For ease of understanding, the left side of the utility model is Figure 2 The position of the middle command mechanism 50, on the right side is Figure 2 The middle bracket 10 is located at the front side. Figure 2 The middle part indicates the location of the reset assembly 40, and the rear side is Figure 2 The other side opposite to the front side.

[0027] like Figure 1-Figure 8 As shown, a highly integrated control handle includes a bracket 10, in which a drive mechanism 20, a gear feedback mechanism 30, a reset assembly 40 and a command mechanism 50 are arranged. The drive mechanism 20 provides a driving force by generating a displacement, and the driving force provided by the drive mechanism 20 controls the operation of an external device through the command mechanism 50, which constitutes the basic mechanism of the present utility model.

The rocker arm 23 is concentrically arranged with the first joint 21 and the second joint 22. The rocker arm 23 is used to control the rotation of the first joint 21 and the second joint 22. The first joint 21 and the second joint 22 are arranged in a cross-shaped manner to limit the movement direction of the rocker arm 23. Furthermore, the first joint 21 and the second joint 22 are provided with a hollow track groove for limiting the movement direction of the rocker arm 23. The rocker arm 23 is provided with a control part extending out of the bracket 10. The first joint 21 and the second joint 22 are arranged in a cross-shaped manner, and the movement trajectories of the two are controlled by the same rocker arm 23. Under the premise of ensuring the gear adjustment function, the occupied space is reduced.

[0029] A toggle portion 24 is provided at both ends of the first joint 21 and the second joint 22 respectively. The toggle portion 24 includes an extension portion extending downward from both ends of the first joint 21 and the second joint 22 and a column portion protruding outward. Specifically, the toggle portion 24 is integrally formed at both ends of the first joint 21 and the second joint 22.

[0030] A group of gear feedback mechanisms 30 and a group of reset components 40 are respectively arranged at both ends of the first joint 21 and the second joint 22. The gear feedback mechanisms 30 on both sides of the first joint 21 are arranged in opposite directions, and the gear feedback mechanisms 30 on both sides of the second joint 22 are arranged in opposite directions. The gear feedback mechanisms 30 include a gear member 31, a mounting frame 32, and an elastic retaining member; the gear member 31 is rotatably arranged in the bracket 10, and a gear portion 312 is arranged on the side of the gear member 31 facing the mounting frame 32.

The driving mechanism 20 drives the gear member 31 to rotate through the toggle portion 24 to switch the gear wheel 33 to abut against different positions of the gear portion 312; the reset component 40 is used to drive the gear member 31 and the driving mechanism 20 to reset. When the gear member 31 is reset, it will drive the toggle portion 24 to return to the original position, thereby driving the corresponding joint (the first joint 21 and / or the second joint 22) to return to the original position.

[0031] As the control handle switches gears, the gear wheel 33 will collide with the gear slot 3121 of the gear portion 312 on the gear member 31, and the generated vibration is transmitted to the operator through the rocker rod 23 as an in-position signal, thereby playing the role of feeding back gear information.

[0032] In some embodiments, the shift member 31 has a connection portion A311 and a shift portion 312.

[0033] In some embodiments, the reset component 40 is a tension spring, one end of which is connected to the shift member 31, and the other end of the tension spring is connected to the bracket 10, so that the shift member 31 has a tendency to abut against the toggle portion 24 under the action of the tension spring. On the one hand, when the rocker arm 23 drives the first joint 21 and / or the second joint 22 to rotate, the corresponding toggle portion 24 can immediately drive the corresponding shift member 31 to swing. On the other hand, when the reset component 40 drives the shift member 31 to reset, the shift member 31 can immediately drive the corresponding toggle portion 24 and the joint to reset.

The mounting frame 32 can maintain the gear wheel 33 in contact with the gear portion 312 under the action of the elastic retaining member, and can also drive the mounting frame 32 to return to its original position when the gear member 31 is reset.

[0036] In some embodiments, the shift member 31 has a bending portion 313, which is disposed between the connecting portion A311 and the shift portion 312. The toggle portion 24 abuts against the bending portion 313 of the shift member 31, and the bending portion 313 acts as a limit to ensure that the toggle portion 24 can contact the shift member 31 more stably.

[0037] When the control handle is moved backward from the initial state, the toggle portion 24 on the left side of the first joint 21 drives the corresponding gear member 31 to rotate, that is, drives the gear member 31 on the right side to rotate, and the gear wheel 33 begins to switch to the first gear gear slot 3123.

When the control handle is moved backward from the initial state, the toggle portion 24 on the left side of the first joint 21 drives the corresponding gear member 31 to rotate, that is, drives the gear member 31 on the left side to rotate, and the gear wheel 33 begins to switch to the first gear gear slot 3123. As the control handle continues to move backward, the gear wheel 33 will gradually switch to the second gear gear slot 3126.

Specifically, Figure 8As shown, the trigger protrusion 548 on the forward gear cam member 542 is arranged on the right side of the forward gear cam member 542, and the trigger protrusion 548 on the reverse gear cam member 543 is arranged on the left side of the reverse gear cam member 543.
