Abstract

The invention discloses a pair of box-opening tool tongue buckle pliers for a protection screen packing box. Thin steel sheets are respectively welded to opposite parts of an upper pliers nozzle and a lower pliers nozzle which can be in contact with each other to form a flat pliers nozzle, and an inverted downward hook is welded to the outer side of the front end of the upper pliers nozzle close to the thin steel sheets. By utilizing the inverted downward hook, a constructor can pry a tongue-shaped lock catch towards the outer side simply accurately safely rapidly in a labor saving mode; simultaneously, the tongue-shaped lock catch can be bent flatly conveniently upwards through the flat pliers nozzle, the foundation is laid well for further prying the packing box, and not only is working efficiency improved, but also personal safety in the removal process can be guaranteed.

Description

Protection screen packing case box opening tool tongue clasp forceps

Technical field

The present invention relates to a kind of box opening tool tongue clasp forceps, particularly relate to a kind of box opening tool tongue clasp forceps that can remove efficiently, efficiently protection screen packing case.

Background technology

In the engineerings such as newly-built, technological transformation of power industry, use in a large number and change protection screen, and protection screen belongs to precision apparatus instrument, in its transportation, handling process, all adopt good external packing to protect, with anti-tamper.Most of producer is as auspicious in south, glued board extranal packing box is all used in south certainly, adopts the mode of tongue type snap close to fix and airtight casing.Tongue type snap close has the feature of firm folding, good airproof performance, there is no at present the specific purpose tool of removing snap close.

At present, when removing with the fixing packing case of tongue type snap close, workmen's general using screwdriver with through tang slowly levers up along the edge of tongue type snap close, then with pliers or hammer, the tongue type snap close levering up is revised to cut-off.This way not only operates inconvenience, and very easily there is screwdriver slip phenomenon, scratch the personal safety hidden danger such as hand, and affect operating efficiency, when with pliers or hammer cut-off, the distortion meeting of tongue type snap close is more serious in addition, and this glued board of prying open for next step has very large resistance.

Summary of the invention

The deficiency and the potential safety hazard that exist when overcoming the tongue type snap close of existing dismounting protection screen packing case; the invention provides a kind of protection screen packing case box opening tool tongue clasp forceps; use the tongue type snap close that this tongue clasp forceps can comparatively convenient, fast dismounting protection screen packing case, in demolishing process, ensure personal safety simultaneously.

The present invention solves the problems of the technologies described above the technical scheme adopting to be:

A kind of protection screen packing case box opening tool tongue clasp forceps, comprise upper clamp nozzle, upper tong arm, lower tong arm, lower clamp nozzle, the rear end of upper clamp nozzle connects the front end of upper tong arm, one side of the rear end of lower clamp nozzle is connected to the front end of tong arm, the opposite side of the rear end of lower clamp nozzle is connected to the front end of lower tong arm, upper tong arm middle part and lower tong arm middle part all have relative inside arc surface, interior one end that connects connecting rod of arc surface that lower tong arm middle part is inside, the other end of connecting rod is arranged in the inside arc surface in tong arm middle part, the bolt being threaded with the rear end of upper tong arm props up one end of the connecting rod in upper tong arm, one end of the rear end spring of lower clamp nozzle, the other end of spring connects the inner side, middle part of upper tong arm, the relative position that upper clamp nozzle can contact with lower clamp nozzle front end is welded with respectively stalloy and forms flat-shaped jaw.

Further, the area of described stalloy is 3-5cm ².

Further, on upper clamp nozzle near near the type crotch that falls down of the front end outside welding one stalloy.

Further, described in the fall down crooked certain angle of crotch of type crotch, make crotch point to upper tong arm axis direction.

The invention has the beneficial effects as follows, by the type crotch that falls down, workmen comparatively labour-saving levers up tongue type snap close laterally, simply accurate, safe and efficient; Meanwhile, utilize flat-shaped jaw to make progress easily curved directly by tongue type snap close is smooth, pry open packing case lay a solid foundation for next step, this not only increases work efficiency and also guarantees the personal safety in demolishing process.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of locking pliers in prior art.

Fig. 2 is the schematic diagram of the tongue clasp forceps of first embodiment of the invention.

Fig. 3 is the schematic diagram of the tongue clasp forceps of second embodiment of the invention.

Fig. 4 is the partial enlarged drawing of the tongue clasp forceps of second embodiment of the invention.

In figure, each component names is as follows:

1-upper clamp nozzle, the upper tong arm of 2-, 3-bolt, 4-connecting rod, tong arm under 5-, 6-spring, 7-lower clamp nozzle, 8-stalloy, 9-stalloy, the 10-type crotch that falls down

The specific embodiment

Below in conjunction with accompanying drawing, describe the present invention.

With reference to Fig. 2, the tongue clasp forceps of first embodiment of the invention comprises upper clamp nozzle 1, upper tong arm 2, lower tong arm 5, lower clamp nozzle 7, the rear end of upper clamp nozzle 1 connects the front end of upper tong arm 2, one side of the rear end of lower clamp nozzle 7 is connected to the front end of tong arm 2, the opposite side of the rear end of lower clamp nozzle 7 is connected to the front end of lower tong arm 5, upper tong arm 2 middle parts and lower tong arm 5 middle parts all have relative inside arc surface, interior one end that connects connecting rod 4 of arc surface that lower tong arm 5 middle parts are inside, the other end of connecting rod 4 is arranged in the inside arc surface in tong arm 2 middle parts, the bolt 3 being threaded with the rear end of upper tong arm 2 props up one end of the connecting rod 4 in upper tong arm 2, one end of the rear end linking springs 6 of lower clamp nozzle 7, the other end of spring 6 connects the inner side, middle part of upper tong arm 2, upper clamp nozzle 1 is welded with respectively stalloy 8 with the relative position that lower clamp nozzle 7 front ends can contact, 9 form flat-shaped jaw, during to pincers, can dock by smooth joint close, clamp together up and down consistent.

With reference to Fig. 3-4, the tongue clasp forceps of second embodiment of the invention is on the basis of first embodiment, to have done further improvement.The tongue clasp forceps of second embodiment is near near the type crotch 10 that falls down of the front end outside welding one stalloy 9 on upper clamp nozzle 1, and the crooked certain angle of crotch of the type that falls down crotch 10, makes crotch point to above tong arm 2 axis directions.

When removing the tongue type snap close of protection screen packing case; workmen utilizes type crotch 10 that tongue type snap close is levered up laterally; and then utilize flat-shaped jaw to clamp the tongue type snap close having been levered up by the type crotch 10 that falls down, by tongue type snap close lever up part smooth make progress easily curved straight.Utilize crotch can lever up simply accurately tongue type snap close, flat-shaped jaw, in the process of curved straight tongue type snap close that makes progress, guarantees that tongue type snap close is not yielding, and strained tongue type snap close is pressed and also can be made it smooth, vertical by the pincers of flat-shaped jaw.

Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
