Description

Novel scissors saw

Technical Field

The utility model relates to an instrument, especially a scissors saw of usefulness is pruned to branch are used in gardens, fruit tree operation.

Background

In the operation process of gardens, fruit trees, traditional branch pruning generally is that secateurs and handsaw cooperate the use. The small branches are cut off by the pruning shears, and the big branches are sawed by the hand saw. When pruning the branches of different diameters, the pruning scissors and the handsaw need to be changed back and forth for use, lead to the operator often to carry the pruning scissors and the handsaw simultaneously on one's body, and it is extremely inconvenient not only to make a round trip to change during the use, still can increase workman's the amount of labour, influences work efficiency. The inventor's Chinese patent publication No. 208370362 ' a crescent-shaped scissors saw ' discloses a tool with functions of clamping scissors and sawing scissors, which effectively solves the problems. However, the saw tooth head of the scissors saw is integrated with the handle of the scissors, and when the saw teeth and the like on the saw tooth head are damaged and need to be replaced, the whole scissors saw needs to be discarded, so that waste is caused. And only one saw tooth head is arranged on one scissors saw, and the saw tooth head with other sizes or shapes can not be replaced according to the requirements, so that the application range is small.

Disclosure of Invention

The utility model aims to solve the technical problem that a novel scissors saw is provided to realize the removable of sawtooth head, reduce extravagantly, enlarge the range of application.

The utility model discloses a realize like this: the utility model provides a novel scissors saw, it has left hand handle and right hand handle, two handle upper portions are in the same place through the hinge is articulated, the left hand handle upper end is first connecting portion, first removable sawtooth head is installed through a plurality of first bolts to the upper end of first connecting portion, there are a plurality of first sawtooth in the inboard of first removable sawtooth head, right hand handle upper end is the second connecting portion, the removable sawtooth head of second is installed through a plurality of second bolts to the upper end of second connecting portion, there are a plurality of second sawtooth in the inboard of the removable sawtooth head of second.

The inner side of the second connecting part is provided with a crescent blade.

The lower end of one of the left handle and the right handle is hinged with a locking rod, and the upper side of the locking rod is provided with a plurality of locking teeth.

And a torsion spring is arranged between the left handle and the right handle.

The first replaceable sawtooth head and the second replaceable sawtooth head are in one of a crescent shape and a straight plate shape.

The scissors saw with the structure is reasonable in structure, and after sawteeth on the saw teeth are damaged, the saw teeth can be conveniently taken down to be replaced, so that waste is effectively reduced, the saw teeth with other sizes or shapes can be replaced, and the application range is expanded. And the operation is labor-saving and the use effect is good.

Detailed Description

The following embodiment is provided in conjunction with the accompanying drawings to further illustrate the specific structure of the present invention.

As shown in the attached drawing, the utility model relates to a novel scissors saw, it has left handle 7 and right hand handle 13, two handle upper portions are together articulated through hinge 6, the left handle upper end is first connecting portion 14, first removable sawtooth head 16 is installed through a plurality of first bolts 15 to the upper end of first connecting portion, the inboard of first removable sawtooth head has a plurality of first sawtooth 17, right hand handle upper end is second connecting portion 4, removable sawtooth head 2 of second is installed through a plurality of second bolts 3 to the upper end of second connecting portion, the inboard of the removable sawtooth head of second has a plurality of second sawtooth 1.

At each bolt mounting location, each replaceable serration head and each connection portion has internal threads. When the sawtooth head is damaged, the first bolt or the second bolt can be detached through the tool, and a new replaceable sawtooth head is replaced. The sawtooth head can be replaced by a sawtooth head with different sizes or shapes according to the requirement. Obviously, the outer end of each bolt is positioned at the outer side of each replaceable sawtooth head, and the inner end of each bolt is parallel to or lower than the inner side surface of the mounting part of each connecting part so as to prevent the bolts on the two connecting parts from colliding with each other when in use.

The inner side of the second connecting part 4 is provided with a crescent blade 5. The back of the first connecting part is provided with a bevel blade or a crescent blade. When in use, the blade can be used for cutting thinner branches.

The lower end of one of the left handle 7 and the right handle 13 is hinged with a locking rod 12, and the upper side of the locking rod is provided with a plurality of locking teeth 11. When the pair of scissors is used, after the branches are clamped by the two sawtooth heads, the locking teeth can be locked at the lower end of the other handle to lock the two handles, the hands of an operator do not need to apply clamping force, and the branches can be sawed and cut only by rotating the scissors saw, so that labor is saved. The locking lever is hinged to the handle by a shaft 10. The spring leaf 9 can be arranged on the inner side of the handle close to the hinged part, when the locking rod is folded outwards, the head part of the locking rod compresses the spring leaf, and after the locking teeth of the locking rod are separated from the other handle, the locking rod can be folded inwards under the action of the elasticity of the spring leaf, so that the locking rod is conveniently hidden on the inner side of the handle, and the space occupation of the locking rod is reduced. The elastic force also plays a role in preventing the locking tooth from being separated from the other handle.

A torsion spring 8 is arranged between the left handle 7 and the right handle 13.

The first replaceable sawtooth head 16 and the second replaceable sawtooth head 2 are in one of a crescent shape and a straight plate shape. The first and second replaceable sawtooth heads in fig. 1 are crescent-shaped sawtooth heads. The first and second replaceable saw tooth heads of fig. 2 are straight saw tooth heads. Obviously, the size and shape of the two replaceable sawtooth heads on a scissors saw should be the same.

The saw teeth can be straight teeth, helical teeth or a saw tooth shape disclosed in 'a crescent type scissors saw' with a Chinese patent publication No. 208370362.

The mounting structure of the replaceable saw bit shown in fig. 3 is a manner that the connecting portion of the replaceable saw bit is overlapped with the connecting portion of the connecting portion. Figure 4 shows the replaceable saw bit attachment portion hidden within the attachment portion. FIG. 5 shows the replaceable tip connection portion being bent and then connected to the connection portion. Each mounting structure can be selected as required.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
