The embodiment of the electric insulating operation rod of the utility model, as shown in fig. 1 to 8, comprises a main rod body 1 with an operation head 11 at the upper end and a hand-held part 13 at the lower end, a cavity 6 extending along the up-and-down direction is arranged in the hand-held part 13, a through hole 14 for communicating the outside of the main rod body 1 is arranged on the inner wall of the cavity 6, an anti-skid block 2 is movably inserted in the through hole 14, the cavity 6 is provided with a top block 4 which is matched with the antiskid block 2 to push outwards and a driving piece which is used for driving the top block 4 to slide up and down in a sliding way, one end of the driving piece is connected with the top block 4, the other end of the driving piece penetrates out of the cavity 6 to the outside of the main rod body 1 and then is positioned outside the main rod body 1, the driving piece drives the ejecting block 4 to slide and eject the anti-skid block 2 to enable the anti-skid block to protrude outwards out of the outer wall of the handheld part 13, so that the grasping stability of the handheld part 13 is improved.

In the present embodiment, the cavity 6 is cylindrical, and in other embodiments, it may be square-cylindrical.

In this embodiment, the end surfaces of the anti-skid block 2 and the top block 4 which are pushed and matched outwards are planes extending along the up-down direction, the top block 4 is a conical structure with a large upper end and a small lower end, the top block 4 moves downwards so as to push the anti-skid block 2 to move outwards, specifically, the inclined surface 41 in the conical structure of the top block 4 pushes the anti-skid block 2, and in addition, in order to support the anti-skid block 2 when not protruding out of the through hole 14, the lower end of the top block 4 is provided with a supporting part 42 for supporting the anti-skid block 2. The end surface of one end of the antiskid block 2 far away from the top block 4 is provided with a groove 21 convenient for fingers to grasp.

In other embodiments, the end surface of the anti-skid block 2 and the top block 4 which are pushed and matched outwards is of a slope surface 41 structure.

In this embodiment, the top block 4 is provided at an upper end thereof with an elastic member, i.e., a spring 3, which is elastically connected to an upper end of the cavity 6, and the spring 3 stores force after the top block 4 is driven, thereby providing restoring force to the top block 4 after the driving of the top block 4 is released.

In other embodiments, an elastic member may be further disposed at the lower end of the top block 4, and the elastic member may also be a rubber band or the like.

In this embodiment, the lower end of the cavity 6 is sealed by an end cover 15, and a mounting cover 12 for facilitating mounting and maintenance of the spring 3 is disposed at a position of the handheld portion 13 corresponding to the spring 3.

In this embodiment, the driving member is a traction rope 5 having an upper end connected to the lower end of the top block 4 and a lower end extending out from the end cap 15 of the lower end of the main rod body 1 and located below the main rod body 1, and a pull ring 51 is disposed at an end of the traction rope 5 located below the main rod body 1.

In order to lock the top block 4 after the pulling of the pulling rope 5 on the top block 4, the lower end of the main rod body 1 is provided with a rope winding column 52 for winding the pulling rope 5 to lock the position of the top block 4, and the lower end of the rope winding column 52 is provided with a hook for hooking the pull ring 51.

In other embodiments, the driving member may also be a pull rod, or a handle disposed on the top block 4, and one end of the handle penetrates out of the cavity 6 and the main rod 1 and is located outside the main rod 1, in which case the anti-slip block 2 may be directly gripped to compress the anti-slip block 2 and the top block 4, so as to prevent the top block 4 from returning to the original position, or an elastic member may not be disposed.

In other embodiments, the through hole 14 and the cleat 2 may be provided with a stopping mechanism to prevent the cleat 2 from separating from the through hole 14, such as attaching a stopping edge.

When in specific use, the hauling rope 5 is pulled to lead the top block 4 to slide downwards, the inclined surface 41 of the top block 4 pushes the antiskid block 2 to move outwards until the top block 4 can not push the antiskid block 2 any more, the pulling rope 5 is then wound around the rope winding stud 52 and the pull ring 51 is hung on the hook on the rope winding stud 52, at which time, the top block 4 is fixed, the antiskid block 2 protrudes out of the outer wall of the main rod body 1 and is supported by the top block 4 at the upper part of the inclined surface 41, therefore, the regular cambered surface structure of the surface of the handheld part 13 is broken, the surface of the handheld part 13 is of an uneven anti-skid structure, the original anti-skid lines or anti-skid glue layers on the surface of the auxiliary handheld part 13 can be used, the convex anti-skid blocks 2 can greatly enhance the holding stability of an operator to the handheld part 13, the anti-skid capacity is higher, the change of load and moment caused by the increase of the main rod body 1 can be adapted, and the purpose that the handheld part 13 can be adapted and adjusted to enhance the anti-skid capacity after the length of the main rod body 1 is increased is achieved; after the use is finished, the traction rope 5 is wound down from the rope winding column 52, the top block 4 returns under the pulling of the spring 3, the top block 4 does not push the antiskid block 2 any more, and therefore the antiskid block 2 can be retracted into the through hole 14. The utility model discloses a handheld portion 13 can adapt to the adjustment in order to strengthen anti-skidding ability after 1 length of mobile jib body increases, still has compact structure, and the appearance changes little advantage.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
