Description

Technical Field

[0001] The invention belongs to the technical field of parallel groove wire clamp insulation sheaths, and in particular relates to a parallel groove wire clamp insulation sheath for live working and a use method thereof. Background Art

[0002] The insulating sheath of the parallel groove wire clamp is used to cover the parallel groove wire clamp. Therefore, when the distribution line is energized, the possibility of the existence of exposed live parts is eliminated, which can effectively improve the safe operation level of the line.

[0003] The inventors found that during live working, when workers install insulating sheaths while wearing triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves, they cannot smoothly operate the buckles on the insulating sheaths, especially when multiple insulating sheaths are installed on the parallel groove wire clamps in sequence. The inconvenience of operating the buckles reduces the working efficiency. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes an insulating sheath of a parallel groove wire clamp for live working and a method of use. A buckle connection method is adopted between the first insulating shell and the second insulating shell of the insulating sheath of the parallel groove wire clamp, and the traditional buckle connection method is abandoned. Instead, a buckle connection method of loose lock and toothed belt is adopted; at the same time, the present invention optimizes the installation position of fixing components such as loose lock and toothed belt. The loose lock and toothed belt are respectively installed at the bottom of the upper insulating sheath and the lower insulating sheath and are parallel to the bottom. Therefore, the operator does not need to change the direction of force during the installation process. It only needs to put the upper insulating sheath and the lower insulating sheath together to achieve the firm installation of the insulating sheath of the parallel groove wire clamp. The present invention is simple to operate. When the operator installs the insulating sheath with triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves, the insulating sheath can be closed and opened smoothly, thereby improving the working efficiency.

[0005] In order to achieve the above-mentioned object, in a first aspect, the present invention provides an insulating sheath of a parallel groove wire clamp for live working, which adopts the following technical solution:

[0006] An insulating sheath of a parallel groove wire clamp for live working, comprising a first insulating shell and a second insulating shell connected to each other;

[0007] The first insulating housing is provided with a toothed belt, and the second insulating housing is provided with a releasable lock buckle. The toothed belt and the releasable lock buckle are respectively installed at the bottom of the first insulating housing and the second insulating housing and are parallel to the bottom; the releasable lock buckle includes a handle, a tooth cavity and a guide plate, the handle is elastically connected to the releasable lock buckle, including an operating handle and a clamping head arranged at the bottom of the tooth cavity, the tooth cavity is used to allow the toothed belt to enter and exit, and the guide plate is used to guide and control the direction of the toothed belt to enter and exit. The toothed belt has a clamping tooth on one side facing the outside of the first insulating housing, and a smooth design on the one side facing the inside of the first insulating housing.

[0008] When the operator is closing the first insulating shell and the second insulating shell, the operator drives the toothed belt to pass into the toothed cavity, and the clamping head engages with the clamping teeth on the toothed belt to achieve a secure installation of the insulating sheath; by toggling the handle, the clamping head is driven to separate from the clamping teeth on the toothed belt, thereby achieving the opening of the first insulating shell and the second insulating shell.

[0009] Furthermore, the first insulating shell and the second insulating shell are both configured as stepped shells.

[0010] Alternatively, the first insulating shell and the second insulating shell are both configured as arc shells.

[0011] Furthermore, a guide head is provided at one end of the toothed belt away from the first insulating shell; the guide head is a conical head or a trapezoidal head.

[0012] Furthermore, a step structure is provided on both the first insulating shell and the second insulating shell; on the first insulating shell, the end of the step structure with a smaller size is close to the second insulating shell; on the second insulating shell, the end of the step structure with a smaller size is close to the first insulating shell.

[0013] Furthermore, the toothed belt and the releasable lock buckle are respectively arranged at a middle position of the stepped structure on the first insulating shell and a middle position of the stepped structure on the second insulating shell.

[0014] Furthermore, wiring holes are provided on the first insulating shell and the second insulating shell.

[0015] Furthermore, the width D of the tooth block on the toothed belt is:

[0016] D=D 标 +γD1-βD2

[0017] Among them, D 标 is the width of the gear block under standard conditions; D1 is the increase in the load-bearing capacity requirement; D2 is the decrease in the sealing requirement; γ and β are weights.

[0018] In order to achieve the above-mentioned purpose, in a second aspect, the present invention also provides a method for using an insulating sheath of a parallel groove wire clamp for live working, which adopts the following technical solution:

[0019] A method for using a parallel groove wire clamp insulating sheath for live working, using the parallel groove wire clamp insulating sheath for live working as described in the first aspect, the working method of the present invention comprises the following steps:

[0020] S1: The operator closes the first insulating housing and the second insulating housing, during which the toothed belt is driven to pass through the toothed cavity, and the clamping head is engaged with the clamping teeth on the toothed belt to achieve a firm fixation of the insulating sheath of the parallel groove wire clamp;

[0021] S2: The first insulating shell and the second insulating shell are opened by pulling the handle to separate the clamping head from the tooth block on the toothed belt.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The insulating sheath of a parallel groove wire clamp for live working and the method of use of the present invention adopt a buckling method of a loose lock and a toothed belt to cooperate and fix, and optimize the installation position of the fixing component (loose lock and toothed belt). In terms of installation implementation, the traditional insulating sheath of the parallel groove wire clamp needs to first put the upper insulating sheath and the lower insulating sheath together, and then change the force direction to use the snap connection. In contrast, the present invention only requires the operator to put the upper insulating sheath and the lower insulating sheath together to achieve the firm installation of the insulating sheath of the parallel groove wire clamp, that is, the present invention has the advantage of simple operation.

[0024] 2. The one-time installation success rate of the present invention can reach 100%. According to statistical data in actual applications, the one-time installation success rate of the traditional parallel groove wire clamp insulation sheath in live working scenarios is less than 30%, and the final installation success rate is less than 79%.

[0025] 3. Under the premise of the same workload, compared with the traditional parallel groove wire clamp insulation sheath, the operation time can be reduced by more than 80% after adopting the present invention, which greatly improves the operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0036] Embodiment 1:

[0037] The insulating sheath of the parallel groove wire clamp is used to cover the parallel groove wire clamp. When the distribution line is energized, it eliminates the possibility of the existence of exposed live parts and can effectively improve the safe operation level of the line.

[0038] The traditional parallel groove wire clamp insulation sheath is not designed for live working scenarios. Therefore, during live working, when workers install the insulation sheath while wearing triple protection of wire gloves, insulation gloves and sheepskin puncture-proof gloves, the operation is more difficult. Moreover, even in ordinary installation scenarios, the traditional parallel groove wire clamp insulation sheath has a relatively low installation success rate due to factors such as deformation during transportation.

[0039] In response to the above problems, Figure 1 and Figure 2 As shown, this embodiment provides an insulating sheath of a parallel groove wire clamp for live working, comprising a first insulating shell 1 and a second insulating shell 2 connected to each other;

[0040] A toothed belt 3 is provided on the first insulating shell 1, and a releasable lock buckle 4 is provided on the second insulating shell 2; the releasable lock buckle 4 includes a tooth cavity 404 opened on the lock buckle mounting portion 401 for accommodating the toothed belt 3, and a pressing portion 402 elastically connected to the releasable lock buckle 4; the releasable lock buckle 4 also includes a guide plate 403 and a clamping head 405.

[0041] During the closing operation, the toothed belt 3 is directly inserted into the tooth cavity 404, and the clamping head 405 is clamped with the tooth block 301 on the toothed belt 3 to achieve the closing of the first insulating shell 1 and the second insulating shell 2; by toggling the pressing part 402, the clamping head 405 is driven to separate from the tooth block 301 on the toothed belt 3 to achieve the opening of the first insulating shell 1 and the second insulating shell 2; the operation is simple, and the operator can smoothly close and open the insulating sleeve when installing the insulating sleeve with triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves, thereby improving the working efficiency.

[0042] Optionally, the insulating sheath of the parallel groove wire clamp in this embodiment is made of silicone rubber. It can be understood that two groups of connection points are set between the first insulating shell 1 and the second insulating shell 2, and each group of connection points is connected by rubber material, which can allow the first insulating shell 1 and the second insulating shell 2 to rotate relative to each other to achieve merging and opening.

[0043] like Figure 1 As shown, in this embodiment, the first insulating shell 1 and the second insulating shell 2 are both configured as stepped shells, so that the cavity after the first insulating shell 1 and the second insulating shell 2 are closed is adapted in shape to the parallel groove wire clamp.

[0044] The guide piece 403 enables the toothed belt 3 to be smoothly inserted into the tooth cavity 404 . The tooth cavity 404 can be understood as a through hole.

[0045] In some embodiments, in non-electrical working conditions, operators do not need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sleeve barehanded; and the overall structure of the insulating sleeve is not deformed; the toothed belt 3 can be accurately and quickly inserted into the tooth cavity 404 through the guide plate 403.

[0046] In some embodiments, in non-electrical working conditions, operators do not need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath barehanded; and the overall structure of the insulating sheath is deformed during transportation, especially the connection; at this time, the operator can still accurately and quickly insert the toothed belt 3 into the tooth cavity 404 through the guide plate 403, because the toothed belt 3 has a certain length and is more adaptable, which can reduce the impact of deformation on the connection operation. At this time, the problem of low installation success rate caused by factors such as deformation of the insulating sheath of the traditional parallel groove wire clamp is solved.

[0047] In some embodiments, in non-electrical working conditions, the operator only wears wire gloves to install the insulating sheath by hand; and the overall structure of the insulating sheath is not deformed; if a traditional insulating sheath is used, the wire gloves will also cause certain difficulties in operation, because the traditional insulating sheath connection adopts a snap-on form, which is difficult to grasp and align, while in this embodiment, the toothed belt 3 can be accurately and quickly inserted into the tooth cavity 404 through the guide plate 403, thereby improving the operating efficiency.

[0048] In some embodiments, in non-electrical working conditions, operators only wear wire gloves to install the insulating sheath by hand; and the overall structure of the insulating sheath is deformed during transportation, especially at the connection; at this time, if a traditional insulating sheath is used, the wire gloves will also cause certain difficulties in operation. Not only is the operation inconvenient, but it is also difficult to align the connection due to deformation at the bayonet. Through the settings in this embodiment, the operator can accurately and quickly insert the tooth belt 3 into the tooth cavity 404 through the guide piece 403. Because the tooth belt 3 has a certain length, the influence of deformation on the connection operation can be reduced. At this time, the problem of low installation success rate caused by factors such as deformation of the insulating sheath of the traditional parallel groove wire clamp is solved.

[0049] In some embodiments, when working with electricity, workers need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath; although the overall structure of the insulating sheath is not deformed, due to the interference of the triple protection, it is difficult for workers to insert the clamp head 405 on the traditional insulating sheath into the clamp hole, while the toothed belt 3 in this embodiment can be accurately and quickly inserted into the tooth cavity 404 through the guide plate 403, thereby improving operating efficiency.

[0050] In some embodiments, when working with electricity, operators need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath, and the overall structure of the insulating sheath is deformed during transportation, especially the connection part is deformed; at this time, if a traditional insulating sheath is used, not only is it difficult for the operator to insert the clamp 405 on the traditional insulating sheath into the clamp hole due to the interference of the triple protection, but the deformation also causes the clamp 405 and the hole to be misaligned, further increasing the difficulty of operation; at this time, through the setting in this embodiment, the operator can accurately and quickly insert the toothed belt 3 into the tooth cavity 404 through the guide plate 403. At the same time, because the toothed belt 3 has a certain length, the influence of deformation on the connection operation can be reduced, thereby solving the problem of triple protection interference and the problem of low installation success rate caused by factors such as deformation of the insulating sheath of the parallel groove wire clamp.

[0051] like Figure 4 As shown, a guide head 302 is provided at one end of the toothed belt 3 away from the first insulating shell 1; the guide head 302 is a conical head or a trapezoidal head.

[0052] Specifically, in some embodiments, when working with electricity, the operator needs to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath, and the overall structure of the insulating sheath is deformed during transportation, especially the connection part is deformed; at this time, if a traditional insulating sheath is used, not only because of the interference of the triple protection, it is difficult for the operator to insert the clamp head 405 on the traditional insulating sheath into the clamp hole, but also the deformation causes the clamp head 405 and the clamp hole to be misaligned, further increasing the difficulty of the connection operation; at this time, through the setting in this embodiment, the operator can use the cooperation of the guide head 302 and the guide plate 403 to accurately and quickly insert the toothed belt 3 into the tooth cavity 404, thereby improving the installation success rate and efficiency.

[0053] like Figure 4 As shown, a step structure 101 is provided on the first insulating shell 1 and the second insulating shell 2; on the first insulating shell 1, the end of the step structure 101 with a smaller size is close to the second insulating shell 2; on the second insulating shell 2, the end of the step structure 101 with a smaller size is close to the first insulating shell 1.

[0054] Specifically, on the first insulating shell 1, the end with a smaller step structure size is close to the second insulating shell 2; on the second insulating shell 2, the end with a smaller step structure size is close to the first insulating shell 1; the occurrence of openings at both ends of the first insulating shell 1 and the second insulating shell 2 can be reduced, thereby ensuring the closing effect.

[0055] like Figure 4 As shown, the toothed belt 3 and the releasable buckle 4 are respectively arranged at the middle position of the stepped structure 101 on the first insulating shell 1 and the middle position of the stepped structure 101 on the second insulating shell 2 through the toothed belt mounting portion 102 and the buckle mounting portion 401, respectively.

[0056] Specifically, the traditional insulating sheath has two symmetrical buckles at the connection, which makes the operation difficult. However, in the present embodiment, on the basis of setting a stepped structure 101 to improve the connection effect, only a toothed belt 3 and a releasable lock buckle 4 are set in the middle position of the insulating sheath, which greatly saves the operation process and reduces the difficulty of operation.

[0057] In some embodiments, in non-electrical working conditions, operators do not need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath barehanded; and the overall structure of the insulating sheath is not deformed; if a traditional insulating sheath is used, the connection operation needs to be repeated twice, while using the insulating sheath in this embodiment, while ensuring the connection effect, only one connection operation needs to be performed, which greatly improves the operating efficiency.

[0058] In some embodiments, in non-electrical working conditions, operators do not need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sleeve barehanded; and the overall structure of the insulating sleeve is deformed during transportation, especially the connection; at this time, if a traditional insulating sleeve is used, not only is it necessary to repeat the connection operation twice, but the deformed insulating sleeve, the clamp head 405 and the clamp hole cannot be well connected, which greatly affects the operating efficiency. By using the insulating sleeve in this embodiment, not only can the docking problem caused by deformation be compensated by the length of the toothed belt 3, but also only one connection operation is required, which greatly improves the operating efficiency.

[0059] In some embodiments, in a non-electrical working condition, the operator only wears wire gloves to install the insulating sleeve by hand; and the overall structure of the insulating sleeve is not deformed; if a traditional insulating sleeve is used, not only does it need to be repeated twice to connect, but the wire gloves will also interfere with the operator's operation of the clamping head 405 and the clamping hole; while using the insulating sleeve in this embodiment, on the basis of ensuring the connection effect, only one connection operation is required. At the same time, the functions of the toothed belt 3, the guide head 302 and the guide plate 403 can quickly realize the connection operation, greatly improving the operating efficiency.

[0060] In some embodiments, in a non-electrical working condition, the operator only wears wire gloves to install the insulating sleeve by hand; and the overall structure of the insulating sleeve is deformed during transportation, especially the connection part; at this time, not only will the wire gloves interfere with the operator's operation of the clamping head 405 and the clamping hole, but also, the deformed insulating sleeve, its clamping head 405 and the clamping hole cannot be well connected, which greatly affects the operating efficiency. By using the insulating sleeve in this embodiment, on the basis of ensuring the connection effect, not only only one connection operation is required, but also the connection problem caused by the deformation can be compensated by the length of the toothed belt 3, which greatly improves the operating efficiency.

[0061] In some embodiments, when working with electricity, the operator needs to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath; although the overall structure of the insulating sheath is not deformed, if a traditional insulating sheath is used, not only will the interference of the triple protection increase the difficulty of operation, but also the connection needs to be repeated twice. However, when using the insulating sheath in this embodiment, while ensuring the connection effect, only one connection operation is required, which greatly improves the operating efficiency.

[0062] In some embodiments, when working with electricity, operators need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath, and the overall structure of the insulating sheath is deformed during transportation, especially the connection part is deformed; at this time, if a traditional insulating sheath is used, not only is it difficult for the operator to insert the clamp head 405 on the traditional insulating sheath into the clamp hole due to the interference of the triple protection, but the deformation causes the clamp head 405 and the hole to be misaligned, which further increases the difficulty of operation. The two operations increase the connection operation time; at this time, through the setting in this embodiment, not only can the operator accurately and quickly insert the toothed belt 3 into the tooth cavity 404 through the guide plate 403, but also because the toothed belt 3 has a certain length, the influence of deformation on the connection operation can be reduced, the interference operation of the triple protection is solved, and the installation success rate and efficiency are improved.

[0063] like Figure 1 As shown, the first insulating housing 1 and the second insulating housing 2 are both provided with wiring holes 5 for matching with parallel groove wire clamps.

[0064] It should be noted that, in some embodiments, only one insulating sheath needs to be installed at a time, and the insulating sheath is not deformed. At this time, the advantage of using the insulating sheath in this embodiment is only reflected in the low operating requirements for the toothed belt 3 and the releasable lock 4, because the guide head 302 and the guide plate 403, etc., can realize the rapid alignment and clamping of the toothed belt 3 and the releasable lock 4.

[0065] In some embodiments, only one insulating sheath needs to be installed at a time, and the insulating sheath is deformed. At this time, the insulating sheath in this embodiment is used. The advantage is not only that the toothed belt 3 and the releasable buckle 4 can be quickly aligned and snapped together, but also that the toothed belt 3 has a certain length, which can compensate for the difficulty in docking caused by deformation.

[0066] In some embodiments, multiple insulating sheaths need to be installed at a time, and the insulating sheaths are not deformed. At this time, the insulating sheaths in this embodiment are used. The advantage is that the toothed belt 3 and the releasable buckle 4 can be quickly aligned and snapped together, and the connection can be completed by only operating sequentially, which greatly improves the working efficiency.

[0067] In some embodiments, multiple insulating sheaths need to be installed at a time, and the insulating sheaths are deformed. At this time, the insulating sheaths in this embodiment can achieve rapid alignment and clamping of the toothed belt 3 and the releasable buckle 4, and the connection can be completed by only operating sequentially. In addition, the toothed belt 3 has a certain length, which can compensate for the problem of difficult docking due to deformation, thereby greatly improving work efficiency.

[0068] In some embodiments, the insulating sheath needs to be recycled. When performing non-electrical operations, the advantage is mainly reflected in that using a traditional insulating sheath requires two operations at two connections, while using the insulating sheath in this embodiment only requires operations at the middle connection.

[0069] In some embodiments, the insulating sheath needs to be recycled. When performing live work, the advantage is not only that the use of traditional insulating sheaths requires two operations at two connections, while the use of the insulating sheath in this embodiment only requires operation at the middle connection; the advantage is also reflected in that the operator needs to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to disassemble the insulating sheath. The clamp 405 and the clamp hole on the traditional insulating sheath are not easy to operate, but when using the insulating sheath in this embodiment, the operator only needs to operate the pressing part 402 with the help of the outermost sheepskin puncture-proof gloves to separate the clamp 405 from the tooth block 301. At this time, the toothed belt 3 can be smoothly taken out of the tooth cavity 404 to complete the disassembly of the insulating sheath, which greatly ensures the working efficiency.

[0070] like Figure 6As shown, on the basis of a certain length of the toothed belt 3, when the width of the tooth block 301 is small, it is beneficial to improve the sealing degree after the first insulating housing 1 and the second insulating housing 2 are closed, but its load-bearing capacity is small and the design and processing are difficult. When the tooth block 301 is large, the load-bearing capacity is large and the design and processing are easy, but it is not conducive to improving the sealing degree after the first insulating housing 1 and the second insulating housing 2 are closed. In order to solve such problems, in some embodiments, the width of the tooth block 301 is optimized, and the specific width D of the tooth block 301 is:

[0071] D=D 标 +γD1-βD2

[0072] Among them, D 标 is the width of the tooth block 301 under standard conditions, which can be formulated according to actual conditions; D1 is the increase in the load-bearing capacity requirement, which can be formulated according to the load-bearing capacity requirement, for example, for every increase of 1N in the load-bearing capacity requirement, the value of D1 increases by 0.2mm; D2 is the reduction in the sealing requirement, which can be set and adjusted according to historical data or actual conditions; γ and β are weights, for example, γ=0.7, β=0.3.

[0073] Through the above arrangement, when determining the width of the tooth block 301, the two requirements of sealing and load-bearing requirements are considered, and on the basis of ensuring the load-bearing capacity and processing convenience, the sealing degree after the first insulating shell 1 and the second insulating shell 2 are closed is guaranteed to the greatest extent.

[0074] With the insulating sheath in this embodiment, the one-time installation success rate can be close to 100%. According to the statistical data in actual applications, the one-time installation success rate of the traditional parallel groove wire clamp insulating sheath in the live working scene is less than 30%, and the final installation success rate is less than 79%. In terms of installation implementation, the traditional parallel groove wire clamp insulating sheath needs to first put the upper insulating sheath and the lower insulating sheath together, and then change the force direction to make the buckle connection. In contrast, the insulating sheath in this embodiment only requires the operator to put the first insulating shell 1 and the second insulating shell 2 together to achieve the firm installation of the parallel groove wire clamp insulating sheath.

[0075] Under the premise of the same workload, compared with the traditional parallel groove wire clamp insulating sheath, after adopting the insulating sheath in this embodiment, the operation time can be reduced by more than 80%, which greatly improves the operation efficiency.

[0076] Embodiment 2:

[0077] like Figure 5 As shown, this embodiment provides an insulating sheath of a parallel groove wire clamp for live working; the only difference from Embodiment 1 is that the first insulating shell 1 and the second insulating shell 2 are both configured as arc shells.

[0078] In some embodiments, when working with electricity, workers need to wear triple protection of wire gloves, insulating gloves and sheepskin puncture-proof gloves to install the insulating sheath, and the overall structure of the insulating sheath is deformed during transportation, especially the connection part is deformed; at this time, if a traditional insulating sheath or a stepped insulating sheath is used, not only is it difficult for the staff to insert the clamp 405 on the traditional insulating sheath into the clamp hole due to the interference of the triple protection, but the deformation causes the clamp 405 and the hole to be misaligned, which further increases the difficulty of operation. The two operations also increase the connection operation time; at this time, through the setting in this embodiment, not only can the operator accurately and quickly insert the toothed belt 3 into the tooth cavity 404 through the guide plate 403, but because the toothed belt 3 has a certain length, the influence of deformation on the connection operation can be reduced, solving the problem of triple protection interference. At the same time, when a stepped shell is used, it is necessary to make the shell and the parallel groove clamp absolutely compatible before installation and connection, which increases the operation process and difficulty. In the present embodiment, because the first insulating shell 1 and the second insulating shell 2 are both configured as arc shells, it is not necessary for the shell to be absolutely compatible with the parallel groove clamp before installation and connection. After the toothed belt 3 is inserted into the tooth cavity 404, the first insulating shell 1 and the second insulating shell 2 are squeezed to achieve a tight connection between the first insulating shell 1 and the second insulating shell 2, which greatly reduces the operation difficulty.

[0079] Embodiment 3:

[0080] The present embodiment provides a method for using an insulating sheath of a parallel groove wire clamp for live working, using the insulating sheath of the parallel groove wire clamp for live working as described in Example 1, including: during installation, as the operator brings the first insulating shell 1 and the second insulating shell 2 together, the toothed belt 3 can be inserted into the tooth cavity 404, and the clamping head 405 is clamped with the tooth block 301 on the toothed belt 3, so that the first insulating shell 1 and the second insulating shell 2 can be closed and firmly installed; by toggling the pressing part 402, the clamping head 405 is driven to separate from the tooth block 301 on the toothed belt 3, so that the first insulating shell 1 and the second insulating shell 2 can be opened.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
