Drawings
Fig. 1 is a view showing a state in which the multifunctional portable bolt-fastening device of the present invention is used.
Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 1, the multifunctional portable bolt-fastener of the present invention comprises: the fixing frame comprises a triangular fixing frame 1, wherein an accommodating space for accommodating a bolt is defined in the fixing frame 1, a plurality of adjustable screw rods 2 are arranged on the fixing frame 1 in a centrosymmetric manner through fixing nuts 3, the outer sides of the fixing nuts 3 are fixed with the fixing frame 1, and the axes of the fixing nuts 3 are aligned to the symmetric centers of the adjustable screw rods 2.
When the fastener is used, the fixing frame 1 is arranged at the periphery of the hexagon bolt 5, the hexagon bolt 5 is positioned at the center of the fixing frame 1, three sides of the upper part of the hexagon bolt 5 are tightly propped through the adjustable screw 2 according to the diameter of the hexagon bolt 5, the opposite outer end of the adjustable screw 2 is held by two hands to rotate clockwise or anticlockwise, the hexagon bolt 5 is fastened or loosened, and force is needed to be exerted on the same horizontal plane when the bolt is rotated, so that the bolt does not incline. Triangular fixed frame 1 stability is good, is difficult for damaging when using, and trilateral top through adjustable screw 2 to hex bolts 5 reduces the risk of landing.
Preferably, the length of the adjustable screw 2 is greater than the distance of the fixed nut 3 from the centre of symmetry.
The length of the adjustable screw 2 enables a constructor to fasten the hexagon bolt 5 from the outside of the fixed frame 1, and then the constructor can apply force by means of the fixed frame 1 and apply the force to the hexagon bolt 5.
Preferably, the number of adjustable screws 2 is three.
In this embodiment, the fixing nuts 3 are fixed to three corners of the upper top surface of the triangular fixing frame 1, the adjustable screws 2 are screwed into the fixing nuts 3, and the number of the adjustable screws 2 is three, so that the stability is better, and the deformation resistance effect is good.
Preferably, the number of the fixing nuts 3 on each of the adjustable screws 2 is two.
When the adjustable screw 2 abuts against the hexagon bolt 5, the two fixing nuts 3 are screwed together to fix the position of the adjustable screw 2, so that the adjustable screw 2 and the hexagon bolt 5 are prevented from loosening, and then the hexagon bolt 5 is fastened or disassembled.
Preferably, the fixed frame 1 is in the shape of an equilateral triangle.
Equilateral triangle makes the center of fixed frame 1 equal to the distance of every angle to make the adjustable screw 2 length between 3 to the hex bolts of fixation nut equal, thereby make every adjustable screw 2 atress even, not fragile binding increases the life-span of binding.
Preferably, a handle 4 is fixed to the outer end of the adjustable screw 2 away from the center of symmetry.
When the rotary fastening or loosening operation is carried out, the handle 4 is directly held by the hand to apply force, so that the operation is more convenient, and the hand holding is more comfortable.
Preferably, the fixing frame 1 is a square aluminum tube.
The square aluminum pipe is high in strength, not prone to rusting and long in service life.
According to the utility model, the bolt is fastened through the fixing frame and the adjustable screw jacking bolt, so that the technical problem that the hexagon bolt is easy to slide in the fastening process in the prior art is solved. The utility model accelerates the construction speed of the fastening bolt in the installation process of the steel pipe column, has simple manufacture, simple used materials and lower cost than the price of a conventional wrench, and the fastener is not easy to slide, reduces the collision with the bolt, ensures the stable operation of hands and greatly reduces the safety risk.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
