DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] The present application embodiment discloses a lengthened bolt that is easy to position. Figure 1 , 2 , including a bolt body 1, a flower groove 2 is provided at the head of the bolt body 1, a thread 3 is provided at the tail of the bolt body 1, and a stabilizing structure 4 for assisting the bolt positioning connector on the opposite side of the nut is provided on the side of the bolt body 1 close to the head.

[0024] Reference Figure 1 , 2 The stabilizing structure 4 includes an abutment seat 41, a give-way groove 42, and a sliding sleeve 43. The give-way groove 42 is opened on the outer surface of the bolt body 1 close to the flower groove 2; the sliding sleeve 43 is sleeved and slidably connected to the give-way groove 42, and the outer diameter of the sliding sleeve 43 is the same as the outer diameter of the bolt body 1; the abutment seat 41 is fixed to the side of the sliding sleeve 43 close to the flower groove 2; and the abutment seat 41 vertically abuts against the surface of the connecting piece.

[0025] Reference Figure 1 , 2 The abutment seats 41 are arranged opposite to each other around the two sides of the bolt body 1, and the end of the abutment seats 41 away from the bolt body 1 is fixed with finger grooves 7 extending toward the side of the flower groove 2, and the side walls of the finger grooves 7 close to the bolt body 1 are bent inward; when the fingers are placed against the side close to the two finger grooves 7, the vertical connecting piece of the abutment seat 41 can be pressed and supported.

[0026] Reference Figure 2 , 3 A separation structure 5 for cutting the finger groove 7 is provided between the abutment seat 41 and the flower groove 2. The separation structure 5 includes a cutting protrusion 51 and a cutting groove 52. The cutting groove 52 extends in an annular shape and is opened on the abutment seat 41, and the cutting groove 52 gradually narrows from the side close to the thread 3 to the side close to the flower groove 2; the cutting protrusion 51 is arranged in an annular shape and sleeved on the bolt body 1, and the cutting protrusion 51 is arranged corresponding to the side of the abutment seat 41 close to the flower groove 2, and the cutting protrusion 51 is driven by the clamping structure 6 to cut the cutting groove 52.

[0027] Reference Figure 2 , 3The clamping structure 6 includes a clamping ring 61 and an extrusion ring 62. The clamping ring 61 is sleeved and fixed on the side of the sliding sleeve 43 close to the flower groove 2, and the side of the clamping ring 61 close to the thread 3 gradually tilts toward the flower groove 2 from the inside to the outside; the cutting protrusion 51 is fixed to the clamping ring 61; the extrusion ring 62 is sleeved on the bolt body 1 and is located between the flower groove 2 and the clamping ring 61, and the side of the extrusion ring 62 close to the thread 3 gradually tilts toward the flower groove 2 from the outside to the inside.

[0028] The working process of the present application is: insert the bolt body 1 and the sliding ring into the hole of the connecting piece, hold the finger groove 7 with fingers and press the abutment seat 41 on the surface of the connecting piece, adjust the sliding sleeve 43 to keep the bolt body 1 aligned, push the bolt body 1 to abut the nut of the connecting piece on the opposite side, rotate the flower groove 2, and the flower groove 2 gradually approaches the sliding sleeve 43.

[0029] When the flower groove 2 drives the extrusion ring 62 to abut against the extrusion ring 62, the extrusion ring 62 bends along the inner ring and drives the sliding sleeve 43 to deform, thereby transmitting stress between the bolt body 1 and the connecting piece, thereby increasing the fastening force; when the tightening ring 61 continues to tilt, it drives the cutting protrusion 51 to cut the cutting groove 52. At this time, the bolt is fixed, and the finger groove 7 falls off with the cutting of the cutting protrusion 51.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
