Abstract

The utility model relates to an electric pruner, which belongs to the technical field of electric tools and is provided with a shears pair and a casing for holding a motor. An output shaft of the motor is in transmission connection with an eccentric wheel, the shears pair is composed of a fixed blade and a moving blade, the fixed blade is fixedly connected with the casing, the fixed blade and the moving blade form a relative reciprocation pair, an elliptical ring fitting the eccentric wheel is arranged on the inner surface of the moving blade, an observation window and adjusting slot are arranged on the fixed blade, the observation window corresponds to the eccentric wheel in mounting position, the adjusting slot is along the relative movement direction of the moving blade, and the moving blade is provided with an adjusting pin extending out of the adjusting slot. By means of the electric pruner, the problem that sleeving the electric wheel is difficult for the elliptical ring of the fixed blade, no change to the original structure is needed, no additional part is needed, manufacturing cost is low, and the electric pruner is convenient to implement.

Description

A kind of electric shrub and hedge trimmer

Technical field

The utility model relates to a kind of electric shear, and especially a kind of electric shrub and hedge trimmer belongs to the electric tool technical field.

Background technology

Electric shrub and hedge trimmer is the beta pruning machine again, is a kind of electric tool commonly used that is used to prune the greening shrub.The basic structure of existing shrub and hedge trimmer is: have the housing and the scissors pair of settling motor; The output shaft of said motor and eccentric wheel driving coupling; Said scissors pair is by the ledger-plate that is fixedly connected with housing and form the secondary knife section that does relatively reciprocating motion with it and constitute, and the inner surface of said knife section has the elliptical ring that matches with said eccentric wheel.During assembling, need elliptical ring be entangled eccentric wheel, move back and forth, realize the shearing that cooperatively interacts with ledger-plate thereby eccentric eccentric motion can drive moving knife through elliptical ring.

Because different cut operation needs different scissors secondary, so the replacing of scissors pair is comparatively frequent.And when changing the scissors pair, eccentric wheel is in position immediately, and the position of elliptical ring is invisible, and therefore will make elliptical ring entangle eccentric wheel needs debugging repeatedly.Installation trouble during for fear of cutting ring; Publication number is that the european patent application of EP1859919A1 and EP1762136A2 discloses a kind of structure and method of being convenient to tool changing; Eccentric wheel wherein has presses close to the secondary trend of scissors under spring action; Even do not make elliptical ring entangle eccentric wheel when therefore installing, in case motor rotation, eccentric wheel will get among the elliptical ring at the correct position of motion process automatically.

Yet said structure not only need be changed original design, and has increased part, thereby causes shrub and hedge trimmer complicated, has improved manufacturing cost.

The utility model content

The purpose of the utility model is: the shortcoming to above-mentioned prior art exists under the prerequisite that does not increase part, proposes the secondary replacing of a kind of scissors electric shrub and hedge trimmer easy for installation.

In order to reach above purpose; It is secondary that the electric shrub and hedge trimmer of the utility model has housing and the scissors of settling motor; The output shaft of said motor and eccentric wheel driving coupling; Said scissors pair is by the ledger-plate that is fixedly connected with housing and form the secondary knife section that does relatively reciprocating motion with it and constitute; The inner surface of said knife section has the elliptical ring that matches with said eccentric wheel, and its improvements are: have the observation window of corresponding eccentric wheel installation position and the regulating tank consistent with the knife section direction of relative movement on the said ledger-plate, have the adjusting pin that from said regulating tank, stretches out on the said knife section outwardly.

Like this, when changing the scissors pair, not only can see through observation window and see the residing position of eccentric wheel, and can regulate pin, change the position of knife section, thereby make elliptical ring entangle eccentric wheel through stirring.After adopting the utility model, not only solved the ledger-plate elliptical ring and be difficult to entangle eccentric problem, and need not to change original structure, do not increased part, manufacturing cost economy is convenient to implement.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment

Embodiment one

The structure that the electric shrub and hedge trimmer of present embodiment unloads after the lower scissors pair is as shown in Figure 1, and is identical with prior art, has the housing 1 of settling motor, extends handle 2 on the housing, the output shaft of motor and eccentric wheel 3 driving coupling.

The scissors pair is as shown in Figure 2, by the razor shape ledger-plate 4 that is fixedly connected through alignment pin 4-1 with housing 1, and forms the secondary knife section of relative oscillating traverse motion 5 through swivel pin 5-1 with it and constitutes.The inner surface of knife section 5 has the elliptical ring 5-2 that matches with eccentric wheel 3.

Have on the ledger-plate 4 corresponding eccentric wheel installation position about two circular arc observation window 4-2 and the circular arc regulating tank 4-3 consistent with the knife section direction of relative movement, have the adjusting pin 5-3 that from regulating tank, stretches out on the knife section 5 outwardly.

When installing or changing swing scissors pair; As shown in Figure 3; See the residing position of eccentric wheel owing to can see through arc observation window 4-2; Therefore can regulate the corner that pin 5-3 changes knife section 5 through stirring, elliptical ring is in entangle eccentric position, thereby avoid the not corresponding difficult installation that causes in ledger-plate elliptical ring and eccentric wheel position.Be not difficult to find out that present embodiment is only left observation window and regulating tank in the ledger-plate appropriate location, on knife section, settle and regulate pin; Need not to change original structure, do not increase part, so technology is simple; Under the situation that cost increases hardly, greatly facilitate the secondary replacing of scissors and install.

Embodiment two

The structure that the electric shrub and hedge trimmer of present embodiment unloads after the lower scissors pair is also as shown in Figure 1, has the housing 1 of settling motor, extends handle 2 on the housing, the output shaft of motor and eccentric wheel 3 driving coupling.

The scissors pair is as shown in Figure 4, and by the spine shape ledger-plate 4 that is fixedly connected through alignment pin control 4-1 with housing 1, and the guide groove 4-6 that extends along its length through the ledger-plate middle part with it forms the secondary knife section of relatively back and forth translational motion 5 and constitutes.The inner surface of knife section 5 has the elliptical ring 5-2 that matches with eccentric wheel 3.Have on the ledger-plate 4 corresponding eccentric wheel installation position about two straight line observation window 4-2 and the left and right sides straight line regulating tank consistent with the knife section direction of relative movement, about two straight line observation window 4-2 connect with left and right sides straight line regulating tank respectively.Has the left and right adjusting pin 5-3 that from the left and right adjusting groove, stretches out on the knife section 5 outwardly.

When installing or changing swing scissors pair; As shown in Figure 4; See the residing position of eccentric wheel owing to can see through arc straight line window 4-2; Therefore can regulate the front and back position that pin 5-3 changes knife section 5 through stirring, until making elliptical ring entangle eccentric wheel, thereby avoid the not corresponding difficult installation that causes in ledger-plate elliptical ring and eccentric wheel position.Its advantage is identical with embodiment one, does not give unnecessary details in addition.
