[0019] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following will further illustrate the utility model by combining with specific drawings.

[0020] REFERENCE Figures 1-4As shown, a bamboo structure connecting fastener, comprising a connecting piece 1 and a transverse positioning piece 2, the connecting piece 1 can be attached to the outer wall of two mutually connected bamboo poles, and the two connecting pieces 1 are connected by a damping rotating shaft 5 to realize synchronous adjustment according to the installation angle between the two bamboo poles, and the installation angle between the two bamboo poles is pre-positioned, so that when the two bamboo poles are connected at a certain angle, the angle deviation caused by the installation is avoided, and the connection accuracy between the bamboo poles is affected. After adjusting the included angle between the two connecting pieces 1 according to the set connection angle between the two bamboo poles, the random rotation between the two connecting pieces 1 can be avoided under the action of the damping rotating shaft 5. After the angle between the two bamboo poles is preliminarily positioned by the two connecting pieces 1, the transverse positioning piece 2 penetrates the two connecting pieces 1 and the two bamboo poles, so that the two mutually connected bamboo poles and the transverse positioning piece 2 together form a stable triangular connection structure, thereby making the connection of the two connected bamboo poles more stable.

[0021] Specifically, the transverse positioning piece 2 comprises two mutually sleeved and threadedly connected adjusting rod bodies 21, the ends of the two adjusting rod bodies 21 away from each other are provided with fixed portions 22, and threadedly connected with abutting rings 23. After the two connected bamboo poles are preliminarily positioned by the two connecting pieces 1, a drill rod or the like is used to drill holes in the two bamboo poles, so that the hole axes of the two bamboo poles coincide, and then one end of each of the two adjusting rod bodies 21 is inserted through the two connecting pieces 1 and the two bamboo poles, and the opposite ends of the two adjusting rod bodies 21 are threadedly connected. Then, the abutting rings 23 are rotated to abut against the bamboo poles, and the fixed portions 22 at the other ends of the adjusting rod bodies 21 abut against the connecting pieces 1, so as to connect the transverse connecting portion between the two connecting pieces 1 and form a stable triangular structure, thereby avoiding the angle deviation between the connected two bamboo poles and improving the connection stability. Meanwhile, the two bamboo poles in a non-vertical state can also be connected.

[0022] Referring to Figure 2 Further, as shown, in order to make the preliminary connection of the connecting piece 1 and the bamboo pole more stable, the connecting piece 1 is slidably connected with a clamping seat 31 having an open end opposite to the opening of the connecting piece 1 through a slide rod 3, the clamping seat 31 is threadedly connected with a locking piece 32, and the connecting piece 1 is provided with a locking hole 33 for fixing the locking piece 32. During installation, first, the bamboo pole is placed in the opening of the connecting piece 1, then the slide rod 3 drives the clamping seat 31 to move towards the connecting piece 1 to clamp the bamboo pole, and then the locking piece 32 is rotated to be connected to the locking hole 33, so as to clamp and fix the bamboo pole by the cooperation of the clamping seat 31 and the connecting piece 1. Thus, when the bamboo pole is placed in the opening end of the connecting piece 1, it will not move randomly, thereby ensuring the connection stability between the two bamboo poles.

[0023] The opening sections of the clamping seat 31 and the connecting piece 1 are all in the shape of V, which can adapt to clamping bamboo poles with different diameters, and the adaptation range is wider; meanwhile, the inner walls of the opening sections of the clamping seat 31 and the connecting piece 1 are all provided with buffer pads 4 made of elastic materials such as rubber or silica gel, which can increase the friction between the connecting piece 1 and the bamboo pole, improve the stability, and protect the bamboo pole through the buffer pads 4, so as to avoid the direct contact between the bamboo pole and the connecting piece 1 and the damage of the outer wall of the bamboo pole.

[0024] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and all the changes and improvements fall within the scope of the utility model claimed.
