Embodiment 2

[0025] In addition to all the technical features of the first embodiment, the present embodiment also includes: a left limit block 3 is fixedly installed on the lower end of the inner wall of the vacuum tank 1, and a right limit block 4 is also arranged on the opposite surface of the left limit block 3. The left limit block 3 and the right limit block 4 are symmetrically located at the center position of the inner lower end of the vacuum tank 1. A fixing hole 5 is opened above the left limit block 3 and the right limit block 4. A slide groove 15 is opened on the inner side of the left limit block 3 and the right limit block 4. A second clamping block seat 14 is slidably connected inside the slide groove 15. The second clamping block seat 14 is located at the rear end of the left limit block 3 and the right limit block 4. The rear end of the adjustable connecting rod 11 is connected to the second clamping block seat 14. The front end outer wall of the left limit block 3 and the right limit block 4 is fixedly installed with The first clamping block seat 13, the second clamping block seat 14 and the top of the first clamping block seat 13 are provided with a clamping block mounting groove 16, and a detachable clamp 17 is fixedly installed above the clamping block mounting groove 16.

[0026] Working principle:

[0027] First, place the tool to be coated in the clamping block installation groove 16 between the first clamping block seat 13 and the second clamping block seat 14. According to the size of the tool, select and install a suitable detachable clamp 17, and fix it above the clamping block installation groove 16 through the clamp fixing block 18 to ensure that the tool is stably clamped. At the same time, fix the left limit block 3 and the right limit block 4 to the lower end of the inner wall of the vacuum tank 1 through the fixing hole 5 to improve the stability of the overall device.

[0028] Secondly, when the tool needs to be clamped, operate the lever 10 to rotate it. The rotation of the lever 10 drives the first connecting rod 7 to move toward the front end of the limit base 6, and at the same time links the second connecting rod 8 and the third connecting rod 9 to move the adjustable connecting rod 11 backward. Since the adjustable connecting rod 11 is connected to the second clamping block seat 14, the second clamping block seat 14 slides backward in the slide groove 15 of the left limit block 3 and the right limit block 4, and cooperates with the first clamping block seat 13 to clamp the tool. After the clamping is stable, close the tank cover 2, start the vacuum coating equipment, and coat the tool in a vacuum environment. The stability and adaptability of the clamping fixture ensure that the tool maintains the correct position and posture, thereby ensuring the quality and uniformity of the coating.

[0029] Finally, after the coating is completed, the lever 10 is operated again to slide the second clamping block seat 14 forward to release the tool. The can lid 2 is opened to take out the coated tool. The flexible design of the clamping block mounting groove 16 allows easy installation and adjustment of the detachable clamp 17, which improves the versatility and flexibility of the clamping fixture.
