Description

Technical Field

[0001] This utility model relates to a bending pliers. Background Technology

[0002] Existing bending pliers come in two types: with and without locks. Without locks, both handles must be held and squeezed tightly during use. Existing locking bending pliers have a lock located on the side; after both handles are squeezed, the lock on one handle rotates and hooks onto the suspension point of the other handle. However, the current design and structure require both hands to operate when locking the locking pliers, making operation inconvenient and reducing processing efficiency.

[0003] Therefore, we have designed a new type of bending pliers with a lock. Summary of the Invention

[0004] In view of the problems existing in the prior art, this utility model provides a bending pliers, which aims to solve the problems of inconvenient locking operation and low processing efficiency of existing locking bending pliers.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a bending pliers, comprising a plier head assembly hinged to each other, a front handle and a rear handle, both the inner sides of the front handle and the rear handle having slots, and a suspension rod and a mounting rod respectively fixedly installed in the slots of the front handle and the rear handle at positions lower than the hinge points of the front handle and the rear handle; a suspension plate with an inclined back is rotatably mounted on the mounting rod, the lower part of one side of the suspension plate is located on a blocking shaft, and a suspension return torsion spring mounted on the mounting rod is also provided between the suspension plate and the inner side wall of the rear handle; one leg of the suspension return torsion spring abuts against the blocking shaft, and the other leg abuts against the back of the rear handle; The front end of the suspension plate is located at the hook part that cooperates with the suspension rod, and the rear end of the suspension plate extends out of the extension groove on the back of the handle.

[0006] Preferably, both the front handle and the rear handle are covered with anti-slip sleeves.

[0007] Preferably, the front handle has a groove on its front side to avoid the suspension plate hook portion.

[0008] Preferably, for ease of operation, the rear end of the suspension plate is provided with a push groove that engages with the thumb.

[0009] Preferably, in order to optimize the internal space design, the upper back of the suspension plate is provided with a groove to avoid the hinge point.

[0010] Preferably, to prevent the suspension plate from hitting the hinge point between the front and rear handles during reset, the suspension plate has a protrusion on its back that abuts against the rear handle.

[0011] The advantages of this utility model are: it can be operated with one hand, is easy to operate, conforms to manual construction operations, and improves processing efficiency. Attached Figure Description

[0014] Figure 3 This is a schematic diagram illustrating the installation principle of the suspension plate of this utility model. Detailed Implementation

[0015] like Figure 1-3 As shown, a bending pliers includes a plier head assembly 1, a front handle 2, and a rear handle 3 that are hinged together. The inner sides of both the front handle 2 and the rear handle 3 are slotted, and a suspension rod 4 and a mounting rod 5 are respectively fixedly installed in the slots of the front handle 2 and the rear handle 3 at positions lower than their hinge points. A suspension plate 6 with an inclined back is rotatably mounted on the mounting rod 5. One lower part of the suspension plate 6 is located on a blocking shaft 61, and a suspension return torsion spring 7 mounted on the mounting rod 5 is also provided between the suspension plate 6 and the inner wall of the rear handle 3. One leg of the suspension return torsion spring 7 rests against the blocking shaft 61, and the other leg rests against the back of the rear handle 3. The front end of the suspension plate 6 is located at the hook part that cooperates with the suspension rod 4, and the front handle 2 has a groove on the front to avoid the hook part of the suspension plate 6.

[0016] The rear end of the suspension plate 6 extends out of the extension groove 9 on the back of the handle 3; the rear end of the suspension plate 6 is provided with a push groove 63 that cooperates with the thumb.

[0017] The clamp head assembly 1, the front handle 2 and the rear handle 3 of this utility model are hinged to each other, which is consistent with the structure of existing products. The hinge point between the front handle 2 and the rear handle 3 is reset by a torsion spring.

[0018] In terms of the locking structure, the side locking design has been removed and moved inside the front handle 2 and rear handle 3. The suspension rod 4 and mounting rod 5 are fixed to the outer walls of the front handle 2 and rear handle 3 respectively by flattening their ends. In use, when the front handle 2 and the rear handle 3 are squeezed together, push the suspension plate 6 with your thumb to rotate it so that the hook is in front of the suspension rod 4. When you slightly loosen the front handle 2 and the rear handle 3, the suspension rod 4 engages with the hook; at this point, the one-handed operation locking is complete. Compared to conventional locking structures, it can be operated with one hand using the thumb on the inside, and the appearance is also simpler.

[0019] In normal conditions, the suspension return torsion spring 7 has one leg against the blocking shaft 61 and the other leg against the back of the rear handle 3, which keeps the suspension plate 6 in its position. When it is pushed and finally hooks the suspension rod 4, the blocking shaft 61 pushes and squeezes one leg of the suspension return torsion spring 7, causing the suspension return torsion spring 7 to deform.

[0020] When the front handle 2 and the rear handle 3 are squeezed again, the slight gap between the hook and the suspension rod 4 causes the suspension plate 6 to reset under the action of the suspension reset torsion spring 7, allowing the front handle 2 and the rear handle 3 to open.

[0021] In addition, to optimize the design and internal space, the upper back of the suspension plate 6 is provided with a groove 62 to avoid the hinge point. To prevent the suspension plate 6 from hitting the hinge point of the front handle 2 and the rear handle when it returns to its original position, the upper back of the suspension plate 6 is provided with a protrusion 64 to abut against the rear handle 3; both the front handle 2 and the rear handle 3 are covered with anti-slip sleeves 8.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
