Under an optional implementation mode, the left limiting and clamping assembly and the right limiting and clamping assembly are symmetrically arranged. Because the left limiting and clamping assembly and the right limiting and clamping assembly are respectively used for limiting and clamping a pair of fork heads B of the shifting fork, although the shifting fork formed by the pair of fork heads B and the inner hole part A is of an irregular symmetrical structure, for limiting and clamping the pair of fork heads B, the head end parts of the fork heads B are limited and clamped when the left limiting and clamping assembly and the right limiting and clamping assembly are respectively arranged, therefore, the limiting operation on the pair of fork heads B can be realized through the left limiting and clamping assembly and the right limiting and clamping assembly which are of symmetrical structures, and the shifting fork cannot be influenced due to the irregularity of the shifting fork. In this embodiment, a case where the left and right position limiting clamping assemblies are symmetrical structures is taken as an example.
In detail, for the left and right limiting and clamping assemblies with symmetrical structures, each of the left and right limiting and clamping assemblies comprises a fixed seat 10 fixedly arranged at the top end of the supporting frame 9, a ball stud 7-1 penetrating through the fixed seat 10, a first pressing plate 4-1 and a second pressing plate 4-2 sleeved on the ball stud 7-1 and respectively positioned at two sides of the fixed seat 10, and a first supporting plate 15-1 and a second supporting plate 15-2 respectively arranged on the side end faces of the fixed seat 10 facing the first pressing plate 4-1 and the second pressing plate 4-2 respectively; limiting areas suitable for limiting the fork heads B of the shifting forks are distributed between the first supporting plate 15-1 and the first pressing plate 4-1 and between the second supporting plate 15-2 and the second pressing plate 4-2. It should be noted here that the first pressing plate 4-1 and the second pressing plate 4-2 are respectively disposed on two sides of the fixing base 10, where two sides of the fixing base 10, that is, two side ends of the supporting frame 9, that is, the first pressing plate 4-1 and the second pressing plate 4-2 are actually used for fixing the fork heads B of two shifting forks respectively. And for a pair of fork heads B passing through one shifting fork, the limiting clamping is realized by a first pressure plate 4-1 or a second pressure plate 4-2 respectively included by the left limiting clamping assembly and the right limiting clamping assembly. Wherein, the fixing seat 10 is optionally fixedly connected with the supporting frame 9 by, for example, but not limited to, a first screw 1. The first support plate 15-1 and the second support plate 15-2 may optionally be fixed with the holder 10 by means of, for example, but not limited to, a second screw 14.
The first supporting plate 15-1 and the second supporting plate 15-2 are symmetrically arranged relative to the fixed seat 10; and the first supporting plate 15-1 and the second supporting plate 15-2 are positioned on the part of the fixed seat 10 near the recessed area 11; a ball head fixing end 7-2 at one end of the ball head bolt 7-1 extends out of the outer side, away from the fixing seat 10, of the second pressing plate; and a spherical shoulder nut 6 is sleeved on the part of the ball stud 7-1 extending out of the first pressure plate and departing from the outer side of the fixed seat 10. Namely, the first pressure plate 4-1 and the second pressure plate 4-2 are limited on the ball stud 7-1 through the ball head fixing end 7-2 of the ball stud 7-1 and the spherical shoulder nut 6.

Namely, the looseness of the spring 2 sleeved on the ball stud 7-1 is realized by rotating the spherical shoulder nut 6, and the distance between the first pressing plate 4-1 and the fixed seat 10 and the distance between the second pressing plate 4-2 and the fixed seat 10 can be adjusted. The first supporting plate 15-1 and the second supporting plate 15-2 are symmetrically arranged relative to the fixed seat 10; and the first bearing plate 15-1 and the second bearing plate 15-2 are positioned on the portion of the fixed seat 10 near the recessed area 11. Wherein optionally a flat washer 5 is provided between the end of the spring 2 and the spherical shoulder nut 6.
