[0119] Embodiment nine

[0120] The other of the inner wall surface of the accommodating cavity A and the second plug 91 has a protrusion 112 which abuts against the elastic sheet 913.

[0121] Embodiment nine is different from embodiment two in that the second plug 91 used is different.

[0122] As shown in Figures 30-36 , the bottom surface of the mounting groove 113 is an arc surface and is recessed towards the opening of the mounting groove 113, the protrusion 112 can be an outward protruding arc protrusion and can be arranged on the inner wall surface of the accommodating cavity A and the outer peripheral surface of the second plug 91 according to actual conditions, for example, as shown in Figures 30-31 , the protrusion 112 is arranged on the inner wall surface of the accommodating cavity A, the mounting groove 113 is two and is arranged on the upper and lower sides of the second plug 91, and the bottom surface of the mounting groove 113 on the upper side of the second plug 91 is a downward recessed arc surface, the bottom surface of the mounting groove 113 on the lower side of the second plug 91 is an upward recessed arc surface, the protrusion 112 is two and is arranged in the first recess 111 of the adjacent two splicing blocks respectively, so that when the second plug 91 is inserted into the accommodating cavity A, the protrusion 112 can extrude the elastic sheet 913 to move towards the bottom surface of the mounting groove 113 to fit the inner peripheral surface of the elastic sheet 913 with the bottom surface of the mounting groove 113, and the bottom surface of the mounting groove 113 and the outer peripheral surface of the protrusion 112 are in close contact with the elastic sheet 913, which improves the friction area of the second plug 91 and the splicing blocks, so that the second plug 91 fixes the two splicing blocks firmly and is not easy to slide out, or as shown in Figure 32 and Figure 34 , the number of protrusions 112 is two and is arranged on the upper and lower sides of the second plug 91, the number of mounting grooves 113 is two and is arranged on the bottom surface of the first recess 111 of the adjacent two splicing blocks respectively, so that when the second plug 91 is inserted into the accommodating cavity A, the protrusion 112 can extrude the elastic sheet 913 to move towards the bottom surface of the mounting groove 113 to fit the inner peripheral surface of the elastic sheet 913 with the bottom surface of the mounting groove 113, and the bottom surface of the mounting groove 113 and the outer peripheral surface of the protrusion 112 are in close contact with the elastic sheet 913, which improves the friction area of the second plug 91 and the splicing blocks, so that the second plug 91 fixes the two splicing blocks firmly and is not easy to slide out, or as shown in Figure 35 and Figure 36As shown, there are multiple protrusions 112, which are located on the outer circumferential surface of the pin 112. There are multiple mounting grooves 113, which are respectively located on the bottom surface of the first groove 111 of two adjacent splicing blocks. When the second pin 91 is inserted into the receiving cavity A, the protrusions 112 can squeeze the spring piece 913 towards the bottom surface of the mounting groove 113 to make the inner circumferential surface of the spring piece 913 fit against the bottom surface of the mounting groove 113. The bottom surface of the mounting groove 113 and the outer circumferential surface of the protrusion 112 are in close contact with the spring piece 913, which increases the friction area between the second pin 91 and the splicing block. Thus, the second pin 91 fixes the two splicing blocks firmly and makes them less likely to slip out.

[0123] Example 10

[0124] The spring 913 includes a rigid part 9131 and an elastic part 9132. The inner wall surface of the receiving cavity A and the other of the second pin 91 abut against the outer surface of the rigid part 9131. The elastic part 9132 is located at at least one end of the rigid part 9131 and abuts against the rigid part 9131.

[0125] The difference between Example 10 and Example 2 lies in the different arrangement of the spring 913.

[0126] like Figures 37-38 As shown, the rigid part 9131 is an arc-shaped plywood, bamboo, or steel sheet, and the elastic part 9132 can be a rubber sheet or elastic plate with elastic deformation. There can be two elastic parts 9132, which are respectively disposed at the left and right ends of the rigid part 9131. The two elastic parts 9132 can be glued to the left and right ends of the mounting groove 113 by adhesive. One end of the rigid part 9131 can abut against the elastic part 9132 on the left side. Then, the right end of the rigid part 9131 is squeezed so that the rigid part 9131 forms an arch shape and abuts against the elastic part 9132 on the right end. The middle part of the rigid part 9131 extends out of the mounting groove 113. When the mounting groove 113 is provided on the outer peripheral surface of the second pin 91, when the second pin 91 is inserted into the receiving cavity A, the inner wall surface of the receiving cavity A presses against the rigid part 9131. The rigid part 9131 presses against the elastic part 9132, causing the elastic part 9132 to compress and generate an elastic force. The elastic force of the elastic part 9132 reacts on the rigid part 9131, causing the rigid part 9131 to be in close contact with the inner peripheral surface of the receiving cavity A. Alternatively, when the mounting groove 113 is provided on the outer peripheral surface of the inner wall surface of the receiving cavity A, when the second pin 91 is inserted into the receiving cavity A, the outer peripheral surface of the second pin 91 presses against the rigid part 9131. The rigid part 9131 presses against the elastic part 9132, causing the elastic part 9132 to compress and generate an elastic force. The elastic force of the elastic part 9132 reacts on the rigid part 9131, causing the rigid part 9131 to be in close contact with the outer peripheral surface of the second pin 91.

[0127] In Embodiment Eleven, the elastic element 9133 is disposed between the rigid portion 9131 and the second pin 91, so that when the second pin 91 is inserted into the receiving cavity A, the elastic element 9133 has an elastic force that drives the rigid portion 9131 and the second pin 91 away from each other; or the elastic element 9133 is disposed between the rigid portion 9131 and the receiving cavity A, so that when the second pin 91 is inserted into the receiving cavity A, the elastic element 9133 has an elastic force that drives the rigid portion 9131 and the receiving cavity A away from each other.

[0128] The difference between Example 11 and Example 10 lies in the different arrangement of the spring piece 91.

[0129] like Figures 39-40 As shown, the rigid part 9131 is an arc-shaped steel sheet, the elastic part 913 is a rectangular rubber pad or a steel pad, and there can be two elastic parts 9132. The two elastic parts 9132 are respectively provided at the left and right ends of the rigid part 9131. The two elastic parts 9132 can be glued to the left and right ends of the mounting groove 113. The left and right ends of the rigid part 9131 are respectively provided with baffles 9135. The rigid part 9131 abuts against the two elastic parts 913 through the two baffles 9135. The rigid part 9131 is arched and abuts against the elastic part 9132 at the right end. A mounting sleeve 9134 is fixed to the side of the rigid part 9131 facing the mounting groove 113. The side of the mounting groove 113 facing the rigid part 9131 is provided with a mounting hole 934. The mounting sleeve 9134 and the mounting hole 934 are spaced apart in the vertical direction. The two ends of the elastic element 9133 are respectively inserted into the mounting hole 934 and the mounting sleeve 9134. When the mounting groove 113 is provided on the outer peripheral surface of the second pin 91, when the second pin 91 is inserted into the receiving cavity A, the inner wall of the receiving cavity A is pressed against the rigid part 9131. The rigid part 9131 presses against the elastic part 9132 to compress the elastic part 9132 to generate elastic force. At the same time, the rigid part 9131 presses against the elastic element 9133 to compress the elastic part 9132 to generate elastic force. The elastic force of the elastic element 9133 and the elastic part 9132 reacts to the rigid part 9131 so that the rigid part 9131 is in close contact with the inner peripheral surface of the receiving cavity A.

[0130] Alternatively, when the mounting groove 113 is located on the outer peripheral surface of the inner wall of the receiving cavity A, and the second pin 91 is inserted into the receiving cavity A, the outer peripheral surface of the second pin 91 presses the rigid part 9131, and the rigid part 9131 presses the elastic part 9132 to compress the elastic part 9132 to generate an elastic force. At the same time, the rigid part 9131 presses the elastic member 9133 to compress the elastic part 9132 to generate an elastic force. The elastic forces of the elastic member 9133 and the elastic part 9132 react on the rigid part 9131 to make the rigid part 9131 in close contact with the outer peripheral surface of the second pin 91.
