[0034] Specifically, two fixing clips 4 are provided, and the two fixing clips 4 are spaced apart along the width direction of the base 3. In this embodiment, the fixing clip 4 adopts a toggle clip. When the first splicing piece 1 is placed on the upper surface of the front end of the base 3, the operator toggles the fixing clip 4, and the fixing clip 4 cooperates with the base 3 to clamp the first splicing piece 1 accordingly, thereby fixing the first splicing piece 1.

[0035] Furthermore, a first positioning block 31 and a second positioning block 32 are fixed to the front end of the base 3. Two first positioning blocks 31 are provided, and the two first positioning blocks 31 are symmetrically arranged on both sides of the upper surface of the base 3 to abut and position the left and right sides of the first splicing piece 1.
