[0036] Installation of this embodiment:

[0037] 1) Insert the trapezoidal washer 5 from the inside to the outside into the second mounting hole 22 set at the front end of the handle body 2;

[0038] 2) Move the ear seat from front to back to the middle position of the front fork 21 at the front end of the handle body 2, so that the first mounting hole 13 of the ear seat and the second mounting hole 22 at the front end of the handle body 2 and the through hole of the trapezoidal washer 5 are located on the same axis;

[0039] 3) Pass the rotating shaft 4 from the left side of the handle body 2 through the trapezoidal washer 5, the left front fork 21 of the handle body 2, and the first mounting hole 13 of the ear seat U-shaped piece 12 in sequence from left to right.

[0040] 4) Insert the tension screw 3 from the right side of the handle body 2, from right to left, through the trapezoidal washer 5, the right front fork 21 of the handle body 2, the first mounting hole 13 of the ear seat, and then threadedly connect it with the threaded channel of the rotating shaft 4;

[0041] 5) Insert the spring from the back to the front into the long slot at the rear end of the slider 7; then put the slider 7 and the spring together from the bottom to the top into the second slide slot 24 at the lower end of the handle body 2. At this time, ensure that the countersunk screw through hole 73 below the slider 7 and the positioning hole 25 in the middle of the handle body 2 are on the same axis.

[0042] 6) Insert the button 6 from top to bottom into the positioning hole 25 set at the upper end of the handle body 2; at this time, it is necessary to ensure that the cylindrical 61 threaded blind hole below the button 6, the positioning hole 25 of the handle body 2 and the countersunk screw through hole 73 below the slider 7 are on the same axis;

[0043] 7) Insert the mounting washer 10 into the fastening screw 8 from top to bottom, and then insert the fastening screw 8 and the mounting washer 10 from bottom to top into the countersunk screw through hole 73 below the slider 7 and the positioning hole 25 at the upper end of the handle body 2, and then fasten them to the threaded blind hole of the cylinder 61 below the button 6 to complete the entire installation.

[0044] Working principle:

[0045] 1) Hold the handle body 2 and pull the button 6 horizontally backward. The slider 7 is rigidly connected to the button 6 by the fastening screw 8. Therefore, the slider 7 moves backward synchronously. At this time, the front catch 71 of the slider 7 is separated from the first card slot 111 on the ear seat, and the spring is in a compressed state with a shorter length. At this time, the handle body 2 can rotate counterclockwise around the rotating shaft 4. When the handle body 2 is flipped upward by 80 degrees around the rotating shaft 4 from the horizontal position, release the button 6. The spring releases the pressure and returns to its original length, prompting the slider 7 to move forward. At this time, the front catch 71 of the slider 7 is in close contact with the second card slot 112 of the ear seat, completing the hovering at the second position. Repeat pulling the button 6 backward, and the handle body 2 continues to rotate counterclockwise around the axis. When it rotates 180 degrees from the horizontal position, release the button 6. The spring releases the pressure and returns to its original length, prompting the slider 7 to move forward. At this time, the front catch 71 of the slider 7 is in close contact with the third card slot 113 of the ear seat, completing the folding action.

[0046] 2) When it is necessary to unfold the handle body 2 in the folded state, hold the handle body 2 and gently rotate it clockwise around the rotating shaft 4 without pulling the button 6 at this time. When it rotates to the set card slot position, the handle body 2 makes a pause during rotation. At this time, the slider 7 is in close contact with the card slot on the ear seat, completing the unfolding action.

[0047] 3) When it is necessary to increase the damping during the rotation of the handle body 2 around the rotating shaft 4, tighten the opposed screw 3 and the rotating shaft 4. The opposed screw 3 and the rotating shaft 4 shorten the distance towards the middle, forcing the trapezoidal bosses on the opposed screw 3 and the rotating shaft 4 to increase the radial expansion force on the trapezoidal washer 5, thereby increasing the friction between the trapezoidal washer 5 and the handle body 2. Therefore, the damping feeling of the handle body 2 during the rotation around the rotating shaft 4 is enhanced.

[0048] The above detailed description is a specific description of the feasible embodiments of the present invention. This embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification without departing from the present invention shall be included in the patent scope of this case.
