[0036] As a technical optimization solution of the present invention, in order to adjust the spacing between the L-shaped frames 1801, thread grooves are provided inside the No. 1 thread seat 1905 and the No. 2 thread seat 1906, and the thread grooves inside the No. 1 thread seat 1905 and the No. 2 thread seat 1906 have opposite rotation directions.

[0037] When the present invention is in use, the hand wheel 6 is rotated, and the driving column 5 rotates accordingly. The driving column 5 drives the active gear 7 to engage with the driven gear 8, and the driven gear 8 drives the linkage shaft 9 to rotate.

[0040] When the casting mold is large, turn the handle 1904 clockwise, and the threaded rod 1902 rotates accordingly and meshes with the No. 1 thread seat 1905 and the No. 2 thread seat 1906, and the No. 1 thread seat 1905 and the No. 2 thread seat 1906 move relative to each other, and the No. 1 thread seat 1905 and the No. 2 thread seat 1906 drive different L-shaped frames 1801 to move outward, and the spacing between different L-shaped frames 1801 increases, so that a larger casting mold can be supported and resisted. When the casting mold is small, turn the handle 1904 clockwise, and the threaded rod 1902 rotates accordingly and meshes with the No. 1 thread seat 1905 and the No. 2 thread seat 1906. By turning the handle 1904, the threaded rod 1902 engages with the No. 1 threaded seat 1905 and the No. 2 threaded seat 1906, and the No. 1 threaded seat 1905 and the No. 2 threaded seat 1906 move toward each other, and the No. 1 threaded seat 1905 and the No. 2 threaded seat 1906 drive different L-shaped frames 1801 to move inward, and the distance between different L-shaped frames 1801 is reduced, so that smaller casting molds can be supported and resisted, and casting molds of different sizes can be supported and resisted, which is more practical.
