Electric scissors blade opening control structure

The present invention relates to an electric scissors blade opening control structure, and more particularly to a cutting machine that allows the opening of the blade to be switched according to the diameter of the branch to perform an efficient cutting operation.

The general pruning shears are mainly applied to the trimming work of gardening flowers and trees. Among them, the manual pruning shears will design a spring between the two grips, so that when the user performs the cutting work, the spring force of the spring is directly overcome. The two grips are relatively close together for the cutting operation, but the operation of the pruning shears described above is quite laborious when actually cutting a large diameter branch.

For the large-diameter branching work described above, as shown in the pruning shear structure disclosed in U.S. Patent No. 4,094,064, it can be constructed by a lever-saving structure, in the process of repeatedly applying force, loosening, and re-energizing. Cut the branches to achieve the effect of segmentation and labor-saving shearing. However, for the pruning operation of the twigs, the original force can be cut once, but because of the above-mentioned lever labor-saving structure design, it is necessary to force the user to adopt the operation mode of the sectional force application. Thus, as shown in U.S. Patent Publication Nos. US20120047750, US20130031786, and European Patent No. 2,637,493, each of the pruning shears can be provided with two operating modes through a movable element to achieve one shear or split shear for different diameter branches. The effect of breaking.

However, the above-mentioned various pruning shears must be cut by the user's hand. Power operation can be completed. Whether it is cutting small diameter branches for a long time or cutting large diameter branches for a short time, there will be problems that cause the user's hands to be tired or labor injury, and in the way of manual operation, The efficiency is not enough.

In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development improvements, and this creation has not been produced.

One of the purposes of the present invention is to provide an electric scissors blade opening control structure that drives an opening of a group of blades to be opened or closed by an electric driving component, and the cutting operation of the conventional pruning shear must be operated by the user's hand strength. However, it is easy to cause hand fatigue, labor injury, and insufficient efficiency, and can provide a more comfortable operation mode for the user and effectively improve work efficiency.

One object of the present invention is to provide a first sensing unit on a linking member for allowing the first sensing unit and the plurality of second sensing units to be correspondingly sensed when the linking member moves axially relative to the transmitting member. The electric scissors blade opening control structure that controls the opening size of a set of blades can solve the problem of insufficient efficiency of the cutting operation of the conventional pruning shears, and can make the opening of the blade switch according to the diameter of the branch to make the efficiency Tailoring work.

For the purpose of the above creation, the electric scissors blade opening control structure of the present invention is positioned in the casing for controlling the opening or closing of the pruning opening formed by the first blade and the second blade. The main technical feature is that the control structure includes an electric drive component, a linkage, a plurality of second sensing units, and a control unit. Wherein, one end of the electric drive component has a transmission member; the linkage member is coupled to the transmission member in a relatively movable manner, and the linkage member is coupled to the first blade for interlocking to swing the first blade, and the first induction is provided on the linkage member Unit; The plurality of second sensing units are disposed corresponding to the first sensing unit, and the plurality of second sensing units are connected to the control unit, and the control unit is electrically connected to the power driving assembly.

In practice, the transmission member is a screw having an internal thread that is screwed to the screw.

In the implementation, the linking member includes a moving portion and a linking portion. The moving portion is coupled to the transmission member in a relatively movable manner. One end of the linking portion is pivotally connected to the moving portion, and the other end of the linking portion is pivotally connected to the first blade. The linkage causes the first blade to oscillate.

In implementation, the first sensing unit is a magnet and the second sensing unit is a Hall sensor.

In order to facilitate a deeper understanding of this creation, it is detailed later:

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a preferred embodiment of the present invention.

Figure 2 is a cross-sectional view of a preferred embodiment of the present invention.

Figures 3 and 4 are diagrams showing the state of use of the preferred embodiment of the present invention.

Referring to Figures 1 and 2, which is a preferred embodiment of the present invention, the electric scissors blade opening control structure 1 is positioned in an elongated housing 2 having a front end and a rear end. The rear end of the housing 2 has a power input unit 21 for inputting direct current; a front end of the housing 2 protrudes outwardly from a first blade 22 and a second blade 23, and the first blade 22 and the second blade 23 are intersected. The pivoting and the second blade 23 are in a fixed state. When the user presses the switch 24, the first blade 22 can be swung relative to the second blade 23, so that the pruning of the first blade 22 and the second blade 23 is formed. The port is opened or closed.
