Space guiding device

The utility model provides a space guiding device, which relates to the technical field of tactile sticks, and comprises a feeler lever, the bottom of the feeler lever is rotatably connected with a rotating column, the bottom of the rotating column is rotatably connected with a support wheel I, a buffer mechanism is arranged on the upper side of the support wheel I, and the buffer mechanism comprises a sleeve rod and a limiting block. The sleeve rod moves in the axial direction of the probe rod and drives the limiting block to move towards one side of the first supporting wheel, and the auxiliary supporting mechanism is installed on one side of the sleeve rod. According to the device, rotation of the first supporting wheel is blocked by increasing the friction force of the first supporting wheel, rotation of the first supporting wheel is slowed down or the first supporting wheel stops rotating, and therefore the situation that the first supporting wheel accelerates due to inertia on a sudden downhill road sec
