Referring to fig. 1-3, when the first positioning block 12 moves to adjust the position of the fixing mechanism 3 in the predetermined direction, the fixing mechanism 3 is guided by the second guiding groove 14 to prevent the fixing mechanism 3 from deviating from the predetermined direction.

In the riveting process, the riveting machine applies downward pressure to the parking pull rod 4 and transmits the downward pressure to the first positioning block 12 through the fixing mechanism 3, as shown in fig. 2 and 3, at this time, the lower surface of the first positioning block 12 is integrally abutted and attached to the side wall of the first guide groove 13, and since the moving direction of the first positioning block is perpendicular to the stress direction, the first positioning block 12 cannot move due to the pressure of the riveting machine, the position of the fixing mechanism 3 in the preset direction cannot be changed, the parking pull rod 4 is fixed, and the riveting quality of the riveting end is good.

In this embodiment, the limiting mechanism 2 includes a taper pin limiting block 21, a fixed limiting block 22 and a sliding limiting block 23 which are matched with each other, the taper pin limiting block 21 can be attached to at least part of the side conical surface of the parking taper pin 43, the parking taper pin 43 is limited in the preset direction, and the fixed limiting block 22 and the sliding limiting block 23 can clamp the riveting end of the parking pull rod 41 in the plane perpendicular to the preset direction.

The moving manner of the sliding limiting block 23 in the abutting direction is the same as that of the fixing mechanism 3 in the preset direction, that is, the second positioning block 25 is driven by the second driving part 24 to move along the third guide groove 26; other realizations of the second driving portion 24 and the second positioning block 25 are also the same as those of the first driving portion 11 and the first positioning block 12, and therefore, the description thereof is omitted.

Because parking pull rod 41 may have slight size deviation, and fixed stopper 22 and slip stopper 23 may appear wearing and tearing scheduling problem in the use, second locating piece 25 is provided with the inclined plane of two different inclinations in this embodiment, it is bigger to be close to the one end gradient that thickness is little, it is lower to be close to the one end gradient that thickness is big, when slip stopper 23 moves to the fixed stopper 22 of butt in order to press from both sides tight parking pull rod 41, support slip stopper 23 by the lower inclined plane of inclination, in order to guarantee that fixed stopper 22 and slip stopper 23 can press from both sides tight parking pull rod 41 all the time, and do not influenced by above-mentioned error.

It should be noted that, for example, as shown in fig. 3, after the parking lever assembly 4 is riveted, the second driving portion 24 needs to be controlled to drive the second positioning block 25 to move to the lowest end, so that the sliding limiting block 23 can move in the opposite direction of the abutting direction to return to the initial position, and the parking lever assembly 4 can be normally taken out. In the process, the sliding limiting block 23 can be moved by a worker manually returning the sliding limiting block; alternatively, the slide stopper 23 may be connected to a circumferential outer position of the fourth guide groove 27 by an elastic member so that the slide stopper 23 returns to the initial position when not subjected to an external force; or a driving structure such as a motor or an air cylinder may be additionally disposed at the right end of the sliding stopper 23 to control the sliding stopper to retract to the initial position.
