Specifically, the left and right sides of transition support 2 are located respectively to left connecting seat 41 and right connecting seat 42, and left connecting seat 41 can dismantle with left side support 211 and protection crossbeam 3 simultaneously and be connected, and right connecting seat 42 can dismantle with right side support 212 and protection crossbeam 3 simultaneously and be connected to can dismantle between realization transition support 2 and the protection crossbeam 3 and be connected, so that the dismouting operation between transition support 2 and the protection crossbeam 3. It can be understood that, in the collision process, the protection crossbeam 3 is the part of direct atress, and impaired relatively is more serious, need change when necessary, and the protection crossbeam 3 can be dismantled with transition support 2 and be connected to be convenient for change protection crossbeam 3. Wherein the detachable connection is a bolt connection. Alternatively, the left and right connection holders 41 and 42 are L-shaped or T-shaped plate-shaped structures.

Above combine the figure to explain in detail the technical scheme of the utility model, carried out structural improvement to the protector of current commercial car, improved the intensity of front and side, effectively improved commercial car protective structure's whole protective capacities and stability.
