Detailed Description

The foregoing and other features, aspects and utilities of the present invention will be apparent from the following detailed description of the embodiments, which is to be read in connection with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Therefore, the directional terminology used is for the purpose of describing, but not limiting, the invention, and moreover, like reference numerals designate like elements throughout the embodiments.

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is a top view of the present invention, and fig. 2 is a side view of the present invention. With reference to fig. 1 and 2, a positioning connection tooth block comprises a connection seat 1 and a base 2 from top to bottom. The shape of the connecting seat 1 is square or fan-shaped. The base 2 is square or fan-shaped. In this embodiment, the shape of the connecting seat 1 and the shape of the base 2 are both square. Both sides of the connecting seat 1 comprise inclined planes 3 in transitional connection with the base 2. The inclined surface 3 is provided with engaging teeth 4. The teeth 4 are arranged equidistantly on the ramp 3. The connecting seat 1 and the base 2 are integrally formed. The connecting seat 1 is provided with a through hole 5. The circumferential surface of the through-hole 5 is not provided with the engaging teeth 4. The through hole 5 extends downward along the axis of the through hole and penetrates through the base 2. The L-shaped right angle block 6 comprises a first plate 61 and a second plate 62 perpendicular to each other. The first plate 61 is provided with a waist-shaped hole, and the second plate 62 is provided with a round hole. The engagement teeth 4 pass through the kidney-shaped holes of the first plate 61. And the bolt passes through the through hole 5 and is screwed by a nut, so that the positioning connecting tooth block and the L-shaped right-angle seat 6 are fastened.
