Abstract
The utility model discloses a narrow rotating space bolt fastening device, and belongs to the technical field of portable motor-driven tools for loosening or fastening nuts. A main body of the narrow rotating space bolt fastening device comprises a spindle and split bolt clamp sleeves, a one-way spanner perpendicular to the spindle is mounted in the middle of the spindle, a ratchet mechanism is arranged at the joint of the one-way spanner and the spindle, a baffle is arranged at one end of the spindle, a spline connecting shaft is arranged at the other end of the spindle and connected with the bolt clamp sleeve through a spline, an inner spline matched with the spline connecting shaft is arranged at one end of the bolt clamp sleeve, and a hexagonal sleeve hole is formed in the other end of the bolt clamp sleeve. The narrow rotating space bolt fastening device cannot be limited by spaces and angles, and bolts and nuts are easily loosened or fastened.
Description
Technical field
The utility model relates to a kind of bolted instrument, belongs to unclamp or the portable power tools technical field of clamp nut.
Background technology
Bolt and nut component is widely used in the connection of various device, but in some cases, such as in the space that groove, hole or gusset are arranged, can form narrow and small revolution space, is unfavorable for that very common spanner unclamps or clamp nut.Because the lattice of bolt both sides retaining distance is very near, the rotatable angle of common spanner is too little, is difficult to launch construction, has seriously reduced operating efficiency.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of narrow and small revolution space bolt clamp device, can not be subjected to the restriction of space angle, easily unclamps or the work of fastening bolt nut.
The utility model is achieved by the following technical solution: a kind of narrow and small revolution space bolt clamp device is characterized in that: its main body is made up of main shaft and the bolt cutting ferrule that splits; The middle part of described main shaft is equipped with the lug wrench vertical with main shaft, and the junction of lug wrench and main shaft is ratchet mechanism; One end of described main shaft is provided with baffle plate, the other end of main shaft is provided with the spline connecting axle, spline connecting axle spline connects described bolt cutting ferrule, and an end of bolt cutting ferrule is manufactured with the internal spline suitable with the spline connecting axle, and the other end of bolt cutting ferrule is manufactured with the hexagonal trepanning.
Be manufactured with anti-skidding rag on the described lug wrench.
The beneficial effects of the utility model are:
1, the utility model is owing to be not directly to exert all one's strength at bolt, and lug wrench is vertical with main shaft, so in narrow and small revolution spaces such as groove, hole or sheet with rib, can not be subjected to the restriction of space angle, easily unclamps or the work of fastening bolt nut.Adopt the ratchet one-way spanner in addition, make action that continuity more be arranged, flexible and efficient.
2, simple in structure, easy and simple to handle, laborsaving, be convenient to promote.
Description of drawings
Further specify with the utility model of embodiment with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation.
Among the figure, 1, lug wrench, 1-1, anti-skidding rag, 2, main shaft, 3, the spline connecting axle, 4, the bolt cutting ferrule, 5, the hexagonal trepanning.
The specific embodiment
A kind of narrow and small revolution space bolt clamp device shown in Figure 1 as accompanying drawing, its main body is made up of main shaft 2 and the bolt cutting ferrule 4 that splits; The middle part of described main shaft 2 is equipped with the lug wrench vertical with main shaft 1, and lug wrench 1 is ratchet mechanism with the junction of main shaft 2; One end of described main shaft 2 is provided with baffle plate, the other end of main shaft 2 is provided with spline connecting axle 3, spline connecting axle 3 splines connect described bolt cutting ferrule 4, and an end of bolt cutting ferrule 4 is manufactured with the internal spline suitable with spline connecting axle 3, and the other end of bolt cutting ferrule 4 is manufactured with hexagonal trepanning 5.
Be manufactured with anti-skidding rag 1-1 on the described lug wrench 1.
During use, bolt cutting ferrule 4 is enclosed within on the bolt to be tightened, hexagonal trepanning 5 just in time blocks the nut of bolt, then, main shaft 2 is installed on the bolt cutting ferrule 4, and in the internal spline of spline connecting axle 3 inserting bolt cutting ferrules 4, main shaft 2 blocks bolt cutting ferrule 4; At this moment, main shaft 2, bolt cutting ferrule 4 is on the same axis with bolt to be tightened, rotates lug wrench 1 then, drives main shaft 2 simultaneously, bolt cutting ferrule 4 rotates with nut to be tightened, until with bolted.Because adopt ratchet mechanism, main shaft is only done unidirectional rotation, the reciprocally swinging with lug wrench 1 does not turn round, thus do not need the utility model and nut are broken away from, but continuous action.Finish using, main shaft, bolt cutting ferrule 4 and bolt to be tightened are broken away from successively get final product.Bolt cutting ferrule 4 can have different models.
