Further, described conductor spacer replacing instrument is also provided with shackle.
The beneficial effects of the utility model:
Instrument changed by conductor spacer of the present utility model, operating grip drive sleeve is rotated thus is made leading screw moving axially along installing hole in sleeve, and be provided with elastic spacing one in the bottom of installing hole, the periphery on screw mandrel top is provided with stopper slot, when screw mandrel outwards moves to elastic spacing one position, elastic spacing one springs in stopper slot, the outwards movement of restriction screw mandrel, reach the effect of slip-off preventing, because the direction of stopper slot along the hand of spiral setting of screw mandrel and towards screw mandrel top is deepened gradually, therefore screw mandrel can move return to the inside.
These features of the present utility model and advantage will embodiment below, exposure detailed in accompanying drawing.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model Elastic locating part;
Fig. 3 is the structural representation of stopper slot in the utility model;
Fig. 4 is the connection diagram of the utility model split shed pin drag hook and operating grip.
[embodiment]
The technical scheme of accompanying drawing to the utility model embodiment below in conjunction with the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in execution mode, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection range of the present utility model.
With reference to figure 1, Fig. 2 and Fig. 3, instrument changed by shown a kind of conductor spacer, comprise leading screw 1, the operating grip 3 that sleeve 4 and drive sleeve 4 are rotated, the top of screw mandrel 1 is threaded with sleeve 4, the bottom of screw mandrel 1 is provided with bayonet lock 5, screw mandrel 1 connects the wire clamp of conductor spacer, operating grip 3 rotational sleeve 4, screw mandrel 1 is made to move to realize the installation or removal of conductor spacer, the bottom surface of sleeve 4 is provided with installing hole 43, installing hole 43 is provided with the thread segment 42 of connection wire rod 1, thread segment 42 and screw mandrel 1 are rotationally connected, the movement of screw mandrel 1 along installing hole 43 axis is realized by rotating, the bottom of installing hole 43 is provided with elastic spacing one 6, the periphery on screw mandrel 1 top is provided with stopper slot 11, stopper slot 11 to be arranged and direction towards screw mandrel 1 top is deepened gradually along the hand of spiral of screw mandrel 1, when stopper slot 11 moves to elastic spacing one 6 position, elastic spacing one 6 springs in stopper slot 11, due to the stop of stopper slot 11, screw mandrel 1 can not be rotated further, screw mandrel 1 is prevented to be separated with sleeve 4, screw mandrel 1 is avoided to come off, high-altitude junk is avoided to hit.With reference to figure 3, stopper slot 11 to be arranged and direction towards screw mandrel 1 top is deepened gradually along the hand of spiral of screw mandrel 1, screw mandrel 1 outwards mobile until, elastic spacing one 6 offsets with the sidewall 111 of stopper slot 11, therefore screw mandrel 1 can not continue to move laterally, but screw mandrel 1 can rotate backward, screw mandrel 1 internally return.Utility model works efficiency is high, brings higher economic benefit, and has versatility widely.
Be provided with mounting groove 41 at the inwall of installing hole 43, arrange elastic spacing one 6 in mounting groove 41, elastic spacing one 6 offsets with the periphery of screw mandrel 1.
Wherein elastic spacing one 6 comprises ball 61 and is connected to the stage clip 62 between ball 61 and mounting groove 41, the elastic force of stage clip 62 drives ball 61 to offset with the periphery of screw mandrel 1, be absorbed in stopper slot 11 by ball 61 and realize spacing barrier effect, and when screw mandrel 1 rotates, friction between ball 61 and screw mandrel 1 is little, movable smooth, little to the damage of screw mandrel 1.
Because the distance in the wire clamp upper and lower surface hole in closed state of conductor spacer is 60mm, can 101.5mm be reached under open mode, consider with the distance (23.5mm) of sleeve 4 bottom end face and the operation window (getting 10mm) of necessity, elastic spacing one 6 finally determines that leading screw 1 total length is 135mm.
Operating grip 3 is provided with split pin drag hook 8, replaces by split pin drag hook 8 latch that conductor spacer dismantled by nipper pliers, therefore reduce the aid needing to carry.
With reference to figure 4, the end face of operating grip 3 is provided with link slot 31, and two inwalls that link slot 31 is relative are provided with metal clips 9, and split pin drag hook 8 is clamped between metal clips 9.If split pin drag hook 8 and operating grip 3 linked into an integrated entity, use split pin drag hook 8, need overall conductor spacer of picking up to change instrument; The utility model clamps split pin drag hook 8 by metal clips 9, and split pin drag hook 8 is removably used alone, convenient laborsaving.
With reference to figure 1; sleeve 4 and operating grip 3 are rotationally connected; operating grip 3 can from dotted line position to leading screw 1 sidepiece 90-degree bent, and operating grip 3 is equal with leading screw 1 length, thus is convenient to work high above the ground and carries and protect operating personnel from the unexpected injury of operating grip 3 distal opening pin drag hook 8.
Preferably, be provided with Connection Block 2 at the periphery of sleeve 4, operating grip 3 is rotationally connected Connection Block 2, and operating grip 3 has been threaded tube connector 32, when operating grip 3 and Connection Block 2 are positioned at same straight line, be rotationally connected pipe 32, be socketed the rotation of the spacing operating grip 3 of Connection Block 2 by tube connector 32, thus facilitate the use of instrument, when not needing to use, rotate backward tube connector 32 again, release connection seat 2, then operating grip 3 is folded.
In addition, conductor spacer replacing instrument is also provided with shackle 7, and handled easily personnel carry.
By above-described embodiment, the purpose of this utility model is reached by fully effective.The personage being familiar with this technology should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in embodiment above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
