Abstract

The utility model discloses pliers, which comprise two chucks, a positioning pin, two adjusting blocks, a spring and two handles. The two chucks are both provided with a positioning hole, the two positioning holes are matched mutually, and the sidewalls of the chucks are respectively provided with a through hole; the positioning pin is arranged in the two positioning holes; the two adjusting blocks are respectively arranged in the two through holes in a matching way; the spring is arranged between the sidewalls of the two chucks, and the two ends of the spring are respectively contacted with one end of the two adjusting blocks; and the two handles are respectively connected with one end of the chucks in a matching way. Due to the appropriate clamping force, the utility model can solve the problems that soft, hard or crisp materials can be damaged when being clamped and excessively small items can not be clamped firmly.

Description

Pliers

[technical field]

The utility model relates to a kind of pliers, and particularly a kind of adjustable clamp is held the pliers of 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 at 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.Now all kinds of on the market pliers shape size length sizes are all uneven, be not that each user can both find the suitable pliers that oneself uses, as be not the pliers length distance all be just in time, oversizely lack very much all inconvenient clamping, hand as 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 purpose of this utility model is to provide a kind of pliers, can avoid using some objects softer, harder or more crisp material of pliers clamping to damage the phenomenon that the too small object of phenomenon and some volumes of clamping can't firm grip by the chucking power of this pliers.

For achieving the above object, the utility model 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 handles, 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 utility model can avoid using some objects softer, harder or more crisp material of pliers clamping to damage the phenomenon that the too small object of phenomenon and some volumes of clamping can't firm grip.

For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[specific embodiment]

With reference to Figure 1 and Figure 2, pliers of the present utility model, 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 by riveted joint;

Two regulating blocks 13, it is located at respectively in above-mentioned two through holes 112, and the external screw thread 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 by stretching of regulating block 13;

Two handles 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 by 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 using some objects softer, harder or more crisp material of pliers clamping to 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 by 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

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

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

2. pliers as claimed in claim 1 is characterized in that the external screw thread that internal thread that above-mentioned through hole is provided with and regulating block are provided with cooperatively interacts.

3. pliers as claimed in claim 1 is characterized in that, passes through threaded engagement between above-mentioned handle and the chuck.
