[0002] An insulated wire clamp is a tool used during live work in power systems. Its primary function is to operate overhead conductors, such as clamping, securing, and tightening them, while ensuring good insulation between the operator and the live conductors to prevent electric shock accidents. However, existing insulated wire clamps generally require a worker to firmly grasp the clamp to clamp the conductor. When the worker releases their grip, the clamping end of the clamp also releases. This prevents the worker from temporarily attaching the clamp to the conductor while performing other operations, thus affecting the normal operation of power work. Summary of the Invention

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings of the embodiments of the present invention. Obviously, the drawings described below only relate to some embodiments of the present invention and are not intended to limit the present invention. Among them:

[0017] Figure 2 Shown is a schematic diagram of the local structure of the invention. DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0019] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0020] This embodiment provides an insulating clamping rod, such as Figure 1 As shown, a first clamp 2 is fixedly installed at one end of the fixed rod 1, and a second clamp 3 is rotatably installed on the first clamp 2. The second clamp 3 can move away from or closer to the second clamp 3 along the radial direction of the fixed rod 1. At the same time, a clamping interval is constructed between the first clamp 2 and the second clamp 3.

[0021] When performing electrical work, the staff can hold one end of the fixing rod 1 to move the end on which the first clamp 2 and the second clamp 3 are installed close to the wire, and control the second clamp 3 to move away from the first clamp 2, thereby expanding the range and opening of the clamping interval, making it easier for the wire to enter the clamping interval. When the wire enters the clamping interval, the second clamp 3 is controlled to approach the first clamp 2, and the wire is fixed in the clamping interval by narrowing the range of the clamping interval, thereby completing the clamping work of the wire, which is convenient for the staff to subsequently manipulate the wire.

[0022] like Figure 1 As shown, because the fixing rod 1 is long, when the staff holds one end of the fixing rod 1 and uses the fixing rod 1 to install the first clamp 2 and the other end of the second clamp 3 to clamp the wire, it is inconvenient for the staff to control the movement of the second clamp 3. Therefore, in this application, a driving component 5 is provided on the fixing rod 1 to facilitate the staff to drive the second clamp 3 to move.

[0023] like Figure 1 As shown, one end of the second clamp 3 passes through the first clamp 2, and the second clamp 3 is rotatably connected to the overlapping position of the first clamp 2, and the second clamp 3 passes through one end of the first clamp 2 and is hinged with a driving rod 51, and the driving rod 51 extends away from one end of the second clamp 3 to the hand-holding position of the fixed rod 1. Therefore, when the staff holds the fixed rod 1, they can control the movement of the second clamp 3 on the first clamp 2 by pushing and pulling the driving rod 51, thereby realizing the opening and closing of the clamping interval, thereby facilitating the staff's control of the wire clamping.

[0024] like Figure 2As shown, a fixing sleeve is provided on the fixing rod 1 with a fixing ring 52, and a holding piece 54 is provided on the outside of the fixing ring 52, and the holding piece 54 is rotatably connected to the hinge cavity 53 and the driving rod 51 on the fixing ring 52 respectively. This arrangement converts the linear motion of the driving rod 51 into the circular motion of the holding piece 54. Therefore, when the staff clamps the wire, they can control the holding piece 54 to rotate in the hinge cavity 53 to achieve this, because when the holding piece 54 rotates, it will achieve the effect of pushing and pulling the driving rod 51 through the hinge point with the driving rod 51, thereby realizing the function of controlling the clamping interval.

[0025] like Figure 2 As shown, the gripping member 54 is coaxially fixed with the limit gear 42 at the hinge point in the hinge cavity 53, and the outer portion of the limit gear 42 is meshed with a limit rack 41 that is slidably connected to the hinge cavity 53 through teeth. Therefore, when the clamping interval is opened and closed, the limit gear 42 is driven to rotate, and then the limit rack 41 is synchronously driven to move along the axial direction of the fixed rod 1. Figure 1 and Figure 2 , it can be known that when the clamping interval is opened, the limit gear 42 will drive the limit rack 41 to move away from the second clamp 3, and when the clamping interval is closed, the limit gear 42 will drive the limit rack 41 to move toward the second clamp 3.

[0026] like Figure 2 As shown, a reset groove 55 is provided on the limit gear 42, and a reset torsion spring 56 fixedly connected to the hinge cavity 53 is fixedly installed in the reset groove 55. In the initial state of the reset torsion spring 56, the clamping interval is in an open state. Therefore, when the first clamp 2 and the second clamp 3 consider clamping the wire, the reset torsion spring 56 in the reset groove 55 is in a compressed state. Therefore, after the external force disappears, the reset torsion spring 56 will quickly reset and drive the limit gear 42 to reverse, and the clamping space between the first clamp 2 and the second clamp 3 will be in an open state again, which is convenient for the next guide clamping.

[0027] like Figure 2 As shown, a limiting sleeve 43 is provided on the fixing rod 1, and an accommodating cavity 46 for accommodating the fixing rod 1 is provided in the limiting sleeve 43, and a limiting screw groove 47 threadedly connected to the accommodating cavity 46 is provided on the fixing rod 1. Therefore, after the clamping interval is closed, the limiting sleeve 43 can be screwed in to compress the volume of the accommodating cavity 46, so that one end of the limiting sleeve 43 conflicts with the limiting rack 41, restricting its next movement, thereby achieving the effect of fixing the clamping state of the wire clamping rod, so that the wire clamping rod will still be hung on the wire and will not fall off after the staff lets go, which is convenient for the staff to perform other electrical work. After the clamping is completed, the limiting sleeve 43 can be rotated outward to make the limiting sleeve 43 away from the limiting rack 41, providing space for the movement of the limiting rack 41, and releasing the movement restriction of the limiting rack 41.

[0028] like Figure 2As shown, a guide member 44 is provided on the side of the limiting rack 41 close to the fixed ring 52, and a guide groove 45 is also provided in the hinge cavity 53 to slide with the guide member 44. The cooperation between the guide groove 45 and the guide member 44 can provide a clear movement path for the limiting rack 41, ensuring that the limiting rack 41 does not deviate from the predetermined trajectory during movement.

[0029] from Figure 2 It can be seen that the cross-sections of the guide member 44 and the guide groove 45 are both T-shaped. Because the design of the T-shaped structure can provide a higher load-bearing capacity and can withstand larger forces and torques, in this application, the T-shaped guide groove 45 can withstand the weight of the limit rack 41 and the impact force generated when the limit rack 41 moves, ensuring the smooth movement of the limit rack 41.

[0030] like Figure 2 As shown, there are several anti-slip grooves 48 in a linear array on the limiting sleeve 43, and the material of the limiting sleeve 43 is rubber. It mainly uses the insulating properties of rubber to provide insulation protection for the staff to prevent the staff from electric shock accidents when touching the wires or performing related operations. The setting of the anti-slip grooves 48 can significantly increase the friction between the staff's palm and the limiting sleeve 43 by increasing the roughness of the contact surface of the limiting sleeve 43, thereby avoiding the wire clamping rod from sliding or slipping during use, thereby ensuring the stable operation of the power work.

[0031] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
