Embodiment Construction

[0032] Hereinafter, the tip tool connection structure according to the embodiment of the present invention will be described with reference to the drawings. First, use figure 1 , the structure of the present invention is described, referring to figure 2 Describe the function.

[0033] refer to figure 1, The front-end tool coupling structure 1 is composed of the plug portion 7 of the front-end tool 2 and the coupling member 20 provided on the front-end side of the remote operation lever 12 . Here, for convenience of description, a part of the link 20 and the remote control lever 12 is shown in cutaway so that the internal structure can be easily understood.

[0034] like figure 1 As shown, the direction when the plug portion 7 is fitted to the coupling member 20 is taken as the hand side in the longitudinal direction of the remote control lever 12 and indicated by an arrow, and similarly, the direction when it is separated is taken as the front end of the remote control...

Abstract

To provide a tip tool connection structure capable of quickly and reliably replacing a tip tool even with a remote operation lever composed of a plurality of levers, and maintaining good insulation with a simple structure. The front-end tool connecting structure (1) is composed of a connecting piece (20) at the front end of the remote operating rod (12) and a plug portion (7) of the front-end tool (2). The plug part (7) has an annular groove (7a) and a fitting shaft (7b). The connecting piece (20) is composed of a plug receiving piece (22) on the front end side and a tube portion (30) on the hand side. A lock ball (26a) embedded in a case portion (26) of a plug receiver (22) is pressed in a diameter-reducing direction by an inward protrusion (28b) of an outer sleeve portion (28). The locking ball (26a) is inserted into the annular groove (7a) to lock the connection state. The insertion portion (18a) is inserted into the remote control lever (12) in a state where the flange portion (18b) of the plug body (18) is engaged with the opening edge. The cylindrical portion (30) is arranged to cover the remote control lever (12) and the flange portion (18b).

Description

technical field [0001] The present invention relates to a front-end tool connection structure, which is replaceably connected to a long-distance operation tool for safely operating components such as a high-voltage stringing from a long distance during wire-strapping construction. Front-end tools. Background technique [0002] Image 6 An example of a conventional remote operation handle 100 is shown in . In wiring construction, when performing live wire work, it is necessary to insulate the hand side from the work object. Therefore, the main lever 114 and the sub lever 116 of the remote control lever 112 generally use an electrically insulating FRP material (fiber-reinforced composite material) or the like. [0003] However, even if it is made of an insulating material, when working in rainy weather, rainwater may flow from the front end side to the hand side to cause a conductive accident. Therefore, if Image 6 As shown, umbrella-shaped rain shields 101 are provided at...
