Abstract
The utility model relates to an extracting part for the replaceable head of a tool. The tool is provided with a clamping jaw head, a clamping jaw sleeve and a screw assembly, wherein the clamping jawhead is used to clamp the replaceable head, the clamping jaw sleeve is arranged between the clamping jaw and the replaceable head in a penetrating way, and the screw assembly is combined with the clamping jaw head in a screwing way and is used to collect the clamping jaw head. The clamping jaw sleeve is forced by the clamping jaw head and is tightly fixed on the replaceable head. The extracting part includes a penetrating section and a holding section connected with the penetrating section. The penetrating section is provided with two clamping jaws which are arranged at a certain distance. Each clamping jaws is provided with a retaining edge formed on the external surface. When the clamping jaw sleeve is required to be extracted out, the penetrating section is penetrated through the clamping jaw sleeve to eject the clamping jaws out of the clamping jaw sleeve and the retaining edges are blocked against one end edge of the clamping jaw sleeve. Thereby, the clamping jaw sleeve can be pulled out under force if only the holding section exposed outside the clamping jaw head is held. The utility model has the advantages that the time for the replacement is shortened and the convenience of use is improved.
Description
[technical field]
The utility model relates to a kind of taking-up part, particularly relates to a kind of taking-up part that is used to take out the instrument replacement head of assembly.
[background technology]
Consulting Fig. 1, is example with general pneumatic tool group 1, consists predominantly of a pneumatic tool 11, several replacement heads 12,13, and a jaw cover 14.This pneumatic tool 11 has a jaw head 111 that is subjected to gas pressure and rotates, and reaches a screw piece 112 that screws togather with this jaw head 111.This replacement head 12 has a big bar footpath section 121.This replacement head 13 has a small pole diameter section 131.This jaw cover 14 is used for selectivity and places in this jaw head 111, in order to dwindle the aperture of this jaw head 111.
When this pneumatic tool 11 is selected this replacement head 12 for use, need only be directly the big bar footpath section 121 of this replacement head 12 be placed in this jaw head 111, stablize this jaw head 111 with an instrument (figure does not show) again, reach with another instrument (figure does not show) spiral shell and advance this screw piece 112, just can bring the big bar footpath section 121 of these jaw head 111 fastening these replacement heads 12 together.
When this pneumatic tool 11 is selected this replacement head 13 for use, must earlier this jaw cover 14 be placed in this jaw head 111, in order to dwindle the aperture of this jaw head 111, the small pole diameter section 131 of this replacement head 13 could be placed in this jaw cover 14, whereby, can advance this screw piece 112 by spiral shell equally, change a small pole diameter section 131 of 13 in order to bring fastening this of this jaw head 111 together.
Yet, 14 volumes are less and whole to be hidden in this jaw head 111 because this jaw overlaps, therefore, though can replacing, aforementioned pneumatic tool 11 uses the not replacement head 13 of same-action, must be when replacing, with these screw piece 112 whole this jaw heads 111 that unload, cautious again this jaw cover 14 that plucks out, just can finish the replacement program, not only inconvenient in the use, and quite consume the time.
[utility model content]
The purpose of this utility model is to be to provide a kind of can promote ease of use, and the taking-up part of the instrument replacement head of reduction replacement time.
This instrument have this replacement head of clamping a jaw head, be set in a jaw cover between this jaw head and this replacement head, reach a screw piece that screws togather and bring together this jaw head with this jaw head, this jaw cover is to be forced in this jaw head and fastening this replacement head, taking-up part of the present utility model comprises the section of placing, and a holding section.This section of placing is to be used to run through this jaw cover, and has two folder jaws that pass this jaw head and the spacing of being separated by, and is formed on aforementioned folder jaw one outer surface and fastens the retaining edge that this jaw overlaps an end.This holding section is to link and be used to be emerging in outside this jaw head with this section of placing.
In the time will taking out this jaw cover, need only run through this jaw cover with this section of placing, make aforementioned folder jaw pass this jaw cover, and fasten at this jaw with aforementioned retaining edge and to overlap an ora terminalis, whereby, need only grip and be emerging in the outer grip part of this jaw head, just can the application of force pull out this jaw cover, and can reduce the replacement time, and promote ease of use.
The beneficial effects of the utility model are: intert and the pull action with simple, take out this jaw cover, reach the reduction replacement time, and promote the purpose of ease of use.

[specific embodiment]
Below in conjunction with drawings and Examples the utility model is elaborated:
Consult Fig. 2, a preferred embodiment of the taking-up part 2 of the utility model instrument replacement head comprises a section of placing 21, and a holding section 22.
This section of placing 21 has and is formed on an end and two of the spacing 210 of being separated by folder jaws 211, is formed on retaining edge 212 of aforementioned folder jaw 211 1 outer surfaces, and is formed on two tangent planes 213 of aforementioned folder jaw 212 outer surfaces relatively.Aforementioned folder jaw 211 be by this retaining edge 212 to a terminal edge 214 by the wide gradually narrow tapering that is formed with.Aforementioned tangent plane 213 is to be used to dwindle aforementioned folder jaw 211 formed Zhou Jing.
This holding section 22 is to link with this section of placing 21, and has several protuberances 221 that are formed on an outer surface.Aforementioned protuberance 221 is embossing in this preferred embodiment.
Consult Fig. 3, Fig. 4, taking-up part 2 of the present utility model is used for using with aforementioned pneumatic tool group 1 collocation, whereby, the jaw head 111 of this pneumatic tool 11 can place this jaw cover 14 equally, in order to the reduced bore, and suitable replacement head 13 than small pole diameter, when the replacement head 12 of preparing to replace big bar footpath, and do not need to use this jaw to overlap at 14 o'clock, need only after unscrewing this screw piece 112 and taking out this replacement head 13, be somebody's turn to do the holding section 22 that takes out part 2, this section of placing 21 is placed in this jaw cover 14 with finger grip, make aforementioned folder jaw 211 be subjected to the extruding of this jaw cover 14, dwindle this spacing 210 and close up mutually, and then utilize the tapering of outer surface, and aforementioned tangent plane 213 formed breach, reduce aforementioned folder jaw 211 and overlap 14 resistances, make aforementioned folder jaw 211 smoothly by this jaw cover 14 with this jaw.
Consult Fig. 4, Fig. 5, because aforementioned folder jaw 211 no longer is forced in this jaw cover 14, therefore, after aforementioned folder jaw 211 passed this jaw cover 14, the outside bullet of meeting was opened and is replied this spacing 210, reaches to fasten at this jaw with this retaining edge 212 respectively and overlaps 14 1 ora terminalis 141.Whereby, need only oppositely force in this holding section 22, just can pull out this jaw cover 14.
What deserves to be mentioned is, taking out this jaw overlapped 14 o'clock, need only urge aforementioned folder jaw 211 with finger shrinks these spacings 210 and closes up mutually, just can utilize the tapering of outer surface equally, and aforementioned tangent plane 213 formed breach, reduce aforementioned folder jaw 211 and overlap 14 resistances, make this jaw cover 14 smooth these sections of placing of slippage 2 with this jaw.
According to the above as can be known, the taking-up part of instrument replacement head of the present utility model has following advantage and effect:
The utility model can not need to dismantle under the situation of this screw piece 112, directly intert and the pull action with simple, take out this jaw cover 14, no matter pneumatic or electric tool, directly be converted to the use of small pole diameter by big bar at clamping device, not only can reduce the replacement time, and can promote ease of use, make to the utlity model has practicality.
