[0029] Secondly, medical staff can operate the expansion mechanism 4 multiple times according to needs, so that the lampshade 5 on the upper end of the observation lamp 1 is expanded or retracted to a specified range, so that the protection range of the lampshade 5 can be adjusted accordingly according to the size of the irradiation range of the affected part.

[0030] In a further embodiment, referring to Figure 1 and Figure 2As shown, the clamping member 3 includes a connecting seat 31, a first clamping plate 32, a second clamping plate 33, a push rod 34, a connecting plate 35 and a telescopic spring 36. The connecting seat 31 is fixedly arranged on the end of the support rod 11 away from the observation lamp 1. The temperature controller 7 is installed on the connecting seat 31. The first clamping plate 32 is vertically fixedly arranged on one side of the connecting seat 31. The second clamping plate 33 is vertically arranged on the side of the first clamping plate 32 away from the connecting seat 31. The push rod 34 has two symmetrical and horizontally arranged between the first clamping plate 32 and the second clamping plate 33. The same end of the two push rods 34 is connected to the lower position of the second clamping plate 33. The two push rods 34 are fixedly connected, and the other ends of the two push rods 34 extend outward through the first clamping plate 32. The connecting plate 35 is located at the ends of the two push rods 34 extending out of the first clamping plate 32. The connecting plate 35 is fixedly connected to one end of the two push rods 34 extending out of the first clamping plate 32. A handle 351 is fixedly arranged on the connecting plate 35. The number of the telescopic springs 36 is the same as the number of the push rods 34 and corresponds one to one. The telescopic springs 36 are sleeved to the corresponding push rods 34 located at the first clamping plate 32 and the second clamping plate 33. The two ends of the telescopic springs 36 are respectively fixedly connected to the sides of the first clamping plate 32 and the second clamping plate 33 that are close to each other.

[0031] The second clamping plate 33 is restricted to one side of the first clamping plate 32 by two push rods 34, and the two push rods 34 are fixedly connected together through one end of the first clamping plate 32 by a connecting plate 35. When the medical staff uses the clamping member 3 at the end of the support rod 11, the medical staff can press the handle 351 on the connecting plate 35 to drive the two push rods 34 on the first clamping plate 32 to push toward the second clamping plate 33, so that the gap between 32 and 33 is expanded, so as to clamp both sides of the bed beam support;

[0032] When the first clamping plate 32 and the second clamping plate 33 are respectively located on both sides of the bed beam support, the telescopic spring 36 mounted on the two push rods 34 will be stretched accordingly, and the medical staff can stop pressing the handle 351. At this time, the telescopic spring 36 will automatically retract and drive the second clamping plate 33 to approach the first clamping plate 32, so that the first clamping plate 32 and the second clamping plate 33 can clamp both sides of the bed beam support. In this way, the entire warming observation lamp can be installed on the bed beam support of the bed, thereby reducing the space occupied on the ground and will not hinder the movement of medical staff and the placement of medical equipment on the ground.

[0033] In a further embodiment, referring to Figure 4As shown, a first abutment strip 321 is fixedly provided at a top position of one side of the first clamping plate 32 close to the second clamping plate 33, and a second abutment strip 331 is fixedly provided at a top position of one side of the second clamping plate 33 close to the first clamping plate 32;

[0034] When the first clamping plate 32 and the second clamping plate 33 clamp the horizontal bracket of the bed beam, the first abutment bar 321 and the second abutment bar 331 will abut against the top of the horizontal bracket of the bed beam, so that the first clamping plate 32 and the second clamping plate 33 will not slide down after clamping the horizontal bracket of the bed beam.

[0035] In a further embodiment, referring to Figure 1 , Figure 5 and Figure 6 As shown, the spreading mechanism 4 includes a connecting rod 41, a rotating rod 42, a self-locking member 43 and an extension rod 44. The end of the connecting rod 41 is arranged on the mounting seat 2. The end of the connecting rod 41 is fixedly provided with an embedding block 411. The mounting seat 2 is provided with an embedding groove 21 for embedding the embedding block 411. The rotating rod 42 is arranged at one end of the connecting rod 41 away from the mounting seat 2. The end of the rotating rod 42 is hinged to the front end of the connecting rod 41. The self-locking member 43 is arranged between the connecting rod 41 and the rotating rod 42. The extension rod 44 is arranged at the front end of the rotating rod 42. The front end of the rotating rod 42 is provided with a slot 421 for inserting the extension rod 44.

[0036] The embedding groove 21 provided on the mounting seat 2 allows the embedding block 411 provided at the end of the connecting rod 41 to be directly embedded in the corresponding embedding groove 21 provided on the mounting seat 2, so that the connecting rod 41 can be easily disassembled and assembled. Since the front end of the connecting rod 41 is provided with a rotating rod 42, and the end of the rotating rod 42 is directly hinged to the front end of the connecting rod 41, when it is necessary to adjust the opening size of the lampshade 5, the rotating rod 42 can be operated to rotate upward along the front end of the connecting rod 41 to a specified angle, and the rotating rod 42 will drive the lampshade 5 covering the observation lamp 1 to be opened together, so that the opening size of the lampshade 5 can be changed;

[0037] By setting the self-locking part 43, the rotating rod 42 can be rotated to a specified angle and then be restricted on the connecting rod 41 and no longer rotate. When the lampshades 5 covered by the medical staff are of different sizes, it is only necessary to extend and retract the rod inserted in the slot 421 at the front end of the rotating rod 42, thereby increasing the length of the rotating rod 42 itself to cope with lampshades 5 of different sizes.

[0038] In a further embodiment, referring to Figure 7 and Figure 8As shown, the front end of the connecting rod 41 is provided with connected placement grooves 412 on both sides, and the self-locking member 43 includes a moving block 431, a connecting frame 432, a rotating wheel 433, a pushing spring 434 and a positioning latch 435. The moving block 431 is movably arranged in the placement groove 412 provided at the front end of the connecting rod 41, and the connecting frame 432 is arranged at the lower part of the front end of the connecting rod 41. Both sides of the end of the connecting frame 432 are fixedly connected to the corresponding sides of the moving block 431. The rotating wheel 433 is rotatably arranged at the front end of the connecting frame 432, and the rolling surface of the rotating wheel 433 is aligned with the rotating rod 42. The bottom surface is abutted, the push spring 434 is arranged in the placement groove 412 opened by the connecting rod 41 and is located between the end of the moving block 431 and the rear side wall of the placement groove 412, the two ends of the push spring 434 are respectively fixedly connected with the end of the moving block 431 and the rear side wall of the placement groove 412, the positioning pin 435 is arranged above the front end of the connecting rod 41, and the upper surface of the front end of the connecting rod 41 is provided with a plurality of positioning holes 413 penetrating the placement groove 412 and for the positioning pin 435 to be inserted, and the top of the moving block 431 is provided with a socket 4311 for the positioning pin 435 to be inserted;

[0039] When the rotating rod 42 needs to rotate along the connecting rod 41, the medical staff needs to first pull out the positioning pin 435 from the positioning hole 413 provided on the connecting rod 41, so as to disengage the front end of the positioning pin 435 from the socket 4311 provided on the top of the moving block 431. Then the medical staff can push the connecting frame 432 to make the moving block 431 move forward in the placement groove 412 provided on the connecting rod 41. At this time, the pushing spring 434 in the placement groove 412 will also provide forward pushing power, making it easier for the moving block 431 to move forward in the placement groove 412. While the moving block 431 and the connecting frame 432 move forward on the connecting rod 41, the rotating wheel 433 on the connecting frame 432 will roll forward along the bottom surface of the rotating rod 42 When the rotating wheel 433 rolls, it will drive the end of the rotating rod 42 to rotate upward along the front end of the connecting rod 41, so as to open the lampshade 5. When the rotating rod 42 stops rotating, the socket 4311 opened at the top of the moving block 431 will be directly below one of the positioning holes 413 opened on the connecting rod 41. Then the medical staff will insert the positioning pin 435 through its positioning hole 413 into the socket 4311 at the top of the moving block 431 again, so that the moving block 431 cannot continue to move in the placement groove 412 opened on the connecting rod 41. At this time, the rotating wheel 433 on the connecting frame 432 will stop rolling, and the bottom of the rotating rod 42 will overlap on the rotating wheel 433 and will no longer rotate, thereby temporarily restricting the rotating rod 42.

[0040] In a further embodiment, referring to Figure 3 As shown, a base 6 is fixedly provided on one side of the bottom of the first clamping plate 32 away from the second clamping plate 33, a mobile power source 61 is provided at the bottom of the base 6, and the mobile power source 61 is electrically connected to the observation light 1, and a card plate 62 is fixedly provided on both sides of the bottom of the base 6, and card slots 611 are provided on both sides of the outside of the mobile power source 61 to be mutually engaged with the two card plates 62 on the base 6;

[0041] When the device is used in a power-off state, the mobile power supply 61 can be used as a backup power supply. After the power supply 61 is placed under the base 6 at the bottom of the first clamping plate 32, the card plates 62 provided on both sides of the bottom of the base 6 can be used to embed the mobile power supply 61 into the corresponding card slots 611 on both sides of the outside of the mobile power supply 61, thereby completing the installation of the mobile power supply 61.
