The specific embodiment

The full clad type ratchet spanner insulation structure-improved that the utility model provides, be provided with a wrench body, described wrench body has a service portion and a shank part, offer a perforation that runs through top, bottom surface on the service portion, in order to a ratchet sleeve order unit to be set, described ratchet sleeve order unit also has one and is made and placed the press section and of the perforation of service portion end face to pass the socket part of the perforation of service portion bottom surface by the insulation material; Be coated with insulation sleeve in the wrench body outside, wherein, insulation sleeve locates to be configured as arc edge teat corresponding to the service portion end face, and arc edge teat end face is concaved with one just can hold the socket of press section, is provided with first through hole of communication bores in the socket; Again, the socket inwall is that arc edge teat apical margin is higher than the press section root edge.

For further understanding and approval being arranged, enumerate following preferred embodiment and conjunction with figs. and elaborate structural feature of the present utility model and effect.

See also Fig. 1 to Fig. 3.Fig. 1 is the stereogram that discloses the utility model first embodiment; Fig. 2 is that the group that discloses first embodiment is established schematic diagram; Fig. 3 is the vertical view that discloses first embodiment.

The utility model ratchet spanner 1 roughly comprises the insulation sleeve 3 that a wrench body 2 and coating are formed in wrench body 2 outsides.

Described wrench body 2 has a service portion 20 and and extends the shank part 21 that is shaped by service portion 20.Offer a perforation 200 that runs through top, bottom surface on the described service portion 20, in order to a ratchet sleeve order unit 22 to be set, described ratchet sleeve order unit 22 has a press section 23 and a socket part 24.Described press section 23 is to be made by the insulation material, and 23 bottom sides, press section are provided with an axostylus axostyle 230 that extends downwards, and 230 end of axostylus axostyle section is provided with a pearl groove 231, in the outer rim place of distance axostylus axostyle 230 1 preset distances, also is concaved with an outer annular recess 232; Press section 23 is by the elastic parts (not shown) and is placed through the perforation 200 of service portion 20 end faces with axostylus axostyle 230.24 of described socket parts are the perforation 200 that passes service portion 20 bottom surfaces, socket part 24 is provided with a hole of bead 240, in the hole of bead 240 and be equipped with the positioning ball 241 of a circle footpath greater than the hole of bead 240, can by push press section 23 with control positioning ball 241 in pearl groove 231 and the hole of bead 240 move, and then control socket part 24 and the object (not shown) desiring to pull between agree with fast or break away from.Also offer one on the described service portion 20 and can one regulate the perforate 201 of the adjusting portion 25 of ratchet sleeve order unit 22 rotation directions in order to be pivoted.

Described insulation sleeve 3 coatings are formed in wrench body 2 outsides, wherein, insulation sleeve 3 is corresponding to service portion 20 places, be to extend to end face by periphery to be configured as arc edge teat 30, arc edge teat 30 end faces are concaved with one just can hold the socket 31 of press section 23, in the socket 31 and offer first through hole 32 that is communicated with the perforation 200 of wrench body 2.When socket 31 is inserted via first through hole 32 in press section 23, can be higher than the inwall (arc edge teat 30) of press section 23 root edges by apical margin, in order to cover the gap of socket 31.

Again, arc edge teat 30 faces in wrench body 2 shank parts 21 places, the recess 34 that is shaped, and described recess 34 also utilizes arc edge teat 30 to form slightly V-shaped stopper section 35, recess 34 faces in the stopper section 35 place, tip, then offers second through hole 33 that is communicated with the perforate 201 of wrench body 2; When adjusting portion 25 is inserted perforate 201 via second through hole 33, can control the rotation direction of ratchet sleeve order unit 22 according to this by the rotation angle of stopper section 35 restriction adjusting portions 25.

Aforementioned is in each member and relativeness thereof of disclosing the preferred embodiment that the utility model provides, and handling characteristics of the present utility model is described below:

See also Fig. 4, and cooperate Fig. 1 to shown in Figure 3.When the utility model carries out Insulation test, utilize an insulation body (not shown) to be nested with on the socket part 24 of the ratchet sleeve order unit 22 of coating insulation sleeve 3 not earlier, afterwards ratchet spanner 1 is inserted one and be full of in the testing arrangement of conduction steel ball 4.Because socket 31 inner edges and the press section 23 periphery sizableness of the insulation sleeve 3 of wrench body 2 outsides, and arc edge teat 30 apical margins are higher than press section 23 root edges, therefore, even press section 23 is when upspringing state, still conduction steel ball 4 can be blocked in apart from outside ratchet sleeve order unit 22 zone far away by arc edge teat 30, conduction steel ball 4 can't be contacted with axostylus axostyle 230 and the ratchet sleeve order unit 22 of position in perforation 200, also can avoid both to form the situation of conduction because of hypotelorism, so can authenticate by test, and then guarantee that the operator does not have the danger of conduction in use.

See also Fig. 5 and Fig. 6 again.Fig. 5 is the stereogram that discloses the utility model second embodiment; Fig. 6 is the schematic diagram that discloses the second embodiment test mode.

In second embodiment, for further reaching the effect of isolated electric arc, described insulation sleeve 3 also convexes with the interior ring protuberance 36 of an insulation in first through hole, 32 outsides of arc edge teat 30.

When socket 31 is inserted via first through hole 32 in press section 23, except that the inwall (arc edge teat 30) that is higher than press section 23 root edges by apical margin covers socket 31 gaps, press section 23 is encircled on the protuberance 36 in can being sheathed on outer annular recess 232 simultaneously, in view of the above, can prolong conduction steel ball 4 and position at the axostylus axostyle 230 of perforation in 200 and the conductive path of first 22 of ratchet sleeve order, and then eliminate may produce the phenomenon of electric arc, in order to do guaranteeing that the operator does not have the danger of conduction in use.

More than explanation, it only is better embodiment of the present utility model, be intended to clear and definite feature of the present utility model, be not in order to limit the scope of the utility model embodiment, the equalization that those skilled in the art do according to the utility model changes, and change well known to those skilled in the art, must belong to the scope that the utility model is contained.
