Description

Technical Field

[0001] This invention relates to the field of vibration motor technology, specifically a split-type energy-saving vibration motor. Background Technology

[0002] A vibratory motor is a device used to provide vibration. It typically has a set of adjustable eccentric blocks installed at both ends of the drive motor shaft. The excitation force is obtained by the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks. It can be applied to general vibratory machinery.

[0003] Existing vibratory motors, such as the horizontal device with patent number CN118137738B and patent title "A Short-Axis Symmetrical Explosion-Proof Vibratory Motor," typically feature an integrated design where the drive motor and eccentric blocks are directly connected to each other via threads or other means to form a fixed, integrated structure. Therefore, adjusting the relative phase angle of the individual oscillators within the eccentric block assembly requires a cumbersome disassembly process, making operation inconvenient.

[0004] Furthermore, this type of vibratory motor requires separate adjustments to the two eccentric block groups. This can lead to inconsistencies in the relative phase angles of the two sets of oscillators after adjustment, resulting in a mismatch between the motor's output vibration and the required vibration parameters, thus affecting the vibration effect. Moreover, when the relative phase angles of the two sets of oscillators are inconsistent, some of the vibrations output by the two eccentric block groups as they rotate with the drive motor will cancel each other out, reducing the energy utilization rate of the drive motor.

[0005] Therefore, a split-type energy-saving vibration motor is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a split-type energy-saving vibration motor, which solves the problem of cumbersome adjustment process of eccentric block group by split design, and also improves the consistency of the relative phase angle of the adjusted eccentric block group.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A split-type energy-saving vibration motor includes a fixed housing, within which a drive motor is fixedly installed. Each end of the output shaft of the drive motor is provided with a vibrator (first vibrator) and a second vibrator. Two protective covers are symmetrically fixedly installed on the fixed housing, covering both ends of the drive motor's output shaft. Each end of the drive motor's output shaft is provided with an adjustment device, and both adjustment devices share an adjustment rod for synchronously adjusting the relative phase angle between the two second vibrators and their corresponding first vibrators.

[0009] Based on this design, the present invention generates vibration by driving the rotation of oscillator one and oscillator two via a drive motor. When it is necessary to change the relative phase angle between oscillator one and oscillator two, the adjustment device can be unlocked, separating oscillator one and oscillator two from their fixed state. Then, without removing the protective cover, the two oscillators two are rotated synchronously using the adjustment rod, thereby changing the phase angle between oscillator two and oscillator one. Afterwards, the adjustment device is relocked, which reconnects oscillator two and oscillator one, thus fixing and maintaining the relative phase angle between oscillator two and oscillator one. Therefore, the relative phase angle between oscillator one and oscillator two can be adjusted without removing the protective cover, which is simple to operate. Furthermore, through the synchronous adjustment of the adjustment rod, the rotation angle of the two oscillators two can remain equal throughout the adjustment process, thereby ensuring the consistency of the relative phase angle of the two eccentric block groups at both ends of the drive motor.

[0010] Preferably, the adjusting device includes a threaded hole in the protective cover, a locking cylinder disposed in the threaded hole, a thread on the outer wall of the locking cylinder for engaging with the threaded hole, and a nut portion on the locking cylinder; a push block is movably installed inside the protective cover, the push block abuts against the locking cylinder, a bearing is disposed inside the push block, a connecting shaft is fixedly installed inside the bearing, a second vibrator is fixedly installed on the end of the connecting shaft near the drive motor, and a first vibrator is fixedly installed on the output shaft of the drive motor; a first friction plate and a second friction plate are fixedly installed on the first and second vibrators respectively, and the first and second friction plates are used for abutting cooperation; an adjusting rod is rotatably mounted on the locking cylinder, and a connecting unit is provided on both the connecting shaft and the locking cylinder, the connecting unit using the rotation of the locking cylinder to connect or separate the adjusting rod from the connecting shaft.

[0011] With this configuration, when the locking cylinder is screwed into the threaded hole, the end of the locking cylinder near the drive motor will abut against and push the push block. Consequently, the connecting shaft, coaxially arranged with the output shaft of the drive motor, will also be pushed and ultimately pressed against the output shaft of the drive motor. At this time, friction plates one and two also abut tightly against each other. Under the action of friction, the connecting shaft and the output shaft of the drive motor can no longer rotate relative to each other around the axis of the connecting shaft. Therefore, the torque output by the drive motor can be transmitted to the second vibrator. At this time, the connecting unit releases the connection between the adjusting rod and the connecting shaft as the locking cylinder moves within the threaded hole. Therefore, the rotation of the connecting shaft will not cause the adjusting rod to rotate, thus preventing the adjusting rod from interfering with or affecting the movement of the connecting shaft during the operation of the vibration motor, which is beneficial for improving the motion stability of this invention.

[0012] When adjusting the relative phase angle between oscillator one and oscillator two, the drive motor must first be stopped. Then, the nut is rotated using a wrench, causing the locking cylinder to rotate and retract away from the protective cover within the threaded hole. This loosens the abutting relationship between friction plates one and two, eventually causing them to separate. Therefore, the connecting shaft and the output shaft of the drive motor can rotate relative to each other around the axis of the connecting shaft. At this point, each of the oscillators one and two at both ends of the drive motor falls to its lowest potential energy position due to its own gravity. At this position, the relative phase angle between oscillator one and its corresponding oscillator two can be considered zero. Subsequently, as the locking cylinder continues to retract within the threaded hole, the connecting unit will fix the adjusting rod to the connecting shaft. At this point, friction plates one and two separate, so the rotation of oscillator two will not affect the position of oscillator one. Therefore, the adjusting rod can be grasped and rotated around the axis of the connecting shaft. This causes the connecting shaft connected to the adjusting rod to rotate as well. Since the adjusting rod is fixedly connected to both connecting shafts, the rotation angles of the two connecting shafts are the same. Consequently, the rotation angles of the two second eccentric blocks connected to the two connecting shafts are also the same, and the relative phase angles formed between the two second eccentric blocks and their corresponding first eccentric blocks are also the same. Therefore, the consistency of the relative phase angles of the two eccentric block groups after adjustment is ensured, thereby improving the vibration effect provided by the vibratory motor and contributing to improved energy utilization of the equipment.

[0013] Preferably, the connecting unit includes a hexagonal cap disposed on the end of the connecting shaft away from the drive motor, a turntable rotatably mounted on the end face of the nut portion of the locking cylinder, a through hole for the connecting shaft to pass through the center of the turntable, and a hexagonal slot for accommodating the hexagonal cap on the side of the turntable away from the locking cylinder.

[0014] With this setup, when the locking cylinder retracts from the threaded hole away from the drive motor, firstly, the locking cylinder and the push rod will no longer be tightly abutting, and thus the abutting relationship between the connecting shaft and the output shaft of the drive motor will also become loose, allowing them to rotate relative to each other. Subsequently, as the locking cylinder continues to retract, and with the operator manually aligning it by holding the adjusting rod, the hexagonal slot will approach the hexagonal cap and eventually cause the hexagonal cap to fall into the hexagonal slot and engage. At this point, the hexagonal slot and the hexagonal cap will no longer be able to rotate relative to each other around the axis of the connecting shaft, thus the adjusting rod and the connecting shaft are fixedly connected to each other, and the operator can drive the connecting shaft and the vibrator to rotate by rotating the adjusting rod.

[0015] When the locking cylinder is screwed into the threaded hole towards the drive motor, the hexagonal slot separates from the hexagonal cap, thus releasing the fixed connection between the adjusting rod and the connecting shaft, allowing them to rotate relative to each other. The locking cylinder then abuts against the push block and pushes the push block to make the connecting shaft abut against the output shaft. This fixes the relative position of oscillator one and oscillator two, allowing the torque provided by the output shaft to be transmitted to oscillator two.

[0016] Therefore, during the operation of the vibration motor of the present invention, the connecting unit can disconnect the connection between the adjusting rod and the connecting shaft. Thus, the rotation of the connecting shaft will not cause the adjusting rod to rotate, preventing the adjusting rod from interfering with or affecting the movement of the connecting shaft during the operation of the vibration motor, thereby improving the motion stability of the present invention. Simultaneously, it also avoids the safety risks arising from the rotation of the adjusting rod during the operation of the vibration motor.

[0017] Alternatively, the connecting unit can be configured in another way. In this case, the connecting unit includes a hexagonal cap fixedly mounted on the connecting shaft, a friction plate three fixedly mounted on the turntable, and a friction plate four fixedly mounted on the hexagonal cap. The friction plate four is used to abut against the friction plate three.

[0018] With this configuration, when the locking cylinder is removed from the threaded hole, friction plates three and four abut against each other to generate friction. Under this friction, the hexagonal cap and the turntable cannot rotate relative to each other, allowing the connecting shaft to rotate via the adjusting rod. When the locking cylinder is screwed into the threaded hole, friction plates three and four separate, thus separating the turntable and the hexagonal cap. The fixed connection between the adjusting rod and the connecting shaft is released, allowing them to rotate relative to each other.

[0019] Compared to the connection unit technology described above, this configuration has the advantage that operators do not need to manually align the adjusting rod and connecting shaft when connecting the connection unit, thus simplifying the operation. However, since this solution uses a friction connection, and the friction between friction plate three and friction plate four gradually increases, the torque on the locking cylinder will be continuously transmitted to the connecting shaft through friction as they reach the predetermined tightness. Therefore, the connecting shaft may rotate due to the rotation of the locking cylinder during the contact connection between friction plate three and friction plate four. This could cause a change in the orientation of oscillator one, which was originally in a fixed position, and consequently, a deviation between the relative phase angle of oscillator one and oscillator two after final adjustment from the predetermined relative phase angle.

[0020] It is worth noting that when the locking cylinder moves within the threaded hole, the adjusting rod and the turntable will rotate relative to each other, causing the adjusting rod to be subjected to a bending moment at the connection point with the turntable. Therefore, during long-term use of this invention, the adjusting rod may experience fatigue fracture and damage at the connection point with the turntable. To address this, rotating shafts can be fixedly installed at both ends of the adjusting rod, and supports can be fixedly installed on the turntable, with the rotating shafts rotatably mounted within the supports. This achieves a rotatable connection between the adjusting rod and the turntable, thus preventing the connection point from experiencing fatigue damage when the two rotate relative to each other. Consequently, the service life of this invention is extended.

[0021] Preferably, the protective cover has a rectangular cavity and a cylindrical cavity, the rectangular cavity and the cylindrical cavity are connected, the rectangular cavity has a rectangular cross-section, the cylindrical cavity has a circular cross-section, and the rectangular cavity is an inscribed rectangle of the circular cavity; the push block is a rectangular block, and the push block is disposed in the rectangular cavity.

[0022] When the connecting shaft rotates with the output shaft of the drive motor, a portion of the torque will be applied to the push block. At the same time, because the locking cylinder is in close contact with the push block, the locking cylinder will also be subjected to this portion of torque and will tend to rotate. This may cause the locking cylinder to loosen, thereby damaging the tightness of the connection between friction plate one and friction plate two, and ultimately affecting the vibration effect provided by the present invention.

[0023] With this configuration, the rectangular cavity serves as the main moving space for the push block, while the cylindrical cavity provides the movement space for oscillators one and two. When the push block moves within the protective cover, its rectangular shape engages with the rectangular cavity, preventing rotation as it slides within the cover. This also prevents the locking cylinder, which is tightly pressed against the push block, from rotating, thus preventing loosening and ensuring reliable vibration performance, thereby improving the overall reliability of the invention.

[0024] Furthermore, friction plates one and two may wear down and thin during long-term use, requiring the pusher to move an additional distance to ensure the frictional force between them meets the standard. By setting the rectangular cavity cross-section to an inscribed rectangle of a circular cylindrical cavity cross-section, the pusher can partially enter the cylindrical cavity during movement. Thus, when friction plates one and two wear down, the pusher can partially enter the cylindrical cavity to compensate for the required additional distance, ensuring the frictional force between friction plates one and two meets the standard. This ensures a tight connection between the connecting shaft and the output shaft, improving the reliability of the invention.

[0025] Based on this, a connecting groove is provided on the side wall of the rectangular cavity. The connecting groove is arranged along the axial direction of the protective cover, and one end of the connecting groove is connected to the cylindrical cavity.

[0026] The rectangular cavity can be divided into a space away from the drive motor and a space close to the drive motor, with the push block as the boundary. When the push block and the rectangular cavity fit precisely, the influence of torque on the connecting shaft on the push block can be better prevented, thus helping to ensure better reliability of the invention. However, the precise fit between the push block and the rectangular cavity will make it difficult for the gas in the protective cover to flow in the two spaces of the rectangular cavity away from and close to the drive motor, resulting in additional resistance to the push block during movement.

[0027] This design allows the connecting slot to connect the space in the rectangular cavity away from the drive motor, the space in the rectangular cavity near the drive motor, and the cylindrical cavity. Therefore, when the pusher moves within the rectangular cavity, the gas in these three spaces can flow smoothly to each other. This reduces the resistance to the pusher's movement within the protective cover when the pusher and rectangular cavity are precisely fitted, preventing problems caused by pressure differences hindering the pusher's movement. Consequently, a more precise fit design between the pusher and the rectangular cavity can be adopted, thereby improving the reliability of the invention.

[0028] Preferably, a guide portion is provided on the lower side wall of the rectangular cavity. The guide portion is V-shaped. The connecting groove is provided at the bottom end of the guide portion. A mating portion is provided at the lower end of the push block. The mating portion is used to abut against the guide portion.

[0029] With this design, when dust or other impurities from the external environment pass through the gap between the locking cylinder and the connecting shaft and enter the protective cover, they will first enter the space on the side of the rectangular cavity away from the drive motor. At this point, these impurities will fall downwards into the guide section and then along the guide section into the connecting groove. Therefore, impurities will not remain on the mating surfaces of the push block and the rectangular cavity, thus preventing them from intruding into the mating gap between the push block and the rectangular cavity. This helps ensure smooth movement of the push block within the rectangular cavity while maintaining a precise fit. Consequently, a more precise fit design can be adopted between the push block and the rectangular cavity, thereby improving the reliability of the invention.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. By setting up an adjustment device, this invention allows the adjustment rod to be gripped and rotated around the axis of the connecting shaft, causing the two connecting shafts connected to the adjustment rod to also rotate. Since the adjustment rod is fixedly connected to both connecting shafts via connecting units, the rotation angles of the two connecting shafts are the same. Therefore, the relative phase angles formed between the two eccentric blocks and their corresponding first eccentric blocks are also the same. Thus, the consistency of the relative phase angles of the two eccentric block groups after adjustment is ensured, thereby improving the vibration effect provided by the vibratory motor and contributing to improved energy utilization of the equipment.

[0032] 2. By setting up a connecting unit, when adjusting the relative phase angle between vibrator one and vibrator two, the connecting unit can fix the adjusting rod to the connecting shaft, so that the adjusting rod can drive the two connecting shafts to rotate synchronously. During the operation of the vibratory motor, the connecting unit can disconnect the adjusting rod from the connecting shaft, so the rotation of the connecting shaft will not drive the adjusting rod to rotate. Therefore, the adjusting rod will not interfere with or affect the movement of the connecting shaft during the operation of the vibratory motor, which is beneficial to improving the motion stability of the invention. At the same time, it can also avoid the safety risks caused by the rotation of the adjusting rod during the operation of the vibratory motor.

[0033] 3. By setting a rectangular cavity, the push block can cooperate with the rectangular cavity with its own rectangular shape when moving inside the protective cover, so that the push block will not rotate when sliding inside the protective cover. This also prevents the locking cylinder, which is tightly abutting against the push block, from rotating, thereby preventing the locking cylinder from loosening due to the torque applied by the connecting shaft. This helps to ensure that the invention provides a reliable vibration effect and improves the reliability of the invention. Attached Figure Description

[0043] The following description, with the aid of the accompanying drawings listed in the foregoing "Description of Drawings", will clearly illustrate the specific embodiments of the present invention, in order to enable readers to have a more complete and objective understanding of the working principle and corresponding technical effects of the present invention.

[0044] like Figures 1 to 7 The diagram illustrates a first specific embodiment of the present invention. It should be noted beforehand that the rotatable connection between the turntable 5 and the locking cylinder 34 is achieved through the engagement of a locking block on the locking cylinder 34 and a locking groove on the turntable 5. For details, please refer to [link to relevant documentation]. Figure 4 .

[0045] When installing this invention, first remove the fixed outer casing 1, and fix the drive motor 2 inside the fixed outer casing 1. Both ends of the output shaft 21 of the drive motor 2 are provided with a first oscillator 22 and a second oscillator 23. Two protective covers 3 are symmetrically fixed on the fixed outer casing 1, and the two protective covers 3 cover both ends of the output shaft 21 of the drive motor 2. Both ends of the output shaft 21 of the drive motor 2 are provided with adjustment devices, and both adjustment devices are provided with an adjustment rod 4. The adjustment rod 4 is used to synchronously adjust the relative phase angle between the two second oscillators 23 and the corresponding first oscillator 22.

[0046] The adjusting device includes a threaded hole 33 on the protective cover 3, a locking cylinder 34 inside the threaded hole 33, and threads on the outer wall of the locking cylinder 34 for engaging with the threaded hole 33. The locking cylinder 34 has a nut portion 32. A push block 361 is movably installed inside the protective cover 3, abutting against the locking cylinder 34. A bearing 362 is installed inside the push block 361, and a connecting shaft 35 is fixedly installed inside the bearing 362. The second vibrator 23 is fixedly installed on the connecting shaft 35. Near the end of the drive motor 2, the vibrator 22 is fixedly mounted on the output shaft 21 of the drive motor 2; friction plate 24 and friction plate 25 are fixedly mounted on the vibrator 22 and vibrator 23 respectively, and the friction plate 24 and friction plate 25 are used to abut against each other; the adjusting rod 4 is rotatably mounted on the locking cylinder 34, and the connecting shaft 35 and the locking cylinder 34 are provided with a connecting unit. The connecting unit uses the rotation of the locking cylinder 34 to connect or separate the adjusting rod 4 and the connecting shaft 35.

[0047] The connecting unit includes a hexagonal cap 31 located on the end of the connecting shaft 35 away from the drive motor 2. A turntable 5 is rotatably mounted on the end face of the nut portion 32 of the locking cylinder 34. A through hole for the connecting shaft 35 is opened at the center of the turntable 5. A hexagonal slot 51 is opened on the side of the turntable 5 away from the locking cylinder 34. The hexagonal slot 51 is used to accommodate the hexagonal cap 31.

[0048] Furthermore, the protective cover 3 has a rectangular cavity 36 and a cylindrical cavity 37, which are connected. The rectangular cavity 36 has a cross-section that is an inscribed rectangle of the cross-section of the cylindrical cavity 37. The push block 361 is a rectangular block and is disposed within the rectangular cavity 36. A connecting groove 364 is provided on the side wall of the rectangular cavity 36, which is arranged along the axial direction of the protective cover 3. One end of the connecting groove 364 is connected to the cylindrical cavity 37. A guide part 363 is provided on the lower side wall of the rectangular cavity 36. The guide part 363 is V-shaped, and the connecting groove 364 is provided at the bottom end of the guide part 363. A mating part 365 is provided at the lower end of the push block 361, which is used to abut against the guide part 363. A rotating shaft 55 is fixedly installed at both ends of the adjusting rod 4, and a support 54 is fixedly installed on the turntable 5. The rotating shaft 55 is rotatably installed within the support 54.

[0049] When this invention is in operation, the drive motor 2 rotates oscillator 22 and oscillator 23 to generate vibration. When it is necessary to change the relative phase angle between oscillator 22 and oscillator 23, the adjustment device can be unlocked, separating oscillator 22 and oscillator 23 from their fixed state. Then, using the adjustment rod 4 without removing the protective cover 3, the two oscillators 23 are rotated synchronously, thereby changing the phase angle between oscillator 23 and oscillator 22. Afterwards, the adjustment device is relocked, reconnecting oscillator 23 and oscillator 22, thus fixing and maintaining the relative phase angle between them. Therefore, the relative phase angle between oscillator 22 and oscillator 23 can be adjusted without removing the protective cover 3, making the operation simple. Furthermore, through the synchronous adjustment of the adjustment rod 4, the rotation angle of the two oscillators 23 remains equal throughout the adjustment process, ensuring the consistency of the relative phase angle of the two eccentric block groups at both ends of the drive motor 2.

[0050] The specific working principle of the regulating device is as follows:

[0051] When the locking cylinder 34 is screwed into the threaded hole 33, the end of the locking cylinder 34 near the drive motor 2 will abut against and push the push block 361. Consequently, the connecting shaft 35, coaxially arranged with the output shaft 21 of the drive motor 2, will also be pushed and eventually pressed against the output shaft 21 of the drive motor 2. At this time, friction plates 1 24 and 25 also abut tightly. Under the action of friction, the connecting shaft 35 and the output shaft 21 of the drive motor 2 can no longer rotate relative to each other around the axis of the connecting shaft 35. Therefore, the torque output by the drive motor 2 can be transmitted to the vibrator 23. At this time, the connection unit releases the connection between the adjusting rod 4 and the connecting shaft 35 as the locking cylinder 34 moves within the threaded hole 33. Therefore, the rotation of the connecting shaft 35 will not cause the adjusting rod 4 to rotate, thus preventing the adjusting rod 4 from interfering with or affecting the movement of the connecting shaft 35 during the operation of the vibration motor, which is beneficial to improving the motion stability of the invention.

[0052] When adjusting the relative phase angle between oscillator 23 and oscillator 22, the drive motor 2 must first be stopped. Then, the nut 32 is rotated using a wrench, causing the locking cylinder 34 to rotate and retract away from the protective cover 3 within the threaded hole 33. This loosens the abutting relationship between friction plates 24 and 25, allowing them to eventually separate. Consequently, the connecting shaft 35 and the output shaft 21 of the drive motor 2 can rotate relative to each other around the axis of the connecting shaft 35. At this point, each oscillator 22 and 23 at both ends of the drive motor 2 falls to its lowest potential energy position due to its own gravity. In this position, the relative phase angle between oscillator 22 and its corresponding oscillator 23 can be considered zero. Subsequently, as the locking cylinder 34 continues to retract within the threaded hole 33, the connecting unit will fix the adjusting rod 4 to the connecting shaft 35. At this point, friction plates 24 and 25 separate, and the rotation of oscillator 23 will not affect the position of oscillator 22. Therefore, the adjusting rod 4 can be grasped and rotated around the axis of the connecting shaft 35. The connecting shaft 35, connected to the adjusting rod 4, will also rotate. Since the adjusting rod 4 is fixedly connected to both connecting shafts 35, the rotation angles of the two connecting shafts 35 are the same. Consequently, the rotation angles of the two vibrators 23 connected to the two connecting shafts 35 are the same, and the relative phase angles formed between the two vibrators 23 and their corresponding vibrators 22 are also the same. Therefore, the consistency of the relative phase angles of the two eccentric block groups after adjustment is ensured, thereby improving the vibration effect provided by the vibrating motor and contributing to improving the energy utilization rate of this equipment.

[0053] The connecting unit operates as follows: when the locking cylinder 34 retracts from the threaded hole 33 away from the drive motor 2, the locking cylinder 34 and the push rod will no longer be tightly abutted. Consequently, the abutting relationship between the connecting shaft 35 and the output shaft 21 of the drive motor 2 will also become loose, allowing them to rotate relative to each other. Subsequently, as the locking cylinder 34 continues to retract, and with the operator manually aligning it by holding the adjusting rod 4, the hexagonal slot 51 will approach the hexagonal cap 31 and eventually cause the hexagonal cap 31 to fall into the hexagonal slot 51 and engage. At this point, the hexagonal slot 51 and the hexagonal cap 31 will no longer be able to rotate relative to each other around the axis of the connecting shaft 35. Thus, the adjusting rod 4 and the connecting shaft 35 are fixedly connected to each other, and the operator can drive the connecting shaft 35 and the second vibrator 23 to rotate by rotating the adjusting rod 4.

[0054] When the locking cylinder 34 is screwed into the threaded hole 33 towards the drive motor 2, the hexagonal slot 51 separates from the hexagonal cap 31, thus releasing the fixed connection between the adjusting rod 4 and the connecting shaft 35, allowing them to rotate relative to each other. Subsequently, the locking cylinder 34 abuts against the push block 361 and pushes the push block 361 so that the connecting shaft 35 abuts against the output shaft 21. This fixes the relative position of the first oscillator 22 and the second oscillator 23, and the torque provided by the output shaft 21 can be transmitted to the second oscillator 23.

[0055] It is worth noting that, regarding the rectangular cavity 36 and the cylindrical cavity 37, the rectangular cavity 36 is the main moving space for the push block 361, while the cylindrical cavity 37 is the moving space for the first oscillator 22 and the second oscillator 23. When the push block 361 moves within the protective cover 3, its rectangular shape allows it to engage with the rectangular cavity 36, preventing rotation during sliding within the protective cover 3. This also prevents the locking cylinder 34, which is tightly abutted against the push block 361, from rotating, thus preventing loosening and ensuring the reliable vibration effect provided by the invention, thereby improving the reliability of the invention.

[0056] Furthermore, friction plates 24 and 25 may wear down and thin during long-term use, requiring push block 361 to move an additional distance to ensure adequate friction between them. By designing the rectangular cavity 36 to be an inscribed rectangle of the circular cross-section of the cylindrical cavity 37, push block 361 can partially enter the cylindrical cavity 37 during movement. Thus, when friction plates 24 and 25 wear down, push block 361 can partially enter the cylindrical cavity 37 to compensate for the additional travel, ensuring adequate friction between friction plates 24 and 25. This ensures a tight connection between connecting shaft 35 and output shaft 21, improving the reliability of the invention.

[0057] Another point worth noting is that the rectangular cavity 36 can be divided into a space away from the drive motor 2 and a space close to the drive motor 2, with the push block 361 as the boundary. When the push block 361 and the rectangular cavity 36 are precisely fitted, the influence of the torque on the connecting shaft 35 on the push block 361 can be better prevented, thus helping to ensure better reliability of the invention. However, the precise fit between the push block 361 and the rectangular cavity 36 will make it difficult for the gas in the protective cover 3 to flow in the two spaces of the rectangular cavity 36 that are away from and close to the drive motor 2, resulting in additional resistance to the movement of the push block 361.

[0058] To this end, a connecting groove 364 is provided, which connects the space of the rectangular cavity 36 away from the drive motor 2, the space of the rectangular cavity 36 near the drive motor 2, and the cylindrical cavity 37. Thus, when the push block 361 moves within the rectangular cavity 36, the gas in these three spaces can flow smoothly to each other. This reduces the resistance to the push block 361's movement within the protective cover 3 when the push block 361 and the rectangular cavity 36 are precisely fitted, avoiding the problem of the push block 361's movement being obstructed due to pressure differences. Therefore, a more precise fit design can be adopted between the push block 361 and the rectangular cavity 36, thereby improving the reliability of the invention.

[0059] like Figure 8 The diagram illustrates a second specific embodiment of the present invention. The difference between this embodiment and the first embodiment lies in the connecting unit. Specifically, the connecting unit includes a hexagonal cap 31 fixedly mounted on the connecting shaft 35, a friction plate three 52 fixedly mounted on the turntable 5, and a friction plate four 53 fixedly mounted on the hexagonal cap 31. The friction plate four 53 is used to abut against the friction plate three 52.

[0060] In this embodiment, when the locking cylinder 34 is withdrawn from the threaded hole 33, friction plates 3 and 4 can abut against each other to generate friction. Under the action of friction, the hexagonal cap 31 and the turntable 5 cannot rotate relative to each other, so the connecting shaft 35 can be rotated by the adjusting rod 4. When the locking cylinder 34 is screwed into the threaded hole 33, friction plates 3 and 4 separate, and the turntable 5 and the hexagonal cap 31 separate. The fixed connection between the adjusting rod 4 and the connecting shaft 35 is released, and the adjusting rod 4 and the connecting shaft 35 can rotate relative to each other.

[0061] Compared with the first embodiment, this embodiment has the advantage that the operator does not need to manually align the adjusting rod 4 and the connecting shaft 35 when connecting the connecting unit, thus simplifying the operation steps. However, since this solution uses a friction connection, and the friction between friction plate three 52 and friction plate four 53 gradually increases, the torque on the locking cylinder 34 will be continuously transmitted to the connecting shaft 35 through friction as they reach the predetermined tightness of the fit. Therefore, the connecting shaft 35 may rotate due to the rotation of the locking cylinder 34 during the contact connection between friction plate three 52 and friction plate four 53, which may cause the position of the oscillator one 22, which was originally in a fixed position, to change. Consequently, the relative phase angle between oscillator one 22 and oscillator two 23 may deviate from the predetermined relative phase angle after the final adjustment.

[0062] It should be emphasized that, based on the content described above, although the beneficial effects of the present invention have been explained in detail and corresponding specific embodiments have been provided, those skilled in the art can still achieve the same technical effects by making conventional substitutions, modifications, or other alterations to the given technical solutions without creative effort, provided they fully understand the working principle of the present invention. However, such modifications should not be considered as exceeding the scope of the present invention. Specifically, the scope of the present invention is defined by the appended claims and their equivalents.
