Further, in the actual working condition, when the vehicle 300 moving on the track 200 encounters the car stopper 100 of the present application, the rail wheel of the vehicle 300 is firstly in contact with the movable clip body 1, and the rail wheel drives the car stopper 100 to move synchronously as a whole while pressing the movable clip body 1, so as to urge the movable clip body 1 to move from the release position to the locking position, and in the locking position, the movable clip body 1 and the track 200 are tightly clamped, so that friction force between the two can prevent the movable clip seat 2 from further sliding, and other manual operations are not required in the process, so that the self-clamping of the car stopper is realized, and the car stopper 100 after being fixed forms a barrier to prevent the vehicle 300 from continuously moving on the track 200.
It can be understood that the elastic member 3 connected between the movable card seat 2 and the movable card body 1 can absorb energy generated by collision and extrusion between the movable card body 1 and the rail wheel of the vehicle 300, that is, the elastic member 3 needs to overcome the elastic force brought by the elastic member 3 in the process that the movable card body 1 moves from the release position to the locking position, the elastic member 3 plays a role of buffering, so that the rail wheel of the vehicle 300 and the car stopper 100 are prevented from being impacted in a hard manner due to the fact that the movable card seat 2 is rapidly pressed down to tightly clamp the movable card body 1, thereby prolonging the service life of the car stopper 100, and meanwhile, when the rail wheel of the vehicle 300 leaves the car stopper 100, the energy absorbed by the elastic member 3 can drive the movable card body 1 to move from the locking position to the release position, so that the car stopper 100 is in a detachable state, and the flexibility of using the car stopper 100 is improved.

In other words, the two vertical plates 21 of the movable clamping seat 2 and the partition plate 22 form an "H" structure, the diaphragm plate 22 connected in the middle of the "H" movable clamping seat 2 has a avoidance groove 222 with an upper opening and a lower opening, the avoidance groove 222 is adjacent to one side vertical plate 21 of the movable clamping seat 2, and a portion of the movable clamping body 1 located in the upper groove of the "H" movable clamping seat 2 can penetrate downwards into the avoidance groove 222 to be clamped with the track 200 located in the lower groove of the "H" movable clamping seat 2, so that the car arrester 100 can be locked.
It will be appreciated that the two vertical plates 21 of the movable card holder 2 limit the movement of the movable card body 1 in the left-right direction (the left-right direction as shown in fig. 2), so as to prevent the movable card holder 2 from falling off in the process of moving from the release position to the locking position.
Further, as shown in fig. 2 and 4, the movable card holder 2 further includes a reinforcing side plate 23, the reinforcing side plate 23 is located above the partition 22 and vertically disposed, and the partition 22, the reinforcing side plate 23, and the two vertical plates 21 are connected to enclose a mating cavity, at least part of the movable card body 1 is mated in the mating cavity, that is, the reinforcing side plate 23 is vertically disposed above the partition 22 and connected to the vertical plates 21 located at the left and right sides of the partition 22, thereby enhancing the stability of the structure of the movable card holder 2.

Specifically, when the top plate 11 of the movable clip body 1 contacts with the rail wheel of the vehicle 300, it is pressed downward, and the guide plate 12 is driven to extend into the avoidance groove 222 until being clamped with the rail 200 at the locking position.
Preferably, the width dimension of the top plate 11 is not greater than the spacing distance between the vertical plates 21 on the left and right sides of the movable clamping seat 2, so as to ensure that the guide plate 12 is always attached to the vertical plate 21 adjacent to the avoidance groove 222 when moving downwards, and the guide plate 12 smoothly extends into the avoidance groove 222.
Further, as shown in fig. 2 and 3, the guide plate 12 includes a guide section 121 and a tapered section 122, the tapered section 122 is away from the top plate 11 relative to the guide section 121, an inner side surface of the tapered section 122 extends obliquely outward in a direction away from the top plate 11, and in the locked position, the tapered surface is fitted with an end surface of the rail 200.
