Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 3, a projector convenient to adjust for english teaching comprises a projector body 1, an adjusting screw, a slide block 3 and a slide rail 4; the adjusting screw rods are vertically arranged, the sliding blocks 3 are installed at the bottom ends of the adjusting screw rods, and the sliding rails 3 are transversely installed at the top of the projector body 1.
As shown in fig. 1 and 6, the adjusting screw includes a first screw 21, a second screw 22, and a sleeve 23; a limiting plate 24 is arranged in the middle of the sleeve 23, the upper portion of the sleeve 23 is in threaded connection with the first screw 21, and the lower portion of the sleeve 23 is in threaded connection with the second screw 22. The first screw 21 is a coarse thread, and the second screw 22 is a fine thread. The top end of the first screw 21 is provided with a mounting seat. By arranging the first screw 21 and the second screw 22 with different pitches, the coarse adjustment and the fine adjustment of the height of the projector can be realized, so that the height adjustment is quicker and more accurate.
