    • The present invention relates to secateurs, which enable a trimming work of trimming the branches of fruit trees and landscape trees or various horticultural crops and a cutting work of cutting rather thick branches or various wood. The present invention provides secateurs (10), which are formed by coupling two supports (20a, 20b), which consist of gripping members (21a, 21b) and cutting members (22a, 22b) with cutter blades (23a, 23b), by a shaft pin (P). Fasteners (25) are arranged on one of the supports (20a, 20b). Coupling holes (31) of a saw (30) with a cutting saw blade (32) are coupled to the fasteners (25). Fastening means (26) are respectively coupled to ends of the fasteners (25) which pass through the coupling holes (31) of the saw (30) such that the saw (30) can be attached to or detached from the supports (20a, 20b). The present invention can improve the efficiency of the trimming work by enabling a sawing work anytime during the trimming work and can improve storability and portability by enabling the disassembly of the saw from the supports.
    • 本发明涉及剪羊皮,其能够修剪果树,景观树木或各种园艺作物的分枝,以及切割相当厚的枝条或各种木材的切割工作。 本发明提供了通过将由夹持构件(21a,21b)和切割构件(22a,22b)组成的两个支撑件(20a,20b)通过与切割刀片(23a,23b)组合而形成的修剪器(10),通过 轴销(P)。 紧固件(25)布置在支撑件(20a,20b)中的一个上。 具有切割锯片(32)的锯(30)的联接孔(31)联接到紧固件(25)。 紧固装置(26)分别联接到穿过锯(30)的联接孔(31)的紧固件(25)的端部,使得锯(30)可以从支撑件(20a, 20B)。 本发明可以通过在修剪作业期间随时进行锯切工作来提高修剪工作的效率,并且可以通过使支撑件拆卸锯来提高保存性和便携性。

    • A measuring instrument for the length of a stiffener in a ground is provided to be applicable to ground reinforcement process to secure quality of construction by accurately inspecting the construction. A measuring instrument(100) for a length of a stiffener in a ground includes a punched hole(10), a stiffener(20), a measurement unit(30), and a coupling member(40). The measuring instrument is inserted into the punched hole for a ground reinforcement. The measuring unit is located in parallel to a lengthwise of the stiffener for measuring the length of the stiffener. The coupling member connects the stiffener and measurement unit. The measuring unit includes a cap, a cover, and a wire. The cap limits a front movement of the wire to protect the wire. The cap is coupled to the cover and receives the wire therein to be fixed to the stiffener by using the coupling member.
