Abstract

An electronic control actuator includes a housing, a transmission structure, and a drive unit. The housing includes an installation space. The transmission structure and the drive unit are disposed in the installation space. The drive unit is in transmission connection to the transmission structure. The drive unit includes a drive shaft, a driving gear, and a drive motor. The driving gear sleeves the drive shaft. The transmission structure includes a reduction gear and a transmission assembly. The reduction gear and the transmission assembly are disposed in the installation space. The reduction gear is meshed with the driving gear. The transmission assembly is in transmission connection to the reduction gear. The transmission assembly includes a drive shaft hole. The drive shaft passes through the drive shaft hole and is in transmission connection to the reduction gear.

Abstract

A compound saw includes a base, a housing, a transmission component and a table, the rear end of the table is rotatably connected to the housing, and is engaged with the cutter head through the transmission component, so as to expose the cutter head out of the first cutting slit or out of the second cutting slit when the front end of the table swings upward and downward. The cutter head of the compound saw can be switched between the bench cutting mode and the miter cutting mode. Accordingly, on one hand, the structure for switching between modes is simple and does not require the cooperation of too many parts; on the other hand, the switchover can be realized simply by manually operating the movable bench, without too many operations.
