Description

gardening shears

technical field

The utility model relates to a branch scissors for gardening, which mainly improves the folding structure of the blade when it is not in use. The sliding part can form a linear sliding movement through the interlocking relationship between the sliding part and the fastening group. Reduce its push resistance for a more effortless snap-fit action.

Background technique

There is a known gardening scissors structure, as shown in Figure 6, which is mainly composed of upper and lower handles 50, 60 pivotally connected, and a spring 51 is sandwiched between the upper and lower handles 50, 60, Push away upper and lower handle 50,60 thus, make the knife seat 52 of front end and blade 61 be open state under normal state, this upper handle 50 is provided with a push block 53 at the outer edge place of pivoting lower handle 60, And the shaft hole 531 of the push block 53 is sleeved with a torsion spring 54, and the end of the push block 53 is formed with a push surface 532, and a resisting end 533 and a stop end 534 are respectively formed on both sides. 60 cooperates with pushing block 53 and is provided with a fixing groove 62, when carrying out the retracting action of knife seat 52 and blade 61, be to hold and press its upper and lower handles 50,60 directly, make knife seat 52 and knife edge 61 form closed state, and then push the push block 53 by the push surface 532, so that the conflicting end 533 of the push block 53 is placed in the fixing groove 62 of the lower handle 60, and is pushed against the stop end 533 of the push block 53 by the torsion spring 54, That is, the closed state of the knife seat 52 and the knife edge 61 can be maintained, so that it has the function of folding.

Looking at the above-mentioned known structures in detail, it is not difficult to find that there are still some deficiencies, the main reasons are as follows:

(1), the upper handle 50 is pivotally connected with a push block 53, and the contact end 533 of the push block 53 pushes against the fixed groove 62 of the lower handle 60. The push block 53 is based on the shaft hole 531. The shaft center yaws, that is, the pushing surface 532 slides in an arc shape, which increases the pushing resistance of the pushing block 53 , and makes the fastening action more laborious.

(2), the shaft hole 531 of the push block 53 is provided with a torsion spring 54, one end of the torsion spring 54 is limited to the inner side of the upper handle 50, and the other end pushes against the stop end 534 of the push block 53, thus Push the push block 53 down the fixing groove 62 of the handle 60. If the push block 53 is too loose, the push block 53 will be pushed into the fixing groove of the lower handle 60 by the thrust of the torsion spring 54 under the condition of use. 62, which reduces the smoothness of use.

In view of this, the creator has been engaged in the manufacture, development and design of related products for many years. After detailed design and careful evaluation for the above-mentioned goals, he finally obtained a practical utility model.

A hook-shaped fastening groove is formed at the outer edge, and the fixed scissors of the handle are pivotally connected by the fixed hole and the movable hole, and the connection between the handle and the side of the fixed scissors forms an accommodating space. The accommodating space is upwardly formed with a retracted limiting part, and there is a chute spaced from the fixed scissors, and the accommodating space is downwardly formed with an arc-shaped dodging hole, and the fixed scissors is penetrated by a positioning hole at the position of the dodging hole. A fastening group includes a fastening piece, an elastic piece and a positioning bolt. One end of the fastening piece is provided with a shaft hole, the other end is formed with a fastening end, and a recess is formed between the two ends. The elastic piece is a torsion spring, and There are front stoppers and rear stoppers formed at both ends. The positioning bolt is provided with fastening parts and elastic parts, and is fixed at the positioning hole of the fixed scissors. A sliding part is formed into a push button shape and protrudes at the lower There is a conflict block, and the limit block is extended from the side of the conflict block, and a limit slot is formed between the limit block and the push button body, and the conflict block and the limit block of the slider are all slid in the handle. placed in space.

The handle is connected with the fixed scissors to form an accommodating space. The fastening parts of the fastening group are arranged in the accommodating space, and the shaft holes of the fastening parts are aligned with the positioning holes of the fixed scissors, and the elastic parts It is set on the outer end of the fastening part, and the front stop part is in contact with the lower end of the fastening part, and the back stop part is in contact with the handle, and then the positioning bolt is passed through the shaft hole of the elastic part and the fastening part, and the positioning The bolt is riveted to the positioning hole of the fixed scissors, and the sliding part is slidingly set by the limiting groove and the limiting part of the handle, that is, the limiting block is set in the accommodating space, and the conflicting block also avoids the fastening part The fastening end of the fastening block is accommodated in the accommodation space, and the end of the conflicting block is set on the concave part of the fastening part. It is combined with the fastening group and the handle of the sliding part, and then fixed by the fixed cutting blade. The hole forms a pivot connection with the movable hole of the pressure handle, and can form a shearing action with the pivot joint as the axis, and a spring can be sandwiched between the pressure handle and the handle, thereby expanding the movable shear blade And fixed cutting edge to form a normally open shape.

Efficacy compared to previous techniques:

(1) The sliding part is slid on the chute of the handle, and the concave part of the fastening part in the accommodating space is set on the top of the conflicting block. When the sliding part moves forward, the fastening part can be pushed to resist The fastening groove of the movable scissors can form a linear sliding movement of the sliding part due to the interlocking relationship between the sliding part and the fastening group, thereby reducing its pushing resistance, so as to achieve a more labor-saving fastening action.

(2) For the elastic part in the fastening group, the front stop part is in contact with the lower edge of the fastening part, and the rear stop part is in contact with the inner end of the handle, thereby pushing the fastening part toward the inner end of the accommodating space Compression can keep the fastening end of the fastening part and the fastening groove of the movable scissors in a normally open shape, so as to prevent the fastening end from sliding and snapping into the fastening groove by itself, and improve the smoothness of use.
