Board structure having articulated joints and splice object having the same

A splice object having articulated joints, comprising a plurality of first boards and a plurality of second boards;

• wherein at least one of the plurality of first boards has a first adjacent edge, a first holding slot, and a first articulated arm, the first articulated arm protrudes outward from a part of the first adjacent edge, and the first holding slot is adjacent to the first articulated arm and is recessed inward from the first adjacent edge;
• wherein the first articulated arm has a first longitudinal part, and a first transverse part protrudes from one lateral side of an end portion of the first longitudinal part;
• wherein at least one of the plurality of second boards has a second adjacent edge, a second holding slot, and a second articulated arm, the second articulated arm protrudes outward from a part of the second adjacent edge, and the second holding slot is adjacent to the second articulated arm and is recessed inward from the second adjacent edge;
• wherein the second articulated arm has a second longitudinal part, and a second transverse part protrudes from one lateral side of an end portion of the second longitudinal part;
• wherein the first adjacent edge faces the second adjacent edge to define an articulated seam, the first articulated arm is accommodated in the second holding slot, and the second articulated arm is accommodated in the first holding slot;
• wherein the at least one of the plurality of first boards and the at least one of the plurality of second boards are able to be positioned at various angles relative to each other along the articulated seam, the first transverse part abuts against an inner wall surface of the second holding slot, and the second transverse part abuts against an inner wall surface of the first holding slot.

A board structure having articulated joints, comprising:

• a first board having a first adjacent edge and a first holding slot, wherein the first holding slot is recessed inward from the first adjacent edge;
• and
• a second board having a second adjacent edge and an articulated arm, wherein the articulated arm protrudes outward from a part of the second adjacent edge, the articulated arm has a longitudinal part, and a transverse part protrudes from one lateral side of an end portion of the longitudinal part;
• wherein the first adjacent edge faces the second adjacent edge to define an articulated seam, and the articulated arm is accommodated in the first holding slot;
• wherein the first board and the second board are able to be positioned at various angles relative to each other along the articulated seam, and the transverse part abuts against an inner wall surface of the first holding slot.
