Zusammenfassung:	The utility model discloses an auxiliary fixing device for drilling in a catenary tunnel, which belongs to the technical field of railway catenaries and comprises a fixing support, a lifting component arranged on the fixing support and a traction component connected with the lifting component. Wherein the fixed bracket comprises a first bracket and a second bracket; the lifting assembly comprises a connecting pipe and a supporting piece connected with the connecting pipe. The connecting pipe is arranged on the first support and the second support in a sleeving mode, and the two sides of the supporting piece are connected with the connecting pipe. The technical problems that construction errors exist, the construction efficiency is low and the personal safety of constructors cannot be guaranteed when the electric hammer is held by hand for construction are solved, and the technical effects that the drilling qualified rate and the construction efficiency are improved, and the personal safety of the constructors
