Technical Field

[0001] This utility model belongs to the field of laboratory equipment technology, and specifically relates to a device for clamping and picking up batches of digestion beakers. Background Technology

[0002] In the fields of chemical analysis and environmental monitoring, batch digestion beakers are commonly used for sample pretreatment under high temperature and high pressure conditions. These beakers often retain strong acids, organic solvents, or solid deposits after use, requiring timely cleaning to avoid cross-contamination. Traditional clamping devices can only transfer the beakers, requiring subsequent manual washing or reliance on separate cleaning equipment; while dedicated cleaning equipment can perform spraying, it requires separate placement of the beakers and execution of the cleaning procedure, making it impossible to immediately address residues during the clamping process.

[0025] In some implementations, refer to Figure 1 and Figure 2A device for gripping batch digestion beakers includes: a vertical gripping mechanism comprising a sleeve 1, a pull rod 5, and a clamping plate 8, the clamping plate 8 being hinged to the pull rod 5 for vertical gripping; and an active cleaning module comprising a scraper 1010 folded to the side of the clamping plate 8 for actively cleaning the beakers. Specifically, the device for gripping batch digestion beakers includes a vertical gripping mechanism and an active cleaning module. The vertical gripping mechanism consists of a sleeve 1, a pull rod 5, and a clamping plate 8. The clamping plate 8 is hinged to the pull rod 5. When the pull rod 5 moves up and down within the sleeve 1, it uses the lever principle to drive the clamping plate 8 to rotate around the hinge point, thereby achieving vertical gripping of the beakers by the clamping plate 8. This process uses the hinge point between the clamping plate 8 and the pull rod 5 to form a fulcrum, converting the vertical force applied by the operator to the pull rod 5 into a vertical force. The horizontal clamping force of the clamping plate 8 on the side wall of the beaker, combined with the reaction force of the side wall of the beaker on the clamping plate 8, ensures clamping stability. The active cleaning module includes a scraper 1010 folded into the side of the clamping plate 8. When not in operation, the scraper 1010 is attached to the inner wall of the clamping plate 8 to save space. When in operation, the scraper 1010 is extended and flipped to contact the outer wall of the beaker. When the device is moved after being attached to the beaker, the scraper 1010 uses the friction between its rigid edge and the surface of the beaker to scrape off residual stains, so that the attached substances are removed from the surface of the beaker.

[0026] It should be noted that the scraper 1010 here is only one way to implement the active cleaning function of the active cleaning module. The active cleaning module can also achieve its active cleaning function in other ways. For example, the original fixed scraper 1010 can be replaced with a detachable rotating brush head. The brush head is driven by a micro motor and the bristles adopt a gradient hardness design, with hard bristles at the top for cleaning and soft bristles at the bottom for polishing. The brush head is connected to the clamping plate 8 through a snap-fit ​​structure, which supports quick replacement to adapt to different types of stains. For example, the original fixed scraper 1010 can be replaced with a double-sided scraper. The double-sided scraper is divided into side A and side B. Side A is a soft silicone velvet surface used to clean liquid accumulation on the cup wall, and side B is a hard corrugated surface used to scrape solid deposits on the cup wall.

[0027] The cooperative relationship between clamping plate 8 and scraper 1010 is as follows: when the vertical clamping mechanism clamps the beaker, clamping plate 8 retracts inward to fit the beaker, and at the same time triggers scraper 1010 to unfold from the side of clamping plate 8; at this time, scraper 1010 is connected to clamping plate 8 through hinge point, and scraper 1010 flips to working angle. The two work together to realize the workflow of cleaning first and then clamping. During the cleaning work, clamping plate 8 is kept in a state of fitting against the beaker wall but not clamping tightly. On the one hand, it gives scraper 1010 enough working space, and on the other hand, it avoids that the scraper 1010 cannot make movement relative to the beaker wall due to clamping, thus weakening its cleaning effect. When the cleaning work is completed, clamping plate 8 is driven to clamp the beaker to realize the clamping of the beaker.

[0028] The technical problem this application aims to solve is that traditional clamping tools can only fix and move beakers, and cannot integrate the function of cleaning the outer wall while performing the transfer work. This results in stains remaining and affecting subsequent experiments or requiring secondary cleaning. The vertical clamping mechanism of this application achieves single-handed operation by means of the mechanical structure of the sleeve 1, the pull rod 5 and the clamping plate 8, thereby simplifying the operation. The scraper 1010 of the active cleaning module unfolds by utilizing the energy of the clamping action and cleans the beaker in real time through friction before the beaker is moved. The two are triggered by the displacement of the clamping plate 8 to activate the scraper 1010, thereby completing the clamping transfer and surface cleaning in a single operation, improving experimental efficiency and avoiding the risk of contamination.

[0029] In some implementation methods, refer to Figure 2 and Figure 3 The active cleaning module also includes: The flipping assembly, connected to the scraper 1010, drives the scraper 1010 to flip relative to the clamping plate 8. Specifically, the flipping assembly is a mechanical linkage device connected to the scraper 1010 to drive the scraper 1010 to flip relative to the clamping plate 8, thereby optimizing the cleaning angle to adapt to different beaker shapes. During operation, when the position of the scraper 1010 needs to be adjusted, the flipping assembly responds to the drive signal and drives the scraper 1010 to rotate. It achieves operation through the lever principle. By setting a rotation fulcrum, it utilizes the torque balance effect to reduce the operating force, that is, a small input force can be converted into a large displacement, thus easily completing the flipping angle adjustment.

[0030] An interactive component is located on the upper end of the lever sleeve 1 and connected to the flipping component to facilitate operation of the flipping component. Specifically, the interactive component is a control handle or button located on the upper end of the lever sleeve 1. Its purpose is to allow users to directly operate the flipping component without bending over or using additional tools. During operation, the user operates the interactive component by hand, and signals are transmitted to the flipping component through a mechanical connection. This is then linked by the lever or connecting rod 7 to achieve remote transmission of force. In other words, the micro-motion of the interactive component can be amplified into the motion of the flipping component, thereby improving the convenience of human-machine interaction and facilitating the operator's operation of the scraper 1010 and its flipping.

[0031] It should be noted that the flipping component and the interactive component can include various schemes to achieve the adjustment of the flipping angle of the scraper 1010. For example, the interactive component uses a force-saving lever handle, and the flipping component uses a cam push rod mechanism. The lever fulcrum is fixed to the sleeve 1, the long lever arm is provided with a handle, and the short lever arm contacts the cam profile through a roller; the cam base circle is fixedly connected to the rotating shaft of the scraper 1010, and the push rod is hinged to the base of the clamping plate 8. When the user presses down the handle, the short lever arm pushes the cam roller, forcing the cam to rotate around the axis. The cam lift segment pushes the push rod to move linearly, which is converted into the flipping motion of the scraper 1010 around the fulcrum; after releasing the handle, the return spring 6 makes the cam rotate back to the initial position; for example, the interactive component uses a knob gear set, and the flipping component uses a rack and pinion mechanism. The knob shaft meshes with a small gear, which drives a large gear to achieve first-stage reduction. The large gear is coaxially fixed to a sector rack, which meshes with the arc-shaped toothed track on the back of the scraper 1010. The rotating shaft of the scraper 1010 is limited to the clamping plate 8 by a bearing. When the user rotates the knob, the small gear drives the large gear to rotate at a low speed, and the sector rack swings accordingly and drives the arc-shaped toothed track, converting the rotational motion of the gear into the fixed-axis rotation of the scraper 1010. The gear's self-locking characteristic can keep the angle of the scraper 1010 stable when there is no operation.

[0032] In some implementations, refer to Figure 2 The flipping assembly includes: a drive rod 1009 and a sliding plate.

[0033] The drive rod 1009 is hinged to the scraper 1010. Specifically, the drive rod 1009 of the flipping assembly is a rigid connecting rod 7, which is hinged to the side end of the scraper 1010. Its purpose is to transmit the linear motion of the sliding plate and convert it into the adjustment of the flipping angle of the scraper 1010. When the sliding plate is displaced, the drive rod 1009 pushes the scraper 1010 to rotate around the hinge point, converting the linear input into the angle output, and reducing the operating force requirement through torque balance.

[0034] A sliding plate is embedded in the outer edge of the clamping plate 8 and can slide within it. The sliding plate is connected to the scraper 1010 via a drive rod 1009. Specifically, the sliding plate is a plate-like structure embedded in a groove 1201 on the outer edge of the clamping plate 8. Its purpose is to receive the manipulation input of the interactive component and drive the drive rod 1009 to move. The user operates the interactive component to move the sliding plate along the groove 1201 of the clamping plate 8, and achieves smooth displacement by utilizing the characteristic of low sliding friction resistance.

[0035] The sliding plate and the drive rod 1009 have a cooperative relationship: when the sliding plate moves horizontally, it pushes the scraper 1010 to flip through the drive rod 1009. In the process, the linear motion of the sliding plate is converted into the rotational motion of the scraper 1010 through the drive rod 1009. The purpose is to adjust the contact angle between the scraper 1010 and the inner wall of the beaker to fit the surface of the beaker. The energy transfer is achieved through the optimization of the hinge point position.

[0036] In some implementations, refer to Figure 2 A tension spring 1006 is suspended on the sliding plate, with its other end connected to the surface of the sleeve 1. Specifically, the tension spring 1006 is a helical elastic element with its two ends suspended on the surfaces of the sliding plate and the sleeve 1, respectively. Its purpose is to automatically reset the sliding plate and the linkage components in the non-operating state, reducing manual reset steps and ensuring the stable retraction of the scraper 1010. When the user releases the interactive component, the tension spring 1006 drives the sliding plate back to its original position along the slide groove 1201, thereby achieving precise reset.

[0037] In some implementations, refer to Figure 3 and Figure 2 The interactive components further include a rotating ring 1001, a guide groove 1002, a sliding column 1003, a guide plate 1005, a transmission rod 1004, and a pressure rod 1008, wherein: The rotating ring 1001 is sleeved on the outer wall of the middle section of the vertical clamping mechanism and can rotate. Specifically, the rotating ring 1001 is a ring-shaped component sleeved on the middle section of the rod sleeve 1. Its purpose is to provide a rotating operation interface for easy one-handed control by the user. When the user rotates the rotating ring 1001, its internal guide groove 1002, which is a spiral groove structure, converts the rotational motion into axial displacement. The inclined design of the helix angle decomposes the rotational tangential force into an axial component. The guide groove 1002 is a spiral groove provided inside the rotating ring 1001 to convert the rotational motion of the rotating ring 1001 into axial displacement. The sliding column 1003 is embedded in the guide groove 1002 and can move axially with the rotation of the rotating ring 1001. Specifically, the sliding column 1003 is a columnar slider 1202 embedded in the guide groove 1002, which moves along a spiral trajectory with the rotation of the rotating ring 1001, with the purpose of transmitting the linear displacement after motion conversion. The guide plate 1005 is embedded on the outside of the sleeve 1 and can slide up and down along the outside of the sleeve 1. Specifically, the guide plate 1005 is a plate-shaped structure that is embedded in the vertical guide rail on the outside of the sleeve 1 and can slide up and down. Its purpose is to receive the displacement input of the sliding column 1003 and maintain the vertical movement trajectory. The transmission rod 1004 is used to connect the sliding column 1003 and the guide plate 1005. Specifically, the transmission rod 1004 is a rigid connecting rod with the sliding column 1003 and the guide plate 1005 hinged at both ends, so as to transmit the axial displacement of the sliding column 1003 to the guide plate 1005.

[0038] The pressure rod 1008 is used to connect the guide plate 1005 and the flipping assembly. Specifically, the pressure rod 1008 is another rigid link 7 that connects the guide plate 1005 and the sliding plate of the flipping assembly. Its purpose is to convert the displacement of the guide plate 1005 into a thrust on the sliding plate.

[0039] The spiral drive design of the rotating ring 1001 and the guide groove 1002 allows the user to control the angle of the scraper 1010 by rotating it with one hand. Combined with the force direction conversion mechanism of the pressure rod 1008 and the guide plate 1005, the vertical displacement is efficiently converted into horizontal thrust. Thus, the problem of insufficient operation coordination is solved by the multi-stage motion conversion of the mechanical linkage chain, which improves the efficiency and safety of single-handed operation in batch processing.

[0040] In some implementations, refer to Figure 4 The active cleaning module also includes a cleaning component, including a mist nozzle, for spraying cleaning agent onto the outer wall of the beaker. Specifically, the cleaning component is a structure including a spray nozzle 1108, integrated into the outer edge of the clamp 8. Its purpose is to spray atomized cleaning agent onto the outer wall of the beaker to dissolve stubborn residues. When the clamp 8 holds the beaker, an external cleaning agent source delivers liquid to the mist nozzle through a pipeline. The liquid is sprayed onto the beaker wall under high pressure. Combined with the scraper 1010 in the active cleaning module, the cleaning efficiency is improved through a dual mechanism of chemical dissolution and physical rinsing, further enhancing the cleaning efficiency and safety of batch digestion experiments.

[0041] The piston cylinder 1103 is fixed to the side wall of the rod sleeve 1 to form a cavity for containing cleaning agent. Specifically, the piston cylinder 1103 is a cylindrical cavity fixed to the side wall of the rod sleeve 1, with a reciprocating piston inside. Its purpose is to store and pump cleaning agent to form a self-sufficient fluid supply system. When the clamping mechanism is activated, the up and down movement of the pull rod 5 drives the piston to reciprocate inside the piston cylinder 1103 through mechanical linkage, thereby creating liquid pressure inside the piston cylinder 1103 and causing the internal liquid to be sprayed out from the spray head 1108.

[0042] In some implementations, refer to Figure 4 The cleaning assembly also includes: a first one-way valve 1104, which is located at the liquid inlet end of the piston cylinder 1103 and connected to a suction pipe 1105; specifically, the first one-way valve 1104 is a valve body that only allows one-way flow, located at the liquid inlet end of the piston cylinder 1103 and connected to the suction pipe 1105, the purpose of which is to draw liquid from an external cleaning agent source and prevent backflow when the piston retracts. When the piston retracts and the pressure inside the cylinder is lower than that outside, the valve core is opened by external hydraulic pressure, and the liquid flows into the cavity. When the piston advances, the valve core is automatically closed by the high pressure inside the cylinder.

[0043] The second one-way valve 1106 is located at the liquid outlet end of the piston cylinder 1103 and is connected to a diversion pipe 1107. Specifically, the second one-way valve 1106 is another type of one-way valve body, located at the liquid outlet end of the piston cylinder 1103 and connected to the diversion pipe 1107. The diversion pipe 1107 is connected to the mist nozzle. Its purpose is to direct the detergent to the mist nozzle and prevent backflow when the piston is pushed forward. The working principle is also based on pressure difference control. When the piston is pushed forward, the high pressure causes the valve core to open and output liquid. When the piston is pulled back, the valve core closes due to negative pressure to maintain the pipeline pressure. When the user pulls down the lever 5, the linkage mechanism drives the piston to pull back, the first one-way valve 1104 opens to draw in the detergent. When the lever 5 is pushed up, the piston is pushed forward, the second one-way valve 1106 opens and forces the detergent into the mist nozzle through the diversion pipe 1107, realizing the synchronous triggering of the clamping action and the detergent supply.

[0044] The self-supply design of piston cylinder 1103 and one-way valve group automatically triggers the spraying of cleaning agent through the mechanical linkage of clamping action, so as to achieve stable fluid pressure output. Combined with the atomization mechanism of the mist nozzle, the cleaning agent is evenly covered on the outer wall of the beaker, thereby improving the cleaning efficiency in conjunction with the cleaning of the inner wall of scraper 1010. Furthermore, the problem of interruption of the cleaning process by manual liquid replenishment is solved through the coordinated conversion of mechanical energy and fluid energy, thereby improving the continuity and cleaning efficiency of batch digestion experiments.

[0045] In some implementations, refer to Figure 4 The cleaning assembly also includes a transmission plate 1101 and a piston rod 1102. The transmission plate 1101 is fixed to the lower end of the pull rod 5 and moves with the pull rod 5. Specifically, the transmission plate 1101 is a rigid plate that is fixed to the lower end of the pull rod 5 and moves synchronously with it. Its purpose is to directly transmit the vertical displacement of the pull rod 5 to the piston rod 1102, thereby realizing the mechanical linkage between the clamping action and the pumping of the cleaning agent.

[0046] The piston rod 1102 is hinged to the lower end of the transmission plate 1101 to form a sealed cavity together with the piston cylinder 1103. Specifically, the piston rod 1102 is a rod-shaped component with its upper end hinged to the lower end of the transmission plate 1101 and its lower end extending into the piston cylinder 1103 and fixed to the piston, forming a sealed cavity together with the piston cylinder 1103. The purpose is to convert the linear motion of the pull rod 5 into the reciprocating motion of the piston to pump the cleaning agent.

[0047] The rigid linkage design of the transmission plate 1101 and the piston rod 1102 synchronously triggers the clamping and pumping actions through the single operation of the pull rod 5, ensuring the synchronization of cleaning agent spraying and beaker release. Combined with the degree-of-freedom compensation mechanism of the hinge structure, motion interference is avoided. Thus, the problem of low efficiency of manual step-by-step operation is solved through the efficient integration and conversion of mechanical energy, improving the continuity and operational safety of batch digestion experimental beaker cleaning work.

[0048] In some implementations, refer to Figure 4 and Figure 5 The cleaning assembly also includes a connecting assembly, comprising a slide groove 1201, an adjusting ring 1203, and a slider 1202. The slide groove 1201, milled onto the surface of the piston rod 1102, has a horizontally extending linkage section and a vertically extending decoupling section for controlling the linkage state. Specifically, the slide groove 1201 is a mechanical track on the surface of the piston rod 1102. Its horizontally extending linkage section restricts the lateral displacement of the slider 1202, thus rigidly connecting the piston rod 1102 and the transmission plate 1101, ensuring the synchronization of the cleaning action and the clamping operation. The vertically extending... The decoupling section allows the slider 1202 to slide freely longitudinally, thus decoupling the mechanical coupling between the two. When the slider 1202 is restricted in the horizontal section, it retains only the axial degree of freedom, achieving linkage; after entering the vertical section, it restores the radial degree of freedom, achieving decoupling. The adjusting ring 1203 and the slider 1202 are both involved. The adjusting ring 1203 is exposed on the surface of the sleeve 1. Rotating the adjusting ring 1203 drives the slider 1202 to move within the groove 1201. Specifically, the adjusting ring 1203 is exposed on the rotating control component of the sleeve 1, and its inner wall has a threaded structure, forming a threaded pair with the slider 1202. When the adjusting ring 1203 is rotated, the angular displacement of the ring body is converted into the axial displacement of the slider 1202, driving the slider 1202 to move along the groove 1201, achieving rapid switching of the linkage mode to meet the needs of different operation stages. The slider 1202, as a motion transmission medium, moves along the groove 1201 under the drive of the adjusting ring 1203. When the slider 1202 is in the horizontal section, its sidewall is in contact with the horizontal wall of the groove 1201, so that the piston rod 1102 is rigidly connected to the transmission plate 1101; when the slider 1202 enters the vertical section, the groove wall releases the radial constraint on the slider 1202, allowing the slider 1202 to slide freely in the vertical direction, so that the slider 1202 cannot drive the piston rod 1102, and the linkage is released.

[0049] In some implementations, refer to Figure 4 and Figure 5 The connecting assembly also includes an elastic plate 1204 and a protrusion 1205, connected to the bottom of the adjusting ring 1203, for providing tactile feedback for gear shifting. Specifically, the elastic plate 1204 and the protrusion 1205 are feedback mechanisms connected to the bottom of the adjusting ring 1203. The elastic plate 1204 is a plastic spring, and the protrusion 1205 is a rigid protrusion. When the adjusting ring 1203 rotates to the position of the switching slot of the slider 1202, the protrusion 1205 engages with the groove 1206 on the piston rod 1102, the elastic plate 1204 undergoes elastic deformation and generates a rebound force, providing tactile feedback for gear shifting and realizing physical cues for operation.

[0050] In some implementations, refer to Figures 1 to 7 Preliminary assembly of an apparatus for gripping batch digestion beakers: 1.1 Insert the pull rod 5 into the rod sleeve 1 from bottom to top, and then insert the return spring 6 and the connecting rod 7 into the lower end in sequence.

[0051] 1.2 Hinge the two sides of the connecting rod 7 to the clamping plate 8 respectively to ensure that the center line of symmetry coincides with the axis of the sleeve 1.

[0052] 1.3 Place the adjusting sleeve 2 on the upper end of the rod sleeve 1, and then weld the fixing handle 3 to the adjusting sleeve 2 as a whole.

[0053] 1.4 Install the adjusting component 9 into the adjusting sleeve 2: First, lock the limiting block 901 to the top of the pull rod 5; then, insert the positioning spring 904, the pull plate 905, and the pin 906 into the side cavity of the adjusting sleeve 2 in sequence, so that the front end of the pin 906 can be inserted into the array of positioning holes 907.

[0054] 1.5 The rotating ring 1001 is fitted onto the outer circle of the middle section of the rod sleeve 1. The sliding column 1003 of the scraper assembly is first placed into the guide groove 1002, and then the transmission rod 1004, guide plate 1005, slide plate 1007 and scraper 1010 are installed in sequence. The two ends of the tension spring 1006 are respectively hooked to the slide plate 1007 and the rod sleeve 1.

[0055] 1.6 Cleaning assembly installation: Fix piston cylinder 1103 to the side wall of rod sleeve 1, piston rod 1102 passes through piston cylinder 1103 and is threadedly connected to transmission plate 1101; suction tube 1105 is connected to cleaning liquid bottle, and spray head 1108 faces the opening of clamp plate 8.

[0056] 1.7 The connecting component is located above the cleaning component: The slide groove 1201 is milled on the surface of the piston rod 1102. After the slider 1202 is embedded, it is pressed by the adjusting ring 1203. The elastic plate 1204 and the protrusion 1205 are inserted into the groove 1206 to complete the gear positioning.

[0057] 2. Quick adjustment.

[0058] 2.1 Move the pull plate 905, the pin 906 overcomes the elastic force of the positioning spring 904 and disengages from the positioning hole 907, and the adjusting sleeve 2 is unlocked.

[0059] 2.2 Rotate the movable handle 4 so that the limiting block 901 is aligned with the open end of the limiting groove 902, and the adjusting sleeve 2 can slide up and down along the rod sleeve 1.

[0060] 2.3 After adjustment, rotate the movable handle 4, the limit block 901 is blocked by the stop block 903, and the pull plate 905 will automatically lock when released; the whole operation can be completed with one hand in ≤3 seconds.

[0061] 3. Beaker handling and release.

[0062] 3.1 Hold the fixed handle 3 and the movable handle 4 with one hand, with the web of your thumb and forefinger touching the curved surface of the fixed handle 3, and your index and middle fingers naturally pressing against the movable handle 4.

[0063] 3.2 The movable handle 4 moves closer to the fixed handle 3 → the pull rod 5 moves up → the connecting rod 7 drives the clamping plate 8 to close synchronously. The clamping force is determined by the preload of the return spring 6 and the lever ratio.

[0064] 3.3 Release the movable handle 4, the return spring 6 pushes the pull rod 5 to move down quickly, the clamp 8 automatically opens 8°, and the beaker can be moved out horizontally without any jamming.

[0065] 4. Scraping function.

[0066] 4.1 If there are residual condensate droplets on the outer wall of the beaker, the operator should rotate the rotating ring 100° with their thumb.

[0067] 4.2 The guide groove 1002 drives the sliding column 1003 to move down → the transmission rod 1004 pushes the guide plate 1005 → the pressure rod 1008 presses the sliding plate 1007 to slide outward → the drive rod 1009 makes the scraper 1010 unfold and fit against the outer wall of the beaker.

[0068] 4.3 While lifting the beaker, scraper 1010 scrapes off the liquid droplets; rotate rotating ring 1001 in the opposite direction and tension spring 1006 retracts scraper 1010 to avoid accidental injury.

[0069] 5. Cleaning function.

[0070] 5.1 Before using the rotating adjustment ring 1203, the slider 1202 enters the horizontal section of the slide groove 1201, and the piston rod 1102 forms a rigid linkage with the transmission plate 1101.

[0071] 5.2 During each clamping action, the pull rod 5 moves upward → the transmission plate 1101 drives the piston rod 1102 to compress the piston cylinder 1103 → the cleaning fluid passes through the second one-way valve 1106 → the diversion pipe 1107 → the spray head 1108 and sprays out in a fan-shaped mist, covering the contact area between the clamping plate 8 and the beaker.

[0072] 5.3 After releasing the movable handle 4, the piston rod 1102 returns to its original position, the first one-way valve 1104 opens, and the piston cylinder 1103 automatically replenishes the liquid; rotating the adjusting ring 1203 to the vertical section will turn off the cleaning function.

[0073] 6. Maintenance and Precautions.

[0074] Regularly inject ethanol or laboratory-approved cleaning solution into the inlet of pipette 1105 to prevent crystallization blockage.

[0075] Check the wear of the scraper blade 1010 monthly and replace it if necessary.

[0076] The return spring 6 and the positioning spring 904 have undergone tens of thousands of fatigue tests. It is recommended to apply high-temperature silicone grease every month to maintain their elasticity.

[0077] The entire process is autoclaved, and all metal parts are made of stainless steel, which is resistant to chloride ion corrosion.

[0078] 7. Extended applications.

[0079] By replacing the clamps 8 with different curvatures, it can be extended to round containers such as conical flasks, graduated cylinders, and crucibles; A quick-release interface is added to the top of the sleeve 1, which can be connected to a robotic arm to achieve integration with an automated experimental platform. Through the above complete implementation steps, this application achieves the goals of "multi-purpose clamping, single-handed operation, instant adjustment and locking, and instant clamping and decontamination", significantly reducing the labor intensity of experiments and the risk of cross-contamination, and is suitable for chemical experimental scenarios in multiple fields such as teaching, scientific research, and industrial testing.
