[0002] A stainless steel needle is a hollow, tubular instrument made of stainless steel, usually with a very sharp end. The manufacturing process involves winding and cutting many long steel tubes, then arranging them on a tray for grinding. After arranging them on the tray, they are glued together to form a needle tube array, then cut to form the needle tip, and finally ball-milled and polished to obtain the stainless steel needle.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-5 This utility model provides a quick-release stainless steel needle tube, including an installation mechanism 1 and an adjustment mechanism 2 located below the installation mechanism 1, with a stainless steel needle body 3 disposed below the adjustment mechanism 2.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, the mounting mechanism 1 includes a mounting base 101. The mounting base 101 has a mounting groove inside. Mounting plates 104 are movably pinned to the left and right sides of the lower inner wall of the mounting groove. The mounting plates 104 are arc-shaped. Eccentric wheels 105 are provided in opposite directions on the two mounting plates 104. A fixed shaft 106 is fixedly connected inside the eccentric wheel 105. A torsion spring 107 is sleeved on the outside of the fixed shaft 106. The eccentric wheel 105 is elastically connected to the mounting base 101 through the torsion spring 107. A rotating handle 108 is fixedly connected to the front of the fixed shaft 106. A positioning magnetic plate 102 is fixedly connected to the top of the inner wall of the mounting groove. A spherical mounting head 103 is provided in the mounting groove. The outer wall of the spherical mounting head 103 is made of magnetic material. The spherical mounting head 103 is hollow. A sealing ring is sleeved on the top of the spherical mounting head 103.

[0030] Through the above scheme: rotating the handle 108 causes the eccentric wheel 105 to rotate clockwise, inserting the spherical mounting head 103 into the mounting groove. The positioning magnetic plate 102 is used to attract and fix the spherical mounting head 103. When the handle 108 is released, since the eccentric wheel 105 is elastically connected to the mounting base 101 through the torsion spring 107, under the elastic force of the torsion spring 107, the eccentric wheel 105 drives the mounting plate 104 to rotate counterclockwise, thereby installing and fixing the spherical mounting head 103, and completing the installation and fixing of the stainless steel needle body 3.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the adjusting mechanism 2 includes a fixed column 201, which is fixedly connected to a spherical mounting head 103. A limit slider 202 is fixedly connected to the inner wall of the fixed column 201. An external threaded portion 203 is provided on the outer wall of the fixed column 201. A threaded sleeve 204 is connected to the external thread of the fixed column 201. Push rods 206 are slidably connected to the lower sides of the left and right sides of the fixed column 201. Push blocks 205 are fixedly connected to the two push rods 206 in opposite directions. Fixed blocks 207 are fixedly connected to the two push rods 206 in opposite directions. Each push rod 206 is sleeved with a... There is a fixed spring 208, and the fixed block 207 is elastically connected to the fixed column 201 through the fixed spring 208. A stainless steel needle body 3 is provided below the adjustment mechanism 2. The stainless steel needle body 3 includes a needle body 301, which is hollow. Limiting grooves 302 are provided on both the left and right sides of the needle body 301. The limiting grooves 302 are adapted to the limiting slider 202. Several fixing holes 303 are provided inside each limiting groove 302. The fixing holes 303 are adapted to the fixing block 207. Through holes 304 are provided on both the front and rear sides of the needle body 301.

[0032] The above method involves pulling the needle body 301 downwards, rotating the threaded sleeve 204 to move it downwards along the fixed post 201, squeezing the push block 205, and driving the push rod 206 to push the fixed block 207 into the fixed hole 303, thus completing the installation and fixing of the needle body 301. When it is necessary to loosen it, the threaded sleeve 204 is rotated in the opposite direction to move upwards. Since the fixed block 207 is elastically connected to the fixed post 201 through the fixed spring 208, under the elastic force of the fixed spring 208, the fixed block 207 is pushed away from the fixed hole 303, which allows the needle body 301 to be readjusted and moved, thus completing the length adjustment of the needle body 301.

[0033] Working principle:

[0034] In actual use, firstly, by rotating the handle 108, the eccentric wheel 105 is rotated clockwise, and the spherical mounting head 103 is inserted into the mounting groove. The positioning magnetic plate 102 is used to attract and fix the spherical mounting head 103. The torsion spring 107 is used to make the eccentric wheel 105 drive the mounting plate 104 to rotate counterclockwise, and the spherical mounting head 103 is installed and fixed, thus completing the installation and fixing of the stainless steel needle body 3.

[0035] Next, pull the needle body 301 down, and rotate the threaded sleeve 204 to move it down along the fixed post 201, squeezing the push block 205, which drives the push rod 206 to push the fixed block 207 into the fixed hole 303, thus completing the installation and fixing of the needle body 301. Rotate the threaded sleeve 204 in the opposite direction to move it up, and use the fixed spring 208 to push the fixed block 207 out of the fixed hole 303, so that the needle body 301 can be readjusted and moved to complete the length adjustment of the needle body 301.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
