[0022] Embodiment 2, refer to the attached Figure 1-16 On the basis of the first embodiment, in order to achieve the docking of the fixed connection seat 23 and the sliding connection seat 24, the present embodiment proposes that: the inner surface of the center groove 230 is slidably connected with a movable plate 231, one end of the movable plate 231 is fixedly connected with a connection frame 232, and the other end of the connection frame 232 is fixedly connected with a trapezoidal end block 2321, the trapezoidal end block 2321 and the center line of the connection frame 232 are coaxially distributed, and the outer surface of the trapezoidal end block 2321 is set as a rounded corner; the outer surfaces of both sides of the connection frame 232 are respectively fixedly connected with fixed tooth rods 233, one side of the connection frame 232 is fixedly connected with two sets of parallel fixed tooth rods 233, and the fixed tooth rods 233 are fixedly connected to the inner surface of the center groove 230. The outer side surface of rod 1 233 is meshed and rotated with a parallel gear 234, and the outer surface of the parallel gear 234 is correspondingly transmitted with the outer surface of the fixed gear rod 1 233; the central inner surface of the parallel gear 234 is fixedly connected to the shaft rod 2341, and the central outer surface of the shaft rod 2341 is fixedly connected to the rotating knob 235, and the rotating knob 235 is arranged on the inner side of the arc-shaped side groove 2300; the outer surface of the sliding connection seat 24 close to the fixed connection seat 23 is fixedly connected to the fixed gear rod 241, and the outer surface of the fixed gear rod 241 is adapted to mesh with the outer surface of the parallel gear 234, and the fixed gear rod 241 is symmetrically distributed about the center line of the sliding connection seat 24 In this embodiment, the fixed connection seat 23 is fixed to the inner side of the fixed slide rail 1 21, and the sliding connection seat 24 is slidably installed on the inner side of the fixed slide rail 22. After the optical fiber group 15 is pulled to a suitable position, one end of the optical fiber group 15 is covered and fixed by the optical fiber flange seat 25. At this time, the sliding connection seat 24 is pushed toward one side of the fixed connection seat 23, so that the optical fiber group 15 and the laser chip 13 are gradually brought closer to each other, which is convenient for subsequent coupling connection; specifically, when the sliding connection seat 24 is pushed toward one end of the fixed connection seat 23, the fixed gear rod 241 is continuously inserted into the side of the center groove 1 230. When the fixed gear rod 241 contacts the surface of the parallel gear 234, the parallel gear 234 rotates under the effect of adaptive meshing transmission, and the shaft rod 2341 and the rotating knob 235 rotate synchronously at this time, as shown in FIG. Fig.11As shown, at this time, the sliding connection seat 24 and the fixed connection seat 23 are in a separated state. When the second fixed tooth bar 241 continues to advance, the second fixed tooth bar 241 drives the parallel gear 234 to rotate. Subsequently, the rotating parallel gear 234 drives the inner first fixed tooth bar 233 to move. The first fixed tooth bar 233 drives the movable plate 231 and the trapezoidal end block 2321 to advance towards one end of the sliding connection seat 24. When the advancing end of the second fixed tooth bar 241 is completely in contact with the side wall of the first central groove 230, at this time, the fixed connection seat 23 and the sliding connection seat 24 are completely docked; and as Figure 12-13 shown, at this time, the sliding connection seat 24 and the fixed connection seat 23 are in a completely docked state. Then, the installation position of the optical fiber group 15 is judged through the docking position of the fixed connection seat 23 and the sliding connection seat 24, and the operation is convenient.

[0023] Embodiment 3. Referring to the attached Figure 1-16 , on the basis of Embodiment 2, in order to further lock the fixed connection seat 23 and the sliding connection seat 24 after complete docking, the present embodiment also proposes that: a C-shaped plate 242 is fixedly installed at one end of the second central groove 240. An elastic clamping assembly is arranged inside the C-shaped plate 242. The elastic clamping assembly includes a central block 243 and a hinged push plate 244. The hinged push plate 244 is movably installed inside the C-shaped plate 242. The central block 243 is fixedly installed at the center of the C-shaped plate 242. One end of the hinged push plate 244 is rotatably connected to the outer surface of the central block 243; an arc-shaped elastic wire 245 is fixedly connected to the outer surface of the hinged push plate 244, and the other end of the arc-shaped elastic wire 245 is fixedly connected to the inner surface of the C-shaped plate 242. There are two groups of hinged push plates 244 and they are symmetrically distributed about the center of the central block 243. An elastic tension sheet 246 is fixedly connected to the inner surface of the two groups of hinged push plates 244, and the surface of the hinged push plate 244 is in movable abutment with the outer surface of the trapezoidal end block 2321; In the present embodiment, when the ends of the fixed connection seat 23 and the sliding connection seat 24 are in contact with each other, at this time, the trapezoidal end block 2321 enters the inside of the C-shaped plate 242 and pushes the two groups of hinged push plates 244 distributed on both sides. At this time, the hinged push plates 244 are relatively opened. The elastic tension sheet 246 between the two groups of hinged push plates 244 is tensioned, and at this time, the arc-shaped elastic wire 245 is elastically compressed by the push of the hinged push plate 244. Thus, both the elastic tension sheet 246 and the arc-shaped elastic wire 245 generate a reverse elastic force to clamp the trapezoidal end block 2321 inside the hinged push plate 244; it should be noted that a jack is opened on the inner surface of one end of the first fixed tooth bar 233 close to the C-shaped plate 242. When the hinged push plate 244 is pushed by the trapezoidal end block 2321 and opens to both sides, the end of the hinged push plate 244 is inserted into the jack when it reaches a certain position. Then, the first fixed tooth bar 233 will not retract randomly without external force; It should be noted that when the fixed connection seat 23 and the sliding connection seat 24 need to be detached, the operator only needs to place his hand on the rotating knob 235 inside the arc-shaped side groove 2300, as shown in FIG. Fig.13 As shown, the rotating knobs 235 on both sides are pushed inward respectively to realize the rotation of the rotating knobs 235. At this time, the fixed gear rod 241 gradually moves upward, and the fixed gear rod 1 233 also retreats to the inside of the center groove 1 230. In this way, the trapezoidal end block 2321 releases the pushing engagement with the hinged push plate 244. When the sliding connection seat 24 is pushed a certain distance, the fixed gear rod 241 is disengaged from the parallel gear 234, and then the operator only needs to manually pull out the sliding connection seat 24 and the optical fiber group 15 as a whole.

[0024] Embodiment 4, refer to the attached Figure 1-16 On the basis of the third embodiment, in order to make the movable plate 231, the connecting frame 232 and the fixed gear rod 233 retreat and be stored in a limited position, the present embodiment further proposes that: the lower surface of the movable plate 231 is slidably connected to the inner wall of the central groove 230, the end of the movable plate 231 away from the connecting frame 232 is fixedly connected with a triangular cone block 2311, the triangular cone block 2311 is a right-angled triangle structure, the upper surface of the movable plate 231 is provided with a settling groove 2310, and the inner surface of the settling groove 2310 is movably connected with a gravity self-locking component; The gravity self-locking assembly includes a fixed ear plate 26 and a locking rod 262. The cross section of the locking rod 262 is a "T"-shaped structure. The fixed ear plate 26 is fixedly installed on the upper surface of the chip mounting seat 201. The upper surface of the fixed ear plate 26 is fixedly connected with an elastic sheet 261. The upper end of the elastic sheet 261 is fixedly connected to the inner side surface of the upper end of the locking rod 262. The outer surface of the locking rod 262 is slidably installed on the inner wall of the chip mounting seat 201. The outer surface of the lower end of the locking rod 262 is movably plugged into the inner surface of the landing groove 2310. In this embodiment, when the fixed gear rod 241 is pushed and moved away from the fixed connection seat 23, the connection frame 232 and the movable plate 231 as a whole drive the trapezoidal end block 2321 and the shaped plate 242 to evacuate. Then, the fixed gear rod 1 233 retreats to one end of the fixed ear plate 26 under the rotation of the parallel gear 234. Figure 14-16As shown, the movable plate 231 drives the triangular cone block 2311 to move. When the triangular cone block 2311 retreats, its inclined surface contacts the bottom end of the locking rod 262, and the locking rod 262 is gradually lifted up by the triangular cone block 2311. At this time, the elastic sheet 261 is also stretched. When the bottom end of the locking rod 262 reaches the landing groove 2310, the locking rod 262 is elastically stored by the elastic sheet 261 to restore the initial position and lock the movable plate 231. In this way, when the inner element of the fixed connection seat 23 is not in use, it can also be automatically stored with the chip mounting seat 201, and ensure that it is transported. This design can ensure that when the sliding connection seat 24 is evacuated from the fixed connection seat 23, the internal components of the fixed connection seat 23 are self-locked simultaneously; and it should be noted that if the movable plate 231 needs to be released from the restriction, the operator only needs to manually pull up the locking rod 262 to make the bottom end of the locking rod 262 disengage from the landing groove 2310, and then rotate the knob 235 to push out the movable plate 231 again for use, thereby avoiding wear between the components of the pump laser and extending the overall service life of the 980nm pump laser.

[0025] Embodiment 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, the present invention further provides a method for using a 980nm pump laser, comprising the following steps: Step 1, first insert the optical fiber group 15 into the corresponding position of the laser through the flexible connection part sleeve hose 14, and pass one end of the optical fiber group 15 through the interior of the pump laser body 1, pull the optical fiber group 15 to a suitable position, and then cover and fix one end of the optical fiber group 15 through the optical fiber flange seat 25, and at this time, push the sliding connection seat 24 toward one side of the fixed connection seat 23, so that the optical fiber group 15 and the laser chip 13 are gradually brought close to each other, which is convenient for subsequent coupling connection; Step 2, when the sliding connection seat 24 is pushed toward one end of the fixed connection seat 23, the fixed gear rod 241 is continuously inserted into the side of the center groove 1 230, and when the fixed gear rod 241 contacts the surface of the parallel gear 234, the parallel gear 234 rotates under the effect of adaptive meshing transmission, and the shaft rod 2341 and the rotating knob 235 rotate synchronously, such as Fig.11As shown, at this time, the sliding connection seat 24 and the fixed connection seat 23 are in a separated state. When the second fixed rack 241 continues to advance, the second fixed rack 241 drives the parallel gear 234 to rotate. Subsequently, the rotating parallel gear 234 drives the inner first fixed rack 233 to move. The first fixed rack 233 drives the movable plate 231 and the trapezoidal end block 2321 to advance towards one end of the sliding connection seat 24. When the advancing end of the second fixed rack 241 is completely in contact with the side wall of the first central groove 230, the fixed connection seat 23 and the sliding connection seat 24 are completely docked; Step 3: When the ends of the fixed connection seat 23 and the sliding connection seat 24 are in contact with each other, at this time, the trapezoidal end block 2321 enters the inner side of the C-shaped plate 242 and pushes the hinge push plates 244 distributed on both sides. At this time, the hinge push plates 244 are relatively opened, and the elastic tensioning sheet 246 between the two hinge push plates 244 is tensioned. And at this time, the arc-shaped elastic wire 245 is elastically compressed by the pushing of the hinge push plate 244. In this way, both the elastic tensioning sheet 246 and the arc-shaped elastic wire 245 generate a reverse elastic force to clamp the trapezoidal end block 2321 inside the hinge push plate 244; Step 4: When the second fixed rack 241 is pushed and moves away from the fixed connection seat 23, at this time, the connection frame 232 and the movable plate 231 as a whole drive the trapezoidal end block 2321 to evacuate from between the C-shaped plate 242. Then, under the rotation of the parallel gear 234, the first fixed rack 233 retreats towards one end of the fixed ear plate 26. The movable plate 231 drives the triangular cone block 2311 to move. When the triangular cone block 2311 retreats, the inclined surface part thereof contacts the bottom end position of the locking rod 262, and the locking rod 262 is gradually lifted by the triangular cone block 2311. At this time, the elastic sheet 261 is also stretched. When the bottom end position of the locking rod 262 reaches the settling groove 2310, the locking rod 262 returns to its initial position under the elastic energy storage of the elastic sheet 261 and locks the movable plate 231. In this way, when the components inside the fixed connection seat 23 are not in use, automatic storage with the chip mounting seat 201 can also be achieved, and it is ensured that no random movement and collision will occur during transportation. This design can ensure that while the sliding connection seat 24 evacuates from the fixed connection seat 23, the internal devices of the fixed connection seat 23 are self-locked synchronously; Step 5: To release the restriction on the movable plate 231, the operator only needs to manually lift the locking rod 262 upward to make the bottom end of the locking rod 262脱离 the settling groove 2310, and then rotate the rotary knob 235 to push out the movable plate 231 for use again, avoiding wear between the components of the pump laser and extending the overall service life of the 980nm pump laser.
