Abstract

The utility model relates to a can multi-angle change high altitude of shearing direction cut. It mainly comprises scissors consisting of blades (11) and (12), a long rod (15), a turning arm (16), a pulley block (13), a pull rope (18) and a spring (17). It is characterized in that the turning arm and the long rod are rotated and swung by using a connecting bolt (20) as an axis to change the connecting angle of the turning arm and the long rod so as to change the angle between the shearing surface of the scissors and the long rod, so that a person can prune branches growing at high altitude along different directions on the ground.

Description

Aerial shears with adjustable angle

本实用新型涉及一种人在地面即可进行高空剪枝的剪刀，尤其是能够多角度改变剪切方向的高空剪枝剪刀。The utility model relates to a pair of scissors that can be used for high-altitude pruning by people on the ground, in particular the high-altitude pruning scissors that can change the cutting direction at multiple angles.

目前园林人员使用的一种高空剪，其结构如图1所示，在勾把体1上部由轴3和弹簧4连结刀片2，勾把体1下端连接一长杆5，拉绳8穿绕于设置在勾把体上之滑轮7和刀片上之滑轮6。使用时一手握长杆5，以勾把体之勾形部位勾住树枝，另一手拉动拉绳8使刀片2旋摆剪切树枝。此种高空剪虽然解决了不用爬上树即可修剪高处树枝问题，但由于该结构之剪刀的剪切面与长杆呈固定的平行状态，因此只能修剪与举起的剪刀呈垂直方向的枝干，降低了该剪刀的使用效率。A high-altitude shear currently used by gardeners has a structure as shown in Figure 1. A shaft 3 and a spring 4 are connected to the blade 2 on the upper part of the hook body 1, and a long rod 5 is connected to the lower end of the hook body 1, and a pull rope 8 is threaded around it. Be arranged on the pulley 7 on the hook body and the pulley 6 on the blade. When using, hold the long pole 5 with one hand, hook the branch with the hook-shaped part of the hook body, and pull the stay cord 8 with the other hand to make the blade 2 swivel to cut the branch. Although this kind of high-altitude shears solves the problem of trimming high branches without climbing up the tree, but because the shearing surface of the scissors of this structure is fixedly parallel to the long pole, it can only be trimmed perpendicular to the lifted scissors. The branches reduce the use efficiency of the scissors.

本实用新型的目的是要提供一种适于修剪各种角度生长的枝干的高空剪。The purpose of the utility model is to provide a high-altitude shear suitable for trimming branches growing at various angles.

本实用新型是按如下结构制成的：The utility model is made according to the following structure:

将具有两只刀片所组成的通用结构形式的剪刀之一只刀片柄部与一长杆藉转折臂相连结，通过改变转折臂与长杆之间的连结角度而改变剪刀之剪切面与长杆间之角度；在剪刀之另一刀片上挂设一弹簧并勾连在转折臂上，在剪刀之两刀片柄端及转折臂上安装有滑轮组，拉绳先绕置于两刀片柄端之滑轮上，再绕至转折臂上之滑轮而下，拉绳末端绕嵌在一握把上。一手持长杆，一手拉动拉绳即可进行剪枝操作。而通过改变转折臂与长杆的连结角度，即可实现剪切各种不同方向生长的枝干。Connect one blade handle of scissors with a general structure composed of two blades to a long rod through a turning arm, and change the shearing surface and length of the scissors by changing the connection angle between the turning arm and the long rod. The angle between the rods; hang a spring on the other blade of the scissors and hook it to the turning arm. A pulley block is installed on the handle ends of the two blades of the scissors and the turning arm. The pull cord is first wound around the pulleys at the handle ends of the two blades. Go up, then go around to the pulley on the turning arm and go down, the end of the pull rope is wrapped around a handle. Hold the long pole in one hand and pull the drawstring with the other hand to perform pruning operations. By changing the connection angle between the turning arm and the long pole, it is possible to cut branches growing in various directions.

本实用新型因具有可以改变角度的转折臂结构，能进行多角度之高空剪切操作，使用起来极其方便，有效地改进了惯用高空剪的使用性能，而不再受树木枝干生长方向的限制；且由于有握把设置，使手拉动拉绳进行剪切动作更为安全可靠。Because the utility model has a turning arm structure that can change the angle, it can perform multi-angle high-altitude shearing operations, which is extremely convenient to use, effectively improves the performance of the conventional high-altitude shears, and is no longer limited by the growth direction of tree branches ; And due to the handle setting, it is safer and more reliable to pull the drawstring by hand to perform the cutting action.

下面结合附图对本实用新型之结构作进一步详细描述。Below in conjunction with accompanying drawing, the structure of the present utility model is described in further detail.

参照图2至图4，由刀片[11]、[12]组成通用结构之剪刀，刀片(11)柄部与转折臂(16)之一端相连接，并使转折臂[16]与剪刀剪切面呈垂直状态固定安装于刀片[11]柄部，转折臂[16]之另一端与长杆[15]通过螺栓[20]相连接，转折臂[16]与长杆[15]以连接螺栓[20]为轴旋摆可变换其连接角度，并由螺栓[20]、[21]夹固长杆[15]，刀片[12]上挂设弹簧[17]与转折臂[16]勾连，在刀片[11]、[12]之柄端安装滑轮组[13]，在转折臂[16]上安装滑轮[14]，拉绳[18]先绕置于滑轮组[13]上，再绕至滑轮[14]而下，拉绳[18]末端绕嵌在握把[19]上。With reference to Fig. 2 to Fig. 4, by blade [11], [12] form the scissors of general structure, blade (11) shank is connected with the end of turning arm (16), and makes turning arm [16] and scissors cut The surface is vertical and fixed on the handle of the blade [11]. The other end of the turning arm [16] is connected with the long rod [15] through a bolt [20]. The turning arm [16] and the long rod [15] are connected by bolts. [20] can change its connection angle for the axle swing pendulum, and by bolt [20], [21] clamp long bar [15], hang spring [17] on the blade [12] and link with turning arm [16], Install pulley block [13] at the shank end of blade [11], [12], install pulley [14] on turning arm [16], stay rope [18] is wound on the pulley block [13] first, then winds to pulley [14] and down, stay cord [18] end is embedded on the handle [19] around.

当不工作时，由于弹簧[17]的作用使刀片[11]、[12]呈张开状态；当工作时，拉动拉绳[18]即可使刀片动作，实现剪切工作。参照图4所示，当使转折臂[16]与长杆[15]呈垂直状态连接时，则剪刀之剪切面与长杆[15]呈平行状态，此时人在地面一手持长杆[15]，一手拉动拉绳[18]，可以很方便地剪切高空中与地面呈平行方向的枝干；参照图5所示，当使转折臂[16]与长杆[15]呈45°角状态连接时，则剪刀之剪切面与长杆[15]呈45°角状态，此时可方便地剪切高空中与地面呈45°左右角度的枝干；参照图6所示，当使转折臂[16]与长杆[15]呈平行状态连接时，则剪刀剪切面与长杆[15]呈垂直状态，此时，可方便地剪切高空中与地面相垂直的枝干。When not working, because the effect of spring [17] makes blade [11], [12] be open state; When working, pulling stay cord [18] can make blade action, realizes cutting work. Referring to Figure 4, when the turning arm [16] is connected to the long pole [15] in a vertical state, the shear plane of the scissors is parallel to the long pole [15]. [15], pulling the stay rope [18] with one hand can easily cut the branches parallel to the ground in the sky; When the angle state is connected, the shearing surface of the scissors and the long rod [15] are in a 45° angle state, and at this moment, the branches at an angle of about 45° in the sky and the ground can be easily cut; as shown in Fig. 6, When the turning arm [16] is connected to the long pole [15] in a parallel state, the shearing surface of the scissors is perpendicular to the long pole [15]. Dry.
