Abstract

The utility model discloses a pair of labor-saving pliers of saving more labor when in use. The labor-saving pliers comprise a left handle and a right handle, wherein a left pliers head is fixedly arranged at the upper end of the left handle; a sliding rod and a positioning hole are formed at the upper end of the right handle respectively; the sliding rod is arranged in a sliding slot at the lower end of a right pliers head in a sliding manner; a positioning bolt matched with the positioning hole is arranged at the upper end of the left handle; the positioning bolt is arranged in the positioning hole in a sliding manner; the left pliers head and the right pliers head are provided with a left installation hole and a right installation hole respectively; and a pin shaft penetrates the left installation hole and the right installation hole to movably connect the left pliers head and the right pliers head. The utility model has the following advantages: the labor-saving pliers with the structure increases the acting force transmitted to the pliers heads remarkably by the labor-saving principle of the lever, so that the pliers can be relaxing and save labor in the shearing or twisting process.

Description

Labor-saving plier

Technical field

The utility model relates to a kind of hardware ﹠ tools pliers, relates in particular to a kind of labor-saving plier.

Background technology

Existing pliers, comprise: left handle and right handles, the upper end of handle and right handles is respectively arranged with left binding clip and right binding clip leftward, be respectively arranged with left installing hole and right installing hole on left binding clip and right binding clip, bearing pin is located in left installing hole and the right installing hole left binding clip and right binding clip is flexibly connected.During use, left handle and right handles are applied active force, make left binding clip and the mutual clamping of right binding clip, thereby reach the purpose of shearing.When using, the pliers of this structure relatively requires great effort.

Summary of the invention

Labour-saving labor-saving plier more when technical problem to be solved in the utility model provides a kind of use.

For solving the problems of the technologies described above, the technical solution of the utility model is: labor-saving plier, comprise: left handle and right handles, the upper end of handle is set with left binding clip leftward, be respectively arranged with slide bar and locating hole in the upper end of described right handles, slide bar is slidingly arranged in the chute of right binding clip lower end, the upper end of handle is provided with the pilot pin that cooperatively interacts with locating hole leftward, pilot pin is movably arranged in the locating hole, be respectively arranged with left installing hole and right installing hole on left binding clip and right binding clip, bearing pin is located in left installing hole and the right installing hole left binding clip and right binding clip is flexibly connected.

The utility model has the advantages that: the labor-saving plier of this structure utilizes the laborsaving principle of lever, and the active force that is delivered to binding clip part is obviously increased, thus shear or process that folder is turned round in relatively lighter, with also very laborsaving.

Among the figure: 1, left handle, 11, pilot pin, 2, right handles, 21, slide bar, 22, locating hole, 3, left binding clip, 31, left installing hole, 4, right binding clip, 41, chute, 42, right installing hole, 5, bearing pin.

The specific embodiment

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

As Fig. 1, shown in Figure 2, labor-saving plier in the present embodiment is an end cutter nippers, its structure comprises: left handle 1 and right handles 2, the upper end of handle 1 is set with left binding clip 3 leftward, be respectively arranged with slide bar 21 and locating hole 22 in the upper end of described right handles 2, slide bar 21 is slidingly arranged in the chute 41 of right binding clip 4 lower ends, the upper end of handle 1 is provided with the pilot pin 11 that cooperatively interacts with locating hole 22 leftward, pilot pin 11 is movably arranged in the locating hole 22, be respectively arranged with left installing hole 31 and right installing hole 42 on left binding clip 3 and right binding clip 4, bearing pin 5 is located in left installing hole 31 and the right installing hole 42 left binding clip 3 and right binding clip 4 is flexibly connected.

When the end cutter nippers of this structure uses, by left handle 1 and right handles 2 are outwards applied active force, right handles 2 drives slide bar 21 and upwards slides in chute 41, thereby the lower end that promotes right binding clip 4 makes right binding clip 4 rotate around bearing pin 5, right binding clip 4 opens voluntarily, steel wire is waited for that cutting thing is placed between left binding clip 3 and the right binding clip 4, then, left handle 1 and right handles 2 are inwardly applied active force, right handles 2 drive slide bars 21 in chute 41 to lower slider, thereby the lower end that promotes right binding clip 4 makes right binding clip 4 rotate around bearing pin 5, makes right binding clip 4 and left binding clip 3 mutual clampings, thereby reaches the purpose of shearing.

Because of the utility model with slide bar right handles 2 on 21 design nearer from rotation pilot pin 11, and the point of application is far away from pilot pin 11, chute 41 on the right handles 2 is far away from bearing pin 5, it is nearer from bearing pin 5 that the shearing of right binding clip 4 or folder are turned round part, two structures have all adopted lever to increase the operation principle of the equivalent arm of force, so the operator feels very light in the process of using, also very laborsaving.

Claims
