     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     A battery rod is provided in the application, and a hand feeling and a usage feeling of an electronic cigarette may be improved with the battery rob. In addition, an electronic cigarette having the battery rod is provided. 
     The application is further described in detail in conjunction with drawings and embodiments, for making a solution of the application better understood by those skilled in the art. 
     Reference may be made to  FIG. 1  and  FIG. 2 .  FIG. 1  is a section view of an assembling structure of a battery rod according to an embodiment of the application; and  FIG. 2  is an enlarged schematic view of section A in  FIG. 1 . 
     In the embodiment, the battery rod provided in the present application may be assembled with an atomizer to form an electronic cigarette. The battery rod includes a battery cartridge, and a connector  16  provided at the inside of one end of the battery cartridge and connected to the atomizer. The battery cartridge includes an inner protective cartridge  112  and an outer protective cartridge  113  which are coaxially arranged, where the inner protective cartridge  112  is arranged inside and the outer protective cartridge  113  is arranged outside. Both the inner protective cartridge  112  and the outer protective cartridge  113  are parts made of a non-metallic material. At a position corresponding to the position of the connector  16 , a fastening ring  18  for clamping the connector  16  is sleeved on the outside of one end of the inner protective cartridge  112 . The outer protective cartridge  113  and fastening ring  18  are coaxially arranged, and the outer protective cartridge  113  and fastening ring  18  are staggered in an axial direction of the battery cartridge. One end surface of the outer protective cartridge  113  faces one end surface of the fastening ring  18 . 
     With an arrangement of the above structure of the application, the connector  16  is avoided from falling off, and the battery cartridge made of the non-metallic material touches soft and comfortable, and a hand feeling of a cigarette may be well simulated, thereby greatly improving an overall simulation degree of the electronic cigarette and significantly optimizing the user experience. Furthermore, the outer protective cartridge  113  and the fastening ring  18  are coaxially provided and are located at different positions in the axial direction of the battery cartridge, and one end surface of the outer protective cartridge  113  faces one end surface of the fastening ring  18 ; hence, a corresponding coating structure coated on the outer protective cartridge  113  and the fastening ring  18  may be avoided from being damaged due to an external force, thereby lengthening the service life of the electronic cigarette. 
     Further, an outer circumferencial surface of the outer protective cartridge  113  and an outer circumferencial surface of the fastening ring  18  are flush with each other. With the structure that the outer circumferencial surface of the outer protective cartridge  113  and the outer circumferencial surface of the fastening ring  18  are flush with each other, an outer structure of the electronic cigarette may be further optimized, the battery rod is avoided from an uneven outer surface, and accordingly, the user experience is further improved. In addition, the corresponding structure coated on the outer protective cartridge  113  and the fastening ring  18  may be avoided from being damaged by the external force, and a user is avoided from being hurt by the fastening ring during usage. Besides, with the above structure, outer surfaces of electronic cigarettes placed together may be closely abutted against each other; hence, scratchings between the electronic cigarettes, falling of electronic parts and oil leaking of the atomizer, which are caused by vibration when the electronic cigarettes are transported or are put in a pocket of a user, are avoided. 
     Specifically, a coating layer  111  is provided on the outer circumferencial surface of the outer protective cartridge  113  and the outer circumferencial surface of the fastening ring  18 . The coating layer  111  may further ensure a flatness of an outer circumferencial surface of an assembling structure between the battery cartridge  11  and the connector  16 , thereby further optimizing an overall outer structure of the electronic cigarette. 
     More specifically, the coating layer  111  is a paster. With a low procurement cost, a huge quantity of market supply, and an excellent bonding and fixation effect, the paster may meet assembling requirements of the electronic cigarette and the production cost of the electronic cigarette is effectively reduced. With the coated paster, the electronic cigarette having the battery rod further looks like the cigarette, thus improving the user experience. 
     On another hand, both the inner protective cartridge  112  and the outer protective cartridge  113  are parts made of a non-metallic material having a hardness smaller than that of copper. With the parts made of a soft material having a small hardness, the whole hand feeling of the electronic cigarette may be further optimized, and the user experience is better. 
     Furthermore, the battery cartridge  11  may be any one of a plastic part, a rubber part and a paper part. Of course, the battery cartridge  11  is not restricted to the plastic part, the rubber part and the paper part as long as practical usage requirements of the electronic cigarette may be satisfied. 
     Further, the fastening ring  18  is a part made of a metallic material such as copper, iron, steel or the like, and the structure strength and tenacity of the metallic material are better than those of a non-metallic material; hence, it is ensured that the fastening ring  18  may not be torn easily during assembling. Therefore, with a cooperation of the fastening ring  18  made of the metallic material and the battery cartridge  11  made of the non-metallic material, advantages such as a steady and reliable battery rod structure, a high product yield, a small overall weight and a high similarity to the cigarette may be realized.
