The mounting seat 301 is slidably connected to the inside of the connecting seat 3. The mounting seat 301 is used to fix the positions of the two tuning fork chip bodies 2. The mounting assembly fixes the position of the mounting seat 301.

[0039] A connecting electrode 4 is disposed inside the connecting seat 3 . The connecting electrode 4 is used to connect the two tuning fork wafer bodies 2 . Under the action of the connecting electrode 4 , the current on the two tuning fork wafer bodies 2 is guided.

[0040] Two connecting contacts 202 are attached to the upper surface of the connecting electrode 4, and the two connecting contacts 202 are connected to the tuning fork chip body 2. Under the action of the two connecting contacts 202 and the connecting electrode 4, the two tuning fork chip bodies 2 are connected. Through the connection between the connecting contacts 202 and the connecting electrode 4, the current on the tuning fork chip body 2 can be directed to the connecting electrode 4, so as to exchange the current on the two tuning fork chip bodies 2.

[0041] The upper surface of the connecting electrode 4 is in contact with the mounting seat 301, and two contact seats 302 are provided on the outer surface of the mounting seat 301. The two contact seats 302 are in contact with the two connecting contacts 202. By installing the mounting seat 301 in the connecting seat 3, the connection between the connecting contacts 202 and the connecting electrode 4 is made tighter under the squeezing of the two contact seats 302. At the same time, by fixing the connecting contacts 202, the tuning fork chip body 2 is fixed, so that the position of the tuning fork chip body 2 is relatively stable.

[0042] The first fixing block 303 and the second fixing block 304 are inserted into the inner wall of the mounting seat 301, and the first fixing block 303 and the second fixing block 304 are inserted into the inner wall of the connecting seat 3, and the parts of the first fixing block 303 and the second fixing block 304 located outside are in contact with the outer surface of the connecting seat 3. When the mounting seat 301 is installed inside the connecting seat 3, the first fixing block 303 and the second fixing block 304 are respectively inserted into the inner wall of the connecting seat 3, so that the first fixing block 303 and the second fixing block 304 are inserted into the inner wall of the mounting seat 3, thereby completing the fixation of the mounting seat 301. At the same time, when the first fixing block 303 and the second fixing block 304 are inserted into the mounting seat 301, the position of the mounting seat 301 is limited to ensure that the mounting seat 301 and the two contact seats 302 fix the position of the tuning fork chip body 2.

[0044] It includes a mounting base plate 7 and a sealing frame 701. The sealing frame 701 is arranged on the upper surface of the mounting base plate 7. The mounting base plate 7 and the sealing frame 701 encapsulate the connecting seat 3. Under the action of the mounting base plate 7 and the sealing frame 701, the connecting seat 3 is sealed and protected. The upper surface of the mounting base plate 7 is connected to the two connecting plugs 6. By adhering the connecting plugs 6 and the connecting seat 3 to the upper surface of the mounting base plate 7, the position of the connecting plug 6 is fixed, which is convenient for connecting with the connecting electrode 4 and the two tuning fork chip bodies 2 through the connecting plug 6. The sealing frame 701 fits with the second fixed plug 304 and the two tuning fork chip bodies 2. Under the action of the sealing frame 701, the position of the second fixed plug 304 is fixed to prevent the second fixed plug 304 from falling.

[0045] Two first limit seats 702 are fixedly connected to the upper surface of the installation base plate 7, and the two first limit seats 702 are in contact with the inner wall of the connecting seat 3. Two second limit seats 703 are fixedly connected to the lower surface of the sealing frame 701, and the second limit seats 703 are slidably connected to the inner wall of the first limit seats 702. By setting the first limit seats 702 and the second limit seats 703, it is convenient to align the installation base plate 7 and the sealing frame 701, so that the position of the installation base plate 7 and the sealing frame 701 during packaging is more accurate.

[0046] A sealing seat 8 is inserted between the installation base plate 7 and the sealing frame 701. Under the action of the sealing seat 8, the installation base plate 7 and the sealing frame 701 are sealed. Two plug-in seats 801 are fixedly connected to the inner wall of the sealing seat 8. The two plug-in seats 801 are plugged into the inner wall of the corresponding connecting plug block 6. The end of the plug-in seat 801 is connected to an external lead 802, which passes through the sealing seat 8 and extends outward.

By taking out the mounting base 301, the tuning fork chip body 2 can be replaced, and then the same movement as above is performed to install the tuning fork chip body 2. By resealing the sealing frame 701, the installation of the tuning fork chip body 2 can be completed, avoiding the situation where it is damaged and cannot be disassembled.

[0050] Working principle: When the tuning fork wafer body 2 needs to be installed, two tuning fork wafer bodies 2 are placed in the vibration arm 1, and the connection contact pieces 202 at the ends of the tuning fork wafer bodies 2 are in contact with the two connection electrodes 4, so that the current on the tuning fork wafer body 2 can be directed to the connection electrodes 4, and the current on the two tuning fork wafer bodies 2 is exchanged;

[0051] At this time, by installing the mounting seat 301 in the connecting seat 3, under the pressure of the two contact seats 302, the connection between the connecting contact piece 202 and the connecting electrode 4 is made tighter, and at the same time, by fixing the connecting contact piece 202, the tuning fork wafer body 2 is fixed, so that the position of the tuning fork wafer body 2 is relatively stable;

[0052] When the mounting seat 301 is mounted inside the connecting seat 3, the first fixing plug-in block 303 and the second fixing plug-in block 304 are respectively plugged into the inner wall of the connecting seat 3, so that the first fixing plug-in block 303 and the second fixing plug-in block 304 are plugged into the inner wall of the mounting seat 301, thereby completing the fixing of the mounting seat 301. At the same time, when the first fixing plug-in block 303 and the second fixing plug-in block 304 are plugged into the mounting seat 301, the position of the mounting seat 301 is limited, so as to ensure that the mounting seat 301 and the two contact seats 302 fix the position of the tuning fork wafer body 2;

[0053] At this time, the connection plug 6 and the connection seat 3 are adhered to the upper surface of the mounting base 7, so that the position of the connection plug 6 is fixed, so that it is convenient to connect the connection electrode 4 and the two tuning fork wafer bodies 2 through the connection plug 6, and the sealing frame 701 is correspondingly plugged in, and the sealing frame 701 is encapsulated on the outer surface of the mounting base 7 to seal and protect the connection seat 3;

[0054] At this time, the sealing seat 8 is inserted between the mounting base plate 7 and the sealing frame 701 to seal the mounting base plate 7 and the sealing frame 701. At the same time, the plug-in seat 801 is inserted into the inner wall of the connecting plug block 6. Under the action of the two connecting plug blocks 6, the external lead 802 is connected to the connecting electrode 4 and the two tuning fork chip bodies 2. By connecting the external lead 802 to the external element, the tuning fork chip body 2 is used.

[0055] When the tuning fork wafer body 2 is damaged or needs to be replaced, the sealing frame 701 is disassembled by pulling out the sealing seat 8, and the connecting seat 3 can be displayed at this time;

[0056] At this time, by pulling out the first fixing block 303 and the second fixing block 304, the mounting base 301 can be unfixed from the connecting base 3. By taking out the mounting base 301, the tuning fork chip body 2 can be replaced, and then the same movement as above is performed to install the tuning fork chip body 2. By resealing the sealing frame 701, the installation of the tuning fork chip body 2 can be completed, avoiding the situation where it is damaged and cannot be disassembled.
