Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: Please refer to Figure 1 , Figure 2 The optical cable cutting device shown in the figure includes a base 1, a bracket 2 is fixedly installed at the center of the upper end of the base 1, guide rollers for conducting the cable are installed at both ends of the upper side of the base 1, and also includes a cutting mechanism 3 installed on the lower side of the bracket 2, the cutting mechanism 3 is used to cut the cable; a pressing structure 4 is used to press the cable, and two symmetrically distributed pressing structures 4 are installed on the left and right sides of the bracket 2; a grinding structure 5 is used to grind the cutting mechanism 3, and two symmetrically distributed grinding structures 5 are installed inside the base 1 and are located directly below the cutting mechanism 3; an adjusting structure 6 is used to adjust the distance between the two grinding structures 5, and the adjusting structure 6 is also installed inside the base 1.

[0029] See also Figure 5 , Figure 6 The pressing structure 4 includes two hydraulic rods 301 fixedly installed on the lower side of the bracket 2, and the lower end of the hydraulic rod 301 is fixedly connected to a connecting plate 302. The hydraulic rod 301 can drive the connecting plate 302 to move up and down. A cutter 303 is fixedly installed at the center of the lower end of the connecting plate 302. The pressing structure 4 includes two semi-enclosed sleeves 401 fixedly embedded on the connecting plate 302, and a gasket 402 is movably embedded at the lower end of the semi-enclosed sleeve 401. The cross-sectional shape of the gasket 402 is circular, and the gasket 402 can move up and down inside the semi-enclosed sleeve 401.

[0030] See also Figure 6 A spring 403 is installed inside the semi-enclosed sleeve 401, and the two ends of the spring 403 are movably abutted against the semi-enclosed sleeve 401 and the gasket 402 respectively. A connecting rod 404 is fixedly embedded at the center of the lower end of the gasket 402. The gasket 402 can prevent the connecting rod 404 from detaching from the semi-enclosed sleeve 401. The lower end of the connecting rod 404 is fixedly connected to a pressing plate 405, and the lower end of the pressing plate 405 is fixedly embedded with an anti-skid pad 406. The upper end of the base 1 is located directly below the anti-skid pad 406 and is fixedly embedded with an anti-skid pad 407. The anti-skid pad 406 and the anti-skid pad 407 can increase the friction between the cable and the pressing plate 405 and the base 1.

[0031] Working principle: The hydraulic rod 301 drives the connecting plate 302 and the cutter 303 to move downward. Before the cutter 303 contacts the cable, the pressure plate 405 will first squeeze the cable through the anti-slip pad 406, and as the cutter 303 continues to move downward, the connecting rod 404 will shrink toward the inside of the semi-enclosed sleeve 401. Under the compression force of the spring 403, the pressure of the pressure plate 405 on the cable will gradually increase, so that in the process of the cutter 303 cutting the cable, the cable located on the lower side of the cutter 303 is always in a straight state, which is conducive to the cutter 303 to quickly cut the cable, and effectively improves the cutting efficiency of the cable.

[0032] Example 2: Please refer to Figure 3 This embodiment further explains the first embodiment. The grinding structure 5 includes a grinding stone 501 that can move left and right inside the base 1. The upper edge of the grinding stone 501 is chamfered with an arc, which facilitates the insertion of the cutter 303 between the two grinding stones 501. A fixed plate 502 is fixedly sleeved on the outer side of the grinding stone 501, and the fixed plate 502 is located on the side of the two grinding stones 501 away from each other.

[0033] See also Figure 3 , slopes are provided at both ends of the fixed plate 502, and the slopes are located on the side where the two fixed plates 502 are close to each other, and a plurality of pins 503 distributed at equal distances are fixedly embedded on the side of the fixed plate 502 away from the grinding stone 501, and a spring 2 504 is movably sleeved on the outer side of the pin 503, and the two ends of the spring 2 504 are movably abutted against the base 1 and the fixed plate 502 respectively, and the pin 503 can prevent the spring 2 504 from bending during the compression process, and the connection between the cutter 303 and the grinding stone 501 is sliding contact.

[0034] In this embodiment, when the cutter 303 becomes blunt during use, the personnel controls the two grinding stones 501 to resist each other. During the downward movement of the cutter 303, the cutter 303 will be inserted between the two grinding stones 501 through the two arc chamfers of the grinding stones 501. The two grinding stones 501 will fit tightly with the two sides of the cutter 303 under the drive of the compression elastic force of the spring 2 504, so that the cutter 303 can automatically contact and rub with the two grinding stones 501 during the upward and downward movement, thereby realizing automatic grinding of the cutter 303 without disassembling the cutter 303.

[0035] Example 3: Please refer to Figure 3 , Figure 4 This embodiment further explains Example 2. The adjustment structure 6 includes a bidirectional screw 601 rotatably connected to the base 1 through a bearing. The bearing can reduce the friction between the bidirectional screw 601 and the base 1. The outer thread of the bidirectional screw 601 is sleeved with two symmetrically distributed sliders 602, and the connection between the slider 602 and the base 1 is a sliding contact.

[0036] See also Figure 4 A connecting rod 603 is fixedly embedded at the center of the upper end of the slider 602, and a push block 604 is fixedly connected to the upper end of the connecting rod 603. The push block 604 can move back and forth inside the base 1, and the cross-sectional shape of the push block 604 is a right-angled trapezoid. The push block 604 is in sliding contact with the fixed plate 502 through a slope.

[0037] In this embodiment: after the cutting knife 303 is polished, the personnel rotates the bidirectional screw 601, and the bidirectional screw 601 rotates to drive the two sliding blocks 602 and the push block 604 to move closer to each other. During the movement, the push block 604 is inserted between the two fixed plates 502 through the slope of the fixed plate 502, and during the continued movement, the two fixed plates 502 and the two grinding stones 501 are driven away from each other, so that the cutting knife 303 will not contact the grinding stone 501 during the up and down movement, which can avoid the cutting knife 303 from contacting and rubbing with the grinding stone 501 for a long time, causing serious wear of the cutting knife 303.
