Therefore, welding is the most critical manufacturing process of bucket, and the welding quality directly affects the structural strength and service life of the bucket.

[0003] A Chinese patent discloses an excavator bucket support device (authorization announcement number CN210827655U). This patented technology facilitates the movement of the originally large and heavy bucket through a rolling device installed at the bottom of the base. Considering its weight, a suitable guide rail is laid at the bottom of the rolling device to minimize friction and increase the support weight as much as possible. A multi-layered shock-absorbing structure is designed to ensure maximum support and protection for the bucket.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: since the existing excavator bucket support structure cannot fix the bucket during use, the bucket is prone to uneven welding, which in turn affects the strength of the bucket structure and the length of its service life.
