Description

Gardening shears adjust the opening structure

This creation is about a gardening shear structure, especially an easy-to-operate garden shear to adjust the opening structure.

The current horticultural shear structure is the "horticultural shear structure" of the MMC175 approved by the Department of Health, which was approved on November 1, 1994. The application date is February 5, 1994. It can be analyzed from the scope of the patent application and the drawings that the top end of the pivot block is provided with a beveled surface that is inclined to the right, and the movable jaw is clamped with a screw hole at a position opposite to the chamfered surface. Positioned between the spring and the shaft member, and an adjusting bolt is arranged on the screw. The bottom end of the adjusting bolt can abut the pivoting surface of the pivot block to adjust the angular travel of the movable jaw and the grip, and can be adjusted at the same time. The angular travel of the movable knife and the fixed knife seat allows the cutting tool to adjust the size of the cutting opening. However, it is not difficult to find out that the above-mentioned conventional structure has some shortcomings, the main reasons are as follows:

(1) The adjusting bolt penetrates through the screw hole in a screw locking manner, and the end of the adjusting bolt abuts the top to cut the inclined surface. Although the function of adjusting the size of the cutting opening is provided, the cutting surface and the adjusting are generated through the shearing action. The collision of the bolts makes the adjusting bolts easy to loosen and exit, and the size of the shearing opening cannot be effectively adjusted, so that the utility is insufficient.

(2) The adjustment of the shearing opening is achieved by adjusting the screw of the adjusting bolt, so that the single hand holding the shearing tool cannot be operated, and the screwing adjustment of the adjusting bolt is required It is necessary to rotate a considerable number of turns to adjust to the desired position, so that there is a lack of operational convenience.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

The technical problem to be solved by the present invention is to provide a gardening shear adjustment opening structure in view of the above-mentioned shortcomings existing in the prior art.

A cutting edge is provided with a first handle at one end of the cutting edge, and a shaft hole is defined between the cutting edge and the first handle, and the cutting edge defines a long groove and a short groove communicating with each other at the periphery of the shaft hole. The cutting drill is provided with a shaft groove and is pivotally connected with the cutting edge, and a long groove and a short groove are formed on the outer periphery of the shaft groove, and the long and short grooves are arranged on the long and short grooves of the cutting edge, and the cutting is performed. A second grip is disposed on one end of the extending sleeve, and a second retaining ring is wound around the shaft groove, and a receiving gap is formed in the limiting ring with the long and short grooves, and the receiving notch is concave a pivot hole is provided, wherein the shaft hole of the cutting edge and the shaft groove of the shearing hole are pivotally connected by a bolt and a bolt, and the shaft groove and the locking body are formed with at least one plane portion, and The second handle is recessed with a first hole and a second hole near the limiting ring. A swinging member has an arc forming a stop at one end, and a limiting rod is vertically extended at the other end. a pivoting rod is protruded between the blocking portion and the limiting rod, and the swinging member is installed at the receiving gap and is pivoted The pivoting hole is formed in the pivot hole, and the limiting rod is disposed in the length of the cutting edge, the short groove and the length of the shearing drill, and the short groove, and the button is pivoted on the axis of the limiting ring end. At the slot, and The dial button protrudes from a lever, and a push handle extends at one end of the dial button, and the push handle protrudes with a positioning protrusion.

The main purpose of the creation is that the cutting edge is provided with a long groove and a short groove, and the cutting hole is provided with a long groove and a short groove, and the long and short groove pairs of the cutting hole are arranged on the long and short grooves of the cutting edge, and The two ends of the swinging member respectively extend with a blocking portion and a limiting rod. The swinging member can control the limiting rod to be accommodated in the long and short grooves or the long and short slots, thereby forming an opening of the cutting edge and the cutting hole. The effect of the size adjustment, so as to improve its practicality.

The secondary purpose of the creation is that the cutting edge is provided with a long groove and a short groove, and the cutting hole is provided with a long groove and a short groove, and the swinging member forms a limit by the limiting rod passing through the cutting edge and the cutting drill, and The lever of the toggle button forms a control for the swinging member, so that the user can operate with only one hand holding the clip to improve the operation convenience.

Other objects, advantages and novel features of the present invention will become more apparent from the detailed description and the accompanying drawings.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please follow the following [simplified description of the drawings] as follows: First, please refer to Figure 1, Figure 2 and Section 3. As shown in the figure, a gardening shear adjustment opening structure includes: a cutting edge (10), a shearing drill (20), a swinging member (30) and a toggle button (40), a cutting edge ( 10) a first handle (11) is sleeved at one end of the extension, and a shaft hole (12) is defined between the cutting edge (10) and the first handle (11), and the cutting edge (10) is on the shaft A long groove (13) and a short groove (14) are formed in the outer periphery of the hole (12), and a cutting drill (20) defines a shaft groove (21) to form a pivotal connection with the cutting edge (10), and The long groove (22) and the short groove (23) are connected to each other at the periphery of the shaft groove (21), and the long and short grooves (13) are provided by the long and short grooves (22) (23).
