[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a frame 5 supports a quartz resonator, including a base 1, a crystal 2 is disposed on the base 1, a pin 3 is disposed at the lower end of the base 1, and a protective mechanism 4 is disposed on the base 1 to prevent the pin 3 from bending.

[0026] The protective mechanism 4 includes a protective sleeve 41, a movable sleeve 42, a slider 43, a mounting groove 44, a mounting rod 45, and a spring 46. The lower end of the base 1 is fixedly connected to the protective sleeve 41, the outer side of the movable sleeve 42 is fixedly connected to the slider 43, the inner wall of the protective sleeve 41 is provided with a mounting groove 44, the mounting rod 45 is fixedly connected in the mounting groove 44, and the outer side of the mounting rod 45 is fitted with a spring 46.

[0027] This utility model uses the various components of the above protection mechanism 4 in combination. When the pin 3 is connected to the line, the movable sleeve 42 can be pushed first to slide into the protective sleeve 41. Then the pin 3 is connected to the line. At this time, the elasticity of the spring 46 can make the slider 43 move. The movement of the slider 43 will drive the movable sleeve 42 fixed on it to move. At this time, the length of the pin 3 protruding can be reduced by the movable sleeve 42, reducing the possibility of the pin 3 being bent.

[0028] One end of the spring 46 is fixedly connected to the slider 43, and the other end of the spring 46 is fixedly connected to the mounting groove 44.

[0029] During the process of the movable sleeve 42 sliding into the protective sleeve 41, the slider 43 fixed on its outer side will compress the spring 46, causing the spring 46 to generate elastic force. Then, under the action of the elastic force of the spring 46, the slider 43 can move, thereby driving the movable sleeve 42 to move.

[0030] Pin 3 is slidably connected to the inner wall of the movable sleeve 42, and the movable sleeve 42 is slidably connected to the inner wall of the protective sleeve 41.

[0031] The movable sleeve 42 can protect pin 3 and prevent it from bending. Pin 3 may break directly if it is bent multiple times, which will affect the normal use of the resonator.

[0032] The slider 43 is slidably connected to the mounting groove 44, and the slider 43 is slidably connected to the outside of the mounting rod 45.

[0033] During the movement of slider 43, both mounting rod 45 and mounting groove 44 can guide slider 43, and mounting rod 45 can be used to install spring 46.

[0034] A frame 5 is fixedly connected to the upper end of the base 1, and a Kovar ring 6 is provided at the upper end of the frame 5. The upper end of the Kovar ring 6 contacts a cover plate 7.

[0035] The frame 5 can support the device, and the top of the Kovar ring 6 is fused together with the nickel and silver layer plated on the surface of the metal Kovar ring 6 by laser welding.

[0036] The Kovar ring 6 has a threaded groove 8, and the cover plate 7 is provided with an installation mechanism 9 that can connect the cover plate 7 and the Kovar ring 6.

[0037] The entire device can be sealed using the cover plate 7.

[0038] The mounting mechanism 9 includes a bolt 91, a nut 92, an annular groove 93, and an elastic block 94. The bolt 91 is rotatably connected to the cover plate 7 and is threadedly connected to the threaded groove 8. The upper end of the bolt 91 is fixedly connected to the nut 92. The nut 92 has an annular groove 93, and the elastic block 94 is slidably connected in the annular groove 93.

[0039] This utility model utilizes the coordinated operation of various components in the above-mentioned installation mechanism 9. By rotating the nut 92, the bolt 91 fixed on the nut 92 rotates, causing threaded movement between the bolt 91 and the threaded groove 8 inside the Kovar ring 6. This allows the bolt 91 to move into the threaded groove 8. During this process, the elastic block 94 is first compressed. Subsequently, when the nut 92 moves to the appropriate position, the elastic block 94 will be engaged in the annular groove 93 inside the nut 92 under the elastic action. This effectively prevents the bolt 91 from loosening after prolonged use, thus preventing problems with the installation of the cover plate 7.

[0040] Nut 92 contacts the upper end of cover plate 7, and elastic block 94 is fixedly connected to the upper end of cover plate 7.

[0041] Elastic Block 94 is an elastic product with high elasticity.

[0042] In practical use, during the process of connecting pin 3 to the circuit, the movable sleeve 42 can be pushed first to slide into the protective sleeve 41. Then, pin 3 is connected to the circuit. During the process of the movable sleeve 42 sliding into the protective sleeve 41, the slider 43 fixed on its outer side will compress the spring 46, causing the spring 46 to generate elastic force. Then, under the action of the elastic force of the spring 46, the slider 43 can move, thereby driving the movable sleeve 42 to move. At this time, the length of pin 3 protruding can be reduced by the movable sleeve 42, reducing the possibility of pin 3 being bent. Pin 3 may break directly after being bent multiple times, which will affect the normal use of the resonator. During the movement of the slider 43, the mounting rod 45 and the mounting groove 44 can guide the slider 43, and the mounting rod 45 can be used to install the spring 46.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
