The specific embodiment

This use is novel to provide a kind of pliers, comprise right handles 5, left handle 4, with last vice body 1 that is connected with right handles 5 and the following vice body 2 that is connected with left handle 4, last vice body 1 intersects with following vice body 2 and is connected by connectors such as pin or nail pivot, being connected of right handles 5 adjustable lengths with last vice body 1, being connected of left handle 4 adjustable lengths with following vice body 2.Vice body can be connected by the mode of clamping with handle, also can connect herein by the mode of spin locking not limit.Below in conjunction with accompanying drawing, be described in detail by a locking piece ways of connecting with vice body and handle.

Please refer to Fig. 1, last vice body 1 front end comprises upper grip head 11, and the rear end comprises tong arm 12; Following vice body 2 front ends comprise lower pliers head 21, and the rear end comprises tong arm 22 down.Upper grip head 11 and lower pliers head 21 intersect to form the jaw that is used for gripping objects; Middle part at last vice body 11 and following vice body 21 is provided with an aperture respectively, injects aperture by pin 3 and makes vice body 1 be connected with following vice body 2 pivots.

Please refer to Fig. 2 and Fig. 3, last tong arm 12 comprises the cross sectional dimensions of the size of first through hole, 122, the first through holes 122 greater than right handles 5.In the utility model, first through hole 122 is a rectangle, and the cross section of right handles 5 is for also being rectangle, and the length and width of first through hole 122 are greater than the length of right handles 5 and wide.Last tong arm 12 comprises that also first locking piece, 121, the first locking pieces 121 are arranged on the upper end/lower end of first through hole 122.Right handles 5 can be slided in first through hole 122, by first locking piece 121 right handles 5 is locked.When unclamping first locking piece 121, first locking piece 121 separates with right handles 5, and right handles 5 can be slided in first through hole 122 and be regulated the length of right handles 5, and then regulates the arm of force of right handles 5; When tightening first locking piece 121, first locking piece 121 pushes against right handles 5, and right handles 5 just is fixed in first through hole 122, and right handles 5 is locked.

The syndeton of last vice body 1 and right handles 5, vice body 2 is identical with the syndeton of left handle 4 down together, promptly descends tong arm 22 to comprise the cross sectional dimensions of the size of second through hole, 222, the second through holes 222 greater than left handle 4.In the utility model, second through hole 222 is a rectangle, and the cross section of left handle 4 is for also being rectangle, and the length and width of second through hole 222 are greater than the length of left handle 4 and wide.Following tong arm 22 comprises that also second locking piece, 221, the second locking pieces 221 are arranged on the upper end/lower end of second through hole 222.Left handle 4 can slide in second through hole 222, by second locking piece 222 left handle 4 is locked.When unclamping second locking piece 221, second locking piece 221 separates with left handle 4, the length that left handle 4 can slide and regulate left handle 4 in second through hole 222, and then the arm of force of adjusting left handle 4; When tightening second locking piece 221, second locking piece 221 pushes against left handle 4, and left handle 4 just is fixed in second through hole 222, and left handle 4 is locked.

In the present embodiment, left handle 4 and right handles 5 are the steel plate handle, and first locking piece 121 and second locking piece 221 are lock screw.

Handle 4 later half ends also coat one deck left side plastic cement handle 7 leftward, and the cross sectional dimensions of left plastic cement handle 7 is greater than the size of second through hole 222; Also coat the right plastic cement handle 6 of one deck at right handles 5 later half ends, the cross sectional dimensions of right plastic cement handle 6 is greater than the size of first through hole 122.Have anti-skidding line on left side plastic cement handle 7 and the right plastic cement handle 6, prevent that staff from sliding.In the present embodiment, the cross sectional dimensions of left handle 4 is less than the cross sectional dimensions of second through hole 222, the cross sectional dimensions of left side plastic cement handle 7 is greater than the size of second through hole 222, the purpose of this structure is, pliers in use, the front half-end of guaranteeing left handle 4 can slide in second through hole 222 to regulate left handle 4 length, guarantees that again the later half end of left handle 4 is in second through hole, 222 outsides, prevents that staff from squeezing wound.In like manner, the cross sectional dimensions of right handles 5 is less than the cross sectional dimensions of first through hole 122, the cross sectional dimensions of right plastic cement handle 6 is greater than the size of first through hole 122, the purpose of this structure is, pliers in use, the front half-end of guaranteeing right handles 5 can slide in first through hole 122 to regulate right handles 5 length, guarantees that again the later half end of right handles 5 is in first through hole, 122 outsides, prevents that staff from squeezing wound.

The utility model is normally regulated the length of left handle 4 and right handles 5 in use simultaneously.

Please refer to figure, 4, when clamping minor diameter object, therefore leicht fallen D/A can reduce the arm of force, shortens decreased food, and convenient the use is so withdraw handle; Carrying, use and depositing of pliers also is convenient in the handle withdrawal; Please refer to Fig. 5, when clamping major diameter or big article, need to use more energetically, at this moment, can reach the labour-saving effect by swelled handle length to increase the arm of force.

More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
