In this embodiment, the number of the locking components 4 is eight, and two of the locking components 4 are respectively provided at the front end, rear end, left side and right side of the base frame 1. The fitting surface of the inner side of the limiting plate 3 is adapted to the outer peripheral shape of the bathtub. The number of the limiting plates 3 is two. During operation, the inner cylinder is placed on the placement seat 2 so that the inner wall of the inner cylinder fits the placement seat 2, and then the two limiting plates 3 are moved closer to the inner cylinder until the inner side surfaces of the front and rear ends of the two limiting plates 3 respectively abut against the left and right sides of the two positioning protrusions 211, and then the two limiting plates 3 are locked and fixed by the eight locking components 4. At this time, the inner cylinder is limited and fixed by the lower half of the limiting plates 3, and then the outer cylinder is covered on the inner cylinder so that the outer periphery of the outer cylinder fits the two limiting plates 3. Specifically, the upper half of the two limiting plates 3 limit and fix the outer cylinder, and then the glue injection holes reserved in the outer cylinder are used to inject glue into the outer cylinder and the inner cylinder. Pour the mixed resin into the gap between the cylinders, and after standing for thirty minutes, the mixed resin is cured, the inner cylinder and the outer cylinder are connected into an integrated structure, and then the locking assembly 4 is loosened to take out the two limit plates 3, and finally the integrated bathtub is taken out for subsequent correction and polishing; the present application uses the base frame 1, the placement seat 2, the positioning protrusion 211, the limit plate 3 and the locking assembly 4, so that the inner side surfaces of the front and rear ends of the limit plate 3 can be against the two sides of the two positioning protrusions 211, which can not only quickly locate the limit, but also ensure that the limit plate 3 fits without deviation, and eight locking assemblies 4 are used to lock and fix the four directions of the front, back, left and right of the bathtub, which can not only prevent the misalignment when the inner cylinder and the outer cylinder are docked, but also avoid the deformation of the bathtub during the curing process of the mixed resin, and there is no need to perform large-scale polishing in the future, which saves time and effort, and is conducive to improving the product production quality and production efficiency. Preferably, the part where the inner cylinder and the outer cylinder are docked is polished at 45°, so as to facilitate the mixed resin to enter and produce a better bonding effect.
