DETAILED DESCRIPTION

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to be able to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] The live working insulating rods in the prior art also have deficiencies in stability, convenience and operational flexibility. In addition, the existing live working insulating rods often cannot meet the high requirements for stability in aerial work, and most of them are made of heavy materials, which increases the overall weight of the tool and affects the working efficiency. In addition, the design of the clamping mechanism usually does not have good adaptability, resulting in the need for operators to frequently adjust the tools when performing different tasks, which increases the complexity of the operation.

[0024] See also Figure 1 , which shows the preferred structure of the lightweight live working insulating rod provided by the embodiment of the present invention. As shown in the figure, the live working insulating rod comprises: a telescopic insulating rod body 1, a clamping mechanism 2 and a locking mechanism 3; wherein, The telescopic insulating rod body 1 is used for live working. Specifically, the telescopic insulating rod body 1 is used for live working and can be telescopically moved to reduce the storage space required for the device, and is convenient to carry to the working area. The telescopic insulating rod body 1 can not only ensure the safety of the working and prevent the risk of electric shock, but also improve the convenience of the device through the telescopic function, reduce the trouble of carrying and storing, and enable the operator to easily carry and access the device.

[0025] The clamping mechanism 2 is arranged at the telescopic end of the telescopic insulating rod body 1 (such as Figure 1 The top end shown in the figure) is used to clamp onto the workpiece to be clamped (not shown in the figure) to clamp the workpiece to be clamped. Specifically, the clamping mechanism 2 is arranged at the telescopic end of the telescopic insulating rod body 1, and is used to clamp the object to be operated, that is, the workpiece to be clamped, so as to complete the operations of pulling and closing switches, adjusting lines, removing foreign objects, and installing or replacing equipment. The setting of the clamping mechanism 2 improves the flexibility and efficiency of the operation. Through simple operations, the operator can adjust the clamping force, and at the same time can adapt to the use height of the telescopic insulating rod body 1, thereby improving the portability of the device.

[0026] The locking mechanism 3 is arranged on the telescopic insulating rod body 1, and is used to lock the telescopic insulating rod body 1 when the telescopic insulating rod body 1 is telescoped to the corresponding length. Specifically, it is arranged on the outside of the telescopic insulating rod body 1, and is used to lock the telescopic insulating rod body 1 when it is in the process of being extended, so as to adjust the use state of the telescopic insulating rod body 1. The setting of the locking mechanism 3 ensures that during the high-altitude operation, the telescopic insulating rod body 1 will not slide or retract when in use, thereby improving the safety and stability of the operation, and allowing the operator to concentrate on the operation in a complex working environment without worrying about the instability of the tool. In this embodiment, there can be multiple locking mechanisms 3, so as to perform locking of different telescopic lengths.

[0027] Continue to see Figures 1 to 4 The telescopic insulating rod body 1 comprises: a first insulating rod 11 and a second insulating rod 12; wherein the second insulating rod 12 is sleeved inside the first insulating rod 11, and the second insulating rod 12 is axially extending along the first insulating rod 11 (such as Figure 1 The first insulating rod 11 is connected to the first insulating rod 11 in a slidable and rotatable manner for adjusting the telescopic length and limiting the extended end.

[0028] Specifically, the first insulating rod 11 is slidably connected to the inside of the second insulating rod 12, and the second insulating rod 12 is coaxially arranged with the first insulating rod 11, and the two can slide and rotate relative to each other. Through the relative sliding between the two, telescopic movement can be achieved, and through the relative rotation between the two, self-retraction between the two can be avoided, and position limiting can be achieved. Among them, the first insulating rod 11 and the second insulating rod 12 are both hollow insulating rod bodies. In this example, the bottom end of the first insulating rod 11 can be provided with a bottom support plate 112, which is used to support the second insulating rod 12 inside, etc., to prevent the second insulating rod 12 from moving down from the bottom of the first insulating rod 11 and falling off from the first insulating rod 11. Among them, the first insulating rod 11 and the second insulating rod 12 can be made of aramid resin composite materials. The aramid resin composite material has excellent tensile strength and bending strength, can withstand large external forces without deformation or fracture, and can still maintain good mechanical properties and structural stability in a high temperature environment. Finally, it also has good electrical insulation performance. By using aramid resin composite materials, the weight of the overall structure of the device can be reduced, the operation of the operator is easier, and the operation efficiency is improved.

[0029] In this embodiment, a guide groove 111 is provided on the inner wall of the first insulating rod 11, and a guide block 121 is provided on the outer wall of the second insulating rod 12, which is slidably arranged in the guide groove 111, and is used to limit and guide the sliding and rotation of the second insulating rod 12. The guide block 121 is adapted to the guide groove 111 so as to limit and guide the sliding and rotation of the second insulating rod 12. The second insulating rod 12 can slide vertically and rotate inside the first insulating rod 11 through the limit of the guide block 121, and can prevent the second insulating rod 12 and the first insulating rod 11 from falling off in the radial direction. In this embodiment, there can be two guide grooves 111 and two guide blocks 121, so as to improve the stability of the relative movement between the first insulating rod 11 and the second insulating rod 12. In this embodiment, the locking mechanism 3 can be set at the position corresponding to the guide groove 111. When the guide block 121 slides to the corresponding position along the guide groove 111, the locking mechanism 3 can lock the guide block 121, thereby locking the second insulating rod 12 at the corresponding height.

[0030] Continue to see Figure 6The top of the second insulating rod 12 has a top support plate 122 for supporting the top clamping mechanism 2.

[0031] Continue to see Figure 3 and Figure 4 The guide groove 111 includes: a telescopic slide groove 1111, a spiral groove 1112 and a positioning groove 1113; wherein the telescopic slide groove 1111, the spiral groove 1112 and the positioning groove 1113 are formed from the fixed end of the first insulating rod 11 (such as Figure 3 The bottom end shown in FIG. 1 ) is connected to the connecting end of the first insulating rod 11 (as shown in FIG. Figure 3 The top end shown in the figure is arranged in sequence, and the telescopic slide groove 1111 and the positioning groove 1113 are connected by a spiral groove 1112. The telescopic slide groove 1111 is used to guide the telescopic movement of the second insulating rod 12 along the axial direction of the first insulating rod 11, and the spiral groove 1112 is used to guide the rotation of the second insulating rod 12 relative to the first insulating rod 11.

[0032] Specifically, the telescopic slide groove 1111 is a linear slide groove arranged along the axial direction of the first insulating rod 11, the positioning groove 1113 is a groove structure adapted to the guide block 121, and there is a spacing between the positioning groove 1113 and the telescopic slide groove 1111, and the two are connected through the spiral groove 1112. The telescopic slide groove 1111, the spiral groove 1112 and the positioning groove 1113 all provide space for the guide block 121 to move. Through the cooperation of the telescopic slide groove 1111 and the spiral groove 1112, the second insulating rod 12 can be moved vertically and then moved. Rotation; in this embodiment, the spiral groove 1112 and the positioning groove 1113 are both placed at the connecting end of the first insulating rod 11, so that after the second insulating rod 12 slides along the telescopic slide groove 1111 with the guide block 121 to the connecting end of the first insulating rod 11, in order to prevent the second insulating rod 12 from retracting or sliding downward under the action of gravity, the guide block 121 can slide along the spiral groove 1112, thereby realizing the relative rotation between the first insulating rod 11 and the second insulating rod 12, so that the guide block 121 can slide to the positioning groove 1113. In this embodiment, the positioning groove 1113 can be an open groove at both ends, and the bottom opening is connected to the spiral groove 1112, so that the guide block 121 can slide from the spiral groove 1112 to the positioning groove 1113. The top opening can facilitate the guide block 121 to continue to move upward, realize the separation between the first insulating rod 11 and the second insulating rod 12, and then realize the disassembly between the two, so that they can be removed for storage or replacement, which improves the storage options of the device, that is, it can be retracted for storage, or disassembled for storage; of course, when reinstalling, the guide block 121 can also rotate and slide downward from the positioning groove 1113 to the telescopic slide groove 1111. Among them, transition parts are provided between the telescopic slide groove 1111 and the spiral groove 1112, and between the spiral groove 1112 and the positioning groove 1113, so that the guide block 121 can slide smoothly.

[0033] In this embodiment, different environments will be encountered during the use of lightweight live working insulating rods, so it is necessary to work in different environments, which can easily cause damage to the rod itself. In order to avoid insulation failure, the second insulating rod 12 and the first insulating rod 11 can be maintained by dismantling the second insulating rod 12 and the first insulating rod 11, and during the maintenance process, another corresponding rod can be replaced and used, and this operation can also be replaced according to the size of the clamp required, so that it can clamp objects of different sizes and perform operations.

[0034] Continue to see Figure 3 and Figure 4 , the locking mechanism 3 is arranged at the position corresponding to the spiral groove 1112, and when the guide block 121 slides along the spiral groove 1112, that is, when the second insulating rod 12 rotates relatively, the guide block 121 can be locked by the locking mechanism 3, and then the second insulating rod 12 is locked at the corresponding height. In particular, compared with the arrangement of the telescopic slide groove 1111, the locking mechanism 3 is arranged at the spiral groove 1112, and the vertical gravity borne by the locking mechanism 3 is greatly reduced, which can ensure the stability of the locking. When disassembling the second insulating rod 12, the locking mechanism 3 can be in a non-working state, so that the guide block 121 can slide from the locking mechanism 3 to the positioning groove 1113, and slide out from the top opening to achieve disassembly; when reinstalling, it corresponds to the disassembly method, and will not be repeated in this embodiment. Of course, in other embodiments, the locking mechanism 3 can also be set at the telescopic slide groove 1111, or the telescopic slide groove 1111 can be provided with locking mechanisms 3 at different height positions, and the spiral groove 1112 can also be provided with a locking mechanism 3, so that the locking of the second insulating rod 12 at different extension lengths can be achieved through different locking mechanisms.

[0035] Continue to see Figure 1 , Figure 5 , Figure 7 and Figure 8 The clamping mechanism 2 includes: two clamping plates 21 and a clamping drive assembly 22; wherein the two clamping plates 21 are arranged opposite to each other, and the two clamping plates 21 are arranged at the telescopic end of the telescopic insulating rod body 1 in a relatively rotatable manner (such as Figure 7 The top end of the clamping drive assembly 22 is connected to the two clamping plates 21 to drive the two clamping plates 21 to rotate relative to each other to clamp the workpiece to be clamped.

[0036] Specifically, the two clamping plates 21 are arranged at the telescopic end (such as Figure 1The top end shown in the figure), that is, the two clamping plates 21 can rotate relative to each other synchronously and in opposite directions, Figure 7 The state shown is the loose state of the two clamping plates 21. At this time, the two clamping plates 21 are arranged horizontally. The two clamping plates 21 are respectively connected to the power output end of the clamping drive assembly 22 through a swing arm 23, so that under the drive of the clamping drive assembly 22, the two swing arms 23 can rotate relative to each other synchronously and in opposite directions, thereby driving the two clamping plates 21 to rotate accordingly. For example, when rotating from the loose state to the clamping state, under the drive of the clamping drive assembly 22, the left swing arm 23 rotates counterclockwise, and at the same time, the right swing arm 23 rotates clockwise synchronously. The two rotate in opposite directions and have equal angular velocities, so that the clamping surfaces (such as Figure 7 The top wall shown in the figure) is gradually reduced from the 180° angle, that is, it is close to each other, so as to clamp the two sides of the workpiece to be clamped, and the object can be pulled and other operations can be performed. If there is no workpiece to be clamped, that is, when the clamp is empty, the clamping surfaces of the two clamps 21 can contact in the clamping state. In this embodiment, in order to avoid damage to the workpiece to be clamped when the clamps 21 are clamped, preferably, the clamping surfaces of the two clamps 21 can be provided with rubber pads 24 for elastic buffering when clamping the workpiece to be clamped. Under the action of the two rubber pads 24, the clamps 21 can adapt to objects of different shapes, that is, they can clamp workpieces of different shapes to be clamped, which can not only increase the stability of clamping, but also prevent damage to the workpiece to be clamped under the action of the rubber pads 24.

[0037] Continue to see Figure 5 , Figure 7 and Figure 8 The clamping drive assembly 22 includes: a telescopic support rod 221, a transmission rack 222, two transmission gears 223, and a winch and unwinding wheel 224; wherein the telescopic support rod 221 is arranged inside the telescopic insulating rod body 1, and the telescopic support rod 221 is connected to the telescopic portion of the telescopic insulating rod body 1, i.e., the second insulating rod 12, for synchronously telescoping with the telescopic portion of the telescopic insulating rod body 1, i.e., the second insulating rod 12; the transmission rack 222 is arranged at the supporting end of the telescopic support rod 221 (such as Figure 7 The top of the telescopic support rod 221 is shown in the figure), the transmission rack 222 is partially arranged inside the telescopic support rod 221 and is connected to the telescopic support rod 221 in a slidable manner along the axial direction of the telescopic support rod 221, and meshing teeth are provided on both sides of the transmission rack 222; two transmission gears 223 are respectively arranged on both sides of the transmission rack 222, and the two transmission gears 223 are rotatably arranged above the telescopic insulating rod body 1, and the two transmission gears 223 are respectively meshed with the meshing teeth on both sides of the transmission rack 222; the winch and unwinding wheel 224 is arranged at the connecting end of the telescopic support rod 221 (as shown in the figure), and ... Figure 5The bottom end shown in FIG. 1 is provided with a connecting rope 225 on the winding and unwinding wheel 224, that is, the connecting end of the connecting rope 225 is connected to the winding and unwinding wheel 224, and the tensile end of the connecting rope 225 (such as Figure 7 The top end of the connecting rope 225 passes through the interior of the telescopic support rod 221 and extends to the supporting end of the telescopic support rod 221. The stretched end of the connecting rope 225 is connected to the transmission rack 222, which is used to pull the transmission rack 222 to slide along the axial direction of the telescopic support rod 221, so as to drive the two transmission gears 223 to rotate in opposite directions, thereby driving the two clamping plates 21 to rotate relative to each other, so as to clamp the workpiece to be clamped.

[0038] Specifically, the telescopic support rod 221 can be a telescopic rod member compatible with the telescopic insulating rod body 1. The telescopic support rod 221 is arranged inside the second insulating rod 12 and is coaxially arranged with the second insulating rod 12. The telescopic support rod 221 can be synchronously telescoped and extended with the telescopic insulating rod body 1, that is, when the second insulating rod 12 is telescoped, the supporting end of the telescopic support rod 221, that is, the telescopic end, can be driven to be synchronously telescoped and extended. The telescopic support rod 221 is used to support structures such as the top splint 21, the swing arm 23, and part of the clamping drive assembly 22. The telescopic support rod 221 is provided with a rope threading hole inside so that the connecting rope 225 can pass through the rope threading hole and connect the transmission rack 222 disposed at the supporting end of the telescopic support rod 221 and the winding and unwinding wheel 224 disposed at the connecting end of the telescopic support rod 221, so that the winding and unwinding wheel 224 can be rotated to realize the winding of the connecting rope 225, thereby pulling the transmission rack 222 to perform reciprocating linear motion along the axial direction of the telescopic support rod 221, thereby driving the two transmission gears 223 to rotate synchronously in opposite directions. In this embodiment, the connecting end (such as Figure 7 The right end of the left swing arm 23 shown in the figure) can be coaxially arranged and connected with the transmission gear 223 to rotate synchronously and in the same direction as the transmission gear 223. The support end of the swing arm 23 (such as Figure 7 The left end of the left swing arm 23 shown in the figure is connected to the clamping plate 21, which can drive the clamping plate 21 to rotate and adjust its position along with the transmission gear 223.

[0039] Continue to see Figure 5 The connecting end of the telescopic support rod 221 may be provided with a wire-releasing housing 226, and the winding wire-releasing wheel 224 is rotatably arranged in the wire-releasing housing 226. Specifically, the connecting end of the telescopic support rod 221 is rotatably arranged in the bottom support plate 112, so that the telescopic support rod 221 can rotate with the second insulating rod 12 relative to the first insulating rod 11, so as to avoid problems such as winding of the connecting rope 225.

[0040] In this embodiment, in order to ensure the stability of the clamping of the clamping plate 21, preferably, the winch-paying wheel 224 is connected to a winch locking member (not shown in the figure), which is used to lock the winch-paying wheel 224 on the pay-off shell 226 when the two clamping plates 21 are clamped on both sides of the workpiece to be clamped, so as to prevent the winch-paying wheel 224 from rotating on its own, and thereby prevent the automatic pay-off of the connecting rope.

[0041] Continue to see Figure 5 The winding and releasing wheel 224 is provided with a handle 227, and the handle 227 may be provided with an anti-skid groove, so that the user can rotate the winding and releasing wheel 224 more conveniently and comfortably through the cooperation of the handle 227 and the anti-skid groove, thereby facilitating the winding of the connecting rope 225. Specifically, both ends of the winding and releasing wheel 224 may be provided with a handle 227, and the handle 227 may be a disc structure, which is coaxially arranged with the winding and releasing wheel 224. Among them, the outer wall of the handle 227 is provided with a plurality of anti-skid grooves arranged at intervals along its circumference.

[0042] Continue to see Figure 8 In order to facilitate the reset of the clamping plate 21, that is, to reset it to the loose state, preferably, the transmission rack 222 is placed at the support end (such as Figure 8 A clamping reset spring 228 is provided between the top end of the transmission rack 222 and the telescopic support rod 221, which is used for elastic compression when the transmission rack 222 slides into the telescopic support rod 221, and when the winch and pay-off wheel 224 is in a free state, it pushes the transmission rack 222 to return to the convex position, that is, slide upward, so as to drive the two clamps 21 to rotate relative to each other and release the clamping of the workpiece to be clamped.

[0043] Specifically, the clamping reset spring 228 is sleeved on the outer circumference of the connecting rope 225, and its two ends can be respectively connected to the end of the transmission rack 222 placed in the telescopic support rod 221 and the telescopic support rod 221 to apply a reset force to the transmission rack 222, so that the transmission rack 222 can slide upward under the action of the reset force, thereby driving the two transmission gears 223 to rotate synchronously in opposite directions, and driving the rocker rod 23 and the splint 21 to rotate, so that the splint 21 is reset to a horizontal loosened state.

[0044] Continue to see Figure 8 To ensure the stability of the clamping reset spring 228, preferably, a limit plate 229 is provided at the bottom of the supporting end of the transmission rack 222 placed in the telescopic support rod 221, which can be slidably arranged inside the telescopic support rod 221 to synchronously adjust the position of the transmission rack 222 and compress the clamping reset spring 228.

[0045] Continue to see Figures 2 to 5 , Figure 7 and Figure 8The telescopic structure of the telescopic support rod 221 can refer to the structure of the telescopic insulating rod body 1, and can include: a connecting rod 2211 and a fixing rod 2212; wherein the fixing rod 2212 is sleeved inside the connecting rod 2211, and the fixing rod 2212 is axially extending along the connecting rod 2211 (such as Figure 2 The vertical direction shown in the figure is slidably connected to the connecting rod 2211 for adjusting the telescopic length.

[0046] Specifically, the fixed end of the connecting rod 2211 (such as Figure 2 The bottom end of the connecting rod 2211 shown in the figure can be supported on the bottom support plate 112, and the connecting rod 2211 can be slidably penetrated through the bottom support plate 112, and the fixed end placed on the lower side of the bottom support plate 112 can be fixedly installed with the discharge shell 226. The fixed rod 2212 is slidably arranged inside the connecting rod 2211. In order to avoid the separation between the two, preferably, a limiting groove 22111 is provided on the inner wall of the connecting rod 2211, and a limiting block 22121 matching the limiting groove 22111 is provided on the outer wall of the fixing rod 2212. The limiting block 22121 can be slidably arranged in the limiting groove 22111 to ensure the stability of the sliding of the connecting rod 2211 and the fixing rod 2212. Among them, there are four limiting grooves 22111 and four limiting blocks 22121, and of course, there can be other numbers such as one or more. In this embodiment, no modification is made to them. In this embodiment, the top end of the limiting groove 22111 is an open end, so that the connecting rod 2211 and the fixing rod 2212 can be separated from each other along the axial direction from the top opening, that is, they can be disassembled along with the first insulating rod 11 and the second insulating rod 12, so that the connecting rod 2211 and the first insulating rod 11 are combined into a whole, and the fixing rod 2212 and the second insulating rod 12 are combined into a whole. Figure 6 As shown, the top support plate 122 of the second insulating rod 12 is provided with a mounting hole 1221 and a mounting groove 1222 matching the stopper 22121, and the connecting rod 2211 and the circumferential stopper 22121 can be fixedly installed in the mounting hole 1221 and the mounting groove 1222, so that the second insulating rod 12 can drive the fixed rod 2212 to be synchronously extended and retracted from the connecting rod 2211 while the second insulating rod 12 is extended and retracted. The fixed rod 2212 is provided with a rope threading hole inside, and the connecting rope 225 passes through the inside of the connecting rod 2211 and the rope threading hole.

[0047] In this embodiment, the setting of the limiting groove 22111 and the limiting block 22121 can not only provide limiting guidance, but also enable the connecting rod 2211 and the fixing rod 2212 to rotate simultaneously, thereby avoiding problems such as winding in the device.

[0048] In this embodiment, while the fixed rod 2212 is extending and retracting, the winch and pay-off wheel 224 is synchronously reeled therewith, and after the fixed rod 2212 and the second insulating rod 12 are extended into place and locked by the locking mechanism 3, the connecting rope 225 is reeled in by the winch and pay-off wheel 224 to pull the transmission rack 222 downward, thereby driving the left transmission gear 223 to rotate clockwise, and driving the right transmission gear 223 to rotate counterclockwise synchronously, thereby driving the left swing arm 23 to rotate clockwise with the left transmission gear 223, and the right swing arm 23 to rotate counterclockwise with the right transmission gear 223, so that the two clamps 21 approach each other until the two clamps 21 are clamped on both sides of the workpiece to be clamped, thereby clamping the workpiece to be clamped.

[0049] Continue to see Figure 8 The interior of the fixed rod 2212 is near the telescopic end (such as Figure 8 A guide hole 22122 is provided at the position of the top of the fixed rod 2212, which is matched with the outer contour of the limit plate 229. The limit plate 229 is slidably arranged in the guide hole 22122 along the axial direction of the fixed rod 2212 to guide the sliding of the transmission rack 222 and limit the sliding of the transmission rack 222 at both ends to prevent the transmission rack 222 from completely sliding into the fixed rod 2212 or completely sliding out of the fixed rod 2212 and separating from the fixed rod 2212. The clamping reset spring 228 is arranged on the bottom wall of the guide hole 2212 and fixedly connected to the limit plate 229.

[0050] Continue to see Figure 4 The locking mechanism 3 may include: two locking shells 31 and two locking blocks 32; wherein the two locking shells 31 are installed in parallel on the outer wall of the first insulating rod 11 along the length direction of the guide groove 111; the two locking blocks 32 are respectively arranged in the two locking shells 31, and the two locking blocks 32 are slidably penetrated in the first insulating rod 11 along the radial direction of the first insulating rod 11, when the guide block 121 slides along the guide groove 111, the guide block 121 can push the front locking block 32 in the forward direction of the guide block 121 to retract into the locking shell 31, so that the guide block 121 can slide and lock between the two locking blocks 32.

[0051] Specifically, two through holes arranged at intervals are provided on the first insulating rod 11 corresponding to the spiral groove 1112, and two locking shells 31 are respectively provided at the two through holes, and the spacing of the through holes can be determined according to the guide block 121. The interior of the locking shell 31 is hollow and communicates with the spiral groove 1112 through the through hole, and the locking block 32 corresponds to the locking shell 31 one by one. The corresponding locking block 32 can be slidably penetrated in the locking shell 31 and the through hole, and is used to retract into the locking shell 31 and the through hole when the guide block 121 slides over the locking block 32, and can extend into the spiral groove 1112 when the guide block 121 is limited and locked. When the guide block 121 is locked, the guide block 121 slides from the telescopic slide groove 1111 to the spiral groove 1112, and slides along the spiral groove 1112 toward the locking block 32, and an extrusion force can be applied to the locking block 32 on the front side, that is, the first locking block 32 that is first contacted on the sliding route. The locking block 32 can retract, so that the guide block 121 continues to slide along the spiral groove 1112 through the position of the locking block 32, so as to slide between the two locking blocks 32, and the extrusion of the locking block 32 is released, so that the locking block 32 can be extended into the spiral groove 1112 to limit the guide block 121 from sliding back, and the other locking block 32 is always in an extended state to limit and lock the continued sliding of the guide block 121, so that the guide block 121 is locked between the two locking blocks 32. Of course, when the locking of the guide block 121 is released, the locking block 32 in the forward moving direction of the guide block 121 can be controlled to retract. That is, when the guide block 121 slides toward the telescopic slide groove 1111, the locking block 32 in the forward moving direction of the guide block 121 can be controlled to retract. Figure 4 The upper locking block 32 shown in FIG. 1 is retracted, so that the guide block 121 can pass through the upper locking block 32 to slide into the telescopic sliding groove 1111 to contact and lock, thereby realizing the retraction of the second insulating rod 12. On the contrary, when the guide block 121 slides toward the positioning groove 1113, the control Figure 4 The lower locking block 32 is shown retracted, so that the guide block 121 can pass through the lower locking block 32 to slide into the positioning groove 1113 and can be removed from the positioning groove 1113 .

[0052] Continue to see Figure 4A locking reset member 33 is provided between the locking shell 31 and the locking block 32 therein, and is arranged along the sliding direction of the locking block 32, and is used to push the locking block 32 to reset to extend into the first insulating rod 11, i.e., the spiral groove 1112, after the guide block 121 slides over the locking block 32, so as to limit the guide block 121. Specifically, the locking reset member 33 is a spring structure, which can be elastically compressed when the locking block 32 retracts into the locking shell 31, i.e., when the guide block 121 squeezes the locking block 32 to retract into the locking shell 31, and applies a reset force to the locking block 32, so that after the guide block 121 passes the position where the locking block 32 is located, the locking block 32 is in a free state, so that the locking block 32 extends into the spiral groove 1112 under the action of the reset force of the locking reset member 33, so as to limit the sliding back of the guide block 121.

[0053] Continue to see Figure 4 In order to improve the telescopic stability of the locking block 32, preferably, a locking guide plate 34 is provided inside the locking housing 31, which is slidably arranged in the locking housing 31 along the radial direction of the first insulating rod 11, and the connecting end of the locking block 32 (such as Figure 4 The left end shown in FIG. 1 is connected to the locking guide plate 34, and the other end (as shown in FIG. Figure 4 The right end of the first insulating rod 11 (shown in the figure) is used as a limit end, which can be extended into the first insulating rod 11 or retracted into the locking shell 31, and the locking guide plate 34 is used to guide the sliding of the locking block 32. Specifically, the locking guide plate 34 matches the inner cavity of the locking shell 31, and can slide in the locking shell 31 to guide the sliding of the locking block 32 when the locking block 32 retracts or extends, so that the locking block 32 only moves in parallel, thereby avoiding the problem of deformation and damage caused by the tilting and squeezing of the locking block 32 on the locking reset member 33, and improving the service life of the locking reset member 33. In this embodiment, the locking reset member 33 is sandwiched between the locking guide plate 34 and the locking shell 31 to apply a reset force to the locking guide plate 34 so that the locking guide plate 34 can drive the locking block 32 to reset and extend.

[0054] Continue to see Figure 4 In order to facilitate the unlocking of the locking block 32, preferably, a linkage rod 35 is provided on the locking shell 31, which is slidably penetrated through the locking shell 31, and the linkage rod 35 is placed at the end portion of the locking shell 31 (such as Figure 4 The right end shown in FIG. 1 is connected to the locking block 32, and the linkage rod 35 is disposed at the end outside the locking housing 31 (as shown in FIG. Figure 4A pull ring 36 is provided on the left end of the first insulating rod 11, which is used to drive the locking block 32 to slide along the radial direction of the first insulating rod 11 under the action of external force, so that the locking block 32 is retracted into the locking shell 31, and then the guide block 121 can slide out to the two sides of the two locking blocks 32. Specifically, the end of the linkage rod 35 placed in the locking shell 31 can be connected to the locking guide plate 34, and the locking reset member 33 can be sleeved on the outer periphery of the linkage rod 35. The linkage rod 35 is pulled to slide leftward by the pull ring 36, and then the locking guide plate 34 and the locking block 32 are driven to slide leftward, so that the locking block 32 is retracted into the locking shell 31 or the through hole, preventing the locking block 32 from locking the guide block 121, and unlocking is achieved, and the guide block 121 can also slide smoothly from the locking block 32.

[0055] In this embodiment, in order to allow the locking blocks 32 to retract under the squeezing action of the guide blocks 121 disposed outside the two locking blocks 32, preferably, the locking ends of the two locking blocks 32 (such as Figure 8 The opposite side wall (as shown in the right end) Figure 4 A guide structure 321 is provided on the upper side wall of the upper locking block 32 and the lower side wall of the lower locking block 32, which is used to retract into the locking housing 31 under the pressure of the guide block 121 when the guide block 121 slides from both sides of the two locking blocks 32 to the locking block 32, so that the guide block 121 can slide to and lock between the two locking blocks 32. Specifically, the guide structure 321 is an arc, and the arc is set so that the locking block 32 can squeeze it when it contacts the arc, so that it can easily pass over.

[0056] Continue to see Figure 4 The opposite side walls of the locking ends of the two locking blocks 32 are as follows Figure 4The lower side wall of the upper locking block 32 and the upper side wall of the lower locking block 32 are provided with a locking structure 322, which is used to abut against the side of the guide block 121 when the guide block 121 slides between the two locking blocks 32 to limit the guide block 121. Specifically, the locking structure 322 can be a planar structure, and the locking block 32 can be limited by the provided plane, so that it cannot move, thereby improving the locking efficiency. That is to say, through the cooperation of the telescopic slide groove 1111 and the spiral groove 1112, the second insulating rod 12 can be moved vertically and then rotated, and after the rotation, the guide block 121 can squeeze the guide structure 321 to make the locking block 32 on the front side retract, so that the guide block 121 can slide from the locking block 32 and be placed between the two locking blocks 32, and the retracted locking block 32 is retracted by the locking reset member 33, so that the guide block 121 is locked between the locking structures 322 of the two locking blocks 32, thereby locking the second insulating rod 12; and after the operation is completed, the pulling ring 36 on the front side in the forward direction can be pulled so that the corresponding locking block 32 compresses the locking reset member 33, and the guide block 121 slides over the locking block 32, that is, slides out from between the two locking blocks 32, so that the second insulating rod 12 can be retracted, and can be slid back to the positioning groove 1113 for removal and replacement.

[0057] The use principle of the insulating rod: When in use, the second insulating rod 12 is pulled to make the second insulating rod 12 slide outward along the axial direction of the first insulating rod 11 until it cannot move axially, and then the second insulating rod 12 is rotated. When the second insulating rod 12 rotates, the guide block 121 contacts the guide surface of the locking block 32 on the front side of the forward direction, thereby squeezing it. While squeezing, the locking reset member 33 is squeezed and compressed by the locking block 32. When the second insulating rod 12 passes over, the locking block 32 is ejected by the elastic force of the locking reset member 33. At this time, the guide block 121 is located between the locking structures of the two locking blocks 32, so that the guide block 121 can be limited and locked. At this time, when the first insulating rod 11 and the second insulating rod 12 are in use, the second insulating rod 12 12 will not be retracted, and the restriction on the guide block 121 can be released by pulling the pulling ring 36, so that the second insulating rod 12 can be retracted or the second insulating rod 12 and the first insulating rod 11 can be removed for storage or replacement; wherein, while pulling the second insulating rod 12, the fixing rod 2212 can be driven out from the inside of the connecting rod 2211, so that the height of the clamping mechanism 2 can be adjusted at the same time. When it is needed, the connecting rope 225 is wound up by rotating the winding and unwinding wheel 224. During the winding process, the transmission rack 222 is driven to move downward, and the clamping reset spring 228 is compressed. While moving, the transmission gear 223 and the rocker arm 23 can be driven to rotate, so that the two clamping plates 21 are close to each other, thereby clamping the workpiece to be clamped.

[0058] In summary, the lightweight live working insulating rod provided in the present embodiment is extended and retracted through a telescopic insulating rod body. When the telescopic insulating rod body is extended and retracted to a corresponding length, the telescopic insulating rod body is locked by a locking mechanism, so that the telescopic insulating rod body that is extended and retracted into place can be stably fixed during the operation process, avoiding the risk of accidental retraction. It can not only solve the problem that the existing live working insulating rod cannot adjust the tool height during high-altitude operations, making it difficult to store, but also, by locking the telescopic insulating rod body through the locking mechanism, the safety and stability of the operation are increased, the stability during high-altitude operations is improved, and it is ensured that the operator can focus on the operation, and the potential dangers caused by the instability of the tool are reduced; the clamping mechanism is used to clamp the workpiece to be clamped, so that the workpiece to be clamped can be subjected to live working, which improves the operating efficiency of the operator when performing various tasks, especially by adjusting the clamping force and adapting to the use height of the insulating mechanism, it can better adapt to the clamping requirements of different objects, ensuring efficient and accurate completion of the operation.
