[0024] The detailed connection means is a known technology in the art, and the working principle and process are mainly introduced as follows:

[0025] According to the description attached Figures 1-6It is known that the utility model is most suitable for being used in the case that the carrier 1 mounting groove 2 is downward, the mounting groove 2 at the bottom of the carrier 1, the base 3, the plurality of clamping bodies 10 and the mounting plate 4 are set in advance and exist in a complete set when installing for the first time, the base 3 is installed in the mounting groove 2 of the carrier 1, and the mounting plate 4 is fixed with the carrier 1 through the expansion nail 13, and subsequent maintenance and replacement do not need to be disassembled; the fixing disc 15 at the top of the composite detector 14, the bottom disc 16, the connecting column 17, the fixed conical table 20 and the movable conical table 18 are also installed in advance and exist in a complete set, and subsequent maintenance and replacement do not need to be disassembled; the personnel vertically upwardly insert the fixed conical table 20 into the groove 5 of the base 3 by holding the composite detector 14, in the process, the fixed conical table 20 extrudes the plurality of clamping bodies 10, the clamping body 10 is provided with a slope and the slope is downward and the normal vector is inward, therefore, the clamping body 10 can be moved radially into the limiting groove 6 under extrusion, so that the first compression spring 11 is compressed, as shown in Figure 3 The limiting rod 8 moves stably under the limiting action of the mounting ring 7, the fixed conical table 20 continues to move upward, the movable conical table 18 falls on the bottom disc 16 due to gravity, therefore, a gap appears between the fixed conical table 20 and the movable conical table 18, after the bottom surface exceeds the upper surface of the clamping body 10, the force of the first compression spring 11 pushes the clamping body 10 to move between the fixed conical table 20 and the movable cylindrical table, the clamping plate 9 is blocked by the mounting ring 7, the clamping body 10 stays in the gap, the upper surface of the clamping body 10 supports the fixed conical table 20, and the installation is completed. When maintenance and replacement are needed, the composite detector 14 needs to be disassembled, the personnel continue to push the composite detector 14 upward, the bottom disc 16 supports the movable conical table 18 and moves upward, the clamping body 10 is provided with a slope and the slope is downward and the normal vector is inward, the large bottom surface (upper bottom surface) of the movable conical table 18 contacts the slope of the clamping body 10 and extrudes the clamping body 10 to move radially, the principle is the same as that of the fixed conical table 20 extruding the clamping body 10, until the bottom surface of the clamping body 10 is lower than the lower bottom surface of the movable conical table 18, then the personnel move the composite detector 14 downward, that is, pull out outward, as shown in Figure 4 Due to the force of the first compression spring 11, the upward force of the clamping body 10 to the side surface of the movable conical table 18 is greater than the gravity of the movable conical table 18, therefore, the upper surface of the movable conical table 18 can contact the lower bottom surface of the fixed conical table 20, and there is no gap, as shown in Figure 5 The personnel continue to move the composite detector 14 downward, the contact between the clamping body 10 and the side surface of the movable conical table 18 directly changes into the contact with the surface of the fixed conical table 20, as shown in Figure 6As shown, the composite detector 14 can be disassembled. After the first installation of the base 3 (similar to the first installation of the prior art, mainly in the subsequent disassembly and installation), the subsequent composite detector 14 is installed and disassembled by plugging, without the need for tools, without damaging the composite detector 14 or the carrier 1, simple and convenient operation, greatly improving the work efficiency, here, the personnel inserts the fixed conical table 20 upward, which needs to master the force. It should be noted that in the utility model, the arrow direction in the description Figures 3-6 The arrow direction in the description represents the force direction of the personnel on the composite detector 14, and the personnel needs to pay attention to the insertion depth during installation. The insertion depth of the first level (i.e. the fixed conical table 20) is installation, and the insertion depth of the second level (i.e. the movable conical table 18) is disassembly. The personnel can also refer to the sound of the clamping body 10 rebounding under the action of the first compression spring during insertion. The first sound is installation, and the second sound is disassembly. Those skilled in the art can understand the above installation skills.

[0026] Among them, the bottom of the groove 5 is provided with a plurality of second compression springs 23, and the plurality of second compression springs 23 are fixedly connected with a pressing plate 24, and the pressing plate 24 is located in the groove 5, as Figure 2 As shown, the second compression spring 23 is extruded after the fixed ring is inserted, and the force makes the pressing plate 24 press fit on the fixed conical table 20, and cooperates with the support of the plurality of clamping bodies 10 to make the fixed conical table 20 and the composite detector 14 stable.

[0027] Among them, the gap between the installation plate and the composite detector 14 is filled with a rubber plug 22, which prevents debris from entering between the composite detector 14 and the installation plate 4. At the same time, the rubber plug 22 has a certain spring force, which can also extrude the composite detector 14 downward, and cooperate with the support of the clamping body 10 on the fixed conical table 20 to make the fixed conical table 20 and the composite detector 14 stable.

[0028] Among them, the end of the clamping body 10 corresponding to the inner side of the groove 5 is provided with a round corner, which avoids scratching the side surface of the movable conical table 18 by the sharp edge of the clamping body 10.

[0029] In addition, the base 3 and the installation plate 4 are fixedly connected by the first screw 12, and the installation plate 4 and the base 3 can also be disassembled, so that the first compression spring 11 and the clamping body 10 in the limiting groove 6 and other components can be replaced.

[0030] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
