[0022] Please see Figure 1-4 This utility model provides a technical solution: a protective device for a music teaching metronome, including a metronome body 1. A groove 11 is formed on the outside of the metronome body 1. Two mounting plates 12, L-shaped, are fixedly installed on the side of the metronome body 1 away from the groove 11. A protective shell 13 is movably connected inside the groove 11. The protective shell 13 is open on the side near the groove 11. Two grooves 23 are formed on both sides of the inner wall of the groove 11. A positioning groove 22 is formed on the inner wall of each groove 23. Four square rods 15 are arranged on the side of the protective shell 13 near the inner wall of the groove 11. The four square rods 15 are movably connected inside the four grooves 23, and each square rod 15 is fixedly connected to an external part. Card Block 16, Card Block 16 is movably connected inside the groove 23, and an opening mechanism is provided between every two square rods 15 on the same side.

[0023] Each opening mechanism includes a long slot 19 and two through slots 14. The long slot 19 is opened inside the protective shell 13. The two through slots 14 are respectively opened above and below the side of the protective shell 13 near the slide opening 11. The interior of the two through slots 14 is connected to the interior of the long slot 19. Two square rods 15 are respectively movably connected to the interior of the two through slots 14.

[0024] Two square rods 15 are fixedly connected to a connecting rod 21 on their adjacent sides. A circular elastic rope 26 is provided between the two connecting rods 21. The two ends of the circular elastic rope 26 are respectively fixedly embedded in the adjacent ends of the two connecting rods 21, and the two connecting rods 21 are connected by the circular elastic rope 26.

[0025] The interior of the long groove 19 is provided with a movable groove 17, which is connected to the exterior of the protective shell 13. A pull plate 18 is movably connected inside the movable groove 17. A gripping groove 25 is provided inside the pull plate 18, which is connected to both sides of the exterior of the pull plate 18. The pull plate 18 is located between two connecting rods 21, and the end of the pull plate 18 inside the long groove 19 is convex. Lateral grooves 24 are provided on the upper and lower sides of the exterior of the pull plate 18. A connecting rope 27 is fixedly connected to the inner wall of each lateral groove 24. The end of the connecting rope 27 away from the lateral groove 24 is fixedly connected to the inner wall of the movable groove 17.

[0026] When using,

[0027] The first step involves placing the protective shell 13 inside the slide groove 11, while the protective shell 13 simultaneously drives the square rod 15 into the groove 23. At this point, the square rod 15 and... Card Block Both 16 are located inside the groove 23. The pull plate 18 is moved into the long groove 19. The pull plate 18 pushes the two connecting rods 21 towards each other, and the pull plate 18 drives the two connecting rods 21 to move away from each other. At this time, the connecting rods 21 drive the square rods 15 on both sides and... Card Block 16 moves into the positioning groove 22, and after the pull plate 18 enters between the two connecting rods 21 and fully expands the two connecting rods 21, the pull plate 18 clamps the two connecting rods 21 in the movable groove 17 through the elastic force generated by the circular elastic rope 26, and firmly and quickly installs the protective shell 13 on the outside of the swing arm, thereby protecting the swing arm. When the mechanical metronome is transported, the swing arm can be protected by the protective shell 13. In addition, the inside of the protective shell 13 is provided with sponge. When the swing arm hits the inside of the protective shell 13, the sponge can cushion the impact, thereby preventing the swing arm from shaking and being damaged, ensuring the normal use of the mechanical metronome, and extending the service life of the mechanical metronome. At the same time, when it is needed, the pull plate 18 can be pulled out to separate the protective shell 13 from the metronome body 1, achieving the effect of protecting the swing arm while facilitating user use.

[0028] The second step is to remove the protective shell 13 from the inside of the slide 11 and place it upside down between the two mounting plates 12, with the narrow side of the protective shell 13 located below the two mounting plates 12 and the wide side of the protective shell 13 located above the two mounting plates 12. The protective shell 13 can be placed through the two mounting plates 12, which is convenient for the user to take it out when it is necessary to close the protective shell 13 with the metronome body 1.
