The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 4 As shown, the utility model is a plug-in motor shaft, including a plug-in motor shaft, including: an output shaft 102, an output shaft 104, a connecting sleeve 103, a rotating sleeve 105, a positioning assembly 200, a supporting assembly 300, and a fixing assembly 400, and the output shaft 102 is fixedly mounted on the driving motor 101.

[0023] The positioning assembly 200 includes a first limiting groove 201 and a second limiting groove 203. The first limiting groove 201 is symmetrically arranged on the inner wall of the end surface of the connecting sleeve 103 close to the output shaft 102, and a first sliding block is slidably installed in the first limiting groove 201. The second limiting groove 203 is symmetrically arranged on the inner wall of the end surface of the connecting sleeve 103 close to the output shaft 104, and a second sliding block is slidably installed in the second limiting groove 203.

[0024] The fixing assembly 400 includes a first keyway 406 and a second keyway 407, wherein the first keyway 406 is symmetrically arranged on the output shaft 102, and the second keyway 407 is symmetrically arranged on the output rotating shaft 104, a first fixing key 401 is slidably installed in the first keyway 406, and a second fixing key 408 is slidably installed in the second keyway 407, the lower ends of the connecting rod 402 are symmetrically fixedly installed at both ends of the top of the first fixing key 401 and the second fixing key 408, the upper end of the connecting rod 402 passes through the fixing sleeve 403 to be fixedly connected to the movable plate 404, the fixing sleeve 403 passes through and is fixedly installed in the inner wall of the connecting sleeve 103, a supporting spring 405 is installed around the connecting rod 402, and the supporting spring 405 is fixedly installed between the movable plate 404 and the bottom of the inner wall of the fixing sleeve 403.

[0025] The support assembly 300 includes a sleeve 301, which is fixedly installed on the inner wall of the connecting sleeve 103. A support slide bar 302 is slidably installed in the sleeve 301, and the lower ends of the support slide bar 302 are fixedly connected to the tops of the first fixed key 401 and the second fixed key 408 respectively.

[0026] The inner wall surface of the rotating sleeve 105 is composed of an inclined surface, an arc surface and a threaded surface. The rotating sleeve 105 is threadedly arranged on the outer wall of the connecting sleeve 103. The length of the rotating sleeve 105 is greater than the distance between the two movable plates 404. The arc surface of the rotating sleeve 105 is used to fix the movable plate 404, the inclined surface is used to squeeze the movable plate 404, and the threaded surface enables the rotating sleeve 105 to move on the outer wall of the connecting sleeve 103. The rotating sleeve 105 can simultaneously fix the movable plates 404 at both ends of the connecting sleeve 103.

[0027] In the utility model, the inner wall surface of the rotating sleeve 105 is composed of an inclined surface, an arc surface and a threaded surface. The inclined surface is used to press the movable plate 404. The fixed key is inserted into the keyway through the connecting rod 402 so that the outer wall of the movable plate 404 contacts the arc surface to fix the movable plate 404. The arc surfaces at both ends of the inner wall of the rotating sleeve 105 can simultaneously fix the movable plates 404 at both ends of the connecting sleeve 103. The rotating sleeve 105 moves on the outer wall of the connecting sleeve 103 by threaded rotation. When the rotating sleeve 105 rotates and moves toward one end of the connecting sleeve 103, the movable plate 404 at the other end of the connecting sleeve 103 will be separated from the fixation of the arc surface and will be ejected by the supporting spring 405, so that the connecting rod 402 connected to the movable plate 404 drives the fixed key to be separated from the keyway.

[0028] Working principle: During installation, align the first limiting groove 201 and the first limiting block 202, insert the output shaft 102 into the connecting sleeve 103 and press against the fixed plate 106, rotate the rotating sleeve 105, move the rotating sleeve 105 to the end of the connecting sleeve 103 close to the output shaft 102, and the inclined surface of the rotating sleeve 105 presses the movable plate 404. The movable plate 404 compresses the supporting spring 405 and drives the connecting rod 402 to insert the first fixed key 401 into the first key groove 406, align the second limiting groove 203 and the second limiting block 204, and insert the output shaft 104 into the connecting sleeve 103. The connecting sleeve 103 is pressed against the fixed plate 106, and the rotating sleeve 105 is rotated to move the rotating sleeve 105 toward one end of the connecting sleeve 103 close to the output rotating shaft 104. The movable plate 404 at the other end of the connecting sleeve 103 is fixed by the cooperation of the inclined surface and the arc surface on the rotating sleeve 105, so that the second fixed key 408 is inserted into the second key groove 407. The arc surface on the rotating sleeve 105 simultaneously fixes the movable plates 404 at both ends of the connecting sleeve 103, so that the output shaft 102 and the output rotating shaft 104 are fixed. The motor shaft achieves the purpose of facilitating disassembly and installation and improving installation efficiency.
