The limiting groove 404 is formed on the outer periphery of the secondary handle 405. The limiting strip 403 is mounted on the lower inner sidewall of the main handle 401. The limiting strip 403 and the limiting groove 404 correspond one-to-one and limit the... The outer periphery of the positioning bar 403 is slidably connected to the inside of the limiting groove 404. The lower end of the threaded rod 402 is threadedly connected to the middle of the auxiliary handle 405. The upper part of the threaded rod 402 is rotatably connected to the upper part of the main handle 401. The locking component 406 is installed on the upper part of the main handle 401. The lower part of the locking component 406 is set at the upper end of the threaded rod 402. A protective cover 3 is fixedly connected to the lower outer periphery of the main handle 401. The lower part of the protective cover 3 is set on the upper part of the fixing plate 1. An anti-slip rubber sleeve is provided on the outer periphery of the main handle 401.

[0022] Specifically, the main handle 401 slides inside the outer periphery of the secondary handle 405 and is limited by the limiting strip 403 and the limiting groove 404, so that the main handle 401 cannot rotate relative to the secondary handle 405. The locking component 406 drives the threaded rod 402 to rotate, thereby causing the threaded rod 402 to drive the main handle 401 to extend and retract relative to the secondary handle 405, thereby adjusting the length of the telescopic mechanism 4, which is convenient for people with different usage habits.

[0023] In the embodiment, the locking assembly 406 comprises a connecting plate 4061, a spring 4062, a connecting cylinder 4063, a clamping groove 4064, a sliding groove 4065, a sliding block 4066 and a clamping block 4067.
