[0002] The main function of the motor shaft is to generate driving torque. As a power source for electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. The shaft is one of the indispensable parts in the use of the motor.

[0003] Prior art, such as patent publication number CN211579779U discloses a motor shaft that is easy to install, including a connecting frame, a first cavity is opened on the left side of the connecting frame, a motor output end is arranged on the left side of the connecting frame, the right end of the motor output end is inserted into the first cavity, and a slot is opened at the top and bottom of the first cavity. The utility model is provided with a through slot, a first compression spring, a plug rod, a slot and a vertical rod, so that when installing, the vertical rod is pulled upward by holding the vertical rod, and the vertical rod drives the plug rod to squeeze the first compression spring and shrink inward, and the motor output end is aligned with the first cavity and inserted, and the vertical rod is stopped at this time. At this time, the elastic potential energy generated by the compression of the first compression spring is released, and the elastic force generated drives the plug rod to be inserted into the slot. At this time, the first cavity is connected to the connecting frame, and the installation and disassembly are relatively convenient, which effectively saves the time of the staff to install and disassemble the device, and is convenient for the staff to operate and use the device.

[0004] In actual use, the motor output end rotates, driving the connecting frame to rotate. However, when the speed is high, the centrifugal force received by the insertion rod is greater than the sum of the elastic forces of the tension spring and the first compression spring, and the insertion rod will gradually slide out of the through slot, separating the motor output end and the connecting frame.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, the utility model is a stably installed motor shaft, including a connecting frame 101, a motor output end 102, a shaft body 103, a limiting component 200 that limits the motor output end 102 and the shaft body 103, and a fixing component 300 that fixes the motor output end 102 and the shaft body 103. A rotating sleeve 104 is threadedly provided on the outer wall of the connecting frame 101.

[0022] The limiting assembly 200 includes a first fixed cavity 203 and a second fixed cavity 204, which are respectively arranged at two ends of the connecting frame 101, and a limiting groove 202 is provided inside the first fixed cavity 203 and the second fixed cavity 204. A limiting block 201 is slidably installed in the limiting groove 202, and the limiting block 201 is fixedly installed on the motor output end 102 and the rotating shaft body 103.

[0023] The fixing assembly 300 includes a slide groove 303, which is symmetrically arranged on the motor output end 102 and the shaft body 103, respectively. A sleeve 301 is slidably installed in the slide groove 303, and a third inclined surface and a fourth inclined surface are arranged on the top of the sleeve 301. The third inclined surface is close to the bottom of the first fixed cavity 203, and the fourth inclined surface is far away from the bottom of the first fixed cavity 203. When the motor output shaft and the shaft body 103 are respectively inserted into or taken out of the first fixed cavity 203 and the second fixed cavity 204, the third inclined surface and the fourth inclined surface can press the sleeve 301 into the slide groove 303 when they contact the cavity opening and the circular groove 304 opening, which is convenient for installation and disassembly. The bottom of the slide groove 303 and the sleeve A fixing spring 302 is fixedly installed between the top of the inner wall 301, and a circular groove 304 aligned with the slide groove 303 is symmetrically provided on the inner wall of the connecting frame 101. An extrusion block 305 is slidably installed in the circular groove 304. The extrusion block 305 is composed of a top pressure rod, a bottom pressure rod and an intermediate circular plate. The rotating sleeve 104 and the extrusion block 305 are provided with a first inclined surface and a second inclined surface parallel to each other on one end passing through the inner wall of the connecting frame 101. The rotating sleeve 104 can be rotated to make the first inclined surface and the second inclined surface contact and squeeze the extrusion block 305. A supporting spring 306 is installed around the extrusion block 305, and the supporting spring 306 is installed between the extrusion block 305 and the top of the inner wall of the circular groove 304.

[0024] In the utility model, the extrusion block 305 is composed of a top pressure rod, a bottom pressure rod and a circular plate. The circular plate prevents the extrusion block 305 from sliding out of the top perforation of the circular groove 304. The third and fourth inclined surfaces on the top of the sliding sleeve 301 are used to press the sliding sleeve 301 into the sliding groove 303 when inserting or removing the motor output end 102 and the rotating shaft body 103. The first inclined surface on the rotating sleeve 104 can contact and squeeze the second inclined surface on the extrusion block 305 after the rotating sleeve 104 rotates, so that the extrusion block 305 squeezes the sliding sleeve 301 and removes the motor output end 102 or the rotating shaft body 103.

[0025] Working principle: Align the limit groove 202 and the limit block 201, insert the motor output end 102 into the first fixed cavity 203, insert the shaft body 103 into the second fixed cavity 204, the third inclined surface on the sleeve 301 contacts the edge of the cavity and is squeezed, so that the sleeve 301 compresses the fixed spring 302 and slides into the slide groove 303. When the sleeve 301 is aligned with the circular groove 304, the top of the sleeve 301 slides into the circular groove 304 and contacts the bottom of the squeezing block 305. When the motor shaft rotates, the sleeve 301 is subjected to the centrifugal force and the top is squeezed. At the bottom of the extrusion block 305, the circular plate on the extrusion block 305 contacts the bottom of the circular groove 304, so that the sliding sleeve 301 cannot be separated from the sliding groove 303. During disassembly, the rotating sleeve 104 is rotated to make the first inclined surface on the rotating sleeve 104 squeeze the second inclined surface on the extrusion block 305, so that the extrusion block 305 squeezes the sliding sleeve 301, and the fourth inclined surface on the sliding sleeve 301 contacts the edge of the notch of the circular groove 304. When the motor output end 102 or the shaft body 103 is pulled out, the sliding sleeve 301 is compressed into the sliding groove 303, and the motor shaft achieves the purpose of stable installation.
