[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figures 1 to 6 As shown, the utility model provides a needle adjustment card clamping slider, including a base 1, a slide groove 2 is opened inside the base 1, a slider 3 is slidably connected inside the slide groove 2, a mounting seat 4 is fixedly installed on the slider 3 away from the slide groove 2, a fixed shaft 5 is fixedly installed above the mounting seat 4, and a gear 6 is rotatably connected to the outside of the fixed shaft 5, a mounting groove 7 is opened inside the base 1, the mounting groove 7 is located behind the slide groove 2, a rack 8 is fixedly installed inside the mounting groove 7, the rack 8 is meshed with the gear 6, and a block 13 is clamped on the outside of the rack 8, a top plate 20 is fixedly installed above the mounting seat 4, and a placement plate 21 is fixedly installed on the side of the top plate 20 close to the center point of the base 1.
[0022] The mounting seat 4 can be moved by the sliding action of the slider 3 and the slide groove 2. At this time, the displacement accuracy of the mounting seat 4 is controlled due to the meshing action of the gear 6 and the rack 8. When the displacement reaches the same value as the width or diameter of the needle adjustment card, the card block 13 is engaged with the gear 6, so that the gear 6 is limited, thereby achieving the effect of fixing the mounting seat 4.
[0023] Among them, a fixing plate 9 is fixedly installed above the mounting seat 4, and a connecting rod 10 is movably connected inside the fixing plate 9. The connecting rod 10 is fixedly connected to the block 13. A spring 11 is sleeved on the outer side of the connecting rod 10. A limiting ring 12 is fixedly installed on the side of the spring 11 close to the block 13. The limiting ring 12 is fixedly connected to the fixing plate 9, and a fixing block 14 is fixedly installed on the end of the fixing plate 9 away from the block 13.
[0024] The spring 11 always provides elastic force in the direction of the block 13. When there is no external force, the block 13 will be stuck inside the gear 6, thereby preventing the block 13 from loosening and falling off.
[0025] Among them, the interior of the fixed block 14 is provided with a slide groove 2 15, the interior of the slide groove 2 15 is slidably connected to the slide rod 16, the outer side of the slide rod 16 is rotatably connected to the connecting block 17, and the end of the connecting block 17 away from the slide rod 16 is fixedly installed with a connecting shaft 18, and the outer side of the connecting shaft 18 is sleeved with a fixed block 2 19, and the fixed block 2 19 is fixedly connected to the mounting seat 4.
[0026] The second slide groove 15 is inclined. When the connecting shaft 18 is pushed toward the slide rod 16, the slide rod 16 will pull the second slide groove 15 away from the fixed plate 1 9, causing the block 13 to shrink, thereby releasing the block 13 from the engagement with the gear 6, thereby allowing the mounting base 4 to move.
[0027] Among them, a second fixing plate 22 is fixedly installed above the placement plate 21, a telescopic rod 23 is fixedly installed at the bottom of the second fixing plate 22, a second spring 24 is sleeved on the outside of the telescopic rod 23, and a bottom plate 25 is fixedly installed at the bottom of the second spring 24.
[0028] When the needle adjustment card needs to be clamped, the bottom plate 25 is first lifted upward to contract the second spring 24. After the needle adjustment card is placed under the bottom plate 25, the bottom plate 25 is released to allow the second spring 24 to provide elastic force downward, so that the vertical direction of the needle adjustment card can also be clamped.
[0029] There are two mounting seats 4, both of which are located inside the base 1, and there are two sliders 3, both of which are slidably connected to the slide groove 1 2.
[0030] The main function of the two sliders 3 is to limit the mounting seat 4 when the mounting seat 4 is displaced by sliding with the slide groove 1 2, thereby ensuring the stability of the lateral displacement of the mounting seat 4 and preventing angular deviation.
[0031] There are two placement plates 21 , both of which are located above the two mounting seats 4 , and the two placement plates 21 are located on one side of the fixing block 2 19 close to the center point of the base 1 .
[0032] The main function of the two placement plates 21 is to facilitate the support of the needle adjustment card when clamping the needle adjustment card, and at the same time achieve the effect of clamping needle adjustment cards of different widths and shapes.
[0033] The working principle and use process of this utility model:
[0034] First, press the connecting shaft 18 toward the sliding rod 16, so that the sliding rod 16 squeezes the second slide 15 and slides the second slide 15, thereby moving the second slide 15 away from the fixed plate 1 9, and the connecting rod 10 drives the clamping block 13 to move toward the second slide 15, so that the gear 6 is not stuck and can rotate;
[0035] Next, the mounting seat 4 is pushed to move by the sliding action of the slider 3 and the slide groove 1 2, and the distance between the mounting seat 4 and the center point is adjusted so that the distance between the mounting seat 4 and the center point is just enough to engage the needle card. Then, the connecting shaft 18 is loosened, so that the spring 11 provides elastic force to engage the clamping block 13 into the interior of the gear 6, thereby achieving the effect of fixing the mounting seat 4;
[0036] Finally, since the placement plate 21 is fixedly installed above the placement plate 21, the telescopic rod 23 is fixedly installed at the bottom of the placement plate 21, the spring 24 is sleeved on the outside of the telescopic rod 23, and the bottom of the spring 24 is fixedly installed with the bottom of the bottom plate 25, when the needle adjusting card needs to be clamped, the bottom plate 25 is first lifted upward to make the spring 24 contract. After the needle adjusting card is placed under the bottom plate 25, the bottom plate 25 is loosened to make the spring 24 provide elastic force downward, so that the vertical direction of the needle adjusting card can also be clamped.
