[0010] Preferably, the rotating frame assembly includes a rotating frame body, shaft hole frames are arranged at both ends of the rotating frame body, and a limiting card slot is also opened on one side of the rotating frame body.

[0011] Preferably, the light bar is fixedly clamped inside the limiting card slot, and the rotating frame body is rotatably clamped on the shaft rod through the shaft hole frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects: through the fixed splint assembly and the movable splint assembly, the staff can easily clamp the outside of the invar tape, thus facilitating the quick installation and disassembly of the equipment, improving the work efficiency, and at the same time avoiding the problem of the light shaking when manually assisted lighting; when the light bar is turned on, it can provide uniform and concentrated lighting to ensure that the bar code on the invar tape is clearly visible even in a dim environment; since the rotating frame assembly is rotatably clamped on the shaft rod, the staff can conveniently adjust the angle of the light bar to ensure that the light can accurately irradiate the part of the bar code that needs to be read.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown:

[0021] Embodiment 1: The present invention provides an electronic level uniform illumination reading device, including: a clamping mechanism 1, including a fixed splint assembly 11, a movable splint assembly 12 arranged on the fixed splint assembly 11, shaft rods 13 arranged at both ends of the fixed splint assembly 11, and a power supply 14 fixedly connected to the outside of the fixed splint assembly 11; a lighting mechanism 2, including a rotating frame assembly 21 rotatably clamped on the shaft rod 13, a light bar 22 installed in the rotating frame assembly 21, and the power supply 14 and the light bar 22 are electrically connected;

[0022] Among them, when in use, hold the Invar scale 3 with one hand, hold the fixed splint assembly 11 with the other hand and push the movable splint assembly 12 away. After the fixed splint assembly 11 and the movable splint assembly 12 move onto the Invar scale 3, release the movable splint assembly 12 so that the fixed splint assembly 11 and the movable splint assembly 12 approach each other and clamp on the Invar scale 3. Rotate the rotating frame assembly 21 around the fixed splint assembly 11 through the shaft rod 13. When the light bar faces the bar code scale on the Invar scale 3, turning on the light bar 22 can play an auxiliary lighting role, thus facilitating the staff to use it in a dim environment.

[0023] Specifically, the fixed splint assembly 11 includes a fixed splint body 111, a handle 112 fixedly connected to the fixed splint body 111, and a first rubber strip 113 fixedly connected to one side of the fixed splint body 111.

[0024] Specifically, the movable splint assembly 12 includes a movable splint body 121. A second rubber strip 122 is fixedly connected to one side of the movable splint body 121. A guide rod 123 is also fixedly connected to the outside of the movable splint body 121. A spring 124 is sleeved on the outside of the guide rod 123.

[0025] Specifically, the fixed splint body 111 is slidably clamped on the guide rod 123 in a limited manner, and the spring 124 drives the fixed splint body 111 and the movable splint body 121 to approach each other.

[0026] As can be seen from the above, after holding the handle 112, pushing the guide rod 123 can cause the movable splint body 121 to move away from the fixed splint body 111. At the same time, the spring 124 will be compressed. The fixed splint body 111 and the movable splint body 121 are jointly clamped on the outside of the invar scale 3. After releasing the guide rod 123, the reset of the spring 124 will cause the guide rod 123 to drive the movable splint body 121 to move. The movement of the movable splint body 121 will approach the fixed splint body 111, so as to clamp and fix on the outside of the invar scale 3. The first rubber strip 113 and the second rubber strip 122 can prevent the invar scale 3 from being worn, and at the same time can achieve a good anti-slip effect and prevent the equipment from moving.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the rotating frame assembly 21 includes a rotating frame body 211. Shaft hole frames 212 are provided at both ends of the rotating frame body 211. A limit card slot 213 is also opened on one side of the rotating frame body 211.

[0028] Specifically, the light bar 22 is fixedly clamped inside the limit card slot 213, and the rotating frame body 211 is rotationally clamped on the shaft rod 13 through the shaft hole frame 212.

[0029] As can be seen from the above, rotate the rotating frame body 211 around the shaft rod 13 through the shaft hole frame 212 and stop when the light bar 22 faces the invar scale 3. At this time, by turning on the light bar 22, it can illuminate the bar code scale on the invar scale 3. The limit card slot 213 can facilitate the placement and fixation of the light bar 22, and the power supply 14 can illuminate the light bar 22.
