meanwhile, a fixing mechanism 10 for fixing the adjusting plate 9 is further arranged between the two support plates 7, the fixing mechanism 10 comprises guide grooves 1001 which are respectively formed in the top ends of the support plates 7 and are parallel to the corresponding sliding grooves I8, the bottom end of each adjusting plate 9 is connected with guide blocks 1002 which are located in the corresponding guide grooves 1001 and are clamped and slidably connected with the corresponding guide grooves 1001, each guide block 1002 is in threaded through connection with a lead screw 1003 located in the corresponding guide groove 1001, a connecting block 1004 is fixed at the central position inside each guide groove 1001, one ends, close to each other, of the two lead screws 1003 located on the same support plate 7 are connected with the corresponding connecting block 1004 through a bearing, and one ends, far away from each other, of the two lead screws 1003 located on the same support plate 7 are respectively provided with a handle located outside the corresponding support plate 7; in addition, two 11 with 8 vertically spouts in spout have all been seted up on the top of every regulating plate 9, and the top of every regulating plate 9 all has two splint 12 through two 11 symmetrical block sliding connection in the spout that correspond, and block sliding connection's concrete reason is as follows: a second sliding block 1201 is mounted at the bottom end of each clamping plate 12, each second sliding block 1201 is located in the corresponding second sliding groove 11 and is clamped and slidably connected with the corresponding second sliding groove 11, meanwhile, each second sliding groove 11 is a U-shaped groove, and each second sliding block 1201 is a U-shaped block matched with the corresponding U-shaped groove; in addition, an adjusting mechanism 13 for adjusting the distance between two corresponding clamping plates 12 is further arranged between the two support plates 7, the adjusting mechanism 13 includes a plurality of bolts 1301 respectively arranged on corresponding limiting frames, the two clamping plates 12 on each limiting frame are fixed by the corresponding bolts 1301, the two clamping plates 12 on the same adjusting plate 9 can be mutually matched to form a limiting frame, a sleeve 14 which is arranged on the corresponding support plate 7 and has the same inner diameter as the outer diameter of the rotating shaft 2 is clamped and fixed between the two limiting frames on the same side, the rotating shaft 2 is inserted between the two sleeves 14 and is fixed by the sleeve 14, so that the rotating shaft 2 can not rotate, in the embodiment, the position of the adjusting plate 9 which is slidably connected on the support plates 7 can be fixed by the action of the fixing mechanism 10, because the two adjusting plates 9 are symmetrically arranged on each support plate 7, the total number of the adjusting plates 9 is four, two support plates 7 are arranged on each bottom frame 1, so the distance between the two adjusting plates 9 can be adjusted according to the diameter of the rotating shaft 2, then the rotating shaft is fixed through the fixing mechanism 10, meanwhile, a limiting frame consisting of two clamping plates 12 is clamped and slidably connected on each adjusting plate 9, namely, four clamping plates 12 are arranged on each bottom frame 1, two limiting frames consist of four clamping plates 12 on each bottom frame 1, the rotating shaft 2 can be further fixed through the matching action of the two limiting frames and the adjusting plates 9, in addition, the distance between the two clamping plates 12 on the same limiting frame can be adjusted through the action of the adjusting mechanism 13, in this way, the distance between the two clamping plates 12 on the same limiting frame can be changed according to the model size of the sleeve 14 to fix the sleeve 14, because the inner diameter of the sleeve 14 is the same as the outer diameter of the rotating shaft 2, therefore, the fixing sleeve 14 is equivalent to fixing the rotating shaft 2, and as described above, by the cooperation of the fixing mechanism 10 and the adjusting mechanism 13, the present invention can be applied to rotating shafts 2 and sleeves 14 of different models and sizes and can fix the rotating shafts 2 and sleeves 14 of different models, after the rotating shafts 2 and the sleeves 14 are fixed, the rotation of the paying-off roller 3 around the rotating shaft 2 is smoother, otherwise, if the rotating shaft 2 rotates, the paying-off roller 3 also rotates, when the cable is actually pulled to drive the paying-off roller 3 to rotate, because the rotating shaft 2 also rotates, the rotating shaft 2 and the paying-off roller 3 may rotate synchronously, and when the rotating shaft 2 and the paying-off roller 3 rotate synchronously, the paying-off roller 3 winds the cable again, which is contrary to actively pulling out the cable, therefore, in order to avoid the problem, the best solution is to fix the rotating shaft 2, only the payout roller 3 is allowed to rotate.
