[0028] See also Figure 1-5 The utility model provides a technical solution: a cable length measuring device, including a bracket 1, a sleeve 2 is movably connected to the inner wall of the upper end of the bracket 1, a transmission rod 3 is movably provided on the inner wall of the sleeve 2, a sleeve 4 is fixedly connected to the end of the transmission rod 3, a scale rod 5 is fixedly installed on the outer wall of the sleeve 4 below the transmission rod 3, and a marking mechanism 6 is installed on the inner wall of the sleeve 4.

[0029] A positioning frame 7 is fixedly connected to the upper surface of the bracket 1 , a scale frame 8 is fixedly provided on the outer wall of the side of the positioning frame 7 , a movable frame 9 is sleeved on the outer wall of the scale frame 8 , and a knob 10 is provided on the inner wall of the movable frame 9 on the side of the scale frame 8 .

[0030] A pressing button 11 is respectively installed on the inner wall of the upper end of the positioning frame 7 and the movable frame 9, and a clamping plate 12 is movably installed on the lower end of the pressing button 11.

[0031] The bracket 1 and sleeve 2 in this example form a rotating structure, the sleeve 2 and the transmission rod 3 are threadedly connected, and the bracket 1 and the scale rod 5 are slidably arranged, so that the user can rotate the sleeve 2 to make the transmission rod 3 move in the sleeve 2, so that the transmission rod 3 pushes the sleeve 4 to move, and as the sleeve 4 moves, the sleeve 4 drives the scale rod 5 to slide relative to the bracket 1, so that the marking mechanism 6 can move stably, which is convenient for the marking mechanism 6 to mark different positions on the cable, and then facilitate the cable to be cut into different lengths.

[0032] The marking mechanism 6 in this example includes a pressure rod 601, a spring 602 and a marking pen 603. The pressure rod 601 is movably mounted on the inner wall of the sleeve 4, and the lower end of the pressure rod 601 is fixedly connected to the marking pen 603, which is convenient for marking the cable through the marking mechanism 6, thereby facilitating the cutting of the cable.

[0033] The pressure rod 601 and the sleeve 4 in this example are slidably connected, and the upper end surface of the sleeve 4 is connected to the upper outer wall of the pressure rod 601 through the spring 602, so that the user can press the pressure rod 601 to move downward relative to the sleeve 4, thereby driving the marking pen 603 to move downward, so that the marking pen 603 fits the cable to mark the cable, and at the same time, the pressure rod 601 is elastically supported by the spring 602, so that when the user releases the pressure rod 601, the pressure rod 601 returns to its original position and moves upward.

[0034] The scale frame 8 and the bracket 1 in this example are fixedly connected, and the scale frame 8 and the bracket 1 are both slidably connected to the movable frame 9. The movable frame 9 and the knob 10 are threadedly arranged, and the knob 10 and the scale frame 8 fit together, so that the user can pull the movable frame 9 to move, and the movable frame 9 moves along the scale frame 8 to straighten the cable. When the cable is straightened, the user rotates the knob 10 so that the knob 10 fits the scale frame 8, thereby limiting the movable frame 9, so that the cable is in a stable straightened state when being measured on the device.

[0035] The pressing button 11 in this example is threadedly connected to the positioning frame 7 and the movable frame 9 respectively, the pressing button 11 and the clamping plate 12 are rotatably arranged, and the clamping plate 12 forms a sliding structure with the positioning frame 7 and the movable frame 9 respectively, so that the user can rotate the pressing button 11 respectively to move the clamping plate 12 downward, thereby pressing the end of the cable to fit the positioning frame 7 or the movable frame 9, so that the device can stably limit the two ends of the cable.

[0036] Working principle: According to Figure 1-5As shown, the user inserts one end of the cable into the positioning frame 7 and aligns the end of the cable with the positioning frame 7, then the user rotates the push button 11 on the positioning frame 7, then the push button 11 moves down relative to the positioning frame 7, then the push button 11 pushes the clamping plate 12 to slide down relative to the positioning frame 7, then the clamping plate 12 squeezes the cable to stably fit the positioning frame 7, thereby completing the positioning of one end of the cable, similarly, the user inserts the other end of the cable into the movable frame 9 and moves the other end of the cable to align with the movable frame 9, then rotates the push button 11 on the movable frame 9 to position the other end of the cable, then when both ends of the cable are positioned, the user pulls the movable frame 9 to slide relative to the scale frame 8 and the bracket 1, at this time the device straightens the cable to be measured, next when the cable is straightened, the movable frame 9 is in a stationary state, then the user rotates the knob 10, then the knob 10 moves relative to the movable frame 9 to fit the scale frame 8, thereby limiting the scale frame 8, at this time the cable is in a stable straightened state on the device, then the user observes The position of the movable frame 9 relative to the scale frame 8 can obtain the length of the cable, so the device is convenient for straightening the cable for measurement, which ensures the measurement accuracy of the device and improves the practicality of the device. Then, when it is necessary to mark different positions on the surface of the cable, so as to facilitate the processing of the cable into different lengths, the user rotates the sleeve 2, and then the transmission rod 3 moves relative to the sleeve 2. Next, the transmission rod 3 drives the sleeve 4 to move, and as the sleeve 4 moves, the sleeve 4 drives the scale rod 5 to slide relative to the bracket 1. At this time, the sleeve 4 drives the marking mechanism 6 to move stably, and the distance moved by the marking mechanism 6 can be directly obtained by the position of the scale rod 5 relative to the bracket 1. Then, when the marking mechanism 6 moves to the desired position, the user presses the pressure rod 601 to move downward relative to the sleeve 4, and then the pressure rod 601 compresses the spring 602 to deform, and at the same time, the pressure rod 601 drives the marking pen 603 to move downward so that the marking pen 603 fits the cable, thereby marking the surface of the cable, which is convenient for the cable to be cut and processed.
