[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides an embodiment of a metal triangular piece with an adjustable needle rail polished surface, including a base 1 and a lower needle rail 2. The lower needle rail 2 is located at the bottom of the front end of the base 1, and an upper needle rail 11 is located at the top of the front end of the base 1. A first positioning block 12 and a second positioning block 14 are fixedly connected to the rear end of the upper needle rail 11. A first reserved groove 10 and a second reserved groove 13 are respectively located at the front end of the base 1. A fixing rod 9 is fixedly connected between the interiors of the first reserved groove 10. An adjusting shaft 15 is longitudinally inserted through the interior of the second reserved groove 13. A handle 16 is fixedly connected to the top end of the adjusting shaft 15.
[0025] The adjusting shaft 15 has an external thread on its exterior, and the second positioning block 14 has an internal thread on its inner wall.
[0026] The fixed rod 9 and the adjusting shaft 15 are on the same horizontal plane, and the first positioning block 12 and the second positioning block 14 are on the same horizontal plane;
[0027] The second positioning block 14 is sleeved on the outside of the adjusting shaft 15, and the first positioning block 12 is sleeved on the inside of the fixing rod 9 and is movable.
[0028] Specifically, such as Figure 1 and Figure 2As shown, when it is necessary to adjust the distance between the upper needle rail 11 and the lower needle rail 2, the adjusting shaft 15 can be turned. At this time, the second positioning block 14 can move on the adjusting shaft 15, and the first positioning block 12 can move on the fixed rod 9, so as to facilitate and stabilize the adjustment of the distance.
[0029] The base 1 has mounting grooves 3 on both sides of the front end, and mounting blocks 4 are fixedly connected to the four corners of the rear end of the lower needle rail 2.
[0030] The mounting block 4 is removable and is embedded inside the mounting groove 3. There are four sets of mounting blocks 4.
[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the lower needle rail 2 needs to be replaced, the lower needle rail 2 can be removed. At this time, the mounting block 4 can be quickly detached from the mounting slot 3 for easy and quick installation and removal.
[0032] The base 1 and the lower needle rail 2 are provided with mounting holes 5 at their front ends, the lower needle rail 2 is provided with a circular groove 8 inside its front end, and the lower needle rail 2 is provided with a rubber gasket 6 at its front end.
[0033] The rear end of the rubber washer 6 is fixedly connected to a connecting block 7, which is detachable and embedded inside the circular groove 8.
[0034] Specifically, such as Figure 1 and Figure 4 As shown, the connecting block 7 behind the rubber washer 6 is inserted into the circular groove 8 and fixed, so that the rubber washer 6 is fixed at the front end of the lower needle rail 2. This makes it easier to prevent the front end of the circular groove 8 of the lower needle rail 2 from wearing out during assembly, and provides a certain degree of protection.
[0035] Working principle: When using this utility model, firstly, the connecting block 7 behind the rubber washer 6 is inserted into the circular groove 8 and fixed, so that the rubber washer 6 is fixed at the front end of the lower needle rail 2. This makes it easier to avoid wear at the front end of the circular groove 8 of the lower needle rail 2 during assembly, and has a certain protective effect. Then, when it is necessary to adjust the distance between the upper needle rail 11 and the lower needle rail 2, the adjusting shaft 15 can be turned. At this time, the second positioning block 14 can move on the adjusting shaft 15, and the first positioning block 12 can move on the fixing rod 9, so as to facilitate and stabilize the adjustment of the distance. Finally, when it is necessary to replace the lower needle rail 2, the lower needle rail 2 can be taken out. At this time, the mounting block 4 can be quickly detached from the mounting groove 3, which is convenient for quick installation and removal.
