[0007] A support cylinder is provided at the corner of the upper end face of the connecting plate, and a pressing handle is rotatably provided in the middle of the support cylinder;

[0008] A limit bolt is threaded to one side of the connecting plate, and the limit bolt passes through the connecting plate. One end of the limit bolt is threaded to the upper surface of the support plate, and an elastic component is provided on the lower surface of the support plate.

[0009] Preferably, a connecting rod is fixedly provided at one end of the connecting plate, the connecting rod is fixedly connected to the support plate, and the connecting rod is located inside the support groove.

[0010] Preferably, the lower surface of the inner nut of the limiting bolt contacts the upper surface of the connecting plate, there is a sliding gap between the lower surface of the connecting plate and the lower surface of the limiting bolt and the upper surface of the support plate, and there is an adjustment gap between the lower surface of the outermost end of the inclined side of the connecting plate and the upper surface of the support plate, and the distance of the adjustment gap is less than the distance of the sliding gap.

[0011] Preferably, the elastic component consists of a limiting rod, a second spring, and a positioning base. The upper end of the limiting rod is fixedly connected to the lower surface of the support plate, the positioning base is fixedly disposed at the lower end of the limiting rod, and the limiting rod is located in the middle of the second spring.

[0012] Preferably, the limiting rod is fixedly connected to the positioning chassis, and a limiting plate is fixedly connected to the upper end of the limiting rod, with the limiting plate in contact with the lower surface of the support plate.

[0013] Preferably, a fixing bolt is threaded in the middle of one side of the upper surface of the connecting plate.

This causes the strings connected to the connecting plate to form a certain arc, instantly adjusting the tension of the strings and creating a vibrato effect.

[0016] 2. When one side of the connecting plate is lifted, it is limited by the limiting bolt and the connection between the limiting bolt and the support plate, which drives the support plate to be lifted synchronously, so that the second spring is in a stretched state.

[0017] 3. With the length of the limiting rod fixed and the limiting plate at one end limiting the movement of the support plate, the reliability of the support plate's reset distance is ensured, thereby effectively preventing errors caused by the elasticity of the spring and ensuring the consistency of pitch before and after the vibrato.

[0023] 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.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 A switchable vibrato bridge in this embodiment includes a support plate 1 and a connecting plate 2 disposed on the upper surface of the support plate 1. A support groove 3 is provided through the middle of the support plate 1, and the middle of the connecting plate 2 is through the support groove 3. One end of the connecting plate 2 is fixed to one side of the upper surface of the support plate 1, and the other end of the connecting plate 2 is located above one side of the upper surface of the support plate 1.

[0026] A support cylinder 6 is provided at the corner of the upper end face of the connecting plate 2, and a pressing handle 7 is rotatably provided in the middle of the support cylinder 6;

[0027] A limit bolt 4 is threadedly connected to one side of the connecting plate 2. The limit bolt 4 passes through the connecting plate 2. One end of the limit bolt 4 is threadedly connected to the upper surface of the support plate 1. An elastic component is provided on the lower surface of the support plate 1.

[0028] First, the device is installed on the guitar and then connected to the strings to enable it to function normally. Since the connection and installation are existing technologies, they are not described in detail in this embodiment and the accompanying drawings.

[0029] At this time, by pressing the handle 7, one end of the connecting plate 2 is lifted upwards, and the other end is connected to the support plate 1 for a limit, thus creating the effect of lifting one end of the connecting plate 2, so that the connecting plate 2 is in a normal tilted state, and the string connected to the connecting plate 2 is in a certain arc, thereby instantly adjusting the tension of the string and creating a vibrato effect.

[0030] The support groove 3 allows the connecting plate 2 to move and adjust its position within the support plate 1. The limiting bolt 4 ensures that when the connecting plate 2 is pulled, it can synchronously pull the limiting bolt 4. The elastic component also ensures automatic reset after stretching, guaranteeing the device has an automatic reset function after vibration, improving its stability and accuracy. Rotating the pressing handle 7 to face outwards prevents accidental activation during use, ensuring stability during non-vibration operation. This allows for quick switching between vibrating and non-vibrating operation.

[0031] A connecting rod 5 is fixedly installed at one end of the connecting plate 2. The connecting rod 5 is fixedly connected to the support plate 1 and is located inside the support groove 3.

[0032] Based on the fixed support of the connecting rod 5 between the connecting plate 2 and the support plate 1, it is ensured that when the connecting plate 2 is lifted on one side, the force generated by the lifting can simultaneously lift the support plate 1, so that it can be lifted synchronously with the connecting plate 2, ensuring its reliable stability when vibrato is used.

[0033] The lower surface of the inner nut of the limit bolt 4 contacts the upper surface of the connecting plate 2. There is a sliding gap between the lower surface of the connecting plate 2 and the limit bolt 4 and the upper surface of the support plate 1. There is an adjustment gap between the lower surface of the outermost end of the inclined side of the connecting plate 2 and the upper surface of the support plate 1. The distance of the adjustment gap is less than the distance of the sliding gap.

[0034] The elastic component consists of a limiting rod 10, a second spring 11, and a positioning base 12. The upper end of the limiting rod 10 is fixedly connected to the lower surface of the support plate 1, and the positioning base 12 is fixedly set at the lower end of the limiting rod 10. The limiting rod 10 is located in the middle of the second spring 11.

[0035] The limiting rod 10 is fixedly connected to the positioning base 12, and the upper end of the limiting rod 10 is fixedly connected to the limiting plate, which is in contact with the lower surface of the support plate 1.

[0036] When one side of the connecting plate 2 is lifted, it is limited by the limiting bolt 4 and the connection between the limiting bolt 4 and the support plate 1, which drives the support plate 1 to be lifted synchronously, so that the spring 11 is in a stretched state.

[0037] When the vibrato ends, release the handle 7. Under the elastic reset of spring 11, the support plate 1 will automatically reset. Under the connection of the limit bolt 4, the connecting plate 2 will reset synchronously. With the length of the limit rod 10 fixed and the limit plate at one end limiting the movement of the support plate 1, the reset distance of the support plate 1 is guaranteed to be reliable, thereby effectively preventing the error caused by the elasticity of spring 11 and ensuring the consistency of pitch before and after the vibrato.

[0038] By fixing the positioning base 12 to the guitar body, the positioning rod 10 and the second spring 11 are used in a fixed position, ensuring the reliability of their use position. By setting the connection between the positioning plate and the support plate 1 to be non-contact, the arc movement of the support plate 1 is prevented from being blocked, ensuring the accuracy and reliability of the support plate 1 during vibrato movement.

[0039] A fixing bolt 8 is threaded in the middle of one side of the upper surface of the connecting plate 2. The fixing bolt 8 passes through the connecting plate 2. The lower end of the fixing bolt 8 is threaded to the upper end of the support plate 1. A spring 9 is sleeved on the outer side of the upper half of the fixing bolt 8. The upper end of the spring 9 is fixedly connected to the upper end face of the support plate 1. The upper end of the spring 9 is fixedly connected to the lower end face of the inner nut of the fixing bolt 8.

[0040] By rotating the fixing bolt 8, it extends below the connecting plate 2. Continuing to rotate the fixing bolt 8, it makes threaded contact with the support plate 1, thus fixing the fixing bolt 8 to the support plate 1. This achieves the effect of fixing and limiting the connection plate 2 to the support plate 1. Under the elastic support of the spring 9, the strength of the fixing bolt 8 during positioning is guaranteed, allowing the device to be forcibly fixed when vibrating is required.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0042] 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.
