The invention discloses a gas leak detection gun head. The gas leak detection gun head comprises a butt-joint head, a main gas adsorption pipe and an auxiliary gas adsorption pipe; an included angle is formed between the axis of the main gas adsorption pipe and the axis of the auxiliary gas adsorption pipe; and therefore, the gas leak detection gun head can adsorbed gas from different directions and in different angles during a detection and sampling process, so that a detection coverage can be extended. With the gas leak detection gun head adopted, barriers brought about by a single-pipe typedetection gun head are eliminated; and multi-directional wrapping detection on a pipeline can be realized, so that detection accuracy can be improved. The invention also discloses a gas leak detection device provided with the above gas leak detection gun head. 本发明公开了种气体检漏枪头，包括对接头、主吸气管和辅吸气管，并且主吸气管的轴线与辅吸气管的轴线有夹角，从而可实现该气体检漏枪头在检测取样时为多方向多角度吸附气体进行分析检测，增大了检测覆盖面。该气体检漏枪头打破了单管式检测枪头的壁垒，对管道形成多方位包裹式检测，提高了检测的准确性。本发明还公开了种具有上述气体检漏枪头的气体检
