[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During operation, the cable reel fixing support device has an effective support fixing and rotation adjustment structure and a mobile adjustment structure by providing a stable base, a slide rod, a support pulley, a fixed vertical plate, a conical plug A, a retractable adjustment shaft, a conical plug B, a telescopic support adjustment mechanism, a roller, a synchronous telescopic adjustment mechanism and an adjustment transmission component. The support fixing and rotation adjustment structure can effectively ensure the stability of the cable reel and can effectively perform the reeling and unreeling operations on the cable reel, while the mobile adjustment structure can facilitate the mobile operation of the cable reel, thereby effectively improving the convenience and stability of the cable reel. In addition, the cable reel fixing support device has a simple structural design, is convenient and easy to use and adjust, and is stable and reliable. Its performance can meet the use requirements of the cable reel.

[0015] (2) Install the cable drum body between the surfaces of the two supporting pulleys so that the center hole of the cable drum body is aligned with the conical plug block A and the conical plug block B. Then, use an electric wrench to rotate the hexagonal nut A to drive the bidirectional threaded shaft to rotate. The rotation of the bidirectional threaded shaft will cause the two moving blocks to move relative to each other. The two moving blocks that move relative to each other will push the conical plug block B to move horizontally through the two linkage arms, so that the conical plug block B is inserted into the center hole of the cable drum body. As the conical plug block B continues to move, the cable drum body will drive the two supporting pulleys to slide on the surfaces of the two sliding rods, so that the conical plug block A is passively inserted into the center hole of the cable drum body. Finally, the cable drum body is stably and firmly installed between the two supporting pulleys, the conical plug block A and the conical plug block B.

[0016] When the cable reel body needs to be wound or unwound, the hexagonal nut B is rotated by an electric wrench, and the rotation of the hexagonal nut B drives the worm to rotate and the worm wheel to rotate, and the rotation of the worm wheel drives the winding and releasing adjustment shaft to rotate, and the rotation of the winding and releasing adjustment shaft drives the fixed block to rotate, and the rotation of the fixed block drives the conical plug block B to rotate through two linkage arms, and the rotation of the conical plug block B drives the cable reel body to rotate through the rotatable conical plug block A and two rotatable support pulleys, thereby realizing the winding or unwinding operation of the cable reel body;

[0017] (3) Use an electric wrench to rotate one of the hexagonal nuts C. The rotation of one of the hexagonal nuts C will drive the adjustment spindle and the two bevel gears A to rotate. The rotation of the two bevel gears A will drive the two bevel gears B to rotate and cause the two threaded rods B to rotate. The rotation of the threaded rod B will cause the internal threaded hollow column to move upward on its surface. The upward movement of the internal threaded hollow column will drive the two synchronous adjustment tooth plates on its surface to move upward. The upward movement of the synchronous adjustment tooth plates will drive the transmission gear to rotate. The rotation of the transmission gear will drive the transmission tooth plate to tilt upward. The tilting upward movement of the transmission tooth plate will drive the inverted T-shaped sliding block to tilt upward inside the inverted T-shaped sliding groove. The tilting upward movement of the inverted T-shaped sliding block will drive the adjustment tooth plate to tilt upward. The tilting upward movement of the adjustment tooth plate will drive the adjustment gear to rotate. Finally, the four adjustment gears will rotate synchronously and drive the four threaded rods A to rotate and adjust.

[0018] The four threaded rods A are rotated by rotating the four adjusting gears. The rotation of the four threaded rods A will cause the outer square internally threaded tube to move downward on its surface and inside the inclined square perforation. The downwardly moving square internally threaded tube will drive the rollers to move downward and contact the ground. Finally, the four rollers will prop up the stable base away from the ground. Then, the device is moved by the four rollers to facilitate the movement of the cable reel body. BRIEF DESCRIPTION OF THE DRAWINGS
