Description

A kind of sliding Labour-saving tree pruner
Technical field
The utility model relates to a kind of gardens pruning instrument, specifically a kind of sliding the averruncator sheared by pulling.
Background technology
Averruncator is a kind of widely used gardens gardening pruning tools.Averruncator design now is also varied.If publication number is the Chinese patent of CN201320501628, CN99104224, CN201320857176, CN98234861, but these designs are all the bar outer setting lever labor-saving devices at averruncator, one is increase on top to cut arm lengths, two is increase decreased food in bottom, but this structure takies larger space, easily stumble on top and pull branch impact use, need larger operating space in bottom, and force direction is inconsistent with the axis direction with bar, impact operation holds.The Chinese patent that publication number is CN201110128011 have employed pneumatic means and provides shearing, overcome above-mentioned patent and take larger space outerpace defect, but this design connects high-pressure air pipe generation involves impact operation, but also needs special pressure-air feeding mechanism.Publication number is that the Chinese patent of CN201320247601 adopts pulley mode laborsaving, designs ingenious.But this design can only economize 2 times of power, therefore have to adopt lever force-saving mode to increase shearing on top, and tension spring (back-moving spring) is in outside, not compact and easily stumbled and pull damage, in addition, the part pulley of this design and be located at outside, pulley and stay cord are easily fallen slag branches and leaves fork clip.Further, stay cord causes very large resistance and easy damaged stay cord by the design that narrow slit passes.
Summary of the invention
In order to solve the problem, the utility model provides a kind of work-saving device and does not take space outerpace, and force direction during use is consistent with holding rod direction, easy to operate and the one of laborsaving multiple can be regulated as required sliding Labour-saving tree pruner.
The technical solution adopted in the utility model is: a kind of sliding Labour-saving tree pruner, comprises holding rod, sliding handle, drive link, back-moving spring, pulley assembly, cutting head.Described holding rod is a long tube, is provided with a hanging sleeve in holding rod one end, and the tube wall of the other end has screw hole, tube wall be provided with by axis to wearing chute.Described sliding the shaped piece that holds a writing brush or pen-write for proficiency, have one to slide and pin rod radial direction is connected to two walls to wearing, sliding being socketed on holding rod.
Described pulley assembly comprises movable pulley, fixed pulley, movable pulley installed part, fixed pulley installed part.Movable pulley can be one or more, is installed on movable pulley installed part, and can be slided in handle by movable pulley installed part.Fixed pulley can be one or more, is installed on fixed pulley installed part, and is fixedly connected in holding rod by fixed pulley installed part.Pull rope one end is connected to movable pulley or fixed pulley installed part, and the other end is connected to the sliding pin rod of sliding handle after walking around each pulley successively by the mode of helix.As shown in Figure 4, pulley assembly can be: 1. form by a fixed pulley and a movable pulley combination economizing three times of power; 2. form by a fixed pulley and two movable pulleys the combination economizing four times of power; 3. form by two fixed pulleys and two movable pulleys the combination economizing four times of power or economize five times of power, and by that analogy, the pulley assembly of the more multiple power of province can be obtained.Holding rod axially-aligned pressed by the pulley of movable pulley connector and fixed pulley connector, and each wheel shaft is parallel to each other.
After installing multiple pulley, by principle shown in accompanying drawing 4, pulley number that draught line walks around can be reduced as required to change laborsaving multiple.
Described drive link is a rod-like element, is provided with a block plate in the middle part of drive link.Described back-moving spring is the stage clip of a loading holding rod.The inner end of drive link is connected to movable pulley installed part, and back-moving spring is placed on drive link, and one end heads on movable pulley installed part, and the other end heads on the block plate of drive link, and the outer end of drive link is used as power output.The pull rope of pulley assembly pulls movable pulley installed part by sliding traction, thus drives drive link outputting power, unclamps slidingly the effect due to back-moving spring is imposed opposition to pulley assembly to make sliding resetting.Back-moving spring also plays tension to pulley assembly.Due to the power-saving function of pulley assembly, according to pulley combination situation, the power that drive link exports can be greater than to be applied to be slided three of power times, four times or five times, and more times.
Described averruncator cutting head is the shearing work portion of averruncator, comprises connector, chute, slide plate, dead knife, movable blade.Connector is a tube-like piece, is socketed on holding rod end, and one end of connector connects chute, and the side of chute is connected and fixed cutter.Slide plate slips with described chute, and slide plate top connects movable blade, and is connected to the outer end of drive link.Pull sliding handle, after laborsaving by assembly pulley, pull movable blade, make movable blade staggered with dead knife laminating, realize shearing.
The course of work of the present utility model is: at off position, because drive link is pushed into front end by the effect of back-moving spring, simultaneously by the pull rope tensioning of pulley assembly and by cunning being pulled to chute one end, to sliding handle and drive link location.During work, pull sliding handle, affect pulley assembly by pull rope, after laborsaving, pull drive link, export pulling force.The sliding handle of release, under the effect of back-moving spring, drive link resets with sliding.
The beneficial effects of the utility model are:
1) sliding the power can economizing more than three times, and the number that can draught line selected as required to walk around pulley selects different laborsaving multiples.
2) all effort-saving mechanisms are all in holding rod, and work-saving device does not take space outerpace.
3) do not have lever arm, force direction during cut operator is consistent with holding rod direction, greatly facilitates operation.
4) because pulley is by holding rod axially-aligned, pulley and draught line is made not to take horizontal space.
5) head of averruncator does not have labor saving arm and pull rope, overcomes general averruncator and is easily stumbled by branch extension and easily damage the shortcoming of external component.
