Abstract

The invention relates to a cross-shaped clamp and a use method of the cross-shaped clamp. The cross-shaped clamp is characterized in that the cross-shaped clamp comprises four groups of pliers uniformly distributed around a circle; a handle part of each group of pliers is provided with a wedge mouth which is composed of two single clamps. A cross-shaped wedge is arranged in the wedge mouths of the four groups of pliers; a nut is in threaded connection with the tail end of the cross-shaped wedge; an electric hand drill drives the nut to rotate; and the wedge mouth is opened in a spreading manner, and jaws of the four groups of pliers are folded at the same time to tightly clamp a cross clip of an invisible protective window. The cross-shaped clamp provided by the invention has the beneficial effect that the work efficiency is doubled compared with the prior art.

Description

Cross-shaped clamp and using method thereof

Technical field

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

Background technology

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

If but pressed from both sides, just cross clamp can be clamped on finer wire in length and breadth, so work efficiency could also improve.But also there is no such pliers so far.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, as long as the object of the invention is will provide a kind of folder once, just cross clamp can be clamped in the instrument on 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, under the driving of electric hand drill, once clamps cross clamp simultaneously.

Concrete technical scheme of the present invention is: it comprises four groups of circumferentially uniform pliers, has gap between pliers; Often organize pliers to form with the list pincers that pin is hinged by two, and between the head of single pincers, jaw is set, and be provided with the Compress Spring that struts jaw; The shank often organizing pliers has one and singly clamps by two the wedge mouth formed, and a cruciform wedge is arranged in the wedge mouth of four groups of pliers, and can move in four of a sleeve groove; One nut is connected with the tailing screw flight of cruciform wedge, and one end of nut is provided with a shank be connected with electric hand drill; Above-mentioned part is placed in a sleeve, and the pin often organizing pliers inserts in the locating hole of sleeve, and is screwed;

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

One internal circlip is located in the circlip groove of sleeve;

The using method of said mechanism: electric hand drill drive nut rotates, and by screw-driven, cruciform wedge is moved in the groove of sleeve; When cruciform wedge moves towards pin, wedge mouth is softened, then the elastic force that the jaw of four groups of pliers overcomes Compress Spring simultaneously closes up, clamping cross clamp; Otherwise when cruciform wedge moves from pin, wedge mouth reduces, and Compress Spring forces jaw to strut.

Usefulness of the present invention is:

Work efficiency doubles than prior art.

Detailed description of the invention

The present invention includes four groups of circumferentially uniform pliers 1(and see Fig. 7), there is between pliers gap 2; Often organize pliers and form (see figure 10) by two with the list pincers 4 that pin 3 is hinged, and between the head of single pincers, jaw 5 is set, and be provided with the Compress Spring 6 that struts jaw; The shank often organizing pliers has wedge mouth 7, cruciform wedge 8 be made up of two single pincers 4 and is arranged in the wedge mouth 7 of four groups of pliers, and can move (see Figure 11) in four of sleeve 11 groove 15; One nut 9 is connected with the tailing screw flight of cruciform wedge, and one end of nut is provided with a shank 10 be connected with electric hand drill 16; Above-mentioned part is placed in sleeve 11, and the pin often organizing pliers inserts in the locating hole 12 of sleeve, and fixes (see figure 6) with screw 13.

The shank of four groups of pliers is by turn 14 envelope.

One internal circlip 17 is stuck in the circlip groove 18 of sleeve 11, to stop nut 9 axial float.

Method of operating of the present invention: the shank 10 of the chuck clamping screw nut of electric hand drill, the chuck drive nut of forward or reverse electric hand drill rotates, and by screw-driven, cruciform wedge 8 is moved in four grooves 15 of sleeve 11.When cruciform wedge moves towards pin 3, wedge mouth 7 is softened, then the elastic force that the jaw 5 of four groups of pliers overcomes Compress Spring 6 simultaneously closes up, clamping cross clamp 20; Otherwise when cruciform wedge moves from pin 3, wedge mouth 7 reduces, Compress Spring 6 forces jaw 5 to strut, easily to entangle next cross clamp.

Claims

1. a using method for cross-shaped clamp, is characterized in that this cross-shaped clamp comprises four groups of circumferentially uniform pliers, has gap between pliers; Often organize pliers to form with the list pincers that pin is hinged by two, and between the head of single pincers, jaw is set, and be provided with the Compress Spring that struts jaw; The shank often organizing pliers has one and singly clamps by two the wedge mouth formed, and a cruciform wedge is arranged in the wedge mouth of four groups of pliers, and can move in four of a sleeve groove; One nut is connected with the tailing screw flight of cruciform wedge, and one end of nut is provided with a shank be connected with electric hand drill; Four groups of pliers, pin, Compress Spring, cruciform wedge and nuts are placed in sleeve, and the pin often organizing pliers inserts in the locating hole of sleeve, and is screwed;

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