Swift current car device is prevented to cutting vehicle normal position

The utility model relates to a swift current car device is prevented to cutting vehicle normal position, including the corresponding girder of back tip of cutting vehicle automobile body, girder welding lot is the upside down spring board of 90 " P " shape of up time needle, and this spring board meshes with the spring board that another piece is anticlockwise upside down 90 " P " shape mutually,and the spring board welding that should be anticlockwise upside down 90 " P " shape is in cutting vehicle automobile body rear end, because the spring board has fine elasticity, the spring board meshes with the spring board easily mutually very much, the dead cutting vehicle state of lock of formation. Avoided causing the phenomenon of the automatic swift current car of cutting vehicle because the motor band -type brake postpones attonity even, ensured cutting vehicle's normal operating, reduced manufacturing cost, had simple structure's characteristics. 本实用新型涉及种切割车原位防溜车装置，包括切割车车体的后端部相对应的大梁，大梁焊接块呈顺时针倒转90°"P"形的弹簧板，该弹簧
