Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to pliers, in particular to a self-locking wire pliers. Background Art
[0002] Pliers are generally tools that work using the principle of leverage. They can cut hard, thin steel wires. The way to use them is to place the wire to be cut at the base of the pliers and hold it tightly at the other end, so that the wire can be cut.
[0003] However, in the process of use, other ways of use often appear. For example, clamp the bolt at the tiger's mouth and turn it, which can replace the work of the wrench. When in use, clamp the bolt with the tiger's mouth of the pliers, and then hold the end of the pliers away from the tiger's mouth, pinch it, and then turn the entire pliers. In this way, the bolt can be removed. The pliers can also be used to install the bolt. However, there will be a situation. In order to avoid the pliers turning the bolt, you need to keep holding the end of the pliers away from the tiger's mouth and turning it. In this way, there will be the force of turning and the force of holding the end of the pliers away from the tiger's mouth. This way of use will be very tiring. At this time, a self-locking wire cutter is needed to solve the above problem. Utility Model Content

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0018] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0019] See also Figures 1 to 4 A self-locking wire pliers provided by an embodiment of the utility model comprises a first clamping part and a second clamping part, the first clamping part and the second clamping part are connected by a rotating part, the first clamping part comprises a first clamp head 4 and a first handle 1 installed on the first clamp head 4, the second clamping part comprises a second clamp head 2 and a second handle 3 installed on the second clamp head 2, and is characterized in that an automatic locking component is provided on the first clamping part or the second clamping part, and the automatic locking component is used to lock or release the first clamping part or the second clamping part.
[0020] In this embodiment, when the bolt is clamped or released, the first clamping part and the second clamping part clamp the bolt, and then the automatic locking assembly locks the first clamping part and the second clamping part, and then the bolt is rotated, so that the bolt can be taken out or tightened, avoiding the need to hold the first clamping part and the second clamping part tightly with one hand, which is more labor-saving.
[0021] The automatic locking assembly includes a locking space provided on the first clamping component or the second clamping component, a positioning member arranged in the locking space, a limiting member for limiting the positioning member, a resetting member for resetting the limiting member, and a toggling assembly for toggling the limiting member.
[0022] In this embodiment, the automatic locking assembly can be installed on the first clamping component or the second clamping component.
[0023] The rotating component is a connecting shaft, and the positioning component is a disk 6 mounted on the connecting shaft. The first teeth are arranged on the circumference of the disk 6.
[0024] The limiting member includes a limiting block 7 rotatably assembled in the locking space. The side of the limiting block 7 close to the disk 6 is provided with a second tooth meshing with the first tooth. The limiting block 7 is installed in the locking space through a rotating shaft, and the number of the second tooth is at least one.
[0025] In this embodiment, when self-locking is required, it is only necessary to engage the first teeth with the second teeth, so that the disc 6 can be limited. At this time, the first clamping part and the second clamping part can be fixed, so there is no need to hold the wire cutters, which is more labor-saving.
[0026] The reset member is an energy storage member arranged in the locking space, and the energy storage member is a spring 8. One end of the spring 8 is connected to the inner wall of the locking space, and the other end is connected to the limit block 7. The toggle assembly is a toggle bar 5 installed on the rotating shaft.
[0027] In this embodiment, the toggle bar 5 can be toggled, and then the limit block 7 can be released, so that the limit block 7 and the disc 6 are not engaged. When the toggle bar 5 is loosened, the spring 8 will press against the limit block 7, which will clamp the disc 6, so that the disc 6 can be locked.
[0028] A switch can also be provided for the toggle bar 5, so that the toggle bar 5 can be limited and the effect of a reset member can be achieved. The switch can be designed in the form of a movable insert and a groove. For example, a movable insert is provided on the toggle bar 5, and a plurality of grooves are provided on the surfaces of the first clamping part and the second clamping part. In this way, the insert can be inserted into the groove, which can effectively fix the rotating shaft, thereby fixing the limit block 7 and achieving the effect of a switch.
