The embodiment of the utility model is shown in fig. 1 and fig. 2, a positioning device, which comprises a positioning pin 1 and a pin sleeve 2 detachably matched with the positioning pin 1, when in use, the positioning pin 1 firstly passes through a part to be positioned, then the pin sleeve 2 is sleeved on the positioning pin 1 for positioning and fixing, the positioning pin 1 comprises a positioning pin cover 10 and a positioning pin rod 11 fixedly connected on the positioning pin cover 10 and in a cylinder structure, the positioning pin cover 10 and the positioning pin rod 11 are integrally formed by iron materials, the positioning pin cover 10 can be set into different shapes according to different requirements, such as triangle, quadrangle, circle, ellipse, etc., or a cross rod vertically arranged with the positioning pin rod 11, the positioning pin rod 11 can be selected into a cylinder or a square cylinder, preferably into a cylinder structure, the cylinder structure facilitates the cylinder structure to receive smaller resistance in the puncturing process, convenient puncture, the one end that locating pin pole 11 kept away from locating pin lid 10 is provided with the conical head 12 that becomes the centrum structure with locating pin pole 11 integrated into one piece, and conical head 12 just makes things convenient for it to insert in the part of awaiting the location, locating pin pole 11 is provided with pin pole recess 3 along locating pin pole 11 is radial in the position adjacent with conical head 12, and pin pole recess 3 can set up one or more according to different situation, and pin pole recess 3 is in locating pin pole 11 footpath and along locating pin pole 11 circumference setting, just means that setting up of pin pole recess 3 diminishes the thickness of locating pin pole 11 of this position department, just conveniently buckles conical head 12 in this position department during the use. In order to facilitate the bending of the conical head 12, the depth of the pin groove 3 is not greater than the radius of the positioning pin 11, so that the strength of the positioning pin 11 is not reduced. When the positioning pin is used, one end of the box body is pierced through the conical head 12 and inserted into the box body, the conical head penetrates out from the other end of the box body, the positioning pin cover 10 is abutted against one end of the box body, the conical head 12 is exposed out of the other end of the box body, then the pin sleeve 2 is sleeved on the positioning pin rod 11, and finally the conical head 12 is bent, so that the conical head 12 is abutted against the pin sleeve 2 to be fixed, the pin sleeve 2 and the positioning pin cover 10 are arranged at two opposite ends, the axial movement of the positioning pin rod 11 after positioning is avoided, meanwhile, the conical head 12 is abutted against the pin sleeve 2 after being bent, the loosening of a positioning structure on a horizontal plane is avoided, the positioning structure is firm, the loosening cannot be generated, and the positioning effect is ensured. The distance of the pin rod groove 3 from the positioning pin cover 10 is correspondingly set according to the height of the box body to be penetrated. In order to meet different use requirements, the pin rod grooves 3 are formed in the positioning pin rod 11, the pin rod grooves 3 can be arranged in parallel or staggered at intervals from a position adjacent to the conical head 12 to the positioning pin cover 10 along the axial direction of the positioning pin rod 11, and the pin rod grooves 3 can also be arranged on the positioning pin rod 11 in a threaded structure, so that the pin rod grooves 3 are formed in positions which are different in distance from the positioning pin cover 10, positioning of components with different thicknesses can be met, the positioning pin rod 11 is arranged in a staggered mode, namely the positioning pin rod grooves are correspondingly arranged at different positions in the circumferential direction of the positioning pin rod 11, the strength of the positioning pin rod 11 cannot be weakened, and the positioning pin rod 11 can be suitable for positioning with different thicknesses under the condition of ensuring the strength.
