A connecting block 202 is fixedly connected between the upper side plate 3 and the bottom side plate 6 above and below the same end of each side connecting telescopic plate 201, and a mounting member 204 is fixedly connected between the upper side plate 3 and the bottom side plate 6 above and below the other end of each side connecting telescopic plate 201.

[0038] An upper through hole 2 is provided in the middle of the top support plate 1, and connecting pieces 15 are fixedly connected on both sides of the top support plate 1.

Bottom side plates 6 are fixedly connected to the lower ends of the box plates 5 on both sides. The bottom side plates 6 on both sides are fixedly connected to the bottom side plates 6, a bottom support plate 7 is rotatably installed between the bottom support plate 7, a lower through hole 16 is provided in the middle of the bottom support plate 7, support blocks 8 are fixedly connected to the lower surface of the bottom support plate 7 on both sides, a support base 10 is fixedly connected to the lower end of the support block 8, and side top blocks 9 are fixedly connected to the upper surface of the support base 10 on both sides, and the side top blocks 9 are located below the bottom side plate 6, and pull handles 13 are rotatably installed on both sides of the support block 8 and the side top block 9, and the pull handles 13 extend to the top of the upper side plate 3, and the pull handles 13 on both sides are fixedly connected to the upper side plate 3. A matching gear 18 is fixedly connected to the middle of the lower end of the pull handle 13, a deformable support assembly 12 is installed at the lower end of the pull handle 13, a fixed lifting assembly 11 is installed in the lower through hole 16, and an optical fiber fusion splicer 17 is installed on the fixed lifting assembly 11. The optical fiber fusion splicer 17 is located between the top support plate 1 and the bottom support plate 7. By pulling the handle 13, the entire optical fiber fusion splicer 17 and the box body can be moved to achieve a portable effect. When the optical fiber fusion splicer 17 needs to be used, pushing the pull handles 13 on both sides can drive the bearing plate 208 to rise and fall through the deformable support assembly 12, and can also drive the entire box body to deform into a trapezoid, so as to support the optical fiber fusion splicer 17 and ensure the stability of the optical fiber fusion splicer 17 during the working process. Subsequently, the optical fiber fusion splicer 17 can be lifted out of the box through the upper through hole 2 by the fixed lifting assembly 11, and the pull handle 13 can be fixed and locked, which is more convenient for the use of the optical fiber fusion splicer 17 and more portable, and accelerates the efficiency of optical fiber fusion splicing.

[0039] A screw rod 104 is fixedly connected to the upper surface of the worm gear 101, and the screw rod 104 on both sides is connected to the matching rod 105 through the surface thread meshing, and the upper end of the matching rod 105 is fixedly connected to a No. 1 mounting plate 106, and the upper surface of the No. 1 mounting plate 106 is fixedly connected to the optical fiber fusion splicer 17, and the front and rear sides of the inner wall of the lower through hole 16 are fixedly connected to mounting sheet metal 107, and a rotating shaft 108 is rotatably installed between the other ends of the mounting sheet metal 107 on both sides, and a rocker 110 is fixedly connected to one side of the rotating shaft 108, and a limited top block 114 is provided at the lower end of the rocker 110, and the limited top block 114 and the matching gear 18 are arranged in coordination, and a mounting groove 109 is provided in the middle part of the upper end of each rocker 110, and a No. 1 and No. 2 mounting blocks 111 are rotatably installed in the mounting groove 109, and a spring top rod 112 is fixedly connected to one side of the No. 1 and No. 2 mounting blocks 111, and the other end of the spring top rod 112 is fixedly connected to a fixed block 113, The fixing block 113 is fixedly connected to the upper surface of the bottom support plate 7. When the carrying plate 208 is lifted to a certain height, the starting motor 103 drives the worm 102 to rotate. Since the worm 102 is connected to the worm wheel 101 through threaded engagement, the worm wheel 101 can be driven to rotate. When the worm wheel 101 rotates, the screw rod 104 can be driven to rotate. Since the screw rod 104 is connected to the matching rod 105 through the threaded engagement on the surface, and the matching rod 105 is fixedly connected to the lower surface of the No. 1 mounting plate 106, the No. 1 mounting plate 106 can be driven to rise and fall, so that the optical fiber fusion splicer 17 on the No. 1 mounting plate 106 is pushed out through the upper through hole 2 for optical fiber processing. When the carrying plate 208 rises, the seesaw 110 cannot be squeezed, and the spring top rod 112 will play a role of contraction to drive the seesaw 110 to rotate around the rotating shaft 108, so that the limit top block 114 at the lower end of the seesaw 110 contacts with the matching gear 18 to achieve the effect of pulling the handle 13 to lock.

[0040] The second mounting plate 206 is fixedly connected to the front and rear sides of the upper surface of the bottom support plate 7, and a lifting plate 205 is movably installed on each of the second mounting plates 206. The upper end of the lifting plate 205 is fixedly connected to the top support plate 1, and the four corners between the top support plate 1 and the inner surface of the bottom support plate 7 are fixedly connected with telescopic rods 207. A bearing plate 208 is movably installed on each of the telescopic rods 207. A mounting through hole 210 is provided in the middle of the bearing plate 208, and a fixing plate 209 is fixedly connected to the lower surface of the mounting through hole 210. Transmission rods are fixedly provided at both ends below the pulling handle 13. 211, a sliding seat 214 is rotatably mounted on the upper end of each transmission rod 211, a slide rail 215 is mounted on the upper end of each slide rail 214, and the slide rail 215 is fixedly connected to the lower surface of the upper side plate 3, and a slide groove 212 is arranged in the middle of each transmission rod 211. The two transmission rods 211 at the same end are staggered, and an extension shaft 216 is arranged in the two staggered transmission rods 211. One end of the extension shaft 216 is fixedly connected to the limited block 213, and the other end of the extension shaft 216 extends to the upper sides of the bearing plate 208, and the other end of the extension shaft 216 on both sides is fixedly connected to a mounting plate 208. Block 217, the No. 1 mounting block 217 is fixedly connected to both sides of the upper surface of the bearing plate 208. When the handle 13 is pushed and rotated to both sides, the transmission rods 211 on both sides can be driven to rotate with the handle 13. When the transmission rods 211 on both sides are rotated to both sides, the top support plate 1 can be pushed to move upward. Since the upper side plates 3 are installed on both sides of the top support plate 1 through the connecting pieces 15, and the upper side plates 3 and the bottom support plate 7 below are connected together through the connecting corner pieces 4 and the box plate 5, the box body can be transformed from a square to a trapezoid, and the side connecting telescopic plate 201 can be used to adjust the side of the box body. The gap is filled. When the No. 2 mounting plate 206 and the lifting plate 205 are installed between the top support plate 1 and the bottom support plate 7, the lifting and lowering of the top support plate 1 can be limited and supported. At the same time, the gap overlapped by the slide groove 212 of the transmission rod 211 is larger, and since an extension shaft 216 is installed in the slide groove 212, the extension shaft 216 can be pushed to move up and down, and the inner side of the extension shaft 216 is connected to the supporting plate 208 through the No. 1 mounting block 217, it can be driven to move up and down. Since the supporting plate 208 is installed on the telescopic rod 207, the lifting and lowering of the supporting plate 208 can be limited.

[0041] The working principle of this embodiment is:

[0042] First, when the push-pull handle 13 is rotated to both sides, the transmission rods 211 on both sides can be driven to rotate with the pull handle 13. When the transmission rods 211 on both sides are rotated to both sides, the top support plate 1 can be pushed to move upward. Since the upper side plates 3 are installed on both sides of the top support plate 1 through the connecting pieces 15, and the upper side plates 3 and the bottom support plate 7 below are connected together through the connecting corner pieces 4 and the box plate 5, the box body can be transformed from a square to a trapezoid. The side connecting telescopic plate 201 can be used to supplement the gap on the side of the box body. When the No. 2 mounting plate 206 and the lifting plate 205 are installed between the top support plate 1 and the bottom support plate 7, the lifting and lowering of the top support plate 1 can be limited and supported. At the same time, the gap overlapped by the sliding groove 212 of the transmission rod 211 is larger, and since an extension shaft 216 is installed in the sliding groove 212, the extension shaft 216 can be pushed to move up and down, and the inner side of the extension shaft 216 is connected to the bearing plate 208 through the No. 1 mounting block 217, which can drive it up and down. Lifting and moving, since the carrying plate 208 is installed on the telescopic rod 207, the lifting and lowering of the carrying plate 208 can be limited. When the carrying plate 208 is lifted to a certain height, the motor 103 is started to drive the worm 102 to rotate. Since the worm 102 is connected to the worm wheel 101 through threaded engagement, the worm wheel 101 can be driven to rotate. When the worm wheel 101 rotates, the lead screw 104 can be driven to rotate. Since the lead screw 104 is connected to the matching rod 105 through the threaded engagement on the surface, and the matching rod 105 is fixedly connected Connected to the lower surface of the No. 1 mounting plate 106, it can drive the No. 1 mounting plate 106 to rise and fall, so that the optical fiber fusion splicer 17 on the No. 1 mounting plate 106 can be pushed out through the upper through hole 2 to perform optical fiber processing. When the supporting plate 208 rises, it cannot squeeze the seesaw 110, and the spring top rod 112 will shrink and drive the seesaw 110 to rotate around the rotating shaft 108, so that the limiting top block 114 at the lower end of the seesaw 110 contacts the matching gear 18 to achieve the effect of pulling the handle 13 to lock.
