[0033] Preferably, the second connecting component 204 includes a hanging plate 204a arranged on the side wall of the rear hanging rod 203c, the side wall of the hanging plate 204a is provided with a first adjustment groove 204b, and the side wall of the rear hanging rod 203c is provided with a second adjustment groove 204c; the fixing component 206 includes a threaded rod 206a arranged in the first adjustment groove 204b and the second adjustment groove 204c, the outer surface of the threaded rod 206a is threadedly connected with a nut 206b, the outer surface of the threaded rod 206a is slidably connected with an arc seat 206c, and the side wall of the arc seat 206c is provided with an arc through groove 206d.

[0034] It should be noted that the threaded rod 206a is located in the arc-shaped through groove 206d, so that the arc plate can adjust the position of the arc block up and down or left and right according to actual conditions.

[0035] When in use, place the hanging plate 204a on the cross arm angle steel 205, so that the hanging rod and the rear hanging rod 203c are in contact with the cross arm angle steel 205, and then move the threaded rod 206a on the upper side to the left and right in the first adjustment slot 204b to a suitable position, and then rotate the nut 206b to push the curved plate to move upward so that the curved plate contacts the cross arm angle steel 205, thereby fixing the hanging plate 204a to the cross arm angle steel 205, and move the threaded rod 206a on the lower side up and down in the second adjustment slot 204c to a suitable position, and rotate the nut 206b to push the curved plate to move left so that the curved plate contacts the cross arm angle steel 205, thereby fixing the hanging plate 204a to the cross arm angle steel 205, and move the threaded rod 206a on the lower side up and down in the second adjustment slot 204c to a suitable position, and then rotate the nut 206b to push the curved plate to move left so that the curved plate contacts the cross arm angle steel 205, thereby fixing the rear hanging rod 203c to the cross arm angle steel 205 05, then move the telescopic rod 201b so that the telescopic rod 201b extends out from the fixed rod 201a, and make the safety buckle 102 buckle on the wire.

[0037] Example 2

[0038] Reference Figure 2 to Figure 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a transmission line cross-insulator bridge device, which includes a reinforcement component 207 including a reinforcement seat 207a arranged on the outer surface of the threaded rod 206a, the side wall of the reinforcement seat 207a is fixedly connected to a rubber pad 207b, a rotating rod 207c on the outer surface of the threaded rod 206a, the outer surface of the rotating rod 207c is fixedly connected to an eccentric cam 207d, and the side wall of the eccentric cam 207d is opened with a rotation groove 207e.

[0039] Specifically, the reinforcement seat 207a and the rubber pad 207b are both arranged in an annular shape, so that the reinforcement seat 207a and the rubber pad 207b are movably connected to the threaded rod 206a, and the rotating rod 207c passes through the threaded rod 206a and is rotatably connected to the threaded rod 206a.

[0041] Specifically, the two limiting grooves 208d are symmetrically arranged, the limiting block is plug-connected with the limiting groove 208d to play a limiting role, and the limiting block 208c is slidably connected with the second groove 208a.

[0042] When in use, in conjunction with Example 1, after the arc block contacts the cross arm angle steel 205 to achieve the fixation of the rear hanging rod 203c and the cross arm angle steel 205 and the fixation of the hanging plate 204a and the cross arm angle steel 205, the eccentric cam 207d is moved, so that the eccentric cam 207d is deflected under the action of the rotating rod 207c, and the eccentric cam 207d squeezes the rubber pad 207b and the reinforcement seat 207a, so that the corresponding two reinforcement seats 207a are tightly attached to the rear hanging rod 203c and the hanging plate 204a, respectively, to achieve secondary reinforcement, so that the device and the cross arm angle steel 205 are fixed more firmly, and the safety is improved;

[0043] In conjunction with Example 1, when the telescopic rod 201b is to be extended from the fixed rod 201a, it is necessary to press the limiting block 208c first so that the limiting block 208c is located in the second groove 208a, and then the telescopic rod 201b is moved so that the telescopic rod 201b moves outward from the fixed rod 201a and extends out. When the limiting block 208c corresponds to the limiting groove 208d, the limiting block 208c is quickly inserted into the limiting groove 208d under the action of the spring 208b, so that the telescopic rod 201b is fixed to the fixed rod 201a, effectively preventing the telescopic rod 201b from retracting into the fixed rod 201a during use, preventing the maintenance personnel who step on the telescopic rod 201b from being affected, and further improving safety.

[0049] When in use, in order for maintenance personnel to hang the safety buckle 102 on the wire at the crossarm position, the maintenance personnel only needs to pull the pull ring 202c to pull the pull rope 202a, and open the lock of the safety buckle 102 under the action of the tension, and then hang the safety buckle 102 on the wire, loosen the pull ring 202c, so that the lock of the safety buckle 102 is reset (the lock of the safety buckle 102 is connected to the safety buckle 102 by a torsion spring, and it will automatically reset when the tension is lost. This is the existing technology and will not be elaborated here), thereby achieving the purpose of the maintenance personnel hanging the safety buckle 102 on the wire at the crossarm position.
