[0013] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0014] Depend on Figures 1 to 4 It can be seen that a rotary friction positioning electric control handle includes a shell 1, a rotating shaft 2 is rotatably arranged in the shell 1, a rotary cover 3 is arranged at the upper end of the rotating shaft 2, a swivel 4 is arranged in the shell 1 and located at the lower end of the rotating shaft 2, a magnet 5 is arranged in the swivel 4, a PCB board 6 fixed in the shell 1 is arranged below the rotating shaft 2, a Hall sensor 7 corresponding to the magnet 5 is arranged on the PCB board 6, a rotating block 8 that rotates synchronously with the rotating shaft 2 is arranged in the shell 1, a locking block 10 is connected to the shell 1 via a spring 9, a groove 11 is arranged on the side of the rotating block 8, and the handle is in the initial position when the locking block 10 enters the groove 11, and friction positioning can be formed between the locking block 10 and the rotating block 8.
[0015] When the utility model is used in a specific way,
[0016] Connect the handle to the device. When the device needs to be operated, turn the rotary cover 3 to rotate the rotating block 8, disengage the locking block 10 from the groove 11, compress the spring 9, and generate pressure on the outer side of the rotating block 8. When it is rotated to a suitable angle, release the rotary cover 3. Under the thrust of the spring 9, pressure is generated between the locking block 10 and the rotating block 8. This pressure forms a friction positioning between the locking block 10 and the rotating block 8, which can keep the rotating shaft 2 in a stationary state, thereby ensuring the relative stability between the magnet 5 and the Hall sensor 7, and ensuring the stability of the output signal. There is no need to continuously control the handle to achieve accurate operation.
[0017] In the present handle, the locking block 10 is inserted into the groove 11 in the initial position. When the rotary cover 3 is turned, the initial position can be clearly felt. At this time, a greater force is required to turn the rotary cover 3. Conversely, when the handle is reset, the locking block 10 returns to the initial position when inserted into the groove 11, and the reset operation can be performed accurately. The feel of the rotary cover 3 can be used to quickly determine whether the handle is reset and in the initial position, and the operation is more convenient.
[0018] The housing 1 includes an upper mounting seat 12 and a lower mounting seat 13 . The PCB board 6 is arranged in the lower mounting seat 13 . The upper mounting seat 12 and the lower mounting seat 13 are detachably connected by screws for easy assembly.
[0019] A shaft sleeve 14 is provided on the upper mounting seat 12, and the rotating block 8 is rotatably arranged in the shaft sleeve 14, so as to facilitate positioning of the rotating block 8 and make it more convenient to rotate.
[0020] A limit plate 15 extends out from one side of the rotating block 8, and a limit block 16 is arranged in the shell 1. When the limit plate 15 contacts the limit block 16, the handle is in the initial position. The arrangement of the limit plate 15 and the limit block 16 enables the rotating shaft 2 to rotate only to one side, and is used as a unidirectional operating handle.
[0021] Compared with the prior art, the utility model has the following beneficial effects: a retractable locking block is arranged on the outer side of the rotating shaft, which can produce a friction positioning effect with the rotating block on the rotating shaft, thereby locking the angle of the rotating shaft, thereby eliminating the need to always hold the handle, and can also ensure continuous and stable output of the signal, and can reduce signal fluctuations caused by hand shaking during manual operation, thereby ensuring the accuracy of the operation.
