[0002] Tool pliers are a kind of hand tool used to clamp and fix workpieces or twist, bend and cut metal wires or nylon wires.

[0003] Since tool pliers are portable, they are often used as a tool in daily life and are widely used. In the prior art, most tool pliers have a simple structure and are not provided with safety protection components for the user's hands when in use. When the tool pliers are used to shear parts, the cut parts will fly out due to the force generated during shearing, and the shearing ports are relatively sharp. When they fly out to the user's hands, they will cause injuries to the user's hands, which is not safe enough. Therefore, it is necessary to redesign a safety tool pliers to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A safety tool pliers comprises a pliers body 1 and two handles 2. The outer walls of both sides of the pliers body 1 are fixedly connected with a mounting sleeve 4 through a fixing mechanism. The fixing mechanism comprises a fixing block 3 fixedly installed on the outer walls of both sides of the pliers body 1. The ends of the two fixing blocks 3 are fixedly connected with the inner walls of the mounting sleeve 4. The outer wall of the mounting sleeve 4 is rotatably installed with a connecting block 6 through a first connecting mechanism. The first connecting mechanism comprises a first connecting frame 5 fixedly installed on the outer wall of the mounting sleeve 4. The connecting block 6 is rotatably installed inside the first connecting frame 5. A connecting sleeve 7 is fixedly installed on the end of the connecting block 6. An extension rod 8 is slidably installed inside the connecting sleeve 7. A protective sleeve 10 is rotatably installed on the outer wall of the extension rod 8 through a second connecting mechanism. The second connecting mechanism comprises a second connecting frame 9 rotatably installed at the end of the extension rod 8. The outer wall of the second connecting frame 9 is fixedly connected to the outer wall of the protective sleeve 10.

[0023] Support plates 11 are fixedly installed on the outer walls of both sides of the installation sleeve 4, and spring telescopic rods 12 are fixedly installed on the outer walls of the two support plates 11. The telescopic ends of the two spring telescopic rods 12 are fixedly connected with a baffle 13. The outer wall of the baffle 13 is provided with a movable opening that cooperates with the connection sleeve 7. The baffle 13 is made of acrylic material. Acrylic is an important plastic polymer material that was developed earlier. It has good transparency, chemical stability and weather resistance. Therefore, it will not affect the visibility of the user when using it. In addition, the hardness of acrylic is relatively high, showing strong mechanical properties. A safety plate 15 is rotatably mounted on the outer wall of one of the handles 2 through a connecting mechanism. The connecting mechanism includes a connecting rod 14 fixedly mounted on the outer wall of the handle 2. The safety plate 15 is rotatably mounted on the outer wall of the connecting rod 14. A safety opening is opened on the outer wall of the safety plate 15. A safety rod 16 matching the safety opening is fixedly mounted on the outer wall of the other handle 2. Grip sleeves 17 are fixedly mounted on the outer walls of the two handles 2. Both grip sleeves 17 are made of insulating rubber material, and the rubber material has excellent anti-slip properties, which can increase the friction with the user's hand and improve the firmness of the grip during use.

[0024] When the utility model is used, the user grasps the handle 2 through the two grip sleeves 17, and the grip sleeve 17 made of insulating rubber can block electricity and insulate, thereby avoiding electric shock accidents when the tool pliers are used, thereby increasing the safety of the tool pliers when in use, and when the tool pliers are used, the mounting sleeve 4 can shield debris and dust to avoid the pliers body 1 from getting stuck, and the baffle 13 can shield and protect the user's hands to avoid the broken parts from flying and causing damage to the user's hands. When the baffle 13 is subjected to force, the force can be transmitted to the two spring telescopic rods 12, and the elasticity of the two spring telescopic rods 12 can absorb and buffer the force, thereby avoiding damage to the baffle 13, thereby increasing its service life;

[0025] When the tool pliers are used, the two handles 2 can be pressed inward, and then the safety plate 15 can be rotated through the connecting rod 14 so that the ear safety opening provided on the outer wall of the safety plate 15 is stuck on the outer wall of the safety rod 16, thereby making the two handles 2 in a safety locking state, and then the connecting sleeve 7 can drive the connecting block 6 to rotate inside the first connecting frame 5. At this time, the connecting sleeve 7 can move in the movable opening, and then the protective sleeve 10 can be rotated with the cooperation of the second connecting frame 9 to make the protective sleeve 10 and the pliers body 1 in a horizontal state, and then the extension rod 8 can be dragged to slide into the inside of the connecting sleeve 7, so that the extension rod 8 can drive the protective sleeve 10 to be sleeved on the end of the pliers body 1 through the second connecting frame 9, and the protective sleeve 10 can protect the end of the pliers body 1 to prevent its end from being broken during storage and carrying, thereby preventing its normal use from being affected.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
