[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Combine Figures 1 to 4 The laboratory stirring device shown in the figure includes a gripping handle 1, a transmission rod 2 is provided below the gripping handle 1, a stirring head 3 is provided at the bottom of the transmission rod 2, the stirring head 3 includes a connecting sleeve 31, the connecting sleeve 31 is connected to the transmission rod 2 by screws, an X-shaped oblique stirring rod 32 is fixed on the outside of the connecting sleeve 31, a horizontal stirring rod 33 is provided on the side of the oblique stirring rod 32, the horizontal stirring rod 33 is fixedly connected to the connecting sleeve 31, and a stirring ball 34 is fixed at the end of each of the oblique stirring rod 32 and the horizontal stirring rod 33, a spoiler component 35 is provided on the outside of the horizontal stirring rod 33, and the spoiler component 35 includes a collar 3 51. The collar 351 is rotatably connected to the horizontal stirring rod 33. A curved rod 352 is fixedly provided on both sides of the collar 351. The ends of the two curved rods 352 are provided with spoon-shaped stirring blades 353 with openings in opposite directions and are fixedly connected. A clamping claw 4 is provided on the side of the gripping handle 1. The X-shaped oblique stirring rod 32 is combined with the horizontal stirring rod 33 to stir the liquid or solid mixture from multiple directions, thereby improving the uniformity and efficiency of stirring. The stirring ball 34 can increase the contact area during the stirring process and further promote the uniform mixing of the mixture. The spoiler component 35 can disrupt the central vortex formed during the stirring process to avoid material accumulation.

[0021] Among them, a touch panel 11 is provided on the outer surface of the gripping handle 1, a charging hole 12 is provided on the top of the gripping handle 1, a battery 13 is provided on the inner side of the gripping handle 1 and is fixed by a snap, a motor 14 is provided at the bottom of the battery 13, the motor 14 is connected to the gripping handle 1 by a snap, a connector 15 is provided at the output end of the motor 14 and is connected, and the other end of the connector 15 is inserted and connected to the transmission rod 2 and fixed by a snap.

[0022] A fixing collar 5 is provided at the bottom of the gripping handle 1 , which is connected to the gripping handle 1 by screws. The fixing collar 5 is limited by a buckle that clamps the outer side of the transmission rod 2 , and a plurality of limiting grooves 51 are provided at equal angles on the outer side of the fixing collar 5 .

[0023] The clamping jaw 4 includes a fixed bracket 41, one end of which is connected to a clamping head 42. The clamping head 42 includes a collet 43 with a retractable bottom design. A number of limit bars 44 are fixed on the inner side of the collet 43. When the gripping handle 1 is placed in the collet 43, the limit bars 44 are inserted into the inner side of the limit groove 51. The combined design of the collet 43 and the limit bars 44 provides an additional fixing effect, which is convenient for users to fix the stirring device on a laboratory bench or other support when using it to prevent it from accidentally slipping.

[0024] Working principle: During use of the present invention, the fixed bracket 41 is connected to the test tube clamp, and when the holding handle 1 is placed in the claw 43, the limit bar 44 is inserted into the inner side of the limit groove 51 for limiting, and the equipment is started. The motor 14 drives the connecting head 15 and the transmission rod 2 to rotate, and the X-shaped oblique stirring rod 32 and the horizontal stirring rod 33 stir the material in the vessel. After the material rushes into the spoon-shaped stirring blade 353, a thrust is formed to make it rotate around the horizontal stirring rod 33. When the X-shaped oblique stirring rod 32 and the horizontal stirring rod 33 rotate rapidly, centrifugal force is generated in the material and a vortex is formed, which attracts the material to the middle and accumulates it, affecting the stirring effect. The rotation direction of the spoon-shaped stirring blade 353 is different from that of the X-shaped oblique stirring rod 32 and the horizontal stirring rod 33, which can interfere with the formation of eddy currents and avoid the formation of vortices.
