The transmission frame 4 is provided with a slot 5, the end of the shift lever 2 extends into the slot 5, and the slot wall of the slot 5 is provided with an inclined surface 6 for the end face of the shift lever 2 to be abutted against. The frame 4 is also provided with a triangular groove 7 at the position close to the button 3, and the transmission frame 4 also has a linkage portion 8 that protrudes and extends toward the inside of the button 3. The pressing portion of the right-angled triangle, the pressing portion of the right-angled triangle has a hypotenuse portion and a right-angled side portion, the inclined surface 6 is located on the back of the hypotenuse portion, and the triangular groove 7 is opened between the front of the hypotenuse portion and the back of the right-angled side portion, The linkage part 8 is located on the front of the right-angled side part, press the button 3 inward, push the linkage part 8, and make the oblique part on the pressing part press the shift lever 2 to press down, so as to unlock the gear position, on the side of the transmission frame 4 A mounting seat is also installed. The mounting seat has an opening. The opening is equipped with a return spring connected to the button 3. During the process of unlocking the gear, the return spring is compressed. After releasing the button 3, under the process of the return spring, The button 3 is reset, the transmission frame 4 is reset, and the shift lever 2 is reset by the reset mechanism to achieve the purpose of locking. The outer wall of the end of the shift lever 2 extending into the slot 5 has a radially inward opening The concave ring 9 is opened, the outer wall of the end of the shift lever 2 forms a convex step 10 with a radially outward bulge, and the shift lever 2 and the top of the convex step 10 is covered with a lower limit Position sleeve 11, on the shift rod 2 and located at the top of the lower limit sleeve 11 is covered with an upper limit sleeve 12 for fixing and limiting the lower limit sleeve 11, and the shift rod 2 is also threadedly connected with an upper limit sleeve 12 for fixing the lower limit sleeve 11. The limit locking sleeve 13 and the upper limit sleeve 12 are fixed to the lower limit sleeve 11 through several shock absorbing mechanisms with shock absorbing function.

In further detail, several shock-absorbing mechanisms are composed of locking bolts 14, pressing blocks 15, shock-absorbing springs 1 16 and shock-absorbing springs 2 17. The top of the upper limit sleeve 12 is provided with a number of screw holes, and the lower limit sleeve is provided with a plurality of screw holes. The top of the 11 is provided with a number of screw holes 22 that communicate with the corresponding screw holes 1. The screw holes 1 are composed of large-diameter holes 20 and small-diameter screw holes 21 that communicate with each other. 22 are connected with each other, and the screw hole one and the screw hole two 22 are threaded together by the locking bolt 14 so that the upper limit sleeve 12 and the lower limit sleeve 11 are fixed, and the buffer spring one 16 is located in the large diameter hole 20, and the One end of the shock-absorbing spring 16 is supported against the bottom wall of the head of the locking bolt 14, and the other end is supported against the hole wall of the large-diameter hole 20. The pressing block 15 is fixed on the bottom of the locking bolt 14. The second shock spring 17 is located in the second screw hole 22, and one end of the second shock spring 17 is supported against the bottom wall of the pressing block 15, and the other end is supported against the hole wall of the second screw hole 22. When the tightening bolt 14 is tightened, the first cushioning spring 16 and the second cushioning spring 17 are gradually compressed and provide an outward supporting force. When the body passes through a bumpy road section or the engine vibration drives the chassis to resonate, the shift lever 2 and the shift handball are generated. During vibration, firstly, the shift lever 2 is limited to the transmission frame 4 in the shift handball through the upper limit sleeve 12 and the lower limit sleeve 11 in the shock absorbing mechanism and the locking sleeve 13 that fixes and limits the upper two. Specifically, the outer diameter of the upper limit sleeve 12 and the lower limit sleeve 11 is smaller than the transverse groove width of the slot 5 in the transmission frame 4, and the end of the shift lever 2 can be limited to the transmission through the upper limit sleeve 12 and the lower limit sleeve 11. In the frame 4, it is ensured that the shift lever 2 can be well limited in the shift handball when the body is bumped. The setting of the slight distance difference between the widths of the transverse grooves can ensure a certain mobility of the shift lever 2, instead of being in a dead state. The effect can also improve the performance of use.

In addition, when the shift handball is under high-frequency vibration, the first buffer spring 16 supported in the large-diameter hole 20 and the second buffer spring 17 supported against the pressing block 15 can both bring a supporting and buffering effect. At the same time, the pressing block 15 is made of rubber material, which also has a certain cushioning effect, achieving multi-level cushioning force and achieving better cushioning effect.

In further detail, the outer edge of the top of the lower limit sleeve 11 has a raised ring 18 that protrudes axially outward, and the outer edge of the bottom of the upper limit sleeve 12 has a concave ring for the raised ring 18 to be installed. The raised ring 18 There is a rounded corner between the inner peripheral wall of the 12 and the top wall of the lower limit sleeve 11, and the rounded corner is set to reduce the wear of the two when they are assembled. Before the upper limit sleeve 12 and the lower limit sleeve 11 are fixed, the convex ring 18 and the concave ring play the role of positioning, so that the two will not be radially misaligned, achieve accurate positioning, and facilitate the fixed assembly of the two. The sleeve 12 is also provided with a layer of soft pad 19 between the lower limit sleeve 11. The soft pad 19 is laid on the top wall of the lower limit sleeve 11, and the position where the screw hole two 22 is opened is not laid. The soft pad 19 acts as a cushion when the upper limit sleeve 12 and the lower limit sleeve 11 are connected, and can reduce the wear when the upper limit sleeve 12 and the lower limit sleeve 11 are connected.

The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or replace them in similar ways, but will not deviate from the spirit of the present invention or go beyond the appended claims the defined range.
