Abstract
The invention discloses a tool for shearing branches and leaves, and the tool can prevent blades from being tightened stubbornly. The tool comprises the two blades, two press pieces, bolts and nuts, wherein the cross section of each blade is arc-shaped; the two press pieces are fixed on the outer sides of the two blades through the bolts and the nuts; screw holes formed on the press pieces correspond to chutes on the axes of the blades; the press pieces are in slide fit with the blades; slide rings are arranged in the chutes of the blades; the height of each slide ring is twice as great as the depth of each chute, and the outer diameter of each slide ring is greater than the diameter of the screw hole on each press piece; and the slide rings are sleeved on the bolts penetrating through the chutes and are in slide fit with the inner walls of the chutes. By utilizing the structure with the slide rings arranged in the chutes, when the bolts are screwed to the utmost degree, the blades can not be further tightened due to the limitation of two ends of each slide ring, therefore the pressure borne by the blades reaches the limit, and the blades can be prevented from being tightened stubbornly.
Description
Technical field
The present invention relates to a kind of cutter of shearing branches and leaves.
Background technology
The cutter of existing shearing branches and leaves is more, but the structure of blade is basic identical.The patent No. of the applicant invention is 200910074446.8 Chinese patent, and disclosing a kind of cross section is arcuate blades, solves the straight easy fouling of plate shape blade of tradition, influence cutting performance, and service life weak point defective.Traditional structure is adopted in the assembling of this blade, and promptly the two blades outside is fixed with two compressing tablets.But there is defective in this structure, when the bolt overtorquing, the pressure of two blades is increased, and has strengthened the frictional force between blade, can increase the load of motor, and not only operating efficiency reduces, also can reduction of service life, can burn motor when serious.Twist when too loose when bolt, the pressure between two blades reduces, and is easy to generate fouling, has lost the original intention that adopts cambered blade.
Summary of the invention
The purpose of this invention is to provide a kind of blade that can prevent and twisted dead branches and leaves shearing tool.
Technical scheme of the present invention is: comprise blade, compressing tablet, screw bolt and nut, the cross section of blade is an arc, two compressing tablets are fixed on the two blades outside by screw bolt and nut, set screw is corresponding with the chute on the blade axis on the compressing tablet, compressing tablet and blade are slidingly matched, and in the chute of described blade slip ring are housed, and the height of this slip ring is greater than the twice chute degree of depth, the external diameter of slip ring is greater than the diameter of screw on the compressing tablet, and slip ring sleeve is slidingly matched passing on the bolt of chute and with the chute inwall.
The present invention adopts is equipped with slip ring in chute, the height of this slip ring is greater than the twice chute degree of depth, the external diameter of slip ring is greater than the structure of the diameter of screw on the compressing tablet, when bolt tightens at utmost, can not further blade be pressed by the restriction of the two ends of slip ring, the suffered pressure of blade is reached capacity, prevent blade tightly dead.Therefore,, just maximum pressure can be adjusted to required optimum value, thereby guarantee that the blade pressure is in optimum state as long as select the suitable height of slip ring.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not constitute any limitation of the invention.Illustrated in figures 1 and 2, the present invention includes blade 2, compressing tablet 1, bolt 4 and nut 5, two compressing tablets 1 are fixed on the outside of two blades 2 by bolt 4 and nut 5, set screw is corresponding with the chute on blade 2 axis on the compressing tablet 1, compressing tablet 1 is slidingly matched with blade 2, and slip ring 3 is housed in the chute of described blade 2, and the height of this slip ring 3 is greater than the twice chute degree of depth, the external diameter of slip ring 3 is greater than the diameter of screw on the compressing tablet 1, and slip ring 3 is enclosed within on the bolt 4 that passes chute and with the chute inwall and is slidingly matched.During work, power traction blade 2 is reciprocating, and the cutter tooth of two blades 2 is sheared branches and leaves.At this moment, the slip ring 3 that is arranged in chute moves with compressing tablet 1 and screw rod, and two blades 2 press the glue and the foreign material that prevent in the branches and leaves and enter.The pressure that two blades are 2 is not tight more good more, by selecting the suitably slip ring 3 of height, makes the maximum pressure of 2 on two blades reach an optimum value, just can make cutter be in optimum state.
