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.

The lower end of the second sliding block 8 is slidably connected to the inner wall of the locator base 1, and the inner wall of the locator base 1 is provided with a limit assembly; the limit assembly includes a rectangular block 13, the outer wall of the rectangular block 13 is fixedly connected to the inner wall of the locator base 1, the upper surface of the rectangular block 13 is fixedly connected to the limit block 11, the outer wall of the limit block 11 is fixedly connected to the inner wall of the locator base 1, the upper surface of the rectangular block 13 is fixedly connected to the limit strip 12, and the outer wall of the limit strip 12 is fixedly connected to the inner wall of the locator base 1, the outer wall of the first connecting column 6 is slidably connected to the outer wall of the limit block 11, the outer wall of the first connecting column 6 is slidably connected to the outer wall of the limit strip 12, the outer wall of the second connecting column 9 is slidably connected to the outer wall of the limit block 11, the outer wall of the second connecting column 9 is slidably connected to the outer wall of the limit strip 12, the lower end of the first lower arc positioning plate 7 is slidably connected to the upper surface of the limit block 11, and the lower end of the second lower arc positioning plate 10 is slidably connected to the upper surface of the limit block 11;

[0028] Specifically, the rotating knob 4 is used to drive the bidirectional screw 3 to rotate inside the locator base 1 and the fixed block 2. By rotating the bidirectional screw 3 forward and backward, the first sliding block 5 and the second sliding block 8 can be caused to move inward or outward at the same time, and then the first lower arc positioning plate 7 and the second lower arc positioning plate 10 are driven to move inward or outward at the same time through the first connecting column 6 and the second connecting column 9, thereby achieving the fixing and releasing of the mixing tube. The limit block 11 and the limit bar 12 are used to limit the movement stroke of the first connecting column 6 and the second connecting column 9 , which can ensure that the first connecting column 6 and the second connecting column 9 always move along a straight line during the movement process, thereby ensuring the accuracy of the fit of the first lower arc positioning plate 7 and the second lower arc positioning plate 10, and the mixing tube can be accurately fixed. The limit block 11 is used to support the first lower arc positioning plate 7 and the second lower arc positioning plate 10. During the movement of the first lower arc positioning plate 7 and the second lower arc positioning plate 10, the lower ends of the first lower arc positioning plate 7 and the second lower arc positioning plate 10 will always slide on the upper surface of the limit block 11.

[0029] Reference Figure 4 - Figure 6 , the inner wall of the first lower arc positioning plate 7 is slidably connected with an adjusting block 14, and the outer wall of the first lower arc positioning plate 7 is provided with a card slot 15; the interior of the adjusting block 14 is fixedly connected to an L-shaped plate 16, the outer wall of the L-shaped plate 16 is fixedly connected to a connecting block 17, and the interior of the connecting block 17 is fixedly connected to a fixing column 18; the outer wall of the fixing column 18 is rotatably connected to a card plate 19, and the outer wall of the card plate 19 is fixedly connected to a spring 20, one end of the spring 20 is fixedly connected to the outer wall of the L-shaped plate 16; the upper surface of the adjusting block 14 is fixedly connected to a first upper arc positioning plate 26, the lower end of the first upper arc positioning plate 26 is fixedly connected to a first adjusting column 21, the lower end of the first adjusting column 21 is fixedly connected to a limiting piece 22, and a limiting groove 23 is provided inside the first lower arc positioning plate 7; the outer wall of the limiting piece 22 is slidably connected to the inner wall of the limiting groove 23;

[0030] Specifically, the L-shaped plate 16 is used to fix the connecting block 17 and the spring 20. The spring 20 is used to move and reset the card plate 19. When the card plate 19 is subjected to pressure, the spring 20 is pressed to contract. When the card plate 19 is no longer subjected to external pressure, the spring 20 rebounds and resets, thereby pushing the card plate 19 to move and reset. The limiting piece 22 can limit the first adjusting column 21 and then limit the first upper arc positioning plate 26, thereby preventing the first upper arc positioning plate 26 from moving forward. When the length of the line is adjusted, it is pulled out and affects its use. The card plate 19 can limit the adjusting block 14 and then limit and fix the first upper arc-shaped positioning plate 26. When the outer wall of the card plate 19 is slidably connected to the inner wall of the card slot 15 opened on the outer wall of the first lower arc-shaped positioning plate 7, the adjusting block 14 will always maintain the adjusted length unless it is subjected to pressure. The outer wall of the first lower arc-shaped positioning plate 7 is provided with multiple card slots 15, which can be used to adapt to mixing tubes of various lengths.

[0031] Reference Figure 1 The upper end of the second lower arc-shaped positioning plate 10 is fixedly connected to the second adjusting column 24, and the upper end of the second adjusting column 24 is fixedly connected to the second arc-shaped positioning plate 25. The outer wall of the second arc-shaped positioning plate 25 is in contact with the outer wall of the first upper arc-shaped positioning plate 26;

[0032] Specifically, when the second arc-shaped positioning plate 25 moves upward to a position in contact with the first upper arc-shaped positioning plate 26 in the same manner, the positioning length adjustment of the positioner is completed.

[0033] Working principle: When the device needs to be used, it is only necessary to turn the rotating knob 4 to drive the bidirectional screw rod 3 to rotate inside the locator base 1. When the bidirectional screw rod 3 rotates inside the locator base 1, it will rotate inside the fixed block 2. When the bidirectional screw rod 3 rotates, it will simultaneously rotate inside the first sliding block 5 and the second sliding block 8 and drive the first sliding block 5 and the second sliding block 8 to move inward at the same time and slide on the outer wall of the locator base 1, thereby driving the first connecting column 6 and the second connecting column 9 to move inward at the same time. During the inward movement of the first connecting column 6 and the second connecting column 9, they will simultaneously slide on the outer walls of the limit block 11 and the limit bar 12, and the first lower arc positioning plate 7 and the second lower arc will be driven inward by the first connecting column 6 and the second connecting column 9. The shaped positioning plate 10 moves inward at the same time and slides on the upper surface of the limit block 11 at the same time, so that the required mixing tube can be fixed. When it is necessary to release the fixed state of the mixing tube, it is only necessary to rotate the rotating knob 4 in the opposite direction to drive the bidirectional screw rod 3 to rotate again inside the locator base 1 and the fixed block 2, thereby prompting the first sliding block 5 and the first connecting column 6 to move outward at the same time, and then through the first connecting column 6 and the second connecting column 9, the first lower arc positioning plate 7 and the second lower arc positioning plate 10 are released from the fitting state, so as to release the fixed state of the mixing tube, thereby achieving the effect of quickly and conveniently positioning and fixing the powder medicine mixing tube, thereby saving the operator's time and energy and improving the detection efficiency. When it is necessary to position mixing tubes of different lengths, When the first upper arc positioning plate 26 is pulled, the adjusting block 14 is driven to slide on the inner wall of the first lower arc positioning plate 7. During the sliding process of the adjusting block 14, the card plate 19 is continuously subjected to pressure and rotates on the outer wall of the fixing column 18. At the same time, the card plate 19 subjected to pressure will continuously press the spring 20 to contract. When the card plate 19 slides to the inner wall of the card groove 15 opened on the outer wall of the first lower arc positioning plate 7, the card plate 19 is no longer subjected to force. At this time, the spring 20 rebounds and pushes the card plate 19 to slide on the outer wall of the fixing column 18 again and engages with the inner wall of the card groove 15 opened on the outer wall of the first lower arc positioning plate 7 to limit the connecting block 17. During the sliding process of the adjusting block 14, the first upper arc positioning plate 26 fixedly connected to the upper surface of the adjusting block 14 will drive the first adjusting column 2 1 moves upward, thereby causing the limiting piece 22 to slide on the inner wall of the limiting groove 23 and move upward. When the second arc-shaped positioning plate 25 moves upward in the same manner to a position in contact with the first upper arc-shaped positioning plate 26, the effect of positioning and fixing powder drug mixing tubes of different lengths is achieved, thereby being applicable to mixing tubes of different lengths, improving the scope of application and flexibility. During use, the device can not only achieve the effect of quickly and conveniently positioning and fixing the powder drug mixing tubes, thereby saving the operator's time and energy and improving the detection efficiency, but also achieve the effect of positioning and fixing powder drug mixing tubes of different lengths, thereby being applicable to mixing tubes of different lengths, improving the scope of application and flexibility.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
