[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: A portable high-precision metering device, including a metering device 1. Fixed columns 101 are arranged in an array on the upper end face inside the metering device 1. A telescopic groove 102 is arranged inside the fixed column 101. A pressing component 2 is connected to the upper end inside the metering device 1. A plurality of telescopic rods 201 are fixedly connected to the lower end face inside the pressing component 2. A semi-circular limiting groove 203 is arranged in the middle of the lower end face of the pressing component 2. A rectangular groove 204 is arranged above the semi-circular limiting groove 203. A plurality of pressing rods 205 are rotatably connected inside the rectangular groove 204. Support rods 105 are fixedly connected to both sides of the middle of the lower end face inside the metering device 1. A metering roller 4 is rotatably connected to the upper end between the two support rods 105. An anti-slip coating 401 is arranged on the end face of the metering roller 4. A protective housing 5 is fixedly connected to the middle of one side end face of the metering device 1. An encoder 501 is fixedly arranged inside the protective housing 5. A cable 6 is arranged between the upper end of the metering roller 4 and the inside of the semi-circular limiting groove 203.

[0024] Furthermore, rectangular sliding grooves 103 are arranged on both side end faces inside the telescopic groove 102 of the fixed column 101, and a spring 104 is arranged inside the telescopic groove 102.

[0025] Furthermore, rectangular limiting parts 202 are fixedly connected to both upper ends of the telescopic rod 201.

[0026] Further, the upper end of the telescopic rod 201 is inserted into the inside of the telescopic groove 102, and the two rectangular limiting portions 202 are respectively slid into the inside of the two rectangular sliding grooves 103. A pull rod 3 is fixedly connected to the middle of the lower pressing assembly 2. The upper end of the pull rod 3 passes through the metering device 1 and extends out of the upper end face of the metering device 1 and is fixedly connected with a disc 301. The telescopic rod 201 is pushed downward by the spring 104, so that the telescopic rod 201 jointly pushes the lower pressing assembly 2 to descend, and the semi-circular limiting groove 203 presses the cable 6 downward, so that the lower end of the cable 6 is attached to the metering roller 4. When the cable 6 passes through the inside of the metering device 1, the metering roller 4 is driven to rotate. By pulling up the disc 301 to drive the pull rod 3 to move, the pull rod 3 drives the lower pressing assembly 2 to lift, so that the telescopic rod 201 is retracted into the telescopic groove 102 to compress the spring 104, and further the distance between the semi-circular limiting groove 203 and the upper end of the metering roller 4 is increased, facilitating the cable 6 to pass through.

[0027] Further, the lower pressing rod 205 is rotatably connected in the rectangular groove 204 through a rotating shaft 206. When the cable 6 moves inside the semi-circular limiting groove 203, the lower pressing rod 205 rotates to ensure the smooth movement of the cable 6.

[0028] Further, the metering roller 4 is rotatably connected between the two support rods 105 through a metering shaft 402. One end of the metering shaft 402 passes through the metering device 1 and extends into the protective housing 5 and is fixedly connected with an encoder 501. The cable 6 drives the metering roller 4 to rotate, so that the metering shaft 402 rotates. The encoder 501 records the number of rotations of the metering shaft 402, and the moving length of the cable 6 is calculated according to the cross-sectional circumference of the metering roller 4.

[0029] Further, a display 502 is fixedly connected to the upper end of the protective housing 5 on one side of the metering device 1. The display 502 is connected to the encoder 501 through a data cable. The moving length of the cable 6 recorded by the encoder 501 is directly displayed through the display 502, facilitating personnel to view.

[0030] Working principle: During use, the upper pulling disc 301 drives the pull rod 3 to move, and the pull rod 3 drives the lower pressing assembly 2 to lift, causing the telescopic rod 201 to retract into the telescopic groove 102 and compress the spring 104. As a result, the distance between the semi-circular limit groove 203 and the upper end of the length measuring roller 4 increases, facilitating the passage of the cable 6. After the cable 6 passes through the space between the semi-circular limit groove 203 and the upper end of the length measuring roller 4, release the disc 301, enabling the spring 104 to push the telescopic rod 201 to extend downward. Subsequently, the telescopic rods 201 together push the lower pressing assembly 2 to descend, causing the semi-circular limit groove 203 to press down on the cable 6, making the lower end of the cable 6 fit with the length measuring roller 4. When the cable 6 passes through the length measuring device 1, it drives the length measuring roller 4 to rotate. The length measuring roller 4 is rotatably connected between two support rods 105 through a length measuring shaft 402. One end of the length measuring shaft 402 passes through the length measuring device 1 and extends into the protective housing 5, where it is fixedly connected to the encoder 501. The cable 6 drives the length measuring roller 4 to rotate, thereby causing the length measuring shaft 402 to rotate. The encoder 501 records the number of rotations of the length measuring shaft 402, and based on the cross-sectional circumference of the length measuring roller 4, the moving length of the cable 6 is calculated. A display 502 is fixedly connected to the upper end of the protective housing 5 on one side of the length measuring device 1. The display 502 is connected to the encoder 501 through a data cable, and the moving length of the cable 6 recorded by the encoder 501 is directly displayed through the display 502, facilitating viewing by personnel. The entire device is small and portable.
