Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 3, this embodiment provides a swing arm drive arrangement on sley bar, including connecting pole 1, wearing to establish connect pole 1 interior adjustable length's connecting rod 2 and install the sley bar seat 3 of connecting rod 2 free end, the upper end of connecting rod 2 is equipped with U-shaped seat 4, the upper end of two curb plates 41 of U-shaped seat 4 is equipped with the installation ring body 42 respectively, and two installation ring bodies 42 are parallel to each other, rotationally is equipped with a pivot 5 in two installation ring bodies 42, pivot 5 rotationally locates in the installation ring body 42 through bearing 6. The position department that lies in between the both sides board 41 in the pivot 5 is equipped with through-hole 51, be equipped with on the sley bar seat 3 and paste the sunken 31 of tight complex arc with the pivot, be equipped with mounting hole 32 on the sunken 31 of arc, the mode that through-hole 51, mounting hole 32 were worn to establish through locking bolt 7 in pivot 5 links to each other with sley bar seat 3 locking.
