[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 4 , Figure 7 and Figure 8 As shown, the student behavior recorder includes a C-shaped block 1. Connecting blocks 10 are fixedly connected to the left and right sides of the top of the C-shaped block 1. A fixing mechanism 2 is attached to the inner side of the bottom of the C-shaped block 1. An installation mechanism 3 is rotatably connected to the inner side of the connecting block 10. A locking block 4 is slidably connected to the front of the installation mechanism 3. The recorder body 40 is fixedly connected to the front of the locking block 4.

[0031] The fixing mechanism 2 includes a gasket 20, the bottom of which overlaps the bottom of the inner side of the C-shaped block 1. A threaded rod 21 is fixedly connected to the bottom of the gasket 20, and the outer surface of the threaded rod 21 is threadedly connected to the inner side of the bottom of the C-shaped block 1. A handwheel 22 is fixedly connected to the bottom end of the threaded rod 21.

[0032] The mounting mechanism 3 includes a connecting rod 30. The left and right sides of the outer surface of the connecting rod 30 are rotatably connected to the inner side of the connecting block 10. A fixing plate 32 is fixedly connected to the front of the middle part of the connecting rod 30. A slot 33 is opened in the middle of the front of the fixing plate 32, and the rear side of the slot 4 is slidably connected to the inner side of the slot 33.

[0033] When installing the behavior recorder on the desktop, first, insert the groove of the C-block 1 into the edge of the desktop, aligning the fixing plate 32 with the student. Then, turn the handwheel 22, causing the threaded rod 21 at the top to rotate. The threaded rod 21 rises as it rotates, which in turn causes the top pad 20 to rise, pressing against the bottom of the desktop and fixing the C-block 1 to the edge of the desktop. Then, insert the locking block 4 on the back of the recorder body 40 into the locking slot 33, thus installing the recorder body 40 onto the front of the fixing plate 32. By facing the student directly with the recorder body 40, the student's behavior can be recorded.

[0034] like Figure 1 and Figure 3As shown, a camera 41 is fixedly connected to the top of the front of the recorder body 40, and a button 42 is fixedly connected to the bottom of the front of the recorder body 40.

[0035] When recording behavior, the recorder 40 can record the student's behavior through the camera 41, and the recorder 40 can be controlled through the button 42.

[0036] like Figure 1 and Figure 3 As shown, limit grooves 43 are provided on the left and right sides of the recorder body 40 near the bottom, and a protective plate 44 is slidably connected to the inner side of the limit grooves 43.

[0037] When recording behavior, the protective plate 44 can be pushed to slide within the limiting groove 43, thereby covering the surface of the button 42 and preventing accidental touch of the button 42. When it is necessary to control the recorder body 40, the protective plate 44 is pushed upward to move it to the top of the button 42, thereby revealing the button 42.

[0038] like Figures 4 to 7 As shown, toothed blocks 50 are fixedly connected to both the left and right sides of the connecting rod 30. A connecting ring 5 is slidably connected to the inner side of the two connecting blocks 10 away from the mounting mechanism 3. A toothed block 50 distributed in a ring is fixedly connected to the inner side of the connecting ring 5, and the outer surface of the toothed block 50 is meshed with the outer ring of the gear 31. A groove 101 distributed in a ring is provided on the inner side of the connecting block 10 away from the mounting mechanism 3.

[0039] When it is necessary to adjust the recording angle of the recorder body 40, first push the connecting ring 5 so that the connecting ring 5 slides into the connecting block 10, thereby causing the connecting ring 5 to move the inner tooth block 50 away from the surface of the gear 31. At this time, the recorder body 40 can be rotated so that the recorder body 40 drives the fixing plate 32 and the connecting rod 30 to rotate within the connecting block 10, thereby adjusting the recording angle of the recorder body 40.

[0040] like Figure 5 and Figure 6 As shown, the outer ring of the connecting ring 5 is fixedly connected to a slider 52 distributed in a ring shape, and the outer surface of the slider 52 is slidably connected to the inner side of the groove 101.

[0041] During the movement of the connecting ring 5, the slider 52 of the outer ring of the connecting ring 5 slides in the groove 101, thereby preventing the connecting rod 30 and the gear 31 from rotating and causing the connecting ring 5 to rotate, thus fixing the gear 31 and the connecting rod 30 in place.

[0042] like Figure 6 As shown, springs 51 arranged in a ring shape are fixedly connected to the opposite face of the connecting ring 5.

[0043] After adjusting the recording angle of the recorder body 40, the connecting ring 5 is released, causing the spring 51 to drive the connecting ring 5 to reset. After the connecting ring 5 is reset, the inner tooth block 50 is locked onto the surface of the gear 31, thereby fixing the gear 31 and the connecting rod 30. After the connecting rod 30 is fixed, the recording angle of the recorder body 40 is fixed.

[0044] like Figure 6 As shown, a pull ring 53 is fixedly connected to the side of the connecting ring 5 that is farther apart from the connecting ring 5.

[0045] When adjusting the recording angle of the recorder body 40, pushing the pull ring 53 will cause the pull ring 53 to move the connecting ring 5, thereby preventing fingers from getting stuck in the connecting block 10 during adjustment.

[0046] The working principle of this utility model is as follows: When it is necessary to record the student's behavior, first, the groove of the C-shaped block 1 is inserted into the edge of the table. The handwheel 22 drives the pad 20 to rise, so that the pad 20 presses against the bottom of the table, thereby fixing the device to the table for easy access. With the front of the fixing plate 32 facing the student, the locking block 4 on the back of the recorder body 40 is slid into the locking slot 33, thereby installing the recorder body 40. At this time, the student's behavior is recorded through the camera 41 on the front of the recorder body 40. When it is necessary to adjust the recording angle of the recorder body 40, first press the pull ring 53 to remove the connecting ring 5 and the toothed block 50 from the surface of the gear 31. Then, rotate the entire mounting mechanism 3 to drive the recorder body 40 to rotate, thereby adjusting its recording angle. After adjustment, release the pull ring 53, so that the spring 51 drives the connecting ring 5 and the toothed block 50 to reset, so that the toothed block 50 is locked on the surface of the gear 31, thereby fixing the recording angle of the recorder body 40.
