Description

Pliers with pliers body

Technical Field

Background

Pliers are hand tools used to grip, hold a work piece or twist, bend, and shear a wire. In the prior art, pliers mainly comprise a handle, a pliers shaft and a pliers head, and the pliers head is driven to rotate by rotating the handle by utilizing the lever principle so as to open or close a jaw to process a workpiece. When the processing of the workpiece is finished, the handles are manually operated to open the jaw again for the next processing. However, opening the jaws by manually operating the handles is cumbersome, and to solve this problem, some pliers are provided with springs on both handles. When the free ends of the two handles in the pliers are close to each other so that the jaws are closed, the spring is compressed; after external force on the handles is withdrawn, under the action of elastic restoring force of the springs, the springs push the free tail ends of the two handles to be away from each other so as to drive the pliers heads to move, and further the jaws automatically open, so that the pliers are more convenient to use.

However, the following problems exist with the current use of springs to automatically open the jaws: in the prior art, when the spring is installed, a bulge is usually arranged on one side of each handle facing the other handle, and the opposite ends of the spring are respectively sleeved on the bulges of the two handles. Because the middle part of the spring is not guided, the spring is easy to stretch and deform when the handle rotates, and when the handle rotates, the bulge on the handle can resist the spring, so that the spring is easy to be deformed by pressing and can not be restored to the original state when in subsequent use, and the service life of pliers is influenced. Furthermore, since the spring itself has a minimum thickness requirement under fixed spring force requirements, and when installed, the minimum thickness of the spring may be greater than the spacing between the two handles when the jaws are closed, affecting the closure of the jaws.

When a cutting operation is performed, a force is applied to the two handles 23, causing the second ends 232 of the two handles 23 to approach each other until the two handles 23 are in the minimum open amplitude position to close the jaws. In this process, the two handles 23 respectively press the two abutment arms 31 of the spring 30, so that the spring 30 is elastically deformed (fig. 4).

After the shearing operation is finished, the external force on the handles 23 is removed, the two abutting arms 31 on the elastic sheet 30 abut against the two handles 23, under the action of the elastic restoring force of the elastic sheet 30, the two handles 23 are pushed to rotate around the handle shaft 50 to be opened until the two handles 23 are positioned at the maximum opening amplitude position, in the process, the two handles 23 drive the crank 25 of the corresponding clamp body 20 to move through the connecting shaft 60, and pull the handle shaft 50 on the other clamp body 20 and one end of the clamp head 21 connected with the handle shaft 50 to move towards the direction close to the other clamp head 21 through the second connecting rod 253 of the corresponding crank 25, so that the clamp head 21 rotates around the clamp shaft 40 to enable one ends of the two clamp heads 21 provided with the cutting edges 210 to be separated from each other, and the jaws are opened again, so that the clamp head is convenient for next use.

When the two handles 23 are located at the maximum opening width position, the abutting arms 31 of the elastic sheet 30 are separated from contact with the groove walls surrounding the mounting cavity 234, and the connection parts of the abutting arms 31 and the connecting arms 321 are blocked at the periphery of the corresponding connecting shafts 60, so that the second ends 232 of the handles 23 are prevented from moving in the directions away from each other, and the ends of the two binding clip 21 away from the cutting edge 210 are prevented from being accidentally touched and damaged.

The pliers 100 are connected with the handles 23 of the two pliers bodies 20 through the elastic sheets 30, and when in use, the free ends of the two handles 23 are pushed away from each other by the elastic restoring force of the elastic sheets 30 to drive the pliers heads 21 to move, so that the jaws automatically open, and the pliers are beneficial to use. And compared with a spring, the spring plate 30 does not need to be guided, is not easy to deform, and can prolong the service life of the pliers 100.

The handles 23 of the pliers 100 are provided with the mounting cavities 234, and the opposite ends of the elastic sheet 30 are respectively inserted into the mounting cavities 234 of the two handles 23, so that the pliers are convenient to install; when the handles 23 of the pliers 100 are moved closer to each other to close the jaws, the spring 30 can be further received by the mounting cavity 234, so that the spring 30 is prevented from affecting the closing of the jaws.

The pliers 100 described above, the pliers body 20 includes the pliers head 21, the handle 23 and the crank 25, one end of the crank 25 is rotatably connected with the corresponding handle 23, and the other end of the crank 25 is rotatably connected with the first end 231 of the handle 23 of the other pliers body 20, so that the length of the arm of force can be increased, and compared with the pliers 100 of the prior art, the pliers are more labor-saving in use.

It is understood that the function of the pliers 100 is not limited to the shearing function in the present embodiment, and may be pliers having a twisting function or the like in the prior art, and the blade 210 may be omitted.
