[0028] The stirring mechanism includes a rotating handle 201, a spring 202, a sealing cover 203, a baffle 204, a rotating shaft 205, a spiral blade 206, a circular matching piece 207 and a fixed block 208. The rotating handle 201 is arranged on the top of the top cover 2, the fixed block 208 is fixedly connected to one side of the rotating handle 201, the rotating shaft 205 is fixedly connected to the bottom of the fixed block 208, the baffle 204 is fixedly connected to the outer surface of the rotating shaft 205, the sealing cover 203 is fixedly connected to the inner wall of the top cover 2, the spring 202 is arranged on the top of the baffle 204, and spring washers are arranged on the upper and lower sides of the spring 202. The spring washers play a role in protecting the supporting surface in the connecting piece, the spiral blade 206 is fixedly connected to the outer surface of the rotating shaft 205, and the circular matching piece 207 is rotatably connected to the bottom of the rotating shaft 205. Rotating the rotating handle 201 drives the rotating shaft 205 to rotate, and drives the spiral blade 206 to rotate. When the bottom of the receiving tube 1 is in a sealed state, rotating the rotating handle 201 in different directions will stir the coupling agent inside the receiving tube 1 to prevent it from precipitating inside the receiving tube 1.

[0029] The top of the accommodating tube 1 is provided with an external thread, and the inner wall of the top cover 2 is provided with an internal thread matching therewith. The internal and external threads cooperate with each other, and the top cover 2 can be screwed and fixed on the top of the accommodating tube 1.

[0030] Embodiment 2:

[0031] On the basis of the first embodiment, a smearing mechanism is arranged at the bottom of the accommodating tube 1, and the smearing mechanism includes a bottom bracket 101, a positioning column 102, a smearing cotton sheet 103, a fixing screw 104, a circular baffle 105 and a side handle 106. The bottom bracket 101 is fixedly connected to the bottom of the accommodating tube 1, the positioning column 102 is fixedly connected to the top of the bottom bracket 101, the smearing cotton sheet 103 is arranged at the bottom of the bottom bracket 101, the fixing screw 104 is threadedly connected to the bottom of the bottom bracket 101, and a threaded hole matching with the fixing screw 104 is opened at the bottom of the bottom bracket 101. The smearing cotton sheet 103 can be replaced by removing the fixing screw 104. The circular baffle 105 is arranged between the accommodating tube 1 and the bottom bracket 101. A groove matching with the circular matching piece 207 is opened at the top of the circular baffle 105. A through hole is opened through the bottom of the inner wall of the groove, and the coupling agent can flow out through the through hole in the groove. The side handle 106 is fixedly connected to one side of the circular baffle 105.

[0032] An observation port 3 is provided on one side of the receiving tube 1, and the observation port 3 can be used to observe the coupling agent capacity inside the receiving tube 1 and replenish the coupling agent in time.

[0033] Embodiment three:

[0034] On the basis of Embodiment 2, when the fixed block 208 is pulled upward, the baffle 204 will compress the spring 202, and the circular fitting 207 will move upward accordingly. When the circular fitting 207 leaves the top of the circular baffle 105, the side handle 106 is toggled to rotate the circular baffle 105 by 60° around its center line. At this time, the fixed block 208 is released. Under the action of the resilience of the spring 202, the circular fitting 207 moves downward. However, at this time, the gap part of the circular fitting 207 will be aligned with the through hole part of the circular baffle 105. In this way, the coupling agent inside the receiving tube 1 can pass through the circular fitting 207 and the circular baffle 105 in sequence from the bottom of the receiving tube 1 to reach the surface of the application cotton sheet 103. When the coupling agent soaks the application cotton sheet 103, the coupling agent attached to the upper end of the application cotton sheet 103 can be used for application at this time.

[0035] Rotating the rotating handle 201 clockwise will cause the rotating shaft 205 to drive the spiral blade 206 to rotate clockwise. Rotating the rotating shaft 205 clockwise compresses the coupling agent inside the receiving tube 1 downward to increase the liquid discharge rate of the coupling agent inside the receiving tube 1 as needed. Finally, the fixed block 208 is pulled upward to drive the fixed block 208 and the circular fitting 207 to move upward in sequence. When the circular fitting 207 moves to the top of the circular baffle 105, the side handle 106 is toggled to rotate the circular baffle 105 by 60° around its center line. The fixed block 208 is released, and under the action of the resilience of the spring 202, the circular fitting 207 rebounds and the circular fitting 207 is clamped with the circular baffle 105 again to seal the inside of the receiving tube 1.

[0036] Working principle:

[0037] First, the top cover 2 can be removed from the top of the receiving tube 1 by rotating the top cover 2, so as to add the coupling agent into the receiving tube 1, and then the top cover 2 is tightened.

[0038] Furthermore, through the arranged stirring mechanism, after rotating the rotating handle 201, the rotating shaft 205 can be driven to rotate, and the spiral blade 206 can be driven to rotate. When the bottom of the receiving tube 1 is in a sealed state, rotating the rotating handle 201 in different directions will stir the coupling agent inside the receiving tube 1 to prevent precipitation from occurring inside the receiving tube 1 and resulting in poor effects.

[0039] Further, through the provided smearing mechanism, when the fixing block 208 is pulled upward, the retaining piece 204 will compress the spring 202, and the circular fitting 207 will move upward accordingly. When the circular fitting 207 leaves the top of the circular baffle 105, the side handle 106 is toggled to rotate the circular baffle 105 by 60° around its center line. At this time, the fixing block 208 is released. Under the action of the resilience of the spring 202, the circular fitting 207 moves downward. However, at this time, the gap part of the circular fitting 207 will align with the through-hole part of the circular baffle 105. In this way, the coupling agent inside the receiving tube 1 can pass through the circular fitting 207 and the circular baffle 105 in sequence from the bottom of the receiving tube 1 to reach the surface of the smearing cotton sheet 103. When the coupling agent soaks the smearing cotton sheet 103, the coupling agent attached to the upper end of the smearing cotton sheet 103 can be used for smearing at this time.

[0040] Further, when the bottom of the receiving tube 1 is unsealed, clockwise rotation of the rotary handle 201 will cause the rotary shaft 205 to drive the spiral blade 206 to rotate clockwise. When the rotary shaft 205 rotates clockwise, the coupling agent inside the receiving tube 1 will be compressed downward, improving the liquid discharge rate of the coupling agent inside the receiving tube 1, and it can be adjusted as needed.

[0041] Further, when the fixing screw 104 is removed, the smearing cotton sheet 103 can be replaced. During actual use, repeated use can be avoided, improving the hygiene.

[0042] Furthermore, after the work is completed, the fixing block 208 is pulled upward, driving the fixing block 208 and the circular fitting 207 to move upward in sequence. When the circular fitting 207 moves to the top of the circular baffle 105, the side handle 106 is toggled to rotate the circular baffle 105 by 60° around its center line. After the fixing block 208 is released, under the action of the resilience of the spring 202, the circular fitting 207 rebounds. When the circular fitting 207 is re-clamped with the circular baffle 105, the sealing of the inside of the receiving tube 1 is completed.
