1, please consult shown in Fig. 4,5,6 simultaneously, when nailing maching wears screw to bearing hole B and ring set C the time, though this nailing maching has a fixing propelling movement stroke through setting, but unavoidable small gap, the distance generation error (longer slightly) that screw is pushed of taking place in machinery action than the distance that sets; Again, nailing maching is when wearing screw, and the center line concentricity of its screw and ring set C must be same straight line, and when being placed through nonconcentric(al) screw in the ring set C with the nailing maching brute force, this ring set C must bear the strength that screw expands outwardly.Owing to ring set C be designed to thin-walled and closely coat screw do not have any nargin, so improper strength that when ring set C bears above-mentioned installing screw, is produced, this ring set C can or run through slotted eye D because of distortion and suffer oppression to produce and break, and make ring set C can't closely coat supporting screw, make screw present the state of deflection, and then influence the normal use of nailing maching.
2, for making screw when locking object, can break away from screw belt, this ring set C is provided with some slotted eye D that run through, so that screw makes it that ring set C impact extrusion is broken by the spinning strength of nailing maching, and then break away from screw belt, yet, because this ring set C is rounded, and the spinning strength that makes nailing maching is evenly distributed on the circumference of ring set C, so when the screw head shear spinning, often make the fracture of ring set C and body A joint, and depend on the screw neck, the shortcoming that causes screw to screw togather.
The purpose of this utility model promptly is to improve the above-mentioned shortcoming of commonly using the screw belt existence, and provide a kind of structurally improved screw belt, so that its ring set is designed to triangle, and make it have splendid ductility and covering property, and then when wearing screw, make ring set can play the effect of coating, supporting screw firmly.
For this reason, the utility model is taked following technological scheme:
A kind of structurally improved screw belt, it is to be provided with some bearing holes that can ccontaining screw head on a body, and the lower edge in this bearing hole extends a ring set, and be provided with some slotted eyes that run through in the appropriate location in bearing hole, this runs through slotted eye and extends to ring set and leave a suitable spacing with its bottom, its improvements are: described ring set is that a cross section is triangular in shape and have suitable thickness, and this wall is the hollow ring set with a suitable tapering, in addition, this runs through the position that slotted eye extends to ring set, be the middle position of this ring set triangle bending place, and leave suitable spacing with the ring set bottom.
The utility model preferred embodiment is described with reference to the accompanying drawings as follows:
Fig. 1 is for commonly using screw belt schematic perspective view ().
