Technical Field

The utility model relates to a pet pulling equipment technical field, concretely relates to pet tractor of easy locking of haulage rope.

Background

To prevent pets from wandering, owners often equip the pet with a retractor. At present, the pet retractors sold in the market have various structural forms, and generally comprise a shell, a rotating disc arranged in the shell and a traction rope wound on the rotating disc, wherein a revolving body for automatically withdrawing the traction rope is arranged between the shell and the rotating disc, and the pet retractors of the traditional structure have the following defects:

1. when the pet is frightened or is ready to attack other people and suddenly runs away, the traction rope wound on the reel can be quickly pulled out, and the owner can not brake the inner reel of the tractor in time to pull the pet, so that safety accidents are easy to happen.

2. Even though some retractors are provided with buttons for braking the turntables, when the turntables are braked and locked, the traction ropes pulled by pets can cause impact on the turntables and the buttons, and the impact damage can be easily caused to the buttons, so that the locking is disabled.
