Abstract
Disclosed is a pair of garden shears. The pair of garden shears comprises an upper cutter body (1) and a lower cutter body (2). A through hole (3) is formed in a connection position of the upper cutter body (1) and the lower cutter body (2). A bolt (31) penetrates through the through hole (3) and is connected with a nut (32), and the upper cutter body (1) and the lower body (2) are enabled to be movably connected together. An adaptive self-lubricating bearing (4) is arranged between the inner wall of the through hole (3) and the bolt (31). Compared with the prior art, due to the fact that adaptive self-lubricating bearing is arranged between the inner wall of the through hole and the bolt, wherein the through hole is formed in the connection position of the upper cutter body and the lower cutter body, the pair of the garden gears is labor-saving and flexible when in use, and meanwhile the purpose of effectively prolonging the service life of the pair of the garden shears is achieved. Due to the fact that sawteeth are arranged on the back portion of a knife edge of a cutting blade portion, branches can be sawed off and clipped, and then the sawteeth bring convenience for pruning the branches, and the pair of garden shears is enabled to be wide in application range and practical.
Description
Technical field
The utility model relates to a kind of scissors for trimming leaf, especially refers to a kind of garden shears.
Background technology
Existing a kind of patent No. is that 200920176633.2 Chinese utility model patents that are called " garden shears " disclose a kind of garden shears, include left cutter hub and right cutter hub, be respectively arranged with the edge of a knife and handle at left cutter hub and right cutter hub, on left cutter hub and right cutter hub, also be respectively arranged with the hole, the employing screw passes the hole on left cutter hub and the right cutter hub, by cap nut locking screw, left cutter hub and right cutter hub are movably connected.During dismounting two parts cutter hub, first cap nut is screwed off from screw, screw is taken out in the hole of two parts cutter hub again, two parts cutter hub has just separated.Main Function is to be user-friendly to garden shears.But its shortcoming is: it is to be connected by simple turning cylinder that left cutter hub is flexibly connected with right cutter hub, so the intelligence alive of rotating is poor, to overcome turning cylinder frictional force during use and increase shearing force, cause easily hand-held fatigue, so the structure of this utility model be still waiting further improvement.
Summary of the invention
Technical problem to be solved in the utility model be provide for above-mentioned prior art present situation a kind of design ingenious, use laborsaving and flexibly a kind of garden shears are rotated in rotating shaft.
The utility model solves the problems of the technologies described above the technical scheme that adopts: these garden shears, include the upper knife body of blade and handle one and the lower knife body of blade part and handgrip one, the junction of described upper knife body and lower knife body is provided with through hole, be equipped with bolt in the described through hole and be connected with nut, upper knife body and lower knife body are movably connected, it is characterized in that: be provided with suitable self-lubricating bearing between described through-hole wall and the bolt.
As improvement, described self-lubricating bearing concrete structure be comprise and torus that through-hole wall is isometric and be arranged on bolt head and cutter hub between annulus.
As improvement, described torus and annulus are the disposable overall structure that is made.
As improvement, described self-lubricating bearing is copper base composite bearing.
As improvement, the edge of a knife back of described blade part is provided with sawtooth.
As improvement, described sawtooth links together by welding and the edge of a knife back of blade part, perhaps, described sawtooth and edge of a knife back be disposable casting form overall structure.
Compared with prior art, the utility model is by being provided with suitable self-lubricating bearing between the through-hole wall of upper knife body and lower knife body junction and bolt, not only the self-lubricating bearing wearability is good, and its coefficient of friction is less, thereby make garden shears more laborsaving in use, dexterousr, also reach simultaneously this garden shears of effective prolongation purpose in service life, and be provided with sawtooth by the edge of a knife back at blade part, can carry out sawed-off pruning to the tree skill, then further for the finishing branch brings convenience, make these garden shears range of application wider, more practical.

Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
The garden shears of the utility model embodiment as shown in Figure 1 to Figure 3, comprise blade 11 and the upper knife body 1 of handle 12 one and the lower knife body 2 of blade part 21 and handgrip 22 one, all be equipped with suitable grip on described handle 12 and the handgrip 22, the edge of a knife back of described blade part 21 is provided with sawtooth 5 by welding or with the mode that pour into a mould at edge of a knife back, described blade 11 all is provided with corresponding through hole 3 with blade part 21 afterbodys, be equipped with bolt 31 in the through hole 3 and by nut 32 upper knife body 1 and lower knife body 2 be movably connected at the other end, and be provided with suitable self-lubricating bearing 4 between described through hole 3 inwalls and bolt 31, described self-lubricating bearing 4 is copper base composite bearing.Described copper base composite bearing is a kind of known structure, no longer carefully states at this.
A kind of self-lubricating bearing 4 of the utility model embodiment as shown in Figure 5, its concrete structure for and isometric torus and the annulus that is arranged between bolt 31 heads and the cutter hub of through hole 3 inwalls.
The another kind of self-lubricating bearing 4 of the utility model embodiment as shown in Figure 4, its concrete structure is the torus isometric with through hole 3 inwalls, and torus with bolt 31 heads one end place to around extend for the suitable annulus of bolt 31, namely described torus and annulus are the disposable overall structure that is made.
Garden shears of the present utility model reduce the relative friction of cutter hub and bolt by between the through-hole wall of upper knife body and lower knife body junction and bolt self-lubricating bearing being set, and have increased the flexibility of these garden shears.Simultaneously at the edge of a knife back of blade part sawtooth is set, has increased the effect of sawed-off branch, improved the practicality of these garden shears.
