[0002] When the DC system is working and the battery is installed and modified, the plug-in low-voltage arrester needs to be removed. Since the low-voltage arrester has not been unplugged for a long time, there is static electricity between the plugs, and the plugs fit tightly. The safety device cannot be unplugged after multiple attempts without a specific clamping tool. This delays the operation progress and delays the working time. In addition, when the safety device is not unplugged with a special tool, there is a certain amount of wear on the appearance of the safety device, which may affect the degree of fit when it is inserted again, affecting the normal function of the insurance.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] like Figure 1-3 As shown, this embodiment provides an embodiment of a plug-in and pull-out handheld tool for a plug-in low-voltage arrester. In this embodiment, the handheld tool comprises a jacket body 1, and the jacket body 1 is used to be detachably connected to a handle for plugging and pulling;

[0026] See Figure 3As shown, at least two groups of clamping components 4, both groups of clamping components 4 include a clamping claw 41, wherein the clamping claw 41 is made of stainless steel or aluminum alloy material and will not rust; the two groups of clamping components 4 are provided with anti-skid patterns 45 for clamping the plug-in low-voltage arrester at one end close to each other, and the anti-skid patterns 45 need to be blunt at an acute angle, and the two groups of clamping components 4 are provided with a second mounting through hole 42 for connecting with the jacket body 1 at one end away from the anti-skid patterns 45, and the clamping components 4 and the jacket body 1 are detachably connected;

[0027] like Figure 2 As shown, a bearing body 2 is rotatably installed in the jacket body 1, and the bearing body 2 is located between two groups of clamping components 4. A sliding block 3 is installed on the outer ring of the bearing body 2, and the sliding block 3 is located between the two groups of clamping components 4. The opening angle of one end of the two clamping jaws 41 is controlled by the setting of the sliding block 3. The maximum opening between the two groups of clamping jaws 41 along the retaining spring pin is 69.16 mm, and the minimum opening is 13.17 mm.

[0028] The sliding block 3 is detachably connected to the bearing body 2 , and the sliding block 3 is located in the gap between the two groups of clamping components 4 .

[0029] Preferably, the jacket body 1 is a "C"-shaped structure, and bolt mounting holes 13 are provided at both ends of the opening of the jacket body 1. The bolt mounting holes 13 are detachably connected to the handles for plugging and unplugging. The handles for plugging and unplugging are made of high-strength polyethylene material, which can meet the requirements of lifting a maximum weight of 50KG. Therefore, the handheld tooling prepared in this embodiment can not only be used as a special tool for pulling out insurance, but also can be used for clamping and extracting other heavy objects;

[0030] One side of the jacket body 1 is provided with an installation cavity 11 for assembling with the clamping assembly 4. The sliding block 3 is a cylindrical structure, and the thickness of the sliding block 3 is adapted to the inner diameter of the installation cavity 11. Through the setting of the installation cavity 11, the sliding block 3 will be restricted from moving along the inner wall of the installation cavity 11, so that the sliding block 3 can only move horizontally under the guidance of the inner wall of the installation cavity 11 and the guide track 44, thereby adjusting the distance of the two jaws 41 opened along the rotation of the retaining pin. If the distance between the ends of the two jaws 41 without the anti-slip grooves 45 increases, the distance between the other ends of the two jaws 41, that is, the ends with the anti-slip grooves 45, decreases, and vice versa, thereby clamping lightning rods of different sizes.

[0031] Furthermore, a first through hole penetrating the jacket body 1 is formed on the side wall of the mounting cavity 11, and the bearing body 2 includes a handle mounting portion 21, a connecting portion 22 and a threaded portion 23, wherein the connecting portion 22 is installed in the first through hole, and a limiting ring is provided on the outer ring of the bearing body 2 for limiting the installation position of the connecting portion 22 in the first through hole, so that the connecting portion 22 can limit the horizontal movement distance in the first through hole and perform in-situ rotational movement.

[0032] Furthermore, the end of the handle mounting portion 21 is used to mount a hexagonal nut, and a mounting portion for mounting a plum blossom square handle is provided between the handle mounting portion 21 and the connecting portion 22, wherein the plum blossom square handle is not shown in the figure;

[0033] The outer ring of the threaded portion 23 is provided with a threaded groove, and the sliding block 3 is installed by sleeve installation with the outer ring of the threaded portion 23 through the corresponding threaded groove. Furthermore, under the rotation action of the threaded groove and the limiting action of the guide rail 44 and the installation cavity 11, the sliding block 3 is moved horizontally left and right along the connecting portion 22, wherein the left and right movement direction is related to the rotation direction of the plum blossom square mouth.

[0034] It should be noted that the formation of the threaded notches is a common application of the prior art, and the detailed structure thereof will not be described in detail in this embodiment, nor will it be shown in drawings.

[0035] Furthermore, anti-slip grooves 45 are arranged on the side of one end of the clamping jaws 41, and the anti-slip grooves 45 are used to increase the friction force of the clamping end of the clamping jaws 41 so that the lightning arrester can be firmly clamped. The two groups of clamping jaws 41 are away from the anti-slip grooves 45 and are close to each other. The side surfaces are both provided with arc grooves 43 adapted to be installed with the sliding block 3, wherein the maximum distance between the two arc grooves 43 is greater than the maximum diameter of the sliding block 3, and guide rails 44 are provided on both sides of each arc groove 43, and the cross-sectional radius of the guide rails 44 is adapted to the thickness of the sliding block 3.

[0036] Furthermore, a mounting through hole 12 corresponding to the position of the mounting through hole 2 42 is provided on the jacket body 1, and the clamping assembly 4 is assembled with the jacket body 1 through a retaining spring pin between the mounting through hole 12 and the mounting through hole 2, and at the same time, the two clamping jaws 41 are rotatably arranged in the mounting cavity 11 relative to the retaining spring pin installed on themselves.

[0037] Two groups of clamping components 4 are installed in the jacket body 1 of the utility model, and the plug-in lightning rod is firmly and non-sliply clamped by setting the anti-skid pattern 45 at one end of the two groups of clamping components 4; the clamping component 4 is assembled with the jacket body 1 by setting the second installation through hole 42 and the first installation through hole 12, and at the same time, the installation cavity 11 is opened to facilitate the two clamping claws 41 to rotate along the retaining spring pin in the installation cavity 11, and the size of the opening at one end of the two clamping claws 41 is adjusted by setting the bearing body 2 and the sliding block 3, so as to adapt to the clamping and fixing of lightning arresters of different sizes, thereby improving the practicality of the overall tooling and being convenient for operation on site. Lightning rods of the same model and specification can be clamped and plugged, and the operation flexibility is high. Multiple types of plug-in lightning rods only need one tool to complete the plug-in and pull-out operations. Specifically, when the plug-in and pull-out operations are carried out, the anti-slip grooves 45 are clamped corresponding to the lightning rod. If the lightning rod is small and the two anti-slip grooves 45 do not contact the lightning rod, the distance between the anti-slip grooves 45 at the ends of the two clamping claws 41 should be adjusted to make the distance between the two smaller. At this time, the plum blossom square handle is turned to rotate the bearing body 2. While the bearing body 2 is rotating, the sliding block 3 is guided horizontally along the guide track 44 to move the sliding block 3 relative to the guide rail 44. Figure 1 The position shown is moved to the left, thereby stretching the end of the clamping claw 41 without the anti-slip pattern 45, thereby reducing the distance of the end with the anti-slip pattern 45, completing the support of the lightning rod, and pulling the handle (not shown in the figure) to pull the plug-in lightning arrester out from the original installation position.

[0038] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
