[0009] A stainless steel hanging ring is fixed to the side of the rod sleeve for operating the insulated shooting gun. The cross-section of the hook is a U-shaped structure, and weight-reducing grooves are formed on the outer sides corresponding to the first vertical part, the arc part, and the second vertical part. Reinforcing rib plates are provided in the weight-reducing grooves, and the screw rod is located in the weight-reducing groove corresponding to the first vertical part.

[0010] Furthermore, the rod body is formed by docking a sleeve rod and a sub-rod.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-2 As shown: an eagle-beak type insulating support rod for power cables, comprising a rod body 1, a hook 2 is installed at one end of the rod body 1, and an eagle-beak pliers 3 is installed at the other end, the hook 2 has a first vertical portion 21 and a second vertical portion 22, the first vertical portion and the second vertical portion are parallel to each other, the first vertical portion is consistent with the length direction of the rod body, and are arranged in the same straight line; the length of the second vertical portion is smaller than the first vertical portion, and an arc portion 23 is between the first vertical portion 21 and the second vertical portion 22, which is used to form a complete hook structure, and the inside is a hook groove; the second vertical portion 22 corresponds to a support seat 5 with an arc-shaped arch in the hook groove, and the first vertical portion 21 corresponds to a hook groove with an arc-shaped spring piece 6, the spring piece 6 corresponds to the arc top position of the support seat 5, and the support seat 5 is provided with a groove body 51 for accommodating the spring piece 6 at the arc top position; thereby the spring piece and the arc top corresponding to the support seat can be staggered with each other.

[0019] One end of the spring piece 6 is fixed to the side wall of the hook groove, and the other end has a screw sleeve 61. The end of the rod body 1 has a screw rod 25 sleeved on the screw sleeve 61, which is used to rotate and drive the spring piece 6 to compress.

[0020] The insulating support rod of the utility model has a hawkbill pliers and a hook at the ends. When in use, the screw is rotated to release the spring sheet, so that the arc-shaped arch of the spring sheet is reduced, and the arc top corresponding to the spring sheet is separated from the groove body corresponding to the support seat. The spring sheet and the arc top position corresponding to the support seat form a slot for the cable to be inserted. Since the spring sheet has a certain elasticity, it will overcome the spring sheet when inserted into the cable to cause the spring sheet to deform, and the cable is initially fixed after being inserted. After the cable is inserted, in order to prevent the cable from falling off, the screw is rotated to make the screw sleeve move in the opposite direction, thereby compressing the spring sheet, and the arc top corresponding to the spring sheet is inserted into the groove body to close the slot. In this way, even if the spring sheet can be deformed, the cable is not likely to fall off when it is located in the hook, thereby achieving a stable support effect.

[0021] like Figure 2As shown in the figure: The end of the hook 2 corresponding to the first vertical part 21 is a rod sleeve 24. The end of the rod body 1 is limitedly sleeved in the rod sleeve 24 and is rotationally matched. The screw rod 25 is fixed to the end of the rod body 1 and is coaxially arranged. The hook fixes the rod sleeve, and by rotating the rod body, the screw rod rotates synchronously, so as to realize the deformation of the elastic piece. No additional rotating parts are required, and the operator can also operate at a distance from the hook end. When the hook hooks the cable, by rotating the rod body, the hook cannot rotate synchronously due to the limiting effect of the cable. When the rod body rotates, it can drive the elastic piece to realize the effect of the operator driving at a distance and improve safety. The part of the rod body end corresponding to the sleeved rod sleeve has a limiting ring. The free end of the screw rod is also fixed with a limiting ring to prevent the problem of the screw sleeve rotating and detaching at the end position. A stainless steel hanging ring 7 is fixed on the side of the rod sleeve 24 for operating the insulation gun.

[0022] The cross-section of the hook 2 is a U-shaped structure. Weight-reducing grooves are formed on the outer sides corresponding to the first vertical part 21, the arc part 23, and the second vertical part 22. Reinforcing rib plates are arranged in the weight-reducing grooves. The screw rod 25 is located in the weight-reducing groove corresponding to the first vertical part 21.

[0023] As Figure 1 As shown in the figure: The rod body 1 is formed by docking a sleeve rod 11 and a sub-rod 12. The ends of the sleeve rod 11 and the sub-rod 12 are sleeved with each other and are telescopically matched. A fastening sleeve 13 is installed at the corresponding sleeved position of the sleeve rod 11 and the sub-rod 12. The splicing structure of the sleeve rod and the sub-rod enables the rod body to have a length adjustment function, and the length can be adjusted according to needs to match the best support effect. After determining the length of the rod body, the length of the rod body is fixed by rotating the fastening sleeve.

[0024] As Figure 3 As shown in the figure: An angle adjuster 4 is installed at the end of the rod body 1 corresponding to the end of the pliers 3. The angle adjuster 4 includes two side limiting plates 41. A first clamping plate and a second clamping plate are installed in the clamping groove between the two side limiting plates 41. The first clamping plate is fixed to the pliers 3, and the second clamping plate is installed with an adjusting knob 42. The overlapping sides of the first clamping plate and the second clamping plate have limiting teeth. Rotating shafts are fixed in the centers of the first clamping plate and the second clamping plate respectively. The limiting plates have shaft holes for the rotating shafts to pass through, so that the first clamping plate and the second clamping plate can rotate along the axis for adjusting the angle of the pliers to prevent the cable from being twisted. After adjusting the position of the pliers, rotate the second clamping plate to press the first clamping plate, and the corresponding limiting teeth are engaged with each other to lock the position of the pliers.

[0025] These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present invention, so that those skilled in the relevant technical field can well understand and utilize the present invention.
