Abstract
The utility model relates to a clamp with an automatic fastening function. The clamp with an automatic fastening function can realize auto-fastening and anti-loosing by a handle and a connecting rod driving a jaw to clamp. The opening-closing sizes of the jaw are regulated by a screw, and are suitable for the sizes of the clamped member. An auto-fastening state can be relieved by a press plate so that the jaw is loosened, and is reset by a tension spring. The clamp with an automatic fastening function has the advantages of simple structure and easy fabrication, and is a practical hand tool in factories and families.
Description
The utility model relates to a kind of gripper clamp with the auto lock function, belongs to the hand tools scope.
At present hand tools cutting pliers, the point that generally uses chewed pincers etc. and all do not possessed auto-lock function, at the smooth jaw of use, when point is chewed jaw or clamping claw clamping jobbie, need just can unclamp after certain clamping force is finished a certain course of action by manually keeping, this makes the user usually need pay the bigger power that applies in operating process, increased labour intensity, brought inconvenience to the user.
The purpose of this utility model need manufacture and design a kind of gripper clamp with auto lock function exactly, can keep clamping force behind the clamping something, and the energy self-locking, and is easy to operate, laborsaving.
The purpose of this utility model is to realize like this, it connects and composes main body of the present utility model by two half-calipers with hinge, be provided with connecting rod (5) between flexible handle (1) and fixed handle (2), its end and flexible handle (1) are hinged, and the other end heads on adjusts screw (7); In succession with extension spring (8) between moving jaw (3) and the fixed handle (4), on flexible handle (1), also be provided with simultaneously the pressing plate (6) of easy rotation, form quadric chain by fixed handle (2), flexible handle (1), moving jaw (3) and connecting rod (5).When the pliers of holding with a firm grip, flexible handle (1) drive moving jaw (3) and connecting rod (5) motion, between connecting rod (5) and flexible handle (1) two hinge one section when being in line, then moving jaw (3) clamps with regular jaw (4) and is held part and self-locking.Its jaw folding size can be controlled by regulating adjustment screw (7).When pressing dynamic pressure plate (6), then can remove self-locking state, jaw unclamps, and extension spring (8) resets jaw etc., and this gripper design is rationally, light and flexible, jaw can be designed to various ways, is convenience, labour-saving instruments that people often use.
Concrete structure of the present utility model and enforcement are illustrated by following accompanying drawing.
As shown in Figure 1, by flexible handle (1), fixed handle (2), moving jaw (3), regular jaw (4) and connecting rod (5), pressing plate (6), adjustment screw (7), extension spring (8) is formed.Fixed handle (2) is linked as integral body with regular jaw (4) with two rivets (9); Flexible handle (1) is connected with hinge (10) with moving jaw (3); Moving jaw (3) is connected with hinge (11) with fixed handle (4); Connecting rod (5) one ends are connected with hinge (12) with flexible handle (1), and the other end heads on the adjustment screw (7) that is arranged in fixed handle (2) groove; Extension spring (8) one ends are fixed on the moving jaw (3).The other end is fixed on the fixed handle (2); Pressing plate (6) is connected on the flexible handle (1) with hinge (13).Form a quadric chain by flexible handle (1), fixed handle (2) with moving jaw (3) and connecting rod (5).When flexible handle of holding with a firm grip (1) and fixed handle (2), flexible handle (1) drivening rod (5) is around heading on the top swing of adjusting screw (7), and then drive flexible handle (1) promotion moving jaw (3), thereby reach the clamping object around hinge (11) swing.When between two hinges (10) on moving to connecting rod (5) and flexible handle (1) and the hinge (12) one section becomes straight line, as shown in Figure 2, be taken at clamped condition, then quadric chain self-locking, one of pressing plate this moment (6) corrects the semicircle boss that heads on the connecting rod (5), connecting rod (5) and flexible handle (1) can not move again, and gripped object can not become flexible.When pressing dynamic pressure plate (6) terminal, pressing plate (6) is around hinge (13) swing, and its other end then promotes connecting rod (5), and self-locking state is removed.Extension spring (8) then makes moving jaw (3) unclamp to reset, and adjusts screw (7) and then can change the folding degree of jaw and the position of self-locking by regulating.
Moving jaw of the present utility model (3) and regular jaw (4) can be manufactured point and chew jaw, smooth jaw, clamping claw or other form.Moving jaw (3) and regular jaw (4) adopt the 40Cr high-quality alloy steel, through forging quality controling machine processing; Flexible handle (1), fixed handle (2), connecting rod (5) and the available 1～2.5mm steel plate spare of pressing plate (6) are pressed into shape.Its jaw of gripper clamp of this band auto lock function and handle form are expansible to become various ways, as the craft that is used to forge the worker is very laborsaving and convenient with instrument etc.
