Description

Technical Field

[0001] The utility model relates to the field of pet traction devices, in particular to a telescopic pet traction device. Background Art

[0002] Existing pet leashes usually consist of a harness or collar fixed to the pet, a leash ring, and a rope adjustment device. Pet leashes can help owners better control the pet's range of activities and prevent the pet from running around or getting lost. Through the leash, owners can also better train their pets to obey instructions and maintain good behavior. At the same time, pet leashes usually need to be light and easy to carry, so that owners can take their pets out for activities at any time.

[0003] Existing retractable leashes are divided into two types: handle-mounted leashes and ring-shaped leashes. The gripping parts are all made of hard plastic materials, which causes a large pulling force when the pet rushes forward when gripping, thus causing the handle to squeeze and press on the hand; and the relatively single gripping method also limits the user's usage methods and scenarios. At the same time, almost all retractable traction rope products use the key pin to interfere with the groove of the pulley spring sideways for braking; for example, the "Retractable Locking Mechanism and Pet Traction Rope Using Such Mechanism" with application number ZL201720504066.3: "The reel 2 rotates, and the spiral spring 25 stores deformation force. At this time, the rope body 14 is released, and the rope body 14 will be retracted into the reel 2 due to the deformation force of the spiral spring 25. At the same time, the retractable button 31 is pressed, and the ratchet 311 on the retractable button 31 clamps the ratchet 21 on the reel 2, clamping the rope body 14." However, this braking method is subject to the spacing and width of the groove body. When the key pin is not inserted into the slot during the rapid sliding process, there is a risk of damage and failure to brake. Therefore, a new type of easy-to-hold pet traction device is urgently needed on the market. Utility Model Content

[0039] When the pet suddenly runs out, the user can choose to quickly press the dynamic lock button with the index finger, so that the dynamic lock button drives the elastic rotating arm to approach and lock the winding mechanism. If the lock needs to be maintained, the thumb can be used to move the state lock button to the constant lock position at the same time to enter the constant lock state; the user can also choose to directly use the thumb to move the state lock button to enter the constant lock state. The two buttons do not conflict with each other when used and can work independently. If the traditional latch method is used for locking, the traction rope and the winding mechanism will move rapidly under the pull of the pet, and the latch may collide with the ratchet and be damaged. The present application uses an elastic rotating arm to lock the winding mechanism. The blocking teeth of the elastic rotating arm are screwed in from one side to engage with the limit teeth. The elastic rotating arm will not be completely locked, which can effectively reduce the damage to the elastic rotating arm.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
