PET LEASH CONTROL DEVICE

A leash control device includes: a housing including a top cover and a bottom cover rigidly connected to the top cover; a cable wheel including a cylindrical outer ring, the cylindrical outer ring being configured for a leash cable to be wounded on an outer surface of the cylindrical outer ring; a button having a cylindrical member configured on an upper portion of the button and a base configured on a lower portion of the button, the cylindrical member being configured to be extended through a central hole of the top cover; and a compression string configured to bias the button in an upward direction to cause the button to engage with the cable wheel; wherein: when a pressing force is applied to the cylindrical member of the button to counter an upward biasing force of the compression string and no pulling force is applied to the leash cable, the button is configured to be pressed down and disengaged from the cable wheel, and after the button is disengaged from the cable wheel, the cable wheel is configured to rotate freely about a central axis when a pulling force is applied to the leash cable, causing the leash cable to unwind and extend out of the leash control device; and when the button is not pressed down and a pulling force is applied to the leash cable, a vertical post configured on an upper surface of the bottom cover interferes with an underside surface of the base of the button, preventing the button to be pressed down.
