BACKGROUND
Technical Field
The present disclosure belongs to the technical field of pet products, and specifically to a pet leash device.
Description of Related Art
Pets are friendly friends of human beings, and more and more people begin to keep pets. Taking pets out is a necessary activity for keeping pets. Keeping pets on a leash when outside is of great significance to the safety of other people and pets. When taking a pet out for activities, it is necessary to ensure that the pet has a large range of movement and that the keeper can control the range of movement in a timely manner. Accordingly, a telescopic leash device with a locking function has been devised, which not only ensures that the pet has a large range of movement, but also ensures that the keeper can control the range of movement of the pet. Existing telescopic leash devices usually have an automatic retraction function. Generally, an elastic restoring force of a coil spring is used to drive the reel to rotate and retract the leash. For such leash devices, the retraction speed of the leash is too high, and the leash is likely to rebound and hurt the user, leading to poor safety performance.
