Description

Holding gardening scissor gear

Technical field

The utility model is related to a kind of orchard shears, espespecially a kind of holding gardening scissor gear.

Background technology

Press, orchard shears known at present, has two opposite cutting edges, cutting edge rear, which is equiped with, holds handle, and middle section is equipped with more Perforation, which is to lock knot by a screw and passing through for a nut, and makes two cutting edge energy phase pivot groups position, and handle is held when forcing in When upper, it can be sheared using as axle center, making cutting edge produce the change opened and closed at perforation with the folding using two cutting edges.So, such as The upper conventional construction, merely with simple opening and pairing, produces the orchard shears of shearing strength in practical application, can not Branch is easily cut, this relatively can not be laborsaving, uses demanders upper and departing from consumers in general.

Therefore, market has a kind of labor-saving gardening scissors at present, such as the transmission of No. 382194 of TaiWan, China patent announcement number The orchard shears driven is taken turns, it includes a first assembly and one second component to be formed；The first assembly includes a handle of a knife and one There is one first work department, interlude and one first articulated section, the articulated section to be combined with the lever for lever, the handle of a knife, and One first driving section is equipped with the side of the interlude, which has several first teeth groove and the first double wedge；This second Component includes a handle of a knife, a rocking arm and a lever, which has one second work department, interlude and one second pivot joint Portion, is articulated with the interlude of in-between section and the first assembly, and second articulated section is then pivotally connected with the rocking arm, the rocking arm One end is combined with the lever, and another end is then equipped with one second driving section, which also has several second double wedges and the second tooth Groove；It is driven by the double wedge and teeth groove intermeshing of two driving section, force is smooth, laborsaving and can the person of prolonging the service life.

See above-mentioned conventional construction in detail to be not difficult to realize that it has remained a little shortcoming, main cause is as follows：The first assembly And second component double wedge and teeth groove between all form open state, not only easily by foreign matter invade and have stuck doubt, but also In actual shearing, the structure of first and second inter-module more seems thin, lacks structural strength, and then can be more hard because shearing Stiff wood bar and cause first and second work department have stagger can not close really shearing situation produce, structure shear is greatly reduced Efficiency, does not have practicality.
