The following describes the present invention in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, a shift handle with a snap spring structure according to an embodiment includes a shift handle 1, an insertion hole 11 adapted to a shift lever 2 is formed in a lower end surface of the shift handle 1, and the shift lever 2 is inserted into the insertion hole 11 in an upward sliding manner; a handle frame groove 12 extending along the circumferential direction is concavely formed in the lower portion of the side face of the gear shifting handle 1, a U-shaped steel wire clamp spring 3 is arranged in the handle frame groove 12, the steel wire clamp spring 3 comprises a middle section and straight edge sections connected to two ends of the middle section respectively, the handle frame groove 12 is matched with the steel wire clamp spring 3 so as to accommodate the steel wire clamp spring 3, groove sections corresponding to the straight edge sections of the handle frame groove 12 and the steel wire clamp spring 3 are formed into straight groove sections, the straight edge sections of the steel wire clamp spring 3 are elastically attached to the bottom walls of the corresponding straight groove sections, and the jack 11 is located between the two straight groove sections; the vertical distance from the bottom wall of any straight groove section to the central axis of the jack 11 is smaller than the radius of the jack 11, so that a crevasse is formed on the inner wall of the jack 11 and is formed into a clamping hole 13, a clamping spring groove 21 is concavely formed in the position, corresponding to the clamping hole 13, on the gear shifting lever 2, and the corresponding straight edge section of the steel wire clamping spring 3 is clamped into the clamping spring groove 21 through the clamping hole 13, so that the gear shifting handle 1 and the gear shifting lever 2 are fixed relatively.

According to the gear shifting handle with the clamp spring structure, the clamp spring structure is designed at the lower end of the gear shifting handle 1 to achieve assembly and positioning between the gear shifting handle 1 and the gear shifting rod 2, and the clamp spring structure is hidden inside by utilizing the space of the insertion hole 11, so that the space is saved, and the appearance is more attractive; utilize the elasticity of steel wire jump ring 3 to realize quick assembly and dismantlement, only joint hole 13 position runs through to jack 11, does not influence the structural strength that handle 1 used of shifting.

During the assembly, arrange steel wire jump ring 3 in handle skeleton groove 12, when handle 1 that will shift carries out the joint downwards with gear level 2, rely on the elasticity of steel wire jump ring 3 itself, realize inserting in the twinkling of an eye steel wire jump ring 3 in the position reconversion of joint hole 13 and radially fall into in jump ring groove 21 to realize gear level 2 and the relatively fixed between the handle 1 of shifting. In order to prevent the steel wire clamp spring 3 from being separated from the handle frame groove 12 in the transverse direction, a decorative cover is further arranged outside the gear shifting handle 1 to wrap the whole handle frame groove 12 and is used for preventing the steel wire clamp spring 3 from being separated. It can be understood that, in order to ensure the detachability of the shift handle 1 when it is upward, the vertical distance from the bottom wall of the straight groove section to the center of the insertion hole 11 is smaller than the radius of the insertion hole 11, and the difference between the radius of the insertion hole 11 and the vertical distance from the bottom wall of the straight groove section to the center of the insertion hole 11 may correspond to the diameter of the wire clamp spring 3.

Please refer to fig. 1-5, wherein the width of the clamp spring slot 21 is adapted to the diameter of the wire clamp spring 3, and chamfers are formed on the clamp spring slot 21 along the length direction of the shift lever 2.

Thus, the gear shifting handle 1 is pulled out forcibly and upwards through the chamfer of the clamp spring groove 21, and quick disassembly is realized. In practice, the chamfer has a slope of 70 °.

A groove 22 is formed in the top end of the shift lever 2 in a downward direction along the length direction of the shift lever 2, and a clamping block 14 is convexly arranged on the inner wall of the insertion hole 11 at a position corresponding to the groove 22; the latch 14 is located in the recess 22 to prevent rotation between the shift knob 1 and the shift lever 2.

In this way, the shift lever 2 is prevented from rotating within the insertion hole 11, while also contributing to further strengthen the fixing strength between the shift knob 1 and the shift lever 2.

The groove 22 is an equal-width groove body, the width of the fixture block 14 is gradually increased along the length direction of the gear shift lever 2 from bottom to top, and the width of the top end of the fixture block is matched with the width of the groove 22. The outer circumference of the top end of the gear shift lever 2 and the top of the groove 22 are provided with round chamfers.

Thus, in actual assembly, the fixture block 14 is in a conical shape with a large top and a small bottom, and the top end of the fixture block forms interference fit with the groove 22, so that the structural strength of clamping is improved.

Wherein the top of the groove 22 is provided with a round chamfer.

Thus, the top of the groove 22 is prevented from scratching the latch 14.

Wherein, the outer periphery of the top end of the gear shift lever 2 is provided with a round chamfer.

In this way, the top end of the gear shift lever is prevented from scratching the inner wall of the insertion hole 11 of the gear shift handle.

The position of the groove 22 is arranged right above the clamp spring groove 21.

Thus, during assembly, the gear shift lever 2 is clamped into the gear shift handle 1 along the position of the groove 22, and the steel wire clamp spring correspondingly falls into the clamp spring groove 21.

Two clamp spring grooves 21 are formed in the position, corresponding to the straight edge section of the steel wire clamp spring 3, of the gear shifting lever 2; the two clamp spring grooves are radially symmetrical; two radially symmetrical grooves 22 are formed in the top end of the gear shifting rod 2 downwards along the length direction of the gear shifting rod 2, and clamping blocks 14 are convexly arranged on the inner wall of the insertion hole 11 corresponding to the positions of the grooves 22.

Therefore, the forward and reverse problems of the gear shifting handle 1 and the gear shifting rod 2 do not need to be considered during assembly, and the assembly efficiency is improved.

The length of the straight edge section clamped in the clamp spring groove 21 is greater than that of another straight edge section, and the vertical distance from the bottom wall of the straight groove section corresponding to the another straight edge section to the axis of the insertion hole 11 is greater than the radius of the insertion hole 11.

Thus, the free end of the straight groove section corresponding to the straight edge section can not extend through the side surface of the shift handle 1, and the strength of the shift handle 1 at the position where the handle skeleton groove 12 is formed is improved.

Finally, it is noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
