[0025] An auxiliary assembly 5 is arranged on the end of the cross-seat body 1 close to the plug shaft 3, and the auxiliary assembly 5 can limit the position of the plug shaft 3. The auxiliary assembly 5 includes a sliding cylinder 51, a fixed ring 52, a second spring 53, a double-ball head rod 54 and a spherical convex block 55. The sliding cylinder 51 is slidably arranged on the cross-seat body 1, the fixed ring 52 is fixedly installed on the cross-seat body 1, both ends of the second spring 53 are fixedly connected to the fixed ring 52 and the sliding cylinder 51 respectively, the double-ball head rod 54 is slidably arranged on the cross-seat body 1, the sliding cylinder 51 is fixedly installed on the side wall of the inner cavity of the sliding cylinder 51, a groove body matching with the end of the double-ball head rod 54 is opened on the plug shaft 3, and the shape of the groove body is circular. In the initial static state, the spherical convex block 55 contacts the double-ball head rod 54, further improving the coordination of the components in the whole device, so as to cooperate with each other to meet the actual use requirements.

[0026] Working principle: A plug shaft 3 inserted into the cross base body 1 is fixed on the trowel 2, and the three form the cross base structure of the troweling machine. The movable cylinder 41 rotates on the cross base body 1, the rotating cylinder 42 moves on the cross base body 1, and a stop block 43 for enhancing friction is arranged on the surface and fixed on the rotating cylinder 42. Both ends of the connecting rod 44 are movably connected to the movable cylinder 41 and the rotating cylinder 42 respectively. The connecting ring 45 is rotatably arranged on the stop block 43, and the connecting ring 45 is also connected to the cross base body 1 through the first spring 46. Therefore, the connecting ring 45 is in a slidable state inside the cross base body 1. The linkage gear 47 is fixed on the threaded cylinder 48. At the same time, both the linkage gear 47 and the threaded cylinder 48 can rotate inside the cross base body 1. The linkage gear 47 is also meshed with the annular gear 410 fixed on the movable cylinder 41. The screw 49 is arranged inside the threaded cylinder 48 in a threaded connection manner, and the screw 49 is also in threaded connection with the plug shaft 3. Therefore, when the rotating cylinder 42 is pushed downward so that the stop block 43 does not contact the cross base body 1, the rotating cylinder 42 can be rotated. Under the connection of the connecting rod 44, the movable cylinder 41 rotates synchronously. Also, under the transmission of the annular gear 410 and the linkage gear 47, the threaded cylinder 48 rotates, causing the screw 49 to move downward while rotating itself, so as to limit the plug shaft 3 inside the cross base body 1 through its own thread. After the rotating cylinder 42 is released, under the action of the first spring 46, it returns to the initial state, and the stop block 43 contacts the cross base body 1 again to limit the movement of the entire structure.

[0027] The sliding cylinder 51 slides on the cross base body 1. The sliding cylinder 51 is also connected to the fixed ring 52 fixed on the cross base body 1 by using the second spring 53. The double ball head rod 54 slides on the cross base body 1. The spherical convex block 55 is fixed on the inner cavity wall of the sliding cylinder 51 and contacts the double ball head rod 54. And a groove matching with the double ball head rod 54 is arranged on the plug shaft 3. Therefore, before using the fastening assembly 4 for connection, the sliding cylinder 51 is pushed so that the spherical convex block 55 does not contact the double ball head rod 54. At this time, the double ball head rod 54 can slide on the cross base body 1. After the plug shaft 3 is inserted into the cross base body 1, the sliding cylinder 51 is released. Under the action of the second spring 53, the spherical convex block 55 contacts the double ball head rod 54 again, so as to squeeze the other end of the double ball head rod 54 into the groove inside the plug shaft 3, thereby limiting the position of the plug shaft 3 and facilitating the operation of the fastening assembly 4.
