Its power source is directly driven by handwheel 1 manual or servo motor. When the first section of threaded screw 14 is driven to rotate, driven by the intermediate shaft 16, the second section of threaded screw 15 will also rotate at the same time. Since the first section of threaded screw 14 and the second section of threaded screw 15 have opposite directions of rotation, the traveling directions of the two supporting frames connected thereto are opposite, that is, they approach or move away from each other at the same time. This kind of structure can realize the way that one side drives the other side to adjust synchronously. the

As shown in Figure 7, an embodiment, the transmission mechanism is a fixed gear double-sided rack structure, including a fixed gear 17, a first rack 18 and a second rack 19, the first rack 18 and the second rack Two racks 19 are all engaged with the fixed gear 17, the first rack 18 and the second rack 19 are located on opposite sides of the fixed gear 17, and are parallel to each other, the fixed gear 17 passes through The bearing seat is connected with the cavity, and the first rack 18 and the second rack 19 are respectively connected with one support block 2 . Its power source is directly driven by handwheel 1 manual or servo motor. When the fixed gear 17 is driven to rotate, the first rack 18 and the second rack 19 on both sides can be driven to advance simultaneously. Since the first rack 18 and the second rack 19 are located on opposite sides of the fixed gear 17, And the first rack 18 and the second rack 19 are parallel to each other, so driven by the fixed gear 17, the direction of travel of the first rack 18 and the second rack 19 is opposite, so the two supporting frames connected to it The direction of travel is opposite, that is, approaching or departing at the same time. This kind of structure can realize the way of synchronous regulation. the

While the diameter of the rocket body 10 has various specifications, the specifications of the length of the rocket body are more numerous. Therefore, the adjustable rolling mechanism used for the rocket body of various diameters needs to be fixedly placed on the fixed support 7 or the mobile support 13 that can move along the radial direction of the rocket body. way to accommodate the difference in the length of the rocket body. the
