[0030] On the basis of embodiment one, as Figures 1-3As shown, the two sides of the main frame 1 are slidably installed with slide rods 403 through mounting plates 401, the back of the slide rods 403 is fixedly installed with brake plates 402 used in cooperation with the wheels 101, the front of the slide rods 403 is fixedly installed with push plates 4, the top of the push plates 4 is fixedly installed with transmission rods 405, the top of the transmission rods 405 is fixedly installed with contact rods 406 extending to the front of the main frame 1, the back of the connecting male head 301 is fixedly installed with driving rods 303 used in cooperation with the contact rods 406.

[0031] In use, when the tractor decelerates and brakes, the connecting male head 301 will be inserted into the connecting female head 2 deeper due to inertia, and the driving rods 303 at the back of the connecting male head 301 will be in contact with the contact rods 406 extending into the connecting female head 2, and will push the contact rods 406 backward, the contact rods 406 will transmit the pushing force to the two groups of push plates 4 through the transmission rods 405, the slide rods 403 at the back of the push plates 4 are slidably installed on the mounting plates 401, and the slide rods 403 are fixedly installed with brake plates 402 inside, so that the brake plates 402 can be pushed backward through the contact rods 406, the transmission rods 405 and the slide rods 403, so as to be in contact with the wheels 101 to slow down, achieving the function of synchronous deceleration of the mine car during the deceleration of the tractor, through the synchronous deceleration of the mine car, the inertia during overall deceleration can be reduced, the deceleration distance can be shortened, the mine car can be quickly parked, collision or rollover can be avoided, and safety can be improved, when the tractor retracts the mine car, the connecting male head 301 is repositioned to the front of the connecting female head 2 inside through the pulling force, so as to end the brake deceleration of the mine car, and facilitate the normal movement of the mine car.

[0032] As shown in Figure 1 the outer wall of the slide rod 403 is sleeved with a second reset spring 404, and the second reset spring 404 is in contact with the front of the mounting plate 401 and the back of the push plate 4 respectively.

[0033] In use, the second reset spring 404 can elastically support the push plate 4, and after the tractor ends braking, the second reset spring 404 elastically resets the push plate 4 to the original position, so as to separate the brake plate 402 from the wheel 101, avoiding the case that the brake plate 402 contacts the wheel 101 to increase resistance when the mine car is normally running, and ensuring the smoothness of the mine car during transportation.

[0034] As shown in Figure 1 the top of the pin rod 202 is fixedly installed with a limiting plate 203, and the top of the limiting plate 203 is fixedly installed with a pull rod 204.
