Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 6, the utility model provides a laborsaving pruning scissors of lever, including mutual articulated the first in command spare 1 and the second in command spare 2 and articulate the blade 3 on the first in command spare 1, for convenient installation and dismantlement, the blade 3 passes through fastening screw and articulates with the first in command spare 1.

Referring to fig. 1, 3 and 4, the pruning shears further comprise a lever structure, the second handle part 2 is connected with the blade 3 through the lever structure, and the second handle part 2 drives the blade 3 to rotate through the lever structure to shear during shearing, so that the labor-saving effect is achieved. The lever structure includes extension 31 that sets up at the blade 3 rear end, and extension 31 and blade 3 be the integrated into one piece formula structure, and extension 31 extends the setting towards second handle spare 2, is provided with waist type groove 32 on the extension 31, and threaded connection has locating part 4 on the second handle spare 2, and waist type groove 32 is arranged in to locating part 4. For the delicate structure, the limiting part 4 is a fastening screw, and an inner hexagonal groove is formed in the fastening screw.

Referring to fig. 5 and 6, the second handle 2 is provided with a screw post 21, and the screw post 21 is disposed near the hinge point of the second handle 2, so that the thrust of the limiting member 4 is greater. The outside of spiro union post 21 is provided with first accommodation groove 22, and extension 31 stretches into in first accommodation groove 22, and locating part 4 and spiro union post 21 threaded connection. One end of the second handle part 2 is provided with a first hinge part 23, the outer side of the first hinge part 23 is provided with a second accommodating groove 24, the second accommodating groove 24 is communicated with the first accommodating groove 22, the first handle part 1 is provided with a second hinge part 11, and the second hinge part 11 is arranged in the second accommodating groove 24 and is hinged with the first hinge part 23. The blade 3 and the first hinge portion 23 are respectively located at two sides of the second hinge portion 11, and the second hinge portion 11 is hinged to the first hinge portion 23 through a fastening screw.

Referring to fig. 1 and 4, the front end of the blade 3 is provided with a blade 33, the front end of the first handle member 1 is provided with a blade holder 12 corresponding to the blade 33, and the blade holder 12 and the first handle member 1 are integrally formed. The distance from the cutting edge 33 to the hinge point of the blade 3 is less than the distance from the extension part 31 to the hinge point of the blade 3, so that the driving force arm is increased, and the labor-saving effect can be achieved.

Preferably, the tail ends of the first handle piece 1 and the second handle piece 2 are sleeved with rubber anti-skidding sleeves 5, so that the anti-skidding and anti-friction effects are achieved, and the use is more comfortable.
