[0031] Specifically, the upper surface of the connecting sleeve 204 is fixedly connected to the fixed frame 201, and the outer surface of the fixed frame 201 is threadedly connected to the positioning bolt 202, and the lower end of the positioning bolt 202 is in contact with the outer surface of the injection syringe 1, wherein the upper surface of the scraper 207 is fixedly connected to the protrusion 208, and the diameter of the protrusion 208 is smaller than the diameter of the discharge port 205, wherein the lower surface of the mixing shell 209 is fixedly connected to the electric telescopic rod 203, and the output end of the electric telescopic rod 203 passes through the inner wall of the mixing shell 209 and is fixedly connected to the lower surface of the scraper 207.

[0032] The positioning bolt 202 is further rotated so that the lower end of the positioning bolt 202 limits the outer surface of the injection syringe 1, and then the electric telescopic rod 203 is started. The output end of the electric telescopic rod 203 drives the scraper 207 to slide on the inner wall of the mixing shell 209, so as to facilitate the scraping of the double antibiotic bone cement adhered to the inner wall of the mixing shell 209 and transport the double antibiotic bone cement upward. The double antibiotic bone cement is squeezed by the scraper 207 and the protrusion 208, so that the double antibiotic bone cement flows from the discharge port 205 to the inner wall of the injection syringe 1, which is convenient for filling the double antibiotic bone cement and improves the utilization rate of the double antibiotic bone cement.

[0033] Example 2

[0034] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4, which is the second embodiment of the present utility model, is based on the previous embodiment. The cooling mechanism 3 includes a cooling shell 302 fixedly connected to the outer surface of the mixing shell 209, and multiple groups of cooling fans 303 are embedded in the outer surface of the cooling shell 302. A wind speed sensor 305 is fixedly connected to the inner wall of the cooling shell 302, and the outer surface of the voltage regulator 306 is electrically connected to the outer surface of the cooling fan 303 through a wire.

[0035] The specific cooling mechanism 3 also includes a connecting rod 304 fixedly connected to the inner wall of the cooling shell 302, the upper surface of the connecting rod 304 is fixedly connected to the voltage regulator 306, the outer surface of the cooling shell 302 is fixedly connected to the control panel 301, the outer surface of the control panel 301 is electrically connected to the temperature sensor 307 through a wire, the temperature sensor 307 is fixedly connected to the outer surface of the mixing shell 209, and the outer surface of the mixing shell 209 is fixedly connected to multiple groups of heat dissipation fins 308, and the outer surface of the cooling shell 302 is provided with heat dissipation holes. The temperature sensor 307 can accurately sense the temperature change of the mixing shell 209 in real time and The temperature data is converted into an electrical signal and transmitted to the control panel 301. After receiving the signal from the temperature sensor 307, the control panel 301 analyzes and processes it according to the preset program and algorithm, and quickly makes a control decision. When it is determined that the temperature exceeds the preset range and needs to be cooled, the control panel 301 sends an instruction to the voltage regulator 306. The voltage regulator 306 changes the speed of the cooling fan 303 by adjusting the output voltage. When cooling is required, the voltage is increased to accelerate the operation of the cooling fan 303, thereby increasing the air circulation speed, accelerating the heat dissipation, and achieving rapid cooling of the target area or equipment to ensure that the temperature is always maintained within the appropriate range.

[0036] Furthermore, the temperature sensor 307 transmits a signal to the control panel 301 indicating that the temperature of the mixing shell 209 is too high, so that the control panel 301 controls the voltage regulator 306 to increase the voltage of the cooling fan 303, thereby increasing the speed of the cooling fan 303, thereby increasing the air circulation, improving the cooling effect of the mixing shell 209, and preventing the antibiotics from becoming ineffective due to excessive temperature.

[0037] Working principle: First, rotate the connecting sleeve 204 to separate the connecting sleeve 204 and the threaded ring 206, then add the raw materials for preparing the double antibiotic bone cement into the mixing shell 209, and start the cooling fan 303 at the same time. The cooling fan 303 blows the external air flow into the cooling shell 302 and discharges it from the air outlet, so as to cool the outer surface of the mixing shell 209. At the same time, the temperature sensor 307 detects the outer surface of the mixing shell 209. When the temperature is too high, the temperature sensor 307 transmits a signal to the control panel 301, so that the control panel 301 controls the voltage regulator 306 to increase the voltage of the cooling fan 303, thereby increasing the speed of the cooling fan 303, which is convenient for increasing the circulation of air and improving the mixing The cooling effect of the shell 209 is achieved. When the stirring is completed, the injection syringe 1 is prevented from contacting the upper surface of the connecting sleeve 204, and then the positioning bolt 202 is rotated so that the lower end of the positioning bolt 202 limits the outer surface of the injection syringe 1. Then the electric telescopic rod 203 is started, and the output end of the electric telescopic rod 203 drives the scraper 207 to slide on the inner wall of the mixing shell 209, so as to facilitate the scraping of the double antibiotic bone cement adhered to the inner wall of the mixing shell 209 and transport the double antibiotic bone cement upward. The double antibiotic bone cement is squeezed by the scraper 207 and the protrusion 208, so that the double antibiotic bone cement flows from the discharge port 205 to the inner wall of the injection syringe 1, which is convenient for filling the double antibiotic bone cement and improves the utilization rate of the double antibiotic bone cement.
