[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The resonant rod of the crystal resonator according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the resonant rod of the crystal resonator of the embodiment of the utility model includes a resonant rod body 2, wherein a covering mechanism 1 is installed on the surface of the resonant rod body 2, and locking and spring mechanisms 3 are arranged on both sides of the resonant rod body 2. The covering mechanism 1 may include two first arc plates 101, multiple second arc plates 102, multiple rotating shafts 103 and torsion springs 105.

[0023] Among them, a connecting block 104 is installed on one side of the two first arc plates 101, and a connecting block 104 is installed on both sides of the multiple second arc plates 102. The connecting blocks 104 corresponding to the two first arc plates 101 and the multiple second arc plates 102 are installed alternately, and a rotating shaft 103 is installed through the multiple connecting blocks 104. A torsion spring 105 is installed in the middle of the multiple rotating shafts 103, and both ends of the torsion spring 105 are respectively installed on the surfaces of the adjacent first arc plates 101 and the second arc plates 102. A bottom plate 4 is installed on the bottom of the two first arc plates 101. The second arc plates 102 on both sides of the first arc plate 101 are rotatably connected to the first arc plate 101, and the first arc plate 101 on the same side and the second arc plates 102 on both sides thereof form an arc surface and are sleeved on the resonance rod body 2.

[0024] Specifically, the provided covering mechanism 1 is capable of covering the surface of the resonance rod body 2, rotating the second arc plate 102 to increase the angle between the second arc plate 102 and the first arc plate 101, placing the resonance rod body 2 on the surface of the bottom plate 4, and slowly releasing the second arc plate 102. The second arc plate 102 will return to its initial state under the action of the torsion spring 105, thereby achieving the covering of the resonance rod body 2.

[0025] The locking mechanism 3 may include two elastic sheets 303, a locking ball 304, a telescopic rod 305, a spring 306 and a screw 301, wherein a cylindrical groove 302 is provided through the middle of the first arc plate 101, and two opposite elastic sheets 303 are installed at the end points of the cylindrical groove 302. The tops of the two elastic sheets 303 are arc-shaped, and a locking ball 304 is installed on one side of the elastic sheet 303. The surface of the locking ball 304 is fixedly connected to one end of the telescopic rod 305. A movable cavity 307 is provided inside the screw 301, and the other end of the telescopic rod 305 is arranged inside the movable cavity 307. The surface of the locking ball 304 is connected to one end of the spring 306, and the other end of the spring 306 is connected to the top of the screw 301. The inner wall of the cylindrical groove 302 is provided with an internal thread 308, and the surface of the screw 301 is provided with an external thread 309 matching the internal thread 308.

[0026] When in use, the screw rod 301 is rotated to drive the spring 306, the telescopic rod 305 and the engaging ball 304 to move. When the engaging ball 304 moves to the inside of the elastic sheet 303, the screw rod 301 is continuously rotated until it stops. When the resonant rod column is subjected to horizontal force, it will move toward the front end of the elastic sheet 303, and the elastic sheet 303 will continue to move toward the engaging ball 304. At this time, the engaging ball 304 transmits force to the spring 306 to buffer the impact force, thereby reducing the impact force on the resonant rod body 2.

[0027] It should be noted that the provided covering mechanism 1 can cover the surface of the resonance rod to protect the surface of the resonance rod, and the provided locking and spring mechanism 3 has one function of clamping the two sides of the resonance rod body 2, and another function of buffering the impact force.

[0028] In one embodiment of the present invention, Figure 2 and 3 As shown, the bottoms of the two elastic sheets 303 are arc-shaped.

[0029] Specifically, the bottom of the elastic sheet 303 is configured to be in an arc shape, so that the engaging ball 304 can be easily moved between the two elastic sheets 303 and clamped by the elastic sheets 303 when moving.

[0030] In one embodiment of the present invention, Figure 2 As shown, a limit block is provided on the top of the moving cavity 307 to prevent the telescopic rod 305 from moving out.

[0031] Furthermore, when the screw rod 301 is rotated and moved out, the telescopic rod 305 can be moved out at the same time through the limiting block.

[0032] In one embodiment of the present invention, Figure 1 As shown, the cylindrical grooves 302 opened on the surfaces of the two first arc plates 101 correspond to each other.

[0033] Specifically, when the resonance rod body 2 is clamped, the resonance rod can be subjected to a stable and balanced force.

[0034] In one embodiment of the present invention, Figure 2 As shown, the distance between the bottoms of the two elastic sheets 303 is smaller than the diameter of the engaging ball 304 .

[0035] It should be noted that the setting of the bottom distance of the elastic sheet 303 can prevent the ball from moving out.

[0036] Specifically, in the actual implementation process, the second arc plate 102 is rotated to increase the angle between the second arc plate 102 and the first arc plate 101, the resonance rod body 2 is placed on the surface of the bottom plate 4, and the second arc plate 102 is slowly loosened. The second arc plate 102 will return to its initial state under the action of the torsion spring 105, and the resonance rod body 2 can be covered. After that, the screw rod 301 is rotated to make the screw rod 301 drive the spring 306, the telescopic rod 305 and the locking ball 304 to move. When the locking ball 304 moves to the inside of the elastic sheet 303, the screw rod 301 is continuously rotated until it can no longer be rotated, thereby achieving protection and buffering of the resonance rod body 2.

[0037] In summary, the resonance rod of the crystal resonator of the embodiment of the utility model can alleviate the impact force on the resonance rod body 2 in the horizontal direction, protect the surface of the resonance rod body 2, and thus increase the service life of the resonance rod.
