DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.

[0016] As Figure 1 and Figure 2 shown, a nested doubling spindle includes a spindle base 1. Bearings are installed in the spindle base 1. The bearings include an upper bearing 2 and a lower bearing 3. The upper bearing 2 and the lower bearing 3 are respectively installed at the upper end and the lower end of the spindle base 1. A spindle shaft 4 is inserted through the bearings. A driving wheel 5 is installed on the spindle shaft 4. The driving wheel 5 is arranged in the spindle base 1. A connection hole is formed on the side of the spindle base 1 to facilitate the belt to pass through the connection hole and be connected to the driving wheel 5. A spindle disk 6 is connected to the spindle shaft 4. A spindle disk support seat 7 is arranged below the spindle disk 6. Fixing screws are connected to the periphery of the spindle disk support seat 7. A fixing groove 8 is machined on the spindle shaft 4. The end of the fixing screw is snapped into the fixing groove 8 to fix the spindle disk 6.

[0017] Above the said bobbin disc 6, there is a yarn sleeve 9 sleeved on the spindle 4. The yarn sleeve 9 is used to wind sisal yarn. An installation hole is provided at the upper end of the spindle 4. A push rod 10 is arranged in the installation hole. A plurality of positioning pin holes are evenly distributed around the installation hole. A retaining pin 11 is arranged in the positioning pin hole. In this embodiment, three layers of retaining pins 11 are provided, with four retaining pins in each layer. The four retaining pins 11 are evenly distributed on the spindle 4. The end of the retaining pin 11 is connected with a roller 12 through a shaft. A conical body 13 is machined on the push rod 10. The side of the conical body 13 contacts the roller 12. The upper end of the installation hole is provided with a push rod seat 14. The periphery of the push rod seat 14 is connected with the spindle 4 by screws. A guide hole is machined at the lower end of the push rod seat 14. The push rod 10 extends into the guide hole 15. A control screw 16 is threadedly connected to the upper end of the push rod seat 14. The control screw 16 extends into the guide hole 15 and contacts the upper end of the push rod 10. By screwing the control screw 16 to squeeze the push rod 10, the conical body 13 on the push rod 10 contacts and squeezes the roller 12, so that the retaining pin 11 extends out to fix the yarn sleeve.

[0018] A spring 17 is arranged between the lower end of the push rod 10 and the bottom of the installation hole. After loosening the control screw 16, the spring 17 jacks up the push rod to separate the conical body 13 from the roller 12. In this embodiment, a guide post 18 is arranged at the bottom of the push rod 10. The spring 17 is sleeved on the guide post 18. A return spring 19 is arranged in the installation hole. The return spring 19 is sleeved on the retaining pin 11. A boss is arranged on the retaining pin 11 to block the return spring 19. In this way, after the conical body 13 is separated from the roller 12, the return spring 19 makes the retaining pin 11 retract towards the installation hole of the spindle, so as to facilitate the removal of the yarn sleeve 9 from the spindle 4.

[0019] Bearing covers 20 are installed at the upper and lower ends of the spindle base 1, and the bearing covers 20 press the bearings.

[0020] The present utility model is not limited to the described embodiments. Those skilled in the art can still make some corrections or changes without departing from the spirit and the disclosed scope of the present utility model. Therefore, the scope of the right protection of the present utility model shall be subject to the scope defined by the claims.
