[0020] During use, through the interaction of the set middle cross piece 1, left mortise and tenon connection block 4, right mortise and tenon connection block 7, left supporting column 2, left mortise and tenon connection groove 3, left positioning card slot 8, right supporting column 5, right mortise and tenon connection groove 6, right positioning card slot 9, positioning card block 10, through hole 11 and pointed wood screw 12, the wooden furniture support legs can be easily assembled through the mortise and tenon structure during use, and the operation is simple and easy to disassemble and assemble, so that users can better operate and thus achieve better practicality.

[0021] Working principle: When working, first insert the left mortise and tenon connection block 4 on the left side of the middle crossbar 1 from top to bottom into the left mortise and tenon connection groove 3 opened on the outside of the left support column 2. Due to the tapered structural characteristics of the left mortise and tenon connection groove 3, the left mortise and tenon connection block 4 can be firmly inserted into it. After the left mortise and tenon connection block 4 is fully inserted into the left mortise and tenon connection groove 3, take one of the positioning blocks 10 and insert the positioning block 10 into the left positioning slot 8. Then, turn the pointed wood screw 12 inside the positioning block 10. As the pointed wood screw 12 drills into The left positioning slot 8 is inserted into the positioning block 10, and the positioning block 10 also moves into the left positioning slot 8. Since the top of the positioning block 10 is a sloped structure, the positioning block 10 will squeeze the left mortise and tenon connection block 4 downward under the action of the upper inclined wedge surface during the movement, and squeeze the left mortise and tenon connection block 4 into the left mortise and tenon connection groove 3. Then, the right mortise and tenon connection block 7 on the right side of the middle cross piece 1 is inserted from top to bottom into the right mortise and tenon connection groove 6 opened on the outside of the right support column 5. Due to the tapered structural characteristics of the right mortise and tenon connection groove 6, the right mortise and tenon connection block 7 can be tightly fastened. After the right mortise and tenon connection block 7 is fully inserted into the right mortise and tenon connection groove 6, take another positioning block 10 and insert the positioning block 10 into the right positioning groove 9. Then, turn the pointed wood screw 12 inside the positioning block 10. As the pointed wood screw 12 drills into the right positioning groove 9, the positioning block 10 also moves into the left positioning groove 9. Since the top of the positioning block 10 is a sloped structure, the positioning block 10 will squeeze the right mortise and tenon connection block downward under the action of the upper inclined wedge surface during the movement. Block 7, squeeze and position the right mortise and tenon connecting block 7 inside the right mortise and tenon connecting groove 5, and complete the assembly between the left support column 2, the middle cross piece 1 and the right support column 5. When disassembly is required, unscrew the pointed wood screw 12, take out the positioning card block 10, and then respectively pull out the left support column 2 and the right support column 5 from both ends of the middle cross piece 1. In this way, the support legs of wooden furniture can be easily assembled through the mortise and tenon structure during use, and the operation is simple and easy to disassemble and assemble, so that users can better operate it, thereby achieving better practicality.
