specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, a kind of secondary gear type reciprocating scissors described in this embodiment includes upper blade main body 1, lower blade main body 2, several upper cutting edges 3 and several lower cutting edges 4, upper blade main body 1 and lower blade main body 1 and lower blade main body 2. The blade body 2 is stacked from top to bottom, and one side of the upper blade body 1 is provided with several upper cutting edges 3 along its length direction, and each upper cutting edge 3 is connected with one side of the upper blade body 1 to form a One side, one side of the lower blade main body 2 is provided with several lower cutting edges 4 along its length direction, and each lower cutting edge 4 is connected with one side of the lower blade main body 2, and the upper cutting edge 3 and The edge of the lower cutting edge 4 is provided with several auxiliary teeth 5 .

specific Embodiment approach 2

[0016] Specific implementation mode two: combination Figure 1 to Figure 3 To illustrate this embodiment, the upper cutting edge 3 and the lower cutting edge 4 of a pair of auxiliary tooth type reciprocating scissors described in this embodiment are both isosceles triangles, and between the centerlines of two adjacent isosceles triangles The distance L1 is 90mm, the height H of each isosceles triangle is 115mm, and the width W of the isosceles triangle is 36.99mm. Such setting can effectively prevent the upper cutting edge 3 and the lower cutting edge 4 from slipping off due to the short length of the upper cutting edge 3 and the lower cutting edge 4, thereby providing sufficient cutting stroke. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0017] Specific implementation mode three: combination Figure 1 to Figure 3 To illustrate this embodiment, there is a gap D between the lower surface of the upper blade main body 1 and the upper surface of the lower blade main body 2 of the auxiliary tooth type reciprocating scissors in this embodiment, and the gap D is 0.5 mm. Such arrangement effectively avoids friction between the upper blade main body 1 and the lower blade main body 2, which affects the overall service life of the scissors. Other components and connections are the same as those in the first embodiment.

Abstract

The invention provides secondary tooth reciprocating scissors, relates to reciprocating scissors, in particular to the secondary tooth reciprocating scissors. In order to solve the problem that in theprocess of trimming grape side shoots, hedges, lawns and the like, cut branches or strips often slip off from shearing blades, which causes cutting leakage phenomenon of the trimmed hedges, the lawnsand the like. The scissors comprise an upper blade body, a lower blade body, a plurality of upper cutting blades and a plurality of lower cutting blades, the upper blade body and the lower blade bodyare superposed from top to bottom, one side of the upper blade body is provided with the upper cutting blades in the length direction, each upper cutting blade is integrally connected with one side of the upper blade body, one side of the lower blade body is provided with the lower cutting blades in the length direction, each lower cutting blade is integrally connected with one side of the lowerblade body, and the edges of the upper cutting blades and the lower cutting blades are provided with a plurality of secondary teeth. The scissors belong to the field of forestry machinery.

Description

technical field [0001] The invention relates to a reciprocating scissors, in particular to an auxiliary tooth type reciprocating scissors, belonging to the field of forestry machinery. Background technique [0002] In order to make plants grow according to the specified shape, forestry workers often have to trim various vegetation, and in the process of trimming grape auxiliary shoots, hedges, lawns, etc., the cut branches or strips It often slips from between the cutting blades, resulting in missed cutting of the trimmed hedges and lawns. Contents of the invention [0003] The present invention aims to solve the problem that during the pruning operation of grape auxiliary shoots, hedges, lawns, etc., the cut branches or strips often slip from between the cutting blades, resulting in missing pruning of the pruned hedges, lawns, etc. phenomenon, and then propose a pair of teeth type reciprocating scissors. [0004] The technical solution adopted by the present invention t...
