Specifically, the holder 41 includes a plurality of vertical rods 411 distributed around the circumferential direction of the base 10 and a horizontal frame 412 connecting the plurality of vertical rods 411 together, the bottom of the vertical rod 411 is inserted into the slot 11 on the base 10, so as to be fixedly connected with the base 10, and the horizontal frame 412 is sleeved outside the plurality of vertical rods 411 at the same time, so as to improve the stability of the holder 41 as a whole.

When the retaining ring 42 is used, the retaining ring 42 is sleeved outside the tubular container 30, and the retaining ring 42 is connected with the retaining frame 41 through a plurality of first elastic connecting structures distributed along the circumferential direction of the retaining ring 42, so that the retaining ring 42 is suspended. The inner diameter of the retaining ring 42 is slightly larger than the outer diameter of the tubular container 30, and when the outer diameter of the tubular container 30 is adjusted, the corresponding retaining ring 42 is replaced, in this case, the connecting part of the first elastic connecting structure and the retaining ring 42 is detachable, so that different retaining rings 42 can be replaced conveniently.

The first elastic structure may be a structure including a spring, or may be another structure, for example, a structure preferred in the present embodiment, in which the first elastic structure includes a first elastic cord 431, and one end of the first elastic cord 431 is connected to the retaining ring 42, and the other end is connected to the retainer 41. The one end of the first elastic rope 431 is fixedly connected with a first connecting block 432, a plurality of first clamping grooves 421 are formed in the retaining ring 42, the number of the first clamping grooves 421 is the same as that of the first connecting blocks 432, and the first connecting blocks 432 are inserted into the first clamping grooves 421, so that clamping fit is formed.

The gland 44 is located above the retaining ring 42, the gland 44 being connected to the cage 41 by a plurality of second resilient connecting structures distributed along its circumference and in this way being suspended above the retaining ring 42. The pressing cover 44 serves to press the tubular container 30 downward from the top of the tubular container 30 after the tubular container 30 is placed on the oscillation drive table 20, and the second elastic connection structure provides the pressing cover 44 with a force for pressing the tubular container 30.

The second elastic connection structure may be a structure including a spring, or may be another structure, for example, a structure preferred in the present embodiment, the second elastic connection structure includes a second elastic string 451, one end of the second elastic string 451 is connected to the pressing cover 44, and the other end is connected to the holder 41. The one end of the second elastic string 451 is fixedly connected with a second connection block 452, a plurality of second locking grooves 441 are formed on the pressing cover 44, the number of the second locking grooves 441 is the same as that of the second connection block 452, and the second connection block 452 is inserted into the second locking grooves 441, so that a clamping fit is formed.

In this embodiment, the experimenter passes the tubular container 30 through the retaining ring 42 and places the tubular container 30 on the oscillation drive table 20, and then covers the gland 44 on the top of the tubular container 30, and the oscillation drive table 20 operates to vibrate the tubular container 30 together. The middle upper portion of the tubular container 30 is restrained in the amplitude of the horizontal vibration of the tubular container 30 by the cooperation of the retaining ring 42 and the first elastic connecting structure. The top of the tubular container 30 is under the combined action of the pressing cover 44 and the second elastic connecting structure, so that the tubular container 30 cannot jump in the vertical direction during the vibration process, and the bottom of the tubular container 30 is always located in the groove on the oscillating driving platform 20, thereby avoiding the situation that the tubular container 30 is separated from the oscillating driving platform 20. Through the arrangement of the structure, the experimenter installs the tubular container 30 and does not need to hold the upper part of the tubular container 30 by hands after starting the vortex oscillator, thereby reducing the workload of the experimenter and improving the working efficiency.

In one embodiment, the holder 41 is provided with an elastic force adjusting structure, which includes a plurality of first through holes 51, an adjusting rod 52, a plurality of second through holes 53, pawls 54, and a manual adjusting structure. The first through holes 51 penetrate the vertical rod 411 in the radial direction of the retaining ring 42, and a plurality of first through holes 51 are provided on the vertical rod 411 at intervals in the vertical direction. The adjusting rod 52 can slide in any one of the first through holes 51, that is, the adjusting rod 52 can be inserted into the other first through hole 51 after being pulled out from one first through hole 51, and a row of ratchet teeth 521 is provided on one side of the adjusting rod 52, preferably, the ratchet teeth 521 are provided on one side surface of the adjusting rod 52 in the vertical direction. The second through holes 53 are arranged in one-to-one correspondence with the first through holes 51, specifically, each first through hole 51 is provided with a second through hole 53 communicated with the first through hole 51, a pawl 54 is integrally arranged in each second through hole 53, one end of the pawl 54 is fixedly connected with the hole wall of the second through hole 53, and the other end of the pawl 54 is matched with the ratchet 521, so that a one-way moving structure is formed. The manual adjustment structure is used to separate or engage the pawl 54 and the ratchet 521 with each other. Depending on the size of the tubular container 30, the position of the adjustment lever 52 and thus the height of the retaining ring 42 can be varied to accommodate the size of the tubular container 30.

In one embodiment, the manual adjustment structure includes a slider 551, a first magnetic block 552, and a second magnetic block 553. The sliding block 551 is slidably disposed on the vertical rod 411, and is kept stationary relative to the vertical rod 411 in a natural state. Preferably, the sliding block 551 is in interference fit with the vertical rod 411, and the sliding block 551 can slide on the vertical rod 411 after a certain external force is applied to the sliding block 551. The first magnetic block 552 is fixed to the other end of the ratchet 54, the first magnetic blocks 552 are arranged in one-to-one correspondence with the ratchet 54, the second magnetic block 553 is fixed to the slider 551, and only one second magnetic block 553 is provided. When the slider 551 moves to the position of the second through hole 53 inserted with the adjustment lever 52, the first magnetic block 552 is just opposite to the second magnetic block 553, and a magnetic attraction is generated between the first magnetic block 552 and the second magnetic block 553, so that the first magnetic block 552 drives the other end of the pawl 54 to move, and the pawl 54 is separated from the ratchet 521. After moving the slider 551 to another position, the pawl 54 is reset by its own elastic force, thereby restoring the engagement with the ratchet 521. The manual adjusting structure has a simple structure, is convenient to operate, and can change the matching relation between the pawl 54 and the ratchet 521 at different positions without arranging too many parts.

In one embodiment, the holder 41 is provided with a plurality of hooks 60 at intervals in a longitudinal direction, and the other end of the second elastic string 451 is provided with a hanging ring 453 engaged with the hooks 60. The hanging ring 453 may be hooked into the hook 60 to change the suspended position of the pressing cover 44, or the force applied by the pressing cover 44 to the tubular container 30 to press the tubular container 30 may be increased or decreased in the case where the suspended position of the pressing cover 44 is not changed. With the above arrangement, it is possible to use different types of tubular containers 30.

In one embodiment, the bottom of the gland 44 is provided with a flexible pad 442, and the gland 44 is held in contact with the top of the tubular container 30 by the flexible pad 442. Because the tubular container 30 moves in the horizontal direction relative to the pressing cover 44 at the contact part of the pressing cover 44 and the tubular container 30, the tubular container 30 can be ensured to move freely in the horizontal direction by the simple flexible pad 442, the interference of the pressing cover 44 on the movement of the tubular container 30 in the horizontal direction is reduced, and the uniform mixing effect of the solution in the tubular container 30 is ensured.
