The top of the mounting seat 2 is provided with a fixing block 201. The end of the mounting groove 101 close to the fixing block 201 is in an arc-shaped structure, which is convenient for the staff to quickly position the detection body 1 and improve the installation speed of the staff. Both sides of the fixing block 201 are in an arc-shaped structure. The arc-shaped structure can make the fixing block 201 and the outer surface of the detection body 1 on the same surface, increasing the detection body 1 and the fixing block 201. The aesthetic appearance of the fixing block 201 makes the device more coordinated and unified with the surrounding environment. The top of the fixing block 201 abuts against the bottom of the installation groove 101. A receiving groove 202 is provided inside the fixing block 201. A fixing mechanism for fixing the detection body 1 is provided inside the receiving groove 202. The fixing mechanism abuts against the fixing groove 102. A slide groove 203 is provided at the top of the receiving groove 202 inside the fixing block 201. The slide groove 203 is connected with the receiving groove 202. A sliding mechanism for fixing the detection body 1 with an auxiliary fixing mechanism is provided in the slide groove 203. The sliding mechanism is linked to the fixing mechanism.

[0026] In this embodiment, the fixing mechanism includes an extrusion block 204, a first pressure plate 205, a first elastic member 206, a slide rod 207, and several sliding components. The first elastic member 206 is a cylindrical compression spring. The cylindrical compression spring can make the device have better stability, adjustment ability and service life, while reducing costs and improving the economic benefits and reliability of the device. The extrusion block 204 is arranged on the top of the first pressure plate 205. The extrusion block 204 extends into the slide groove 203 and is provided with a first inclined surface 2041 slidably connected to the sliding mechanism. The top surface of the extrusion block 204 is an arc-shaped structure. The arc-shaped structure can improve the stability of the movement of the extrusion block 204 and the sliding mechanism.

[0027] The slide bar 207 is arranged at the bottom of the first pressure plate 205, the first elastic member 206 is sleeved on the slide bar 207, the bottom of the accommodating groove 202 is provided with a sliding groove 209, the slide bar 207 is slidably connected with the inner wall of the sliding groove 209, one end of the first elastic member 206 abuts against the bottom of the accommodating groove 202, and the other end of the first elastic member 206 abuts against the first pressure plate 205, and connecting plates 210 are provided on both sides of the first pressure plate 205, and sliding columns 211 are provided on the two connecting plates 210. The sliding columns 211 are linked with a plurality of sliding components, and the sliding components have at least 2, each sliding component includes a sliding block 212 and a fixed rod 213. A sliding groove 214 is provided in the sliding block 212, and the sliding groove 214 is tilted downward. The sliding column 211 is slidably connected with the sliding groove 214, and a guide groove 215 is provided on the side of the accommodating groove 202, and a guide block 216 is provided on the side of the sliding block 212. The guide block 216 is slidably connected with the inner wall of the guide groove 215 Then, the guide block 216 can effectively move the sliding block 212 within a certain range and prevent it from deviating from the normal working track, thereby increasing the stability of the entire structure. The fixed rod 213 is arranged at one end of the sliding block 212 away from the pressing block and extends to the outside of the fixed block 201. The fixed rod 213 abuts against the fixed groove 102. When the extrusion block 204 is subjected to the extrusion force and descends, the sliding rod 207 will slide on the inner wall of the sliding groove 209. At the same time, the extrusion block 204 will drive the first pressure plate 205 to descend. The first pressure plate 205 drives the sliding block 212 to move outward through the sliding column 211 on the connecting plate 210, thereby retracting the fixed rod 213. At this time, it is only necessary to dock the mounting groove 101 of the detection body 1 with the fixed block 201 to complete the installation. A third elastic member is provided between the two sliding blocks 212. The third elastic member is to ensure that when the staff releases the pressure rod 304, the fixed rod 213 can be extended to improve the stability of the device operation.

[0028] In this embodiment, the sliding mechanism includes a slider 3, a second elastic member 301, and a second pressure plate 302. The slider 3 is arranged inside the slide groove 203 and is slidably connected to the inner wall of the slide groove 203. The end of the slider 3 close to the extrusion block 204 is provided with a second inclined surface 3011 slidably connected to the extrusion block 204. The side of the slide groove 203 away from the accommodating groove 202 is provided with a compression groove 303. The second pressure plate 302 is arranged in the compression groove 303 and is fixedly connected to the slider 3. The second elastic member 301 is sleeved on the slider 3. One end of the second elastic member 301 abuts against the bottom of the compression groove 303, and the other end of the second elastic member 301 abuts against the second pressure plate 302. A pressure rod 304 is provided at the end of the second pressure plate 302 away from the slider 3. The pressure rod 304 passes through the side of the fixed block 201 and extends to the outside thereof. An opening 305 is provided on the side of the compression groove 303 away from the slider 3. A limit block 306 is provided at the opening 305 of the compression groove 303. The second pressure plate 302 abuts against the limit block 306. The limit block 306 can prevent the second pressure plate 302 from popping out when the second elastic member 301 is reset, thereby improving the stability of the structure. The pressure rod 304 has an arc-shaped structure at one end outside the fixed block 201. The arc-shaped pressure rod 304 design can better cooperate with the pressure of human fingers, making the operation more comfortable and natural.

[0029] Working principle: When the staff needs to install the detection body 1, first dock the mounting base 2 with the wall, press the pressure rod 304, and the pressure rod 304 will drive the second pressure plate 302 to move in the direction of compressing the second elastic member 301, thereby driving the slider 3 to move inside the slide groove 203. When the second inclined surface 3011 of the slider 3 contacts the first inclined surface 2041 of the extrusion block 204, the extrusion block 204 will be subjected to force and move in the direction of compressing the first elastic member 206. At the same time, the first pressure plate 205 will also drop, and pull the two sliding blocks 212 into the fixed block 201 through the sliding column 211 on the connecting plate 210, thereby retracting the fixing rod 213. At this time, it is only necessary to dock the mounting groove 101 of the detection body 1 with the fixed block 201 and release the pressure rod 304 to complete the quick installation of the detection body 1, which is convenient to operate.

[0030] When the staff needs to remove the detection body 1 for maintenance, they only need to press the pressing rod 304 and then directly take down the detection body 1, which is easy to operate.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
