[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1-Figure 5 As shown, the utility model provides a technical solution: an aluminum alloy wire clamp, comprising a main board 1, a connecting plate 2 is installed at the front end of the main board 1, a pulling arm 3 is installed on the top of the connecting plate 2 through a rotating shaft, a pulling ring 4 is installed on the end of the pulling arm 3 away from the connecting plate 2 through a rotating shaft, a transverse through groove 5 used in conjunction with the pulling ring 4 is opened on the surface of the main board 1, an upper jaw 6 is rotatably connected to the bottom of the connecting plate 2 through a rotating shaft, a lower jaw 7 is installed at the front end of the main board 1, a reset spring 8 is installed inside the pulling arm 3, a spring pin 9 is slidably connected inside the reset spring 8, a fixing rod 10 is inserted at the front end of the spring pin 9, a bottom of the fixing rod 10 is fixedly connected to a bottom plate 11, a front end of the pulling arm 3 is fixedly connected to a shell 12, a control rod 13 is slidably connected to the top of the shell 12, a control block 14 is fixedly connected to the top of the control rod 13, a first T-shaped block 15 is fixedly connected to the bottom of the control block 14, and both sides of the bottom of the shell 12 are slidably connected to The connecting block 16, the bottom of the facing surface of the connecting block 16 is fixedly connected to the limiting block 17, the top of the facing surface of the connecting block 16 is fixedly connected to the second T-block 18, and the surface of the bottom plate 11 is provided with a first through groove 19 used in conjunction with the connecting block 16. By pressing the control block 14, the control rod 13 drives the first T-block 15 to move downward, so that the first T-block 15 squeezes the second T-block 18 to move the second T-block 18 to the side away from each other, and the movement of the second T-block 18 causes the connecting block 16 to drive the limiting block 17 to disengage from the bottom of the bottom plate 11, and the limitation on the bottom plate 11 is released. By moving the bottom plate 11 downward, the fixing rod 10 is disengaged from the inside of the spring pin 9, and the limitation on the spring pin 9 is released. The user pulls the spring pin 9 out of the inside of the pulling arm 3, thereby releasing the limitation on the reset spring 8, so that the user can replace the reset spring 8 and reduce the impact caused by the aging of the reset spring 8.

[0022] Reference Figure 3As shown, in this embodiment: the first spring 20 is fixedly connected to both sides of the shell 12, and the end of the first spring 20 away from the shell 12 is fixedly connected to the connecting block 16, and the elastic force generated by the first spring 20 is used to limit the connecting block 16, and the limiting block 17 is limited to the bottom of the bottom plate 11, thereby preventing the bottom plate 11 from detaching downward, causing the fixing rod 10 to detach from the inside of the spring pin 9.

[0023] Reference Figure 3 As shown, in this embodiment: the surface of the control rod 13 is sleeved with a second spring 21, the top of the second spring 21 is fixedly connected to the bottom of the control block 14, and the bottom of the second spring 21 is fixedly connected to the top of the shell 12. The elastic force generated by the second spring 21 limits the position of the control block 14, so that the first T-block 15 will not squeeze the second T-block 18 during normal use, preventing the second T-block 18 from driving the connecting block 16 to cause the limit block 17 to shift.

[0024] Reference Figure 5 As shown, in this embodiment: both sides of the second T-block 18 are fixedly connected with the first slider 22, and both sides of the shell 12 are provided with a first slide groove 23 used in conjunction with the first slider 22. Through the cooperation of the first slider 22 and the first slide groove 23, the second T-block 18 is made more stable when moving, and the displacement of the second T-block 18 when moving is reduced.

[0025] Reference Figure 5 As shown, in this embodiment: the second sliders 24 are fixedly connected to both sides of the first T-block 15, and the second slide grooves 25 used in conjunction with the second sliders 24 are provided on both sides of the shell 12. When the first T-block 15 moves up and down, the cooperation between the second sliders 24 and the second slide grooves 25 assists the movement of the first T-block 15 and prevents the first T-block 15 from tipping over when moving.

[0026] Reference Figure 1 As shown, in this embodiment: the main board 1, the connecting plate 2, the pull arm 3, the pull ring 4, the transverse through groove 5, the upper jaw 6 and the lower jaw 7 are all made of high-strength aluminum alloy, which has the advantages of high strength, light weight and easy to carry and use.

[0027] The working principle of the utility model is as follows: the user presses the control block 14 to make the control rod 13 drive the first T-block 15 to move downward, so that the first T-block 15 squeezes the second T-block 18 to move the second T-block 18 to the side away from each other, and the movement of the second T-block 18 makes the connecting block 16 drive the limiting block 17 to disengage from the bottom of the bottom plate 11, thereby releasing the limit on the bottom plate 11, and the fixing rod 10 is disengaged from the inside of the spring pin 9 by moving the bottom plate 11 downward, thereby releasing the limit on the spring pin 9, and the user pulls the spring pin 9 out of the inside of the pulling arm 3, thereby releasing the limit on the reset spring 8, so that the user can replace the reset spring 8 and reduce the influence caused by the aging of the reset spring 8. After the replacement is completed, the spring pin 9 is inserted into the inside of the reset spring 8, and then the fixing rod 10 is disengaged from the inside of the spring pin 9. The fixed rod 10 is inserted into the interior of the spring pin 9, and the connecting block 16 is driven by the first spring 20 to move the limit block 17 to the bottom of the bottom plate 11, thereby limiting the bottom plate 11. At the same time, the elastic force generated by the first spring 20 limits the connecting block 16, and limits the limit block 17 to the bottom of the bottom plate 11, thereby preventing the bottom plate 11 from disengaging downward, causing the fixed rod 10 to disengage from the interior of the spring pin 9. The first slider 22 and the first slide groove 23 are used in conjunction with each other, so that the second T-block 18 is more stable when moving, and the deviation of the second T-block 18 when moving is reduced. When the first T-block 15 moves up and down, the second slider 24 and the second slide groove 25 are used in conjunction with each other to assist the movement of the first T-block 15, thereby preventing the first T-block 15 from tipping over when moving.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
