Cutting device control device

The present invention relates to a control device for trimming flower and tree branches, which can perform control of progressively segmented cutting and closing, and can be used to fold the cutting edge of the cutting tool when not in use.

Generally, the branches of plants are thick and thin. For example, the stems are often thick and hard. The gardening shears for trimming the branches must have sufficient sharpness to allow the user to operate more effortlessly. Designed a clipper structure with a segmentable cutting mode, and a clipper structure that can control the cutting mode. For example, Taiwan Patent No.: M420981, a gardening shear that can switch the cutting mode, so that the gardening shear can be switched and changed specifically for the scissors. Cutting the cutting pattern of the branch, comprising a first handle and a second handle pivotally connected to each other to provide a user's grip; a blade unit is pivoted at the front end of the first handle, so that the blade unit The cutter bit at the front end of the first grip corresponds to a cut; a drive link is pivoted on the second handle, and one end of the drive link is movably disposed at a rear end of the blade unit for pushing the blade unit to perform cutting; And a switching element is disposed on the second handle in a linear movable structure, so that the switching element can advance straight against the blade unit, and can also retreat from the blade unit in a reverse straight line; and a safety fastener, the safety buckle The piece of activity is disposed on the second handle to hold the blade of the blade unit when the gardening shear is closed.

Among the above patent elements, the switching element is a control cutting mode, and the other safety fastener is a closed blade unit actuating piece, the switching element and the safety fastener are separate elements, and are separately disposed on the second handle. Wherein the switching element is displaced back and forth in a push-up level, the safety fastener being actuated in a pendulum manner.

Therefore, the user has to operate the two components in order to control the cutter mode or close the cutter, which makes the operation inconvenient, and this structure allows the manufacturer to increase the assembly labor cost and component cost in the combination.

The invention is applied to a garden trimming shearing tool, which is mainly developed to reduce Manufacturing cost, and providing a flexible and convenient design, through the design of the control device to replace the cutting mode change of the cutting tool, and the control device also has a lock function, providing a pair of handles for cutting operations.

The invention provides a control device for a cutting tool, comprising two first members and a second member. The first member extends at one end to form an anvil. The first member is pivotally connected to one end, wherein one end of the blade extends to form a blade. a portion having a hollowed-out window extending from one end to form a pin; and the first member and the second member are pivotally connected to each other by a relationship member to allow the blade to pass through the drill portion The first member and the second member are operated to perform a cutting action; the second member has a first combination portion which is formed by the first wall and the second wall to form an accommodation space, and the first wall and the second wall are both a first bump and a second bump provided with a positioning function, wherein the receiving space is provided with a control device, the control device is pivoted to the first wall and the second wall, and the component comprises a pivotal connection And extending from the pivoting portion to form a first grip portion and a second grip portion, wherein the first grip portion and the second grip portion are a platform, wherein the platform is provided With grooves; and, a support body, which is made of a metal material, has a joint portion extending from the joint portion to form a back portion, and a hook portion is formed from one end of the back portion, wherein the joint portion is shaped to fit the groove shape, and the horizontal surface of the back surface is horizontal with the platform The surface of the hook portion protrudes out of the platform; and the pivoting portion is disposed in the recessed portion, and the pivot hole of the pivoting portion corresponds to the pivot hole of the first wall and the second wall, thereby making the system The device is pivotally connected to the second member, and the first grip portion and the second grip portion are pushed to perform a pendulum operation on the first wall and the second wall.

Wherein, when the first grip portion and the second grip portion are pushed to the first bump, the pin of the blade will abut against the back of the support body, so that the cutter can perform a cutting mode for cutting once, and push the first When the grip portion and the second grip portion are to the second bump, so that the pin of the blade does not abut against the back of the support body, the clipper can perform a segmented cutting mode; Continuing, moving the first member and the second member relative to each other to close the blade and the anvil, and then pushing the first grip portion and the second grip portion to the first bump and The position between the second bumps causes the hook to hook the pin of the blade, and the control device functions to lock the blade to close the anvil.
