When the transmission mounting block 26 is adjusted by the electric push rod 34, the electric push rod 34 pushes the transmission mounting block 26 to be matched with the transmission block 29, and then the transmission mounting block can be automatically extended and reset without influencing the reset of the transmission mounting block 26.

As shown in fig. 14, a plurality of limiting blocks 45 are circumferentially and uniformly installed on the side surface of the installation sliding block 6 of the installation assisting mechanism 3, which is located outside the bracket 2, as shown in fig. 13, a sliding groove 48 is formed on the first installation sleeve 19, two third sliding grooves 52 are symmetrically formed in the sliding groove 48, one end of the limiting sliding block 47 is provided with a third inclined surface 46, two third sliding blocks 53 are symmetrically installed at the other end of the limiting sliding block 47, the limiting sliding block 47 is installed in the sliding groove 48 through the sliding fit of the two third sliding blocks 53 and the two third sliding grooves 52, a second spring 51 is installed between the limiting sliding block 47 and the sliding groove 48, and the second spring 51 is a compression spring.

In the invention, the adjusting cylinder 40 returns to one side close to the mounting slide block 6 after sliding once around the guide rail 41, the spiral spring 49 applies a starting auxiliary force to the winding roller 1 once in the process, and the winding roller 1 correspondingly pays off once; after the adjusting cylinder 40 has been slid into the track on the side close to the mounting slide 6 via the transition region 44 on the guide rail 41, the transmission mounting block 26 is driven back.

The specific working process is as follows: when the support frame designed by the invention is used, firstly, the winding roller 1 is lifted and moved to the middle of the support frame 2 through auxiliary equipment, then the mounting shaft 5 is inserted into the side which is not provided with the auxiliary mechanism 3, so that the transmission key 55 on the mounting shaft 5 is matched with the mounting sliding block 6 which is not provided with the auxiliary mechanism 3 through a key and a key slot, then the mounting shaft 5 passes through the winding roller 1 and is finally inserted into the second mounting sleeve 27, so that the mounting shaft 5 is matched with the second mounting sleeve 27 through a key and a key slot; the mounting shaft 5 is matched with the winding roller 1 through a key and a key groove; in this state, the two mounting sliders 6 are positioned on the upper sides of the two side brackets 54 by the first springs 17; the adjusting cylinder 40 mounted on the transmission mounting block 26 is matched with the track on the side, close to the mounting slider 6, of the guide rail 41 but does not slide in, the limiting block 32 limits the sliding of the adjusting cylinder 40 towards the track on the side, far away from the mounting slider 6, of the guide rail 41, namely when the auxiliary mechanism 3 is seen from the direction of the rocker 28, the counterclockwise rotating direction of the third mounting sleeve 35 on which the transmission mounting block 26 is mounted is limited, and the counterclockwise rotating direction of the outer end of the volute spiral spring 49 is limited.

Then the rocker 28 drives the second mounting sleeve 27 to rotate, the second mounting sleeve 27 rotates to drive the mounting shaft 5 to rotate, the mounting shaft 5 rotates to drive the winding roller 1 to rotate clockwise to wind the cable on the winding roller 1, the winding roller 1 becomes heavy along with the increase of the cable on the winding roller 1 during the winding process, and drives the two mounting sliders 6 to move downwards, when the two mounting sliders 6 move downwards, the mounting slider 6 of the mounting auxiliary mechanism 3 drives the first mounting sleeve 19, the transmission 22, the seventh gear 20, the fifth gear 21 and the sixth gear 23 mounted thereon to slide downwards relative to the corresponding side bracket 54, when the sixth gear 23 moves downwards relative to the corresponding side bracket 54, the sixth gear 23 rotates under the action of the fixed rack 25 fixedly mounted on the side bracket 54, and the sixth gear 23 rotates to drive the input shaft of the transmission 22 to rotate, the input shaft of the transmission 22 rotates, the transmission 22 changes speed and then drives the output shaft of the transmission 22 to rotate, the output shaft of the transmission 22 rotates to drive the fifth gear 21 to rotate, the fifth gear 21 rotates to drive the seventh gear 20 to rotate, the seventh gear 20 rotates to drive the first mounting sleeve 19 to rotate, the inner end of the spiral spring 49 rotates anticlockwise, and the spiral spring 49 stores force.

When paying off is needed, the transmission mounting block 26 is manually pulled or the transmission mounting block 26 is pushed through the electric push rod 34, so that when the transmission mounting block 26 slides towards one side far away from the mounting slide block 6, the adjusting cylinder 40 mounted on the transmission mounting block 26 moves from one side close to the mounting slide block 6 to the other side to be matched with one side of the guide rail 41 far away from the mounting slide block 6, and the limiting block 32 loses the limiting effect on the adjusting cylinder 40; at this time, when the auxiliary mechanism 3 is seen from the direction of the rocker 28, because the first mounting sleeve 19 mounted at the inner end of the spiral spring 49 is limited by the limiting fixture block 45, and the limiting block 32 limiting the outer end of the spiral spring 49 loses the limiting, the outer end of the spiral spring 49 is released at this time, and the outer end of the spiral spring 49 releases to apply a driving force of anticlockwise rotation to the third mounting sleeve 35 mounted with the spiral spring 49; meanwhile, in the sliding process of the transmission mounting block 26, after the adjusting cylinder 40 mounted on the transmission mounting block 26 is matched with the track on the side, far away from the mounting slider 6, of the guide rail 41, the end, not provided with the adjusting cylinder 40, of the transmission mounting block 26 also moves to the position matched with the transmission block 29 mounted on the second mounting sleeve 27, in this state, when the outer end of the spiral spring 49 releases the rotating force applied to the third mounting sleeve 35, the rotating force is transmitted to the second mounting sleeve 27 through the matching of the transmission mounting block 26 and the transmission block 29, and the second mounting sleeve 27 transmits the rotating force to the mounting shaft 5, so that a certain auxiliary effect is provided for the rotation starting of the winding roller 1.

The adjusting cylinder 40 returns to the side close to the mounting slide block 6 after sliding once around the guide rail 41, and the spiral spring 49 applies a starting auxiliary force to the winding roller 1 in the process, and the winding roller 1 correspondingly pays off once; after the adjusting cylinder 40 has been slid into the track on the side close to the mounting slide 6 via the transition region 44 on the guide rail 41, the transmission mounting block 26 is driven back.
