The utility model discloses a kind of power transmission and steering connecting structure of tractor transport unit, including traction outer frame, traction inner frame, fork type drawbar, double ball cage constant velocity universal joint, transmission shaft, drawbar sleeve, double cross universal joint, transmission assembly and transmission shaft universal joint, fork type drawbar includes fork type end and drawbar, the traction outer frame is hinged with traction inner frame, and is connected with tractor head's transmission case, the traction inner frame is hinged with the fork type end of fork type drawbar, double ball cage constant velocity universal joint is installed in the cavity formed by traction inner frame and fork type end, between the transmission shaft and transmission assembly is connected by double cross universal joint. The utility model passes through using double ball cage constant velocity universal joint, can make tractor group more safe when turning angle is larger;By increasing shift mechanism, tractor group can have greater driving force.

This invention relates to the field of welding torch wire feeding mechanism technology, specifically a welding torch wire feeding mechanism with freely adjustable angle. It includes a wire stabilization mechanism, a lifting assembly mounted outside the wire stabilization mechanism and mounted on the welding torch nozzle, a wire delivery mechanism mounted on the wire stabilization mechanism, a lateral angle adjustment mechanism mounted on the wire stabilization mechanism, and four sets of alignment components disposed on the wire stabilization mechanism and the wire delivery mechanism. The wire stabilization mechanism includes a sleeve. By fixing the lifting assembly to the welding torch nozzle and installing the wire stabilization mechanism parallel to the nozzle within the lifting assembly, and using the lateral angle adjustment mechanism to control the lateral angle change of the wire delivery mechanism, the welding wire extending from the wire delivery mechanism can be effectively angled. This provides an unobstructed path for wire delivery at different angles according to the tilt state of the welding torch and the workpiece.
