The specific embodiment

The utility model is described in further detail with embodiment with reference to the accompanying drawings below:

As Fig. 1, shown in 2, a kind of trailer traction device of the present utility model, towing hook (shown in Figure 1) and hook (shown in Figure 2) two parts of comprising flexible connection, towing hook comprises an annulus 3, two hold-down arms 5 of captiveing joint with this annulus 3, and these two hold-down arm 5 lower ends are fixed into one by a pull bar 1, the two ends of pull bar 1 respectively with the flexible connection of a fixed bearing 6, and rotate along this fixed bearing 6 in use, specifically, pull bar 1 two ends are provided with position-limited trough, be respectively equipped with a circular hole on the fixed bearing 6, the circular hole wall of this circular hole snaps in this position-limited trough, so pull bar 1 can rotate relative to this fixed bearing 6, and two hold-down arms 5 are respectively equipped with a locating dowel pin 2, and its curved surface that is provided with along fixed bearing 6 is stuck in when coming back rotation and towing hook on even keel in the curved surface groove on the fixed bearing 6; Hook comprises base 8, the pedal part, base 8 comprises an assembled portion, it is connected with a pedal mounting portion by a curved surface connecting bridge, one bossing 9 that is provided with groove is connected with the assembled portion inner face, this assembled portion, the curved surface connecting bridge, the pedal mounting portion, bossing designs for one, the tread portion branch comprises pedal 10, the pedal support 11 that connects this pedal 10, this pedal support 11 passes the pedal mounting portion and is connected with it by bearing pin 12, and be provided with pull back spring in the pedal support 11, not during push down on the pedal 10, pedal support 11 contacts with the interior face portion of bossing 9 and forms enclosed cavity with base 8, and when connecting two cars, towing hook is 90 degree levels, two cars are collided, towing hook annulus 3 clashes into pedal support 11 automatically by the spigot surface 14 of hook bossing 8, pull back spring distortion in the pedal support 11, and annulus 3 slips into hook inner sealing cavity automatically, pull back spring plays locking action, finish being connected of towing hook and hook, when pedal 10 not, annulus remains mode of operation!
