This common operating rod is composed of three parts: a working head, an insulating rod and a handle. The working head is welded into a transverse T-shaped structure, an L-shaped structure, a U-shaped structure or an L-shaped and U-shaped structure by straight steel bars and transverse steel bars. When removing or installing the fuse tube of the drop-type fuse tool, this kind of operation rod can only pick up the fuse tube of the drop-type fuse tool but not clamp the fuse tube, so the fuse tube often falls , It is easy to cause equipment damage, personal injury and other safety hazards

Embodiment Construction
[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:
[0020] see figure 1 with figure 2 , the operating rod of the drop-type fuse tool of the present invention includes an operating rod body 1, a fixed joint 2, a right-angled gram head 4 and a melting tube clamp 5, wherein:
[0021] The operating rod body 1 is made of glass fiber tube; the operating rod body 1 can be connected with multiple insulating rods according to the site conditions, so a connector 10 is installed at the lower end of the operating rod body;
[0022] The fixed joint 2 includes a circular plate with a threaded hole in the center of the surface and a screw rod 3 with a handle screwed in the threaded hole; the surface of the circular plate is provided with a ratchet groove; the fixed joint 2 is fixed on the center of the operating ...

The invention discloses an operation bar of a drop-out fuse. The operation bar comprises an operation bar body, a fixed connector, a right-angle link head and a fusion tube hoop. The fixed connector is fixed at the upper end of the operation bar body and comprises a circular board and a screw, wherein the circular board is provided with a thread hole, and the screw is connected in the thread hole in a screwed mode and is provided with a handle. The right-angled link head comprises a connector circular board fitted with the fixed connector, a straight bar connected at the upper end of the connector circular board, and a transverse bar which is connected in the middle of the straight bar. An opening groove of which the width is fit with the diameter of the screw is formed in the connector circular board in the radial direction. After the opening groove of the connector circular board is clamped on the screw between the handle and the fixed connector, the right-angled link head is fixed on the fixed connector through a tightly-screwing screw. The fusion tube hoop comprises a connecting sleeve, a U-shaped chuck connected on one side of the connecting sleeve, and locking mechanisms which are arranged on the inner sides of two side arms of the U-shaped chuck. The connecting sleeve of the fusion tube hoop is installed on the operation bar body. By means of the operation bar, the phenomenon that a fusion tube drops out when the fuse is switched on can be effectively prevented.
Description
technical field [0001] The invention relates to an operating rod of a drop-type fuse tool. Background technique [0002] The operating stick is an insulated tool used to operate live equipment in a short time, such as connecting or disconnecting high-voltage isolating switches, drop-out fuses, installing and disassembling portable grounding wires, and measuring and testing. After the current drop-out fuse is installed, when the fuse tube needs to be removed or installed, the operator usually uses an operating stick to do so. This common operating rod is composed of three parts: a working head, an insulating rod and a handle. The working head is welded into a transverse T-shaped structure, an L-shaped structure, a U-shaped structure or an L-shaped and U-shaped structure by straight steel bars and transverse steel bars. When removing or installing the fuse tube of the drop-type fuse tool, this kind of operation rod can only pick up the fuse tube of the drop-type fuse tool but...
