The combination of the upper block and the cross block is equivalent to a lever, and the edge of the angle steel cross arm is equivalent to a supporting point. Thus, when the upper bolt is tightened, the upper block can bear a supporting force of the cross plate while clamping the angle cross arm cross plate. The inner end of the upper block, namely one end of the upper block close to the block hinge shaft, is gradually pried up by the transverse plate along with the gradual tightening of the upper bolt, namely swings downwards by taking the edge of the transverse plate as the center. When the inner end of the upper block swings downwards, the lower block is driven to move downwards through the block hinge shaft, and the wedge-shaped block is also driven to transversely extrude the angle steel cross arm, so that the effect of assisting the lower block to position the angle steel cross arm downwards is achieved.

Like this, when fastening the warning sign to the tablet frame, can penetrate the clamp hole on the clamp ring earlier with fastening bolt, then penetrate in warning sign and the clamp hole on the tablet frame in proper order again, screw up the nut at last and can realize warning sign and tablet frame's firm being connected, the operation is very simple.
A brace rod 17 is supported and connected between the middle part of the upper plate 3 and the upper end of the card frame. After setting up the vaulting pole, the riser, the upper plate just roughly encloses into a triangle-shaped frame construction, can know according to triangle-shaped stability principle, this kind of triangle-shaped frame construction has extremely strong stability, can guarantee that the upper plate can not the relative tablet frame activity in this triangle-shaped frame construction place plane, has strengthened the perpendicular connected relation of riser with the upper plate greatly, has just also guaranteed the structural stability of tablet frame on electric power angle steel tower, even meet strong wind and blow and scrape also can not warp.
The main block comprises an upper block 02 and a lower block 03 which are hinged together through a block hinge shaft 01 which is arranged in parallel with the length direction of the angle iron cross arm, the upper block is fixedly connected with the cross block, and the blind hole and the sliding groove are arranged on the lower block. After the main block is set to be of a two-body structure of the upper block and the lower block, when the cross block and the upper plate are locked by the upper bolt, the upper block can move upwards along with the locking force of the upper bolt, so that the transverse plate of the angle steel cross arm can be effectively clamped between the upper plate and the cross block, and the angle steel cross arm is equivalently fixed at the upper part more reliably. Similarly, when the lower bolt is tightened, the lower bolt drives the compression block to approach the lower plate, and at this time, although the moving directions of the lower block and the upper block are opposite, the lower block does not obstruct the upper block to move upwards and the upper block does not obstruct the lower block to move downwards because the lower block and the upper block are of a two-body structure. Therefore, when the lower stud is screwed, the pressing block can drive the wedge block to more smoothly apply transverse extrusion force to the longitudinal plate of the angle cross arm, and the angle cross arm is equivalently fixed at the lower part more reliably. In this patent, the one end that goes up the piece and be close to the angle steel cross arm is articulated together through a piece hinge between the piece upper portion down, goes up the piece like this and just can mutually swing the cooperation with lower piece. The axial direction of the block hinge shaft is parallel to the length direction of the angle steel cross arm, namely the axial lead of the block hinge shaft is parallel to the longitudinal track line of the angle steel cross arm. When the upper bolt is screwed down, the middle part of the top surface of the upper block is in press support fit with the edge of the angle iron cross arm, so that a lever structure is formed by the combination of the upper block and the cross block and the edge of the angle iron cross arm cross plate. The combination of the upper block and the cross block is equivalent to a lever, and the edge of the angle steel cross arm is equivalent to a supporting point. Thus, when the upper bolt is tightened, the upper block can bear a supporting force of the cross plate while clamping the angle cross arm cross plate. The inner end of the upper block, namely one end of the upper block close to the block hinge shaft, is gradually pried up by the transverse plate along with the gradual tightening of the upper bolt, namely swings downwards by taking the edge of the transverse plate as the center. When the inner end of the upper block swings downwards, the lower block is driven to move downwards through the block hinge shaft, and the wedge-shaped block is also driven to transversely extrude the angle steel cross arm, so that the effect of assisting the lower block to position the angle steel cross arm downwards is achieved.
