The invention discloses a control handle for a swash plate type variable displacement piston pump. The control handle comprises a handle rack, a handle lever and a position sensor. The position sensor is mounted on the handle rack, can be triggered by the handle rack when the handle rack is positioned in a middle-position groove and is connected to an alarm device. The control handle has the advantages that an angle of a swash plate of the piston pump can be driven by a shifting block via a stay of the piston pump to be changed when the control handle lever moves in a tap-position slide groove, the position sensor can be triggered when the handle lever is positioned in the middle-position groove, the angle of the swash plate of the swash plate type variable displacement piston pump is zero at the moment, lamplight display effects can be realized by the alarm device, trigger signals are not generated when the handle lever is positioned in an advancing groove or a retreating groove, an engine cannot be started, and accordingly the problem of starting potential safety hazards can be solved.
