[0028] In the prior art, when measuring a conductor, a tape measure or a steel ruler is usually used for measurement. Due to the limitation of the measuring tool, after the measuring tool measures the limit length, it is necessary to mark it first, and then re-measure at the marked position, resulting in inaccurate measurement results. In addition, different arrangements of the conductors lead to inaccurate measurement results. The present invention can effectively solve the above problems.

[0029] Specifically, there are two situations for measuring the wire. The first is to measure the overall length of the wire. First, the wire on the first wire roller 101 is manually pulled out and passed through the guide wheel group 100, and then inserted into the wire entry hole of the wire drum 204. After the wire is inserted into the wire entry hole of the wire drum 204, it first contacts the measuring roller 209. The measuring roller 209 is laterally squeezed by the wire to drive the elastic slide bar 208 to shrink and slide. After sliding, the elastic slide bar 208 contacts and squeezes the trigger switch 303. The trigger switch 303 is squeezed to enable the drive motor 201 to work. At this time, the wire continues to slide along the top surface of the spiral plate 403 around the wire drum 204 until the wire is stuck between the two wire feeding wheels 406. Then the drive motor 201 is started, and the output shaft of the drive motor 201 drives the first The first rotating shaft 202 rotates, the first rotating shaft 202 drives the long plate 203 and the unlocking plate 502 to rotate, the long plate 203 drives the L-shaped frame 205 to rotate in the wire reel 204 around the center of the wire reel 204, the L-shaped frame 205 drives the sliding sleeve 207 to move, the sliding sleeve 207 slides along the spiral track 206 and drives the elastic sliding rod 208 and the measuring roller 209 to slide, and the measuring roller 209 contacts the surface of the wire when sliding, so that the elastic sliding rod 208 is always in a contracted state, as the sliding sleeve 207 slides along the spiral track 206, the sliding sleeve 207 is squeezed by the spiral track 206 to drive the elastic sliding rod 208 and the measuring roller 209 to slide downward, the first elastic member between the sliding sleeve 207 and the L-shaped frame 205 is contracted by force, and the unlocking plate 502 rotates and the unlocking plate 50 2 and the transmission rod 401 are stretched, and the first baffle plate 501 contacts the side wall of the transmission rod 401 to limit the transmission rod 401. The transmission rod 401 is restricted and cannot move. As the first rotating shaft 202 rotates, the counter 200 records the rotation distance of the first rotating shaft 202. After the measuring roller 209 and the unlocking plate 502 rotate one circle with the first rotating shaft 202 as the center, the wedge surface of the unlocking plate 502 contacts and squeezes the wedge surface of the first baffle plate 501, and the first baffle plate 501 slides upward under force to shrink the third elastic member. After the first baffle plate 501 slides, it no longer contacts the transmission rod 401. The transmission rod 401 is freed from the restriction and can move. At this time, the fourth elastic member between the transmission rod 401 and the unlocking plate 502 shrinks. The transmission rod 401 is retracted to slide along the annular track 402 of the first rotating shaft 202, and the transmission rod 401 drives the gear ring 404 to rotate horizontally, and the gear ring 404 rotates and drives the gear 405 to rotate, and the gear 405 drives the wire feeding wheel 406 on the lower side to rotate, and the wire feeding wheel 406 rotates and drives the wire to be drawn out to the wire outlet hole of the wire drum 204, and the wire slides along the spiral plate 403 so that the directions of the wires do not interfere with each other, which is more convenient for measuring the wires. At the same time, the sliding sleeve 207 drives the elastic sliding rod 208 to move to the connecting point at both ends of the spiral track 206, and the elastic sliding rod 208 drives the limiting plate 301 to be stuck in the vertical groove 302 of the wire drum 204. At this time, the limiting plate 301 is restricted by the vertical groove 302 to keep the elastic sliding rod 208 in a retracted state.The elastic slide bar 208 drives the measuring roller 209 to remain stable. At this time, the first elastic member between the slide sleeve 207 and the L-shaped frame 205 contracts and drives the slide sleeve 207 to slide upward and reset. The slide sleeve 207 drives the elastic slide bar 208 and the measuring roller 209 to slide and reset. After the measuring roller 209 is reset, it is always in contact with the wire, and the limit plate 301 is separated from the vertical groove 302. Therefore, when the slide sleeve 207 is reset, the trigger switch 303 is always in a squeezed state, so that the drive motor 201 can continue to work, and then repeat the above steps to measure the wire. When the end of the wire enters the wire reel 204 and the measuring roller 209 slides to the end of the wire and passes over, the measuring roller 209 does not Then the elastic slide bar 208 is in contact with the end of the wire to enable the elastic slide bar 208 to move. The elastic slide bar 208 is released to slide and drives the measuring roller 209 to slide with the limit plate 301. After the elastic slide bar 208 slides, it no longer contacts the trigger switch 303. After the trigger switch 303 is released from the squeeze, the drive motor 201 stops working. The output shaft of the drive motor 201 no longer drives the first rotating shaft 202 to rotate. After the first rotating shaft 202 stops rotating, the counter 200 stops recording. Then, the wire length is manually determined based on the data recorded by the counter 200, thereby completing the length measurement of the wire. The contact between the measuring roller 209 and the wire can accurately determine the position of the wire end, further improving the accuracy of the wire measurement result.

[0030] The second situation of measuring the wire is to cut the wire when it is measured to an appropriate length. First, the rotation distance of the first rotating shaft 202 is set manually through the panel on the counter 200, and then the above steps are repeated to measure the wire. When the first rotating shaft 202 rotates to the specified distance, the counter 200 controls the driving motor 201 to stop rotating, and then the wire is cut manually using a tool, thereby completing the measurement and cutting of the specified length of the wire.
