the pushing button to enable a drill bit to generate an impact force. Therefore, the impact drill provides a convenience for the operator, without applying a great axial force in the axial direction by the operator.
