By adjusting the length of the thin rod extending from the thick rod, the height of the song ordering machine can be adjusted, thereby meeting the height requirements of the operator and facilitating the operator's use.

[0017] 1. The utility model allows an operator to pull the handle outward, during which the cylindrical rod, the push plate and the insert block move outward, causing the push plate to compress the spring, making the spring elastic, and causing the insert block to retract into the inner wall of the turntable and no longer engage with the groove on the connecting frame. Without the connection frame being limited by the insert block, the operator can rotate the connecting frame, thereby facilitating adjustment of the direction of the song-ordering machine screen and improving convenience in ordering songs.

[0018] 2. The utility model has the following steps: the operator presses the pressing blocks on both sides of the thick rod at the same time to retract the pressing blocks into the round holes on the thick rod, and then pulls the thin rod out of the thick rod to a suitable length. When the pressing blocks encounter the corresponding round holes, the pressing blocks pass through the corresponding round holes on the outer wall of the thick rod under the push of spring 2, thereby keeping the lengths of the thin rod and the thick rod fixed. By adjusting the height of the song request machine, the height requirements of the operator can be met for easy use by the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 and Figure 2As shown, a song ordering machine that is convenient for adjusting the screen angle includes a song ordering screen 1 and an adjustment component 4, a connecting frame 2 is provided at the lower end of the song ordering screen 1, and a turntable 3 is provided on the outer side of the lower end of the connecting frame 2, the adjustment component 4 runs through the inner wall of the turntable 3, and the adjustment component 4 includes a cylindrical rod 401, a handle 402, a spring 403, a push plate 404, an insert 405 and a groove 406, a handle 402 is provided at the right end of the cylindrical rod 401, and a spring 403 is provided on the outer side of the cylindrical rod 401, a push plate 404 is provided at the left end of the spring 403, and the left side of the push plate 404 An insert block 405 is provided at the end, and a groove 406 is provided on the outer side of the insert block 405. The operator pulls the handle 402 outward, and during the pulling process, the cylindrical rod 401, the push plate 404 and the insert block 405 move outward, so that the push plate 404 compresses the spring 403 so that the spring 403 has elasticity, and the insert block 405 is retracted into the inner wall of the turntable 3 and no longer engages with the groove 406 on the connecting frame 2. Without the limitation of the insert block 405 on the connecting frame 2, the operator can rotate the connecting frame 2, thereby facilitating the adjustment of the screen direction of the song ordering machine and improving the convenience of ordering songs.

[0026] like Figure 3 and Figure 4 As shown, a thin rod 5 is provided at the lower end of the turntable 3, and a thick rod 6 is provided on the outer side of the thin rod 5, and lifting components 7 are provided on both the left and right sides of the inside of the thin rod 5, and the lifting component 7 includes an inner groove 701 and a second spring 702, and the inner groove 701 is provided with a second spring 702, and the lifting component 7 also includes a pressing block 703 and a circular hole 704, and the second spring 702 is provided on the side away from the central axis of the thin rod 5. The outer side of the pressing block 703 is provided with a circular hole 704, and the operator Press the pressing blocks 703 on both sides of the thick rod 6 to retract the pressing blocks 703 into the circular holes 704 opened on the thick rod 6, and then pull the thin rod 5 out of the thick rod 6 to a suitable length. When the pressing blocks 703 encounter the corresponding circular holes 704, under the push of the spring 2 702, the pressing blocks 703 pass through the corresponding circular holes 704 opened on the outer wall of the thick rod 6, so that the lengths of the thin rod 5 and the thick rod 6 remain fixed, and the height of the song request machine can be adjusted to meet the height requirements of the operator for the convenience of the operator.

[0027] like Figure 3 and Figure 5As shown, a mounting seat 8 is provided at the lower end of the thick rod 6, and a base 9 is provided at the lower end of the mounting seat 8. A groove 2 10 is provided above the inner wall of the mounting seat 8, and a mounting assembly 11 is provided inside the groove 2 10. The mounting assembly 11 includes a hexagonal groove screw head 1101 and a screw 1102, and the lower end of the hexagonal groove screw head 1101 is provided with a screw 1102. The mounting assembly 11 also includes a threaded hole 1103 and a threaded hole 2 1104. The outer side of the screw 1102 is provided with a threaded hole 1103, and the lower end of the threaded hole 1103 is provided with a threaded hole 2 1104. The operator aligns the screw 1102, pushes it into the hexagonal groove screw head 1101 with a hexagonal screwdriver, and then rotates the screw 1102 to turn it into the threaded hole 1103 and the threaded hole 2 1104 until the hexagonal groove screw head 1101 is pressed against the inner wall of the groove 2 10, thereby facilitating the quick installation of the song request machine on the base 9 of the karaoke room.

[0028] Working principle: When using the song-ordering machine that is easy to adjust the screen angle, first, the operator aligns the screw 1102, pushes the hexagonal screwdriver into the hexagonal screw head 1101, and then rotates the screw 1102 to threaded hole 1 103 and threaded hole 2 1104 until the hexagonal screw head 1101 presses against the inner wall of groove 2 10, and quickly installs the song-ordering machine on the base 9 of the karaoke room. Then the operator presses the pressing blocks 703 on both sides of the thick rod 6 at the same time, so that the pressing blocks 703 are retracted into the circular holes 704 opened on the thick rod 6, and then the thin rod 5 is pulled out of the thick rod 6 to a suitable length. When the pressing block 703 encounters the corresponding circular hole 704, the pressing block 703 passes through the corresponding circular hole 704 opened on the outer wall of the thick rod 6 under the push of the spring 2 702, so that the length of the thin rod 5 and the thick rod 6 remains fixed. The operator can adjust the extension length of the thin rod 5 from the thick rod 6 according to his own height requirements, and then adjust the height of the song-ordering machine. Then the operator pulls the handle 402 outward. During the pulling process, the cylindrical rod 401, the push plate 404 and the plug block 405 move outward, so that the push plate 404 compresses the spring 403, so that the spring 403 has elasticity, and the plug block 405 retracts into the inner wall of the turntable 3 and no longer engages with the groove 406 on the connecting frame 2. Without the restriction of the plug block 405 on the connecting frame 2, the operator can rotate the connecting frame 2 to facilitate the adjustment of the screen direction of the song-ordering machine. When the screen position is adjusted, the handle 402 is released. At this time, the spring 403 rebounds in the opposite direction to push the push plate 404 to move inward, so that the plug block 405 is inserted into the corresponding groove 406, and the song-ordering screen 1 is kept fixed.
