The specific embodiment

Technology contents of the present utility model, characteristics and effect will be elaborated in following conjunction with figs..

Fig. 1,2,3 is the preferred embodiment of hand-held tool connecting rod of the present utility model, and this connecting rod comprises: a body of rod 10, a pilot pin 20, a connection piece 30, a card pearl 40, a spring 50, a sliding sleeve 60, first clasp 70 and second clasp 80.

This body of rod 10 has first end 11, is non-circular the second end 12 along an axial X in contrast to first end 11 and cross section, and the outer shroud caulking groove 13 of contiguous the second end 12.First end 11 has an end face 111, and one from this end face 111 vertically X be driven hole 112 towards what the second end 12 extended, in the present embodiment, the cross section that is driven hole 112 is non-circular.The second end 12 has an end face 121, and one from end face 121 installing hole 122 that extends towards first end 11 of X vertically.In the present embodiment, being driven hole 112 can be connected with the hand-held tool of ratchet spanner and so on.

Pilot pin 20 has one towards the second end 12 and be installed in mounting end 21 in the installing hole 122, and one vertically X in contrast to the ccontaining end 22 of mounting end 21.Mounting end 21 has one towards the ring of ccontaining end 22 shoulder face 211, and ccontaining end 22 has a concave face 221, and an open recess 222 that is defined by concave face 221.

Connector 30 have one towards the first socket end 31, of the second end 12 vertically X in contrast to the second socket end 32, of the first socket end 31 vertically X run through first and second socket end 31,32 and be arranged on the second socket end 32 and radially be communicated with the hole of bead 34, a ring shoulder 35 of axis hole 33, and the outer shroud caulking groove 36 of contiguous first a socket end 31 for the axis hole 33, that pilot pin 20 penetrates.Axis hole 33 has the large aperture section 331 of contiguous first a socket end 31, and a small-bore section 332 in contrast to large aperture section 331, and the hole of bead 34 is corresponding to open recess 222, and ring shoulder 35 is to be defined between the large and small aperture section 331,332.In the present embodiment, the cross section of first and second socket end 31,32 is non-circular, and the aperture in the hole of bead 34 is radially to successively decrease outwardly, the maximum diameter of hole D1 in the hole of bead 34 is not less than the diameter D of card pearl 40, and the minimum-value aperture D2 in the hole of bead 314 is less than the diameter D of card pearl 40.

Pearl 40 is installed on the hole of bead 34 card movably.

Spring 50 is that X is set on the pilot pin 20 vertically, and between the second end 12 and the first socket end 31.In the present embodiment, the both ends of spring 50 are to be connected to ring shoulder face 211 respectively and to encircle on the shoulder 35.

Sliding sleeve 60 has a barrel 61, and one center on and for the sleeve joint hole 62 of the second end 12 and the insertions of the first socket end 31 by this barrel 61.Barrel 61 has the slip end 611 that is socketed in movably on the second end 12, and one vertically X in contrast to the connection end 612 of slip end 611, connect end 612 and be set on the first socket end 31, and borrow second clasp 80 and the first socket end 31 to link together.

Sleeve joint hole 62 has the first hole section, 621, the one contiguous second hole section 622 that connects end 612 of a contiguous slip end 611, an and interstitial hole section 623 that is connected between first and second hole section 621,622, in the present embodiment, the cross section of interstitial hole section 623 is non-circular.

The first hole section 621 has the spacing ring slot part 624 of an axial width greater than first clasp, 70 thickness.The second hole section 622 has the interior ring caulking groove portion 625 that an axial width approximates second clasp, 80 thickness.The second end 12 is to extend into interstitial hole section 623 from the first hole section 621, and blocks with interstitial hole section 623 covers, and this first socket end 31 is to extend into interstitial hole section 623 from the second hole section 622, and blocks with interstitial hole section 623 covers.

First clasp 70 is installed between the spacing ring slot part 624 of the outer shroud caulking groove 13 of the body of rod 10 and sliding sleeve 60, when first clasp, 70 buckles are on outer shroud caulking groove 13, first clasp 70 is radially to extend in the spacing ring slot part 624, in case sliding stop sleeve 60 breaks away from the second end 12 of the body of rod 10.

Second clasp, 80 buckles are between the interior ring caulking groove portion 625 of the outer shroud caulking groove 36 of connector 30 and sliding sleeve 60, and the connection end 612 of sliding sleeve 60 and the first socket end 31 of connector 30 are linked together, and then make sliding sleeve 60 can drive connector 30 and card pearl 40 together synchronously.

Shown in Fig. 4,5, sliding sleeve 60 and connector 30, card pearl 40 X are vertically moved between the primary importance and a second place, and when sliding sleeve 60 was mobile between first and second position, spacing ring slot part 624 was to move with respect to first clasp 70.When sliding sleeve 60 with connector 30, when card pearl 40 moves to primary importance, the concave face 221 of pilot pin 20 props up card pearl 40, card pearl 40 is exposed to outside the hole of bead 34, on the contrary, when sliding sleeve 60 with connector 30, when card pearl 40 moves to the second place, card pearl 40 is the open recess 22 that radially are absorbed in pilot pin 20.

As shown in Figure 5, when user's desire is overlapped a sleeve 100 on the second socket end 32 that is fixed in connector 30, the user can promote sleeve 100 towards the second socket end 32, at this moment, the end face of sleeve 100 will push against card pearl 40, and force card pearl 40 and connector 30, sliding sleeve 60 moves to the second place backward, and then card pearl 40 is absorbed in the open recess 222 of pilot pin 20, then, as shown in Figure 4, the elastic restoring force of spring 50 can promote connector 30 and sliding sleeve 60 forward, moves to primary importance and drive card pearl 40 synchronously, at this moment, because the concave face 221 of pilot pin 20 has propped up card pearl 40, and make card pearl 40 outer being exposed at outside the hole of bead 34, therefore, card pearl 40 can fix with the embedding hole 110 of sleeve 100, is fixed on the second socket end 32 and sleeve 100 is firmly overlapped.

On the contrary, when user's desire when sleeve 100 is taken off in the second socket end 32, as shown in Figure 5, the user can pull back sliding sleeve 60 to the second place, and card pearl 40 is fallen in the open recess 222, and then the embedding hole 110 of deviating from sleeve 100, so, the user can take off sleeve 100 easily.

Via above explanation, can again advantage of the present utility model be summarized as follows:

The utility model moves between first and second position by sliding sleeve 60 and connector 30, card pearl 40, card pearl 40 is firmly exposed to outside the hole of bead 34, or card pearl 40 is fallen in the open recess 222, so, the user can be fixed in sleeve 100 covers on the utility model easily, or takes off sleeve 100 from the utility model easily.

Conclude above-mentioned, hand-held tool connecting rod of the present utility model, not only easy to use, more can fix or unclamp the work package of sleeve and so on apace, so can reach the purpose of this utility model really.
