The handle 2 includes a handle body 21, a leg 22 having one end fixed to the handle body 21, and a locking structure 23 rotatably connected to the handle body 21. As shown in fig. 4, the vertical direction is axial, the handle body 21 is annular, the top ends of the legs 22 are connected to the middle of the inner peripheral wall of the handle body 21, and the locking structure 23 is rotatably connected to the bottom end of the handle body 21.

A clamping fit structure is arranged between the outer peripheral surface of the gear shift lever 1 and the inner peripheral surface of the supporting leg 22 so as to limit the axial direction and the circumferential direction of the supporting leg 22. A guide structure is arranged in the clamping matching structure.

When the locking structure 23 is rotated to the predetermined locking position in the clamping state of the snap fit structure, as shown in fig. 4, the leg 22 is radially restrained. Specifically, the locking structure 23 is provided with a top block 232, and the top block 232 is rotated to the outer side of the leg 22 in the radial direction to limit the leg 22 in the radial direction. When the locking structure 23 rotates to the preset unlocking position, the supporting leg 22 has a radial moving space, so that the supporting leg 22 can swing under the guide of the guide structure after receiving the axial force, and the axial limit of the clamping matching structure on the supporting leg 22 is released.

Further, as shown in fig. 1, the snap-fit structure includes an axial slide 11 provided on an outer peripheral surface of the shift lever 1, a stopper groove 12 provided on the axial slide 11, and a stopper protrusion 221 provided on an inner peripheral surface of the leg 22. Preferably, the two axial ramps 11 are symmetrically arranged on the gear shift lever 1. The axial slideway 11 is used for guiding the axial sliding of the supporting leg 22, and the axial slideway 11 can circumferentially limit the supporting leg 22, that is, the supporting leg 22 cannot rotate relative to the shift lever 1 after entering the axial slideway 11. The retaining groove 12 is adapted to snap fit with the retaining protrusion 221, as shown in fig. 4, to axially retain the leg 22. Through the setting of axial slide 11, can lead the axial push-and-pull motion of handle 2, guarantee that spacing arch 221 and spacing recess 12 can the quick joint target in place.

Furthermore, the limiting groove 12 and the limiting protrusion 221 are respectively provided with a guiding surface along the axial pulling-out direction of the handle 2, and the guiding surfaces form a guiding structure. As shown in fig. 4, the axial direction of the handle 2 is upward, and the upper ends of the limiting groove 12 and the limiting protrusion 221 are respectively provided with a guide surface, specifically, the rod guide surface 13 on the limiting groove 12 and the leg guide surface 222 on the limiting protrusion 221. The guide surface is inclined with respect to the axial direction and gradually moves away from the center axis of the shift lever 1 in the pull-out direction. As shown in fig. 4, the lever guide surface 13 and the leg guide surface 222 are each gradually distant from the center axis of the shift lever 1 in an upward direction.

In the state that the handle 2 is assembled on the gear shift lever 1, if the handle 2 needs to be disassembled, the locking structure 23 is rotated to the preset unlocking position, the handle 2 is pulled upwards, the leg guide surface 222 is attached to the lever guide surface 13 and continuously moves upwards, and in the process of moving upwards, the leg 22 is pushed outwards along the radial direction by the lever guide surface 13, so that the limiting protrusion 221 is pushed out of the limiting groove 12, and the axial limiting of the handle 2 is released.

The guide surfaces are arranged on the limiting groove 12 and the limiting protrusion 221, so that the stability of the handle 2 in the pulling-out motion can be improved. Of course, in other embodiments, as shown in fig. 13, only one of the limiting groove 12 and the limiting protrusion 221 may be provided with a guiding surface as a guiding structure, and the other one may be provided with a vertical axial ridge to match with the guiding surface, or the leg 22 may be pushed to swing when the handle is pulled out.

Further, as shown in fig. 6 to 8, a positioning block 231 is disposed on the locking structure 23, and an elastic gear curved surface 211 is disposed on the handle body 21.

When the positioning block 231 is located in the unlocking gear slot, the locking structure 23 is in the preset unlocking position. When the positioning block 231 is located in the locking gear groove 215, the locking structure 23 is in the preset locking position.

During the movement of the positioning block 231 from the unlocking range slot toward the locking range slot 215, the positioning block 231 is kept from the pressure of the resistance slope 214, i.e., the force by which the positioning block 231 slides on the locking range slot 215 to the latter position is greater than or equal to the force by which it slides to the former position. The resistance inclined surface 214 can increase the difficulty of the positioning block 231 in disengaging from the locking gear groove 215, so that the positioning block 231 can disengage from the locking gear groove 215 to enter the resistance inclined surface 214 only by applying a larger circumferential force, and the locking reliability can be ensured.

In addition, the handle body 21 is provided with two centrally symmetrical gear curved surfaces 211 to lock the rotational stability of the structure 23.

Further, the resistance inclined surface 214 sequentially includes a resistance inclined surface and a resistance plane perpendicular to the axial direction in a direction from the unlocking range groove to the locking range groove 215 in the circumferential direction, and the resistance inclined surface continuously protrudes toward the positioning block 231 in the direction from the unlocking range groove to the locking range groove 215 in the circumferential direction. In the process that the positioning block 231 moves towards the locking gear groove 215 on the resistance inclined surface 214, the pressure applied to the positioning block 231 continuously increases on the resistance inclined surface, and then the positioning block 231 slides into the locking gear groove 215 along the resistance plane, and due to the arrangement of the resistance plane, after the positioning block 231 moves to the resistance plane from the locking gear groove 215 due to an unexpected situation, as the resistance plane does not have a circumferential guiding function, as long as the positioning block 231 does not receive an external circumferential force any more, the locking structure 23 and the handle body 21 can be kept in a relatively static state.

Further, as shown in fig. 8, the unlock range groove includes a start range groove 212 and an intermediate range groove 213, and the intermediate range groove 213 is butted in a circumferential direction between the start range groove 212 and the resistance slope 214.

When the positioning block 231 is located in the initial position groove 212, the positioning block 231 is opposite to the tip of the initial position groove 212, the positioning block 231 is attached to the wall surface of the initial position groove 212 far from the middle position groove 213, and has a gap with the wall surface of the initial position groove 212 near the middle position groove 213, in the orientation shown in fig. 8, when the positioning block 231 is located in the initial position groove 212, the positioning block 231 is attached to the left side wall surface of the initial position groove 212, and has a gap with the right side wall surface, specifically forming an included angle, so that the right side wall surface of the initial position groove 212 provides a relatively gentle guiding effect, and the positioning block 231 can easily enter the middle position groove 213 from the initial position groove 212.

Further, referring to fig. 8, the middle shift groove 213 and the locking shift groove 215 are both angular grooves. When the positioning block 231 is located in the middle position groove 213, the positioning block 231 is opposite to the tip of the middle position groove 213 and the wall surface of the middle position groove 213 is attached to each other, and when the positioning block 231 is located in the locking position groove 215, the positioning block 231 is opposite to the tip of the locking position groove 215 and the wall surface of the middle position groove is attached to each other. The positioning block 231 can be more reliably circumferentially restrained when it is located in either the intermediate gear groove 213 or the locking gear groove 215.

Wherein, in actual processing, the extension trend of gear curved surface 211 each department can be designed through the emulation according to the demand of locking force and unblock power, and it is little specifically to satisfy the torque of locking to guarantee easy to assemble, and the unblock torque is big, in order to guarantee can not dismantled easily. In addition, the surface of the positioning block 231 is preferably set to be a curved surface, and the positioning block 231 has certain elasticity and can be deformed so as to prevent the gear curved surface 211 from being damaged during the movement of the positioning block 231. As shown in fig. 7, a deformation space is provided on a side of the positioning block 231 away from the shift position curved surface 211, and a space below the positioning block 231 is shown to accommodate the deformed positioning block 231.

Further, referring to fig. 8, the curved gear surface 211 is disposed on an axial end surface of the handle body 21, and the positioning block 231 is disposed on an axial end surface of the locking structure 23, so as to facilitate processing. Specifically, the handle body 21 and the locking structure 23 are concentric ring structures.

Of course, in other embodiments, the handle body 21 can be rotatably sleeved outside the locking structure 23, and the curved gear surface 211 and the positioning block 231 are respectively disposed on the inner circumferential surface of the handle body 21 and the outer circumferential surface of the locking structure 23. Alternatively, the positioning block 231 may be provided on the handle body 21, and the curved shift surface 211 may be provided on the lock structure 23.

Further, referring to fig. 9, 11 and 12, a clamping groove 216 is disposed at an axial end of the handle main body 21, a buckle 233 detachably clamped in the clamping groove 216 is disposed on the locking structure 23, a space for the buckle 233 to slide circumferentially is disposed in the clamping groove 216, and the locking structure 23 can be conveniently assembled on the handle main body 21 by the cooperation of the buckle 233 and the clamping groove 216. The positioning block 231 is located in the initial gear groove 212 when the latch 233 is just slid into the slot 216.

In assembling the locking structure 23, as shown in fig. 11, the latch 233 is aligned with an entrance of the slot 216, and then the locking structure 23 is rotated to rotate the latch 233 into the slot 216, as shown in fig. 12, to achieve axial spacing between the locking structure 23 and the handle body 21, and further, the latch 233 can be rotated in the slot 216 to allow circumferential relative movement with a determined axial positional relationship between the locking structure 23 and the handle body 21.

Furthermore, the legs 22 are elastic members, and when the handle 2 is assembled and disassembled, the legs 22 have enough deformation to smoothly assemble and disassemble the handle 2, so that the service life of the handle 2 needing to be repeatedly assembled and disassembled can be prolonged.
