Abstract

The utility model relates to an improved structure of adapter coupling base of hand tool, which is formed by locking the sliding bar joint on the adapter coupling base, wherein the adapter coupling base comprises a main body, a top stop lever, an offsetting spring and a conical spring. A groove body is formed in the main body; the lower end of the main body extends out and is provided with a ball groove, a steel ball body and a cylinder for socket joint of the sleeve barrel; the top stop lever is T-shaped and provided with a two-segment type stage surface groove where the steel ball body can move; the offsetting spring contains the top stop lever, and is against the lower fringe of the head end of the stop lever; the conical spring is contained in the head end of the stop lever; the groove body surface of the adapter coupling base is provided with a concave surface for locating of the steel ball on the sliding bar joint. After the above components are assembled, if the sliding bar joint is pressed, the steel ball body on the cylinder of the main body is retracted into the stage surface groove of the stop lever, thereby achieving convenient separation from the work pieces such as the sleeve barrel.

The specific embodiment

At first see also shown in Figure 1, the adapter structural improvement of the utility model hand-held tool, it is fastened on the adapter 20 by slide bar joint 10 and combines, primary structure of the present utility model is:

Adapter 20 comprises body 21, top fixed pawl 22, back-moving spring 23 and taper spring 24, wherein body 21 inside form cell bodies 211, be provided with concave face 212 and groove 213 in cell body 211, this concave face 212 is for 11 location of the steel ball on slide bar joints 10, and extends cylinder 216 that the socket that is provided with pearl groove 214 and steel ball body 215 uses in body 21 lower ends for the engaging that socket-connects of elements such as sleeves.

Above-mentioned concave face 212 is principal character of the present utility model: 211 of the cell bodies of this adapter 20 are provided with the concave face 212 for the location of the steel ball on the slide bar joint 10.

Top fixed pawl 22 is the T shape, which is provided with two-period form class face 221, and at this movable telescopic, back-moving spring 23 contains top fixed pawl 22 for steel ball body 215, and is butted on head end 222 lower edges of top fixed pawl 22, so as to produce the elastic force effect when pushing.

Taper spring 24 contains the head end 222 of top fixed pawls 22, and this top fixed pawl is limited in the set groove 213 of cell body 211, plays the spacing effect of compression.

When assembling is implemented, see also Fig. 2 to shown in Figure 4, and cooperate aforementioned shown in Figure 1, at first top fixed pawl 22 holds to go in the back-moving spring 23, and prop up head end 222 lower edges of this top fixed pawl 22, be located in the cylinder 216 of

body

21,24 covers of taper spring are restrainted on the head end 222 of top fixed pawl 22, and snap in location in the groove 213 of body 21, this slide bar joint 10 can be inserted in the cell body 211 of body 21, and borrow its set steel ball 11 to be positioned concave face 212 in this cell body 211, so far promptly form whole movement structure.

And operate when implementing, adapter 20 of the present utility model is when with after slide bar joint 10 engages, but 216 general ferrule element of clamping of the cylinder of adapter 20 are controlled effect, and when needs substitute ferrule element, then can press down this slide bar joint 10 makes it push top fixed pawl 22, make class's face groove 221 past the moving down on this top fixed pawl 22, the pearl groove 214 of this cylinder 216 promptly appears this moment, and make in the steel ball body 215 retraction class face grooves 221 in this pearl groove 214, as shown in Figure 4, so, the ferrule element of phase clamping originally can hightail, and makes the user substitute or does not re-use.

Taper spring 24 of the present utility model, except head end 222 restraints of cover bundle top fixed pawl 22, it is positioned on the groove 213 of adapter body 21, its another function is, when compressing top fixed pawl 22 when down moving, can limit it and keep somewhere, be unlikely ejection or displacement and move smooth and easy in adapter 20.

Concave face 212 of the present utility model also can replace implementing with groove structure or slotted hole shape, and effect is also identical, and it makes the utility model practical more on the implementation.

And what deserves to be mentioned is, of the present utility modelly make and process all convenient, not only can produce in a large number fast, more can save lot of materials and manufacturing cost, can improve productivity effect and economic efficacy for industry, its operation is simple and easy fast, is nothing but an excellent product for the user.Generally speaking, the utility model is not only broken through the use structure of adapter in the past, has more practicality and convenience.
