The connecting rods 1 on both sides drive the disc 3 to move. The disc 3 on one side away from the connecting rod 1 is fixedly connected to an insert block 4. The discs 3 on both sides drive the insert block 4 to move. The insert blocks 4 on both sides are inserted into the excavator bucket. The connecting rod 1 on one side away from the disc 3 is fixedly connected to a shell 6. An adjusting device 5 is provided inside the shell 6. The adjusting device 5 is provided with two groups. The adjusting device 5 includes: a pull rod 51, which passes through the shell 6 and is movably connected to the shell 6. The operator presses the pull rods 51 on both sides in turn, and the pull rod 51 moves in the shell 6. The block 52 is fixedly connected to the end of the pull rod 51. The pull rod 51 drives the block 52 to move. The material of the first spring 53 is carbon spring steel. The elastic coefficient of the first spring 53 is selected according to actual needs and can meet the work. The first spring 53 is fixedly connected to the inner wall of the shell 6 and the outer wall of the block 52 at both ends. The block 52 drives the first spring 53 to stretch. The block 52 is inserted into the slot 54. The material of the second spring 56 is Carbon spring steel, the elastic coefficient of the second spring 56 is selected according to actual needs and can meet the work. The second spring 56 is fixedly connected to the inner wall of the shell 6, so that the plug 55 leaves the socket 57, and the plug 55 compresses the second spring 56. The socket 57 is opened on the inner wall of the connecting column 7. The plug 55 is fixedly connected to the end of the second spring 56 and is plugged into the inner wall of the socket 57. The card slot 54 is opened on the inner wall of the plug 55. The guide assembly 58 is set inside the shell 6. After the movement is completed, the staff releases the pull rods 51 on both sides in turn. At this time, the first spring 53 rebounds, and the The block 52 is rebounded to its initial position by the elastic force and leaves the card slot 54. The second spring 56 rebounds and inserts the plug post 55 into the corresponding socket 57 by the elastic force, completing the adjustment of the connecting rods 1 on both sides. The block 52 is inserted into the card slot 54 under the drive of the pull rod 51, thereby moving the plug post 55 and compressing the second spring 56 to adjust the connecting rod 1. After the adjustment is completed, the staff releases the pull rod 51, thereby inserting the plug post 55 into the corresponding socket 57, and quickly adjusting the connecting rod 1. The plug post 55 is guided by the guide assembly 58 to prevent the second spring 56 from bending.

[0025] In the specific implementation process, it is worth noting that the material of the first spring 53 is carbon spring steel, and the elastic coefficient of the first spring 53 is selected according to actual needs, and it can meet the work. The material of the second spring 56 is carbon spring steel, and the elastic coefficient of the second spring 56 is selected according to actual needs, and it can meet the work. When it is necessary to adjust the connecting rods 1 on both sides, the staff presses the pull rods 51 on both sides in turn, and the pull rods 51 move in the housing 6. The pull rods 51 drive the block 52 to move, and the block 52 drives the first spring 53 to stretch, and the block 52 is inserted into the slot 54, so that the plug 55 leaves the socket 5 7, the plug column 55 compresses the second spring 56. After completion, the staff moves the connecting rod 1, and the connecting rod 1 moves on the connecting column 7. The connecting rods 1 on both sides drive the disc 3 to move, and the disc 3 on both sides drive the plug block 4 to move. The plug blocks 4 on both sides are inserted into the excavator bucket. After the movement is completed, the staff releases the pull rods 51 on both sides in turn. At this time, the first spring 53 rebounds and uses the elastic force to bounce the block 52 back to the initial position and leave the card slot 54. The second spring 56 rebounds and uses the elastic force to insert the plug column 55 into the corresponding socket 57, completing the adjustment of the connecting rods 1 on both sides, and realizing rapid adjustment of the connecting rod 1;

[0026] Furthermore, the guide assembly 58 includes: a connecting block 581, which is fixedly connected to the side wall of the plug post 55.

A sliding post 582 is fixedly connected to the inner wall of the shell 6 and is slidably engaged with the inner wall of the connecting block 581. The connecting block 581 moves on the sliding post 582. A cross block 583 is fixedly connected to the end of the sliding post 582 away from the shell 6. The cross block 583 limits the sliding post 582 to prevent the connecting block 581 from moving out of the sliding post 582 and fits the outer wall of the connecting block 581. The connecting block 581 slides on the sliding post 582 under the drive of the plug post 55 to guide the plug post 55 and prevent the second spring 56 from bending.

[0027] In the specific implementation process, it is worth noting that when the plug post 55 moves, the plug post 55 drives the connecting block 581 to move, and the connecting block 581 moves on the sliding post 582.
