[0019] Figure 3 It is a structural schematic diagram of a J-shaped groove. DETAILED DESCRIPTION

[0020] The utility model is now further described with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, a fancy twisting spindle includes a hollow spindle rod 1, an upper locking head 2, a lower locking head 3, a bearing seat 5, a connecting seat 71 and a motor 73. The top of the hollow spindle rod 1 is symmetrically provided with two J-shaped grooves 11; the upper locking head 2 is movably inserted in the top of the hollow spindle rod 1, and locking pins 21 are symmetrically installed on both sides of the upper locking head 2. The locking pins 21 are movably inserted in the J-shaped grooves 11 to fix the upper locking head 2 and facilitate the disassembly of the upper locking head 2. The lower locking head 3 is installed on the hollow spindle rod 1 and is located below the upper locking head 2. The upper locking head 2 and the lower locking head 3 are respectively provided with an upper conical surface 22 and a lower conical surface 31. The two ends of the bobbin 9 are respectively inserted into the upper locking head 2 and the lower locking head 3, and are against the upper conical surface 22 and the lower conical surface 31. The conical surface can better press the bobbin 9, increase the contact area with the bobbin 9, and improve the friction force, so as to ensure that the bobbin 9 rotates synchronously with the hollow spindle rod 1. The hollow spindle rod 1 is rotatably mounted on the bearing seat 5; the connecting seat 71 is mounted at the bottom of the bearing seat 5 and connected to the motor 73, and the motor 73 is connected to the hollow spindle rod 1 through a coupling.

[0022] The upper locking head 2 is easy to disassemble and assemble, and is convenient for replacing the bobbin 9, making the fixing structure of the bobbin 9 simpler. The motor 73 is directly connected to the hollow spindle rod 1, and there is no need to set a complex tangential belt transmission structure. The overall structure is simpler and can be independently controlled.

[0023] like Figure 3 As shown, a positioning groove is provided at the tail of the J-shaped groove 11, which can clamp the locking pin 21 to prevent the upper locking head 2 from detaching from the hollow spindle rod 1 when pressing the bobbin 9, thereby ensuring the reliability of the connection of the upper locking head 2.

[0024] In certain embodiments, such as Figure 1 and Figure 2As shown, it also includes: an elastic pressing device, which is arranged between the hollow spindle rod 1 and the lower lock 3, and is used to press the lower lock 3 on the bobbin 9. Among them, the lower lock 3 is movably inserted into the hollow spindle rod 1. Specifically, the elastic pressing device includes a first retaining ring 43, a second retaining ring 42 and a spring 41. The first retaining ring 43 is installed in the installation groove on the hollow spindle rod 1, and the first retaining ring 43 is located above the lower lock 3, which is used to limit the lower lock 3 on the hollow spindle rod 1 to prevent the lower lock 3 from detaching from the hollow spindle rod 1; the second retaining ring 42 is installed in the installation groove on the hollow spindle rod 1, and the second retaining ring 42 is located below the lower lock 3; the spring 41 is movably inserted into the hollow spindle rod 1, and the two ends of the spring 41 are respectively against the lower lock 3 and the second retaining ring 42. The spring 41 can not only press the lower lock head 3 onto the bobbin 9, but also has a large tolerance space, which solves the influence of the height difference of the bobbin 9 on the upper lock head 2 and the lower lock head 3 pressing the bobbin 9. In order to further shorten the overall length, an elastic groove 32 is provided on the lower lock head 3, and the spring 41 is movably inserted into the elastic groove 32, and the end of the spring 41 is against the bottom of the elastic groove 32.

[0025] In certain embodiments, such as Figure 1 and Figure 2As shown, the vibration reduction device 6 is also included, and the vibration reduction device 6 is installed between the bearing seat 5 and the bearing inside the bearing seat 5. Specifically, the vibration reduction device 6 includes an upper vibration absorbing ring 61 and a lower vibration absorbing ring 66. The upper vibration absorbing ring 61 and the lower vibration absorbing ring 66 are both made of rubber, have good elasticity, and can effectively reduce vibration. The upper vibration absorbing ring 61 is provided with an upper fixed groove, and the lower vibration absorbing ring 66 is provided with a lower fixed groove. The upper fixed groove and the lower fixed groove are both annular grooves and match the bearing. The upper vibration absorbing ring 61 and the lower vibration absorbing ring 66 are respectively installed at both ends of the bearing, the upper bearing 51 is installed in the upper fixed groove, the lower bearing 58 is installed in the lower fixed groove, and the hollow spindle rod 1 is installed on the upper bearing 51 and the lower bearing 58. The third retaining ring 63 and the fourth retaining ring 64 are respectively provided at both ends of the upper vibration absorbing ring 61, and the third retaining ring 63 and the fourth retaining ring 64 are both installed in the installation groove of the bearing seat 5 to achieve axial fixation of the upper vibration absorbing ring 61. A shaft shoulder is provided on the hollow spindle rod 1, and the upper bearing 51 is against the shaft shoulder. The hollow spindle rod 1 is also equipped with a fifth retaining ring 55 and a sleeve 54, and the two ends of the sleeve 54 are respectively against the inner ring of the fifth retaining ring 55 and the upper bearing 51 to achieve the axial positioning of the upper bearing 51. In order to prevent the upper vibration absorbing ring 61 from running out of the third retaining ring 63 after being stressed, an anti-expansion ring 62 is also installed between the third retaining ring 63 and the upper vibration absorbing ring 61. The anti-expansion ring 62 increases the contact area between the upper vibration absorbing ring 61 and prevents the upper vibration absorbing ring 61 from running out of the third retaining ring 63 after being squeezed, thereby improving the reliability of the fixation of the upper vibration absorbing ring 61. The two ends of the lower bearing 58 are respectively fixed to the hollow spindle rod 1 through the sixth retaining ring 56. The upper vibration absorbing ring 61 and the lower vibration absorbing ring 66 can not only ensure the amplitude of the end of the upper hollow spindle rod 1, but also ensure the overall stability and use accuracy, and ensure the service life. The whole set of spindles runs particularly stably and with low noise.
