During operation, when the metering rod 1 is connected to the connecting sleeve 11, the connecting key 13 is embedded in the key slot 12, and the connecting sleeve 11 is heated. After heating, the metering rod 1 is inserted into the end of the connecting sleeve 11 for connection. The connecting key 13 and the connecting sleeve 11 are made of the same material, and when the device is subjected to cold or hot deformation, the connecting key 13 and the connecting sleeve 11 have the same The expansion coefficient of the metering rod 1 and the connecting sleeve 11 is kept in a tight fit at all times. When the connecting key 13 is installed in the key slot 12, the clamping assembly and the fixing assembly fix the connecting key 13 inside the key slot 12. In this step, a ceramic-metal connection anti-slip structure is formed by setting the metering rod 1, the connecting sleeve 11, the key slot 12, the connecting key 13, the clamping assembly and the fixing assembly, so as to realize the function of the metering rod 1 and the connecting sleeve 11 always keeping a tight fit during hot and cold deformation of the device, solve the problem that the metering rod 1 and the connecting sleeve 11 fall off due to inconsistent hot and cold deformation, improve the stability of the device during connection, and reduce the problem that the connecting sleeve 11 has metal fatigue due to inconsistent hot and cold deformation of the metering rod 1 and the connecting sleeve 11.

[0025] like Figures 2 to 4 As shown, the clamping assembly includes a push rod 2, a first spring 21 and a cone 22. The push rod 2 is slidably connected to the outer wall of the connecting key 13. A pair of positioning grooves are opened on the inner wall of the metering rod 1 near the connecting key 13. One end of the first spring 21 is fixedly connected to the positioning groove on the inner wall of the metering rod 1. A pair of first springs 21 are arranged inside the metering rod 1, and are symmetrically arranged. The cone 22 is slidably connected to the middle part of the connecting key 13 near the push rod 2. The bottom end of the cone 22 is conical. During operation, after the connecting key 13 is installed in the key slot 12, the cone 22 is pressed downward, and the cone 22 squeezes the pair of push rods 2 to both sides, so that the push rods 2 is inserted into the positioning groove of the inner wall of the metering rod 1, and the first spring 21 is compressed. When replacing the connecting key 13, the cone 22 is pulled upward, and the first spring 21 pushes the push rod 2 out of the side wall of the metering rod 1, and then the connecting key 13 is removed from the key slot 12. In this step, the push rod 2, the first spring 21 and the cone 22 are arranged to form a clamping structure, which realizes the function of fixing the connecting key 13 to the metering rod 1, solves the problem of the connecting key 13 falling off from the outer wall of the metering rod 1, improves the stability of the connecting key 13 placed in the key slot 12, and reduces the situation where the metering rod 1 and the connecting sleeve 11 become loose due to the falling of the connecting key 13.

[0026] like Figure 2As shown, the adsorption assembly includes a guide rod 3, a first suction cup 31 and a second spring 32. The guide rod 3 is slidably connected to the bottom of the inner wall of the key slot 12. A pair of guide rods 3 are arranged at the bottom of the inner wall of the key slot 12, and are symmetrically arranged. The first suction cup 31 is fixedly connected to the end of the guide rod 3 close to the connecting key 13. One end of the second spring 32 is fixedly connected to the end of the guide rod 3 away from the first suction cup 31. The other end of the second spring 32 is fixedly connected to the inside of the metering rod 1. During operation, when the connecting key 13 is placed in the key slot 12, the bottom of the connecting key 13 contacts the first suction cup 31. And it is sucked by the first suction cup 31, the first suction cup 31 drives the guide rod 3 to slide downward and compresses the second spring 32. When the connecting key 13 is removed, the second spring 32 drives the guide rod 3 and the second spring 32 to reset. This step forms a fixed structure through the setting of the guide rod 3, the first suction cup 31 and the second spring 32, and realizes the function of fixing the connecting key 13 inside the key slot 12, solves the problem of the connecting key 13 being offset in the key slot 12, improves the stability of the connecting key 13 when placed inside the key slot 12, and reduces the possibility of the connecting key 13 falling off.

[0027] like Figure 4 As shown, a rotating rod 4 is hinged on the top of the cone 22. A pair of rotating rods 4 are arranged at the top of the cone 22 and are symmetrically arranged. The end of the rotating rod 4 away from the middle of the cone 22 is fixedly connected with a handle 41. During operation, when the cone 22 is pulled out, the handle 41 is moved to make the rotating rod 4 vertical at the top of the cone 22. The handle 41 is clamped with a vise and pulled upward to lift the cone 22 upward. This step forms a lifting structure through the setting of the rotating rod 4 and the handle 41, thereby realizing the function of lifting the cone 22 and improving the convenience of moving the cone 22 upward.

[0028] like Figure 2 and Figure 3 As shown, a rubber ring 5 is fixedly connected to the inner wall of the positioning groove of the metering rod 1, and the rubber ring 5 is arranged in a pair of positioning grooves. During operation, when the push rod 2 is inserted into the positioning groove of the inner wall of the metering rod 1, the push rod 2 contacts with the rubber ring 5, and the push rod 2 is squeezed and fixed in the positioning groove, and at the same time plays a buffering role. In this step, the push rod 2 is squeezed and fixed in the positioning groove by the setting of the rubber ring 5, which reduces the situation where the push rod 2 contacts the metering rod 1 and causes damage to the metering rod 1, thereby improving the stability of the device during use.

[0029] like Figure 1 As shown, the connecting sleeve 11 is fixedly connected to the inner wall near the metering rod 1 with a second suction cup 6. During operation, when the metering rod 1 is inserted into the end of the connecting sleeve 11, the second suction cup 6 contacts and adsorbs the end of the metering rod 1. In this step, the second suction cup 6 is arranged to form an adsorption and fixing structure, which improves the stability of the connection between the metering rod 1 and the connecting sleeve 11 and reduces the separation of the metering rod 1 and the connecting sleeve 11.

[0030] like Figure 4 As shown, the cone 22 is made of stainless steel. During operation, the cone 22 is made of stainless steel, which reduces the corrosion of the cone 22, increases the service life of the cone 22, and reduces the possibility that the cone 22 is rusted and causes the push rod 2 to get stuck.

[0031] During operation, when the metering rod 1 is connected to the connecting sleeve 11, the connecting key 13 is embedded in the key slot 12, and the connecting sleeve 11 is heated. After heating, the metering rod 1 is inserted into the end of the connecting sleeve 11 for connection. The connecting key 13 and the connecting sleeve 11 are made of the same material. When the device is subjected to hot and cold deformation, the connecting key 13 and the connecting sleeve 11 have the same expansion coefficient, so that the metering rod 1 and the connecting sleeve 11 always maintain a tight fit. When the connecting key 13 is installed in the key slot 12, the clamping assembly and the fixing assembly fix the connecting key 13 inside the key slot 12. After the connecting key 13 is installed inside the key slot 12, the cone 22 is pressed downward, and the cone 22 squeezes a pair of push rods 2 to both sides, so that the push rods 2 are inserted into the positioning grooves of the inner side walls of the metering rod 1. The first spring 21 is compressed. When replacing the connecting key 13, the cone 22 is pulled upward, and the first spring 21 pushes the push rod 2 out of the side wall of the metering rod 1, and then the connecting key 13 is removed from the key slot 12. When the connecting key 13 is placed in the key slot 12, the bottom of the connecting key 13 contacts with the first suction cup 31 and is adsorbed by the first suction cup 31, and the first suction cup 31 drives the guide rod 3 to slide downward and compresses the second spring 32. When the connecting key 13 is removed, the second spring 32 drives the guide rod 3 and the second spring 32 to reset. When the cone 22 is pulled out, the handle 41 is toggled to make the rotating rod 4 vertical at the top of the cone 22, and the handle 41 is clamped with a vise to pull the cone 22 upward. When the push rod 2 is inserted into the positioning groove of the inner side wall of the metering rod 1, the push rod 2 contacts with the rubber ring 5, and the push rod 2 is squeezed and fixed in the positioning groove, and at the same time plays a buffering role. When the metering rod 1 is inserted into the end of the connecting sleeve 11, the second suction cup 6 contacts and adsorbs the end of the metering rod 1. The cone 22 is made of stainless steel, which reduces the corrosion of the cone 22, improves the service life of the cone 22, and reduces the situation where the push rod 2 is stuck due to rust of the cone 22.
