[0026] The utility model sets a telescopic component, and the adjusting seat is connected with the telescopic component so as to be able to follow the telescopic component to move up and down in the vertical direction. The first clamping mechanism and the second clamping mechanism are respectively movably connected with the adjusting seat. When the adjusting seat follows the telescopic component to move upward, the first clamping mechanism and the second clamping mechanism are relatively close to each other. When the adjusting seat follows the telescopic component to move downward, the first clamping mechanism and the second clamping mechanism are relatively far away from each other. The relative distance between the first clamping mechanism and the second clamping mechanism is adjustable, so that the clamping component can clamp test tubes of different sizes and specifications, which effectively solves the problem that the existing mechanical arm adopts a fixed-size clamping mechanism to clamp test tubes, and the clamping mechanism cannot clamp test tubes of different sizes and specifications due to the lack of an adjustment mechanism, thereby limiting the versatility and ease of use of the clamping mechanism.

[0027] Furthermore, the relative distance between the first clamping mechanism 31 and the second clamping mechanism 32 is adjustable so that the clamping assembly 3 can achieve a more stable clamping effect, which helps to reduce the risk of shaking and falling of the test tube during the clamping process, and is beneficial to improving the safety of experiments or production.

[0028] Optionally, in some embodiments, the second clamping mechanism 32 is fixedly connected to the adjustment seat 4, and the first clamping mechanism 31 and the adjustment seat 4 are movably connected so that the first clamping mechanism 31 can move relatively on the adjustment seat 4, thereby enabling the first clamping mechanism 31 to be relatively close to or away from the second clamping mechanism 32.

[0029] Further, as a preferred embodiment of the present invention but not limitation, the first clamping mechanism 31 and the second clamping mechanism 32 are both movably connected to the adjustment seat 4, which is beneficial to improve the adjustability of the clamping assembly 3 and effectively increase the practicality of the device body 1.

[0030] Optionally, in some embodiments, the telescopic assembly 2 includes a hydraulic cylinder and a telescopic rod connected to the hydraulic cylinder, and the telescopic rod is connected to the clamping assembly 3 .

[0031] Optionally, in some embodiments, the telescopic assembly 2 includes a cylinder and a telescopic rod connected to the cylinder, and the telescopic rod is connected to the clamping assembly 3 .

[0032] Further, as a preferred embodiment of the present invention but not limitation, the telescopic assembly 2 includes a telescopic motor 21 and a first telescopic rod 22 connected to an output end of the telescopic motor 21 , and the first telescopic rod 22 is connected to the clamping assembly 3 .

[0033] like Figures 1 to 4 The first clamping mechanism 31 shown includes a first clamping shell 311 and a first clamping mounting portion 312 connected to the first clamping shell 311 . A sliding assembly 5 is provided between the first clamping mounting portion 312 and the adjustment seat 4 .

[0034] Furthermore, the first clamping mechanism 31 and the second clamping mechanism 32 are symmetrically arranged.

[0035] Furthermore, the setting of the sliding component 5 enables the first clamping mechanism 31 to perform precise sliding adjustment relative to the adjustment seat 4; secondly, the setting of the sliding component 5 not only enables adjustment, but also helps to reduce the friction and wear that may be generated during the adjustment process, effectively extending the service life of the clamping component 3.

[0036] like Figures 1 to 4 The telescopic assembly 2 shown includes a telescopic motor 21, a first telescopic rod 22 connected to the output end of the telescopic motor 21, and the sliding assembly 5 includes a first sliding assembly 51, the first sliding assembly 51 includes a first connecting rod 511 located on the adjustment seat 4 and connected to the first telescopic rod 22, and a first swinging member 512 connected to the first connecting rod 511 and hinged to the adjustment seat 4, and the first swinging member 512 is connected to the first clamping mounting portion 312;

[0037] Furthermore, when the telescopic motor 21 is working, the output end of the telescopic motor 21 controls the first telescopic rod 22 to telescope in the vertical direction, and the first telescopic rod 22 is connected to the first connecting rod 511 so that the first connecting rod 511 can move upward or downward along the vertical direction following the first telescopic rod 22.

[0038] Furthermore, the first swinging member 512 and the adjustment seat 4 are connected in a hinged manner, as well as the first swinging member 512 and the first clamping mounting portion 312, so that the first sliding assembly 51 is more compact in structure, which helps to save space, thereby allowing the first clamping mechanism 31 to operate more flexibly in a limited working environment.

[0039] Furthermore, since the first swinging member 512 is hinged to the adjustment seat 4 , the first swinging member 512 can swing within a certain range, thereby better adapting to test tubes of different sizes and specifications.

[0040] like Figures 1 to 4The first connecting rod 511 shown is provided with a connecting groove 5111 at one end close to the first swinging member 512. The first swinging member 512 includes a first horizontal swinging portion 5121 arranged in the horizontal direction and connected to the first connecting rod 511 through the connecting groove 5111, a first vertical swinging portion 5122 arranged in the vertical direction, and a first hinged circular hole 5123 located between the first horizontal swinging portion 5121 and the first vertical swinging portion 5122 and hinged to the adjustment seat 4. The end of the first clamping mounting portion 312 is provided with a mounting circular groove 3121 that is snap-fitted with the first vertical swinging portion 5122, so that the first clamping mounting portion 312 and the first swinging member 512 can be detachably connected.

[0041] Specifically, when the first connecting rod 511 moves downward, the first horizontal swinging portion 5121 located in the connecting groove 5111 is subjected to a downward force, and the first horizontal swinging portion 5121 moves downward following the first connecting rod 511. Since the first vertical swinging portion 5122 and the first horizontal swinging portion 5121 are hinged to the adjustment seat 4 through the first hinge hole 5123, so that the first swinging member 512 can swing on the adjustment seat 4, the first horizontal swinging portion 5121 located at one end of the connecting groove 5111 moves downward, and the first horizontal swinging portion 5121 and the first vertical swinging portion 5122 are hinged to the adjustment seat 4. 2 moves upward, and the first vertical swing portion 5122 is connected to the first clamping mounting portion 312, thereby driving the first clamping mounting portion 312 to move toward the side away from the second clamping mechanism 32; when the first connecting rod 511 moves upward, the end of the first horizontal swing portion 5121 connected to the first connecting rod 511 moves upward, and the end of the first horizontal swing portion 5121 connected to the first vertical swing portion 5122 is subjected to a downward force, thereby driving the first clamping mounting portion 312 to move toward the side close to the second clamping mechanism 32.

[0042] Furthermore, the first hinged circular hole 5123 is hingedly arranged with the adjustment seat 4, which is beneficial to providing the first swinging member 512 with the ability to rotate around a fixed point, and effectively increasing the flexibility and adaptability of the structure of the first swinging member 512.

[0043] Furthermore, the mounting circular groove 3121 of the first clamping mounting portion 312 is snap-fitted with the first vertical swinging portion 5122 so that the first clamping mounting portion 312 and the first swinging member 512 can be detachably connected, which helps users to more easily replace and adjust components during assembly and maintenance, thereby improving the flexibility and maintainability of the clamping component 3.

[0044] Optionally, in some other embodiments, the first vertical swing portion 5122 and the mounting circular groove 3121 may be connected by threaded connection.

[0045] like Figures 1 to 4 The adjustment seat 4 shown in the figure is provided with a limiting circular groove 41, the first vertical swinging portion 5122 is clamped with the mounting circular groove 3121 through the limiting circular groove 41, and a limiting space 411 for the first vertical swinging portion 5122 to swing is formed between the limiting circular groove 41 and the first vertical swinging portion 5122;

[0046] Furthermore, a limiting space 411 is formed between the limiting circular groove 41 and the first vertical swing portion 5122, which is conducive to limiting the swing range of the first vertical swing portion 5122, effectively ensuring that the swing range of the first clamping mechanism 31 is limited when clamping the test tube, and avoiding unnecessary out-of-range swinging during the clamping process that may cause the test tube to fall off or be damaged.

[0047] Furthermore, the limiting space 411 can limit the swing range of the first vertical swing portion 5122, thereby avoiding the risk of the first clamping mechanism 31 colliding with other components or workpieces during the clamping process, which is beneficial to protecting the safety of the first clamping mechanism 31 and the test tube.

[0048] like Figures 1 to 4 The sliding assembly 5 shown further includes a second sliding assembly 52, through which the first clamping mounting portion 312 can move relatively in the horizontal direction on the adjustment seat 4;

[0049] Furthermore, the second sliding assembly 52 is arranged so that the first clamping mounting portion 312 can move relatively in the horizontal direction on the adjustment seat 4, which is beneficial for the first clamping mounting portion 312 to be flexibly adjusted in the horizontal direction to adapt to test tubes of different sizes and specifications, and is beneficial for enhancing the adjustment ability and applicability of the first clamping mechanism 31.

[0050] Optionally, in some embodiments, the second sliding assembly 52 includes a slide rail located on the adjustment seat 4 and a guide rail located on the first clamping mounting portion 312, and the first clamping mounting portion 312 can move relatively in the horizontal direction on the adjustment seat 4 through the sliding fit between the slide rail and the guide rail.

[0051] Optionally, in some other embodiments, the second sliding assembly 52 includes a slide rail located on the adjustment seat 4 and a roller assembly located on the first clamping mounting portion 312, and the roller assembly slides with the slide rail to enable the first clamping mounting portion 312 to move relatively in the horizontal direction on the adjustment seat 4.

[0052] Furthermore, as a preferred mode but not limitation of the utility model, the second sliding component 52 includes a sliding groove 521 located on the adjustment seat 4, and a sliding ball component 3122 located on the first clamping mounting portion 312, and the sliding ball component 3122 is slidably connected to the sliding groove 521 so that the first clamping mounting portion 312 can move relatively in the horizontal direction on the adjustment seat 4.

[0053] like Figures 1 to 4 The second sliding assembly 52 shown includes a sliding groove 521 arranged in the horizontal direction and located on the adjustment seat 4, and a sliding ball assembly 3122 arranged in the horizontal direction and located on the first clamping mounting portion 312, and the sliding groove 521 cooperates with the sliding ball assembly 3122 to enable the first clamping mounting portion 312 to move relatively on the adjustment seat 4;

[0054] Furthermore, the cooperation between the sliding groove 521 and the sliding ball assembly 3122 enables the first clamping mounting portion 312 to achieve smooth horizontal movement on the adjustment seat 4, which is beneficial to ensure stability and smoothness during the movement, and effectively ensures that the test tube will not be affected by uneven movement during the clamping process.

[0055] Furthermore, when the sliding ball assembly 3122 moves in the sliding groove 521, the friction is small and evenly distributed, which can reduce the wear of parts and components, effectively extend the service life of the first clamping mounting portion 312, and help reduce maintenance costs and frequency.

[0056] Furthermore, the structures of the sliding groove 521 and the sliding ball assembly 3122 are relatively simple and easy to process and install, so that the structure of the second sliding assembly 52 is more compact.

[0057] like Figures 1 to 4 The first clamping mounting portion 312 is provided with a mounting groove 3123, and the sliding ball assembly 3122 includes a plurality of sliding balls arranged along the length direction of the mounting groove 3123;

[0058] Furthermore, the mounting groove 3123 provides a clear guide path for the sliding ball so that the sliding ball can roll in a predetermined direction, thereby ensuring the stability and accuracy of the first clamping mounting portion 312 during the movement; secondly, since the sliding ball is confined in the mounting groove 3123, the sliding ball is not prone to lateral displacement or jumping, which helps to reduce errors caused by instability during the sliding process.

[0059] Furthermore, when the first clamping mounting portion 312 is subjected to external loads, the multiple sliding beads in the mounting groove 3123 can share these loads together, thereby effectively improving the overall load-bearing capacity and durability; secondly, since the load is dispersed to multiple sliding beads, the local pressure borne by each sliding bead is reduced, which helps to reduce wear and extend service life.

[0060] Furthermore, the sliding ball is arranged along the length direction of the mounting groove 3123, which is beneficial to increase the contact area between the sliding ball and the mounting groove 3123 and reduce the friction resistance during the sliding process.

[0061] like Figures 1 to 4 The first clamping mounting portion 312 shown includes a first clamping mounting block 313, a mounting hole 3131 is provided on the first clamping mounting block 313, and a connecting hole 3111 threadedly matched with the mounting hole 3131 is provided on the first clamping housing 311, so that the first clamping housing 311 and the first clamping mounting portion 312 can be detachably connected;

[0062] Optionally, in some embodiments, the first clamping mounting block 313 and the first clamping housing 311 may be connected in a snap-fit ​​manner.

[0063] Optionally, in some embodiments, the first clamping mounting block 313 and the first clamping housing 311 may be connected in a locking manner.

[0064] Optionally, in some other embodiments, the first clamping mounting block 313 and the first clamping housing 311 may be connected in a slot connection manner.

[0065] Furthermore, as a preferred method but not a limitation of the present invention, the first clamping mounting block 313 and the first clamping shell 311 are connected by a threaded connection. The threaded connection has a high tightening force and self-locking property, which can ensure that the first clamping shell 311 and the first clamping mounting part 312 maintain a tight and stable connection during the connection process.

[0066] Furthermore, by means of threaded fitting, the first clamping shell 311 and the first clamping mounting portion 312 can be quickly and conveniently connected together, and the user does not need to use additional connectors or tools. When the first clamping mounting portion 312 needs to be maintained, replaced or adjusted, the user only needs to simply rotate and separate the threaded connection to easily separate the first clamping shell 311 and the first clamping mounting portion 312, thereby simplifying the disassembly and assembly process.

[0067] like Figures 1 to 4 The cross section of the first clamping mounting block 313 is shown to be rectangular;

[0068] Furthermore, the rectangular cross-section is relatively flat and has clear edges, which can provide a more stable support and fixing effect. During the connection between the first clamping shell 311 and the first clamping mounting portion 312, the rectangular cross-section can ensure that the first clamping mounting block 313 is stably fixed in the first clamping shell 311, effectively avoiding the loosening or falling off of the connection part during operation.

[0069] Furthermore, due to the geometric characteristics of the rectangular shape, the user can more easily and correctly place the first clamping mounting block 313 on the first clamping housing 311, and the adjustment is more accurate and convenient.

[0070] Furthermore, the rectangular cross-section enables the first clamping mounting block 313 to maintain high stability and rigidity when bearing loads, and the four right angles of the rectangle help to disperse and resist forces from all directions, thereby reducing stress concentration caused by irregular shapes; secondly, when clamping or fixing the test tube, the rectangular cross-sectional shape helps to reduce deformation and distortion of the first clamping mounting block 313, ensuring the accuracy and reliability of clamping.

[0071] The implementation method of this embodiment is as follows:

[0072] An improved clamping mechanism comprises a device body 1, the device body 1 comprises a telescopic component 2, a clamping component 3 for clamping a test tube and connected to the telescopic component 2, and an adjustment seat 4 located between the telescopic component 2 and the clamping component 3, the clamping component 3 comprises a first clamping mechanism 31, and a second clamping mechanism 32 arranged corresponding to the first clamping mechanism 31, the first clamping mechanism 31 and the second clamping mechanism 32 are arranged symmetrically, the first clamping mechanism 31 comprises a first clamping mounting portion 312, a sliding component 5 is arranged between the first clamping mounting portion 312 and the adjustment seat 4, the telescopic component 2 comprises a telescopic motor 21, and a second clamping mechanism 32 arranged corresponding to the first clamping mechanism 31.

The second sliding assembly 52 includes a horizontally arranged and located on the adjustment seat 4 The sliding groove 521 and the sliding ball assembly 3122 are arranged in the horizontal direction and located on the first clamping mounting portion 312. The sliding groove 521 cooperates with the sliding ball assembly 3122 to enable the first clamping mechanism 31 to move relatively on the adjusting seat 4.
