Description
Technical Field
The utility model belongs to the technical field of the technique of hand tool locking pliers and specifically relates to a quick laborsaving formula locking pliers of opening.
Background
The existing locking pliers are generally composed of a fixed jaw, a movable jaw, a fixed handle, a movable handle, a support plate, a lifting piece, a tension spring, an adjusting screw, a rivet and the like. When the pliers are opened, the rear end of the lifting piece needs to be pushed, the rivet connected to the lifting piece and the movable handle is used as a fulcrum, and due to the lever effect, the force acting on the front end of the lifting piece pushes the movable handle and the support plate to rotate relatively, so that the movable handle is opened, the jaw is opened, and the pliers are opened. When the locking force of the movable handle is very large, the movable handle needs very large force to be pushed by the movable lifting piece to open the pliers, and the pliers are very inconvenient to use.
Disclosure of Invention
The utility model aims at solving the technical deficiencies, providing a quick laborsaving formula locking pliers of opening of reasonable in design, simple structure, with low costs, easy manufacturing, convenient to use.
The utility model adopts the technical proposal that: a quick labor-saving opening type locking pliers comprises a fixed jaw, a movable jaw, a rivet, a connecting plate, a tension spring, a limiting pin, a supporting plate, a movable handle, a fixed handle and an adjusting bolt, wherein the fixed jaw is fixedly connected to the front end of the fixed handle, the rear end of the fixed handle is connected with the adjusting bolt, the quick opening type locking pliers is characterized in that the front end of the movable jaw is connected with the fixed handle through a rivet B, the rear end of the movable jaw is connected with the front end of the movable handle through a rivet A, the connecting plate is connected to the inner side of the movable handle through a rivet C, the limiting pin is arranged on the movable handle, one end of the supporting plate is arranged on the inner side of the fixed handle, the other end of the supporting plate is connected with the connecting plate through a rivet D, the limiting pin 9 plays a role of. The utility model relates to a rationally, simple structure, with low costs, easy manufacturing, convenient to use can laborsaving open locking pliers fast.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic diagram of the state of the present invention when it is about to be opened;
fig. 3 is a schematic view of the open state of the present invention.
The labels in the figure are: 1. the rivet fixing device comprises a fixed jaw, 2 a movable jaw, 3 a rivet A, 4 a rivet B, 5 a rivet C, 6 a rivet D, 7 a connecting plate, 8 a tension spring, 9 a limiting pin, 10 a support plate, 11 a movable handle, 12 a fixed handle, 13 and an adjusting bolt.
Detailed Description
As shown in the figure, the quick labor-saving opening type locking pliers comprise a fixed jaw 1, a movable jaw 2, a rivet A3, a rivet B4, a rivet C5, a rivet D6, a connecting plate 7, a tension spring 8, a limiting pin 9, a support plate 10, a movable handle 11, a fixed handle 12 and an adjusting bolt 13, wherein the fixed jaw 1 is fixedly connected to the front end of the fixed handle 12, the rear end of the fixed handle 12 is connected with the adjusting bolt 13, the front end of the movable jaw 2 is connected with the fixed handle 12 through the rivet B4, the rear end of the movable jaw 2 is connected with the front end of the movable handle 11 through the rivet A3, the connecting plate 7 is connected with the inner side of the movable handle 11 through the rivet C5, the limiting pin 9 is arranged on the movable handle 11, one end of the support plate 10 is arranged on the inner side of the fixed handle 12, and the other.
When the pliers are to be locked, the force is applied to the movable handle 11 to move inwards, the support plate 10 pushes the connecting plate 7 to rotate around the rivet C5, the support plate 7 moves to the inner side of the movable handle 11, then the movable handle 11 continues to move inwards, and after the limiting pin 9 on the movable handle 11 presses on the support plate 10, the movable handle 11 stops moving, and the pliers are locked.
When the pliers are to be opened, the force is applied to the movable handle 11 to move outwards around the rivet A3, firstly, the limiting pin 9 on the movable handle 11 moves to the tail of the support plate 7, when the limiting pin 9 on the movable handle 11 touches the tail of the support plate 7, the force is continuously applied outwards, the limiting pin 9 pushes the support plate 7 to move outwards, the support plate 10 rotates around the rivet D6, and the pliers are opened.
Due to the connecting plate 7, the limit pin 9 is arranged on the movable handle 11, the unlocking stress point is arranged on the rivet C5, the distance from the pivot rivet A3 is reduced, and according to the lever principle, after the same acting force is applied to the movable handle 11, the force applied to the rivet C5 is far larger than the force applied to the rivet D6, and the pliers are easy to open.
