Abstract

The invention discloses pinchers which comprise two chucks, location pins, two regulation blocks, a spring and two handles, wherein each chuck is provided with a location hole, the two location holes are mutually matched, the side walls of the chucks are respectively provided with a through hole; the location pins are arranged in the two location holes; the two regulation blocks are respectively positioned in the two through holes and matched with the through holes; the spring is arranged between the side walls of the two chucks, two ends of the spring are respectively contacted with one ends of the two regulation blocks; and the two handles are respectively connected and matched with one ends of the chucks. The clamping force of the pinchers can avoid damage caused by clamping softer, harder or softer objects with the pinchers and incapability of firmly clamping objects with smaller volume.

Description

Pliers

[technical field]

The present invention relates to a kind of pliers, particularly a kind of pliers of scalable clamping power size.

[background technology]

Because existing pliers varieties and functions is all more single; The holding function limitation is bigger; Can't can both reach the management and control of good chucking power to each object; If use existing grip to have the pliers of spring: 1, clamping some, behind the object of harder or more crisp material, the excessive bad phenomenon that is easy to generate areal deformation and damaged surfaces of chucking power; 2, some volumes of clamping are crossed small object, chucking power is too small usually can produce can't firm grip phenomenon.Existing all kinds of on the market pliers shape size length sizes are all uneven; Be not that each user can both find the pliers that is fit to own use, as be not the pliers length distance all be just in time, oversizely lack very much all inconvenient clamping; Hand like the people is not of uniform size; Make the long weak point that has that has that the handle hold pliers becomes, if more loaded down with trivial details during long uses, if during too short uses very inconvenience cause use to require great effort; And for example some special objects of clamping (routine high temperature corrodes the volatile human injury that causes) need staff that special article is kept one section safe distance, and oversize inconvenient clamping is used, and too weak point damages people's cognition.

[summary of the invention]

In view of this; The object of the present invention is to provide a kind of pliers, the chucking power through this pliers can avoid the use of some objects softer, harder or more crisp material of pliers clamping and damage the phenomenon that the too small object of phenomenon and some volumes of clamping can't firm grip.

For achieving the above object, the present invention provides a kind of pliers, and it comprises:

Two chucks are equipped with locating hole on each chuck, and two locating holes cooperatively interact, and also are respectively equipped with through hole on the sidewall of this chuck;

Alignment pin, it is provided with in above-mentioned two locating holes;

Two regulating blocks, it is located at respectively in above-mentioned two through holes, and matches with it;

Spring, it is located between the sidewall of above-mentioned two chucks, and two ends contact an end of above-mentioned two regulating blocks respectively;

Two grip, it is connected cooperation with an end of above-mentioned chuck respectively.

Especially, the external screw thread that is provided with of the internal thread that is provided with of above-mentioned through hole and regulating block cooperatively interacts.

Especially, pass through threaded engagement between above-mentioned handle and the chuck.

Compared to prior art, the chucking power of pliers of the present invention can avoid the use of some objects softer, harder or more crisp material of pliers clamping and damage the phenomenon that the too small object of phenomenon and some volumes of clamping can't firm grip.

For the object of the invention, structural feature and function thereof are had further understanding, conjunction with figs. specifies as follows now:

[specific embodiment]

With reference to Fig. 1 and shown in Figure 2, pliers of the present invention, it comprises:.

Two chucks 11 are equipped with 111, two locating holes 111 of locating hole and cooperatively interact on each chuck 11, also be respectively equipped with through hole 112 on the sidewall of this chuck 11, and in present embodiment, this through hole 112 is provided with internal thread;

Alignment pin 12, it is provided with in above-mentioned two locating holes 111, and this alignment pin 12 can wait other modes to match with locating hole 111 through riveted joint;

Two regulating blocks 13, it is located at respectively in above-mentioned two through holes 112, and the external screw thread that which is provided with matches with the internal thread of through hole 112, thereby regulates collapsing length;

Spring 14, it is located between the sidewall of above-mentioned two chucks 11, and this spring 14 contacts with an end of above-mentioned regulating block 13, and controls the size of its elastic force through stretching of regulating block 13;

Two grip 15, it is connected cooperation with an end of above-mentioned chuck 11 respectively, in preferred embodiment, between the end of this handle 15 and chuck 11 through threaded engagement, and the length that combines of this mode adjustable handle grip 15 and chuck 11.

In present embodiment; This pliers has following effect: 1, rotate the elastic force that both sides regulating block 13 comes regulating spring; Thereby regulate the chucking power size of pliers chuck 11; And then avoid the use of some objects softer, harder or more crisp material of pliers clamping and damage phenomenon, avoid some volumes of clamping to cross the phenomenon that small object can't firm grip; 2, can regulate the length of handle 15 through the screw thread on the pliers handle 15, make each user can both find suitable use length to come the suitable object of clamping through overregulating.

Claims (3)

1. a pliers is characterized in that, this pliers comprises:
