[0075] At the same time, in the present invention, the lower end of the support frame 5 is required to be designed as a plug-in end, and is required to be able to be inserted into the plug-in hole 15 of the base 1.

[0076] The present invention can realize the rapid installation and disassembly of the support frame 5 on the base 1 through the design of the plug-in part: the plug-in method allows the support frame 5 to be quickly installed on the base 1 of the tuning fork unit 101, and is also easy to disassemble, which is convenient for experimental operation and equipment maintenance; at the same time, it has good flexibility: through the plug-in method, the support frame 5 can be adjusted in position or replaced with different support frames 5 as needed to meet different experimental needs.

[0077] In the present invention, the main function of the support frame 5 is to suspend the detection ball 4: the main function of the support frame 5 is to suspend the detection ball 4 so that it can be arranged in close contact with the tuning fork to detect the vibration of the tuning fork.

[0078] In addition, the vibration detection is adjusted in the present invention: by adjusting the position of the support frame 5, the contact state between the detection ball 4 and the tuning fork can be changed, thereby optimizing the effect of the vibration detection.

[0079] Furthermore, in the present invention, the support frame 5 includes a longitudinal frame 51 and a transverse frame 52, and the transverse frame 52 is arranged perpendicular to the longitudinal frame 51; based on the above design, the support frame 5 forms an inverted L-shaped structure, and such a setting can facilitate the subsequent hanging of the detection ball 4; at the same time, it is also convenient for the arrangement and placement of the support frame 5 on the base 1.

[0080] At the same time, in the present invention, the transverse bracket 52 is connected to the longitudinal bracket 51 through an adjustment part. The setting of the adjustment part not only facilitates the connection between the transverse bracket 52 and the longitudinal bracket 51, but also realizes the lateral movement of the transverse bracket 52 on the longitudinal bracket 51.

[0081] In actual arrangement, the longitudinal bracket 51 is arranged in the vertical direction, and the transverse bracket 52 is arranged in the horizontal direction; the transverse bracket 52 suspends the detection ball 4 through the connecting rope 6 .

[0088] Pressing bolt 53: A pressing bolt 53 is provided on the longitudinal bracket 51, and the pressing bolt 53 extends into the through hole and presses on the transverse bracket 52; based on this design, it can be known that the pressing bolt 53 of the present invention is connected to the longitudinal bracket 51 through a thread, and the position of the transverse bracket 52 can be fixed or released by tightening or loosening the pressing bolt 53 during subsequent use.

[0089] Adjustment principle: when the position of the transverse bracket 52 needs to be adjusted, first loosen the pressing bolt 53; at this time, the transverse bracket 52 can slide freely in the through-hole of the longitudinal bracket 51; according to the experimental requirements, slide the transverse bracket 52 to a suitable position; after the transverse bracket 52 is adjusted to a suitable position, tighten the pressing bolt 53 so that the pressing bolt 53 presses on the transverse bracket 52, thereby fixing the position of the transverse bracket 52.

[0090] Through the design of the adjustment part, the position of the transverse bracket 52 can be flexibly adjusted according to experimental requirements, thereby increasing the applicability and versatility of the device.

[0091] At the same time, the setting of the adjustment part can realize the disassembly of the horizontal bracket 52 and the vertical bracket 51, which is convenient for the subsequent storage of the resonance device.

[0092] Furthermore, the longitudinal bracket 51 in the present invention is a telescopic bracket; the longitudinal bracket 51 of the present invention adopts a telescopic bracket to have a telescopic function: such a setting can adjust the longitudinal height of the detection ball 4 as needed, so that the detection ball 4 can match test tuning forks 2 of various heights, thereby improving the scope of application of the present invention.

[0096] In the present invention, the swing rod 31 is the main part of the swing mechanism and is fixed on the base 1; the two can be connected by a structure similar to the above-mentioned connecting part, that is, the swing rod 31 is also required to be designed as a detachable structure with the base 1, and the swing rod 31 provides an elevated fulcrum for the striking hammer 3. During subsequent use, the striking hammer 3 can be rotated around the central axis of the swing rod 31 by moving the striking hammer 3; thereby achieving the impact of the striking hammer 3 on the corresponding test tuning fork 2.

[0097] The striking hammer 3 is a component used to strike the test tuning fork, and is connected to the swing rod 31 through a rotating part; the shape and material of the striking hammer 3 are selected according to actual design requirements.

[0098] At the same time, in the present invention, the rotating part is the connecting part between the knocking hammer 3 and the swing rod 31, including a rotating sleeve 32 arranged at the tail of the knocking hammer 3; the rotating sleeve 32 is sleeved on the swing rod 31, so that the knocking hammer 3 can rotate around the central axis of the swing rod 31; the rotating sleeve 32 is a connecting component between the knocking hammer 3 and the swing rod 31; it allows the knocking hammer 3 to rotate freely on the swing rod 31, thereby realizing the knocking action; through the rotation of the knocking hammer 3 on the swing rod 31, the knocking hammer 3 can rotate around the central axis of the swing rod 31; when the swing rod 31 swings to a certain angle, the knocking hammer 3 will knock the test tuning fork 2 to make it vibrate; based on the above design, the present invention can facilitate the arrangement and placement of the knocking hammer 3, while freeing the operator's hands and reducing the problem of the operator's hands being occupied by holding the hammer.

[0099] Furthermore, in the present invention, a limiting ring rib 33 is provided on the swing rod 31; the horizontal projection area of ​​the limiting ring rib 33 is larger than the area of ​​the rotating sleeve 32; the limiting ring rib 33 is essentially a protrusion provided on the swing rod 31 to support the rotating sleeve 32 and facilitate the limitation of the position of the striking hammer 3 on the swing rod 31.

[0100] In the present invention, the limiting ring rib 33 is arranged on the swing rod 31, usually located below the rotating sleeve 32; the limiting ring rib 33 is an annular protrusion, and its horizontal projection area is larger than the area of ​​the rotating sleeve 32; the diameter of the limiting ring rib 33 is larger than the outer diameter of the rotating sleeve 32, so as to effectively limit the movement of the rotating sleeve 32; the limiting ring rib 33 is usually integrally formed with the swing rod 31, and the material is the same as that of the swing rod 31; usually metal.

[0103] There are usually several common ways of detachable connection: threaded connection: the swing arm 31 is fixed to the base 1 by threads; this method is simple and firm, suitable for scenarios that require frequent disassembly and assembly; plug-in connection: the swing arm 31 is fixed to the base 1 by plug-in; this method usually requires a locking device (such as a bolt or a buckle) to ensure the stability of the connection.

[0104] Furthermore, in the present invention, the swing mechanism and the identification unit 102 are respectively arranged on a tuning fork unit 101; the present invention is designed with two tuning fork units 101, a swing mechanism is set on one tuning fork unit 101, and an identification unit 102 is arranged on the other tuning fork unit 101.
