Abstract

(57) [Summary] [Purpose] The mooring can be done safely and surely without disturbing the usability of the driver, and it is adapted regardless of the type and thickness of the driver. [Structure] A loop 1a is formed at both ends of the wire 1. The caulking base of the loop 1a is a heat-shrinkable tube 1.
It is covered with b. A rotating ring 2 is attached to the loop 1 a on one end side of the wire 1. The rotating ring 2 has a through hole 2a formed therein, and the loop 1a is connected to the through hole 2a. The rotary ring 2 is fitted into the shaft d1 of the driver D, but the rubber stopper 3 is elastically fitted so that the rotary ring 2 does not come out of the shaft d1 of the driver D, and the rotary ring 2 is fitted into the driver D. It is held by loosely sandwiching it with the handle d2. The loop 1 a at the other end of the wire 1 is attached to the tool holder 5 via the connection ring 4. The tool holder 5 is attached to a body attachment portion such as a safety belt wrapped around the body of the operator.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment for keeping a driver moored to an operator's body.

[0002]

[Prior art]

 The screwdriver as a fastener is used at all work sites, but especially in high-altitude work, there is a risk of accidents and loss due to the driver falling, so the development of effective mooring means. Was requested.

[0003]

[Problems to be solved by the device]

 The present invention has been made in response to the above-mentioned conventional demands, and the purpose thereof is to enable mooring safely and surely without hindering the usability of the driver, and to determine the type and thickness of the driver. It is to provide a driver mooring attachment that can be adapted regardless.

[0004]

[Means for Solving the Problems]

 The driver mooring attachment of the present invention comprises a wire moored to a body mounting part such as a tool holder; a rotary ring attached to the tip of the mooring wire and rotatably inserted around the shaft of the driver; And a stopper of an elastic material which is loosely sandwiched between the handle and the handle of the driver to prevent the rotating ring from coming off the shaft.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a wire, and loops 1a are formed at both ends thereof. The caulking base of the loop 1a is covered with a heat shrinkable tube 1b. The wire 1 is preferably a stainless steel wire rod having a high tensile strength of 20 kg or more, which is rich in flexibility, but is not limited to this. Any non-metallic wire such as plastic or carbon fiber may be used as long as the wire does not interfere with the usability. Also, the loop 1a at the end is not limited to this, and may have a structure that is firmly connected to a tool holder or a rotating ring described later (removably connected to the tool holder).

A rotating ring 2 is attached to the loop 1 a on one end side of the wire 1. In the present embodiment, the rotating ring 2 is made of a hard plastic material having a smooth surface, but the shaft of the driver passing through the rotating ring 2 can be smoothly rotated, and is made of a lightweight material that is not easily worn. Any material may be used as long as it is available. A through hole 2a is formed in the rotary ring 2, and the loop 1a is connected to the through hole 2a. The connecting structure of the rotating ring 2 and the wire 1 is not limited to the above.

As shown in FIG. 2, the rotary ring 2 is fitted into the shaft d1 of the driver D, but the rubber stopper 3 is elastically attached so that the rotary ring 2 does not come out of the shaft d1 of the driver D. 3 and then, as shown in FIG. 3, the rotating ring 2 is loosely sandwiched between the rotary ring 2 and the handle d2 of the driver D and moored.

The loop 1 a at the other end of the wire 1 is attached to the tool holder 5 via the connection ring 4. The tool holder 5 is hooked on a safety belt (not shown) wrapped around the body of the operator. The wire 1 may be directly moored to the safety belt or other body attachment part.

Since the stopper 3 is made of an elastic material such as rubber, it can be adapted even if the thickness of the shaft d1 of the driver D 1 is slightly changed, and a plus type as in this embodiment. Not only the driver D but also a minus type driver can be attached by, for example, crushing the elastic stopper 3 with a finger to transform the hole into an oblong shape and then inserting the hole. Also, in order to accommodate changes in the shaft thickness of the driver D and the shape of the cutting edge, the hole of the rotary ring 2 was made slightly larger, or the shape of the hole was changed as shown in FIG. The rotating ring 2'may be used, in particular to accommodate negative blade edges.

[0010]

[Effect of device]

 1) Since the driver is moored by the rotating ring, the wire does not get tangled even when the driver is rotated. 2) Since a stopper made of an elastic material is used, mooring is possible with either positive or negative screwdrivers with slightly different shaft thicknesses or different blade types. 3) By using a rotating ring with a slightly deformed hole shape, mooring is possible with either positive or negative screwdrivers with different blade types. 4) Since the wire is highly flexible, it is convenient for the driver and can be moored safely.
