description The utility model relates to a connecting device between a spreader and pushing equipment. A push back rack (4) hinged with a push back device (7) is hinged with a spreader (6) through a cross pin (2); a middle connecting rack (3) is penetrated and connected with the spreader (6) through a center pin (13); the middle connecting rack (3) is also provided with an arc-shaped groove (12). The cross pin (2) is penetrated and connected between a lateral plate (10) which is connected into integration with the middle connecting rack (3) and a ribbed slab (11) which is connected into integration with the push back rack (4). The connecting device not only overcome the shortage of the original rigid connection but also causes the component to move randomly, and particularly can ensure the planeness and the cross slope of the road paving, and furthermore, the construction quality is improved.
