Work.

具体的，如图3所示，驱动单元31被构造为电机，传动单元32位于支撑壳体15内，电机的电机轴穿过支撑壳体15与传动单元32连接，以实现电机驱动传动单元32转动。Specifically, as shown in FIG. 3 , the drive unit 31 is configured as a motor, the transmission unit 32 is located in the support housing 15 , and the motor shaft of the motor is connected to the transmission unit 32 through the support housing 15 , so as to realize that the motor drives the transmission unit 32 turn.

再具体的，传动单元32包括第一齿轮321、联动齿轮323、传动元件324和第二齿轮322，电机穿过支撑壳体15的第二底板153后与第一齿轮321同轴转动，联动齿轮323包括同轴转动的输入齿轮3231和输出齿轮3232，输入齿轮3231与输出齿轮3232间通过连接轴连接，输入齿轮3231和输出齿轮3232间隔的设置在连接轴上，连接轴与支撑壳体15转动连接。第一齿轮321与输入齿轮3231啮合，以便将电机的驱动力传递至输出齿轮3232，输出齿轮3232与第二齿轮322啮合，用于进一步将电机的驱动力传递给第二齿轮322；传动元件324与第二齿轮322同轴转动，传动元件324用于与工具头200的传动连接件4耦合，用于最终通过传动元件324将电机的驱动力传递给工具头200，以驱动工具头200工作。More specifically, the transmission unit 32 includes a first gear 321 , a linkage gear 323 , a transmission element 324 and a second gear 322 . The motor rotates coaxially with the first gear 321 after passing through the second bottom plate 153 of the support housing 15 , and the linkage gear 323 includes a coaxially rotating input gear 3231 and an output gear 3232, the input gear 3231 and the output gear 3232 are connected by a connecting shaft, the input gear 3231 and the output gear 3232 are arranged on the connecting shaft at intervals, and the connecting shaft rotates with the support housing 15 connect. The first gear 321 meshes with the input gear 3231 to transmit the driving force of the motor to the output gear 3232, and the output gear 3232 meshes with the second gear 322 to further transmit the driving force of the motor to the second gear 322; the transmission element 324 Coaxially rotating with the second gear 322 , the transmission element 324 is used for coupling with the transmission connecting piece 4 of the tool head 200 , for finally transmitting the driving force of the motor to the tool head 200 through the transmission element 324 to drive the tool head 200 to work.

优选的，传动元件上配置有至少一个施力面，传动连接件上配置有与施力面对应的受力面；当工具头安装到工具头安装部上时，传动元件的施力面与传动连接件的受力面配合，以使得手持式工具机为工具头提供驱动力时，传动元件转动且施力面能够向受力面施加推力，以推动传动连接件带动工具头工作。Preferably, the transmission element is provided with at least one force-applying surface, and the transmission connecting piece is provided with a force-receiving surface corresponding to the force-applying surface; when the tool head is mounted on the tool head mounting portion, the force-applying surface of the transmission element is the same as the force-applying surface.

可以理解的是，通过改变第一齿轮321、第二齿轮322以及联动齿轮323的尺寸，能够实现对电机31输出的转速进行加速或减速，以适应不同的工具的不同需求。此外，通过设置联动齿轮323能够实现对电机31输出的转速进行多级减速，使得传动件324输出较小的转速n，如果直接将第二齿轮322与输出齿轮3232啮合，为了使传动件324获得相同的转速n，需要将输出齿轮3232的直径设置为较大的尺寸，导致传动组件32在水平方向上的尺寸较大，不方便操作者操作，本实施例通过设置联动齿轮323能够有效减小动力组件在水平方向上的尺寸，减小传动组件32的体积，便于操作者操作。It can be understood that by changing the dimensions of the first gear 321 , the second gear 322 and the interlocking gear 323 , it is possible to accelerate or decelerate the output speed of the motor 31 to meet different requirements of different tools. In addition, by setting the interlocking gear 323, the output speed of the motor 31 can be decelerated in multiple stages, so that the transmission member 324 outputs a smaller rotation speed n. If the second gear 322 is directly meshed with the output gear 3232, in order to make the transmission member 324 obtain For the same rotational speed n, the diameter of the output gear 3232 needs to be set to a larger size, resulting in a larger size of the transmission assembly 32 in the horizontal direction, which is inconvenient for the operator to operate. In this embodiment, the linkage gear 323 can be set to effectively reduce the The size of the power assembly in the horizontal direction reduces the volume of the transmission assembly 32, which is convenient for the operator to operate.
