Description

A kind of scissors for clearing hanging string kites

technical field

The invention relates to a pair of scissors, in particular to a pair of scissors for clearing high-altitude hanging objects, and belongs to the technical field of electric power construction auxiliary equipment.

Background technique

There are often kites hanging on the outdoor high-altitude cables, which pose a certain danger to the cables. There is no special tool for removing the hanging kite in the existing insulating tools and utensils. Usually, the insulating operating rod is used to dismantle the hanging kite body, and the kite line wound on the wire, hardware or equipment is used to wrap, slam There are two problems in this cleaning method: one is that the kite may be charged due to the connection between the hanging kite and the charged body, and the kite line has the characteristics of dancing with the wind. When removing kites with insulating operating rods, methods such as violent falling are often used, and the work is not safe; second, because the materials used in kites include skeletons, paper or cloth, and wires, etc., and the structure is messy, use insulating operating rods to dismantle and remove kites Not easy to control, difficult and time consuming.

Contents of the invention

The technical problem to be solved by the present invention is to provide a pair of scissors for clearing the string kite against the defects of the prior art, so as to solve the problem of tearing apart the string kite skeleton and removing the kite string winding on wires, fittings or equipment.

In order to solve this technical problem, the present invention provides a kind of scissors for clearing hanging kites, comprising a hollow connecting rod, scissors and an operating handle mechanism, the scissors include dynamic scissors and fixed scissors hinged together, The head of the curved knife is a curved knife, and the curved knife is provided with a retracting groove near the front end. The tail end of the fixed scissors 8 is fixed on the upper part of the hollow connecting rod; The rod is hinged, and the other end of the connecting rod is connected with the operating handle mechanism located in the hollow connecting rod, and the operating handle mechanism controls the opening and closing of the brake scissors and the fixed scissors.

The operation handle mechanism includes a pull rod, a pull rope, a pull rod handle and a return spring. The pull rod is located inside the hollow connecting rod, and the pull rod handle is arranged at one end of the operation handle to connect with the pull rod. A back-moving spring is arranged between the connecting rod and the pull bar. Pulling the pull bar handle with the operating handle as a fulcrum can drive the connecting rod through the pull bar and the pull cord and then drive the moving scissors to control the opening and closing of the scissors, and the back-moving spring makes it reset.

The frontmost part of described movable scissors and fixed scissors is provided with sharp jaws, and the jaw of movable scissors retracts 5-8mm than the jaw of fixed scissors, guarantees that moving scissors and fixed scissors overlap when cutting.

Anti-slip lines are provided on the facing surfaces of the pointed jaws.

The hollow connecting rod, the operating handle and the pull rod handle are made of insulating materials.

Beneficial effects: the present invention uses curved scissors to gather the hanging kite into the opening of the scissors, breaks down the skeleton and releases the kite line and paper/cloth on the wires, fittings or equipment, processes the kite in sections, and passes through the clip located at the front end. The jaws are removed to reduce the difficulty of operation, which can avoid safety accidents caused by violently dropping the kite, and has the advantages of good safety, convenient operation, and time and labor saving.

Detailed ways

The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 shows the structural representation of the present invention.

The invention includes a hollow connecting rod 1, scissors and an operating handle mechanism, the operating handle mechanism is located in the hollow connecting rod 1, and the scissors are located in the head of the hollow connecting rod 1 and connected with the operating handle mechanism.

Described scissors comprise movable scissors 7 and fixed scissors 8 that are hinged together.

Figure 2 is an enlarged schematic view of part A of the scissors head of the present invention.

The head of the fixed scissors 8 is a curved knife, and the curved knife is provided with a draw groove 10 near the front end, so that it is convenient to control the high-altitude kite material not to move out of the scissors, which is convenient for operation.

The tail end of the fixed scissors 8 is fixed on the top of the hollow connecting rod 1 .

The head of the moving scissors 7 is a straight knife, and its tail end is hinged with the connecting rod 6, and the other end of the connecting rod 6 is connected with the operating handle mechanism located in the hollow connecting rod 1, and the operating handle mechanism controls the moving scissors. 7 and the opening and closing of fixed scissors 8.

The frontmost portion of the movable scissors 7 and the fixed scissors 8 is provided with pointed jaws 11, and the jaws of the movable scissors 7 are retracted by 5-8 mm than the jaws of the fixed scissors 8, so that the movable scissors 7 and the fixed scissors 8 are overlapped when cutting. combine.

The facing surfaces of the pointed jaws 11 are provided with anti-slip lines.

Alternatively, use insulating olecranon pliers to transform into small garden scissors, that is, the scissor mouth part is insulated olecranon, and the handle of the scissors is a small flower and wood scissors handle, which not only ensures the safety of live operation, but also facilitates operation.
