AI Technical Summary
In existing agricultural unmanned driving equipment, the switching between human and machine collaboration is inconvenient and laborious, and the mode cannot be switched quickly, which poses risks to safety and reliability.
It adopts a shaft-hole coupling-decoupling structure, which utilizes radially rolling steel balls to move between the core sleeve and the bushing. Coupling and decoupling are achieved through the cooperation of the steel balls with the core shaft and bushing. Combined with the frictional self-locking of the return spring and the support seat, it enables quick and convenient human-machine switching.
It enables rapid switching between human-machine collaborative devices, reduces operational resistance, improves system safety and reliability, and ensures rapid takeover of equipment in emergency situations.

Abstract
Claims
1. A shaft-hole coupling-decoupling structure, characterized by: It includes a circumferentially rotatable core sleeve, and a spindle and bushing coaxially arranged inside and outside the core sleeve, respectively; in: The sidewall of the core sleeve is provided with several through holes, and steel balls that can roll radially are provided in the through holes; The mandrel includes an upper section with a smaller diameter and a lower section with a larger diameter. The outer wall of the lower section is provided with an annular groove for the inner part of the steel ball to enter. The inner wall of the bushing is provided with several axial grooves along the circumferential direction for the outer part of the steel ball to enter. In the coupled state, the steel balls roll radially outward and are located in the through hole and axial groove respectively. The circumferentially rotating core sleeve drives the bushing to rotate synchronously through the steel balls. When the core is lifted, the steel balls roll radially inward into the annular groove and through hole, switching to the decoupled state, and the core sleeve and bushing are unlocked.
2. The structure of claim 1, wherein: The upper end of the spindle is connected to a handle that controls the axial movement of the spindle.
3. The post-hole coupling-decoupling structure according to claim 2, characterized in that: It also includes a connector, the lower end of which is fixedly connected to the upper end of the spindle, and the upper end of which is rotatably connected to the handle via a rotating shaft.
4. The structure of claim 2, wherein: It also includes a return spring in a compressed state, with the upper end of the return spring pressing against the lower end face of the bushing top plate and the lower end of the return spring pressing against the upper end face of the lower section of the spindle.
5. The dielectric waveguide-to-coaxial coupler-decoupler structure of any of claims 2-4, wherein: It also includes a support base, which is ring-shaped and located on the upper end face of the bushing top plate; the handle body has a groove corresponding to the side wall of the support base, the groove is embedded in the side wall of the support base to generate friction to prevent it from automatically resetting, thus achieving self-locking; And / or, the support base is made of rubber material.
6. The shaft-hole coupling-decoupling structure according to claim 1, characterized in that: The cross-section of the axial groove is triangular.
7. The hole-coupling / decoupling structure according to claim 1, characterized by: The lower end of the bushing is provided with a limiting gasket for sealing the mandrel and the mandrel.
8. A control handle characterized by: Includes the shaft-hole coupling-decoupling structure as described in any one of claims 1-7.
