Figure 3-Figure 4 As shown, after the back side of the lower base plate 204 is inserted into the guide rail 110, the lower base plate 204 can only move along the length direction of the guide rail 110;

[0032] A screw rod 112 is inserted into the inner wall of the installation groove 105. A clamping groove 114 is opened on the side of the screw rod 112 located inside the installation groove 105. The inner sides of the clamping groove 114 are respectively against the two clamping wheels 107.

[0035] The working principle of this utility model:

[0036] The motor rotor 111 can be pre-installed and fixed to the top of the fixed seat plate 109 by bolts. When installing the motor stator 203, first align the plug shaft 104 on the back of the lifting slope 103 and insert it into the socket 102, then push the lower base plate 204, and climb it along the lifting slope 103 to the inside of the motor base 101 with the help of the support wheels 206. The back side of the lower base plate 204 is aligned and snapped into the inside of the guide rail 110 to complete the positioning of the lower base plate 204 and the upper motor stator 203, and then the lifting slope 103 and the fixed seat plate 109 are removed.

[0037] Secondly, after passing the end of the screw 112 with the clamping groove 114 through the motor rotor 111, it is screwed into the internal threaded hole 202, and finally inserted into the installation groove 105, pushing the clamping wheels 107 on both sides, and the bottom end of the screw 112 is inserted into the limit bearing 106.

At this time, the bottom end of the screw 112 is limited in the installation groove 105, and the screw 112 cannot move up and down. At this time, the hand wheel 113 is rotated, and the surface thread of the screw rod 112 pushes the internal thread hole 202, driving the stator shaft 201 and the lower base plate 204 to move upward along the guide rail 110 until the lower base plate 204 contacts the bottom surface of the fixed seat plate 109, and then the lower base plate 204 is fixed to the fixed seat plate 109 by bolts. Finally, the clamping wheel 107 is pushed again to separate from the clamping groove 114, and the screw rod 112 is gradually screwed upward out of the internal thread hole 202 by rotating the hand wheel 113.
