[0054] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] This embodiment provides a quick-release assembly, which includes a first component and a second component. The first component has a fixed shaft, and the second component has a fixed cavity into which the fixed shaft is inserted. The quick-release assembly also includes a locking mechanism for locking the fixed shaft within the fixed cavity. When the locking mechanism is in an unlocked state, the first component and the second component are detachably connected.

[0056] This embodiment also provides a traction device using the above-described quick-release assembly. This traction device can be used as a component of a children's vehicle (such as the running bike described below). In this case, the first component can be a waistband assembly, and the second component can be a pull rod, enabling quick installation and removal of the waistband assembly.

[0057] This embodiment also provides a stroller, which includes a traction device employing the aforementioned quick-release assembly. Specifically, the stroller in this embodiment is as follows: Figures 1 to 11 The treadmill shown.

[0058] Reference Figures 1 to 11The treadmill includes a treadmill body 1 and a traction device. The traction device includes a pull rod 2 and a waistband assembly 3. The pull rod 2 is connected to the treadmill body 1, and the waistband assembly 3 is connected to the front end of the pull rod 2. The rear end of the waistband assembly 3 is provided with a fixed shaft 31, which has a neck 311 with a small outer diameter. The front end of the pull rod 2 has a fixing cavity 21 for receiving the fixed shaft 31. A locking mechanism for locking the fixed shaft 31 in the fixing cavity 21 is provided between the front end of the pull rod 2 and the rear end of the waistband assembly 3. The locking mechanism has a locked state and an unlocked state. The locking mechanism includes two locking plates (a first locking plate 41 and a second locking plate 42), two buttons (a first button 43 and a second button 44), and two elastic elements (a first elastic element 45 and a second elastic element 46). The first locking plate 41 is slidably disposed on the front end of the pull rod 2 along a radial direction perpendicular to the axis of the fixed shaft 31. The second locking plate 42 is slidably disposed on the front end of the pull rod 2 along a radial direction perpendicular to the axis of the fixed shaft 31. The first locking plate 41 and the second locking plate 42 are respectively located on opposite sides of the neck 311 of the fixed shaft 31, and the first button 43 and the second button 44 are also respectively located on opposite sides of the neck 311 of the fixed shaft 31. The first locking plate 41 has a first end face that contacts the neck 311 and a second end face that abuts against the first button 43. The first end face is an arc-shaped surface adapted to the neck 311. The second locking plate 42 has a third end face that contacts the neck 311 and a fourth end face that abuts against the second button 44, wherein the third end face is also an arc-shaped surface adapted to the neck 311. Optionally, the first locking plate 41 is L-shaped, and the surface area of ​​the first end face is larger than the surface area of ​​the second end face; the second locking plate 42 is also L-shaped, and the surface area of ​​the third end face is larger than the surface area of ​​the fourth end face. The first button 43 abuts against the first locking plate 41. The first button 43 has a first operating portion 431 exposed on the pull rod 2. The first operating portion 431 and the first locking plate 41 are located on opposite sides of the fixed shaft 31. Specifically, the first end face and the second end face of the first locking plate 41 both face the first operating portion 431, and the second end face is in contact with the first operating portion 431. The second button 44 abuts against the second locking plate 42. The second button 44 has a second operating portion 441 exposed on the pull rod 2. The second operating portion 441 and the second locking plate 42 are located on opposite sides of the fixed shaft 31. Specifically, the third end face and the fourth end face of the second locking plate 42 both face the second operating portion 441, and the fourth end face is in contact with the second operating portion 441. A first elastic member 45 is located between the first locking plate 41 and the second button 44. The first elastic member 45 has a tendency to make the first locking plate 41 slide towards the neck 311. The second elastic element 46 is located between the second locking piece 42 and the first button 43, and the second elastic element 46 has a tendency to make the second locking piece 42 slide toward the neck 311.Specifically, the first elastic element 45 is a compression spring, with one end of the first elastic element 45 pressing against the first locking plate 41 and the other end of the first elastic element 45 pressing against the second button 44; the second elastic element 46 is also a compression spring, with one end of the second elastic element 46 pressing against the second locking plate 42 and the other end of the second elastic element 46 pressing against the first button 43.

[0059] like Figures 4 to 9 When the locking mechanism is in the locked state, it locks the fixed shaft 31 of the waistband assembly 3 into the fixed cavity 21 of the pull rod 2. At this time, the first end face of the first locking piece 41 contacts the neck 311 of the fixed shaft 31, and the third end face of the second locking piece 42 also contacts the neck 311 of the fixed shaft 31; the second end face of the first locking piece 41 contacts the first operating part 431, and the fourth end face of the second locking piece 42 contacts the second operating part 441; the entire first locking piece 41 and the entire second locking piece 42 are located on opposite sides of the neck 311 of the fixed shaft 31. When the locking mechanism is in the locked state, both the first elastic element 45 and the second elastic element 46 are in their initial state. Figures 10 to 11 The locking mechanism changes from the locked state to the unlocked state, and the front end of the pull rod 2 is detachably connected to the rear end of the waistband assembly 3. Specifically, pressing the first button 43 and the second button 44 simultaneously pushes the first locking plate 41 and the second locking plate 42 away from the fixed shaft 31. The first elastic element 45 and the second elastic element 46 change from their initial state to a deformed state, providing a restoring force for the first locking plate 41 and the second locking plate 42. When the locking mechanism is in the unlocked state, the fixed shaft 31 can disengage from the fixed cavity 21.

[0060] The treadmill in this embodiment has the following advantages over the prior art: the waistband component of the treadmill can be quickly disassembled and installed, allowing the waistband component to be quickly separated from the treadmill body, making it convenient for the user to quickly detach from the treadmill body.
