Abstract
The utility model discloses a hand saw, which comprises a handle and a saw plate connected with the handle. A plurality of saw teeth are arranged on the saw plate, the saw teeth are divided into left teeth, right teeth and middle teeth, the distribution of the left teeth, the right teeth and the middle teeth on the saw teeth is a cyclic permutation of a left tooth-a right tooth-a middle tooth-a left tooth-a right tooth-a middle tooth, or a cyclic permutation of a right tooth-a left tooth-a middle tooth-a right tooth-a left tooth-a middle tooth. The utility model has reasonable saw tooth structural design, the operation is time saving and labor saving, the slag tap is smooth, the tapped slag is tiny, the utility model enhances the working efficiency, and saves the labor force, and the utility model can be reused, thereby saving expenditures for consumers.
Description
Technical field
The utility model relates to the handsaw technical field, particularly a kind of time saving and energy saving handsaw.
Background technology
Handsaw is the instrument that the carpenter uses always, and its structure is also varied.The arrangement mode of the handsaw sawtooth in past is right tooth, middle tooth, left tooth, middle tooth cycle arrangement, and the middle tooth of this sawtooth is too many, and operating efficiency is not high, and the kerf out-of-flatness.The handsaw of selling on the existing market, its sawtooth adopts right tooth, left tooth, right tooth, left tooth cycle arrangement, this sawtooth does not have center tooth, its shortcoming is to slag tap unfavorablely, and the wooden slag that is gone out is bigger, wastes time and energy, and it is to put the first edge on a knife or a pair of scissors with mill section machinery that this sawtooth puts the first edge on a knife or a pair of scissors, handsaw is with after blunt, and most consumers does not have the machinery of putting the first edge on a knife or a pair of scissors, and very difficult reparation is reused.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of time saving and energy saving, reusable, the handsaw of high efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of handsaw, comprise handle 2 and the saw plate 1 that links to each other with handle 2, saw plate 1 is provided with a plurality of sawtooth 3, sawtooth 3 is divided into left tooth, right tooth and center tooth, it is characterized in that: the left tooth on the described sawtooth 3, right tooth and center tooth be distributed as left tooth-right tooth-center tooth-left tooth-right tooth-center tooth cycle arrangement.
For achieving the above object, the utility model also can adopt another kind of technical scheme: a kind of handsaw, comprise handle 2 and the saw plate 1 that links to each other with handle 2, saw plate 1 is provided with a plurality of sawtooth 3, sawtooth 3 is divided into left tooth, right tooth and center tooth, it is characterized in that: the left tooth on the described sawtooth 3, right tooth and center tooth be distributed as right tooth-left tooth-center tooth-right tooth-left tooth-center tooth cycle arrangement.
The utility model compared with prior art has the following advantages: the utility model broached-tooth design is reasonable in design, and is time saving and energy saving during use, the profit of slagging tap, and it is tiny that institute goes out wooden slag, improved operating efficiency, saved the labour, reusable, for the consumer has saved spending.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I enlarged drawing of Fig. 1.
Fig. 3 is first kind of arrangement mode of sawtooth on the utility model saw plate.
Fig. 4 is the another kind of arrangement mode of sawtooth on the utility model saw plate.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises handle 2 and the saw plate 1 that links to each other with handle 2, saw plate 1 is provided with a plurality of sawtooth 3, sawtooth 3 is divided into left tooth, right tooth and center tooth, the left tooth on the described sawtooth 3, right tooth and center tooth be distributed as left tooth-right tooth-center tooth-left tooth-right tooth-center tooth cycle arrangement.
Be illustrated in figure 4 as the another kind of arrangement mode of sawtooth on the utility model saw plate, the left tooth on the described sawtooth 3, right tooth and center tooth be distributed as right tooth-left tooth-center tooth-right tooth-left tooth-center tooth cycle arrangement.
In order to make the utility model obtain best effect, the number of the left tooth on the described sawtooth 3, right tooth and center tooth equates.
Sawtooth 3 as shown in Figure 3 and Figure 4 also is applicable to the power saws and the handsaw of other different shape, as long as adopt the rack saw of this kind structure, all in protection domain of the present utility model.
If first the practical tooth near handle 2 positions on the sawtooth 3 is a center tooth; then the left tooth on the sawtooth 3, right tooth and center tooth is distributed as center tooth-right tooth-left tooth-center tooth-right tooth-left tooth cycle arrangement or center tooth-left tooth-right tooth-center tooth-left tooth-right tooth cycle arrangement; the groove of these two kinds of sawtooth arrangement modes is identical with the sawtooth groove of the technical scheme of the utility model protection, also in protection domain of the present utility model.
