[0009] According to the thin rotary switch encoder, the slide frame is slidably connected to the guide plate.

[0010] According to the thin rotary switch encoder, a pull handle is fixedly connected to the outer side of the pull plate, so as to facilitate the pull plate to move.

[0011] According to the thin rotary switch encoder, the handle is arranged in a U-shaped structure.

[0012] Beneficial effects:

[0013] By providing a guide plate, a sliding frame, a fixed frame, a movable rod, a card block, a card slot, a control knob, a pull plate and a pull handle, it is convenient to limit the control knob by pulling the pull handle and moving the pull handle, so as to avoid accidentally touching the control knob when not in use.

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 A thin rotary switch encoder comprises a main body 1: a control knob 2 and a limit unit 4 are arranged on the upper side of the main body 1, a scale ring 3 is fixedly connected to the upper side of the main body 1, and the scale ring 3 is convenient for intuitively controlling the electrical signal.

[0024] The limiting unit 4 includes a guide plate 401, which is fixedly connected to the upper sides of the left and right ends of the main body 1. A sliding frame 402 is arranged on the outer sides of the left and right guide plates 401. The upper side of the sliding frame 402 is fixedly connected to the fixed frame 403. The upper side of the fixed frame 403 is provided with a moving rod 404. The lower end of the moving rod 404 passes through the lower side of the fixed frame 403 and is fixedly connected to a card block 407. A card slot 406 is provided on the upper side of the control knob 2. The upper end of the moving rod 404 is fixedly connected to a pull plate 405. A spring 408 is fixedly connected between the pull plate 405 and the fixed frame 403. The moving rod 404 is slidably connected to the fixed frame 403. The card slot 406 and the card block 407 are adapted to be arranged. The sliding frame 402 is slidably connected to the guide plate 401 , a pull handle 409 is fixedly connected to the outer side of the pull plate 405, and the pull handle 409 is a U-shaped structure. When in use, first pull the pull handle 409, the pull handle 409 drives the pull plate 405 to move, the pull plate 405 drives the moving rod 404 to move, and the moving rod 404 drives the card block 407 to move, and then move the pull handle 409 forward, the pull handle 409 drives the fixed frame 403 to slide, and the control card block 407 corresponds to the card slot 406. At this time, the spring 408 is straightened, and under the action of the elastic force of the spring 408, it is easy to control the pull plate 405 to descend, and the pull plate 405 drives the card block 407 on the moving rod 404 to move, so that the card block 407 moves to the card slot 406, so that the control knob 2 is limited, to avoid accidental touching when the control knob 2 is not in use.

[0025] Working principle: When in use, first pull the handle 409 to pull the block 407 up, then move the handle 409 so that the handle 409 drives the block 407 on the fixed frame 403 to move back and forth, and release your hand. Under the action of the elastic force of the spring 408, the block 407 is connected to the slot 406, which is convenient for limiting the control knob 2 and avoiding accidental touching of the control knob 2 when the thin rotary switch encoder is not used.
