[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-5 The utility model provides a technical solution: a labor-saving pliers that prevent the invasion of foreign objects from the outside, comprising: a left handle body 1 and a right handle body 2, a left pliers head body 3 is fixedly installed at one end of the left handle body 1, a right pliers head body 5 is provided on the top of the left pliers head body 3, and an extended handle 7 is installed at the bottom of the left handle body 1 and the right handle body 2.
[0022] Specifically: the handle of the device is lengthened by lengthening the handle 7, thereby increasing the torque and making the pliers more perfect.
[0023] In one embodiment, a connection groove 301 is opened on the surface of the left clamp body 3, a sliding rod 302 is fixedly installed on the surface of the left clamp body 3, and a connection rod 4 is embedded in the inner wall of the connection groove 301.
[0024] Specifically, the connecting rod 4 is embedded in the inner wall of the connecting groove 301 so that the left clamp head body 3 can be connected to other components through the connecting rod 4, making the device more perfect.
[0025] In one embodiment, a second connecting groove 501 is opened on the surface of the right pliers body 5 , a fixing rod 502 is fixedly installed on the surface of the right pliers body 5 , and the inner wall of the second connecting groove 501 is sleeved on the surface of the connecting rod 4 .
[0026] Specifically, the left clamp body 3 and the right clamp body 5 are connected together through the connecting rod 4, and the left clamp body 3 and the right clamp body 5 are used to cut the material, making the device more perfect.
[0027] In one embodiment, a sliding groove 201 is opened on the surface of the right handle body 2, and the inner wall of the sliding groove 201 is movably mounted on the surface of the fixed rod 502. A fixed groove 202 is opened on the surface of the right handle body 2, and the inner wall of the fixed groove 202 is mounted on the surface of the sliding rod 302.
[0028] When the clamp 2 is opened, the sliding bar 302 moves to the top of the sliding bar 301, driving the right clamp body 5 to open and put the object to be cut into. When the clamp 2 is opened, the sliding bar 302 moves to the other end of the inner wall of the fixing groove 202 by pressing the right handle body 2 downward, thereby pushing the right clamp body 5. During the downward pressing process of the right handle body 2, the connection between the sliding bar 201 and the fixing rod 502 causes the right clamp body 5 to rotate around the connecting rod 4, so that the right clamp body 5 and the connecting rod 4 are clamped together, thereby achieving the purpose of cutting. The fixing groove 202 and the sliding bar 302 are hidden between the left clamp body 3 and the right clamp body 5. The two clamp planes are parallel to the fixing groove 202 to form a sealed cavity, which effectively solves the intrusion of foreign matter from the outside.
[0029] In one embodiment, a handle cover 6 is fixedly provided on the bottom of the surface of the left handle body 1 and the right handle body 2 .
[0030] Specifically, the handle cover 6 is provided on the surfaces of the left handle body 1 and the right handle body 2 to increase the friction when the device is in use, making the device more convenient to use.
[0031] In one embodiment, a threaded rod 8 is fixedly installed at one end of the extended handle 7, and a fixing plate 9 is sleeved on the surface of the threaded rod 8. The surface threads of the two threaded rods 8 are respectively embedded in the bottom of the left handle body 1 and the right handle body 2.
[0032] Specifically: when the device is used, it is necessary to increase the handle length. By rotating the two extension handles 7, the threaded rods 8 are respectively embedded in the interior of the left handle body 1 and the right handle body 2, so that the handle length is increased and the torque is increased. The fixing piece 9 sleeved on the surface of the threaded rod 8 makes the extension handle 7 more stably installed, making the device more perfect.
[0033] Working principle: When the device starts to be used, the left handle body 1 and the right handle body 2 are opened outwards, and the slide groove 201 is sleeved on the surface of the fixed rod 502, so that the right handle body 2 and the right pliers body 5 are connected together, and the fixed groove 202 is sleeved on the surface of the slide rod 302. When the right handle body 2 is opened outwards, the slide rod 302 moves to the top of the slide groove 201, driving the right pliers body 5 to open, and the left handle body 1 opens and drives the left pliers body 3 to open. The object to be cut is placed between the openings of the left pliers body 3 and the right pliers body 5. The right handle body 2 is pressed down to make the slide rod 302 move to the other end of the inner wall of the fixed groove 202, thereby pushing the right pliers body 5. During the downward pressing process of the right handle body 2, the right pliers body 5 rotates around the connecting rod 4 through the connection between the slide groove 201 and the fixed rod 502. The right pliers body 5 and the left pliers body 3 are clamped together to achieve the purpose of shearing. The fixing groove 202 and the sliding rod 302 are hidden between the left pliers body 3 and the right pliers body 5. The two pliers planes are in parallel contact with the fixing groove 202 to form a sealed cavity, which effectively solves the invasion of foreign matter from the outside. When the device is in use, the handle cover 6 fixedly sleeved on the bottom of the surface of the left handle body 1 and the right handle body 2 increases the friction of the device during use, making it more convenient to use. The threaded rods 8 fixedly installed at one end of the two extended handles 7 are respectively screwed into the interior of the left handle body 1 and the right handle body 2, so that the handle of the device is lengthened, the torque is increased, and the device is more perfect.
[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
