[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-3 shown, a frame positioning fixture includes a fixture body 1. The fixture body 1 includes two side plates 2. At least one hanging hole 21 is provided on each of the two side plates 2. At least one positioning rod 3 is provided between the two side plates 2. A plurality of protruding portions 31 are arranged along the axial direction of each positioning rod 3. A positioning groove 32 is formed between two adjacent protruding portions 31. The positioning groove 32 is arranged higher than the positioning rod 3. The positioning rod 3 protrudes from two side surfaces opposite to the protruding portions 31 in the radial direction. The cross-section of the positioning rod 3 is circular or elliptical. The protruding portion 31 is configured as a sheet body, and the positioning rod 3 is configured as a cylinder. An extension piece 22 is provided at the upper position of the inner side surface of the side plate 2 above the hanging hole 21. A plurality of connecting rods 4 are connected between the two side plates 2. The end of at least one connecting rod 4 extends out of the side plate 2 to form an extension portion 41.

[0022] The present utility model also provides a frame connecting member 5. The connecting member 5 includes an inserting portion 51 connected to the above-mentioned positioning rod 3. The inserting portion 51 includes two arc-shaped pieces 52. A slot 53 adapted to the positioning rod 3 is formed between the two arc-shaped pieces 52. A limiting groove 54 adapted to the positioning groove 32 is provided in the slot 53.

[0023] By adopting the above technical solutions, in the present utility model, the hanging hole 21 is provided for hanging the fixture body 1 on the fixture hanging member. Among them, the extension piece 22 is provided for connecting with the fixture hanging member. Compared with directly connecting the side plate 2 with the fixture hanging member, the area of the hanging connection is increased, and the connection is more stable. By providing the connecting rod 4, the connection stability between the two side plates 2 is enhanced, so that the fixture body 1 has better structural strength and better support for the frame positioned and installed on the fixture body 1. The most important innovation point of the present utility model lies in the design of the structure of the positioning rod 3. Among them, the positioning rod 3 is specifically in a cylindrical shape. The protruding portion 31 is provided on its structure. The positioning groove 32 between two adjacent protruding portions 31 is used for positioning and connecting the frame connecting member 5. By inserting the inserting portion 51 on the positioning rod 3 and matching the limiting groove 54 with the position of the protruding portion 31 below the positioning groove 32, good positioning and installation of the frame connecting member 5 can be achieved, and the frame will not swing when installed on the positioning fixture, and the connection stability is better. Among them, the frame connecting member 5 can be directly or indirectly connected to the frame.
