The electromagnet 8 is started by the control switch 9. The magnetic force generated by the electromagnet 8 adsorbs the magnetic metal plate 10, so that the magnetic metal plate 10 can be firmly adsorbed on the electromagnet 8. The magnetic metal plate 10 drives the right-angle clamp 6 to be close to the instrument 7. The right-angle positioning plate 2 cooperates with the right-angle clamp 6, so that the instrument 7 can be stably positioned and clamped in multiple directions. When disassembling, the control switch 9 cuts off the power to the electromagnet 8, and the reset mechanism pulls the right-angle clamp 6 to reset, thereby releasing the limit of the right-angle clamp 6 on the instrument 7, completing the disassembly of the instrument 7. The operation is simple and convenient. Compared with the existing screw structure, the device can quickly and conveniently position and clamp the instrument 7, effectively improving the convenience of using the positioning and clamping device.

[0030] Working principle: when clamping, place the instrument 7 on the workbench 1 so that one corner of the instrument 7 is in close contact with the right-angle positioning plate 2, and start the electromagnet 8 by controlling the switch 9. The magnetic force generated by the electromagnet 8 adsorbs the magnetic metal plate 10, so that the magnetic metal plate 10 can be firmly adsorbed on the electromagnet 8. The magnetic metal plate 10 drives the right-angle clamp 6 to be close to the instrument 7. The right-angle positioning plate 2 cooperates with the right-angle clamp 6, so that the instrument 7 can be stably positioned and clamped in multiple directions. When disassembling, the control switch 9 cuts off the power to the electromagnet 8, and the reset mechanism pulls the right-angle clamp 6 to reset, so as to release the limit of the right-angle clamp 6 on the instrument 7, and completes the disassembly of the instrument 7. The operation is simple and convenient.
