Embodiment
As Fig. 1, Fig. 2, Fig. 3, the compound bar that slips of the utility model comprises:
One extension bar 10;
One axially is located at the pin-and-hole 11 of these extension bar 10 1 ends;
One knock pin 20 closes the footpath and is located in this pin-and-hole 11, establishes a spring 21 between at the bottom of pin end and the hole; The pin body of these knock pin 20 nearly these springs 21 is established an oblique duct 22; This knock pin 20 is established a card pearl groove 23 away from the pin body of this spring 21, this card pearl groove 23 comprises first and second groove position 24,25, this first and second groove position 24,25 is to be parallel to the axle direction arrangement connection of this knock pin 20, and the groove depth of the first groove position 24 is greater than the second groove position 25, two groove positions, 24,25 intersections form an inclination interface 26, and the second groove position 25 has at the bottom of the planar slot 27;
One pressure head 30, its body portion establishes a kerf 31, and this otch 31 makes this formation one of pressure head 30 body portions and the parallel relative inclined-plane 32 of 22 1 side opening walls, above-mentioned oblique duct; This pressure head 32 is located in the pressure head hole 12 on these extension bar 10 bar walls, and these inclined-plane 32 ends stretch in the oblique duct 22 of this knock pin 20, and the other end protrudes outside this pressure head hole 12;
One card pearl 40 is located in the hole of bead 13 of these extension bar 10 bar walls, and its relative this knock pin 20 partly pearl bodies is positioned at this card pearl groove 23.
As Fig. 3, this knock pin 20 is subjected to these spring 21 elastic force effects and is positioned at a position of rest, and protruding this pressure head hole 12 of exposing of these pressure head 30 1 ends becomes the part that can be pushed by the user.These pressure head 30 the other ends stretch into the opening end in these knock pin 20 oblique ducts 22, it is inclined-plane 32 and this partly hole wall applying of oblique duct 22 partly, in view of the above, this inclined-plane 32 forms with this oblique duct 22 interferes, and this pressure head 30 can't break away from along the hole axle direction in this pressure head hole 12.Moreover this card pearl 40 is positioned at this second groove position 25, is subjected at the bottom of this planar slot 27 pushing and pressing, and its some is protruded from outside this hole of bead 13.
As Fig. 4, this pressure head 30 is depressed, this inclined-plane 32 forms mutual cunning with these oblique duct 22 1 side opening walls and pushes away effect, make pressure head 30 toward extension bar 10 inner moving, this knock pin 20 moves toward the direction of this spring 21 of compression, therefore makes the first groove position 24 with respect to this card pearl 40, because the groove depth of the first groove position 24 is dark than the second groove position 25, this card pearl 40 is subside in the first groove position 24, therefore recesses this extension bar 10 surfaces.So far, this extension bar 10 can wear links 50 such as a tool head, conversion adapter or extension rod in its end.
As Fig. 5, discharge this pressure head 30, this spring 21 release can, promote this knock pin 20 and move toward aforesaid position of rest, these oblique duct 22 1 side opening walls and this pressure head 30 inclined-planes 32 interaction effects make this pressure head 30 up mobile and protrude this pressure head hole 12.Simultaneously, inclination interface 26 in this card pearl groove 23 promotes this card pearl 40, make its part beading protrude this hole of bead 13 outer snapping in the pearl groove 51 of above-mentioned link 50, the second groove position 25 and 27 to replace this card pearl 40 at the bottom of its planar slot, can not fall into moving when this card pearl 40 is born link 50 combination power to card pearl groove 23, card pearl 40 is stable, can promote the stability that combines of extension bar 10 and link 50.
As Fig. 6, Fig. 7, an end of the utility model extension bar 10 sheathed above-mentioned links 50 is a connecting end 14, and the other end is working end 15, and this working end 15 is the tube-in-tube structure of diameter greater than these extension bar 10 bodies.
The degree of depth in above-mentioned second groove position 25 of the utility model and oblique duct 22, when this pressure head 30 was pressed, this card pearl 40 and pressure head 30 can fully submerge in this pressure head hole 12 and the hole of bead 13, and its upper limb is lower than extension bar 10 surfaces and does not protrude.In view of the above, a suite of tools 52 is positioned on extension bar 10 shafts by this pressure head 30.
Above-mentioned suite of tools 52 has an extension bar fit portion 53 and an instrument fit portion 54, and this extension bar fit portion 53 establishes a hole of radially running through 531 and closes the footpath for these extension bar 10 shafts and be through at wherein, and this instrument fit portion 54 can be in conjunction with a tool head 55 (for example, sleeve).In view of the above, this extension bar 10 is with suite of tools 52 and intersects vertically, and this extension bar 10 can grip for the operator, and brings into play the effect of similar long handle spanner, allows the operator drive this suite of tools 52 more effortlessly.The utility model more provides the section 101,102,103,104 of one or more tool on-slip effect on extension bar 10 shafts, performance on-slip effect when the operator grips.
As Fig. 8, this suite of tools 52 will can not broken away from this extension bar 10 by the block of this pressure head 30 and hole enlargement working end 15.This suite of tools 52 can be by being moved to by the second place of these 15 blocks in hole enlargement working end by the primary importance of 30 blocks of this pressure head, and form one section displacement distance L.This suite of tools 52 more can be terminated in arbitrary position among this displacement distance L surely.
Though the utility model is to do explanation with a most preferred embodiment, is skillful in this skill person and can makes various multi-form changes not breaking away under the utility model spirit and the category.Above illustrated embodiment is only in order to explanation the utility model, and is non-in order to limit the scope of the utility model.Such as do not disobey various modifications or the variation that the utility model spirit is engaged in, all belong to the utility model claim.
