[0018] See Figure 1-6 , shows a schematic diagram of an embodiment of the present invention that can improve oscillation efficiency, further,

[0019] This device includes a fixed plate 501, a transmission ball 502 is fixedly connected to the fixed plate 501, a connecting block 503 is connected to the fixed plate 501, a base 204 is slidably connected to the connecting block 503, a first tension spring 205 is fixedly connected between the base 204 and the connecting block 503, a bottom ring 201 is rotatably connected to the base 204, a transmission ring 101 is fixedly connected to the bottom ring 201, a plurality of circular holes are opened on the transmission ring 101, a plurality of circular arc protrusions 102 are provided on the transmission ring 101, and the plurality of circular arc protrusions 102 can all contact with the transmission ball 502, a clamping ring 301 is slidably connected to the transmission ring 101, a motor that can drive the bottom ring 201 to rotate is fixedly connected to the base 204, a first electric push rod that can push the clamping ring 301 to slide is fixedly connected to the transmission ring 101, and a battery is fixedly connected to the transmission ring 101, which supplies power to the first electric push rod to avoid line entanglement.

[0020] Insert multiple test tubes to be shaken into the multiple circular holes on the transmission ring 101 in sequence, and make the lower ends of the multiple test tubes to be shaken contact the upper surface of the bottom ring 201. Then slide the clamping ring 301 downward, and then use the clamping ring 301 to squeeze the upper ends of the multiple test tubes to be shaken, so that the clamping ring 301 cooperates with the bottom ring 201 to clamp the multiple test tubes to be shaken, facilitating the subsequent shaking operation;

[0021] Then, the motor is started, and the bottom ring 201 is continuously rotated on the base 204, and the bottom ring 201, the transmission ring 101 and the clamping ring 301 are rotated synchronously, and the multiple test tubes to be shaken are driven to rotate, thereby performing the shaking work. At the same time, when the multiple arc protrusions 102 on the transmission ring 101 move in turn to contact the transmission ball 502, the multiple arc protrusions 102 are pushed by the transmission ball 502 in turn, and then cooperate with the tension of the first tension spring 205 to make the base 204 slide back and forth on the connecting block 503 continuously, and then the bottom ring 201 is continuously rotated while synchronously vibrating in the left and right directions, thereby improving the shaking effect on the multiple test tubes, thereby achieving the purpose of improving the shaking efficiency and ensuring the experimental efficiency. At the same time, since the rotation and left and right sliding of the bottom ring 201 are driven by the motor on the base 204, when the equipment fails and cannot perform the shaking work, it is only necessary to maintain or replace the motor on the base 204, saving maintenance time and reducing the difficulty of subsequent maintenance.

[0022] See Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 , shows a schematic diagram of an embodiment of adjusting the oscillation amplitude according to experimental requirements in accordance with the present invention, further,

[0023] It also includes an adjusting portion 401 slidably connected to the fixed plate 501 , an outer frame ring 202 is fixed to the bottom ring 201 , the adjusting portion 401 can contact the outer frame ring 202 , and a second electric push rod is fixed to the fixed plate 501 that can drive the adjusting portion 401 to slide.

[0024] By operating the adjustment part 401 to slide, the adjustment part 401 can provide a thrust to the bottom ring 201 by pushing the outer frame ring 202, thereby causing the bottom frame 204 to slide to the right on the connecting block 503 against the elastic force of the first tension spring 205, and then adjusting the distance between the transmission ring 101 and the transmission ball 502, so that the distance between the transmission ring 101 and the transmission ball 502 increases, thereby causing the multiple arc protrusions 102 to slide relative to the transmission ball 502, that is, adjusting the starting position of the rotation of the bottom ring 201, and then operating the bottom ring 201 to rotate. At this time, the multiple arc protrusions 102 are When the arc protrusion 102 contacts the transmission ball 502, the stroke that can be moved by the transmission ball 502 becomes shorter, thereby reducing the left and right reciprocating oscillation amplitude of the bottom ring 201, thereby slightly oscillating some test tubes containing relatively fragile experimental samples, while improving the oscillation efficiency and ensuring the integrity of the experimental samples. The operation adjustment part 401 slides in the opposite direction to reduce the distance between the transmission ring 101 and the transmission ball 502, thereby increasing the left and right oscillation amplitude of the bottom ring 201, thereby efficiently oscillating experimental samples that are not easily damaged, thereby improving the oscillation efficiency.

[0025] See Figure 1 , shows a schematic diagram of an embodiment of the present invention for facilitating auxiliary fixation of multiple test tubes, further,

[0026] It also includes an auxiliary ring 203 fixed to the bottom ring 201. Both the outer frame ring 202 and the auxiliary ring 203 are provided with connecting threaded holes. The two rubber rings can be connected to the outer frame ring 202 and the auxiliary ring 203 by screwing in bolts, and the two rubber rings are both oriented towards the centers of the multiple through holes on the transmission ring 101.

[0027] The two rubber rings are connected to the outer frame ring 202 and the auxiliary ring 203 by screwing in bolts respectively, and after both rubber rings are installed toward the centers of the multiple through holes on the transmission ring 101, multiple test tubes are inserted into the multiple through holes on the transmission ring 101, so that the lower ends of the multiple test tubes are wrapped by the rubber rings on the outer frame ring 202 and the auxiliary ring 203, and then the test tubes are auxiliary fixed, thereby improving the fixing effect and further ensuring the stability of subsequent oscillation operations.

[0028] See Figure 1 , shows a schematic diagram of an embodiment according to the present invention for further improving the fixing effect, further,

[0029] A rubber sleeve 103 is provided in the circular hole of each transmission ring 101 .

[0030] When installing multiple test tubes, the multiple test tubes are respectively inserted into the circular grooves at the center of the multiple rubber sleeves 103. During the test tube insertion process, the rubber sleeves 103 will deform due to their own characteristics and then wrap the outer wall of the test tube. After the bottom of the test tube is inserted into contact with the bottom ring 201, the multiple rubber sleeves 103 can wrap the middle of the test tube, thereby further completing the auxiliary fixation task and further ensuring the stability of subsequent oscillation operations.

[0031] See Figure 3 、 Figure 4 、 Figure 7 , shows a schematic diagram of an embodiment of the present invention capable of measuring the clamping force provided by the clamping ring 301 to the test tube, further,

[0032] The test ring 302 is fixed to the clamping ring 301, a vertical rod 406 is slidably connected to the adjusting portion 401, a contact head 407 is fixed to the vertical rod 406, a horizontal slider 403 is slidably connected to the adjusting portion 401, the vertical rod 406 can slide vertically along the adjusting portion 401, the horizontal slider 403 can slide horizontally along the adjusting portion 401, one end of the hinged rod 405 is hinged to the vertical rod 406, the other end of the hinged rod 405 is hinged to the horizontal slider 403, and the horizontal slider 403 is connected to the horizontal slider 403. A second tension spring 404 is fixedly connected to the adjusting part 401, and a pressure sensing block 402 is slidably connected to the adjusting part 401. The pressure sensing block 402 can contact the horizontal slider 403. The upper end face of the test ring 302 is lower than the lower end face of the clamping ring 301. The lower end face of the test ring 302 can contact the contact head 407. A third electric push rod that can push the pressure sensing block 402 to slide is fixedly connected to the adjusting part 401, and a pressure sensor is provided on the side of the pressure sensing block 402 that can contact the horizontal slider 403.

[0033] After a batch of test tubes of the same height are inserted into the circular grooves on the rubber sleeves 103, the pressure sensing block 402 is slid on the adjustment portion 401 to a suitable distance according to the height of the test tubes, and then the clamping ring 301 is operated to slide downward to perform the subsequent clamping and fixing task. When the clamping ring 301 moves downward, the test ring 302 will move downward synchronously with the clamping ring 301. When the test ring 302 slides downward, it will gradually press the contact head 407, and then the vertical rod 406 will slide downward, and then the vertical rod 406 will gradually pull the hinge One end of the connecting rod 405 moves downward, causing the hinged rod 405 to gradually push the horizontal slider 403 to slide on the adjustment portion 401. When the horizontal slider 403 gradually contacts the pressure sensing block 402, the pressure sensor on the pressure sensing block 402 is gradually stressed. The pressure applied to the top of the test tube by the clamping ring 301 after contacting the top of the test tube is then determined by the pressure applied to the top of the test tube. If the pressure is too high, the equipment is stopped in time to perform program changes or equipment maintenance to avoid crushing the test tube and causing damage to the test tube.

[0034] The upper end surface of the test ring 302 is lower than the lower end surface of the clamping ring 301, so that the device can provide a time margin for the staff to stop the operation of the device in time. That is, before the clamping ring 301 contacts the upper end surface of the test tube, the horizontal slider 403 will first contact the pressure sensing block 402, and then the pressure sensing block 402 will be the first to start sensing the pressure number, further avoiding damage to the test tube.

[0035] See Figure 4 , shows a schematic diagram of an embodiment of the present invention in which the contact head 407 is able to be in close contact with the lower end surface of the test ring 302 during operation of the device. Further,

[0036] A second tension spring 404 is fixedly connected between the transverse slider 403 and the adjusting portion 401 .

[0037] The second tension spring 404 can provide tension for the horizontal slider 403, so that the contact head 407 is tightly pressed against the lower end surface of the test ring 302, so that the test ring 302 can push the contact head 407 to slide downward throughout the entire movement when moving downward, thereby ensuring the pressure sensing effect of the pressure sensing block 402 and avoiding damage to the test tube.

[0038] See Figure 3-10 , shows a schematic diagram of an embodiment according to the present invention for further enhancing oscillation efficiency, further,

[0039] It also includes an arc ring 303 fixed to the lower end of the test ring 302 , the connecting block 503 is slidably connected to the fixed plate 501 , and the contact head 407 is provided with an arc chamfer that can contact the arc ring 303 .

[0040] After the pressure measurement is completed, the pressure sensing block 402 is fixed in this position and no longer moves, so that the horizontal slider 403 can no longer slide on the adjustment part 401 in the direction of the pressure sensing block 402, that is, the contact head 407 can no longer slide downward. When the transmission ball 502 cooperates with the arc protrusion 102 to make the base frame 204 slide back and forth left and right on the fixed plate 501, the test ring 302 will slide relative to the contact head 407, and the arc ring 303 on the test ring 302 will gradually contact the arc chamfer on the contact head 407, and then gradually press the base frame 204 to slide up and down on the fixed plate 501, and then make the bottom ring 201 oscillate in the up and down directions while oscillating left and right, thereby further improving the oscillation efficiency.

[0041] See Figure 3-10 , shows a schematic diagram of an embodiment of the present invention in which the outer frame ring 202 can oscillate up and down multiple times. Further,

[0042] A compression spring is fixedly connected between the connecting block 503 and the fixing plate 501 . The compression spring can provide an elastic force greater than the elastic force provided by the second tension spring 404 .

[0043] The elastic force provided by the compression spring enables the base frame 204 to reset on the connecting block 503, and the compression spring can automatically push the connecting block 503 to slide on the fixed plate 501, thereby restoring the connecting block 503 on the fixed plate 501, and then facilitating the outer frame ring 202 to oscillate up and down multiple times;

[0044] The elastic force provided by the compression spring is greater than the elastic force provided by the second tension spring 404, so that when the clamping ring 301 performs a pressure test on the test tube, that is, before the pressure sensing block 402 limits the sliding direction of the horizontal slider 403, the connecting block 503 will not slide on the fixed plate 501, thereby ensuring the normal operation of the equipment.

[0045] See Figure 6 , shows a schematic diagram of an embodiment of reducing equipment operating noise, further,

[0046] It also includes a rubber strip 408 fixedly connected to the adjustment portion 401 .

[0047] The rubber strip 408 can wrap the contact position between the adjusting part 401 and the outer frame ring 202, thereby reducing the noise generated by the outer frame ring 202 repeatedly colliding with the adjusting part 401 during the operation of the equipment, thereby achieving the purpose of reducing the equipment operation noise.

[0048] See Figure 5 , shows a schematic diagram of an embodiment for facilitating fixing of the fixing plate 501, further,

[0049] The fixing plate 501 is provided with a plurality of fixing threaded holes.

[0050] The fixing plate 501 is fixed in the working position by screwing bolts into a plurality of fixing threaded holes, thereby fixing the device.
