DETAILED DESCRIPTION

[0017] according to Figures 1 to 6 The specific structure of the utility model is described in detail. The electronic shifter clearance eliminating bushing includes a bushing body 7, a spring accommodating chamber 13 is provided in the bushing body 7, an opening is provided at the upper end of the spring accommodating chamber 13 for facilitating the insertion of the compression spring 15, a toothed plate contact ball head 8 is also provided at the lower end of the bushing body 7, a connecting ring body 9 is also provided at the connection portion between the upper end of the toothed plate contact ball head 8 and the lower end of the bushing body 7, and a plurality of groups of matching clearance eliminating ribs 11 are arranged at equal intervals along the circumference of the ring body on the outer wall of the connecting ring body 9. The transverse cross-section of the matching clearance eliminating ribs 11 is a W-shaped structure with a convex middle and concave sides, and the cross-sectional shape of the middle part is a triangle; the matching clearance eliminating ribs 11 with a W-shaped cross-section are then used to effectively reduce the shift clearance of the shifter and ensure smooth shifting.

[0018] Moreover, a matching elastic clamp 12 for engaging with the inner wall of the handle rod inner hole 4 at the lower end of the shifter handle rod 1 is provided at the upper end of the bushing body 7 of the clearance eliminating bushing 5 and at the opening of the spring accommodating cavity 13.
