As shown in fig. 1 to 4, further, in the process of rotating the swing head 510, since the positioning rod 511 is fixedly connected to the swing head 510, the positioning protrusion 512 is fixedly connected to the corresponding positioning rod 511, so that the positioning protrusion 512 is separated from the corresponding positioning hole 310, and performs a circular motion along a side surface of the mounting housing 300 close to the control board 400, when the swing arm 500 and the swing head 510 rotate in opposite directions, and the positioning protrusion 512 is re-inserted into the corresponding positioning hole 310, the swing arm 500 and the swing head 510 are re-positioned to the initial positions again, that is, the re-positioning of the shifter is achieved, so that the accuracy of the re-positioning of the swing arm 500 can be improved.

Furthermore, a protrusion 513 is disposed on the swing head 510, a spring 530 is disposed between the protrusion 513 and the operating lever 200, when people mount the mounting case 300 and the operating lever 200 on the base 100, people need to connect one end of the spring 530 with the protrusion 513, and then connect the other end of the spring 530 with the operating lever 200, so that a certain elastic force is provided between the swing head 510 and the operating lever 200, and thus the swing head 510 always passes through a swing hole (not labeled in the figure) in the rotation process of the swing head 510, and the positioning rod 511 cannot pass through the corresponding through hole 320 in the movement process of the positioning rod 511, and moves from one side of the mounting case 300 to the other side of the mounting case 300.

The shift lever 200 is provided with a shift lever 210 for connecting with the rocker arm 500, the rocker arm 500 is provided with a connecting plate 520 for fastening the shift lever 210, the cross section of the connecting plate 520 is V-shaped, and when the device is installed, people need to clamp the shift lever 210 of the lever 200 into the connecting plate 520, so that when people rotate the lever 200, the shift lever 210 drives the connecting plate 520 and the connecting plate 520 to synchronously rotate.

As shown in fig. 3-6, one end of the operating lever 200 is provided with a toggle plate 220 in an inverted U shape, two side edges of the toggle plate 220 are both arc-shaped, the base 100 is provided with a toggle groove 110, a gear groove 111 for movably mounting the toggle plate 220 is formed in the toggle groove 110, a bottom surface of the gear groove 111 is an arc-shaped surface, and when the operating lever 200 rotates around the rotating column 230, the toggle plate 220 rotates relative to the gear groove 111, and the toggle plate 220 does not contact the bottom surface of the gear groove 111.

Buffer grooves 112 are formed in both ends of the dial groove 110, a buffer block 112a is installed in each buffer groove 112, anti-falling blocks 113 corresponding to the dial plate 220 are arranged at both ends of the bottom surface of the dial groove 110, the plane where the anti-falling blocks 113 are located is perpendicular to the buffer blocks 112a, in the process that the dial plate 220 is driven by the operating lever 200 to rotate around a rotating column 230, and when the dial plate 220 moves towards one end of the dial groove 110, because the dial plate 220 is in an inverted U shape, the cross-sectional shape of the dial plate 220 is the same as that of the anti-falling blocks 113, and the cross-sectional area of the dial plate 220 is larger than that of the anti-falling blocks 113, so that when the dial plate 220 moves towards one end of the dial groove 110, the anti-falling blocks 113 are directly inserted into the dial plate 220, and when the operating lever 200 is displaced and moved due to long-term use or fails to cause the misplacement of manual operation, the anti-falling blocks 113 cannot smoothly enter the dial plate 220, according to the principle, when the gear shifter cannot be smoothly shifted into the gear, people can quickly judge whether the operating lever 200 is dislocated and moved, so that the maintenance of the people is facilitated; when the dial plate 220 moves towards one end of the dial slot 110 quickly, the buffer block 112a is made of rubber material, and the rubber material has certain elasticity, so that the buffer block 112a corresponding to the dial slot 110 can reduce the impact force of the dial plate 220, and the dial plate 220 is prevented from directly impacting the inner wall of the dial slot 110.

The base 100 is provided with a mounting groove 120 for clamping the mounting shell 300, one side surface of the mounting groove 120 is provided with at least two first insertion rods 121, the other side surface of the mounting groove 120 is provided with a plurality of second insertion rods 122 arranged in parallel, the bottom surface of the mounting groove 120 is provided with at least one positioning block 123, the cross-sectional area in the middle of the mounting groove 120 is larger than the cross-sectional area at the two ends of the mounting groove 120, when people mount the mounting shell 300 on the base 100, the two ends of the mounting shell 300 are required to be clamped into the two ends of the mounting groove 120, the first insertion rods 121 are embedded into one end surface of the mounting shell 300, the second insertion rods 122 are embedded into one side surface of the mounting shell 300, and when the mounting shell 300 is completely clamped into the mounting groove 120, the positioning blocks 123 are inserted into the bottom of the mounting shell 300, thus the positioning and mounting of the mounting shell 300 in the mounting groove 120 are realized, and the situation that the mounting shell 300 is displaced during the use or mounting process is avoided, thereby ensuring that the shifter can work properly.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
