[0002] Micro-nano machining is a highly precise manufacturing technology used to fabricate structures and devices of tiny sizes, typically in the micrometer (millionth of a meter) and nanometer (billionth of a meter) scale. This technology has applications in many fields, including electronics, optics, biomedicine, nanotechnology, and materials science. The main goal of micro-nano machining is to create tiny structures and devices to achieve various functions.

[0003] In the prior art, the Chinese patent with publication number CN201721845224.8 adopts the solution of "pulling the clamping bar so that the clamping bar clamps the required product under the elastic force of the spring, and after the product is clamped, the fastening bolts can be selectively tightened according to the characteristics of the product to be processed."

[0004] However, the above scheme still has some shortcomings. For example, when in use, the two card strips are elastically connected by springs, and the method of pulling any spring to fix them is not convenient for centering the product. When taking out the product, pulling the card strip may easily cause the product to be ejected by the other card strip, which is inconvenient to operate. In view of this, the utility model proposes a micro-nano processing positioning tray. Summary of the invention

[0034] Principle and process of this utility model:

[0035] When the micro-nano processing positioning tray of the utility model is used, the pressure rod 82 is pulled, and the pressure rod 82 drives the arc-shaped pressure block 83 to separate from the driving rod 75, and then the driving rod 75 is rotated. The driving rod 75 is driven by the transmission member 76 to rotate the rotating shaft 71. When the rotating shaft 71 rotates, the winding roller 72 drives the pull rope 74 to move, and the pull rope 74 pulls the slide block 6 to move to both sides, canceling the clamping of the workpiece, making it easy to take the workpiece and convenient for processing;

[0036] When the workpiece needs to be clamped, the workpiece is placed in the clamping plate 10, the driving rod 75 is rotated, and the tightening of the pull rope 74 is cancelled. Under the action of the spring on the limit rod 5, the slider 6 drives the clamping plate 10 to clamp the workpiece, and then the driving pressure rod 82 is released. Under the action of the spring on the pressure rod 82, the pressure rod 82 drives the arc pressure block 83 to limit the driving rod 75, thereby increasing the fixing effect of the workpiece.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
