I.e. the pallet 5 may be provided with plastic blocks which enable the open container to be secured.
Since the particle sizes of the samples are different, the following examples are provided for the shaker:
when the particle size of the sample to be dissolved is smaller, the sample is accumulated at the bottom of the open container, and although the sample can be dissolved by continuously heating, the dissolving time is different, so in some embodiments, a plurality of mounting holes 6 are formed in the surface of one side of the bracket 3, which is close to the heating table 1, each mounting hole 6 is respectively corresponding to each connecting rod 8, and a limiting clamping hole 7 for limiting all the connecting rods 8 is formed in the surface of the heating table 1;

It should be noted that, in order to ensure stability of the bracket 3 during shaking, a fixed cover may be optionally covered on the outer side of the bracket 3, and the side wall of the fixed cover may be provided with a spring to connect with the bracket 3, so that the position of the bracket 3 is limited and cannot be easily separated from the connecting rod 8.
Example two
When facing samples with larger particle sizes, the samples are easy to accumulate together, and the movement range of the samples in the open container is limited, so that a shaking scheme with respect to a large amplitude is provided, and particularly, a movable cavity 11 is arranged in the bracket 3;

a plurality of pushing members 16 are provided through the fixed sleeve 12, and when the rotary tooth sleeve 14 rotates, the pushing members 16 on each fixed sleeve 12 are pushed by the pushing blocks 15 in turn to guide the open container to shake.
In order to prevent the rotation of the rotary tooth sleeve 14 from being affected, limiting rings at two ends of the rotary tooth sleeve 14 can be arranged on the inner wall of the movable cavity 11, the limiting ring structure is matched with the inner wall of the rotary tooth sleeve 14, and when the rotary tooth sleeve 14 rotates, the rotary tooth sleeve 14 can only rotate around the axial lead of the fixed sleeve 12 due to the limitation of the limiting rings.
In some embodiments, the pushing member 16 comprises a through-column 17 penetrating the fixed sleeve 12, wherein a distance exists between the end of the through-column 17 away from the rotary tooth sleeve 14 and the outer wall of the open container located in the through hole 4 (the distance exists so that the inclined deflection of the open container is not affected), and a pushing inclined column 18 is arranged at the end of the through-column 17 away from the rotary tooth sleeve 14;

Specifically, in order to dissolve the sample with a larger particle size, the open container may be inserted into the constraint ring 20 until the bottom of the open container can be heated in the heating hole slot 2, and then the traction rack 13 may be pushed manually or by a push rod to reciprocate in the movable cavity 11 (refer to fig. 5, the traction rack 13 has a structure of a rod-shaped structure with teeth on both sides, and the number of the teeth is three), that is, the traction rack 13 is driven to move left and right.
When the traction rack 13 moves left and right, all the rotary tooth cases 14 rotate together, then the rotary tooth cases 14 carry the push block 15 to do circular motion around the axial line of the fixed case 12 in intervals, then the push block 15 moves to contact with one compression ball 19 (for example, the compression ball 19 in contact with the push block 15 in fig. 6), then the compression ball 19 is gradually compressed, so that the fluid medium (for example, gas) in the push block is gradually filled into the through column 17 and the push diagonal column 18, as the push diagonal column 18 is filled, the push diagonal column 18 is gradually straightened (i.e., deflected towards the axial line of the fixed case 12), namely, at this moment, the push diagonal column 18 expands and pushes the open container to incline and deflect sideways (at this moment, the constraint ring 20 fixes the top side wall of the open container, so that the inclined deflection motion is performed by taking the contact area with the constraint ring 20 as the rotation center), and as the push block 15 moves away from the compression ball 19, the next compression ball 19 is gradually contacted, so that the open container can move in at least four directions in the four directions (for example, four directions in the northwest directions) in the constraint direction of the open container can reciprocate.
