Description

The line walking knife saw

Technical field

The utility model relates to a kind of knife saw of the usefulness of removing obstacles, the line walking knife saw that uses when specifically being meant a kind of power circuit line walking.

Background technology

Along with the continuous development of China's modernization construction, power grid construction is constantly development thereupon also, yet in actual line walking work; Be near the branch the cleaning electric wire, need to use different line walking knife saws, realize multi-mode operations such as colluding, saw, shovel, draw, cut; All can not extend and shorten but the bar of traditional line walking knife saw is long, and the knife saw head is to be fixed on the knife saw bar with rivet or other modes, can easily not change; In order to satisfy the needs of cleaning job site, must be with the line walking knife saw of long, the different knife saw head of different bars, like this; Not only carry inconvenience, increased burden, and caused the waste of resource.

The utility model content

The utility model technical issues that need to address provide a kind of long extending and shortening of bar of knife saw, and removable the removing obstacles of knife saw head used the line walking knife saw.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

A kind of line walking knife saw comprises knife saw head and knife saw bar, and said knife saw bar two ends are provided with screw thread; The knife saw head is through being threaded in an end of knife saw bar, and the knife saw bar other end is provided with the joint that connects another knife saw bar.

Said knife saw head is a reaping hook, and the inboard of camber bent portions is a blade.

Said knife saw head is the saw cutter, and the front end of saw cutter is recessed meniscate blade, and a side of saw cutter is a sawtooth, and another side is a blade.

Because the technological progress of having adopted technique scheme, the utility model to obtain is:

Be threaded with joint between the knife saw bar of the utility model, can connect many knife saw bars as required, realized the elongation and the shortening of bar, greatly satisfied the needs of job site the knife saw of different length; With being threaded, can be replaced by difform knife saw head easily between knife saw head and the knife saw bar, accomplish to utilize a bar to realize multi-mode operations such as colluding, saw, shovel, draw, cut.

Description of drawings

Fig. 1 is the structural representation of knife saw head for the line walking knife saw of saw shovel;

Fig. 2 is that the knife saw head is the structural representation of the line walking knife saw that colludes of reaping hook;

Wherein, 1, the knife saw head, 2, the knife saw bar, 3, joint.

The specific embodiment

Below in conjunction with description of drawings the utility model is explained further details:

As depicted in figs. 1 and 2; This line walking knife saw comprises knife saw head 1, knife saw bar 2 and joint 3; Knife saw head 1 is connected with an end of knife saw bar 2 through screw thread, and the other end of knife saw bar 2 and joint 3 are through being threaded, and joint 3 two ends are provided with the screw thread that is connected with knife saw bar 2.

In use, according to the construction needs, when needing extension bar long; Can below joint 3, connect one or many knife saw bars 2 again, when needing to shorten the bar length of knife saw, only need disassemble unwanted knife saw bar 2 can realize; In addition, knife saw head 1 is through being threaded, changing conveniently with knife saw bar 2; Can change the head of knife saw according to the construction needs.

As shown in Figure 1, wherein a kind of knife saw head is the saw cutter, and the front end of saw cutter is recessed meniscate blade; One side of saw cutter is a sawtooth, and another side is a blade, and recessed meniscate blade can be used as scoop and uses; Side sawtooth sawing thing, the blade of another side can be realized the function of cutting.
