Referring to fig. 1 to 4, the utility model provides a high stability test-tube rack. This high stability test-tube rack includes: support body 1 and fixed subassembly 2, be equipped with a plurality of holes 11 of placing on the support body 1, place hole 11 and be used for placing the test tube. The fixing component 2 is fixedly connected with the frame body 1, and the frame body 1 is provided with an avoiding space corresponding to the fixing component 2; the fixing assembly 2 can fix the frame body 1. The fixing assembly 2 comprises: two soft irons 21, a permanent magnet 23 and a trigger bar 24 which are oppositely arranged. Brass 22 is arranged between the two pieces of soft iron 21 which are oppositely arranged, and the soft iron 21 is fixedly connected with the frame body 1; the permanent magnet 23 is located two the middle part of soft iron 21, soft iron 21 embraces and connects permanent magnet 23, permanent magnet 23 rotates to be connected support body 1, and the both sides of permanent magnet 23 are equipped with the pivot, and the pivot rotates to be connected support body 1. When the permanent magnet 23 is in the vertical direction, each end of the permanent magnet 23 is connected with two soft irons 21; when the permanent magnet 23 is in the horizontal direction, each end of the permanent magnet 23 is only contacted with one soft iron 21, and the soft irons 21 contacted with the two ends of the permanent magnet 23 are not the same soft iron 21; the trigger rod 24 is slidably connected with the frame body 1, and the trigger rod 24 controls the rotation of the permanent magnet 23. The movement or rotation of the trigger lever 24 realizes the rotation of the permanent magnet 23, thereby controlling the permanent magnet 23 to be in different positions and controlling the generation and disappearance of magnetic force. Fixed subassembly 2 is located the below of support body 1, has increased the dead weight of support body 1, and support body 1's stability is better. Meanwhile, the generation and disappearance of the magnetic force can be controlled, so that the use is more convenient. The workstation desktop that this high stability test-tube rack corresponds is the magnetic conduction material for fixed subassembly 2 can magnetism inhale on the workstation.

As a preferred embodiment of the utility model, the both sides of permanent magnet 23 are equipped with the pivot, and the pivot is rotated and is connected support body 1, and the trigger bar 24 is through pivot fixed connection permanent magnet 23, and the trigger bar 24 is located the outside of support body 1, through rotatory trigger bar 24, realizes permanent magnet 23's rotation for permanent magnet 23 and soft iron 21's different positions contact, realize magnetic force's production and disappearance. When the magnetic force is generated, the frame body 1 is magnetically attracted on the workbench, and when the magnetic force disappears, the frame body 1 can move.

As another preferred embodiment of the present invention, the two ends of the permanent magnet 23 are provided with a gear 231, the gear 231 is fixedly connected to the rotating shaft, and the triggering rod 24 corresponds to the gear 231 is provided with a rack structure 241. When the trigger lever 24 slides relative to the frame body 1, the rack structure 241 on the trigger lever 24 rotates the gear 231, so that the permanent magnet 23 rotates, the rotation of the permanent magnet 23 is realized, the permanent magnet 23 contacts with different positions of the soft iron 21, and the generation and disappearance of magnetic force are realized. When the magnetic force is generated, the frame body 1 is magnetically attracted on the workbench, and when the magnetic force disappears, the frame body 1 can move.

Further, the fixed assemblies 2 have multiple sets, multiple sets of the fixed assemblies 2 are arranged side by side, and one trigger rod 24 controls the rotation of all the permanent magnets 23.
