[0019] The present application provides a wiring measurement tool, which is mainly used to solve the problem that before wiring, a certain length of cable needs to be measured and then the cable is cut to obtain a fixed length of cable. The current measurement method is generally to measure with a tape measure, which requires the user to straighten the cable before measuring. When the cable is long, it is not only troublesome, but also the measurement accuracy is relatively low. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0020] A wiring measurement tool comprises: a mounting frame 1 with two rollers 2 arranged on the top, after the user places the cable between the two rollers 2, the two rollers 2 are respectively attached to the two sides of the cable by the second driving mechanism 4, and the two rollers 2 are controlled to rotate by the first driving mechanism 3, so as to drive the cable to move, and at the same time, a symmetrically arranged infrared transmitter 5 and an infrared receiver 6 are arranged on one side of the mounting frame 1, and the user can limit the position of the infrared transmitter 5 and the infrared receiver 6 to one side of the mounting frame 1 by the limiting mechanism 7, and a PLC control is fixedly installed on the surface of the mounting frame 1 The PLC controller 8 is electrically connected to the infrared transmitter 5, the infrared receiver 6, and the first driving mechanism 3. In this way, during the movement of the cable, the PLC controller 8 can obtain the rotation speed of the two rollers 2 and the movement time of the cable, thereby obtaining the length of the cable passing through. The main components of the first driving mechanism 3 are: two mounting blocks 301, and the two rollers 2 are respectively rotated and plugged into the surfaces of the two mounting blocks 301, and the inner walls of the two mounting blocks 301 are fixedly installed with motors 302, and the output ends of the two motors 302 are respectively fixedly installed on the two rollers 2, the PLC controller 8 is electrically connected to the two motors 302, and the user controls the output ends of the two motors 302 to rotate through the PLC controller 8, so as to drive the two rollers 2 to rotate. The main components of the second driving mechanism 4 are: a double-headed cylinder 402 fixedly mounted on the inner wall of the mounting frame 1, and two mounting blocks 301 are respectively fixedly mounted on the two ends of the double-headed cylinder 402. At the same time, two driving grooves 401 are provided on the surface of the mounting frame 1, and the two rollers 2 are respectively slidably plugged into the surfaces of the two driving grooves 401. In this way, the user controls the output ends of the two motors 302 through the PLC controller 8 to rotate, so as to drive the two rollers 2 to rotate. The double-headed cylinder 402 can be extended and retracted to drive the two rollers 2 to move closer to or away from each other, wherein the main components of the limiting mechanism 7 are: a limiting frame 701, an infrared transmitter 5 and an infrared receiver 6 are respectively fixedly installed on both sides of the inner wall of the limiting frame 701, a T-shaped block 702 is slidably inserted at the bottom of the mounting frame 1, and the T-shaped block 702 is fixedly installed on the surface of the limiting frame 701, and finally, the user rotates the baffle 704 installed at the bottom of the mounting frame 1 through the damping shaft 703, and sets the baffle 704 on the surface of the T-shaped block 702, so as to achieve the limitation of the limiting frame 701.

[0021] When in use, the user places one end of the cable to be measured between the two rollers 2, and then controls the positions of the two rollers 2 through the second drive mechanism 4 in turn, so that the two rollers 2 fit the surface of the cable, and controls the rotation of the two rollers 2 through the first drive mechanism 3, so as to drive the cable to move. After the cable moves between the infrared transmitter 5 and the infrared receiver 6, the PLC controller 8 can obtain the rotation speed of the roller 2 through the first drive mechanism 3. Because the circumference of the place where the roller 2 contacts the cable after one rotation is unchanged, and the PLC controller 8 can obtain the cable movement time through the infrared transmitter 5 and the infrared receiver 6, the PLC controller 8 can obtain the length of the passed cable through the above data, and then cut the cable into sections to obtain a cable of relatively long and accurate length, which fully reflects the practicality of the device.
