Therefore, two ends of the supporting spring 4 are respectively connected with the traction rod 1 and the mounting base plate 2, and the coupler is further kept to be within a set range from the plane of the track, so that the purpose of improving the using effect of the self-resetting traction coupler is achieved.
It should be noted that, the traction rod 1 and the mounting base plate 2 are both provided with a boss 41; the two ends of the supporting spring 4 are respectively connected and fixed with the corresponding bosses 41 on the installation base plate 2 or the traction rod 1, and the arrangement of the bosses 41 can realize the purposes of stably installing the supporting spring 4 and improving the using effect of the coupler.
Specifically, when the coupler head 3 of the coupler is not mounted on the traction rod 1, the elastic component can support the outer end part of the traction rod 1 to incline upwards, and after the coupler head 3 of the coupler is mounted on the traction rod 1, the traction rod 1 can swing under the gravity action of the coupler head 3 of the coupler and descend to a horizontal state, so that the traction rod 1 can conveniently perform traction action; when the traction work is finished, the coupler head 3 of the coupler is disassembled, and the traction rod 1 can be inclined upwards again under the action of the elastic component.
More specifically, the elastic member is preferably arranged at the bottom of the rear end of the traction rod 1 in a compressed state; of course, the elastic component can also be arranged at the top of the rear end of the traction rod 1 and is in a stretching state; the arrangement mode of adjusting the angle of the traction rod 1 can be achieved, and is not limited to the mode given in the embodiment.
