Abstract

An improved plier comprises two grab handles. A clamped part is arranged at one end of each grab handle. A pin joint is arranged between each grab handle and clamped part. A pinhole for a connecting pin is arranged at the center of each pin joint. An elastic body is arranged between two pin joints and two fixed end of the elastic body are fixed on two pin joints respectively. The utility model can ensure the automatic reset function of the pliers, which improves the practicability of the pliers greatly.

Description

Improved pliers

Technical field

The utility model relates to a kind of hand-operated tools, relate in particular to a kind of can automatically reset improved pliers.

Background technology

As shown in Figure 7, its be general common can automatically reset pliers, this pliers 6 is to be articulated mutually by two levers 61 to form, the front end of each lever 61 has an articulated section 62 respectively, articulates mutually for two levers 61, and each lever 61 extends a pincers portion 63 forward by this articulated section 62 respectively, set firmly a compression spring 64 between the relative inner of each lever 61 nearly these articulated section 62, elastic force by this compression spring 64 can automatically reset two levers 61 and opens, for reusing.

Because this compression spring 64 is to expose to 61 of two levers, therefore, cause this pliers to automatically reset, the difficulty in the increase use easily because of fixing bad or be out of shape or come off because of the external force effect.

Moreover, because of this compression spring 64 is to be arranged between the relative inner of two levers 61, and occupy the space of 61 of this levers, make 61 structures that other function can't be set again of two levers, and make the practicality of this pliers not good.

So, how to improve the automatically reset shortcoming of aforementioned existing hand-held tool, then be the improved emphasis of the utility model.

The utility model content

For overcome existing can be automatically reset the above-mentioned shortcoming that exists of pliers, the utility model provides a kind of improved pliers, the utility model can be guaranteed the effect that automatically resets of this pliers, improves its practicality greatly.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of improved pliers comprises two levers, and an end of each lever has a pincers portion respectively, has an articulated section respectively between each lever and pincers portion, articulates mutually for two levers, and the centre of each articulated section has a pivoted hole respectively, for the axostylus axostyle pivot joint that stretches through; It is characterized in that being provided with an elastomer between relative inside, described articulated section, this elastomer has two stiff ends, for being individually fixed in each articulated section.

Aforesaid improved pliers, wherein elastomer is the torque spring of an annular, and each articulated section opposed inside face is provided with the groove of an annular respectively around this pivoted hole, and this elastomer is to be placed in the space of involutory of each groove.

Aforesaid improved pliers, wherein elastomer is a compression spring, and each articulated section opposed inside face is provided with the groove of a semicircle respectively in a side of this pivoted hole, and this elastomer is placed in the space of each groove between being involutory.

Aforesaid improved pliers wherein is provided with an operate portions between the relative inner of the nearly articulated section of two levers.

Aforesaid improved pliers, wherein operate portions is the structure of a tube gripper, portion combines with electric wire for clamping terminal pipe.

The utility model can be guaranteed the effect that automatically resets of this pliers, improves its practicality greatly.

The specific embodiment

Seeing also Fig. 1 and Fig. 2, is the first selected example structure of the utility model shown in the figure.It has two levers 1, and an end of each lever 1 has a pincers portion 11 respectively, and each

lever

1 and 11 in this pincers portion have an articulated section 2 respectively, articulates mutually for two levers 1, and makes two levers 1 drive the opening and closing of two pincers portions 11, supplies the clamping workpiece.

The centre of each articulated section 2 has a pivoted hole 21 respectively, for an axostylus axostyle 22 pivot joint that stretches through, and each articulated section 2 opposed inside face is equipped with an annular groove 23 respectively around this pivoted hole 21, in the involutory space of each groove 23, for a ccontaining elastomer 24, in the present embodiment, this elastomer 24 is the torque spring of an annular, and this elastomer 24 has two stiff ends 241, as shown in Figure 3, and for being individually fixed in each articulated section 2.

Be provided with an operate portions 12 between the relative inner of above-mentioned two levers 1 nearly articulated section 2, in the present embodiment, this operate portions 12 is the structure of a tube gripper, and portion combines with electric wire with clamping terminal pipe.

Whereby, when gripping two levers 1 made 11 clampings of two pincers portions, this elastomer 24 was put aside elastic force because of two stiff ends 241 are individually fixed in each articulated section 2, after decontroling two levers 1, can two levers 1 be opened automatically reset, in order to reusing because of this elastomer 24 discharges elastic force.

Because this elastomer 24 is to be located in the groove 23 of two articulated sections, 2 relative inner, and is hidden in two articulated sections 2, and this elastomer 24 can in use not come off, and can guarantee the effect that automatically resets of this pliers.

Moreover, because of this elastomer 24 is to be located in two articulated sections 2, make the operate portions 12 that other function can be set between the relative inner of this two lever 1, improve the practicality of this pliers greatly.

See also Fig. 4 to shown in Figure 6, it is second embodiment of the present utility model, wherein, this elastomer 25 is a compression spring, each articulated section 2 opposed inside face is provided with the groove 26 of a semicircle respectively in a side of this pivoted hole 21, this elastomer 25 promptly is placed in the space of each groove 26 between being involutory, and the stiff end 251 of these elastomer 25 2 ends is individually fixed in each articulated section 2.

Whereby, when gripping two levers 1 made 11 clampings of two pincers portions, this elastomer 25 was compressed to accumulate elastic force because of two stiff ends 251 are individually fixed in this articulated section 2, after decontroling two levers 1, answer release elastic force because of this elastomer 25 opens two levers 1 automatically and resets, in order to reusing.
