Abstract

Disclosed is water pipe scissors with balanced structure. A left group connection column and a right group connection column are convexly arranged on the two sides of a stationary jaw, a neck which is used for blocking and buttoning a retaining ring is circumferentially arranged on the near ends of the group connection columns, left-and-right balanced support blocks are sleeved on the group connection columns and are limited by the retaining ring to be blocked and buttoned, the top face of the left-and-right balanced support blocks is roughly of a 'L' shape, the bottom support face of the support blocks is engaged with a support face of the stationary jaw, forming a concave curved shape, and a tip edge is arranged on the bottom support face. By using the extension of the balanced support block, the length of the bottom portion of the axial support face can be largely increased when the water pipe is cut, thereby improving the balance and stability of the water pipe location and achieving the tangent plane quality of good flatness and accuracy.

Description

Water pipe with balanced structure is cut

Technical field

The utility model relates to water pipe to be cut, and especially a kind of water pipe with balanced structure is cut.

Background technology

It is a kind of in order to shear the hand-held tool of plastic cement tubing that water pipe is cut, the water pipe of commonly using is cut, as shown in Figure 1, its body is by son, female handle body 01,02 front end is organized respectively and is provided with fixed jaw 03 and movable jaw 04 composition, a proper and default tension clearance 05 contraposition of fixed jaw 03 central authorities of the blade side of its movable jaw 04, when cutting off water pipe 06, this movable jaw 04 can insert in the tension clearance 05, but fixed jaw 03 has one wide feed pipe 06 breasting (referring to shown in Figure 2) when being cut in tension clearance 05 both sides places: because this fixed jaw 03 position generally is to cast with female handle body 02 base material one, about the generally only about 2cm of its Rational Thickness, firm breasting area when being not sufficient to provide water pipe 06 to be cut, therefore, when shearing water pipe 06, often produce the slippage of water pipe deflection and cause shear surface 07 crooked, cause the excessive phenomenon of error (shown in the angle X among Fig. 2 °), the scarce fraud of this kind makes this water pipe cut when running into the higher working environment of precision requirement, obviously loses its practicality and truly has necessity of improvement.

Summary of the invention

In view of this, main purpose of the present utility model provides and a kind ofly is provided with left and right balance in fixed jaw both sides expansion group and holds piece so that water pipe when being cut polarization balance is firm more, the water pipe with balanced structure that the tangent plane glacing flatness is better is cut.

The technical scheme that the utility model adopted: a kind of water pipe with balanced structure is cut, and this water pipe is cut body and mainly comprised sub-handle body, female handle body, fixed jaw and movable jaw; It is characterized in that: these fixed jaw both sides convex with left and right winding post relatively, this winding post proximal end is equipped with the draw-in groove for the clasp buckle, and left and right balance is held piece and is provided with the axis hole that is linked on the winding post, and it is fixed with spacing group of clasp buckle, wherein: this left and right balance is held the piece end face and slightly is one " L " bearing surface shape, its bottom bearing surface cooperates the bearing surface of fixed jaw to be a concave arc shape, and is provided with tip edge.

Wherein: this left side, right balance holds that piece holds piece by an end respectively and a backstop is formed, piece is held at the end and backstop winding place is provided with the involutory axis hole of overlaid, be inserted in regular turn on the winding post of fixed jaw, and it is fixed with spacing group of clasp buckle, cover is organized a torque spring on the winding post again, the inboard of backstop axis hole is provided with a groove, just can insert for this torque spring, the rear side of this groove forms a groove, just can embed for protruding out end behind the torque spring, the front side tool one of this groove allows mouth, protrudes out end before the torque spring and just can pass and be embedded in the end and hold in the inboard default groove of piece, and hold between the bottom side of piece and combined of backstop and is separated with a spacing mutually at the end again; In addition, this backstop inboard also is provided with the slotted eye of a central tool projection, and this projection cover is organized a spring, and this projection just plugs together mutually to being combined in the set slotted eye of fixed jaw.This spring is then shored between backstop and fixed jaw.

Effect of the present utility model, advantage are as follows:

1, the utility model holds piece owing to set up left and right balance in the fixed jaw both sides, so receiving area (can increase the axial bearing surface length of water pipe of 2-3cm at least again) of bottom in the time of can significantly increasing water pipe and cut, therefore can reduce the possibility of water pipe deflection slippage, really improve the balance steadiness of its location, and then can obtain glacing flatness, the preferable tangent plane quality of precision.

2, the utility model holds the concave arc shape areal of support that has tip edge on the piece end of owing to, and cooperates the inclined plane design of backstop, produces on-slip when water pipe is cut and reaches the effect and the advantage of putting middle location automatically.

3, piece is held and backstop has the characteristic of elasticity opening and closing in the end of the present utility model, holds contacting of piece with balance when water pipe is cut and keeps a compact state.

4, the utility model is by the structural design of shoring spring mutually between its backstop and fixed jaw, reaches to eliminate this two fit clearance, make the tightr, more firm of its combination.
