[0040] See also Figure 1-5 The utility model provides a technical solution: a novel lamp holder reflector screen, comprising a mounting seat 1 and a rotating seat 3. A rotating seat groove 5 is provided on the upper surface of the mounting seat 1. The rotating seat 3 is rotatably connected inside the rotating seat groove 5. A plurality of second return spring grooves 15 are provided inside the rotating seat groove 5. The left and right sides of the mounting seat 1 are fixedly connected with mounting blocks 4. A plurality of second limiting block grooves 14 are provided on the outer surface of the rotating seat 3. Second limiting blocks 16 are slidably connected inside the plurality of second return spring grooves 15. One end of the plurality of second limiting blocks 16 close to the second limiting block groove 14 is respectively in contact with the inner wall of the corresponding second limiting block groove 14. Second return springs 17 are fixedly connected inside the plurality of second return spring grooves 15. One end of the plurality of second return springs 17 close to the second limiting block 16 is respectively fixedly connected with one end of the corresponding second limiting block 16. An adjusting device is provided on the rotating seat 3.

[0041] The adjusting device comprises a fixed seat 8 which is fixedly connected to the upper surface of the rotating seat 3 , a support seat 10 is fixedly connected to the upper surface of the fixed seat 8 , and a mounting head groove 6 is formed on the front outer surface of the support seat 10 .

[0042] The mounting head slot 6 has a mounting head 7 rotatably connected therein, one end of the mounting head 7 close to the mounting head slot 6 has a plurality of first limit blocks 11 slidably connected therein, and the mounting head slot 6 has a plurality of first limit block slots 12 formed therein.

[0043] Among them, the first return springs 13 are fixedly connected in the multiple grooves opened inside the installation head 7, and the ends of the multiple first return springs 13 close to the first limit block 11 are fixedly connected to the ends of the corresponding first limit blocks 11 respectively.

[0044] The outer wall of the fixing block on the fixing seat 8 is rotatably connected with the reflective screen 2 , and one end of the plurality of first limiting blocks 11 close to the first limiting block groove 12 is in contact with the inner wall of the corresponding first limiting block groove 12 .

[0045] The outer surface of the fixing seat 8 is fixedly connected with a hydraulic telescopic rod 9, which is "tilted". The output end of the hydraulic telescopic rod 9 is rotationally connected to the opposite surfaces of the two fixing plates on the lower surface of the reflection screen 2.

[0046] Furthermore, when the device is used, it is started by connecting an external power supply, first the mounting base 1 is installed at the designated position through the mounting block 4, and then the special lamp is installed on the mounting head 7, and then the hydraulic telescopic rod 9 is started, and the angle of the reflective screen 2 is adjusted through the hydraulic telescopic rod 9, and then the special lamp is started to illuminate the designated position.

[0047] Furthermore, when the irradiation position needs to be adjusted, the special lamp can be directly rotated, and then the mounting head 7 can be driven to rotate when the special lamp rotates. Then the first limit block 11 on the mounting head 7 continuously changes its position and contacts the inside of the first limit block groove 12 while the mounting head 7 rotates, thereby limiting the mounting head 7 and preventing the mounting head 7 from being unable to rotate without external force. Then, the hydraulic telescopic rod 9 can be started to adjust the angle of the reflective screen 2 while changing the irradiation position of the special lamp. Then, the fixed seat 8 is rotated, and the rotating seat 3 is driven to rotate by the rotation of the fixed seat 8, while the second limit block 16 continuously changes its position and contacts the inside of the second limit block groove 14, thereby limiting the rotating seat 3. In this way, the irradiation direction of the special lamp can be adjusted.

[0048] The special lamp is rotated by rotating the special lamp in the adjustment device, and then the mounting head 7 is driven to rotate when the special lamp rotates. Then the first limit block 11 on the mounting head 7 continuously changes its position and contacts with the inside of the first limit block groove 12 while the mounting head 7 rotates. Then the hydraulic telescopic rod 9 is started to adjust the angle of the reflective screen 2 and change the irradiation position of the special lamp. This avoids the need for staff to use tools to adjust the irradiation position of the special lamp, effectively reduces the workload of the staff, and facilitates the adjustment of the special lamp by the staff. The fixed seat 8 is rotated to drive the rotating seat 3 to rotate, and at the same time, the second limit block 16 continuously changes its position and contacts with the inside of the second limit block groove 14, so as to limit the rotating seat 3. In this way, the irradiation direction of the special lamp can be adjusted, which is convenient for the staff to adjust the irradiation direction of the special lamp, greatly improving the practicality and flexibility of the equipment.

[0049] Working principle: first, install the mounting seat 1 at the designated position through the mounting block 4, then install the special lamp on the mounting head 7, and then start the hydraulic telescopic rod 9, adjust the angle of the reflective screen 2 through the hydraulic telescopic rod 9, and then start the special lamp to irradiate the designated position. When the irradiation position needs to be adjusted, the special lamp can be directly rotated to rotate, and then the mounting head 7 is driven to rotate when the special lamp rotates. Then, the first limit block 11 on the mounting head 7 continuously changes its position and contacts with the inside of the first limit block groove 12 while the mounting head 7 rotates, so as to limit the mounting head 7 and prevent the mounting head 7 from rotating without external force. Then, starting the hydraulic telescopic rod 9 can adjust the angle of the reflective screen 2 and change the irradiation position of the special lamp. Then, rotate the fixed seat 8, and drive the rotating seat 3 to rotate through the rotation of the fixed seat 8, while making the second limit block 16 continuously change its position and contact with the inside of the second limit block groove 14, so as to limit the rotating seat 3, so that the irradiation direction of the special lamp can be adjusted.
