Among them, the connection between the winding column and the driving structure and the bracket is divided into a fixed type and a detachable type. The detachable type is generally bolt fixation and the position fixation of the piston rod of the cylinder.

A plurality of cross teeth 36 are fixedly connected to one side of the rotating column 2 close to the adjusting column 34. The locking teeth 35 and the cross teeth 36 are arranged in an array on the surfaces of the adjusting column 34 and the rotating column 2, and the locking teeth 35 and the cross teeth 36 are engaged with each other.

[0037] It should be noted that both the locking teeth 35 and the cross teeth 36 are triangular and are annularly arranged at one end of the structure. After the corresponding teeth are engaged, the structural positions fixed on the tooth surfaces are relatively fixed.

[0038] A plurality of rotating bearings are fixedly connected inside the bearing column 33. The inner rings of the rotating bearings are all clamped with a base rod 37. A contact rod 38 is threadedly connected to the surface of the base rod 37.

[0046] In the actual application process of this cable winding and unwinding rotating device, by arranging a movable bearing column 33 on the surface of the rotating column 2 rotating on the surface of the support frame 1, and arranging an adjustable column 34 that can rotate on the side of the bearing column 33 close to the rotating column 2, the rotation of the adjustable column 34 drives the rotation of the base rod 37 inside the bearing column 33. Furthermore, the contact rod 38 moves away from the bearing column 33, and the contact block 312 rotates towards the contact rod 38, reducing the distance between the two. The winding column located between the two can be clamped, achieving the relative position fixation of the winding column and the rotating column 2. Furthermore, the winding column can be fixed by rotating the adjustable column 34 once, which is faster and more convenient. Moreover, the position of the contact rod 38 can be changed. It can rotate downward when the diameter of the winding column is small, directly clamping the side of the winding column, and thus can be applicable to more types of winding columns;

[0047] In some specific implementation schemes, the above-mentioned moving component includes a rotating groove 41 and a limiting groove 42 opened on the surface of the bearing column 33;

[0048] It should be noted that both the rotating groove 41 and the limiting groove 42 are cylindrical grooves. The diameter of the limiting groove 42 is larger than that of the rotating groove 41, and the two are connected. The limiting groove 42 is closer to the adjustable column 34;

[0049] A connecting column 43 is fixedly connected to the side of the contact rod 38 close to the bearing column 33, and a connecting rod 44 is slidably connected inside the connecting column 43;

[0050] The connecting rod 44 is inserted into the inside of the bearing column 33;

[0051] A moving gear 45 is fixedly connected to the side of the connecting rod 44 away from the contact rod 38, and a limiting gear 46 is slidably connected inside the bearing column 33;

[0052] The limiting gear 46 meshes with the moving gear 45, and the width of the limiting gear 46 is greater than the width of the moving gear 45;

[0054] It should be noted that the width of the limiting gear 46 is greater than the total width of the limiting teeth 47 and the moving gear 45, that is, the limiting gear 46 can mesh with the limiting teeth 47 and the moving gear 45 at the same time;

[0055] In a further embodiment, the above-defined price-setting group includes a limit cover 51 slidably disposed on the surface of the support frame 1. A limit spring (not shown in the figure) is fixedly connected between the limit cover 51 and the support frame 1. A protruding tooth (not shown in the figure) is fixedly connected to the end of the rotating block 31 away from the transfer rod. A fitting tooth (not shown in the figure) is fixedly connected to the side of the limit cover 51 close to the protruding tooth. The protruding tooth is engaged with the fitting tooth;

[0056] The working principle of the present utility model: Place the winding column on the surface of the bearing column 33 through the groove on its surface corresponding to the position of the base rod 37. Then, move the bearing column 33 towards the winding column through the telescopic rod 32. At this time, the locking teeth 35 and the cross teeth 36 are disengaged. Rotate the adjusting column 34. The rotation of the adjusting column 34 drives the synchronous tooth 315 to rotate, prompting the synchronous gear 313 to rotate. The rotation of the synchronous gear 313 drives the base rod 37 to rotate, prompting the contact rod 38 on the surface of the base rod 37 to slide towards the surface of the winding column. The rotation of the base rod 37 drives the worm 310 to rotate. The rotation of the worm 310 prompts the worm wheel 311 to rotate, driving the contact block 312 to rotate towards the contact rod 38. At this time, the contact rod 38 and the contact block 312 clamp the winding column, realizing the fixation of the position of the winding column. Restore the position of the bearing column 33, and then rotate the rotating block 31. Perform the same operation to fix the other end of the winding column and the position of the rotating block 31, that is, complete the installation of the winding column; When fixing a winding column with a smaller size, it is necessary to first slide the limit gear 46 outwards, prompting the surface of the limit gear 46 to disengage from the surface of the limit tooth 47. At this time, rotate the contact rod 38. The contact rod 38 drives the base block 39 and the contact block 312 to rotate downwards. After rotating to a suitable position, press the limit gear 46 and restore the limit gear 46 to repeat the operation of fixing the winding column to complete the fixation.

[0057] The above embodiments are only used to illustrate the technical method of the present utility model and not to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present utility model.
