[0028] Fixed assembly 4 includes plug rod 401, the surface of mounting shell 1 is opened with annular groove 6, the inner wall of annular groove 6 is opened with mounting groove 7 and the number of mounting groove 7 is set to multiple, plug rod 401 passes through mounting groove 7 and extends to the inside of mounting shell 1, the top of plug rod 401 is fixedly connected with triangular block 402, reset spring 403 is sleeved on the surface of plug rod 401, and the both ends of reset spring 403 are fixedly connected with triangular block 402 and mounting groove 7 inner wall.

[0029] In the embodiment, the insertion rod 401 can pass through the mounting groove 7 of the mounting shell 1, and is inserted into the insertion slot 9 of the connecting barrel 8 of the packaging shell 3, so that the mounting shell 1 and the packaging shell 3 are fixedly connected. The inclined surface of the triangular block 402 is designed to move the insertion rod 401 to the side close to the insertion slot 9 under the extrusion of the limiting ring 501, so as to facilitate quick locking. The reset spring 403 provides a reset elastic force to drive the insertion rod 401 away from the insertion slot 9, so as to achieve the effect of quick unlocking. The annular groove 6 can provide a sliding track for the anti-disengagement assembly 5 such as the limiting ring 501 and the guide rod 502, so as to realize the integrated design of the fixing and anti-disengagement functions. The mounting groove 7 can limit the movement of the triangular block 402 and the insertion rod 401 in the axial direction only, so as to prevent the connection from loosening due to radial shaking. Meanwhile, the bottom of the mounting groove 7 can provide a fixed fulcrum for the reset spring 403, so as to ensure the direction of the elastic force.

[0030] Specifically, as shown in Figure 2 , Figure 6 , the limiting ring 501 is slidably connected to the surface of the annular groove 6, and the side of the limiting ring 501 close to the triangular block 402 is tightly attached to the triangular block 402.

[0031] Specifically, as shown in Figure 6 , a plurality of guide rods 502 are fixedly connected to the left side of the limiting ring 501 and are arranged in a ring shape, and the other ends of the guide rods 502 are movably connected to the inside of the mounting shell 1.

[0032] Specifically, as shown in Figure 6 , the left side of the limiting ring 501 is fixedly connected with a fastening spring 503, and the fastening spring 503 is sleeved on the surface of the guide rod 502. The other end of the fastening spring 503 is fixedly connected with the inner wall of the annular groove 6.

[0033] In the embodiment, through the above arrangement, after the limiting ring 501 slides to the surface of the triangular block 402, an annular blocking surface can be formed to limit the outward movement of the insertion rod 401 and prevent it from disengaging from the insertion slot 9. The guide rod 502 can limit the limiting ring 501 to slide only in the axial direction, preventing it from deviating or tilting in the circumferential direction, so as to ensure that it accurately covers the triangular block 402. Meanwhile, the plurality of guide rods 502 arranged in a ring shape can form a stable support structure to improve the deformation resistance of the limiting ring 501. The fastening spring 503 can provide an axial elastic force to keep the limiting ring 501 in close contact with the triangular block 402 at all times, compensate for the gap caused by vibration or material creep, and overcome the resistance of the fastening spring 503 to push the limiting ring 501 to unlock, thereby reducing the risk of accidental loosening.

[0035] Specifically, as shown in Figure 3 , Figure 4 , the inner wall of the mounting shell 1 is provided with a positioning groove 10, and the surface of the connecting cylinder 8 is fixedly connected with a positioning strip 11, which is used in cooperation with the positioning groove 10.

[0036] In this embodiment: through the above setting, the connecting cylinder 8 is the butt joint structure of the packaging shell 3 and the mounting shell 1, and the rigid connection between the packaging shell 3 and the mounting shell can be realized through the cooperation of the plug rod 401 and the plug groove 9. The plug groove 9 can be used in cooperation with the plug rod 401, so that the plug rod 401 is inserted into the inside, ensuring the relative position accuracy of the packaging shell 3 and the mounting shell 1. The positioning groove 10 can provide an accurate sliding path for the positioning strip 11, ensuring that the packaging shell 3 is smoothly inserted into the mounting shell 1 along the axial direction, and the positions of the two can be preliminarily fixed, improving the assembly efficiency.

[0037] Specifically, as shown in Figure 4 , the packaging shell 3 is fixedly connected with a sealing ring 12 on the side close to the mounting shell 1, and the side close to the mounting shell 1 of the sealing ring 12 is in close contact with the mounting shell 1.

[0038] Specifically, as shown in Figure 1 , the packaging shell 3 and the mounting shell 1 are both made of heat-conducting plastic material.
