[0030] The hinge 44 is fixedly connected to the end away from the main shell 41 with a slider 45, and the outer wall of the slider 45 is slidably connected to the inner wall of the fixing ring 46 through a groove 48, and the groove 48 is opened in the wall of the fixing ring 46. The outer wall of the auxiliary shell 42 is fixedly connected to the buckle 43, and a block is fixed under the main shell 41, which can cooperate with the buckle 43 under the auxiliary shell 42 to limit the position of the main shell 41 and the auxiliary shell 42. The inner wall of the auxiliary shell 42 is threadedly connected to the outer wall of the screw rod 32, and the outer wall of the screw rod 32 is threadedly connected to the inner wall of the main shell 41. The end of the connecting column 47 away from the fixing ring 46 is fixedly connected to the outer wall of the mounting plate 2.

[0031] Working principle:

[0032] When in use, first place the quartz crystal at the top center of the resonator body 1, then start the proofreading mechanism 3 on the mounting plate 2, and use the proofreading mechanism 3 to correct the position of the quartz crystal. After the proofreading mechanism 3 completes the position correction of the quartz crystal, the fine-tuning mechanism 4 on the proofreading mechanism 3 can be used to make slight adjustments to the proofreading mechanism 3, thereby changing the position of the quartz crystal.

[0033] After the quartz crystal is placed on the top of the resonator body 1, the staff pulls the plug plates 38 in the proofreading mechanisms 3 on both sides at the same time to make the plug plates 38 away from the screw rod 32, thereby releasing the restriction on the screw rod 32. When the screw rod 32 is free from the restriction of the plug plates 38, the tension spring 33 releases its elastic potential energy. Because the end of the tension spring 33 away from the pull ring 31 is fixed on the support plate 36, the tension spring 33 on one side of the support plate 36 cannot move. When the tension spring 33 releases its elastic potential energy, it can only drive the screw rod 32 to the support plate 36. The resonator body 1 is moved sideways, and a proofreading mechanism 3 is provided on both sides of the resonator body 1, and a pair of screw rods 32 is provided in a group of proofreading mechanisms 3, with a total of four screw rods 32. During the sliding process of the screw rods 32, the top block 35 is synchronously driven to move toward the center of the resonator body 1. Under the continuous drive of the tension spring 33, the top block 35 is forced to clamp the quartz crystal, and under the movement of the screw rod 32, the quartz crystal is located at the center of the resonator body 1, and then the pulling force on the plug plate 38 is released, thereby completing the proofreading of the quartz crystal position.

[0034] After the quartz crystal has completed the etching work, the insert plate 38 is first kept away from the screw rod 32. The insert plate 38 compresses the compression spring 37 synchronously during the sliding process, so that the compression spring 37 accumulates elastic potential energy. Then, the staff only needs to pull the pull rings 31 on both sides to drive the screw rod 32 to move away from the quartz crystal through the pull rings 31. Under the continuous movement of the screw rod 32, the top block 35 slides back into the fixed shell 34. After the top block 35 slides back into the fixed shell 34, the pulling force on the insert plate 38 is released. When the compression spring 37 lacks the compression of the insert plate 38, the compression spring 37 releases its elastic potential energy, and is able to push the insert plate 38 to move in the direction of the screw rod 32, so that the insert plate 38 is reinserted into the threaded groove of the screw rod 32, thereby limiting the position of the screw rod 32 again and releasing the clamping of the quartz crystal.

[0035] In the process of the calibration mechanism 3 clamping the quartz crystal, the position of the screw rod 32 can be adjusted by the fine-tuning mechanism 4, so as to fine-tune the position of the quartz crystal. It is only necessary to rotate the main shell 41 and the auxiliary shell 42 along the hinge 44 to close them, and fix the positions of the main shell 41 and the auxiliary shell 42 by the buckle 43, so that the main shell 41 and the auxiliary shell 42 form a complete annular shell, and are sleeved on the screw rod 32. The inner walls of the main shell 41 and the auxiliary shell 42 are provided with thread grooves, which are engaged with the threads on the screw rod 32. Therefore, when the main shell 41 and the auxiliary shell 42 are sleeved on the screw rod 32, the shell can be rotated, and the hinge 44 on the shell is connected to the screw rod 32 through the slider 45. On the fixing ring 46, the slider 45 slides along the slide groove 48 in the fixing ring 46, thereby limiting the position of the shell, but also allowing the shell to rotate, because the fixing ring 46 is fixed to the fixing shell 34 through the connecting column 47, so that the position of the shell cannot be changed, and it can only be rotated. When the shell rotates, it drives the lead screw 32 to slide, thereby fine-tuning the position of the lead screw 32, and then fine-tuning the position of the quartz crystal. When fine-tuning is not required, it is only necessary to unlock the buckle 43 so that the buckle 43 releases the restriction on the main shell 41 and the auxiliary shell 42, so that the main shell 41 and the auxiliary shell 42 can be rotated along the hinge 44, thereby disconnecting the engagement with the lead screw 32.
