DETAILED DESCRIPTION

[0020] The utility model provides a tetrafluoroethylene stirring blade amplification device, such as Figure 1-4 As shown, it includes a rod body 11, a joint 12, two groups of blades 13, two groups of magnifying sleeves 15, a positioning assembly and a connecting assembly. The rod body 11, the joint 12 and the inner sides of the blades 13 are connected by stainless steel, and the outer sides of the rod body 11, the joint 12 and the blades 13 are sleeved with polytetrafluoroethylene. The joint 12 is arranged at one end of the rod body 11, and the two groups of blades 13 are fixedly arranged on the outer circumferential surface of the joint 12. The two groups of blades 13 are symmetrically arranged. The two groups of magnifying sleeves 15 are provided with embedded grooves 25, and the magnifying sleeves 15 are sleeved on the outer sides of the blades 13 through the embedded grooves 25. Figure 3 As shown, the positioning component is arranged between the amplifying sleeve 15 and the paddle 13, the positioning component includes a first spring 23 and a first slider 24, and the positioning component is used to enable the amplifying sleeve 15 to feedback the positional relationship between the paddle 13 to the user, and the connecting component is arranged between the two groups of amplifying sleeves 15, the connecting component includes a second slider 20 and a second spring 21, and the connecting component is used to feedback the positional relationship between the two groups of amplifying sleeves 15 to the user.

[0021] like Figure 4 As shown, the embedding groove 25 passes through the front and rear ends of the blade 13.

[0022] A first slide groove 22 connected to the embedding groove 25 is provided in the magnifying sleeve 15, a first positioning groove 14 is provided in the paddle 13, the first positioning groove 14 corresponds to the position of the first slide groove 22, a first slider 24 is slidably disposed in the first slide groove 22, and a first spring 23 is fixedly connected between the first slider 24 and the inner wall of the first spring 23.

[0023] A second positioning groove 16 is defined in one of the enlargement sleeves 15 , and a second slide groove 17 is defined in the other enlargement sleeve 15 . The second positioning groove 16 corresponds to the second slide groove 17 . The second slider 20 is slidably disposed in the second slide groove 17 . The second spring 21 is fixedly disposed between the second slider 20 and the inner wall of the second slide groove 17 .

[0024] The inner walls of the first positioning groove 14 and the second positioning groove 16 are both arc-shaped, and one end of the second sliding block 20 and the first sliding block 24 are both hemispherical.

[0025] First, one of the magnifying sleeves 15 is put on the outer side of the paddle blade 13 along the thickness direction of the paddle blade 13, so that the paddle blade 13 slides relative to the embedding groove 25, and the magnifying sleeve 15 drives the first slider 24 to slide synchronously. When the first slider 24 abuts against the surface of the paddle blade 13, the first spring 23 is compressed. When the magnifying sleeve 15 drives the first slider 24 to slide to the first positioning groove 14, the first spring 23 restores its elastic deformation, thereby pushing the first slider 24 to slide into the first positioning groove 14, thereby positioning the position of the magnifying sleeve 15.

[0026] When installing another amplifying sleeve 15, the amplifying sleeve 15 is put on the outer side of the paddle blade 13 along the thickness direction of the paddle blade 13, and the operation on the amplifying sleeve 15 is repeated. At this time, the amplifying sleeve 15 drives the second slider 20 and the first slider 24 to move synchronously. When the second slider 20 and the first slider 24 move to the corresponding positions, the second spring 21 pushes the second slider 20 into the second positioning groove 16, and the first spring 23 pushes the first slider 24 into the first positioning groove 14, thereby completing the assembly and increasing the stirring area.
