[0026] The present utility model provides a motor spindle drive structure. By setting the slotted, clamping groove, limiting plate, limiting groove, threaded hole and the first bolt, the connecting shaft is installed at the end of the spindle main body far from the motor main body. During actual use, a connecting shaft with a suitable length can be selected for installation according to the actual use situation, so as to facilitate the adjustment of the length of the motor spindle, and thus enhance the practicability of the device.

[0027] Figures 1 - 3 Shown is a structural schematic diagram of an embodiment of a motor spindle drive structure of the present utility model. Please refer to Figures 1 - 3 , A motor spindle drive structure of this embodiment, its main part includes a motor main body 100, a spindle main body 200 and a connecting component 300.

[0028] Motor main body 100. As a preference, in this embodiment, a base 101 is fixed at the lower end of the motor main body 100, and a second bolt 102 is provided on the base 101. The second bolt 102 penetrates through the base 101, and the motor main body 100 is fixedly installed at a designated position under the action of the base 101 and the second bolt 102, so as to ensure the stable placement of the motor main body 100.

[0029] The main shaft body 200 is rotatably arranged in the middle of the end of the motor body 100. On both sides of the middle of the end of the main shaft body 200 away from the motor body 100, there are slots 201. On the slots 201, there are limit slots 202, and through threaded holes 203 are opened on the slots 201.

[0030] The connection component 300 includes a connecting shaft 310 arranged at the end of the main shaft body 200 away from the motor body 100, a clamping slot 320 opened in the middle of the end of the connecting shaft 310, a limiting plate 330 fixed on the inner wall of the clamping slot 320, and a first bolt 340 arranged on the outer wall of the connecting shaft 310. The first bolt 340 penetrates through the connecting shaft 310 into the main shaft body 200, and the first bolt 340 is threadedly connected with the threaded hole 203. Preferably, in this embodiment, an opening 311 is opened on the outer wall of the connecting shaft 310. The first bolt 340 is located in the opening 311. The opening 311 opened on the outer wall of the connecting shaft 310 is used for placing the first bolt 340 to prevent the first bolt 340 from protruding from the connecting shaft 310, facilitating the subsequent installation of the limiting block 204. An external thread is provided on the outer wall of the main shaft body 200, and a limiting block 204 is arranged on the external thread of the main shaft body 200. The limiting block 204 is located outside the connection between the main shaft body 200 and the connecting shaft 310. The limiting block 204 threadedly installed on the outer wall of the main shaft body 200 can limit the first bolt 340 located in the opening 311 of the connecting shaft 310 to prevent the first bolt 340 from slipping. The cross-section of the limiting block 204 is a regular hexagon. The limiting block 204 with a regular hexagon cross-section facilitates subsequent operators to tighten or disassemble it with a wrench or other tools. Lubricating oil is provided on the inner wall of the limit slot 202. The lubricating oil provided on the inner wall of the limit slot 202 lubricates the connection between the limit slot 202 and the limiting plate 330 to prevent wear between the two.

[0031] Combined Figures 1 - 3 , a motor main shaft transmission structure of this embodiment is specifically used as follows: The operator selects a connecting shaft 310 with a suitable length according to the actual usage situation, clamps the clamping slot 320 of the connecting shaft 310 on the end of the main shaft body 200 away from the motor body 100. The provided limiting plate 330 and limit slot 202 limit the connecting shaft 310. Then, the first bolt 340 is installed on the outer wall of the connecting shaft 310. The first bolt 340 penetrates through the connecting shaft 310 into the main shaft body 200, thereby installing the connecting shaft 310 on the main shaft body 200. Finally, the limiting block 204 is rotated, and the limiting block 204 is rotated to the outside of the connection between the main shaft body 200 and the connecting shaft 310, thereby limiting the first bolt 340 located in the opening 311 of the connecting shaft 310 to prevent the first bolt 340 from slipping, ensuring the stable connection of the first bolt 340, and thus ensuring the stable connection between the connecting shaft 310 and the main shaft body 200.

[0032] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
