[0022] Furthermore, in the present embodiment, a height-adjustable driving block 6 is arranged in the middle of the support disk 3, and the driving block 6 is connected to the support part 4 through a hinge plate 7. In order to ensure the stability of the movement of the support part 4, it is preferred that each support part 4 is provided with two upper and lower hinge plates 7, and the two hinge plates 7 are arranged in parallel; in order to enhance the stability of the overall structure of the support part 4, a reinforcement block 8 is also arranged on the inner side of each support part 4, and the hinge plate 7 is hinged on the reinforcement block 8; the support part 4 is slidably arranged on the support disk 3, and when it is necessary to adjust the diameter of the manufactured retaining ring, the driving block 6 can be controlled to move up and down, thereby driving the hinge plate 7 to push the support part 4 to move along the support disk 3, and the structure is simple and easy to operate; the driving block 6 can be controlled by a cylinder and can also be controlled and adjusted by a threaded screw; In the embodiment, a threaded screw 9 is used to control the driving block 6 to move up and down; specifically, a threaded screw 9 is rotatably provided on the support disk 3, and a supporting sleeve 10 is sleeved on the outside of the threaded screw 9. One end of the threaded screw 9 is rotatably connected to the support disk 3 and the other end is rotatably connected to the supporting sleeve 10. The driving block 6 is threadedly connected to the threaded screw 9, and an adjustment groove is provided on the side of the supporting sleeve 10 in the vertical direction. The hinge plate 7 is hinged to the driving block 6 through the adjustment groove; since the position of the support part 4 does not need to be adjusted frequently, the threaded screw 9 is set to a manual adjustment mode in this embodiment, and it is preferred that the top end of the threaded screw 9 is set through the top of the supporting sleeve 10, and a driving groove 11 with a polygonal cross section is provided at the top of the threaded screw 9, so as to facilitate the insertion of tools or electric drills to drive the threaded screw 9 to rotate. In specific use, the threaded screw 9 is controlled to rotate, and the driving block 6 is driven to move up and down, thereby completing the position adjustment operation of the support part 4.

[0023] Furthermore, in this embodiment, a slide groove 12 is provided through the support plate 3, and a slide rod is provided at the bottom of the support portion 4. After the slide rod passes through the slide groove 12, it is connected to the limit plate 13 located at the bottom of the support plate 3; the setting of the limit plate 13 can limit the support portion 4 in the vertical direction, so as to avoid the situation that the support portion 4 is pushed to move by the partial upward force during the process of the steel bar being wound on the support portion 4, thereby ensuring the stability of the support portion 4 after the position is adjusted. In addition, in this embodiment, the positioning rod 5 can be adjusted on the limit plate 13 after passing through the slide groove 12 at the corresponding position. The adjustable setting of the positioning rod 5 on the limit plate 13 can adjust the distance between the positioning rod 5 and the support portion 4, so as to provide a matching limit space for its end when the steel bar is wound.

[0024] A positioning rack 14 is provided at the bottom of the support plate 3 on both sides of each slide slot 12, and a ratchet 15 meshing with the positioning rack 14 is elastically hinged on the limit plate 13. Through the meshing of the ratchet 15 and the positioning rack 14, the adjusted support part 4 can be provided with a positioning limit, sharing the force acting on the hinge plate 7 when the steel bar is wound, and ensuring the stability of the support part 4 during the steel bar winding process. When working, the ratchet 15 can only move gradually along the teeth on the positioning rack 14 as the support part 4 moves toward the outer edge of the support plate 3, and the ratchet 15 will abut against the teeth when the support part 4 moves in the opposite direction to the middle of the support plate 3, thereby playing a role in positioning the support part 4; when the support part 4 needs to be adjusted to the middle of the support plate 3, the ratchet 15 needs to be flipped up to separate it from the positioning rack 14 to avoid hindering the movement of the support part 4.

[0025] Preferably, the pawl 15 is elastically hinged at the bottom of the limit plate 13 through a hinge shaft and a torsion spring, and a positioning gear 16 is provided on one end of the hinge shaft extending outward; a driving rod 17 is elastically provided on one end of the limit plate 13 close to the outer edge of the support plate 3, and the driving rod 17 can be positioned and connected with the limit plate 13, so that the state of the pawl 15 can be adjusted by positioning or releasing the positioning of the driving rod 17 and the limit plate 13, thereby ensuring the smooth adjustment of the position of the support part 4. A driving rack 18 that can mesh with the positioning gear 16 for transmission is provided at the end of the driving rod 17. In the initial state, the driving rack 18 does not contact the positioning gear 16 to avoid affecting the movement adjustment of the support part 4 toward the outside of the support plate 3; when the support part 4 needs to be adjusted toward the inside of the support plate 3, the driving rod 17 can be pushed, and the driving rack 18 at the end of the driving rod 17 will mesh with the positioning gear 16 for transmission, driving the pawl 15 to flip, thereby separating the pawl 15 from the positioning rack 14, eliminating the adjustment obstacle to the support part 4, and at this time, the driving rod 17 is positioned and connected with the limit plate 13; after the adjustment of the support part 4 is completed, the connection between the limit plate 13 and the driving rod 17 is released, and the pawl 15 is hinged by a torsion spring, and under the restoring force of the torsion spring, the pawl 15 is driven to re-engage with the positioning rack 14.

[0026] Specifically, a driving groove 21 is provided on the limiting plate 13, and the driving rod 17 is arranged in the driving groove 21 by a spring; positioning springs 19 are provided on both sides of the driving rod 17, and positioning convex heads 20 are provided at the ends of the positioning springs 19, and positioning grooves for receiving the positioning convex heads 20 are provided on the inner walls on both sides of the driving groove 21; when the driving rod 17 is pushed to move so that the pawl 15 is separated from the positioning rack 14, the positioning convex heads 20 enter the positioning grooves to realize the positioning between the driving rod 17 and the limiting plate 13, and when the positioning between the limiting plate 13 and the driving rod 17 needs to be released, the positioning springs 19 can be pressed to make the positioning convex heads 20 move out of the positioning grooves, and the driving rod 17 is reset under the restoring force of the spring. In this embodiment, the ends of the positioning springs 19 can also be set as teeth, and tooth plates meshing with the teeth are provided on the inner walls on both sides of the driving groove 21, and the positioning between the driving rod 17 and the limiting plate 13 is realized by meshing with each other.

[0027] Furthermore, in this embodiment, the limiting part 2 includes a limiting bracket 2-1, on which a roller 2-2 is rotatably arranged, and the rotating arrangement of the roller 2-2 can reduce the friction generated between the steel bars when they come into contact with the supporting platform 1 during the winding process; wherein the limiting bracket 2-1 is adjustably arranged on the supporting platform 1, so that as the position of the supporting part 4 is adjusted, the position of the limiting part 2 can be matched and adjusted to ensure that there is an adaptive spacing between them; specifically, an adjustment groove is arranged on the supporting platform 1, and the supporting frame is fixed in the adjustment groove by bolts.

[0028] When the utility model is used, the position of each support part 4 is first adjusted according to the diameter of the steel cage; then when winding the steel bar, the steel bar is placed in the space between the support part 4 and the positioning rod 5, the motor is turned on to drive the rotation of the support plate 3, and the steel bar is orderly wound outside the support part 4 under the rotation of the support plate 3 and the limit blocking of the limit part 2. After the whole steel bar is wound, the motor is turned off to stop the rotation of the support plate 3, and the whole steel bar guard ring after winding is removed. When making the steel cage, the steel bar guard ring can be wound around the outside of the steel skeleton. This device greatly improves the processing efficiency. At the same time, since the support part 4 is arranged along the circumference of the support plate 3, the roundness of the guard ring can be guaranteed and the processing quality of the guard ring can be improved. In addition, the adjustable setting of the support part 4 on the support plate 3 can meet the production requirements of guard rings of various sizes, expand the scope of use, and enhance practical performance.
