Abstract

The utility model relates to an opening adjustable clamping device capable of clamping objects with larger sizes, which is provided with a left handle (1) and a right handle (5) which are combined by a pivot shaft (6), wherein a left clamping seat (11) is fixedly connected to the left handle, and a left clamping head (2) is connected with the upper end of the left clamping seat; a torsional spring (7) is sheathed on the pivot shaft, wherein both expanding arms of the torsional spring (7) are respectively abutted on the inner sides of the left handle and the right handle; an adjusting arm (51) is fixedly connected to the right handle, a right clamping seat (4) is sheathed on the adjusting arm, and a right clamping head (3) is connected with the upper end of the right clamping seat. The utility model is suitable for clamping objects manually.

Description

The opening flexible jig

Technical field

The utility model relates to the utensil of gripping objects.

Background technology

A kind of hand vice formula anchor clamps in the prior art, on the pivot that left and right handle pivotly joins, be with torsion spring, torsion spring two is stretched one's arms and is resisted against left and right handle inboard, after singlehanded grip pressure left hand and right hand spindle clamp tool opens gripping objects, loosen hand support grip pressure power, anchor clamps are clamping article naturally, so this anchor clamps are not only agile but also easy to use.But, the opening degree of this anchor clamps is less, can not the larger-size object of clamping.

Summary of the invention

It is little that the utility model will solve existing hand vice formula anchor clamps opening degree, can not the clamping size than the problem of big article, a kind of opening flexible jig of the present utility model is provided for this reason, and the existing hand vice formula anchor clamps of the opening degree of this chucking opening increase considerably, can the clamping size than big article.

For addressing the above problem, the technical solution adopted in the utility model is left handle and the right handles that has through the pivot combination, be fixedly connected with its upper end of left holder on the left handle and be associated with left chuck, be with torsion spring on the pivot, two of torsion spring is stretched one's arms and is resisted against left handle and right handles inboard respectively, its special character is to be fixedly connected with regulating arm on the described right handles, is with its upper end of right holder on the regulating arm and is associated with right chuck.

Described regulating arm tilts extraterrestrial to extension in the right handles lateral.Described right holder is placed in regulating arm, can move according to regulating arm, moves inward closing when right handles, right holder and symmetry corresponding with left holder.After right holder moved a distance outward according to regulating arm, the opening degree of anchor clamps increased.

Turn round to clamping force though have between right holder and the regulating arm behind the gripping objects, right holder relative adjustment arm can not move again, thereby clamping article, in order to increase this clamping force, with the top making and settlement of described regulating arm is that concavo-convex alternate toothed surface is more suitable, corresponding therewith, right holder also makes into toothed surface with the position of regulating arm toothed surface combination.This toothed surface when gripping objects not, does not hinder right holder to move according to regulating arm.

Left and right holder left and right chuck that the upper end joins, holder end pivot relatively, left and right chuck is parallel with object surface in the time of can keeping gripping objects naturally like this.

Can be combined with the applying piece at described left handle and right handles lateral surface, the applying piece can be made by certain flexible material of tool such as rubber-plastics material, and its lateral surface camber so has excellent handle.

The utility model is owing to be fixedly connected with regulating arm on right handles, be with right holder on the regulating arm, when right holder move outside according to regulating arm one apart from the time, the opening degree of anchor clamps increases, so but the larger-size object of the utility model clamping, the existing clip-like of its clamping applicability increases substantially.

Fig. 3 is that the right holder of the utility model moves a distance back gripping objects schematic diagram outward.

The specific embodiment

The opening flexible jig, have left handle 1 and right handles 5 through pivot 6 combinations, be fixedly connected with left holder 11 its upper ends on the left handle and be associated with left chuck 2, be with torsion spring 7 on the pivot, two of torsion spring 7 is stretched one's arms and is resisted against left handle and right handles inboard respectively, be fixedly connected with regulating arm 51 on the right handles, be with right holder 4 its upper ends on the regulating arm and be associated with right chuck 3.Above the regulating arm 51 is concavo-convex alternate toothed surface.Left handle and right handles lateral surface are combined with the applying piece 8 that rubber-plastics material is made.

Claims

1, opening flexible jig, have left handle (1) and right handles (5) through pivot (6) combination, be fixedly connected with its upper end of left holder (11) on the left handle and be associated with left chuck (2), be with torsion spring (7) on the pivot, two of torsion spring (7) is stretched one's arms and is resisted against left handle and right handles inboard respectively, it is characterized in that being fixedly connected with regulating arm (51) on the described right handles, be with its upper end of right holder (4) on the regulating arm and be associated with right chuck (3).

2, anchor clamps as claimed in claim 1 is characterized in that being above the regulating arm (51) concavo-convex alternate toothed surface.

3, anchor clamps as claimed in claim 1 or 2 is characterized in that described left handle and right handles lateral surface are combined with applying piece (8).
