In the figure, a hollow shaft motor 1, a fixed disc 2, a convex column 3, a threaded hole 4, a necking 5, a screw rod 6, an inserting column 7, a ball ring 8, a handle 9, an inserting block 10, a column groove 11 and a magnet 12.

Detailed Description

In order to clearly understand the technical features, objects and advantageous effects of the present invention, the technical solutions of the present invention will be described in detail below, but the present invention is not limited to the practical scope of the present invention.

As shown in the figure, the hollow shaft motor with the external rotating shaft capable of being detached easily comprises a hollow shaft motor 1, a fixed disc 2, a convex column 3, a threaded hole 4, a necking 5, a screw rod 6, an inserted column 7, a ball ring 8, a handle 9, an inserted block 10, a column groove 11 and a magnet 12, wherein a rotor shaft of the hollow shaft motor 1 is hollow; the fixed disc 3 is provided with a convex column 4, and a threaded hole 4 which is through from front to back is formed in the center of the convex column 4; the fixed disc 3 is fixed at the tail of the hollow shaft motor 1, and the threaded hole 4 is opposite to the hollow shaft; the screw 6 is matched with the threaded hole 4, the front end of the screw 6 is provided with an insert column 7, the end face of the screw 6 at the periphery of the insert column 7 is provided with a ball ring 8, the ball ring 8 converts the sliding friction between the screw 6 and an insert block 10 into rolling friction, the friction coefficient is reduced, the rotating screw 6 is lighter, and the tail part of the screw 6 is provided with a handle 9; a column groove 11 is formed in the inserting block 10, and a magnet 12 is fixed at the bottom of the column groove 11; insert 10 the piece and install on inserting post 7, magnet 12 adsorbs and inserts post 7, avoids inserting piece 10 and drops naturally.

The utility model discloses in, in considering to grab and hold 9 difficult insert screw rod 6 screw hole 4 in, so 4 end departments of screw hole are equipped with into hourglass hopper-

shaped throat

5, and 6 ends of screw rod can slide in screw hole 4 in being in throat 5.

The utility model discloses in, insert post 7 and magnet 12 when considering rotating screw 6 and have the friction, magnet 12 has the damage, so magnet 12 does not have direct contact with inserting post 7, has the interval between the two.

The utility model discloses in, consider that the inserted block 10 diameter is too big, can damage the screw thread in the screw hole 4 when passing through screw hole 4, so the diameter of inserted block 10 slightly is less than the diameter of screw rod 6.

The utility model discloses in, consider that screw rod 6 is when outwards pushing up external pivot, partly be in the quill shaft, in order to avoid the quill shaft to have the friction with screw rod 6, damage the screw thread, so the diameter of screw hole 4 slightly is less than the internal diameter of quill shaft, and the diameter of screw rod 6 will be less than the diameter of quill shaft simultaneously, avoids screw rod 6 and quill shaft to have the friction.

When the external rotating shaft is disassembled, the screw rod is screwed into the threaded hole, and the screw rod is rotated until the external rotating shaft is ejected out of the hollow shaft.

Although the present invention has been described in detail with reference to the foregoing examples, it will be apparent to those skilled in the art that various changes and modifications can be made in the embodiments described above, or equivalent changes and modifications can be made to some of the technical features of the embodiments described above, and any changes, equivalents, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
