A docking block 804 is provided on the side of the inner splint 9 close to the outer splint 7. The insert rod 803 is slidably connected in the built-in groove of the outer splint 7. The insert rod 803 is connected to the pull rod 802 on the side close to the outside of the outer splint 7. A supporting spring 801 is provided above the insert rod 803 and the pull rod 802. The supporting spring 801 is located in the built-in groove of the outer splint 7. A docking groove 806 is provided on the side of the outer splint 7 close to the docking block 804. Slots 805 are provided on both sides of the docking block 804 close to the insert rod 803. The cross-sectional shape of the docking block 804 and the docking groove 806 are both "T"-shaped. The side of the inner splint 9 away from the outer splint 7 is provided with serrated bars distributed at equal intervals.

[0024] During specific implementation, since the clamping plate of the clamping claw will wear out after a long period of use and needs to be replaced with a new clamping plate, after the inner clamping plate 9 is worn, the pull rod 802 can be pulled to both sides so that the pull rod 802 drives the insertion rod 803 to disengage from the slot 805 and squeeze the support spring 801, and then the inner clamping plate 9 is pulled outward so that the inner clamping plate 9 drives the docking block 804 to slide to one side in the docking groove 806.

[0025] See also Figure 1-Figure 3A supporting mechanism 5 is installed on both sides of the support plate 1 away from the first fixed plate 4, and the supporting mechanism 5 includes a second fixed plate 501, a connecting plate 502, a first electric telescopic rod 503, a second electric telescopic rod 504 and a supporting bracket 505.

A connecting plate 502 is fixed below the support plate 1, and the first electric telescopic rod 503 is connected between the connecting plate 502 and the second electric telescopic rod 504 through a movable shaft.

[0026] In specific implementation, most clamping claws usually use two clamping plates to clamp the scrapped automobile parts. Some parts are large in size, and the clamping force of the two clamping plates may not be enough. After clamping the scrapped automobile parts, the No. 1 electric telescopic rod 503 can be started, and the No. 1 electric telescopic rod 503 shrinks to pull the No. 2 electric telescopic rod 504 close to the scrapped automobile parts. At the same time, the No. 2 electric telescopic rod 504 extends, so that the No. 2 electric telescopic rod 504 drives the supporting frame 505 to reach the bottom end of the scrapped automobile parts, and the scrapped automobile parts are supported, thereby improving the clamping stability of the clamping claws.

[0027] Working principle: when using the clamping claw that can be stably clamped, first, start the cylinder 3 to push the telescopic plate 12 downward, so that the telescopic plate 12 pulls one end of the No. 2 connecting rod 11 to move downward, and the No. 2 connecting rod 11 squeezes the No. 1 connecting rod 6 through the rotating shaft 10, and one end of the No. 1 connecting rod 6 rotates on the No. 1 fixed plate 4, and then the cylinder 3 pulls the telescopic plate 12 upward, and the telescopic plate 12 drives one end of the No. 2 connecting rod 11 to move upward, and the No. 2 connecting rod 11 then drives one end of the No. 1 connecting rod 6 to rotate on the No. 1 fixed plate 4, and the No. 1 connecting rod 6 drives the outer splint 7 to approach the scrapped car parts, and the inner splint 9 is clamped on the outside of the scrapped car parts, and the bottom end of the scrapped car parts is supported by the supporting mechanism 5. When the worn inner splint 9 needs to be replaced, the inner splint 9 can be quickly removed from the outer splint 7 by the mounting mechanism 8 and replaced. The supporting mechanism 5 and the mounting mechanism 8 improve the stability and practicality of the clamping claw.
