A single needle ejector can be equipped with needle ejectors and connectors of different specifications to meet the needs of multi-functional needle ejection and reduce the cost of using the needle ejector."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model uses a locking bolt to secure different needle ejector components during use. However, in actual use, when facing situations requiring urgent repairs or rapid handling, it is necessary to change to different needle ejector components. The current method of securing with screws requires repeated disassembly and reinstallation of the required needle ejector, followed by retightening the screws. This increases the workload of the staff and slows down the repair work. Therefore, it is necessary to improve the design by incorporating an easy-to-use anti-bending needle ejector to solve the above problems. Utility Model Content

[0006] To overcome the problem that when using different ejector pins, it is necessary to disassemble them and then tighten the fastening screws again before fixing them, which is time-consuming, laborious and slows down the maintenance work.

[0007] The technical solution of this utility model is as follows: an easy-to-install anti-bending needle retraction device, including a main rod, a slide rail and a protective mechanism. The protective mechanism is provided on the outside of the main rod. The slide rail is fixedly connected inside the main rod. A sliding block is slidably connected to the outside of the slide rail. A locking block is fixedly connected to the inside of the sliding block. A plug-in seat is locked to the outside of the locking block. The needle retraction body is fixedly connected to the top of the plug-in seat. A first spring is fixedly connected between the sliding block and the main rod. In use, the sliding block drives the locking block to lock the plug-in seat.

[0008] Preferably, the sliding block has a matching groove at the position of the slide rail, and the sliding block is slidably connected to the outside of the slide rail through the groove.

[0009] Preferably, a push button is slidably connected inside the main rod, a first sliding plate is fixedly connected to the top of the push button, a first fixing rod is fixedly connected to the top of the first sliding plate, the first fixing rod is slidably connected inside the main rod, a second fixing rod is fixedly connected inside the first fixing rod, the second fixing rod is slidably connected inside the sliding block, a second sliding plate is slidably connected inside the main rod, a second spring is fixedly connected between the second sliding plate and the main rod, a rotating ring is rotatably connected inside the main rod, a sliding ring is threaded inside the rotating ring, and the sliding ring is slidably connected to the outside of the main rod.

[0010] Preferably, the sliding block has a groove at the relative position of the second fixed rod, and the second fixed rod is slidably connected inside the groove.

[0011] Preferably, the main rod has a groove at the relative position of the second sliding plate, and the second sliding plate is slidably connected inside the groove.

[0012] Preferably, the protective mechanism includes a protective shell, which is disposed outside the main rod. A first fixing buckle is fixedly connected to the outside of the protective shell, and a knob is rotatably connected inside the first fixing buckle. A second fixing buckle is fixedly connected to the outside of the main rod, and a third spring is fixedly connected between the knob and the first fixing buckle.

[0013] Preferably, there are two first fixing buckles, two knobs, and two second fixing buckles. The two first fixing buckles are symmetrically fixedly connected to the outside of the protective shell, the two knobs are rotatably connected to the inside of the two first fixing buckles, and the two second fixing buckles are symmetrically fixedly connected to the outside of the main rod.

[0014] The beneficial effects of this utility model are as follows: Compared with fixing by fastening bolts, by adding a slide rail, sliding block, snap-fit ​​block and first spring, during installation, the plug-in seat is pushed inward by the chamfer, and then the first spring pushes the sliding block to make the snap-fit ​​block automatically snap into the plug-in seat slot to achieve fixation. This avoids the problem of having to retighten the fastening screws again after disassembling when using different ejector pins, which is time-consuming, laborious and slows down maintenance work.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment of an easy-to-install anti-bending needle retraction device, including a main rod 1, a slide rail 21, and a protective mechanism. The protective mechanism is provided on the outside of the main rod 1. The slide rail 21 is fixedly connected inside the main rod 1. A sliding block 22 is slidably connected to the outside of the slide rail 21. A locking block 23 is fixedly connected to the inside of the sliding block 22. A plug-in seat 24 is locked to the outside of the locking block 23. A needle retraction body 25 is fixedly connected to the top of the plug-in seat 24. A first spring 26 is fixedly connected between the sliding block 22 and the main rod 1. In use, the sliding block 22 slides, causing the locking block 23 to lock onto the plug-in seat 24. The plug-in seat 24 and the needle retraction body 25 are inserted into the main rod 1. The chamfer at the bottom of the plug-in seat 24 pushes the locking block 23 and the sliding block 26 together. 2. Slide inwards, and after the connector 24 is downward, adjust its angle so that the locking block 23 is inserted into the slot opened in the connector 24, thereby fixing the position of the connector 24 and the needle retraction body 25 to complete the installation. During subsequent disassembly, the sliding block 22 slides to drive the locking block 23 to release the restriction on the connector 24, thereby pulling out the connector 24 for replacement. When not performing maintenance work, the protective mechanism protects the needle retraction body 25 from external interference that may cause the needle retraction body 25 to bend. The sliding block 22 has a matching groove at the position of the slide rail 21. The sliding block 22 is slidably connected to the outside of the slide rail 21 through the groove. The groove limits the sliding of the sliding block 22 and prevents the sliding block 22 from disengaging from the slide rail 21, thereby locking the locking block 23 with the connector 24.

[0024] Please see Figure 1 - Figure 5In this embodiment, a push button 27 is slidably connected inside the main rod 1. A first sliding plate 28 is fixedly connected to the top of the push button 27. A first fixing rod 29 is fixedly connected to the top of the first sliding plate 28. The first fixing rod 29 is slidably connected inside the main rod 1. A second fixing rod 210 is fixedly connected inside the first fixing rod 29. The second fixing rod 210 is slidably connected inside the sliding block 22. A second sliding plate 211 is slidably connected inside the main rod 1. A second spring 212 is fixedly connected between the second sliding plate 211 and the main rod 1. A rotating ring 213 is rotatably connected inside the main rod 1. A sliding ring 214 is threadedly connected inside the rotating ring 213. The sliding ring 214 is slidably connected to the outside of the main rod 1 and moves towards the second sliding plate 212 via the second spring 212. 11 provides thrust. When it is necessary to replace the needle retraction body 25, pressing the press button 27 causes the locking block 23 to disengage from the plug-in seat 24, allowing the plug-in seat 24 to automatically pop out a certain distance, making it easier for the user to remove. The sliding block 22 has a groove at the relative position of the second fixed rod 210. The second fixed rod 210 is slidably connected inside the groove. The groove prevents the second fixed rod 210 from disengaging from the sliding block 22, while the second fixed rod 210 and the groove cooperate to allow the sliding block 22 to slide. The main rod 1 has a groove at the relative position of the second sliding plate 211. The second sliding plate 211 is slidably connected inside the groove. The groove restricts the sliding of the second sliding plate 211, preventing the second sliding plate 211 from shifting and affecting the pop-out of its plug-in seat 24.

[0025] Please see Figure 1 , Figure 6 In this embodiment, the protective mechanism includes a protective shell 31, which is disposed outside the main rod 1. A first fixing buckle 32 is fixedly connected to the outer side of the protective shell 31, and a knob 33 is rotatably connected inside the first fixing buckle 32. A second fixing buckle 34 is fixedly connected to the outer side of the main rod 1. A third spring 35 is fixedly connected between the knob 33 and the first fixing buckle 32. The third spring 35 provides a pushing force to the knob 33, causing it to cooperate with the second fixing buckle 34, thereby better fixing the protective shell 31 to the outside of the main rod 1. Two first fixing buckles 32, two knobs 33, and two second fixing buckles 34 are provided. The two first fixing buckles 32 are symmetrically fixedly connected to the outside of the protective shell 31. The two knobs 33 are respectively rotatably connected to the inside of the two first fixing buckles 32. The two second fixing buckles 34 are symmetrically fixedly connected to the outside of the main rod 1. By setting two first fixing buckles 32, knobs 33 and second fixing buckles 34, the protective shell 31 is fixed from both sides, making it more firmly fixed to the outside of the protective shell 31, protecting the needle retraction body 25 from bending caused by external factors.

[0026] During operation, the connector 24 is inserted into the main rod 1. During insertion, the chamfer at the bottom of the connector 24 pushes the locking block 23 outwards, causing the connector 24 to slide downwards and press against the second sliding plate 211 and the second spring 212. When the second sliding plate 211 slides to the bottom of the groove on the main rod 1 at its relative position, the connector 24 and the needle retraction body 25 are rotated and adjusted. The first spring 26 provides a pushing force to the sliding block 22, pushing the sliding block 22 so that the locking block 23 inserts into the groove on the connector 24 at its relative position, thus securing the connector 24 and the needle retraction body 25. Then, the rotating ring 213 is rotated to slide out the sliding ring 214, thereby retracting the press button 27 inside to prevent accidental contact that could cause the connector 24 to detach. For subsequent disassembly, the rotating ring 213 is rotated to slide the sliding ring 214 into the main rod 1. Pressing the button 27 pushes the first sliding plate 28 and the first fixing rod 29 to slide upwards. Then, through the cooperation of the second fixing rod 210 inside the first fixing rod 29 and the sliding block 22 with the groove opened at their relative positions, the sliding block 22 and the locking block 23 are driven to slide outwards, releasing the restriction on the plug-in seat 24. Then, the second spring 212 provides a pushing force to the second sliding plate 211, causing the second sliding plate 211 to slide upwards a certain distance and push out the plug-in seat 24, so that the staff can easily take out the plug-in seat 24 and the needle removal body 25 for replacement. Afterwards, when not in use, press the knob 33 and put the protective shell 31 on the outside of the main rod 1. When the knob 33 is released, the third spring 35 provides a pushing force to the knob 33, causing it to rotate back to its original position and contact the second fixing buckle 34, thereby restricting the position of the protective shell 31 and protecting the needle removal body 25 from bending caused by external factors.

[0027] By adding slide rail 21, sliding block 22, snap-fit ​​block 23 and first spring 26 through the above steps, the problem of having to retighten the fastening screws again after disassembling different ejector pins can be solved, which is time-consuming, laborious and slows down the maintenance work.
