[0061] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0062] Combination Figure 1 and Figure 2 A pet traction device comprises: a shell 1; a turntable 2, which is rotatably installed in the shell 1, and a plurality of blocks 21 are circumferentially arranged on the turntable 2, and a traction rope is wound around the outer side of the turntable 2; a locking device 3, which is installed in the shell 1 and is used to limit the rotation of the turntable 2 for a long time; a temporary locking device 4, which is installed on the inner side of the turntable 2 and is used to limit the rotation of the turntable 2 for a short time; a rope collecting device 5, which is installed in the shell 1 and movably connected to the turntable 2, and is used to drive the turntable 2 to rotate to retract the traction rope.

[0063] The locking device 3 fixes the extended length of the traction rope within a set range, and the traction rope no longer automatically retracts and retracts. In scenarios where stable control of the pet is required, such as training, taking pictures, or interacting with other pets, the locking device 3 can provide continuous stable pulling force to ensure that the pet is within the controllable range of the owner. The locking device 3 makes the traction device safe and stable.

[0064] When the owner needs to temporarily fix the length of the rope (such as crossing the road, encountering other pets or pedestrians, etc.), the temporary locking device 4 can quickly control the rotation of the turntable to control the length of the traction rope, thereby ensuring the safety of the pet. In an emergency, the temporary locking device 4 can quickly respond to the owner's operation to help the owner control the pet's behavior in time. The temporary locking device 4 makes the traction device flexible and convenient.

[0065] Combination Figures 2 to 4, wherein the locking device 3 includes: a lock member 6, which is slidably connected to one side of the shell 1, and the front end of the lock member 6 has a driving portion 61, the driving portion 61 is curved, and the driving portion 61 is placed in the shell 1; a lock core 7, which is hinged in the shell 1, and the rear end of the lock core 7 is provided with a locking portion 72, and the front end of the lock core 7 movably abuts the driving portion 61; an elastic member 31, which is a spring or a disc spring or a silicone block, the elastic member 31 is installed in the shell 1, and the elastic member 31 is movably connected to the front end of the lock core 7, so that the locking portion 72 has a tendency to rotate toward the turntable 2, the inner side wall of the shell 1 is provided with a mounting groove 1, and the lower side of the front end of the lock core 7 is formed with a mounting groove 2, and the two ends of the elastic member 31 are respectively placed in the mounting groove 1 and the mounting groove 2 to realize the installation of the elastic member 31.

[0066] When the lock member 6 is pushed forward in the shell 1, the driving part 61 moves forward and the front end of the lock core 7 is subjected to the elastic force of the elastic part 31, so that the front end of the lock core 7 slides on the driving part 61 or the front end of the lock core 7 is directly separated from the driving part 61, so that the lock core 7 rotates under the action of the elastic part 31, so that the locking part 72 abuts against the block 21 of the turntable 2, thereby limiting the rotation of the turntable 2, and finally achieving the control of the extension length of the traction rope.

[0067] When the lock member 6 is pushed backward in the shell 1, the driving portion 61 abuts against the front end of the lock core 7 and overcomes the elastic force of the elastic member 31, so that the lock core 7 rotates, thereby separating the locking portion 72 from the block 21 of the turntable 2, and finally enabling the turntable 2 to rotate so that the length of the traction rope can be extended or retracted into the shell 1.

[0068] Combination Figure 2 and Figure 3 The rear end of the lock element 6 has a limiting portion 62, and the rear end of the lock core 7 has a limiting portion 71; when the locking portion 72 of the lock core 7 abuts against the block 21 of the turntable 2, the limiting portion 62 is movably pressed against the limiting portion 71 to limit the rotation of the lock core 7, thereby ensuring that the rotation of the turntable 2 is limited, and preventing the turntable 2 from rotating too fast when the traction rope is quickly extended out of the housing 1, causing the block 21 to collide with the locking portion 72, causing the lock core 7 to transmit, thereby affecting the abutment stability between the block 21 and the locking portion 72.

[0073] In this solution, blocks 3 81 are provided on both sides of the end of the button 8, blocks 2 22 are provided on both side walls of the turntable 2, and the turntable 2 is placed between the blocks 3 81. When the button 8 is pressed, the blocks 3 81 on both sides of the button 8 abut against the blocks 2 22 on both sides of the turntable 2, thereby limiting the rotation of the turntable 2. The blocks 3 81 provided on both sides of the button 8 are more secure and stable than the blocks 3 81 provided on one side, so as to prevent the blocks 3 81 from breaking.

[0074] Combination Figures 2 to 4A sliding groove 13 is provided in the housing 1, and mounting openings 131 are provided on both sides of the sliding groove 13. A connecting piece 42 is clamped in the mounting opening 131 of the sliding groove 13, and a through hole 82 is provided on the button 8; when the button 8 is movably placed in the sliding groove 13, the middle part of the connecting piece 42 is placed in the through hole 82, and the two ends of the elastic piece 41 respectively abut against the inner walls of the connecting piece 42 and the through hole 82, so that the button 8 has a tendency to move toward the center of the turntable 2.

[0075] Combination Figures 2 to 4 A convex ring 24 is provided on the side wall of the turntable 2, the outer side of the convex ring 24 is connected to the block 1 21, the inner side of the convex ring 24 is connected to the block 22, and the locking portion 72 of the lock core 7 movably abuts against the outer side of the convex ring 24, and the block 3 81 of the button 8 movably abuts against the inner side of the convex ring 24. The convex ring 24 is used to strengthen the structural strength of the block 1 21 and the block 2 22 to prevent the block 1 21 and the block 2 22 from breaking. At the same time, the convex ring 24 limits the excessive rotation of the locking portion 72 of the lock core 7 and the excessive penetration of the button 8 into the housing 1.

[0076] Combination Figures 2 to 4 The rope collecting device 5 includes: a coil spring 51, which is installed in the spring cavity of the shell 1; a rotating shaft 52, the lower section of which extends into the coil cavity and is movably connected to the coil spring 51, and the upper section of the rotating shaft 52 is connected with a bearing, and the bearing is installed in the bearing cavity of the shell 1; a gear 53, which is installed on the rotating shaft 52; a gear ring 23 is provided on the inner side of the turntable 2, and the gear 53 is meshed with the gear ring 23; the rotating shaft 52 is driven to rotate by the coil spring 51, and the rotating shaft 52 drives the gear 53 to rotate, thereby driving the turntable 2 to rotate in the shell 1.
