Abstract

The invention relates to a pair of manual cross clamp pliers for machining an invisible protection window. The manual cross clamp pliers comprise four groups of pliers uniformly distributed around the circumference, wherein the handle part of each group of pliers is provided with a wedge mouth comprising two single pliers; cross wedges are arranged in the wedge mouths of the four groups of pliers; the parts are arranged in a sleeve, a pin of each group of pliers is inserted into a positioning hole of the sleeve and fixed by a bolt; the tail part of each cross wedge is in hinged connection with a lever which is in hinged connection with a handle fixed on the sleeve; and a second compression spring is arranged between the lower part of the lever and the lower part of the handle. The use method comprises the steps as follows: a hand grasps the lower part of each lever and the lower part of the handle, the upper part of the lever pushes the cross wedge, the wedge mouth is opened, jaws of the four groups of pliers are retracted simultaneously, and cross clamps of the invisible protection window are clamped. The pair of manual cross clamp pliers for machining the invisible protection window has the benefit that the work efficiency is doubled compared with the prior art.

Description

The manual cross clamp of processing stealth protection window

Technical field

The present invention particularly relates to a kind of pliers of processing stealth protection window about a kind of instrument.

Background technology

At present, child's high building event of falling down from the building happens occasionally.For this reason, on the window of many high residential buildings the stealth protection window (see figure 1) has been installed.In order not influence people's visual effect, it mainly is made of very thin steel wire longitudinally, reinforces with one to two horizontal finer wire simultaneously, and steel wire gets out outside window in case child struts longitudinally.The finer wire of vertical and horizontal is fixed with a kind of Fig. 2, the cross clamp 20 with the iron sheet making shown in Figure 3.Fixedly add man-hour at cross clamp, cross clamp is clamped on the finer wire by the haircut direction shown in Fig. 3 with pliers usually, need longitudinal direction folder twice like this, horizontal direction folder twice, totally four times, cross clamp could be clamped on the finer wire in length and breadth some trouble of processing method.Afterwards, the someone had invented the pliers of two jaws, like this, as long as vertically press from both sides, laterally pressed from both sides, totally twice, just cross clamp can be clamped on the finer wire in length and breadth.Work efficiency is doubled.

If but press from both sides, just cross clamp can be clamped on the finer wire in length and breadth, work efficiency can also improve so.But also there is not such pliers so far.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the objective of the invention is to provide a kind of as long as folder once, just can be clamped in cross clamp the instrument on the finer wire in length and breadth.

Main technological route of the present invention is: the present invention is made up of four groups of pliers, once clamps cross clamp simultaneously.

Concrete technical scheme of the present invention is: it comprises four groups of pliers around circumference uniform distribution, has the gap between the pliers; Every group of pliers constitutes with the hinged list pincers of pin by two, and between the head of single pincers jaw is set, and is provided with first a compression spring that struts jaw; The shank of every group of pliers has a wedge mouth that is made of two single pincers, and a cruciform wedge is arranged in the wedge mouth of four groups of pliers, and can move in four grooves of sleeve; Above-mentioned part places in the sleeve, and the pin of every group of pliers inserts in the locating hole of sleeve, and is screwed; The afterbody of cruciform wedge and a lever are hinged, and this lever is hinged with the handle that is fixed on the sleeve; One second compression spring is set between the bottom of the bottom of described lever and handle;

The shank of four groups of pliers is by a turn envelope;

The using method of said mechanism: hold the bottom of tight lever and the bottom of handle, both spacings are dwindled, the second compression spring is compressed, the top of lever promotes cruciform wedge and moves towards pin in the groove of sleeve, the wedge mouth is strutted, then the jaw of the four groups of pliers elastic force that overcomes the first compression spring simultaneously closes up, and clamps cross clamp; Otherwise when the openhanded bottom of lever and the bottom of handle of opening, the elastic force of the second compression spring struts lever and handle bottom, makes both pitch enlargement, and cruciform wedge moves from pin, and the wedge mouth dwindles, and the first compression spring forces jaw to strut.

Usefulness of the present invention is:

Work efficiency doubles than prior art.

The specific embodiment

Four groups of pliers 1(that the present invention includes around circumference uniform distribution see Fig. 8), have gap 2 between the pliers; Every group of pliers constitutes (seeing Figure 11) by two with pin 3 hinged single pincers 4, and between the head of single pincers jaw 5 is set, and is provided with first a compression spring 6 that struts jaw; The shank of every group of pliers has one and is arranged in the wedge mouth 7 of four groups of pliers by two the single pincers 4 wedge mouths that constitute 7, one cruciform wedges 8, and can move (seeing Figure 12) in four grooves 15 of sleeve 11; Above-mentioned part places in the sleeve 11, and the pin of every group of pliers inserts in the locating hole 12 of sleeve, and with the fixing (see figure 6) of screw 13; The afterbody of cruciform wedge 8 and a lever 20 hinged (see figure 9)s, this lever 20 is hinged with the handle 21 that is fixed on the sleeve; The second compression spring 22 is set between the bottom of the bottom of described lever 20 and handle 21;

The shank of four groups of pliers is by a turn 14 envelopes;

The using method of said mechanism: hold the bottom of tight lever 20 and the bottom of handle 21, both spacings are dwindled, the second compression spring 22 is compressed, the top of lever 20 promotes

cruciform wedge

8 and 15 move (seeing Figure 11) towards pin 3 in the groove of sleeve, wedge mouth 7 is strutted, then the jaw 5 of the four groups of pliers elastic force that overcomes the first compression spring 6 simultaneously closes up, and clamps cross clamp; Otherwise, when the openhanded bottom of lever 20 and the bottom of handle 21 of opening, the elastic force of the second compression spring 22 struts lever 20 and handle 21 bottoms, make both pitch enlargement, cruciform wedge 8 moves from pin 3, wedge mouth 7 dwindles, and the first compression spring 6 forces jaw 5 to strut, in order to entangle next cross clamp easily.
