[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 8 It can be seen that a friction-positioned electric control handle includes a base 1, a rocker 2 is rotatably arranged in the base 1, a handle 3 is arranged on the top of the rocker 2, a rotating shaft 4 is arranged in the base 1 and passes through the rocker 2, the rotating shaft 4 and the rocker 2 are interference fit to achieve synchronous rotation, a magnet 5 is arranged at one end of the rotating shaft 4, a base left cover 6 and a base right cover 7 are respectively arranged on both sides of the base 1, a PCB board 8 is arranged in the left cover 6 of the base, a Hall sensor 9 cooperating with the magnet 5 is arranged in the PCB board 8, a friction block 10 is arranged between the right cover 7 of the base and the rocker 2, the friction block 10 is sleeved on the outside of the rotating shaft 4, and friction force is generated between the friction block 10 and the rotating shaft 4 for frictionally positioning the rotating shaft 4.

[0020] When the utility model is used in a specific way,

[0021] Hold the handle 3 to control it and push the rocker 2 to rotate. The magnet 5 at the end of the rocker 2 cooperates with the Hall sensor 9 to output an angle signal, which is converted into a control signal. The friction block 10 clamps the shaft 4. Without rotating the rocker 2, the friction force rubs the shaft 4 to position it, keeping the angle of the rocker 2 stable, thereby continuously outputting a stable signal.

[0022] A conversion plate 11 is disposed above the base 1 , and a leather cover 12 is disposed above the conversion plate 11 and sleeved on the outside of the rocker 2 for dust prevention.

[0023] An opening 24 is provided on one side of the friction block 10, and the opening 24 is connected by a screw 25. The screw 25 adjusts the friction force of the friction block 10 on the rotating shaft 4. The opening 24 of the friction block 10 is adjusted to a suitable size so that the friction force of the friction block 10 on the rotating shaft 4 is suitable, which can not only realize the rotation of the rotating shaft 4, but also can frictionally position the rotating shaft 4 when it does not rotate.

[0024] The device is divided into Embodiment 1 and Embodiment 2 according to whether micro switches are provided at the front and rear of the base 1.

[0025] Embodiment 1: A turntable 13 is provided at the inner end of the joystick 2, a first notch 14 is opened on one side of the turntable 13, a mid-position microswitch 15 cooperating with the first notch 14 is provided on the side of the base 1, a second notch 16 and a third notch 17 in opposite directions are provided on the other side of the turntable 13, a backward microswitch 18 cooperating with the second notch 16 and a forward microswitch 19 cooperating with the third notch 17 are provided on the side of the base 1.

[0026] When the rocker 2 rotates to the middle position, the first notch 14 cooperates with the middle microswitch 15, and the middle microswitch 15 outputs a corresponding signal. When the rocker 2 is pushed forward, the third notch 17 cooperates with the forward microswitch 19 to output a corresponding signal. When the rocker 2 is pushed backward, the second notch 16 cooperates with the backward microswitch 18 to output a corresponding signal, thereby generating more application methods and extending the scope of use of the electric control handle.

[0027] A sleeve 20 is provided at the bottom of the turntable 13, and a hand wheel 22 is connected to the sleeve 20 via a spring 21. A mid-position hole 23 is provided in the left cover 6 of the base. When the hand wheel 22 enters the mid-position hole 23, the rocker 2 is reset. When the rocker 2 rotates, the hand wheel 22 rotates synchronously with the sleeve 20, and always rubs against the left cover 6 of the base. When the rocker 2 returns to noon, the hand wheel 22 enters the noon hole. The operator can quickly sense whether the rocker 2 returns to the mid-position based on the hand feel feedback on the rocker 2.

[0028] In the second embodiment, there are no micro switches, and the signal is transmitted only through the Hall sensor 9 .

[0029] Compared with the prior art, the utility model has the following beneficial effects: friction positioning is achieved by clamping the rotating shaft with the friction block, and the angle of the rocker is kept stable, thereby outputting a stable signal and achieving precise control.
