[0010] Optionally, an elastic member is sleeved on the screw rod, and the nut cooperates with the bottom of the installation groove to clamp or release the elastic member.

[0011] By adopting the above technical solution, when the electromagnet is adsorbed to the magnetic plate, the nut and the bottom of the mounting groove cooperate to squeeze the elastic part; when the electromagnet is demagnetized, the nut and the bottom of the mounting groove cooperate to release the elastic part, and the elastic part provides elastic force to the nut, so that the mounting base connected by the screw and the electromagnet thereon are quickly separated from the magnetic plate, thereby preventing friction between the electromagnet and the magnetic plate.

The mounting seat 4 is abutted on the lifting member 3 that passes through the adjusting channel 2, and the mounting seat 4 is used to install the electromagnet 5. By adjusting the length of the channel opening through which the lifting member 3 passes, the distance between the mounting seat 4 and the adjusting seat 1 is adjusted, so that the spacing between the electromagnet 5 on the mounting seat 4 and the magnetic suction plate meets the production requirements.

The adjusting screw 7 includes a nut 71 and a screw rod 72. The nut 71 can slide in the mounting groove 6. The bottom of the mounting groove 6 is hollow to form a through-channel 8. The screw rod 72 is passed through the through-channel 8. One end of the screw rod 72 away from the nut 71 is threadedly connected to the adjusting seat 1. An elastic member 9 is sleeved on the screw rod 72. The elastic member 9 is preferably a spring. The nut 71 cooperates with the bottom of the mounting groove 6 to clamp or release the elastic member 9. When the lifting member 3 adjusts the installation height of the mounting seat 4, the mounting seat 4 drives the adjusting screw 7 to move relative to the adjusting seat 1 to adapt to the installation height setting of the mounting seat 4, so that the mounting seat 4 can be stably connected to the adjusting seat 1. When the electromagnet 5 is attracted to the magnetic plate, the nut 71 and the bottom of the mounting slot 6 cooperate to squeeze the elastic member 9; when the electromagnet 5 is demagnetized, the nut 71 and the bottom of the mounting slot 6 cooperate to release the elastic member 9, and the elastic member 9 provides elastic force to the nut 71, so that the mounting base 4 connected to the screw 72 and the electromagnet 5 thereon are quickly separated from the magnetic plate to prevent the electromagnet 5 from rubbing against the magnetic plate.
