Description

Technical Field

[0001] This invention relates to the field of oscillation device technology, and more particularly to a medical testing oscillation device. Background Technology

[0002] In medical testing laboratories, shaking devices are crucial equipment for mixing samples and reagents, accelerating reactions, or preventing precipitation. Currently, common shaking devices on the market, such as vortex shakers, horizontal shakers, and rotary mixers, typically have a single and fixed motion pattern. This functional limitation of existing medical testing shaking devices has become a key bottleneck restricting laboratory automation and efficiency improvements. Current equipment often employs fixed frequencies and single motion trajectories; for example, it may be a circular vortex around a vertical axis, a reciprocating linear motion in a horizontal plane, or a rotary motion around a horizontal axis. Driven by horizontal reciprocating, circular rotation, or vortex designs, a single instrument can usually only optimize a specific testing step. For example, the gentle oscillation required for blood routine mixing, the vigorous three-dimensional vortex mixing required for nucleic acid extraction, and the low-frequency micro-amplitude perturbation required for immune incubation all require different specialized equipment. This "one machine, one mode" approach not only occupies valuable laboratory bench space and increases purchase costs but also forces operators to manually transfer samples between multiple devices, reducing work efficiency and introducing the risk of errors and contamination during the transfer process.

[0003] The aforementioned limitations stem from the inherent lack of adaptability in the mechanical structures of existing technologies. Their core drive components are rigidly designed to generate a fixed periodic motion, unable to adapt to the physical characteristics of the sample or the needs of different reaction stages during operation. This prevents the implementation of complex composite motions, such as superimposing linear reciprocating motion on circular oscillations or dynamically changing the tilt angle of the oscillation plane. Therefore, to address these issues, we propose a medical testing oscillation device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a medical testing oscillation device.

The electric telescopic rod, the adjusting screw, and the dual-axis motor are on the same straight line. The telescopic end of the electric telescopic rod faces downward and is fixed to a horizontal block by a support block. A slider is slidably provided on the horizontal block. The two sides of the slider are fixedly connected to the horizontal block by a first spring. A positioning block is slidably provided on the top of the slider. The positioning block and the slider are fixedly connected by a second spring. The top of the positioning block is arc-shaped. The lower side of the inner ring block is provided with an arc-shaped groove that fits and matches the positioning block.

[0010] Preferably, the lateral pushing mechanism includes a sliding shell fixed to the bottom of a rectangular base plate. The sliding shell is slidably installed in a rectangular cavity. One output end of the dual-axis motor passes through the rectangular base plate and is coaxially fixedly connected to a driving bevel gear. A driven bevel gear is rotatably connected inside the sliding shell. The driving bevel gear and the driven bevel gear mesh and match. A push rod is horizontally slidably installed at the bottom of the rectangular base plate. The push rod is connected to the driven bevel gear through a second connecting rod. One end of the second connecting rod is rotatably connected to the side of the driven bevel gear away from the center, and the other end of the second connecting rod is rotatably connected to one end of the push rod.

The soft foam pad has several placement holes that are aligned with several mounting holes. The bottom of the test tube body is used to insert into the placement hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up an adjustable tilt oscillation mechanism consisting of an outer ring block, an inner ring block, and an adjusting block, in conjunction with an adjusting screw and a first connecting rod, allows the operator to steplessly adjust the tilt angle of the oscillation platform before oscillation. This enables the simulation of a tilted state by changing the tilt angle, achieving both horizontal and tilted oscillation operations. This provides a foundation for generating more complex composite oscillation trajectories and significantly improves the versatility and adaptability of the equipment.

[0016] 2. By setting a dual-axis motor as the core power source, the present invention synchronously drives the upper circular oscillation mechanism and the lower transverse reciprocating mechanism, realizing the organic combination and linkage of two basic motions of the oscillation platform in the horizontal plane: circular swaying and linear reciprocating. This purely mechanical linkage design can produce a complex mixing effect similar to a three-dimensional vortex without the need for a complex control system. The mixing efficiency is higher, and the structure is reliable and the cost is controllable.

[0017] 3. This invention, by setting up a positioning mechanism with automatic reset and positioning functions, controls the lifting and lowering of the positioning block through an electric telescopic rod, and combines an inner ring block with an arc groove, as well as a flexible alignment and buffer structure composed of a first spring and a second spring. This mechanism can not only lock the oscillation platform in a preset initial position for safe handling and equipment initialization, but also guide and lock the inner ring block after oscillation ends, ensuring that the equipment returns to the determined initial position after each stop, thus improving the repeatability and convenience of operation.

[0018] 4. By designing a detachable connection between the push rod and the rectangular cavity, and configuring a buffer spring, this invention allows users to flexibly choose whether to enable lateral reciprocating motion according to experimental needs, thereby quickly switching between simple circular oscillation and compound oscillation modes. At the same time, the test tube placement mechanism can provide necessary elastic buffering to prevent the test tube from breaking during violent oscillation, and allow the test tube to have a certain adaptive shaking space to improve the mixing effect.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Reference Figure 1 - Figure 10 A medical testing vibration device includes a rectangular base plate 1 and a parallel vibration platform 2. Four main springs 3 are vertically fixed at the four corners of the rectangular base plate 1, and the tops of the four main springs 3 are fixedly connected to the bottom of the vibration platform 2. This structure constitutes a suspension support system capable of multi-directional elastic movement. An adjustable-angle vibration mechanism is matched between the rectangular base plate 1 and the vibration platform 2. A drive mechanism for driving the vibration mechanism is provided on the rectangular base plate 1, and a lateral pushing mechanism is also linked to the bottom of the rectangular base plate 1. The four main springs 3, the vibration mechanism, and the drive mechanism are all disposed between the rectangular base plate 1 and the vibration platform 2. A housing 4 is matched between the rectangular base plate 1 and the vibration platform 2, serving to house and protect the internal mechanisms. The lateral pushing mechanism is used to move the housing 4, the rectangular base plate 1, and all components on both. A test tube placement mechanism matched with the vibration platform 2 is provided on the housing 4.

[0024] The oscillation mechanism includes a rotating seat 5 fixedly mounted between four main springs 3. The rotating seat 5 is fixed to a rectangular base plate 1. An outer ring block 6 is located at the top of the rotating seat 5, and in its normal state, the outer ring block 6 is vertically oriented. The outer side of the outer ring block 6 is rotatably connected to the rotating seat 5 via a shaft or bearing, allowing the outer ring block 6 to pitch around a horizontal axis on the rotating seat 5. An inner ring block 7 is coaxially rotatably connected to the inner ring block 6, for example, via a pair of concentric bearings, allowing the inner ring block 7 to rotate relative to the outer ring block 6 around their common axis. An adjusting block 8 is connected to the inner side of the inner ring block 7, for example, by welding or bolting. A smooth rod 9 is vertically fixed to the center of the adjusting block 8. A connecting post 10 is slidably fitted onto the smooth rod 9. The connecting post 10 has a smooth hole or linear bearing that matches the smooth rod 9, allowing the smooth rod 9 to slide up and down and rotate within the connecting post 10. The top of the connecting post 10 is fixedly connected to the bottom of the oscillation platform 2, thereby transmitting the movement of the adjusting block 8 to the oscillation platform 2. The guide rod 9 can transfer kinetic energy to the connecting column 10, which in turn transfers it to the oscillation platform 2, thus achieving the subsequent oscillation effect on the oscillation platform 2. The adjusting block 8 can rotate. When it rotates, the adjusting block 8 drives the guide rod 9, which in turn drives the connecting column 10, thereby driving the oscillation platform 2. The four main springs 3 support the oscillation platform 2 and facilitate its vibration. Furthermore, the rotation of the adjusting block 8 can drive the inner ring block 7 to rotate along the axis of the outer ring block 6. That is, when the axis of the outer ring block 6 is vertical, the inner ring block 7 drives the adjusting block 8 to rotate in the horizontal plane.

[0025] To achieve adjustable tilt angle of the oscillation platform 2, the housing 4 is equipped with an adjustment mechanism for rotating and adjusting the outer ring block 6. The adjustment mechanism includes a horizontally positioned adjusting screw 11. One end of the adjusting screw 11 is threaded through the side wall of the housing 4 and is rotatably connected to a connecting block 12 via a threaded engagement. This rotatable connection allows the connecting block 12 to move with the adjusting screw 11 but not to rotate with it. The connecting block 12 is connected to the outer ring block 6 via a first connecting rod 13. Both ends of the first connecting rod 13 are rotatably connected to the connecting block 12 and the hinge seats on the outer side of the outer ring block 6, respectively. The first connecting rod 13 is inclined. The outer ring block 6 and the first connecting rod 13 can react on the adjusting screw 11, stabilizing its orientation. One end of the adjusting screw 11 extends out of the housing 4 and is fixed with a rotating block or handwheel. The adjusting screw 11 can be rotated by the rotating block, and the rotation of the adjusting screw 11 achieves the effect of threaded advancement. This, in turn, pushes or pulls the first connecting rod 13 through the connecting block 12. The first connecting rod 13 is compressed or stretched, changing its original state and acting on the outer ring block 6. This causes the outer ring block 6 to tilt around the axis connected to the rotating seat 5. That is, the outer ring block 6 rotates on the rotating seat 5. After the outer ring block 6 tilts, it can drive the inner ring block 7 and the corresponding adjusting block 8 to tilt. The adjusting block 8 then drives the connecting column 10 through the smooth rod 9, ultimately causing the oscillation platform 2 to tilt and adjust. In subsequent vibration operation of the oscillation platform 2, the oscillation platform 2 can be tilted before vibration operation, effectively improving the flexibility of vibration and achieving more complex oscillation effects.

[0026] The drive mechanism includes a dual-axis motor 14, whose power supply and control lines can be arranged inside the housing 4 and connected to an external power source and a simple controller. It has two coaxial output shafts. One output end of the dual-axis motor 14 faces upward and is coaxially fixedly connected to a rotating column 15. One end of the adjusting block 8 is provided with a bearing and is rotatably connected to the upper end of the rotating column 15, allowing the adjusting block 8 to rotate freely on the rotating column 15. Simultaneously, the rotation of the rotating column 15 drives the adjusting block 8 to revolve around its axis. The dual-axis motor 14 is fixedly connected to the rectangular base plate 1 via a bracket. The start of the dual-axis motor 14 controls the rotation of the rotating column 15, thereby controlling the adjustment block 8 to rotate around the axis of the dual-axis motor 14. Since the guide rod 9 is fixedly connected to the middle of the adjusting block 8, and one end of the adjusting block 8 is rotatably connected to the rotating column 15, when the rotating column 15 rotates and drives the adjusting block 8 to rotate, the guide rod 9 is in an eccentric rotation. At this time, the guide rod 9 acts on the connecting column 10, which drives the oscillating platform 2 to oscillate in a circular motion around the rotating axis of the dual-axis motor 14. The four main springs 3 can swing with the oscillation platform 2, satisfying the support of the oscillation platform 2 without affecting the tilt adjustment and oscillation operation of the oscillation platform 2.

[0027] To lock the moving parts when the equipment is not in operation or when a fixed tilt angle is required, the outer ring block 6 is provided with a positioning mechanism on its side for positioning the inner ring block 7. The positioning mechanism includes an electric telescopic rod 16 vertically fixed to the outside of the outer ring block 6. Its power supply and control lines can be arranged inside the housing 4 and connected to an external power supply and a simple controller. The controller can be equipped with "positioning" and "release" buttons. The electric telescopic rod 16, the adjusting screw 11, and the dual-axis motor 14 are located on the same straight line. That is, when the arc groove 22 on the inner ring block 7 rotates to be aligned with the straight line, the positioning block 20 can fall into the groove. The telescopic end of the electric telescopic rod 16 faces downward and is fixed by a support block. A horizontal block 17 is provided, on which a slider 18 is slidably mounted. This horizontal sliding is achieved, for example, via a guide rail or groove. The two sides of the slider 18 are fixedly connected to the horizontal block 17 by first springs 19, giving the slider 18 a tendency to automatically reset in the horizontal direction. A positioning block 20 is slidably mounted on the top of the slider 18, for example, via a guide post and guide sleeve structure. The positioning block 20 is fixedly connected to the slider 18 by a second spring 21, giving the positioning block 20 a tendency to pop upwards in the vertical direction. The top of the positioning block 20 is arc-shaped, facilitating its sliding into an arc-shaped groove 22. The lower side of the inner ring block 7 has an arc-shaped groove 22 that fits and matches the positioning block 20. The telescopic end of the electric telescopic rod 16 can drive the horizontal block 17 and its related components to move up and down as a whole. After the positioning block 20 is inserted into the arc-shaped groove 22, it can position the inner ring block 7, preventing the inner ring block 7 from rotating. This also ensures that the electric telescopic rod 16, the adjusting screw 11, the dual-axis motor 14, and the adjusting block 8 are on the same straight line, allowing for convenient tilt adjustment of the adjusting block 8. Similarly, the electric telescopic rod 16 can disengage the positioning block 20 from the arc-shaped groove 22. When the positioning block 20 needs to be inserted into the arc-shaped groove 22, it can first be controlled to rest against the lower side of the inner ring block 7. At this time, the second spring 21 is compressed and contracts. As the dual-axis motor 14 slowly drives the inner ring block 7 to rotate, the positioning block 20 moves to the position of the arc-shaped groove 22. Then, under the lifting action of the second spring 21, the positioning block 20 is pushed into the arc-shaped groove 22, achieving the positioning operation. If the inner ring block 7 still moves slightly, pushing the positioning block 20 will push the slider 18 to compress the first spring 19 on one side. The first spring 19 provides a buffering effect. Furthermore, a magnetic tactile switch, such as a reed switch and a magnet (not shown in the figure), can be installed on the top of the positioning block 20 or inside the arc-shaped groove 22. This switch can sense the movement within the arc-shaped groove 22 and, upon sensing, provide feedback to the controller of the dual-axis motor 14, thereby stopping the dual-axis motor 14. During this process, after the dual-axis motor 14 stops, the two first springs 19 ultimately position the slider 18 in the middle, thus ensuring that the positioning block 20 positions the electric telescopic rod 16, the adjusting screw 11, the dual-axis motor 14, and the adjusting block 8 onto the same straight line, achieving a reset effect.After the positioning block 20 is inserted into the arc-shaped groove 22, it can effectively restrict the rotation of the inner ring block 7, that is, restrict the positioning oscillation platform 2, which facilitates the stable handling of this device.

[0028] The lateral pushing mechanism includes a sliding shell 23 fixed to the bottom of a rectangular base plate 1. The sliding shell 23 is slidably installed within a rectangular cavity 24. The rectangular cavity 24 can be considered part of the equipment base or worktable surface; that is, the rectangular cavity 24 has an open-top cavity, and the sliding shell 23 is slidably installed within the cavity. A driving bevel gear 25 is coaxially fixedly connected to the lower output end of the dual-axis motor 14, passing through the rectangular base plate 1. A driven bevel gear 26 is rotatably connected inside the sliding shell 23 via bearings, and its axis is perpendicular to the axis of the driving bevel gear 25. (Refer to...) Figure 5 The driving bevel gear 25 meshes with the driven bevel gear 26, and this meshing relationship is maintained by the tooth width of the gears regardless of how the sliding housing 23 slides laterally. A push rod 27 is horizontally mounted on the bottom of the rectangular base plate 1 via a slide rail or groove. The push rod 27 is connected to the driven bevel gear 26 via a second connecting rod 28. One end of the second connecting rod 28 is rotatably connected to an eccentric hinge point on the side of the driven bevel gear 26 away from the center, and the other end of the second connecting rod 28 is rotatably connected to one end of the push rod 27. The other end of the push rod 27 is detachably fixed to the inner side of the rectangular cavity 24. For example, when compound oscillation is required, a detachable fixed connection can be achieved by a vertical pin or bolt, for example, the bolt thread passes through a fixing lug on the side wall of the rectangular cavity 24 and is fixedly connected to the threaded hole at the end of the push rod 27. When the dual-axis motor 14 starts, it can drive the active bevel gear 25 to rotate, which in turn drives the driven bevel gear 26 to rotate. The driven bevel gear 26 then acts as a crank to drive the second connecting rod 28, which in turn enables the push rod 27 to reciprocate, similar to a piston reciprocating mechanism.

[0029] Multiple buffer springs 29 are fixed to the side of the sliding shell 23 opposite to the push rod 27, and all the buffer springs 29 are fixedly connected to the inner side of the rectangular cavity 24. The reciprocating movement of the push rod 27 can push or pull the sliding shell 23 to reciprocate, which can drive the shell 4 to reciprocate as a whole. The multiple buffer springs 29 play a role in buffering and assisting in resetting. The reciprocating movement of the shell 4 can realize the reciprocating movement of the oscillation platform 2 in another direction through the transmission of the main spring 3, further realizing the multi-directional oscillation effect.

[0030] When the push rod 27 is fixedly connected to the rectangular cavity 24, the buffer spring 29 is in a stretched state. When the push rod 27 disengages from the inside of the rectangular cavity 24, i.e., the connecting bolts or pins are removed, the multiple buffer springs 29 can pull or push the housing 4 to one side of the rectangular cavity 24, so that the end of the push rod 27 no longer contacts the rectangular cavity 24. Even if the push rod 27 is extended to its maximum length, it will not contact the rectangular cavity 24. At this time, the reciprocating movement of the push rod 27 will not have a reaction effect on the housing 4, that is, the housing 4 will not reciprocate. At this time, the oscillation platform 2 can perform a simple circular oscillation operation without lateral reciprocating movement.

[0031] The top of the housing 4 has an opening, and there is a gap between the opening and the oscillation platform 2. The opening allows the oscillation platform 2 to move in multiple degrees of freedom, and the gap is covered with a rubber sleeve 30 or a corrugated pipe. The rubber sleeve 30 serves to prevent dust, prevent liquid splashing, and provide safety protection. Its flexibility allows the oscillation platform 2 to perform normal oscillation operation.

[0032] The test tube placement mechanism includes a soft foam pad 31 detachably and fixedly connected to the top of the vibration platform 2. This soft foam pad 31 possesses a certain degree of elasticity and friction. A hard plastic plate is fixedly connected to the bottom of the soft foam pad 31, and the hard plastic plate is fixedly connected to the top of the vibration platform 2 by screws or by locking pins. A mounting tray 33 is parallel to the soft foam pad 31. Four telescopic columns 32 are vertically fixed around the perimeter of the housing 4. These columns have a sleeve-type structure, and the telescopic ends of the telescopic columns 32 can be fixed in position by fastening knobs. Specifically, a fastening knob is threaded through the top side of the telescopic column 32, and the fastening knob abuts against the side of the telescopic end of the telescopic column 32, thereby achieving the effect of squeezing and fixing the telescopic end. The mounting tray 33 can be detachably and fixedly connected to the top of the four telescopic columns 32, for example, by quickly engaging the slots at the four corners of the tray with the locking blocks at the top of the telescopic columns, or by fixing with screws. The mounting tray 33 can also be detachably and fixedly connected to the top of the four telescopic columns 32 by screws via four brackets. The mounting tray 33 has several mounting holes, and a test tube positioning mechanism is installed in each mounting hole.

[0033] The test tube positioning mechanism includes a fixing block 34, which has a through hole for the test tube body 35 to pass through. A positioning bolt 36 is threaded through the side of the through hole and can be pressed against the side of the test tube body 35 to achieve a tight fit. Four connecting springs 37 are fixedly fixed around the fixing block 34 at equal intervals, and the four connecting springs 37 are respectively fixedly connected to the inner wall of the mounting hole, thereby elastically suspending the fixing block 34 in the center of the mounting hole. The soft foam pad 31 has several placement holes aligned with several mounting holes, and its diameter is slightly larger than the bottom of the test tube. The bottom of the test tube body 35 is used to insert into the placement holes. When placing the test tube body 35, it is first inserted into the through hole of the fixing block 34, with its bottom inserted into the corresponding placement hole. Then, the positioning bolt 36 is rotated to abut against the side of the test tube body 35, achieving the effect of abutting and fixing the test tube body 35. Subsequently, when the oscillation platform 2 shakes circumferentially, the hardness of the soft foam pad 31 allows it to push and drive the test tube body 35 to shake along with it, and the soft foam pad 31 also serves to cushion and protect the bottom of the test tube body 35 during shaking. At the same time, since the fixing block 34 is connected to the mounting tray 33 through the connecting spring 37, the test tube body 35 can achieve the required small-amplitude adaptive shaking in the early stage of oscillation without being rigidly constrained by the mounting tray 33.

[0034] It should be noted that this application is not limited to the test tube body 35; other containers, such as beakers, can also be placed on it, and the fixing blocks 34 and soft foam pads 31 on the mounting tray 33 will be adapted accordingly. Furthermore, the number of mounting holes and placement holes corresponding to the mounting tray 33 and soft foam pads 31 can be set according to requirements.

[0035] The working principle and control logic of this invention are briefly described below: When using this invention, first place the corresponding test tube body 35 containing the liquid to be shaken. When placing it, first insert the bottom of the test tube body 35 into the through hole of the fixing block 34 until its bottom is inserted into the corresponding placement hole. Then, use the corresponding positioning bolt 36 to rotate and abut against the side of the test tube body 35 to achieve the effect of abutting and fixing the test tube body 35.

[0036] Single-direction circular oscillation mode: Ensure push rod 27 is disengaged from rectangular cavity 24. Adjust oscillation platform 2 to the desired tilt angle, including a horizontal position, by rotating adjusting screw 11. Start dual-axis motor 14 to perform circular oscillation in a single direction.

[0037] Composite oscillation mode: The push rod 27 is fixed to the rectangular cavity 24 with bolts. Starting the dual-axis motor 14 enables a composite motion of circular oscillation and transverse reciprocating oscillation.

[0038] Single horizontal reciprocating mode: In the compound oscillation mode, the tilt angle of the oscillation platform 2 is adjusted to be horizontal, and the speed of the dual-axis motor 14 is appropriately reduced. At this time, the equipment mainly moves in horizontal reciprocating motion.

[0039] During the oscillation operation, the dual-axis motor 14 is started, which controls the rotation of the rotating column 15, thereby controlling the rotation of the adjusting block 8. Since the guide rod 9 is fixedly connected to the middle of the adjusting block 8, and one end of the adjusting block 8 is rotatably connected to the rotating column 15, the guide rod 9 rotates eccentrically when the rotating column 15 drives the adjusting block 8 to rotate. At this time, the guide rod 9 acts on the connecting column 10, which drives the oscillation platform 2 to oscillate in a circle around the rotating shaft of the dual-axis motor 14. When the oscillation platform 2 oscillates in a circle, the hardness of the soft foam pad 31 allows it to push and drive the test tube body 35 to oscillate along with it, and the soft foam pad 31 also serves to cushion and protect the test tube body 35 during oscillation.

[0040] When the dual-axis motor 14 starts, it can also synchronously drive the active bevel gear 25 to rotate. The active bevel gear 25 drives the driven bevel gear 26 to rotate, and the driven bevel gear 26 drives the second connecting rod 28. The second connecting rod 28 realizes the reciprocating motion of the push rod 27. The reciprocating movement of the push rod 27 can push the sliding shell 23 to move back and forth, which can drive the shell 4 to move back and forth as a whole. Multiple buffer springs 29 play a buffering role. The reciprocating movement of the shell 4 can realize the reciprocating movement of the oscillation platform 2 in another direction through the rectangular base plate 1 and the main spring 3, further realizing the multi-directional oscillation effect.

[0041] In the above operation, if the tilt angle needs to be adjusted before the oscillation operation, ensure that the positioning block 20 is disengaged from the arc groove 22 by controlling the retraction of the electric telescopic rod 16. At this time, the inner ring block 7 can rotate freely, and the outer ring block 6 can be adjusted. Then, by rotating the adjusting screw 11, the first adjusting link 13 is pushed. The first link 13 is compressed and acts on the outer ring block 6, causing the outer ring block 6 to tilt. That is, the outer ring block 6 rotates on the rotating seat 5. After the outer ring block 6 tilts, it can drive the inner ring block 7 and the corresponding adjusting block 8 to tilt. The adjusting block 8 then drives the connecting column 10 through the smooth rod 9, ultimately driving the oscillation platform 2 to tilt and adjust. In the subsequent vibration operation of the oscillation platform 2, the oscillation platform 2 can achieve tilt adjustment before vibration operation, effectively improving the flexibility of vibration and achieving rich oscillation effects.

[0042] After the oscillation ends, if it is necessary to move or fix the equipment, the dual-axis motor 14 can be stopped first. Then, the electric telescopic rod 16 is started to extend, allowing the top of the positioning block 20 to contact and be pressed against the lower surface of the inner ring block 7. The dual-axis motor 14 is then started in a low-speed jog mode to drive the inner ring block 7 to rotate slowly. When the inner ring block 7 rotates to the point where the arc groove 22 is aligned with the positioning block 20, the positioning block 20 will insert into the arc groove 22 under the action of the second spring 21, and a sound will be emitted. If a sensor switch is provided, the dual-axis motor 14 will stop automatically; if not, the operator will manually stop the machine after observing the positioning block 20 spring in or hearing the sound. At this time, the inner ring block 7 and its connected adjusting block 8 and oscillation platform 2 are all locked in the initial position. The balancing effect of the two first springs 19 ensures that the axes of the positioning block 20 and the electric telescopic rod 16 are aligned, that is, the positioning block 20 once again positions the electric telescopic rod 16, the adjusting screw 11, the dual-axis motor 14, and the adjusting block 8 on the same straight line, achieving a reset effect. After the positioning block 20 is inserted into the arc-shaped groove 22, it can effectively restrict the rotation of the inner ring block 7, that is, restrict the positioning oscillation platform 2, which facilitates the stable handling of this device.

[0043] The four connecting springs 37 corresponding to the test tube body 35 in the above operation enable the test tube body 35 to achieve the required small-amplitude self-adjusting shaking in the early stage of oscillation, without being subject to rigid constraints.

[0044] In the above operation, the four main springs 3 can swing with the oscillation platform 2 in multiple degrees of freedom, satisfying the support of the oscillation platform 2 while not affecting the tilt adjustment and swaying oscillation operation of the oscillation platform 2.

[0045] In the above operation, the buffer spring 29 is in a stretched state when the push rod 27 is fixedly connected to the rectangular cavity 24. When the push rod 27 disengages from the inside of the rectangular cavity 24, the multiple buffer springs 29 can pull the housing 4 as a whole to one side of the rectangular cavity 24, so that the push rod 27 no longer contacts the rectangular cavity 24. Even if the push rod 27 is extended to its maximum length, it will not contact the rectangular cavity 24. At this time, the reciprocating movement of the push rod 27 will not have a reaction effect on the housing 4, that is, the housing 4 will not reciprocate. At this time, the oscillation platform 2 can perform oscillation operation without reciprocating movement.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
