[0023] In this embodiment, the magnetic particle machine body 1 belongs to the existing mature technology, and its working principle will not be described here. The storage battery 2 is directly provided on the magnetic particle machine body 1, so that the device can work independently without an external power supply, and has good portability. Through the combined use of the protective shell 7 and the sealing gasket 8, it can effectively prevent liquid from entering the gap between the magnetic particle machine body 1 and the storage battery 2. In this way, when replacing the storage battery 2 later, it is not easy for the liquid to contact the connection between the storage battery 2 and the magnetic particle machine body 1, effectively preventing the corrosion problem caused by liquid infiltration, which is beneficial to extending the service life of the entire device and has a good protection effect. When the storage battery 2 needs to be removed, the moving mechanism can be used to drive the protective shell 7 to move, so that the gap between the storage battery 2 and the magnetic particle machine body 1 can be exposed, and then the storage battery 2 can be removed by pulling it out. The operation is relatively convenient and fast. During the use of this device, in order to prevent the device from falling to the ground when it is separated from the hand, the positioning mechanism can be used to tightly sleeve the bracelet band 4 on the operator's wrist. In this way, when the operator accidentally loosens the device, the device will not fall to the ground, but only hang on the operator's hand, which can effectively ensure the safety of the device.

[0024] In a further preferred embodiment of the present utility model, the moving mechanism includes: a rotating shaft 10 rotatably installed in the cover body 9; two screw rods 11 rotatably installed along the axial direction on the closed end of the protective shell 7, and the two screw rods 11 are respectively threadedly connected to both ends of the support plate 6; two first bevel gears 12 fixedly sleeved on the rotating shaft 10; two second bevel gears 13 respectively fixedly sleeved on the two screw rods 11, and the two second bevel gears 13 are respectively engaged with the two first bevel gears 12.

When in use, the rotating shaft 10 is rotated by hand, and the rotating shaft 10 will drive two first bevel gears 12 to rotate. The two first bevel gears 12 will drive two screw rods 11 to rotate through two second bevel gears 13. Since the two screw rods 11 are threadedly connected to the support plate 6, the rotation of the two screw rods 11 can push the support plate and the protective case 7, so that the protective case 7 and the gasket 8 can be separated from the gap between the storage battery 2 and the magnetic powder machine body 1. After the separation, the operator can remove the storage battery 2 by pulling it upward.

[0026] In a further preferred embodiment of the present utility model, the positioning mechanism includes: a pull rod 14 slidably installed on the inner wall of one side of the installation groove, and one end of the pull rod 14 extends to the outside of the connecting block 5; a spring 15 slidably sleeved on the pull rod 14; a pressing plate 16 fixedly installed on the pull rod 14, and a plug rod 17 fixedly installed on the pressing plate 16, and the plug rod 17 is adapted to any one of the through holes.

After the insertion is completed, the size of the circle formed by the bracelet 4 can be fixed, and the operation is relatively convenient.

[0028] In a further preferred embodiment of the present utility model, one ends of the two screw rods 11 are both fixedly installed with baffles 18, and the two baffles 18 are both circular.

[0029] In this embodiment, by using the baffle 18, it is possible to prevent the screw rod 11 from detaching from the support plate 6 due to excessive movement.

[0030] In a further preferred embodiment of the present utility model, one end of the rotating shaft 10 is fixedly installed with a knob 19, and a plurality of anti-slip sheets are fixedly installed on the knob 19.

[0031] In this embodiment, by the combined use of the knob 19 and the plurality of anti-slip sheets, it is convenient for the operator to rotate the rotating shaft 10 by hand, and it is not easy to slip during the rotation process.

[0032] In a further preferred embodiment of the present utility model, both of the two screws 11 are made of stainless steel, and the bracelet band 4 is made of rubber.

[0035] In this embodiment, through the use of the pull ring, it is convenient for the operator to pull the pull rod 14 by hand, making the pulling operation of the pull rod 14 simple.

[0036] In summary, compared with the related art, through the use of the positioning mechanism in this solution, it is convenient for the operator to adjust and fix the size of the circle formed by the bracelet band 4, so that the bracelet band 4 can be tightly sleeved on the operator's wrist. In this way, when the operator accidentally releases the device, the device will not fall to the ground, but only hang on the operator's hand, which can effectively ensure the safety of the device. Through the combined use of the protective shell 7 and the sealing gasket 8, the gap between the magnetic particle machine body 1 and the storage battery 2 can be effectively blocked, and it can effectively prevent liquid from entering the gap between the magnetic particle machine body 1 and the storage battery 2. In this way, when replacing the storage battery 2 later, it is not easy for the liquid to contact the connection between the storage battery 2 and the magnetic particle machine body 1, effectively preventing the corrosion problem caused by liquid infiltration, which is beneficial to extending the service life of the entire device, and the protection effect is good. Through the use of the moving mechanism, the protective shell 7 can be moved, so that the gap between the storage battery 2 and the magnetic particle machine body 1 can be exposed. After the gap between the storage battery 2 and the magnetic particle machine body 1 is exposed, the storage battery 2 can be removed by pulling it out upwards, and the operation is relatively convenient and fast.
