[0042] Such as Figure 3 - Figure 5As shown, in this embodiment, two symmetrically arranged mounting blocks 400 are integrally formed on the second connecting portion 310. A first sliding groove 410, a second sliding groove 420, and a communicating groove 430 are formed in the mounting block 400. A first slider 440 is slidably mounted in the first sliding groove 410. A spring 441 is installed between the first slider 440 and the mounting block 400. A wedge-shaped clamping block 442 is provided at one end of the first slider 440 away from the spring 441. The inclined surface of the wedge-shaped clamping block 442 faces upward. A blind hole 111 adapted to the wedge-shaped clamping block 442 is formed on the first connecting portion 110. Under the elastic force of the spring 441, the wedge-shaped clamping block 442 is located outside the mounting block 400 and can enter the blind hole 111.

[0043] A second slider 450 is slidably mounted in the second sliding groove 420. One end of the second slider 450 is fixed with a connecting rod 451. The connecting rod 451 extends outside the mounting block 400 and is fixed with a push plate 452.

[0044] The communicating groove 430 connects the first sliding groove 410 and the second sliding groove 420. A gear 460 is rotatably mounted in the communicating groove 430 through a rotating shaft. A first rack 443 is provided on the lower side of the first slider 440. A second rack 453 is provided on the upper side of the second slider 450. The gear 460 is located between the first rack 443 and the second rack 453 and meshes with both the first rack 443 and the second rack 453.

[0045] By adopting the above technical solution, when it is necessary to connect the handle 100 and the hook portion 300, the second connecting portion 310 can be directly aligned with the first connecting portion 110, and the first connecting portion 110 is inserted into the inner ring of the second connecting portion 310. During this process, the wedge-shaped clamping block 442 is resisted by the first connecting portion 110, and the slider is pushed to move in the direction of overcoming the elastic force of the spring 441 until the wedge-shaped clamping block 442 enters the blind hole 111. Then, the second connecting portion 310 is fixed to the first connecting portion 110, thereby connecting the handle 100 and the hook portion 300. When it is necessary to disassemble the handle 100 and the hook portion 300, the push plate 452 can be directly pressed, so that the second slider 450 moves, and the first slider 440 is driven to move toward the spring 441 side through the gear 460, thereby driving the wedge-shaped clamping block 442 to disengage from the blind hole 111. At this time, the handle 100 and the hook portion 300 can be separated.

[0046] Compared with the threaded connection method between the second connecting portion 310 and the first connecting portion 110 in the first embodiment, the quick-release structure in this embodiment is more convenient to operate.

[0047] In this embodiment, two vertically arranged and opposingly disposed guiding bars 311 are provided inside the second connecting portion 310, and a guiding groove 112 adapted to the guiding bars 311 is provided outside the first connecting portion 110.
