This invention relates to the field of gas chromatography technology, specifically to a high-sensitivity GC-PDECD gas chromatograph, comprising a gas chromatograph body, a display fixedly connected to the surface of the gas chromatograph body, and a heat dissipation structure on the outer wall of the gas chromatograph body. The heat dissipation structure includes an air pump, which is fixedly connected to the gas chromatograph body. By setting up the heat dissipation structure, during sample detection by the gas chromatograph, heat from the hot air is conducted to the inlet pipe, which in turn conducts heat to the heat sink. The heat sink dissipates the heat outward, thereby reducing the temperature of the air in the inlet pipe. The air pump then delivers the air through the exhaust pipe into the gas chromatograph body, further reducing the temperature within the gas chromatograph body. This prevents interruptions during gas chromatograph operation, thereby improving the sensitivity of the gas chromatograph and ultimately increasing detection efficiency.

The utility model relates to cutting equipment technical field, specifically disclose a cutting device for ETFE film processing, including work table, the upper end tail portion of work table is installed with pressing mechanism, the pressing mechanism includes C shaped board, the opposite two inner walls of C shaped board rotatory mounting have cylinder, the upper end rear portion of work table is installed with support frame, the middle part of support frame is vertically slid down and is installed with rack, the lower extreme of rack is connected with the top of C shaped board, the long rod of connection is located in the inside of support frame, and one end rotatory mounting is in the side wall of support frame, and is connected with the output of drive assembly, and the other end is installed with gear, the gear is engaged with rack. The utility model can realize the adjustment of cylinder and work table interval, and ETFE film is laid on the work table, and the cylinder is lowered to contact the film material surface with C shaped board, and the cylinder realizes line contact type pressure through self rotation, and the pressure is evenly distributed on the film material surface, and the ETFE film edge indentation is eliminated.

This utility model belongs to the technical field of surveillance camera brackets, and mainly relates to a quick-installation bracket for surveillance cameras. It includes a support rod at the top for holding the surveillance camera, and multiple legs at the lower end of the support rod for stabilizing it. A battery is detachably arranged on the support rod between any two adjacent legs, and the battery is electrically connected to the surveillance camera to supply power. Because the battery is removable, multiple batteries can be equipped in actual use. When one battery is low on power, it can be quickly replaced with a fully charged battery, achieving "seamless operation" and completely solving the problem of insufficient battery capacity of the surveillance camera itself.
