Abstract

The utility model relates to the field of hardware and provides a wrench. The wrench includes a handle, a bending connecting rod, and a nut socket, and the handle and the nut socket are respectively connected at the two ends of the bending connecting rod. When a viaduct anti-throwing wire screen is installed, a nut to be screwed can be arranged in the nut socket in advance, one can hold the handle to penetrate the nut socket through a mesh and to align with the end of a screw rod, and then uses a common wrench to tightly screw the tail end of the screw rod to tightly lock the screw rod with the nut, so that the problems that the nut and the screw rod are difficult to install because of small mesh size when the wire screen is installed can be solved. By using such a wrench, operators don't have to conduct the operation by climbing over to the outer side of the viaduct, thereby reducing the danger of high altitude construction and improving the work efficiency.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Fig. 1 ~ Fig. 7, a kind of spanner 100 of the utility model, comprises handle 10, bending connecting rod 20 and ut socket 30, and handle 10 and ut socket 30 are connected to the two ends of bending connecting rod 20.As shown in Figure 6 and Figure 7, when the anti-throwing silk screen 400 of overpass is installed, can in advance need be twisted to solid nut 300 is placed in ut socket 30, then hand-held handle 10 passes and aims at screw end head by ut socket 30 from mesh, then adopt common wrench to twist solid screw rod tail end, make screw rod 200 and nut 300 lockings, thereby while having solved silk screen 400 installation, because size of mesh is little, cause nut 300, screw rod 200 to be difficult to the problem of installing, personnel are without turning over to outside operation, reduce the danger of work high above the ground, and improve operating efficiency.

In embodiment as depicted in figs. 1 and 2, bending connecting rod 20 comprises the first connecting rod 21 being connected with ut socket 30 and the second connecting rod 22 being connected with handle 10, and first connecting rod 21 is connected with second connecting rod 22.As shown in Figure 2 and Figure 4, first connecting rod 21 comprises that two have the journal stirrup 211 arranging in opposite directions, and journal stirrup 211 is provided with the first perforation 212; One end that second connecting rod 22 is not connected with handle 10 is as shown in Figures 2 and 3 provided with the second perforation 221, and first connecting rod 21 passes through through the bolt 23 of the first perforation 212 and the second perforation 221 hinged with second connecting rod 22.Meanwhile, because first connecting rod 21 adopts articulated manner to be connected with second connecting rod 22, thereby first connecting rod 21 and the relative angle of second connecting rod 22 can be regulated, make this bending connecting rod 20 be more applicable for actual job.

Preferably, the first connecting rod 21 of bending connecting rod 20 can pass through arc-shaped transition with second connecting rod 22, and first connecting rod 21 is one-body molded with second connecting rod 22.Obviously, bending connecting rod 20 also can be other bending shape.
