As an example, referring to fig. 1 to 4, when the diameter of the tire 100 to be supported becomes larger, the electric telescopic rod is activated, and the electric telescopic rod drives the cone 92 to move upwards along the first direction (i.e., the Y direction in fig. 4), so that the conical surface 921 gradually stretches between the first support portion 632 and the second support portion 642, thereby increasing the distance between the first support portion 632 and the second support portion 642 (i.e., the first support portion 632 moves towards the B direction in fig. 4), the second support portion 642 moves towards the a direction opposite to the B direction in fig. 4), simultaneously the first fixing portion 631 and the second fixing portion 641 also move synchronously (i.e., move back along the X direction in fig. 4), and the first attaching portion 633 and the second attaching portion 643 also move synchronously (i.e., move back along the X direction in fig. 4), so that the first attaching portion 643 and the second attaching portion 633 can completely abut against the inner side of the tire 100 to be supported (i.e., the first sliding groove 631B of the second fixing portion 641 and the second sliding groove 52B of the tire 100, and the second sliding bar 52B of the second fixing portion 641 also abuts against the inner side of the first sliding groove 52 of the tire 52 to be supported, respectively.

As an example, referring to fig. 1 to 4, when the diameter of the tire 100 to be supported becomes smaller, the electric telescopic rod is activated, and the electric telescopic rod drives the cone 92 to move downward along the first direction (i.e., along the Y direction in fig. 4), so that the conical surface 921 is gradually withdrawn between the first support portion 632 and the second support portion 642, thereby reducing the distance between the first support portion 632 and the second support portion 642 (i.e., the first support portion 632 moves toward the a direction in fig. 4, and the second support portion 642 moves toward the B direction opposite to the a direction in fig. 4), and simultaneously the first fixing portion 631 and the second fixing portion 641 move synchronously (i.e., move toward each other along the X direction in fig. 4), and the first engaging portion 633 and the second engaging portion 643 also move synchronously (i.e., move toward each other along the X direction in fig. 4), so that the first engaging portion 643 and the second engaging portion 643 can completely engage the inner side of the tire 100 to be supported, and the first sliding rod 641 and the second sliding rod 641 simultaneously engage the inner side 52 of the tire 100 to be supported, and the sliding groove 52B of the first sliding bar 641 and the second sliding bar 52, respectively, at the two ends of the first bead portion 641 and the inner side 52 to be supported by the sliding bar 52.

For example, referring to fig. 3 and 4, a buffer spring 911 is disposed on the outer surface of the telescopic driving part, one end of the buffer spring 911 is connected with the bottom 922 of the cone, the other end of the buffer spring 911 is connected with one side of the stop lever 20 away from the bottom support 10, and breakage of the electric telescopic rod due to excessive pressure can be effectively prevented by buffer protection of the buffer spring 911.

For example, referring to fig. 1, one end of the buffer spring 911 is fixedly connected to the bottom 922 of the cone, and the other end of the buffer spring 911 is fixedly connected to the side of the stop lever 20 away from the bottom support 10, wherein the fixing connection may be a threaded connection or a welding, so long as the fixing connection is achieved, which is within the scope of the present utility model.

Illustratively, referring to fig. 2 and 3, the second gear 51 is in rolling contact with the bottom support 10. A cover groove 53 is formed in one side of the second gear 51 facing the bottom support 10, a support groove 12 is formed in the side of the bottom support 10 opposite to the second gear 51, and a plurality of balls 13 are connected between the inner wall of the cover groove 53 and the inner wall of the support groove 12. In the operation of the tire embossing apparatus in the embodiment of the present utility model, the friction force between the second gear 51 and the bottom support 10 can be reduced by the plurality of balls 13 rolling on the inner wall of the cover groove 53 and the inner wall of the support groove 12, thereby avoiding friction damage.
