Title:
SHOCK-ABSORBING GUIDING STRUCTURE FOR EXTENSION TUBE
Document Type and Number:
WIPO Patent Application WO/2018/040493
Kind Code:
A1
Abstract:
A shock-absorbing guiding structure (100) for an extension tube comprises an inner tube (1), an outer tube (2), and a shock-absorbing member (3). The inner tube (1) is slidably sleeved into the outer tube (2). The shock-absorbing member (3) is provided at an end surface of one end of the inner tube (1). An edge of the shock-absorbing member (3) engages with an outer edge of the inner tube (1) and abuts against an inner wall of the outer tube (2), such that when the inner tube (1) extends outwardly, the shock-absorbing member (3) turns downwards to reduce a friction force, and when the inner tube (1) retracts inwardly, the shock-absorbing member (3) remains slidably abutting against the inner wall of the outer tube (2), thereby realizing shock-absorbing. The shock-absorbing guiding structure (100) for an extension tube has a simple structure and good buffing performance, and can protect hands from being clamped.
