Abstract

The utility model relates to a novel water pump pincers with self-modulation function, constitute including the fixed pincers body, the slip pincers body, movable nozzle, connecting rod, extension spring and switch, traditional self-modulation water pump pincers are generally articulated through quick sliding adjustment ratchet mechanism by the fixed pincers body with the slip pincers body, carry out the parallel clamping function of keeping silent through the ratchet at inslot arbitrary meshing position, the utility model discloses saved ratchet mechanism, directly followed fixed pincers body middle part upward movement by movable nozzle and the slip pincers body, through reducing gradually and fixed pincers body middle part between clearance realize pressing from both sides tight function, the utility model provides a novel self-modulation water pump pincers of simple structure, reasonable in design, easy processing.

Description

Self-adjusting water pump pliers

Technical Field

The utility model belongs to the technical field of manual hardware and tools technique and specifically relates to a self-modulation water pump pincers with quick adjustment function.

Background

The traditional self-adjusting water pump pliers are generally formed by hinging a fixed pliers body and a sliding pliers body through a quick sliding adjusting ratchet mechanism, and performing jaw parallel clamping function at any meshing position in a groove through a ratchet, wherein the ratchet mechanism is complex in structure, high in processing difficulty and high in cost.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing a self-adjusting water pump clamp with simple structure, reasonable design and easy processing.

The utility model adopts the technical proposal that: self-adjusting water pump clamp, including the solid fixed pincer body, the slip pincer body, activity mouth, connecting rod, extension spring and switch constitution, the slip pincer body passes through rivet I with the activity mouth and is connected, and the switch passes through rivet II to be fixed on the slip pincer body, and connecting rod one end is passed through rivet III and slip pincer body coupling, and the other end passes through the pin joint in the solid fixed pincer body elongated slot, and extension spring one end is hung at the connecting rod, and one end is hung on rivet IV, the utility model discloses but the automatically regulated opening size, the maximum opening volume of automatic recovery when loosening, simple structure, processing is easy, convenient to use.

Description of the drawings:

the figure is a schematic structural diagram of the utility model;

the second figure is a schematic structural view when the utility model is opened;

FIG. three is a state diagram of the present invention when clamping a workpiece;

the labels in the figure are: 1. the fixed pliers comprise a fixed pliers body, 2 a movable nozzle, 3 a rivet I, 4 a sliding pliers body, 5 a rivet II, 6 a switch, 7 a rivet III, 8 a tension spring, 9 a connecting rod, 10 a pin, 11 a rivet IV.

Detailed Description

When a workpiece is clamped, the sliding clamp body 4 slides along the middle of the fixed clamp body 1 of the movable nozzle 2, when the movable nozzle 2 is contacted with the workpiece, the movable nozzle 2 stops moving, the sliding clamp body 4 continues to rotate around the rivet I3, the movable nozzle 2 is driven to gradually reduce the gap between the movable nozzle 2 and the middle of the fixed clamp body 1, the movable nozzle 2 is driven to continue moving upwards along the middle of the fixed clamp body 1, the workpiece is clamped after the gap between the movable nozzle 2, the head of the sliding clamp body 4 and the middle of the fixed clamp body 1 is eliminated, when the movable nozzle is loosened, the tension spring 8 pulls the connecting rod 9 to rotate around the rivet III 7, the connecting rod 9 pushes the fixed clamp body 1 to move upwards through the long groove on the handle of the fixed clamp body 1, the purpose of opening the clamp is achieved, after the use, the switch 6 and the upper part of the connecting rod 9 can be hooked together to enable the clamp body.

Claims

1. The self-regulating water pump pliers includes fixed pliers body, sliding pliers body, movable mouth, connecting rod, tension spring and switch, the sliding pliers body is connected with movable mouth by means of rivet and can be slided in the middle portion of fixed pliers body, and is characterized by that the middle portion of the fixed pliers body is made into a structure with narrow upper portion and wide lower portion, and the head portion of the sliding pliers body is made into a cam structure, when the workpiece is held, the sliding pliers body and movable mouth can be slided along the middle portion of fixed pliers body, when the movable mouth is contacted with workpiece, the movable mouth can be stopped from moving, the sliding pliers body can be continuously rotated around the rivet to drive the movable mouth to gradually reduce the gap between the movable mouth and middle portion of fixed pliers body, and along the middle portion of fixed pliers body the movable mouth can be continuously moved upwards, when the gap between movable mouth, head portion of sliding pliers body and middle portion of fixed pliers body is eliminated, and when the movable mouth is loosened, the tension spring can be used for pulling connecting, so as to achieve the purpose of opening the pliers.
