The light-sensing type hand-block combination switch according to claim 4, wherein: one end of the U-shaped optocoupler fixed on the main PCBA board is a light emitting end, and the other end of the U-shaped optocoupler is a light receiving end; in the initial state, the light emitting end keeps emitting light, the receiving end receives light, and the switching mechanism judges and identifies that the handle is in the initial state; when the handle is pushed forward to drive the swing arm to move backwards around the shaft, the swing arm drives the shifting post to drive the blocking piece to move linearly along the guide groove on the middle shell, when the blocking piece moves to the middle of the optocoupler and blocks light emitted by the light emitting end, the light receiving end cannot receive the light, and the switch mechanism judges and identifies a gear corresponding to the handle; otherwise, the handle is pulled back and is driven the swing arm and around the axle forward motion, and the swing arm is stirred and is dialled the post and drive the separation blade along the guide way linear motion on the mesochite, moves in the middle of the opto-coupler and blocks the light that light-emitting end sent when the separation blade, and light receiving end can not receive light, and switching mechanism judges and discerns the fender position that the handle corresponds.

6. An optical induction type hand-drive combination switch according to claim 1, 2, 3 or 5, wherein: the function of the combination switch is arranged as follows:

the left handle realizes left-right lane changing and steering functions through shifting in the front-back direction; the left handle realizes the turning on of the overtaking lamp by lifting up, the left handle realizes the turning on of the high beam by pressing down, and the middle part is in a light-off state;

7. The light-sensing type hand-block combination switch according to claim 4, wherein: the function of the combination switch is arranged as follows:

an A/M gear switching function is integrated with a key at the outer end part of the right handle, and an Rm peristaltic mode, a Dm peristaltic mode and an E, P gear switching function are arranged on the knob; the shifting button is provided with D, N, R gear function;

8. The light-sensing type hand-block combination switch according to claim 6, wherein: and character marks corresponding to functions are arranged on the handle between the key and the knob, between the knob and the toggle button and between the toggle button and the combination switch body.
