Specific embodiment
Below in conjunction with attached drawing, to the utility model, above-mentioned and other technical characteristic and advantage carry out clearly and completely
Description, it is clear that described embodiment is only the section Example rather than whole embodiments of the utility model.
In one embodiment, it as shown in Figure 1, present embodiments providing a kind of building steel bar hook, including shank 2, sets
Bill 1 in the front end of shank 2, the handle 3 set on the rear end of shank 2.In use, user will hold on the handle 3, bill is used
1, which hooks iron wire, to be pullled.And it is pullled generally along the axial direction of handle 3.In the present embodiment, handle 3 is wrapped
The interior shaft core 31 and outer shaft 32 included is all changed, as shown in Figure 2.It is that interior shaft core 31 includes coaxially connected upper first
Shaft core 311 and lower shaft core 312, the outer diameter of upper shaft core 311 are less than the outer diameter of lower shaft core 312, and upper shaft core 311 connects shank 2, lower axle
Core 312 stretches into the bottom of outer shaft 32；Secondly outer shaft 32 includes the link position positioned at upper shaft core 311 and lower shaft core 312
Circular cylindrical chamber 321；In the present embodiment, also the inside of handle 3 is changed.Specifically, handle 3 further includes first
Spring 34 and second spring 35, the first spring 34 are located in chamber 321, and against the connection of upper shaft core 311 and lower shaft core 312
Position；Second spring 35 is located at the bottom of outer shaft 32, and against the end of lower shaft core 312.
In the present embodiment, the first spring 34 and second spring 35 can provide interior 31 axial buffer of shaft core, and by double
Spring structure can also provide positioning while providing buffering.Because the first spring 34 and second spring 35 are along handle 3
Length direction be arranged on the inside of handle 3, so when being pulled to iron wire, the first spring 34 and second spring 35 can
