Specifically, the locking member 72 is a crank structure, the shell 1 arranges an outlet corresponding to a position of the locking member 72, a top of the locking member 72 extends out of the shell 1 through the outlet, to facilitate the pet owner to operate. The sliding member 73 comprises a slider body 731, a cantilever 732, a first limiting portion 733 and a second limiting portion 734. Wherein the slider body 731 passes through the braking assembly 6, and both ends of the slider body 731 are arranged on the shell 1, the first limiting portion 733 is a square block shaped structure, the first limiting portion 733 is arranged at a bottom of the slider body 731. In an implementation method, the first limiting portion 733 is a trapezoidal structure, to ensure a strength of the first limiting portion 733. The cantilever 732 is arranged on both sides of the slider body 731, and the sliding member 73 is rotatably connected with the locking member 72 through the cantilever 732. The second limiting portion 734 is arranged on the slider body 731 and located on a side of the slider body 731 close to the storage bin 5. When the sliding member 73 moves laterally toward the braking assembly 6 for a certain distance through the locking member 72, that is, when the locking member 72 is pushed to move the sliding member 73 toward the braking assembly 6, the first limiting portion 733 will abut against the braking assembly 6, to keep the braking assembly 6 in the braking state, that is, now the locking assembly 7 is in the locked state. It should be noted that, when the sliding member 73 is in an initial position (the locking assembly 7 is in an unlocked state), the second limiting portion 734 is applied to restricting the storage bin 5 from being opened, that is, If the storage bin 5 is opened, it will have an interference with the second limiting portion 734. Then, when the sliding member 73 moves laterally toward the braking assembly 6 through the locking member 72, the second limiting portion 734 will release the restriction to the storage bin 5, that is, now the storage bin 5, after being opened, will not have an interference with the second limiting portion 734.

Specifically, the first groove 111 and the third groove 121 are a limiting groove of the sliding member 73, one end of the slider body 731 penetrates the first groove 111, another end of the slider body 731 penetrates the third groove 121 after passing through the braking member 61, to complete an installation of the sliding member 73. Wherein, under a limiting effect of the first groove 111 and the third groove 121 to a limiting body, when the locking member 72 drives the sliding member 73 to move, it is possible to restrict the slider body 731 to move laterally toward the braking assembly 6, and after the sliding member 73 moves laterally for a certain distance toward the braking assembly 6 through the locking member 72, the first limiting rib 735 is engaged together with the second groove 112. At this time, the locking assembly 7 has already been in a locked state. In the present embodiment, the first limiting rib 735 and the second groove 112 are engaged together, which is able to prevent the slider body 731 from moving, to ensure a stability of the locked state of the locking assembly 7. More specifically, both a surface of the first limiting rib 735 and a side of the first supporting portion 11 close to the first limiting rib 735 are both a circular arc surface, to facilitate the first limiting rib 735 sliding into the second groove 112 when the slider body 731 moves.

Specifically, a top end of the braking member 61 extends out of the shell 1 through an opening on the shell 1, and the braking member 61 is arranged adjacent to the locking member 72, while a height of the braking member 61 extending out of the shell 1 is greater than that of the locking member 72 extending out of the shell 1, so the pet owner will not touch the locking member 72 during using, convenient for the pet owner to operate with one hand.
More specifically, in an implementation method, the first elastic member 63 may be a compression spring, the compression spring is arranged in the accommodation cavity 62 of the braking member 61, and one end of the compression spring abuts against the top of the braking member 61 (the compression spring is installed in the braking member 61, and a height of an inner space of the braking member 61 is smaller than a length of the compression spring, so the compression spring is compressed), another end will abut again the shell 1. The first through hole 64 is a square shaped through hole, the first through hole 64 penetrates the braking member 61 along a width direction of the braking member 61, and connects to the accommodation cavity 62, while the sliding member 73 penetrates through the first through hole 64. When pressing the braking member 61, the braking member 61 squeezes the compression spring, after the compression spring is compressed, the braking member 61 moves downward for a certain distance, so the third limiting portion 65 on the braking member 61 will be able to touch the rotating wheel 2, thus being able to restrict the rotating wheel 2 from a further rotation, while the braking assembly 6 is in a braking state. Then when the braking member 61 is in the pressed state and is pressed to an end, the third limiting portion 65 of the braking member 61 has already touched the rotating wheel 2. In the braking state, a top of the braking member 61 goes down and approaches the locking member 72, making a hand be able to control a position of the locking member 72. If the sliding member 73 is driven to move toward the braking member 61 by the locking member 72, the first limiting portion 733 arranged on the slider body 731 will also move toward the braking member 61, since the braking member 61 has already generated a relative displacement downwards, thus the braking member 61 will not interfere with the first limiting portion 733, that is, the first limiting portion 733 is able to enter the first through hole 64 before abutting against the braking member 61. Now if the hand releases the braking member 61 or reduces a downward pressure on the braking member 61. then the braking member 61 will move upward under an action of the compression spring, however when moving until touching the first limiting portion 733, no more movement can be continued, now the braking member 61 still maintains a contact with the rotating wheel 2, preventing the rotating wheel 2 from rolling, but keeping in the braking state.
It should be noted that, since the rotating wheel 2 has a plurality of teeth (generally it is 8), under an action of an external tension and a force of a coil spring, the rotating wheel 2 will roll, the traction rope wound on the rotating wheel 2 will be reversed under a drive of the coil spring. Due to an angular difference between the teeth of the rotating wheel 2, after the braking member 61 is pressed down, it will stay between the teeth, thus the teeth will be blocked by a rear end of the third limiting portion on the braking member 61, and no longer being able to continue moving.

Specifically, the switch assembly 55 is able to control the bin cover 52 to be opened or closed. The connecting portion 53 is a rotating arm of the bin cover 52, the shell 1 has a second rotating shaft 14 arranged, the bin cover 52 is rotatably connected to the second rotating shaft 14 on the shell 1 through the connecting portion 53, and the fourth limiting portion 54 is a block shaped structure, while the fourth limiting portion 54 is arranged on the connecting portion 53. When the locking assembly 7 is in the unlocked state, the fourth limiting portion 54 is facing normally the second limiting portion 734. Therefore, if the bin cover 52 is opened at this time, the fourth limiting portion 54 will generate an interference with the second limiting portion 734, thus when the locking assembly 7 is in the unlocked state, the storage bin 5 cannot be opened, while the locking assembly 7 is in the locked state, the sliding member 73 moves toward the braking member 61 a certain distance, now the fourth limiting portion 54 and the second limiting portion 734 have been already staggered, therefore, if the bin cover 52 is opened at this time, the fourth limiting portion 54 and the second limiting portion 734 will not generate the interference.
It is understandable that when the bin cover 52 is in the opened state, if the locking member 72 is pushed to move, the locking block will drive the sliding member 73 to move, but the sliding member 73, due to being blocked by the fourth limiting portion 54, cannot continue to move, the locking member 72 cannot continue to move either, the first limiting portion 733 will still within a interference range of the braking member, the braking member is still unable to move, and the braking member is still in the braking state, that ensures that when the bin cover 52 is not closed, the locking assembly 7 cannot be released from the locked state, and the braking assembly 6 cannot be released from the braking state.
It should be noted that, shown as

Further, the protrusion 554 comprises a first section 5541 and a second section 5542, the first section 5541 connects to the bin body 51, the second section 5542 connects to the first section 5541. The button 552 further comprises a buckle 5522 and a slot 5523, the buckle 5522 is arranged on a bottom of the button 552, the slot 5523 is arranged on an end of the button 552 away from the base 551. Specifically, the buckle 5522 close to the slot 5523 has a first curved surface 5524 arranged on one end, the second section 5542 has a first inclined surface 5544 arranged, the first section 5541 has a second curved surface 5543 arranged, and the button 552 has a second inclined surface 5525 arranged. In one implementation method, the elastic member may be a compression spring, when it is needed to close the bin cover 52, that is, during a process of engaging the bin cover 52 and the bin body 51, or that is, during a process of the buckle 5522 slides downwards along the first inclined surface 5544 through the first curved surface 5524 and abuts against the second section 5542, and the slot 5523 passes through the protrusion 554 to make the protrusion 554 be accommodated in the slot 5523, the second inclined surface 5525 on the button 552 and the second curved surface 5543 on the first section 5541 is able to prevent the button 552 and the protrusion 554 from colliding and interfering, making the button 552 be able to slide down along the first inclined surface 5544 and abut against the second section 5542. It should be noted that, a surface normal of the second curved surface 5543 is outward, If the button 552 is touched, the button 552 will move outward, opposite to a movement of the first curved surface 5524 on the first inclined surface 5544, and the button 552 is not able to move.
When closing the storage bin 5, that is, during a process of closing the bin cover 52 and the bin body 51, when the bin cover 52 is closed to a very small size, the button 552 contacts with the second section 5542, the button 552 generates a retraction under an action of an reaction force, making the bin cover 52 be able to be closed, and the compression spring be compressed after being forced. After the protrusion 554 is accommodated in the slot 5523, the buckle 5522 abuts against In the second section 5542, the external force received by the compression spring disappears, and the compression spring rebounds and drives the button 552 to rebound, making the button 552 and the protrusion 554 be buckled together tightly, thereby ensuring the bin cover 52 and the bin body 51 being in a closed state and not easy to detach. In addition, the switch assembly 55 has a compact structure, and the elastic member is arranged transversely to the bin cover 52, which is able to greatly reduce an overall thickness of the shell 1.
