The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and 2, an embodiment of the present invention provides a magnetic-type front maintenance tool 10, which includes a hand piece 100, a screw rod 200, a sleeve 300, a support housing 500, and a magnet 400,

the support housing 500 has a first end surface 500a and a second end surface 500b opposite to each other, a cavity is formed inside the support housing 500, a through hole is formed in the first end surface 500a, and the cavity is communicated with the outside through the through hole; the magnet 400 is disposed in the cavity of the support case 500;

the sleeve 300 is provided with a hollow tube cavity, internal threads are arranged on the tube cavity, the sleeve 300 is fixedly arranged at the through hole of the first end face 500a, and the tube cavity is communicated with the through hole;

the screw rod 200 is provided with external threads, the screw rod 200 passes through the tube cavity of the sleeve 300 and partially extends into the cavity of the support shell 500, and the screw rod 200 is in threaded connection with the sleeve 300;

one end of the screw rod 200 extending into the supporting shell 500 is fixedly connected with the magnet 400, and the other end is fixedly connected with the hand piece 100; when the hand piece 100 is rotated, the hand piece 100 drives the screw rod 200 to rotate, the screw rod 200 moves relative to the sleeve 300, and the screw rod 200 drives the magnet 400 to approach or be away from the second end surface 500b of the support housing 500 in the moving process.

The second end 500b of the support housing 500 is a surface contacting L ED display module during front maintenance, the support housing 500 can be regarded as a mounting frame, and the hand piece 100, the lead screw 200, the sleeve 300 and the magnet 400 are all directly or indirectly fixedly connected with the support housing 500.

The socket 300 is fixed to the support housing 500 at the through hole on the first end surface 500a of the support housing 500, and is fixedly coupled to the support housing 500. The lead screw 200 passes through the lumen of the cannula 300 and is threadedly engaged with the cannula 300. The screw rod 200 is fixedly connected with the hand piece 100, and a user can rotate the screw rod 200 by operating the hand piece 100, so that the screw rod 200 can be driven to move upwards or downwards relative to the sleeve 300. Because the end of the screw rod 200 extending into the supporting housing 500 is connected with the magnet 400, the up-and-down movement of the screw rod 200 can drive the magnet 400 to move up and down relative to the sleeve 300.
