Also referring to Fig. 1 to Fig. 4, now a kind of pull-out fuse spanner provided by the utility model is said It is bright.A kind of pull-out fuse spanner, including handle 1 and leg 2, leg 2 is two sections of straight-bars being arranged in parallel, handle 1 The rectangle guide groove 3 with 2 matching ends of leg is axially inside opened up, rectangle guide groove 3 can be two and match somebody with somebody respectively with two legs 2 The guide groove of conjunction or one section of straight slot that can accommodate two legs 2 simultaneously, 3 length direction both ends of guide groove have with 1 both ends of handle Certain spacing, not through handle 1, the depth that such leg 2 is plugged in guide groove 3 reaches maximum and has 3 depth direction of guide groove It is unlikely to, through handle 1, handle 1 to be made to play good fixation to leg 2；2 both ends of leg are clamping part 21 and card respectively Socket part 22, wherein clamping part 21 and the clamp flange opening of pull-out fuse coordinate, and clamping portion 22 is plugged in guide groove 3, is blocked Socket part 22 can be slided along 3 length direction of guide groove, adjust two legs, 2 spacing, compared with various sizes of clamp flange, 2 spacing of leg is adjusted to suitable distance and is fastened.

A kind of pull-out fuse spanner provided by the utility model, compared with prior art, can be in narrow and small sky The ring flange of interior fastening pull-out fuse, is easy to use quick, and can be directed to various sizes of plug-in type and fuse Device ring flange is fastened.

Preferably, opening up several limit holes 4 on 3 side wall of guide groove side by side, limit hole 4 is smaller than 2 clamping portion of leg 22 width, there is that limit hole 4 is corresponding with clamping portion 22 always when clamping portion 22 being made to be slided in guide groove, 4 depth direction of limit hole Axially vertical with handle 1, limit hole 4 runs through the side wall of guide groove 3, with 2 clamping portion of leg, 22 corresponding two limit holes 4 Middle installation spacer pin 5, spacer pin 5 are contacted through limit hole 4 with clamping portion 22, and the effect of spacer pin 5 is fixing leg 2, is made whole A pull-out fuse spanner stabilized structure, is unlikely to twist in stress.

Preferably, the clamping part 21 of leg 2 be arranged to the matched shape of pull-out fuse clamp flange opening, As shown in figure 4, the opening of pull-out fuse clamp flange is generally corner root face shape, clamping part 21 sets quadrangularly therewith Cooperation, if pull-out fuse clamp flange opening is hexagonal root face shape, it is matched that clamping part 21 is arranged to hexagon.

Preferably, the clamping portion 22 of leg 2 be arranged to it is flat, guide groove 3 be rectangular channel, the width of clamping portion 22 is with leading When slot 3 is of same size, flat clamping portion 22 can be securely plugged in rectangle guide groove 3, along with the fixation of spacer pin Effect, the connection of leg 2 and handle 1 are more firm.

Preferably, 4 inner surface of limit hole, which adds, is tapping into internal thread, 5 outer surface of spacer pin, which adds, to be tapping into and 4 internal thread of limit hole Matched external screw thread, the form that spacer pin 5 is connected through a screw thread with limit hole 4, makes clamping portion 22 of the spacer pin 5 to leg 2 It is not easy to loosen after being fixed, while spacer pin 5 is moved in limit hole 4 in a manner of precession, is operated more convenient.

Preferably, with reference to Fig. 5,1 both ends of handle can add extension rod 6, and extension rod 6 is slightly larger than handle for one section of size The casing of 1 outer diameter, the fastening become rusty when the larger fastening force of pull-out fuse clamp flange needs or in loosening During flange, the extension rod 6 on 1 one or both ends of handle set holds extension rod 6 and exerts a force, and force torque increase can be played laborsaving Effect.

Preferably, the clamping portion 22 of leg 2, clamping part 21 and intermediate straight-bar are integrally formed, entire leg 2 is enhanced Intensity.

Further, also referring to Fig. 1 to Fig. 5, fastened as a kind of pull-out fuse provided by the utility model A kind of specific embodiment of spanner, because of space constraints, dedicated configuration spanner can not in use, by the utility model one Two legs 2 of kind pull-out fuse spanner are inserted into the guide groove 3 of handle 1, and clamp flanges are measured with two legs 2 The spacing of mouth is leaned in both sides, and for working space is avoided to have particular/special requirement, the off size of leg 2 fits, made when making leg more than 2 A size is different, and several various sizes of legs 2 are only straight-bar length difference, clamping portion 22 and clamping part 21 and full size Leg 2 is identical, and various sizes of leg 2 may be selected in case of need；Equally, according to clamp flange opening shape Difference prepares the leg 2 of several opening shapes more.After choosing suitable leg 2, position of the fine tuning clamping portion 22 in guide groove It puts, when the clamping part 21 of two legs 2 overlaps with clamp flange both-side opening that i.e. clamping part 21 clamps clamp flange completely, Spacer pin 5 is pierced into the limit hole 4 overlapped with 22 position of clamping portion, rotary stopper pin 5 is passed through the side wall of handle 1 and supports Firmly clamping portion 22, the clamping portions 22 of two legs 2 with spacer pin clamping, hold the more clamp flanges of handle rotational fastener spanner into Row fastening loosens, when run into need coupling mechanism force larger or because get rusty situation about can not loosen when, in one end of handle 1 or Both ends set connects extension rod 6, holds extension rod 6 and is fastened or loosened operation.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
