[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, and all other embodiments obtained by the person skilled in the art based on the embodiments in the utility model belong to the protection scope of the utility model.

[0022] The embodiment of the utility model:

[0023] As Figs. 1-3As shown, in the embodiment, the auxiliary frame 1 is provided, the auxiliary frame 1 comprises a supporting plate 11, a matching plate 12 is connected to the supporting plate 11 through a connecting rod 13, the supporting plate 11 and the matching plate 12 are both circular, a limiting plate 14 is arranged on the supporting plate 11, the long rotating shaft 3 is inserted into the auxiliary frame 1 through the through hole on the supporting plate 11, the limiting plate 14 is matched with the bearing 31 on the long rotating shaft 3, the matching plate 12 is matched with the puller 2, when the puller 2 is subjected to the pulling force, the bearing 31 is tightly pressed on the limiting plate 14.

[0024] In an embodiment of the utility model, the connecting rod 13 is a screw rod, both sides of the connecting rod 13 and the supporting plate 11 and the matching plate 12 are fixed with nuts, and the distance between the supporting plate 11 and the matching plate 12 can be adjusted according to the actual use.

[0025] In an embodiment of the utility model, the limiting plate 14 and the supporting plate 11 are adjustably and slidably connected, in the embodiment, when the limiting plate 14 is moved into the through hole on the supporting plate 11, the bearing 31 on the long rotating shaft 3 can be supported and limited, when the limiting plate 14 is moved to the side of the supporting plate 11, the long rotating shaft 3 and the bearing 31 thereon can be inserted into the auxiliary frame 1 without interference.

[0026] In the embodiment, adjusting grooves 141 are arranged on the limiting plate 14, the adjusting grooves 141 are arranged in two and symmetrically, fastening bolts 142 are connected through the adjusting grooves 141, the nut diameter of the fastening bolt 142 is greater than the width of the adjusting groove 141, and a threaded hole is arranged on the supporting plate 11 and matched with the fastening bolt.
