In order to develop and optimize these high-performance materials, accurate material characterization and analysis become essential. Among them, the microstructure, particle size, and morphology of the material have a direct impact on the battery performance. Therefore, these materials need to be finely ground to obtain samples suitable for characterization. When handling these sensitive materials, especially when the sample may be affected by temperature and change its chemical or physical properties, cryo-grinding becomes an important technique.

[0039] The pulling assembly includes: a side of the movable seat 8 is rotatably connected to a pulling slat 10, and one end of the pulling slat 10 is rotatably connected to a rotating and pulling handle 11, a side of the supporting upright plate 1 is movably connected to a sliding block 22, and one end of the rotating and pulling handle 11 is rotatably connected to the sliding block 22, and a return spring 3 is installed on the outer side of the adjustable support plate 7 and the pulling slat 10, and the return spring 3 is used to provide support for the movable seat 8, the pulling slat 10 and the rotating and pulling handle 11 to prevent the movable seat 8, the pulling slat 10 and the rotating and pulling handle 11 from moving ineffectively outside the first guide rod 9;

[0040] The pulling slat 10 and the movable seat 8, the pulling slat 10 and the rotating handle 11, and the rotating handle 11 and the sliding block 22 are all rotatably connected through a rotating shaft. It can be understood that the pulling slat 10 and the movable seat 8, the pulling slat 10 and the rotating handle 11, and the rotating handle 11 and the sliding block 22 can also be rotatably connected together in a hinged installation manner;

[0041] A second arc-shaped groove 19 is formed on the surface of the tank cover clamping seat 17, and a first arc-shaped groove 18 is formed on the surface of the movable seat 8, and the inner diameter of the first arc-shaped groove 18 is greater than the inner diameter of the second arc-shaped groove 19;

[0045] A first threaded hole is formed on the surface of the movable collar 14, and a first positioning bolt 15 is meshedly connected inside the first threaded hole;

[0046] A guide slide 2 is provided on the side of the support vertical plate 1, and a sliding block 22 is slidably connected to the inside of the guide slide 2. A positioning sheet 20 is connected to the outside of the sliding block 22, and a second threaded hole is provided on the surface of the positioning sheet 20. A second positioning bolt 21 is meshed and connected inside the second threaded hole.

[0047] A positioning assembly 5 is provided on the surface of the supporting vertical plate 1, and the positioning assembly 5 is used to define the position of the grinding jar;

[0048] The positioning component 5 comprises:

[0049] A fixed block 51 is connected to the surface of the support upright 1, and a fixed rod 54 is fixedly connected to the outer side of the fixed block 51, and a support sheet 56 is arranged at one end of the fixed rod 54 away from the fixed block 51, and a moving collar 52 is movably sleeved on the outer side of the fixed rod 54, and a clamping block 55 is fixedly connected to the outer side of the moving collar 52, and a positioning spring 53 is installed on the side where the moving collar 52 and the supporting sheet 56 are close to each other, and the positioning spring 53 is sleeved on the outer side of the fixed rod 54, and the number of the preferred fixed rods 54 is set to two, that is, the number of the moving collar 52, the positioning spring 53 and the clamping block 55 is also two;

[0050] The sides of the fixing block 51 and the clamping block 55 close to each other are respectively provided with a first positioning groove and a second positioning groove. It can be understood that the shapes of the first positioning groove and the second positioning groove can be arc-shaped or square-shaped, so that the positioning component 5 can not only position a cylindrical grinding jar, but also a square columnar grinding jar.

[0051] In one embodiment of the utility model, the can opening device is targeted at a cylindrical grinding jar, and the cover of the cylindrical grinding jar is also cylindrical, and the shape of the second arc-shaped groove 19 is adapted to the shape of the grinding jar cover, that is, the grinding jar cover can be stably stuck inside the second arc-shaped groove 19;

[0052] Before using the device to open the grinding jar, the height of the jar cover clamping seat 17 can be adjusted according to the actual height of the grinding jar, so that after the grinding jars of different heights are stably clamped by the positioning component 5, the jar covers of the grinding jars can be clamped into the second arc-shaped groove 19. The specific operation of adjusting the height of the jar cover clamping seat 17 is that the staff first rotates the first positioning bolt 15 and the second positioning bolt 21 out of the first threaded hole and the second threaded hole respectively, and then grabs the adjustable support plate 7 and the movable seat 8 by hand, and moves them up and down, so that the adjustable support plate 7 and the movable seat 8 together pull the slats 10 and the rotating handle 1 1. The sliding block 22, the connecting strip 16, the connecting rod 12 and the movable collar 14 move up and down. After the tank cover clamping seat 17 is adjusted to a suitable height, the first positioning bolt 15 and the second positioning bolt 21 are successively inserted into the first threaded hole and the second threaded hole and tightened, so that one end of the first positioning bolt 15 is firmly against the outer side of the second guide rod 13, and one end of the second positioning bolt 21 is firmly against the inner wall of the guide slide 2, so that the movable collar 14 is stably limited on the second guide rod 13, the positioning sheet 20 and the sliding block 22 are stably limited on the supporting vertical plate 1, and then the position of the tank cover clamping seat 17 is properly adjusted;

[0053] Through the above technical solution, before opening the grinding jar, the height of the second arc-shaped groove 19 can be conveniently adjusted according to the actual height of the grinding jar, so that the second arc-shaped groove 19 can clamp the lids of the grinding jars of different heights and open the grinding jars of different heights, thereby improving the application range of the present can opening device.

[0054] After the position of the jar cover clamping seat 17 is adjusted appropriately, the staff should use the positioning assembly 5 to stably position the grinding jar body. The specific operation is that the staff first pulls the clamping block 55 outward by hand to make the clamping block 55 away from the fixed block 51, and the movable ring 52 connected to the outside of the clamping block 55 will slide on the outside of the fixed rod 54, and at this time, the positioning spring 53 arranged between the supporting sheet 56 and the movable ring 52 is in a compressed state. Then, the staff puts the grinding jar body into the first positioning groove, and after it is properly placed, releases the clamping block 55, so that the positioning spring 53 with tension drives the movable ring 52 and the clamping block 55 to press against the grinding jar body, so as to stably limit the grinding jar body on the fixed block 51;

[0055] Through the above technical solution, the position of the grinding jar to be opened can be conveniently and stably limited, so that during the opening process, the grinding jar can only move between the fixed block 51 and the clamping block 55 without tilting, thereby improving the stability of the grinding jar when it is opened. In addition, through the design of the first positioning groove and the second positioning groove, grinding jars of different outer diameters and specifications can be limited between the fixed block 51 and the clamping block 55, thereby improving the application range of the can opening device;

[0056] After the grinding jar body is stably limited on the positioning assembly 5, the grinding jar is placed in a state where its body is stably placed between the fixing block 51 and the clamping block 55, and its jar cover is stably clamped inside the second arc-shaped groove 19, and then the can opening operation is performed. The specific operation is that the staff holds the rotating and pulling handle 11 by hand and pulls it downward, so that the rotating and pulling handle 11 drives the pulling slat 10 and the movable seat 8 to move outside the first guide rod 9, and the pulling slat 10 will also stretch the reset spring 3, thereby causing the movable seat 8 to move toward the direction of the positioning assembly 5. It can be understood that since the inner diameter of the second arc-shaped groove 19 is smaller than the inner diameter of the first arc-shaped groove 18, the movable seat 8 will not contact the bottle cap of the grinding jar when moving, but will contact the bottle body of the grinding jar, and then the movable seat 8 moving downward will abut against the bottle body of the grinding jar, and since the jar cover of the grinding jar is firmly stuck in the second arc-shaped groove 19, the jar cover of the grinding jar will gradually separate from the jar body of the grinding jar until the can opening operation is completed;

[0057] Through the above-mentioned can opening operation, the jar cover and the jar body of the grinding jar can be separated smoothly and smoothly, and the jar body will not shake or tilt during the process of the jar cover and the jar body being separated, thereby preventing the material in the grinding jar from spilling out, thereby improving the stability of opening the grinding jar.

[0058] Preferably, a first anti-detachment sheet is provided at one end of the second guide rod 13 away from the supporting vertical plate 1, and a second anti-detachment sheet is provided at one end of the first guide rod 9 away from the adjustable support plate 7, thereby preventing the movable ring 14 from detaching from the second guide rod 13 and preventing the movable seat 8 from detaching from the first guide rod 9.

[0059] Preferably, a receiving groove 24 is provided on the surface of the supporting vertical plate 1, and the interior of the receiving groove 24 is rotatably connected to a rotating rod 23 via a damping shaft, and a fastening clamp 25 is installed on the outer side of the rotating rod 23, so that the fastening clamp 25 can be conveniently used to fix the supporting vertical plate 1 on other columnar objects.

[0060] In this embodiment, a base frame 4 is provided on the surface of the supporting plate 1, and a storage groove 6 is installed on the outer side of the base frame 4, so that the bottle body of the grinding jar after opening will fall on the storage groove 6, and the staff does not need to use other tools to clamp the grinding jar.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
