The entire contents of this application are incorporated herein by reference. TECHNICAL FIELD The present invention relates to the field of textile machinery, and in particular to a false twister spindle and a false twister. BACKGROUND OF THE INVENTION A false twister spindle is a major component of a false twister. It not only serves to support the friction disc, but also drives the friction disc to rotate to achieve the purpose of rubbing the chemical fiber. 1 is a cross-sectional view of a prior art false twister spindle including a mandrel 1 and a bearing 2 surrounding the mandrel 1. At the end of the mandrel 1 there is provided a transmission member 3 spaced apart from the bearing 2, in which the mandrel 1 drives the other spindles through the transmission member 3. An electric motor 4 is disposed between the transmission member 3 and the bearing 2, and the electric motor 4 and the transmission member 3 are spaced apart from each other in the axial direction of the mandrel 1, and the electric motor 4 supplies power to the spindle shaft. Specifically, the rotor 5 of the motor 4 radially surrounds the mandrel 1 along the mandrel 1 and is connected to the mandrel 1, the stator 6 is connected to the outer casing 7 of the motor 4, and the coil is wound on the stator 6, and the rotor 5 and the stator 6 are along the core. The shafts 1 are spaced apart from each other in the radial direction. The relative rotation of the rotor 5 and the stator 6 effects the conversion of mechanical energy and electrical energy, thereby driving the mandrel 1 to rotate circumferentially. The motor housing 7 has a connecting ring 8 connected to the bearing outer ring 9, which surrounds the bearing 2 in the radial direction of the mandrel 1 and is connected to the bearing outer ring 9. When the false twister spindle is mounted to the base seat of the false twister device, one end of the mandrel 1 without the transmission member 3 first enters the base seat hole, and then the bearing 2 enters the base seat hole. However, since the outer diameter of the connecting ring 8 is larger than the outer diameter of the bearing outer ring 9, that is, the connecting ring 8 protrudes from the outer circumferential surface of the bearing outer ring 9, the bearing 2 can only partially enter the base seat hole, and the connecting ring 8 blocks the false twister The spindle is further inserted into the base seat of the false twist device. Therefore, it is necessary to redesign the base hole of the false twister to accommodate the installation of the false twister spindle. SUMMARY OF THE INVENTION The problem addressed by the present invention is that the connecting ring blocks the false twister spindle from being inserted into the base seat of the false twist device in the axial direction of the mandrel. In order to solve the above problems, the present invention provides a false twister spindle including a mandrel, a bearing surrounding the mandrel, and an electric motor that rotates in a circumferential direction on the bearing side of the bearing; The bearing includes a bearing outer ring radially surrounding the mandrel; the outer casing of the motor has a connecting ring connected to the outer ring of the bearing; the outer ring of the bearing is divided into at least a first portion and a second portion in an axial direction, The outer diameter of the second portion is the maximum outer diameter of the outer ring of the bearing, the connecting ring is sleeved on the first portion and the outer diameter of the connecting ring is not greater than the outer diameter of the second portion.
