[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 5, the present utility model provides a surveying and positioning bracket, which includes a support plate 1. Hanging ears 2 are circumferentially and evenly distributed along the axis at the bottom of the support plate 1. A telescopic assembly 3 is rotatably arranged at the hanging ears 2. After the telescopic assembly 3 is expanded, it is locked to the hanging ears 2 through a locking bolt 4. After the telescopic assembly is retracted, the telescopic assembly can be placed flat under the support plate. When the slider slides out, the three telescopic assemblies and the pointed supports will not touch each other, occupying a small area. When it is expanded, as long as a pointed support 5 is provided at the bottom of the telescopic assembly 3, the pointed support 5 is screwed to the sliding rod, and a hexagonal groove is provided at the top end of the pointed support 5. The hexagonal groove can be screwed by a hexagonal wrench to adjust the position of the pointed support. Horizontally arranged at the upper end of the hanging ear 2 is a slider 6 intersecting with the axis of the support plate 1. A sliding groove for the slider 6 to slide is provided at the bottom of the support plate 1. A locking bolt 7 for locking the slider 6 to the sliding groove is screwed on the slider 6. After the slider slides out to the end, it is locked by the locking bolt, so that the three retracted telescopic assemblies and the pointed supports will not touch each other. After the telescopic assembly is expanded, it is locked to the hanging ear through the locking bolt. After the slider slides in to the end, it is locked by the locking bolt.

[0018] Refer to Figure 4 , Figure 5 , the telescopic assembly 3 includes multiple sections of pipe fittings that can be telescopically extended in sequence. A sliding rod is telescopically arranged inside the lowermost pipe fitting. The pipe fitting includes a sleeve 3.1, a ferrule 3.2, and a buckle 3.3. A ferrule 3.2 is coaxially arranged at the lower end of the sleeve 3.1, and a buckle 3.3 is rotatably arranged at the ferrule 3.2. The upper end face of the movable groove is lower than the lower end face of the sleeve. The buckle can catch the sliding rod or the next sleeve. The sleeve and the sliding rod can be extended to expand, and the sleeve and the sliding rod can be retracted to be folded up.

[0019] The ferrule 3.2 and the buckle 3.3 are plastic parts. The plastic parts have elasticity. The buckle is composed of a cylindrical connecting wrench. A protrusion is provided on the side wall of the cylinder. The ferrule 3,2 is connected to the sleeve 3.1 as a plastic insert.

[0020] The ferrule 3.2 includes a cylinder 3.2.1 connected to the lower end of the sleeve 3.1. An inner ring 3.2.2 is provided on the inner side of the lower end of the cylinder 3.2.1. An activity groove 3.2.3 for the buckle 3.3 to rotate is provided on the side wall of the cylinder 3.2.1. The cylinder is connected to the sleeve. The inner wall of the inner ring and the inner wall of the connected sleeve can both accommodate the sliding rod or the next sleeve to slide. By turning the buckle, the sliding rod or the next sleeve can be caught.

[0021] A limit block 8 for limiting the locking bolt 7 is provided at the lower end of the support plate 1. The provision of the limit block can prevent the slider and the telescopic assembly from sliding out of the sliding groove.

[0022] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
