[0008] Furthermore, the positioning assembly includes: a positioning block fixedly mounted on the outside of the motor shaft body, and a positioning groove fixedly arranged on the inside of the connecting ring.

[0009] Furthermore, a slot is provided on the surface of the motor shaft body.

[0010] Furthermore, the spline groove is arranged in an "L" shape.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a motor shaft that is easy to load and unload. By pressing and rotating the limit cap, the spline pin moves to the transverse groove of the spline groove, and the fixing rod extends into the slot to engage with it, so as to fix the motor shaft body and achieve the purpose of quick loading and unloading;

[0012] The purpose of positioning the motor shaft body can be achieved by using the positioning block in conjunction with the positioning slot, so that the fixing rod and the slot are aligned during loading and unloading, thereby improving loading and unloading efficiency.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0020] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. 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 4 As shown, the utility model is a motor shaft that is easy to load and unload, comprising: a connecting ring 1, a motor shaft body 2, a surface of the motor shaft body 2 is provided with a slot 5, a positioning component 3 for positioning the connecting ring 1, and a fixing component 4 for fixing the connecting ring 1;

[0022] The fixing assembly 4 includes: a limiting cap 401 and a sleeve 402 . The sleeve 402 is welded in the connecting ring 1 . A spline groove 404 is fixed on the surface of the sleeve 402 . The spline groove 404 is set in an “L” shape. The setting of the spline groove 404 facilitates the limiting of the fixing rod 403 .

[0023] A telescopic spring 406 is fixedly mounted on the inner wall of the sleeve 402, and the telescopic spring 406 can facilitate the withdrawal of the fixing rod 403 from the slot 5 during disassembly. The fixing rod 403 is fixedly mounted on one end of the limiting cap 401, and a fixing ring 407 is welded and mounted on the surface of the fixing rod 403 near the limiting cap 401. The bottom end surface of the fixing ring 407 is provided with a groove body for the telescopic spring 406 to rotate. A spline pin 405 is fixedly mounted on the surface of the fixing rod 403 away from the limiting cap 401. The fixing rod 403 can be quickly fixed by using the spline pin 405 in conjunction with the spline groove 404.

[0024] In the present invention, by pressing and rotating the limiting cap 401, the spline pin 405 moves into the transverse groove of the spline groove 404, and the fixing rod 403 extends into the clamping groove 5 and engages with it, thereby fixing the motor shaft body 2 and achieving the purpose of quick assembly and disassembly.

[0025] The positioning assembly 3 includes: a positioning block 301 fixedly installed on the outside of the motor shaft body 2, and a positioning groove 302 fixedly arranged on the inside of the connecting ring 1. The inner diameter of the positioning groove 302 is larger than the outer diameter of the positioning block 301. Through the setting of the positioning block 301 and the positioning groove 302, the motor shaft body 2 can be positioned.

[0026] Working principle: During installation, the positioning block 301 is aligned with the positioning groove 302, and the motor shaft body 2 is pushed into the connecting ring 1 until the end face of the positioning block 301 is aligned with the end face of the connecting ring 1, and the rotation limit cap 401 is pressed and the telescopic spring 406 is compressed, and the spline pin 405 moves to the transverse groove of the spline groove 404, and the fixing rod 403 extends into the card slot 5 and engages with it, so as to achieve the purpose of quick loading and unloading. At the same time, through the coordinated use of the positioning block 301 and the positioning groove 302, not only is it convenient to align the fixing rod 403 with the card slot 5 during loading and unloading, but also the motor shaft body 2 can be positioned to improve its installation stability.

[0027] During disassembly, the rotation limit cap 401 is pressed in the opposite direction, the spline pin 405 withdraws from the transverse groove of the spline groove 404, the telescopic spring 406 returns to the initial state, and the fixing rod 403 withdraws from the slot 5, thereby releasing the fixing restriction on the motor shaft body 2 and achieving the purpose of quick disassembly.

[0028] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
