Abstract
The invention relates to a multifunctional crowbar comprising a crowbar body and a hook. The hook comprises a vertical part and a bent part. The vertical part of the hook is provided with a thread. The crowbar body is provided with ducts, the adjacent ducts are equally spaced, the vertical part of the hook is in clearance fit with the ducts, and the vertical part of the hook is perpendicularly connected with the crowbar body through a nut. The multifunctional crowbar is simple in structure and reasonable in design; the hook is added to the multifunctional crowbar, so that workers can hook and pull a spring through the crowbar conveniently.
Description
Technical field
The present invention relates to a kind of Multifunctional crow bar.
Background technology
On-the-spot at construction of transformer substation at present, in the time of need to installing the big spring of spring device switch maintenance spring or spring device, spring needs stressed stretching.In prior art; staff adopts the tip of crowbar that spring is prized and drawn more; but common crowbar is subject to the impact in landform and geographic position larger; usually can not find suitable fulcrum; can only jointly cooperate by a plurality of crowbars; use procedure is time-consuming, and undue force also easily causes staff injured.
Summary of the invention
the object of this invention is to provide a kind of Multifunctional crow bar.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Multifunctional crow bar, comprise crowbar body, described crowbar also comprises hook, hook comprises vertical portion and curve, the vertical portion of hook is provided with screw thread, and crowbar body is provided with hole slot, and adjacent holes separation is identical, vertical portion and the hole slot free-running fit of hook, and be connected with crowbar body is vertical by nut.
During work, determine the distance of hook and crowbar body end, by the hole slot free-running fit of relevant position on the vertical end of hook and crowbar body, then by nut, be threaded with the vertical portion of hook, prevent that hook and crowbar body from departing from, meanwhile, vertical portion connection location that can be by nut and hook different, regulate the distance of curve and the crowbar body of hook.
Preferably, the curve tip of described hook is provided with luminescent powder coating.
Luminescent powder coating can play certain illuminating effect in the situation that light is not good, facilitates staff to get spring by most advanced and sophisticated hook of curve of hook.
Compared with prior art, tool has the following advantages in the present invention: simple in structure, reasonable in design, on crowbar, add hook, and facilitate staff by crowbar, the hook of spring is got and stretched.
Accompanying drawing explanation
fig. 1 is structure front elevational schematic of the present invention;
Fig. 2 is structure schematic top plan view of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1-2, Multifunctional crow bar, comprise crowbar body 1, described crowbar also comprises hook, and hook comprises vertical portion 3 and curve 4, the vertical portion 3 of hook is provided with screw thread, crowbar body 1 is provided with hole slot 2, and adjacent hole slot 2 spacing are identical, vertical portion 3 and hole slot 2 free-running fits of hook, and be connected with crowbar body 1 is vertical by nut 5, the most advanced and sophisticated place of curve 4 of hook is provided with luminescent powder coating.
During work, determine the distance of hook and crowbar body 1 end, by hole slot 2 free-running fits of relevant position on the vertical end of hook 3 and crowbar body 1, then by nut 5, be threaded with the vertical portion 3 of hook, prevent that hook and crowbar body 1 from departing from, meanwhile, can be by nut 5 vertical portion 3 connection locations different with hook, regulate the curve 4 of hook and the distance of crowbar body 1.Luminescent powder coating can play certain illuminating effect in the situation that light is not good, facilitates staff to get spring by most advanced and sophisticated hook of curve 4 of hook.
