Summary of the invention
The present invention is in order to solve in existing technique, needing when pruning the branch of eminence to utilize ascending tool or free-hand climbing to carry out pruning the problem causing cut operation very inconvenient to tree, the object of the present invention is to provide a kind of telescopic pruning bar being applicable to eminence and pruning.
The invention provides base case is: telescopic pruning bar, comprise expansion link, detent mechanism and cutting mechanism, wherein, described expansion link comprises upper rack posts and lower fulcrum bar, described upper rack posts is hollow stem, described upper rack posts is socketed in the outside of described lower fulcrum bar, the lower end of described upper rack posts is connected with described detent mechanism, described detent mechanism comprises connecting rod and backstay, one end of described connecting rod is connected to the outer wall of described upper rack posts, the described connecting rod other end and described backstay hinged, described connecting rod is provided with locating slot, one end of described backstay and described rod hinge connection is provided with positioning end, the length of described positioning end is greater than the length of described locating slot, described backstay is provided with holding end away from one end of described connecting rod, described cutting mechanism comprises motor and disk, the center of described disk is provided with connecting hole, described connecting hole is connected with the output shaft of described motor, described disk is evenly provided with sawtooth, described motor is arranged on the top of described upper rack posts, described motor is connected with switch by cable, described switch is positioned at the lower end of described lower fulcrum bar.
The operation principle of base case: when needing to prune the branch of eminence, stir backstay, positioning end is made to be positioned at locating slot outside, pull upper rack posts, when the length of the expansion link that upper rack posts and lower fulcrum bar form is enough, stop drag connecting rod, stir backstay, the positioning end of backstay is made to slip into locating slot, because the length of positioning end is slightly larger than the length of locating slot, after positioning end slips into locating slot, positioning end is to the upper rack posts force of contact, the part contacted with positioning end is made inwardly elastic deformation to occur, thus the lower fulcrum bar of upper rack posts inside is clamped, after upper rack posts and lower fulcrum bar no longer slide, cutting mechanism is delivered to need prune branch below, close switch, electric motor starting, the output shaft rotation of motor, disk rotational, sawtooth moves thus prunes branch, after pruning, cut-off switch, motor decommissions, the output shaft of motor stops operating, after disk stops operating, sawtooth stops the pruning to branch.
The beneficial effect of base case is: by arranging upper rack posts and lower fulcrum bar, utilize the mutual slip composition expansion link between upper rack posts and lower fulcrum bar thus the branch of eminence is pruned, without the need to climbing to a higher point by ascending tool, simplify cut operation, and when pruning bar and leaving unused, after again stirring backstay, upper rack posts can be slided, thus reduce the placement space pruning bar.
Preferred version one: based on scheme preferred, described positioning end is provided with arc end; Beneficial effect: by arranging arc end, facilitates positioning end and slips into locating slot.
Preferred version two: preferably one preferred, the outside of described motor is provided with shell; Beneficial effect: by arranging shell to motor, protection motor can not be subject to outside wearing and tearing.
Preferred version three: preferably two preferred, the inwall of described upper rack posts bottom is provided with transverse slat, and the sidewall of described lower fulcrum bar upper surface is provided with breast board; Beneficial effect: by arranging transverse slat and breast board, prevents upper rack posts from the upper end slippage of lower fulcrum bar.
Excellent alternative four: preferably three preferred, the hinged place of described backstay and described connecting rod is provided with bearing; Beneficial effect: by arranging bearing in the hinged place of backstay and connecting rod, reduces the wearing and tearing that backstay is subject in the process of rotating, thus extends the service life of backstay.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's telescopic pruning bar embodiment.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: upper rack posts 101, lower fulcrum bar 103, transverse slat 105, breast board 107, connecting rod 109, backstay 113, positioning end 115, holding end 117, motor 201, disk 203, output shaft 205, sawtooth 207, shell 209.
Telescopic pruning bar as shown in Figure 1, comprise expansion link, detent mechanism and cutting mechanism, expansion link comprises upper rack posts 101 and lower fulcrum bar 103, upper rack posts 101 is hollow stem, upper rack posts 101 is socketed in the outside of lower fulcrum bar 103, the inwall of upper rack posts 101 bottom is provided with transverse slat 105, the sidewall of lower fulcrum bar 103 upper surface is provided with breast board 107, the lower end of upper rack posts 101 is connected with detent mechanism, detent mechanism comprises connecting rod 109 and backstay 113, one end of connecting rod 109 is connected to the outer wall of upper rack posts 101, connecting rod 109 other end and backstay 113 hinged, backstay 113 is provided with bearing with the hinged place of connecting rod 109, connecting rod 109 is provided with locating slot, backstay 113 one end hinged with connecting rod 109 is provided with positioning end 115, positioning end 115 is provided with arc end, the length of positioning end 115 is greater than the length of locating slot, backstay 113 is provided with holding end 117 away from one end of connecting rod 109, cutting mechanism comprises motor 201 and disk 203, the center of disk 203 is provided with connecting hole, connecting hole is connected with the output shaft 205 of motor 201, , disk 203 is evenly provided with sawtooth 207, motor 201 is arranged on the top of upper rack posts 101, the outside of motor 201 is provided with shell 209, motor 201 is connected with switch by cable, switch is positioned at the lower end of lower fulcrum bar 103.
