Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, a mounting hole connected to the inner cavity of the base 1 is provided at the bottom of the base 1, and the mounting assembly 2 includes an active rod 201 rotatably connected to the inner side wall of the mounting hole through a bearing. A hexagonal groove is provided at the bottom of the active rod 201, and the hexagonal groove can cause the active rod 201 to rotate by using a special tool. A driving bevel gear 202 is fixed to the outer surface of the active rod 201, and a stabilizing rod 204 is rotatably connected to the left side wall of the inner cavity of the base 1 through a bearing. The stabilizing rod 204 can ensure that the driving bevel gear 202 and the driven bevel gear 203 are stably engaged. A driven bevel gear 203 meshing with the driving bevel gear 202 is fixed to the outer surface of the stabilizing rod 204. The cooperation between the driving bevel gear 202 and the driven bevel gear 203 can cause the power direction to change, thereby improving the space utilization rate. The outer surface of the stabilizing rod 204 is provided with a stabilizing portion 205 that passes through the right side wall of the inner cavity of the base 1.

[0032] It should be further explained that the stabilizing portion 205 includes a driving gear 2051 fixed to the outer surface of the stabilizing rod 204 and located on the left side of the driven bevel gear 203. The right side wall of the inner cavity of the base 1 is rotatably connected to six threaded rods 2052 that penetrate to the outside of the left side wall of the base 1 through a bearing. The outer surface of each threaded rod 2052 and located in the base 1 are fixed with a driven gear 2053 that meshes with the driving gear 2051. The driving gear 2051 drives the six driven gears 2053 at the same time, which can cause the six threaded rods 2052 to rotate at the same time. The diameter of the driving gear 2051 is larger than that of the driven gear 2053, which can expand the transmission ratio and improve the installation speed. The outer surface of each threaded rod 2052 and the outer side of the base 1 are fixed with an external thread strip, and the left side of each threaded rod 2052 is provided with a chamfer. The outer surface of each threaded rod 2052 and the outer side of the base 1 are fixed with an external thread strip, and the left side of each threaded rod 2052 is provided with a chamfer.

[0033] It can be known that the limit frame 3 includes two fixing rods 301 fixed to the right side wall of the base 1 and respectively located on the upper and lower sides of the control component 4. The two fixing rods 301 can provide sufficient position for the knob 402, so that the user can turn the knob 402. The outer surface of the stabilizing cylinder 403 is fixed with a limit ring 302. The left side of the limit ring 302 is fixed to the two fixing rods 301. The right side of the limit ring 302 is fixed with two limit rods 303 extending into the docking joint 7. The limit rods 303 can limit the docking joint 7 to prevent the docking joint 7 from rotating.

[0034] In addition, the control component 4 is composed of a connecting ring 401, a knob 402 and a stabilizing cylinder 403. The connecting ring 401 is fixed to the left side wall of the base 1, and the opposite sides of the connecting ring 401 and the stabilizing cylinder 403 extend into the knob 402 and are rotatably connected to the knob 402. The outer surface of the stabilizing cylinder 403 is fixed to the inner side of the limit frame 3, and the right side of the stabilizing cylinder 403 abuts against the docking joint 7. The inner side of the knob 402 is movably connected with a positioning pin that extends into the base 1 and is movably connected to the base 1. A plurality of positioning grooves that are compatible with the positioning pin are provided on the left side of the base 1, and the plurality of positioning grooves are arranged in a ring shape as a whole. This can ensure that after the length is adjusted, the positioning pin can still be reinserted into the base 1 to achieve positioning and limit the knob 402.

[0035] In this embodiment, during installation, only the active rod 201 needs to be rotated to cause the six threaded rods 2052 to rotate simultaneously, thereby improving installation efficiency. At the same time, the chamfers provided on the threaded rods 2052 can improve the convenience of positioning.

[0036] Please refer again Figure 1 and Figures 3 to 5 In order to improve the support stability, the telescopic component 5 in this embodiment includes a connecting tube 501 fixed to the right side wall of the knob 402 and rotatably connected to the outer surface of the transmission shaft 602. A sun gear 502 is fixed to the outer surface of the connecting tube 501. Four planetary gears 504 are meshed on the outer surface of the sun gear 502. The sun gear 502 drives the four planetary gears 504 to rotate. At the same time, the stabilizing effect of the internal teeth can achieve a larger transmission ratio, and the torque is increased by reducing the rotation speed. The inner side of each planetary gear 504 is rotatably connected to a planetary rod 503 through a bearing. A plane bearing 508 is fixed to the left side of the four planetary rods 503. The other end of the plane bearing 508 is fixed to the right side wall of the knob 402. The connecting tube The outer surface of 501 is rotatably connected to a driving disk 505 located on the right side of the sun gear 502 through a bearing. The driving disk 505 can transmit the revolution power of the planetary gear 504 to the output tube 506. Each planet rod 503 penetrates the driving disk 505 and is rotatably connected to the driving disk 505. An output tube 506 is fixed on the right side of the driving disk 505 and located in the stabilizing tube 403. The outer surface of the output tube 506 is threadedly connected to a threaded sleeve 507 extending to the outside of the stabilizing tube 403 and fixed to the docking joint 7. The planetary gear system with the threaded connection can fully expand the torque and further improve the tightness of the fit between the ejector pin head and the aluminum wire disk. A circle of internal teeth is fixed on the inner side of the stabilizing tube 403, and the internal teeth are meshed with the six planetary gears 504.

[0037] In addition, the opening and closing component 6 includes a worm 601 rotatably connected to the inner bottom wall of the stabilizing hole through a bearing, the inner left wall of the stabilizing hole is rotatably connected to a transmission shaft 602 which passes through the right side wall of the stabilizing hole, the control component 4 and extends to the telescopic component 5 in sequence through a bearing, the outer surface of the transmission shaft 602 and is located in the stabilizing hole. A worm wheel 603 meshing with the worm 601 is fixed, the worm wheel 603 and the worm 601 have a reverse stroke self-locking function, which can ensure that when the arc plate 6061 rotates outward, it is difficult to be pressed back by external force, which can effectively improve the stability of the support, and the right side of the transmission shaft 602 and the inner side of the telescopic component 5 is fixed with a driving shaft 604 extending to the outside of the telescopic component 5 and passing through the docking joint 7, the outer surface of the driving shaft 604 and the right side of the docking joint 7 are provided with a filling portion 605, and the right side of the driving shaft 604 is provided with a support portion 606 hinged to the docking joint 7, the filling portion 605 and the support portion 606 cooperate to compensate for the worn parts and improve the overall stability of the ejector pin head.

[0038] It should be further explained that the replacement part 605 includes a rotating disk 6051 fixed to the outer surface of the driving shaft 604 and located on the right side of the docking head 7. The rotating disk 6051 is provided with six arc-shaped movable grooves that penetrate the rotating disk 6051. When the rotating disk 6051 rotates, it can cause the six driving rods 6052 to move outward, and cooperate with the T-block to ensure the stable movement of the movable rods 6053. Each movable groove is movably connected with a driving rod 6052 that penetrates the movable groove. A movable rod 6053 is fixed on the side of each driving rod 6052 close to the docking head 7. The driving shaft 604 includes a stabilizing shaft and a movable shaft. The stabilizing shaft is fixed to the transmission shaft 602. The axis extends into the stable axis, and a plurality of movable keys are fixed on the outer surface of the movable axis. The stable axis is provided with a plurality of movable key slots. The plurality of movable keys are movably connected with the plurality of movable key slots. The movable key slots cooperate with the movable keys to ensure that when the ejector head is adjusted in length, the power can still be smoothly transmitted to the filling portion 605, thereby stably supporting and stabilizing the aluminum wire plate. A T-block is fixed on one side of each movable rod 6053 close to the docking joint 7. Six T-slots are provided on the right side of the docking joint 7. The six T-blocks extend into the six T-slots respectively and are movably connected with the T-slots. The T-slots and the T-blocks can cooperate with each other to further improve the stability of the movable rod 6053.

[0039] It can be known that the support part 606 includes a circular plate 6062 which is rotatably connected to the right side of the driving shaft 604 through a bearing. The circular plate 6062 and the arc plate 6061 are hinged, and sufficient space is reserved between the two to ensure that the arc plate 6061 can rotate smoothly around the hinge point. Six arc plates 6061 are hinged on the outer side of the circular plate 6062, and each arc plate 6061 is abutted against the docking joint 7. The arc plates 6061 are abutted against the docking joint 7 to ensure stability when not expanded and reduce the overall gap. A hinge block is fixed on the inner side of each arc plate 6061, and a hinge rod is hinged on each hinge block. The six hinge rods are hinged to the six movable rods 6053 on the side away from the hinge block.

[0040] In this embodiment, when the ejector pin head is worn to a certain extent, the worm 601 is rotated. A hexagram groove is provided on the top of the worm 601. The worm 601 can be quickly rotated using a special tool. At the same time, the countersunk head design can reduce accidental touches.

[0041] It can be understood that the installation component 2 can improve the installation efficiency, the control component 4 and the telescopic component 5 cooperate to solve the problem of insufficient replacement space and improve the tightness of the contact between the ejector head and the aluminum wire disk. Finally, the opening and closing component 6 can compensate for wear, increase service life and reduce replacement frequency.

[0042] The working principle of the above embodiment is:

[0043] (1) During installation, it is only necessary to align the six threaded rods 2052 with the installation position on the aluminum wire winding device, then hold the ejector pin head and push it inward, and at the same time rotate the active rod 201. The power of the active rod 201 is transmitted to the stabilizing rod 204 through the active bevel gear 202 and the driven bevel gear 203. The power is further transmitted from the active gear 2051 to the six threaded rods 2052 through the driven gear 2053. The six threaded rods 2052 rotate at the same time to achieve threaded connection with the installation position of the aluminum wire winding device, thereby achieving rapid fixation.

[0044] (2) After the installation is completed, the knob 402 is turned, and the knob 402 drives the connecting tube 501 to rotate, further transmitting the power to the sun gear 502. Since the stabilizing tube 403 is limited by the limit frame 3, the internal teeth do not move. At this time, the planetary gear 504 will revolve around the sun gear 502 and rotate at the same time. The revolution power is output to the output tube 506 through the planetary rod 503 and the driving disk 505, prompting the output tube 506 to rotate. Since the docking joint 7 is limited by the limit frame 3, the threaded sleeve 507 will not rotate at this time. Due to the threaded connection relationship between the output tube 506 and the threaded sleeve 507, the threaded sleeve 507 will rotate and move to the right, prompting the docking joint 7, the filling part 605 and the supporting part 606 to move to the right, thereby prompting the ejector pin head to fit tightly with the aluminum wire disk.

[0045] (3) When wear occurs and stability is reduced, it is only necessary to rotate the worm 601, and the worm 601 drives the worm wheel 603 to rotate, which further drives the transmission shaft 602 and the driving shaft 604 to rotate. When the T-block and the rotating disk 6051 rotate, the six moving rods 6053 are prompted to move outward. Under the joint action of the circular plate 6062 and the arc plate 6061 and the moving rods 6053, the six arc plates 6061 will expand outward, thereby increasing the inclination of the six arc plates 6061, replenishing the worn parts, and ensuring overall stability.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0047] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
