[0055] Specifically, the limiting lock box 6 comprises a shell 61 and limiting members 62 oppositely arranged at two ends of the shell 61, the limiting members 62 are movably connected to the shell 61, the limiting members 62 comprise locking portions 63 and pushed portions 64, when the pushed portions 64 are subjected to external force, the locking portions 63 corresponding to the pushed portions 64 can move towards or away from the shell 61, and the locking portions 63 can be reset when the external force is removed. In this embodiment, the limiting members 62 are slidably connected to the shell 61, the locking portions 63 are used to engage with the limiting portions 411 of the slide 4 to limit the opening of the slide 4, and the pushed portions 64 are used to receive external force to engage or disengage the locking portions 63 with the limiting portions 411 to limit the movement of the slide 4. The external force can be from the limiting strip 74, the limiting strip 74 is provided with a force applying member 741, the force applying member 741 pushes the pushed portions 64 to engage or disengage the locking portions 63 with the limiting portions 411. Preferably, the limiting lock box 6 is in engagement with the limiting portions 411 in the normal state to limit the movement of the slide 4.

[0056] The limiting lock box 6 of this embodiment has simple structure, low error rate and high reliability, the slides 4 are arranged on both sides of the limiting lock box 6, and only one side of the slide 4 can be changed to limit the limiting state of the limiting lock box 6, and the limiting state of the slides 4 on both sides cannot be changed at the same time.

[0057] It can be understood that the limiting lock box 6 can be used not only to limit the slide 4 but also to limit other movable members.

[0058] In some embodiments, the limiting members 62 are two, arranged at two ends of the shell 61, the pushed surfaces 65 of the pushed portions 64 are oppositely arranged, when the external force acts on the pushed surfaces 65, the locking portions 63 corresponding to the pushed surfaces 65 move towards the shell 61. Specifically, the pushed portions 64 are provided with pushed surfaces 65, the pushed surfaces 65 of the two pushed portions 64 are oppositely arranged, the force applying member 741 of the limiting strip 74 is arranged between the two pushed surfaces 65, and the force applying member 741 can only push one of the pushed surfaces 65 when moving. In this embodiment, when the pushed portions 64 are not pushed, the corresponding locking portions 63 engage with the limiting portions of the slide 4 to limit the opening of the slide 4. Such design of this embodiment can prevent the slides 4 on both sides from being opened at the same time.

Specifically, the distance between the two pushed surfaces 65 is greater than the width of the force applying member 741, so that the force applying member 741 does not contact the pushed surfaces 65 on both sides when it is in the middle position. The space between the two sides is the extension space 66, and the stroke of the force applying member 741 is greater than the stroke of the limiting member 62, that is, the limiting member 62 cannot be pushed when the force applying member 741 starts to move, and the limiting member 62 can be pushed to move only after the force applying member 741 moves a certain stroke. Such design can prevent the limiting member 62 from being locked or disengaged with the sliding support 4 when the control handle 3 does not completely switch to the gear position.

[0060] In some embodiments, the two limiting members 62 are arranged in a staggered manner, and the locking portions 63, the pushed portions 64 and the force applying member 741 at both ends are located on a straight line. Specifically, the locking portions 63 at both ends have corners and protrude outwardly from the housing 61, and the limiting members 62 are arranged in a staggered manner, the pushed surfaces 65 at both ends are oppositely arranged, the force applying member 741 is arranged between the two pushed surfaces 65, and the pushed surfaces 65, the locking portions 63 and the force applying member 741 move on the same straight line. Such design is more reasonable in stress and is not easy to slip.

[0061] In some embodiments, a limiting structure is arranged between the locking portion 63 and the pushed portion 64, which can limit the movement of the other limiting member 62 when the pushed portion 64 of one of the limiting members 62 is pushed. Specifically, the movement path of the pushed portion 64 of one of the limiting members 62 overlaps with the locking portion 63 of the other limiting member 62, and the pushed portion 64 can block the movement of the locking portion 63 of the other limiting member 62 when it is pushed.

[0062] In some embodiments, the limiting structure includes a limiting surface one 67 arranged on the pushed portion 64 and a limiting surface two 68 arranged on the locking portion 63, and the movement trajectories of the limiting surface one 67 and the limiting surface two 68 have overlapping portions.
