A spiral elastic anti-slip strip 32 is provided in the mounting groove 315. The elastic anti-slip strip 32 can not only improve the anti-slip effect of the handle 3, but also improve the comfort of the handle 3. The spiral mounting groove 315 facilitates the stable installation of the elastic anti-slip strip 32, and prevents the elastic anti-slip strip 32 from sliding along the length direction of the handle body 31 after being subjected to excessive force.
[0045] At least two groups of spiral mounting grooves 315 are provided on the outside of the handle body 31. The mounting grooves 315 are combined to form a multi-thread structure. Elastic anti-slip strips 32 are respectively provided in the mounting grooves 315. The elastic anti-slip strips 32 with a multi-thread structure are convenient for dispersing the force of each elastic anti-slip strip 32, so as to avoid excessive force on the handle 3 causing the elastic anti-slip strips 32 to slide in the mounting grooves 315. In this embodiment, two groups of spiral mounting grooves 315 are provided on the outside of the handle body 31.
[0046] Preferably, both ends of the mounting groove 315 are provided with annular connecting grooves 316, and the connecting grooves 316 surround the outer periphery of the grip body 31.
