Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

Example 1

As shown in fig. 1-3, an electrified fastening tool of insulator bolt comprises a sleeve 1, an insulating base 2, an insulating operating rod 3 and an operating handle 4, wherein the sleeve 1 is installed on the insulating base 2, the insulating base 2 is installed on the top end of the insulating operating rod 3, the operating handle 4 is located at the bottom end of the insulating operating rod 3, anti-skid lines are arranged on the operating handle, a rotating ring 5 is arranged in the middle of the insulating operating rod, and the rotating ring 5 is in running fit with the insulating operating rod 3, so that the rotating operation is smoother.

As shown in fig. 2, the sleeve 1 includes a sleeve portion, a stepped circular hole 11 located in the sleeve portion, a first rotating member 12 and a second rotating member 13, an outer hole section of the stepped circular hole 11 is larger in diameter than an inner hole section, the first rotating member 12 and the second rotating member 13 are both of a cylindrical structure, the first rotating member 12 and the second rotating member 13 are rotatably mounted in the outer hole section and are overlapped together, an inner hexagonal hole 14 matched with a bolt is arranged at the center of the first rotating member 12 and the second rotating member 13, and the inner hole section of the stepped circular hole 11 is mainly used for accommodating the bolt portion of the insulator.

A first locking hole 15 is formed in the side portion of the first rotating member 12, a second locking hole 16 is formed in the side portion of the second rotating member 13, two operation holes 17 are formed in the sleeve 1 corresponding to the first locking hole 15 and the second locking hole 16, and a pin 18 is installed in each operation hole 17.

In the locked state of the first rotating member 12 and the second rotating member 13, the inner hexagonal holes in the first rotating member 12 and the second rotating member 13 are aligned.

The working principle is as follows:

when the inner nut needs to be screwed preferentially, the first rotating piece 12 positioned on the outer side is locked through the pin, the pin on the second rotating piece 13 is taken out, the second rotating piece 13 is in a movable state, then the sleeve is sleeved on the double nuts, if the outer peripheral surfaces of the double nuts are in accordance with the specification and are aligned together, the operation is not needed, the first rotating piece 12 is sleeved on the inner nut, the second rotating piece is sleeved on the outer nut, then the rotating ring 5 is held by one hand, the operating handle is rotated by the other hand, at the moment, the first rotating piece 12 is limited by the pin and synchronously rotates along with the sleeve, the inner nut is independently tightened, and the second rotating piece 13 cannot rotate along with the pin due to being in the movable state and only can be static relative to the outer nut.

Generally, the inner nut only needs to be tightened for half turn, can be completely tightened for at most one turn, tries to directly withdraw when needing to withdraw, directly withdraws if withdrawing, continues to tighten the inner bolt if the first rotating member 12 is limited by the outer bolt and cannot withdraw, continuously tries to withdraw in the tightening process until withdrawing is possible, slightly loosens the inner bolt if overtightening is too tight and cannot be tightened any more, enables the inner bolt to correspond to the outer bolt and the outer bolt to correspond to the inner bolt, then withdraws, and does not influence the tightness because the looseness is only less than 60 degrees.

After the screw is withdrawn, the first rotating member 12 controls the outer nut to tighten the screw.

If the inner and outer bolts are synchronous in height, the first rotating member 12 and the second rotating member 13 can be locked, and then the inner and outer bolts can be synchronously screwed to realize synchronous tightening.

Example 2

As shown in fig. 4, the present embodiment is different from embodiment 1 in that: a compression spring 19 is arranged between the pin 18 and the operation hole 17, and the compression spring 19 always drives the pin to compress inwards.

An operable movable limiting block (not shown in the figure) for limiting the inward pressing of the pin 18 is arranged on the outer side of the sleeve 1, such as a common pin mode, a common lock tongue mode and the like.

The use is the same as in embodiment 1, except that the fastening of the pins 18 is more concise and easier to operate.

Example 3

As shown in fig. 5, the outer end of the pin 18 is provided with a limiting arm 21 which forms an angle of 90 degrees with the pin, the limiting arm of the pin is disc-shaped, the operable movable limiting block 20 is a sliding block which is slidably mounted on the outer wall of the sleeve along the longitudinal direction, the front end of the sliding block is an inclined plane, the sliding block is opposite to the limiting arm, the sliding block can slide to the lower part of the limiting arm to jack up the limiting arm, the operable movable limiting block 20 is driven by a spring to slide to the limiting arm, a buckle is arranged on the operable movable limiting block, an operating rope 21 is tied on the buckle, and the operating end of the operating rope 21 is tied at an operating handle.
