Description

Horticultural secateurs

The utility model relates to garden shears, refers to have the garden shears of the adjustable rotary-locking device of the sound especially.

At present the kind of scissors not descend the hundreds of kind, mostly is to design the various scissors that are suitable for cutting all kinds of different article according to its purposes, and must possesses to hold and take light and handy and operate characteristics easily; Therefore, just have such as the sharp scissors of length that is used in art designing or work use, the dressmaker that the dress ornament cutting is used, the beta pruning scissors of outdoor Ping Yuan, be applicable to the orchard shears of fruit tree, flowers etc. in addition, the prune picker can use it to prune skill cleverly, cooperates profit to cut the branch stalk is produced various only wonderful only Xiao Jingguan with cauline leaf.

Existing garden shears, its pivot joint mode as shown in Figure 1, mainly be respectively to be provided with circular hole A1 and the slotted hole B1 that articulates usefulness in two shear blade A and B appropriate location, thereafter, when two shear blade A, B superimposed, wear by a special bolts C, this bolt C round bar C1 of place is embedded among the circular hole A1, and being milled with the parallel C2 of place, C1 top, round bar place embeds in the lump among the slotted hole B1, and some is piercing in another shear blade B to make the bolt C front end screw thread C3 of place, be locked to a suitable elasticity by a jam nut D again, and can make two shear blade A, B realize holding cutting purpose.

Because the nut D screw thread D1 of place is provided with plastic material, so must lean on switching instruments such as sleeve or the spanner lock of can outwarding winding in the fashion of locking, if excessively will cause two shear blade A, B tension and revolve lock, do not acquire a certain degree and to cause two shear blade A, B can't keep suitable adaptation if revolve lock, the puzzlement of " increase one fen too tight, minus fifteen too pine " so have, can influence like this and hold the convenience of cutting operation, and it is slow too to make dress lock process.

The purpose of this utility model is to provide a kind of garden shears, refers to have the garden shears of the adjustable rotary-locking device of the sound especially.

The purpose of this utility model is to realize like this, it provides a kind of garden shears, it has the adjustable rotary-locking device of the sound, it respectively is provided with the circular hole and the slotted hole of pivot joint in two shear blade appropriate locations, and on the quarter butt position of another shear blade institute rivet clasp riveting one spring leaf again, when the superimposed assembling of two shear blades, wear by a special bolts, this bolt round bar place is embedded in the shear blade circular hole, the parallel place that system is milled on the top at the round bar place embeds in the set slotted hole of another shear blade in the lump, and make the bolt front end the screw thread place some wear and expose, lock in the screw thread place of this bolt again by a special nut, make two shear blades realize holding cutting, this spring leaf itself is provided with a perforation circle, the circular hole part upwarps slightly, aligns with the central point of two shear blade articulated sections in its center of circle, and the spring leaf outer shroud is provided with the convex setback more integratedly; Special nut is provided with little ora terminalis foremost, is embedded in the perforation circle of spring leaf, makes spring leaf keep the location, and special nut is positioned at the equidistant circular row of stage casing ora terminalis setback shape thing; Rotation lock is advanced special nut can make setback shape thing contact with the setback that spring leaf is provided with convex.

The advantage of the utility model garden shears is that it makes easily assembled, processing ease, and assembling is quick, and holds to close and launch flexibly.

Below in conjunction with description of drawings the utility model garden shears, wherein:

Fig. 1 is the three-dimensional exploded view of existing scissors;

Fig. 2 A is the partial sectional view of the utility model scissors;

Fig. 3 is the stereogram of the utility model scissors.

At first, please cooperate and consult shown in Fig. 2,3, garden shears of the present utility model have the adjustable rotary-locking device of the sound; It is mainly in two

shear blades

2,3 appropriate location respectively is provided with circular hole 21 and the slotted hole 31 that articulates usefulness, pull piece 4 in a shear blade 2 rivetings one wherein again, this is pulled piece 4 and establishes a recess 41 in the appropriate position, for closing to hold together to arrest if use with the quarter butt 32 that is positioned at 3 rivet clasps of another shear blade, and on the position of quarter butt 32 pivot riveting one spring leaf 5 again, and when two shear blades 2, during 3 superimposed assemblings, wear by a special bolts 6, these bolt 6 round bar places 61 are embedded in the circular hole 21 of

shear blade

2,61 tops, round bar place are milled with parallel place 62 and then embed in the lump in the set slotted hole 31 of another shear blade 3, and make bolt 6 front ends screw thread place 63 some pass shear blade 3, lock in the screw thread place 63 of this bolt 6 by a special nut 7 again, and make two

shear blades

2,3 reach gripping prunes purpose; Particularly these spring leaf 5 tools own are provided with a perforation circle 51, upwarp slightly, and its center of circle align with the central point of two shear blades, 2,3 articulated sections, and the outer shroud 52 of spring leaf 5 is provided with convex setback 521 integratedly; Special in addition nut 7 is provided with small end edge 71 foremost, can be embedded in the perforation circle 51 of spring leaf 5, spring leaf 5 keeps the location, special nut 7 is positioned at the equidistant again circular row setback shape thing 721 of ora terminalis 72 in stage casing, when rotation lock enters special nut 7, to force setback shape thing 721 contact (shown in Fig. 2 A) with spring leaf 5 made convex setback 521 of establishing, and send the sound of rattling away, lock will can make two

shear blades

2,3 tightr more more inward, the user also can utilize its function, directly comes the appropriate regulation garden shears to be beneficial to trimming leaf with hand.
