Therefore, by improving the existing five-way shift lever, the utility model adopts the solution that: the inner shaft of the five-direction deflector rod is designed into a spherical structure, the face cover and the shell are assembled to form a circular cavity structure, and the inner shaft rotates in the cavity structure; the guide rods are designed in four directions of the inner shaft to be matched with the guide surfaces of the shell, so that the up-down, left-right toggle operation is realized; the deflector rod and the spherical inner shaft are limited through the hanging buckle, and sliding pressing is realized through the matching of the guide rib and the groove.

The following describes the technical solutions provided by the embodiments of the present utility model with reference to fig. 1 to 4.

Therefore, when the operation rod 3 is shifted towards any group of the limit rods 42, the operation rod 3 drives the sphere 41 to swing in the cavity, the limit rods 42 press the corresponding guide rail 5 to move towards the direction close to the circuit board 6 along with the swinging of the sphere 41, namely, when the operation rod 3 drives the inner shaft 4 to swing, the guide rail 5 is formed to displace in the vertical direction and simultaneously drive the guide rail 5 to move, so that the guide rail 5 presses the corresponding micro switch 13 arranged on the circuit board 6, and the guide rail 5 presses the micro switch 13 to realize functions and operation handfeel.

The toggle implementation switch functions are illustrated as follows: pressing the operating rod 3 drives the direct-pressing push rod, and the direct-pressing push rod presses the micro switch 13 to realize the function and the operation hand feeling; the upper shifting, lower shifting, left shifting and right shifting operation rods 3 are arranged, when the operation rods 3 drive the inner shaft 4 to swing, vertical displacement is formed, meanwhile, the guide rail 5 is driven to move, and the guide rail 5 presses the micro switch 13 to realize functions and operation handfeel. The up, down, left and right toggle of the operating rod 3 drives the sphere 41 to rotate, and when the sphere 41 rotates, the corresponding limiting rod 42 is driven to move, the limiting rod 42 presses the corresponding guide rail 5 to move towards the direction close to the circuit board 6, the guide rail 5 triggers the micro switch 13 to be conducted, and four-way toggle operation of the deflector rod switch is achieved.

In one example, corresponding guiding grooves may be provided to limit guide the guide rail 5 and the guide bar as they move and oscillate vertically.

In addition, the guide rod is accommodated in the guide rod groove 7, and at this time, the guide rod groove 7 limits the horizontal freedom degree of the guide rod to realize vertical swing. The guide rod and the guide rod groove 7, and the guide rail 5 and the guide rail groove 8 are matched with each other to realize vertical movement and swing.
