Telescopic mechanism

A telescopic mechanism, comprising:

• a first component;
• and
• a second component telescopically connected to the first component;
• wherein one of the first component and the second component is arranged with a contacting portion, and the contacting portion is configured to resiliently abut against the other one of the first component and the second component;
• wherein the contacting portion comprises an elastic section and a contacting section disposed on a surface of the elastic section, the elastic section tilts toward the other one of the first component and the second component;
• wherein when the contacting portion is in a first state, the other one of the first component and the second component does not abut against the contacting portion, and a first height is defined between the contacting section and a wall of the one of the first component and the second component;
• wherein when the second component is moved relative to the first component to make a portion of the other one of the first component and the second component abut against the elastic section of the contacting portion to bring the contacting portion to change to a second state from the first state, a second height is defined between the contacting section and the wall of the one of the first component and the second component, and the first height is greater than the second height.

A telescopic mechanism, comprising:

• a reinforcement frame comprising a first wall, a second wall and a longitudinal wall connected between the first wall and the second wall, a passage being defined by the first wall, the second wall and the longitudinal wall;
• and
• a bracket detachably mounted to the reinforcement frame, the bracket comprising an extending wall and at least one mounting element;
• wherein one of the reinforcement frame and the bracket is arranged with a contacting portion, the contacting portion comprises an elastic section and a contacting section disposed on a surface of the elastic section, the elastic section tilts toward the other one of the reinforcement frame and the bracket;
• wherein during a process of mounting the extending wall of the bracket in the passage of the reinforcement frame along a first direction, the contacting portion is capable of abutting the other one of the reinforcement frame and the bracket through the elastic section so as to generate a friction resistance;
• wherein when the extending wall of the bracket is mounted in the passage of the reinforcement frame, the at least one mounting element is located outside the passage of the reinforcement frame;
• wherein when the contacting portion is in a first state, the other one of the reinforcement frame and the bracket does not abut against the contacting portion, and a first height is defined between the contacting section and a wall of the one of the reinforcement frame and the bracket;
• wherein when the bracket is moved relative to the reinforcement frame to make a portion of the other one of the reinforcement frame and the bracket abut against the elastic section of the contacting portion to bring the contacting portion to change to a second state from the first state, a second height is defined between the contacting section and the wall of the one of the reinforcement frame and the bracket, and the first height is greater than the second height.
