The utility model, which is especially suitable for tighting for oxygen bags for fish in the open air, has the advantages of simple structure, small size, high durability and convenient operation and portability.

Description

Tension pliers for exygen bag rapid tighting for fish

The utility model relates to the hand tools of culture fishery and packaged or material, specifically a kind of tension pliers that is used for fry oxygen bag tying.

In culture fishery, often and in a large number use oxygenation bag transportation fry and fingerling, using sealing machine or heating of plastic to seal oxygen bag and be absolutely unsafe, all is to adopt rope yarn or rubber band binding tying at present, and this tying up generally all is manual operations, it ties up loaded down with trivial details, labour intensity is big, and work efficiency is low, and it is also inconvenient to separate bag, and often do not leak gas because of tying is firm, leaking causes the fry and fingerling survival rate to reduce; Use elastic tape to tie up oxygenation bag or existing various enlarging pincers or hand vice and open elastic tape and tie up,, and be difficult to or be unsuitable for the enlacement packaging of open-air oxygen bag because of the hand vice enlarging is strip or the enlarging caliper is long-pending big.

Task of the present utility model provides that a kind of volume is little, and enlarging is big, and is easy to carry, can be rapid and simple, and tying is solid and reliable and be particularly suitable for the tension pliers of the quick tying of oxygen bag for fish under the field condition.

The utility model is to be made of tong arm, push rod, chela, connecting rod, two tong arms flexibly connect relatively by connector, the forward part of push rod is installed respectively in the square groove of two tong arm inboards, the rear end of push rod is fixed on the ram seat, ram seat flexibly connects with two tong arms respectively by connecting rod, and chela is fixed on the front end of tong arm and push rod.

The utility model is simple in structure, volume is little, light durable, carry with easy to use, be specially adapted to carry out under the field condition tying packing of oxygen bag for fish.During use, the tong arm rear end is slightly pushed, chela magnifies, the rubber ring that is with on chela than strong elastic can be opened greatlyyer, rubber ring after will opening is inserted in the oxygen bag for fish sack that volume is pricked, and takes out chela more smoothly, has just finished the tying packing of an oxygen bag, and it is very firm, can not leak gas drainage, both saving of work and time, simple and fast is separated bag and also is very easy to again.The utility model also can be from the packaging industry that is widely used in objects such as food, health care, chemical industry and material as a kind of hand tools.

Further specify below in conjunction with accompanying drawing.

As shown in Figure 1,

tong arm

1 and 2 likeness in form fairings, their structure and shape size are identical, front end is fixed with chela 3 and 4 respectively, chela 3 and 4 and

tong arm

1 and 2 be good in vertical state, the inboard that is positioned at first half at

tong arm

1 and 2 all has square groove 9 and 10, respectively be embedded with pulley 11 and 12 at square groove 9 and 10 front ends, push rod 13 and 14 is set in square groove 9 and 10 by pulley 11 and 12 respectively, front end in push rod 13 and 14 is fixed with chela 5 and 6, chela 5 and 6 and push rod 13 and 14 plumbness be good, and with the chela 3 and 4 shapes of

tong arm

1 and 2 front ends, size matches (referring to Fig. 2, Fig. 3), tong arm 1 and the 2 relative flexible connections of passing through above it of connector 7 with 8, as rivet etc. (referring to Fig. 4), inboard at the latter half of

tong arm

1 and 2 is connected with connecting rod 15 and 16 respectively, and push rod 13 and 14 rear end are fixed on the connecting rod base 17 connecting rod base 17 and connecting rod 15 and 16 movable riveted joints.

When using the utility model, earlier with the high-strength rubber snare at chela 3,4,5, on 6,

tweezers arm

1 and 2 rear end again, connecting rod 5 and 16 moves backward, drivening rod seat 17 and push rod 13,14 motions backward, the chela 3 of push rod and tong arm front end, 4,5, the open-shaped attitude of 6 movement therewith, treat that elastic tape is extended when big, to be inserted in the rubber ring behind the off-the-shelf oxygen bag for fish sack volume bundle, unclamp stressed tong arm, chela 3,4,5,6 at push rod 13, close up under the elastic force effect that 14 stress deformations recover, extract chela out, rubber ring just securely hoop prick on the oxygen sack, easy to operation, the tying up of the oxygen bag for fish sack under the very suitable field condition.
