Abstract

The utility model relates to a pair of multifunction convenient pincers which belongs to a pair of clamping and twisting pliers and comprises a left pincers body, a right pincers body, and a pincers cheek. A positive penetration groove arranged on the left pliers body is connected to the pincers cheek, a ratchet bar is arranged on the upper side of the positive penetration groove, and a ratchet pawl sleeve is sheathed on the pincers cheek. Different jaw openings can be formed when the right pincers body moves along the positive penetration groove. A fulcrum is formed when the ratchet pawl sleeve is propped on the ratchet bar, and pincers teeth are slant points. The utility model can be used as a pair of ordinary clamping and twisting pliers and a grip wrench, can clamp and twist large objects, can effectively clamp and twist round smooth objects, and has large jaw opening.

Description

A kind of pliers

The utility model is to turn round pincers about a kind of folder, and is particularly many with convenient pincers.

Pliers is divided into folder and turns round pincers class (turning round pincers, slip-joint pliers as folder), cutting nipper class (as various cutting nippers) and pipe vice class etc.The cutting nipper class is used to shear metal material etc., and pipe vice is used to reverse pipe, and folder is turned round the pincers class and is mainly used in folder and turns round object.Press from both sides and turn round the pincers class, be difficult to press from both sides and turn round bigger object because span of jaw is little, because it is the pincers tooth is the little tooth of isosceles triangle, relatively poor again to reversing the circular object effect, thereby can not be used to reverse pipe etc., influenced and pressed from both sides the range of application of turning round pincers.

The purpose of this utility model provides a kind of pliers of multi-functional, applied range.

Pliers of the present utility model is made up of left caliper (1), right caliper body (4), the pincers cheeks (2), it is the saturating groove of forward (1A) that left caliper (1) is gone up the position that is connected with the pincers cheeks (2), at the saturating groove of forward (1A) upside ratchet bar (1B) is arranged, be with ratchet cover (3) on the pincers cheeks (2).

The pincers odontoid is a helical teeth, and left caliper (1) upper clamp tooth is (or upwards) inclination downwards, and right caliper body (4) upper clamp tooth upwards (or downwards) tilts.

When the pliers folder was turned round object, the pincers cheek (2) of fixedlying connected with right caliper body (4) moved in the saturating groove of forward (1A), forms different spans of jaw, adapts with folded object; When clamping object, the ratchet cover (3) on the pincers cheeks (2) withstands on the ratchet bar (1B) of the saturating groove of forward (1A) upside, fixes the pincers cheek (2), forms fulcrum, thereby tightly clamps object.

Between left caliper (1) handle part and right caliper body (4) handle part, have and open mechanism automatically, automatically opening mechanism is made up of connecting rod (7), extension spring (6), stage clip (8), pin (5), connecting rod (7) right-hand member and right caliper body (4) are hinged by pin (5), extension spring (6) is connected between the pin joint right side and right caliper body (4) handle end of connecting rod (7), connecting rod (7) left end embeds in left caliper (1) groove, and stage clip (8) places between the handle end of connecting rod (7) left end and left caliper (1).When light pressure handle is clamped object, extension spring (6) tension, release handle, extension spring (6) opens jaw by retracting connecting rod (7), breaks away from object.After clamping object jaw closure, continue to hold handle, connecting rod (7) left end roof pressure stage clip (8), stage clip (8) compression stress makes right caliper body (4) that thrust upwards be arranged by the transmission of connecting rod (7), form upwards microdisplacement of right caliper body (4), eliminate the gap between ratchet cover (3) and the ratchet bar (1B), make ratchet cover (3) withstand ratchet bar (1B) voluntarily, form fulcrum, clamping article.When release handle, stage clip (8) return, right caliper body (4) be the microdisplacement return downwards, and ratchet cover (3) breaks away from ratchet bar (1B), continues release handle, with foregoing one auspicious, under extension spring (6) effect, retract connecting rod (7) jaw is opened fully.

The utility model is because left caliper (1) is shaped on the saturating groove of forward (1A), the pincers cheeks (2) move in the saturating groove of forward, form different jaw opening widths, cooperate the formation fulcrum with ratchet bar (1B) by ratchet cover (3), so the jaw opening width can improve greatly, can not only press from both sides and turn round less object, also can press from both sides and turn round bigger object, range of application improves greatly.Because the pincers odontoid is a helical teeth, left caliper (1) and right caliper body (4) pincers tooth tilts to different directions respectively, is to tilt to a direction with respect to the rotation of object, and this auspicious torsion effect to circular object is better, can be used as the pipe vice use; To hexagonal worn screw, particularly soket head cap screw (being difficult to turn with common instrument), more easily turn simultaneously, result of use is fine, has improved range of application greatly.From top two aspect situations, the utility model not only has folder and turns round the function of pincers, slip-joint pliers, and has the function of pipe vice, has formed the multi-functional characteristics of the utility model.The utility model is provided with and opens mechanism automatically, and it is quite convenient that folder is turned round object, nimbly and freely.The utility model is the practical and convenient instrument of factory, maintenance store, family.

Fig. 1 is the utility model embodiment front view;

Fig. 2 is an A-A profile among Fig. 1.

Among the figure, 1 is left caliper, and 1A is a forward elongated slot on the left caliper, and 1B is a ratchet bar on the left caliper, and 1C is a side direction elongated slot on the left caliper, and 2 are the pincers cheek, and 3 is the ratchet cover, and 4 is right caliper body, and 5 is pin, and 6 are extension spring, and 7 is connecting rod, and 8 is stage clip.

Now in conjunction with the accompanying drawings the not detailed structure of part is further specified.Left caliper (1) is shaped on the saturating groove of forward (1A) and matches with the pincers cheeks (2), the ratchet bar (1B) of the saturating groove of forward (1A) upside with clamp the cheeks (2) on the ratchet cover (3) that is with match.Left caliper (1) and right caliper body (4) form by the pincers cheeks (2) and are connected, but the two can resemble the connection that superposes the slip-joint pliers, and also insertable connection is visible as the latter's connected mode among the figure.Left caliper among Fig. 2 (1) has the saturating groove of side direction (1C), and right caliper body (4) inserting side is in saturating groove (1C), and described ratchet bar (1B) is divided into two of front and back, and ratchet cover (3) is divided into two of front and back.The saturating groove of side direction (1C) is bigger than the saturating groove of forward (1A) length.
