Description

A connecting rod rose shear

technical field

The utility model relates to a gardening hand tool, in particular to a connecting rod type rose shears for cutting off plant branches.

Background technique

Among the commonly used gardening hand tools, the scissors used to cut off the branches of plants (such as roses) generally include: a pair of scissors pivoted by a pivot through the middle part, and the two scissors correspond to The two ends are respectively formed as a blade portion and a grip portion, and a spring is respectively pressed against corresponding parts of the two scissors with its two ends. When in use, the user grasps the two handles to force the two blades to swing toward each other until their edges overlap to cut off the plant branches lying therebetween, and when the user releases the two handles, By the force of the spring, the two overlapping blades are separated. The two blades of the conventional gardening shears move relative to each other in a swinging manner, and the gap formed between the edges of the two blades is V-shaped. The branches between the two parts are prone to slide toward the V-shaped gap, so that the cutting action cannot be completed. Although the user can hold the branch with the other hand to prevent it from sliding, this action is not suitable for rose bushes. Use when cutting prickly rose stems, and using these garden shears requires a lot of force to cut through thicker branches.

As an improvement of the above-mentioned technical solution of the utility model, the side wall of the notch that cooperates with the blade during shearing is provided with a groove corresponding to the strip-shaped through hole.

As a further improvement of the above-mentioned technical solution of the utility model, a spring is installed between the two handles.

As a further improvement of the above-mentioned technical solution of the utility model, the body is provided with a bump, and the handle is provided with a protruding edge that matches the bump; Set in an inwardly concave arc shape.

Each of the above-mentioned handles is provided with a bar-shaped groove, and the ends of the two connecting rods in the four-bar linkage mechanism are respectively pivotally arranged in the bar-shaped groove.

The beneficial effects of the utility model are: the utility model can be used by the user to hook a branch conveniently with the gap, and in the process of cutting off the branch placed in the gap, the branch is stopped by the inner wall of the gap It cannot slide outwards to improve its cutting efficiency and ensure the safety of users, and the force applied to the two handles is transmitted to the blade through the four-bar linkage, so that the utility model Language has a more labor-saving feature.

Detailed ways

Referring to Fig. 1 and Fig. 2, a connecting rod type rose shears disclosed by the utility model includes a body 1, and one end of the body 1 has a notch 11, and the notch 11 can be used to place the cut branches horizontally. A strip-shaped through-hole 12 is provided in the body 1, and one end of the strip-shaped through-hole 12 communicates with the notch 11. Two handles 2 are hinged on both sides of the body 1 away from the notch 11. The handle 2 can be used as shown in the figure. The combined structure can also be used as an integrated structure.

The body 1 is provided with a protruding block 13, and the handle 2 is provided with a protruding end edge 21 that cooperates with the protruding block 13. Through the cooperation between the protruding end edge 21 on the handle 2 and the protruding block 13 on the body 1, it can prevent Overextension of handle 2.

When cutting, the side wall of the notch 11 and the side wall of the bottom edge matched with the blade are set in an inwardly recessed arc shape, so that when the user hooks a branch with the notch 11, the branch is subjected to the inwardly recessed arc. The stopper of the shaped side wall cannot slide outwards, thereby preventing the hooked branches from falling off.

A blade 3 is arranged in the strip-shaped through-hole 12 of the body 1, and the blade 3 can reciprocate between a first position and a second position in the strip-shaped through-hole 12 along a straight line. One end of the blade 3 is provided with a blade 31 , the blade 31 can extend into the notch 12, and the side wall of the notch 12 that cooperates with the blade 31 during shearing is provided with a groove 14 corresponding to the strip-shaped through hole 12, and the blade 31 can extend into the groove 14, In order to ensure that the blade can completely cut off the branches during cutting, and improve its cutting efficiency.

A spring 4 is installed between the two handles 2, and the spring 4 can reset the two handles 2 after a cutting action, and the blade 31 of the blade 3 can always be kept in the strip-shaped through hole through the reset of the spring 4. 12 to prevent the blade from scratching the user when the rose scissors are idle, and to ensure the safety of the user.

The rose scissors of the present utility model is provided with a four-bar linkage mechanism 5, wherein the middle parts of two linkages 51, 52 of the four linkage linkage 5 are hinged, and one end of the two linkages 51, 52 is respectively connected to predetermined positions of the two handles 2. Hinged, the other ends of the two connecting rods 51, 52 are respectively hinged with one end of the other two connecting rods 53, 54, and the other ends of the two connecting rods 53, 54 are hinged at the predetermined position of the blade 3, when the two handles 2 rotate around the body 1 At the same time, the two connecting rods hinged at their predetermined positions are driven to move, and the two connecting rods drive the other two connecting rods at the same time, thereby driving the blade to move back and forth between a first position and a second position in the strip-shaped through hole along a straight line. . In this way, the power applied to the two handles is transmitted to the blade portion through the four-bar linkage, so that the utility model has more labor-saving characteristics compared with the conventional garden scissors.

As shown in the figure, in order to facilitate the installation of the two connecting rods 51, 52 hinged on the handle 2, a strip groove 22 is provided on each handle 2, and the ends of the two connecting rods 51, 52 hinged with the handle 2 are respectively It is pivotally arranged in the bar-shaped groove 22 .
