DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0027] See also Figure 1 - Figure 7A novel screw dragon fixing device includes a shell 1, a rotating rod 3 is rotatably connected inside the shell 1, and a fitting wheel 15 is abutted near the rear end of the rotating rod 3. There are four groups of fitting wheels 15 in a circular array outside the rotating rod 3. A fixed shaft 14 is rotatably connected inside the fitting wheel 15. The two ends of the two groups of fixed shafts 14 near the top are fixedly connected to a pressing plate 13. The top of the pressing plate 13 is fixedly connected to a lower pressure rod 9. The lower pressure rod 9 is designed in an inverted "L" shape. A fixing rod 10 is fixedly connected to the outer side of the lower pressure rod 9 near the bottom. There are eight fixing rods 10 in a rectangular array outside the lower pressure rod 9 near the front. On both sides of the back, a lifting block 11 is engaged with the opposite side of the lower pressure rod 9, and the lifting block 11 is slidably connected to the outside of the lower pressure rod 9. A pushing component is arranged at the bottom of the lifting block 11, and the pushing component includes a spring 12. The spring 12 is fixedly connected to the bottom of the lifting block 11 near the center position, and the bottom of the spring 12 is fixedly connected to the engaging box 8. A pressing component is arranged at the top of the lifting block 11, and the pressing component includes a pressing block 18. The pressing block 18 abuts against the top of the lifting block 11. An eccentric rotating shaft 19 is fixedly connected to the front and rear sides of the pressing block 18 near the top position, and the eccentric rotating shaft 19 near the front end is threadedly connected to the front of the engaging box 8. The eccentric rotating shaft 19 near the rear end is rotatably connected to the rear of the locking box 8. During operation, when the rotating rod 3 is fixed, the rotating rod 3 is first prevented from being on the surface of the fitting wheel 15 near the bottom. At this time, the eccentric rotating shaft 19 is rotated again to press the lower pressing block 18 down on the top of the lifting block 11. The fixing rod 10 is pulled by the lifting block 11, thereby driving the lower pressing rod 9 downward, and the fixing rod 10 will give the downward pressure to the pressing plate 13 and the fixing shaft 14. The fixing shaft 14 will transmit the downward pressure to the fitting wheel 15. At this time, the fitting wheel 15 near the top will first contact the top of the rotating rod 3. At this time, continuing to rotate will make the fitting wheel 15 near the top The pressing force of the fitting wheel 15 is greater, thus achieving the effect of fixing the rotating rod 3. When the rotating rod 3 rotates during use, the fitting wheel 15 fits with the rotating rod 3 to make the rotating rod 3 rotate more smoothly. When the rotating rod 3 rotates, the fitting wheel 15 will rotate with the rotating rod 3. When the rotating rod 3 needs to be replaced, it is only necessary to rotate the eccentric rotating shaft 19 in the opposite direction to allow the pressing block 18 to leave the top of the lifting block 11. At this time, the spring 12 will push the fixing rod 10 to move the fixing rod 10 upward. At this time, the fitting wheel 15 will detach from the surface of the rotating rod 3, so that the rotating rod 3 can be taken out from between the fitting wheels 15.

[0028] The eccentric rotating shaft 19 near the rear end is fixedly connected with a pressing handle 20 on the outside, and the two ends of the fixed shaft 14 near the bottom are fixedly connected with brackets 16, and the brackets 16 are fixedly connected to the top of the card box 8. The pressing rod 9 is slidably connected to the top of the card box 8 near the left and right sides, and the outside of the eccentric rotating shaft 19 is fixedly connected with a ratchet gear 21 near the rear end, and the outside of the ratchet gear 21 is engaged with a card block 22 near the right side, and the inner side of the card block 22 is rotatably connected with a support shaft 23 near the top position. The support shaft 23 is fixedly connected to the rear end of the card box 8 near the top position, and the left side of the support shaft 23 abuts against a limiting block 24, and the limiting block 24 is fixedly connected to the rear end of the card box 8 near the top position, and the rear end of the rotating rod 3 is fixedly connected with a motor 5, and the rear end of the motor 5 is fixedly connected with a support plate 6, and the front end of the support plate 6 is fixedly connected with a connecting plate 7 near the bottom position, and the connecting plate 7 is fixedly connected to the rear end of the card box 8 near the bottom position, and the bottom of the shell 1 is fixedly connected with a support block 2, and there are two groups of support blocks 2 that are symmetrical front and back The eccentric rotating shaft 19 is arranged in a shape, and the transmission plate 4 is fixedly connected to the outside of the rotating rod 3. The transmission plate 4 is arranged in a spiral shape. When working, the ratchet gear 21 is rotated by the eccentric rotating shaft 19 driven by the downward pressing handle 20, and the eccentric rotating shaft 19 is released after the locking block 22 blocks the rotation of the ratchet gear 21. When the eccentric rotating shaft 19 drives the pressing block 18 to reach the specified position, the eccentric rotating shaft 19 is released. At this time, the locking block 22 will rely on the limit block 24 to lock the ratchet gear 21, so as to avoid the eccentric rotating shaft 19 from reversing after the downward pressing handle 20 is released, resulting in insufficient downward pressure on the pressing rod 9 and loosening. During operation, the rotating rod 3 drives the transmission plate 4 to rotate inside the shell 1, so as to transport the raw materials to be transmitted. At this time, the effect of equipment use is achieved. When the rotating rod 3 needs to be disassembled, the locking block 22 can be removed from the fitting position of the ratchet gear 21 first, so that the eccentric rotating shaft 19 can be reversed, so that the pressing block 18 can be separated from the top of the lifting block 11, thus achieving the effect of disassembling the rotating rod 3.

[0029] When the utility model is in use, when fixing the rotating rod 3, the rotating rod 3 is first placed on the surface of the bonding wheel 15 near the bottom, and then the eccentric rotating shaft 19 is rotated to make the lower pressing block 18 press down on the top of the lifting block 11, and the fixing rod 10 is pulled by the lifting block 11, thereby driving the lower pressing rod 9 downward, and the fixing rod 10 will give the downward pressure to the pressing plate 13 and the fixing shaft 14, and the fixing shaft 14 will transmit the downward pressure to the bonding wheel 15, and at this time, the bonding wheel 15 near the top will first contact with the top of the rotating rod 3 , then continue to rotate to make the pressing force of the fitting wheel 15 near the top greater, thus achieving the effect of fixing the rotating rod 3, and when the rotating rod 3 is in use, the fitting wheel 15 fits with the rotating rod 3 to make the rotating rod 3 rotate more smoothly, and when the rotating rod 3 rotates, the fitting wheel 15 will rotate with the rotating rod 3, and when the rotating rod 3 needs to be replaced, it is only necessary to rotate the eccentric rotating shaft 19 in the opposite direction to make the pressing block 18 leave the top of the lifting block 11, and then the spring 12 will push the fixing rod 10 to make the fixing rod 10 moves upward, and the fitting wheel 15 will be separated from the surface of the rotating rod 3, so that the rotating rod 3 can be taken out from between the fitting wheels 15. When the eccentric rotating shaft 19 is driven by pressing the handle 20 downward, the rotating ratchet gear 21 will rotate along with the eccentric rotating shaft 19. At this time, the locking block 22 will not block the rotation of the ratchet gear 21. When the eccentric rotating shaft 19 drives the pressing block 18 to reach the specified position, the eccentric rotating shaft 19 is released. At this time, the locking block 22 will rely on the limit block 24 to lock the ratchet gear 21 to prevent it from being released. After the handle 20 is pressed down, the eccentric rotating shaft 19 is reversed, resulting in insufficient downward pressure of the pressing rod 9 and loosening. During operation, the rotating rod 3 drives the transmission plate 4 to rotate inside the shell 1, thereby transporting the raw materials to be transported. At this time, the effect of equipment use is achieved. When the rotating rod 3 needs to be disassembled, the locking block 22 can be removed from the engagement of the ratchet gear 21 first, so that the eccentric rotating shaft 19 can be reversed, allowing the pressing block 18 to detach from the top of the lifting block 11, thereby achieving the effect of disassembling the rotating rod 3.
