摘要： A rear-moving, self-propelled working machine includes a main machine and a handle device. The main machine includes a moving assembly and a motor for driving the moving assembly. The handle device is connected to the main machine and includes an operation member, a connecting rod assembly, a housing, a sensing device, and a trigger assembly. The operation member includes a grip for a user to hold. The connecting rod assembly includes a first connecting rod connected to the main machine. The sensing device is used for sensing a thrust applied to the handle device to drive the rear-moving, self-propelled working machine. The trigger assembly is capable of applying a force to the sensing device when the grip receives the thrust. The trigger assembly is connected to the connecting rod assembly, and the sensing device is connected to the operation member.

摘要： A walk-behind self-propelled working machine includes a main body, an operation switch, and a handle device. The main body includes a moving assembly and a drive motor. The operation switch is connected to the drive motor. The handle device is connected to the main body and includes an operation member, a connecting rod, and a sensing device. The operation member includes a gripping portion for a user to hold. The connecting rod is connected to the main body. The sensing device is configured to sense a thrust that is applied to the handle device to drive the walk-behind self-propelled working machine and further includes a pressure sensor and a pressing member. When the gripping portion receives the thrust, the pressing member applies a force along a preset straight line to the pressure sensor to drive the pressure sensor to deform.
