Abstract

The utility model relates to a tree trimming tool, in particular to a tree pruning saw. The tree pruning saw comprises a saw head and a saw handle, wherein, the saw head is a rectangular part, sawteeth are arranged at one side of the saw head, regulating holes are arranged at the connected parts of the saw head and the saw handle; the saw handle is composed of a weighted plate and a telescopic rod, one end of the weighted plate is connected with the saw head and the other end is connected with the telescopic rod. Because the regulating holes are arranged at the connected parts of the saw head and the weighted plate, the angles of the saw head and the saw handle can be regulated randomly; meanwhile, the weight of the saw head is added, thereby the requirement of the operator for the angle of flat operation is satisfied, the action point of the tree pruning saw is lifted to the upper part of the tree branch, the mutual action between the sawteeth and the branch is increased and the requirement of the operator for force is satisfied.

Description

The trees trim saw

Technical field:

The utility model relates to the tree trimming instrument, especially a kind of trees trim saw.

Background technology:

Trees are pruned in necessary for growth, remove unwanted branch, for thicker branch, generally all cut down, but when using handsaw or cutter, need utilize double ladder or climb tree very inconvenience during operation with handsaw or cutter, and because work high above the ground, power can't be applied on handsaw or the cutter, not only the operator is tired easily, and operating efficiency reduces greatly.

Summary of the invention:

The technical problems to be solved in the utility model is: provide a kind of grading operation, easy to loading and unloading, use light and handy trees trim saw.

The technical scheme that solves its technical problem employing is:

A kind of trees trim saw, comprise: saw head, saw handle, described saw head is that a segment length is square, its sawtooth is arranged on a side of saw head, the linkage section of itself and saw handle is provided with adjustment hole, described saw handle is made of weighted plate and expansion link, and this weighted plate one end is connected with the saw head, and its other end is connected with expansion link.

Compared with prior art, the beneficial effects of the utility model are:

By saw head and weighted plate linkage section adjustment hole is set, not only can regulate the angle of saw head and saw handle arbitrarily, and increased the counterweight forces of saw head, promptly adapt to the requirement of operating personnel's grading operation angle, again the application point of trees trim saw is brought up to the middle and upper part of branch, strengthen the interaction force of sawtooth and branch, satisfied operating personnel's strength requirement.

Description of drawings:

Fig. 1 is the utility model structural representation.

Among the figure: saw 1, sawtooth 2, adjustment hole 3, weighted plate 4, interior loop bar 5, outer loop bar 6.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples:

A kind of trees trim saw is referring to accompanying drawing 1, by saw 1, sawtooth 2, adjustment hole 3, weighted plate 4, interior loop bar 5, outer loop bar 6 constitutes, and described saw 1 is that a segment length is square, and its sawtooth 2 is arranged on a side of saw 1, the linkage section of itself and saw handle is provided with adjustment hole 3, described saw handle is made of weighted plate 4 and expansion link, and these weighted plate 4 one ends are connected with saw 1, and its other end is connected with expansion link.

4 main bodys of weighted plate described in the present embodiment are rectangle, and its saw 1 linkage section is provided with adjustment hole 3, and it is connected with saw 1 by adjusting nut, and weighted plate 4 has strengthened the counterweight forces of saw 1, and then makes sawtooth 2 and the increase of branch active force.

Expansion link described in the present embodiment is made of interior loop bar 5 and outer loop bar 6, and interior loop bar 5 and outer loop bar 6 sockets by regulating the length of expansion link, can increase operating personnel's use height and angle, make operation more laborsaving.

Using method of the present utility model is summarized as follows:

At first will reconcile nut turns on, to saw 1 screws out from weighted plate 4 limits, to saw 1 fixing after transferring to 120 ° with the angle of weighted plate 4 then by adjusting nut, then expansion link is pulled out to the position of adaptation, grasp expansion link, the sawtooth 2 of saw 1 is connected on the branch to be pruned, and the pulling expansion link moves saw 1 on branch, and then cuts off branch, when the saw branch, keep saw 1 level, the strength of weighted plate 4 can better act on and saw on 1 like this, reaches the purpose of light sawed-off branch as far as possible, after finishing using, turn on adjusting nut, will saw 1 rotation, abut in weighted plate 4 one sides.

Claims (3)

1. trees trim saw, comprise: saw head, saw handle, it is characterized in that, described saw head is that a segment length is square, its sawtooth is arranged on a side of saw head, and the linkage section of itself and saw handle is provided with adjustment hole, and described saw handle is made of weighted plate and expansion link, this weighted plate one end is connected with the saw head, and its other end is connected with expansion link.

2. trees trim saw according to claim 1 is characterized in that described weighted plate main body is rectangle, and its saw linkage section is provided with adjustment hole, and it is connected with the saw head by adjusting nut.

3. trees trim saw according to claim 1 is characterized in that described expansion link is made of interior loop bar and outer loop bar, interior loop bar and outer loop bar socket.
