[0002] At present, when taking a viscous sample with a relatively high concentration using a measuring cylinder in a laboratory, it is very difficult to pour it out completely, and part of the sample will remain on the inner wall of the measuring cylinder, resulting in problems such as inaccurate measurement and sample waste. Even using a glass rod, it is very difficult to transfer all of it, so there are errors in the experimental results.

[0003] CN221499777U discloses a material taking tool, which includes a straw with a negative pressure channel and a first end and a second end communicated with the negative pressure channel; and a negative pressure module connected to the second end for providing negative pressure to the negative pressure channel. Among them, the straw can suck a plurality of materials into the negative pressure channel through the first end. The material taking tool further includes a material cup, the material cup is provided with a containing cavity for containing materials and an adsorption hole communicated with the containing cavity, the second end is communicated with the containing cavity so that the materials sucked into the negative pressure channel enter the containing cavity, and the adsorption hole is connected to the negative pressure module. However, this material taking tool is more suitable for semiconductor material taking and not suitable for taking materials from a laboratory measuring cylinder.

The telescopic end of the lifting cylinder is vertically downward and detachably fixed on the back plate.

The grasping mechanism further includes a clamping component, and the clamping component includes a pneumatic finger fixed on the lower side of the deflection plate and two clamping plates respectively fixed on two clamping jaws of the pneumatic finger. The outer edges of the two clamping plates are both formed with a front-back symmetrically arranged baffle downwards, and the lower edges of the two baffles are both formed with two left-right symmetrically arranged fork feet. However, this material taking tool is still not suitable for taking materials from a laboratory measuring cylinder.

[0028] Figure 1 This is a sectional view of the present utility model. The present utility model provides a measuring cylinder material taking tool, including: a long handle 1, telescopic handles 2, a material taking surface 3 and a sliding sleeve 7. Among them, the telescopic handle 2 includes a first telescopic handle 2a and a second telescopic handle 2b. One end of the first telescopic handle 2a is hinged to the top end of the long handle 1, and the other end is in a free state. The sliding sleeve 7 is sleeved on the long handle 1 and can move between a first position close to the top end of the long handle 1 and a second position far from the top end of the long handle 1 along the axial extension direction of the long handle 1. One end of the second telescopic handle 2b is hinged to the sliding sleeve 7, and the other end is hinged to the first telescopic handle 2a. When taking materials, the first telescopic handle 2a expands, and the second telescopic handle 2b moves to the first position. After taking the materials, the first telescopic handle 2a closes, and the second telescopic handle 2b moves to the second position. The number of the telescopic handles 2 is at least two, and the at least two telescopic handles 2 are evenly arranged along the circumferential direction of the long handle 1, so that the first telescopic handle 2a among the at least two telescopic handles 2 can form a radial support framework on the circumferential side of the long handle 1, and the material taking surface 3 covers and is fixedly connected to the top end of the support framework.

[0029] Optionally, it further includes a material taking switch 5, and the material taking switch 5 is connected to the sliding sleeve 7 to drive the sliding sleeve 7 to move between the first position and the second position.

[0030] This design is for when taking materials, pressing the material taking switch 5 to drive the sliding sleeve 7 to move to the first position. After taking the materials, pressing the material taking switch 5 again to drive the sliding sleeve 7 to move to the second position.

[0031] Optionally, the edge of the material taking surface 3 is a material taking edge 4, and the material taking edge 4 is fixedly connected to one end of the first telescopic handle 2a in a free state.

[0032] This design is to firmly connect the first telescopic handle 2a to the material taking surface 3. When taking materials, the first telescopic handle 2a expands to provide sufficient supporting force for the material taking surface 3.

[0033] Optionally, the bottom end of the long handle 1 has a handle 6, and the handle 6 is annular or hook-shaped, and the material taking switch 5 is arranged on the handle 6.

[0034] The handle 6 is designed to be annular or hook-shaped to be hung on the shelf of the experimental table, which is clean and tidy and convenient to take at any time.

[0035] Optionally, the long handle 1 is formed by sleeving and connecting multiple sections of long tubes through locking rings.

[0036] The long handle 1 is a plurality of long tubes connected by locking ring sleeves. When no material is taken, the long handle 1 can be shortened to a length close to that of one long tube, which is conducive to saving space.

[0037] Optionally, the first telescopic handle 2a is a plurality of long rods connected by hinges.

[0038] This design is to flexibly adjust the angles between the long rods. When the material picking tool is unfolded, the angles between the multiple long rods are close to 180°. When the material picking tool is closed, the angles between the multiple long rods are close to 0°, which is conducive to saving space.

[0039] Optionally, the long handle 1 and the telescopic handle 2 are made of metal or fiberglass.

[0040] The long handle 1 and the telescopic handle 2 are made of metal or fiberglass to have greater hardness, so as to ensure the stability of the tool during the material removal process.

[0041] Optionally, the material taking surface 3 is made of a flexible material.

[0042] The material taking surface 3 is made of a flexible material, preferably a silicone material, which is relatively soft as a whole, so as to facilitate fully scraping the sample remaining on the inner wall of the measuring cylinder.

[0043] Optionally, the height of the long handle 1 is greater than the height of the measuring cylinder.

[0044] The height of the long handle 1 is greater than that of the measuring cylinder so as to facilitate the material taking tool to be pulled out of the measuring cylinder after taking the material. If it is adapted to measuring cylinders of different heights, material taking tools of different specifications can be produced.

[0045] Optionally, the expanded diameter of the material taking surface 3 is equal to or greater than the diameter of the measuring cylinder.

[0046] The expanded diameter of the material collection surface 3 is equal to or greater than the diameter of the measuring cylinder because if the expanded diameter of the material collection surface 3 is smaller than the diameter of the measuring cylinder, the material collection tool will not be able to scrape the sample remaining on the inner wall of the measuring cylinder. Therefore, theoretically, the expanded diameter of the material collection surface 3 should be equal to the diameter of the measuring cylinder. However, since the material collection surface 3 is made of flexible material, when the expanded diameter of the material collection surface 3 is larger than the diameter of the measuring cylinder, the sample remaining on the inner wall of the measuring cylinder can also be scraped, but it should not be too large.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any modifications or equivalent changes made based on the technical essence of the present invention still fall within the scope of protection required by the present invention.
