The first connecting half ring 210 is connected to the first handle loop 220 at both ends, and the second connecting half ring 310 is connected to the second handle loop 320 at both ends. There is a risk of breakage due to the large force at the connection. Therefore, the reinforcement part 260 is provided to increase the connection contact area between the first connecting half ring 210 and the first handle loop 220, and to increase the connection contact area between the second connecting half ring 310 and the second handle loop 320. This can increase the strength of the connection and improve the strength and durability of the handle. Specifically, the width of the connecting half ring is 8-12 mm, and the maximum width of the reinforcement part 260 is 4-6 mm.
