Sawtooth steps are arranged on two sides of the pressing block 131, and a pressing groove is formed in the pressing block and used for pressing the optical cable in the pressing groove; the fixing block 132 is arranged between the pressing block 131 and the box body 1 and fixed on the box body 1, and the pressing block 131 can slide in the fixing block 132; the locking unit 14 is movably arranged on the fixing block 132, one end of the locking unit is positioned on one side of the fixing block 132, which is far away from the pressing block 131, and the other end of the locking unit is in contact with the upper top surface of the sawtooth step and is used for fixing the pressing block 131 in the fixing block 132; the two sides of the pressing block 131 are provided with the saw-toothed structure, the upper end of the saw tooth is a plane, the lower end is an inclined plane inclined from two sides to the middle, the fixing block 132 is provided with the locking unit 14, the pressing block 131 is pressed downwards, the inclined plane at the lower end of the saw-toothed structure of the pressing block 131 contacts with the locking unit 14, the locking unit 14 moves outwards, when the locking unit 14 contacts with the plane at the upper end of the saw tooth, the locking unit 14 moves inwards, the pressing block 131 cannot move like an upper plane due to the contact with the upper plane, the optical cable is compacted below the pressing block 131 through the downward movement of the pressing block 131, the pressing block 131 is fixed on the fixing block 132 through the abutting of the locking unit 14, the effect of pressing and fixing the optical cable is achieved, the effect of fixing the optical cable can be achieved by pressing the pressing block 131 in the fixing process, unnecessary trouble of fixing by, the operation is simple and quick.

As a specific embodiment of the system for detecting and controlling carbon dioxide in flue gas by directly utilizing the internet of things provided by the present invention, please refer to fig. 1 and 4, the locking unit 14 includes a locking pin 141, a third elastic member 142 and a handle 143. The locking pin 141 is movably arranged on the fixed block 132, one end of the locking pin is positioned outside the fixed block 132, and the other end of the locking pin can be abutted against the upper top surface of the sawtooth step; the third elastic element 142 is disposed between the fixed block 132 and the locking pin 141, and is used for driving the locking pin 141 to move towards the pressing block 131; and a handle 143 is disposed at an end of the locking pin 141 remote from the pressing block 131 for pulling the locking pin 141 to slide in the fixing block 132. The third elastic member 142 pushes the locking pin 141 to move towards the direction of the pressing block 131 all the time in the downward pressing process of the pressing block 131, so that the locking pin 141 is in contact with the upper plane of the saw teeth on the pressing block 131, the effect of automatically fixing the pressing block 131 on the fixing block 132 is achieved, when the pressing block 131 needs to be pulled out of the fixing block 132, the locking pin 141 is pulled to move towards the direction away from the pressing block 131 through the handle 143, so that the locking pin 141 is separated from the upper plane of the saw teeth, the pressing block 131 can be pulled out of the fixing block 132 through simple operation, the optical cable is disassembled or rearranged and installed, the end part of the locking pin 141 in the fixing block 132 is provided with a chamfer, and is arranged in parallel to the inclined plane arranged on the pressing block 131; the locking pin 141 is of a square structure inside the fixed block 132, and a square hole corresponding to the locking pin 141 is formed inside the fixed block 132, so that the locking pin 141 can be prevented from rotating inside the fixed block 132 to enable the chamfer on the locking pin 141 to be always parallel to the inclined plane on the pressing block 131.

In this embodiment, the third elastic member 142 is a spring, which is cheap, reduces the production cost of the fiber coiling box, and has good stability.

As a specific embodiment of the fiber coiling box provided by the present invention, please refer to fig. 1, the fiber coiling box further comprises a fastening unit 15. The fastening unit 15 is disposed between the case 1 and the cover 2, and is used to lock the case 1 and the cover 2. Be provided with the screw via hole in the outside of lid, be provided with the screw hole in the outside of box body 1 and the position that the screw via hole corresponds, pass the screw via hole that sets up on the box body 1 through the screw after the lid covers box body 1 and twist the screw hole that sets up on box body 1 and be connected lid and box body 1 and tighten, easy operation, it is fixed effectual.

Referring to fig. 1, the fiber coiling box further includes a signal lamp 7, a power supply 8, a conductive rod 9, and a conductive block 10. The signal lamp 7 penetrates through the box body 1; the power supply 8 is arranged in the box body 1 and used for supplying electric quantity to the signal lamp 7; the conducting rod 9 is arranged at the end part of the sliding block 32, can slide together with the sliding block 32 in the guide chute 31, and is electrically connected with the power supply 8; the conducting block 10 is arranged at one end of the conducting chute 31 close to the wire inlet 101 and is electrically connected with the signal lamp 7, and a closed loop used for lightening the signal lamp 7 is formed when the conducting rod 9 is contacted with the conducting block 10; the power supply 8 is fixed in the box body 1, one of the positive pole and the negative pole of the power supply 8 is electrically connected with the conductive rod 9, one end of the conductive rod 9 is fixed on the slide block 32, the other end of the conductive rod 9 is provided with a conductive sleeve in the conductive chute 31, the conductive rod 9 slides in the conductive sleeve and is electrically connected with the conductive sleeve, the power supply 8 is electrically connected with the conductive sleeve, so that the power supply 8 is electrically connected with the conductive rod 9, the other pole is electrically connected with one pole of the signal lamp 7, one end of the conductive rod 9 is fixed on the slide block 32, the conductive block 10 is arranged in the conductive chute 31 and is close to one end of the wire inlet 101, the conductive block 10 is electrically connected with the other pole of the signal lamp 7, when the shrinkage of the optical cable is too large, the movable winding disc 4 is driven to move to a certain position towards the wire inlet, when the other end of the conductive rod 9 is contacted with, the messenger patrols and examines personnel in the scene and can in time discover that the optical cable length in this box body 1 is not enough, needs rewiring, thereby prevents to continue to contract in box body 1 and take place the fracture in following box body 1 because ambient temperature continues to become low and lead to the optical cable in the box body 1.
