Description

Gardening shears adjust the opening structure (1)

This creation is about a gardening shear structure, especially an easy-to-operate gardening shear adjustment opening structure (1).

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 (1) in view of the above-mentioned shortcomings existing in the prior art.

The cutting edge protrudes from the periphery of the shaft hole and protrudes from the axial direction with a limiting rod. The cutting edge is provided with a perforation, and the limiting rod is inserted into the perforation to form a fixed portion. A cutting drill defines a shaft groove to form a pivotal connection with the cutting edge, and the shaft hole of the cutting edge and the shaft groove of the cutting drill are secured by a lock. Forming a pivotal connection with a bolt to lock, and the shaft groove and the locking body are formed with at least one flat portion, and a first arcuate groove is defined in the outer periphery of the axial groove, and a limiting rod is provided by the first curved groove. The second cutting handle is disposed on the extending end of the cutting hole, and the second handle is recessed with a first hole and a second hole near the axial groove. The toggle button, the cutting edge and the cutting hole The utility model is coaxially pivoted, and the dial button is concavely provided with a second arcuate groove, the second arcuate groove provides a positioning rod, and the toggle button has a push handle extending at one end, and the push handle is convex There is a positioning bump.

In another embodiment of the present invention, a cutting edge is provided with a first handle at an extending end, and a shaft hole is defined between the cutting edge and the first handle, and the cutting edge defines a second hole around the shaft hole. An arc groove, a shear drill has a shaft groove and is formed with a cutting edge The shaft hole of the cutting edge and the shaft groove of the cutting edge are pivoted by a bolt to lock with a bolt, and the first arc groove is formed by the outer circumference of the shaft groove matching the second arc groove. In addition, the cutting end is provided with a second grip on the extending end, the dialing button and the cutting edge are coaxially pivotally connected with the cutting and drilling system, and the toggle button is convexly provided with a limiting rod, the limiting rod and the toggle button can be For integral molding, the limiting rod is simultaneously disposed in the first arc groove and the second arc groove.

The main purpose of the creation is that the cutting edge, the cutting drill and the toggle button are provided with a limit rod, a first curved groove and a second curved groove, and the first curved groove and the second are adjusted by the toggle button. The overlapping area of the arcuate grooves thereby forming a displacement limit on the limit rod, thereby forming an adjustment effect of the size of the opening of the cutting edge and the cutting, so as to improve the practicability.

The secondary purpose of the creation is that the cutting edge, the cutting drill and the toggle button are provided with a limit rod, a first curved groove and a second curved groove, and the first curved groove is controlled by the toggle button. The overlapping area of the two curved grooves allows the user to operate with only one hand holding the cutting tool to improve the ease of operation.

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.
