A bucket 2 is welded to the rear end of the connecting seat 3.

[0022] The two levers 7 are both L-shaped, and the front ends of the two levers 7 extend out of the slide slot 8. This design is conducive to the use of the present device. The bracket 6 is U-shaped, and the bracket 6 is sleeved on the two levers 7. The bracket 6 can limit the two levers 7. A positioning bracket 15 is fixedly installed on the crossbeam 11.

The rear ends of the two carriers 1 are fixedly installed with connecting frames 4, which facilitate the connection of the carrier 1 with the skid loader.

[0023] Working principle: When installation is required, the bracket 6 can be pulled downward first, and the bracket 6 drives the bottom plate 5 to descend, so that the bracket 6 is separated from the two levers 7. At this time, the two levers 7 lose their limits, and the two levers 7 are pulled toward the side away from each other. The two levers 7 drive the two push rods 9 and the slider 12 to slide toward the side away from each other. The two sliders 12 drive the two T-shaped rods 14 to slide toward the side away from each other into the storage groove 10, and then align the positioning groove 16 on the connecting seat 3 with the positioning bracket 15 for clamping, release the lever 7, and at this time the two first springs 13 drive the slider 12 to return, so that the two T-shaped rods 14 are clamped into the corresponding T-shaped grooves 17, and finally release the bracket 6, and the second spring 20 drives the slide plate 1 9 returns to its original position, so that the base plate 5 drives the bracket 6 to rise, and the bracket 6 is sleeved on each chain lever 7, and the installation of the bucket 2 can be completed. The bucket 2 can also be quickly disassembled using the above principle. This novel quick-change device for skid loader accessories is easy to use. The bucket 2 and the carrier 1 can be quickly disassembled and assembled through the above components, thereby further improving the assembly efficiency and facilitating subsequent disassembly and replacement. At the same time, it can avoid the use of bolt connections. After long-term use, the bolts are rusted, which easily leads to the problem of difficulty in disassembly. It should be noted that the elastic force of the spring is selected by technical personnel in this field through existing technology, so that the elastic force of the spring can ensure the limiting and fixing effect of the bracket 6 and the T-bar 14.
