The specific embodiment
Present embodiment is an example with two cover hand fastening drill clutch, and the internal structure of drill chuck can adopt the internal structure of various hand fastening drill clutch.
With reference to accompanying drawing 1,3,5.The utility model comprises drill body 1, jaw 4, and the drill body front end is provided with holder 10, and holder has the opening 7 that passes for jaw, and the outer wall of holder is provided with the detent 10-1 that cooperates with the hydraulic quick coupler of instrument.This opening passes when certainly, also can be advanced and retreat for jaw simultaneously.
Shown in Fig. 1,3,5, the front end of described drill body is provided with a step 1-1, and holder 10 is fixed on the step.Detent 10-1 is an arc groove, evenly is distributed with three arc grooves on the outer wall of holder.
The rear end 6 of described holder protrudes from the front end cylindrical of drill body, and this protrudes the position to rotary sleeve 2 axial limitings.
Described hydraulic quick coupler comprises fittings body 12, fittings body is provided with several holes of not drilling 5 corresponding with detent 10-1, be provided with ball 8 in the hole, described hydraulic quick coupler also is provided with pulling cover 11, pulling cover inwall be provided with steel ball give up the throne groove 3 and with the corresponding boss 11-2 in hole that places steel ball, fittings body and pulling are provided with spring 11-3 between overlapping.Give up the throne and have transition inclined-plane 13 between groove and the boss.
The mode of spring 11-3 is set between fittings body and the pulling cover, can be that spring 10 is directly arranged between fittings body and the pulling cover, also can be between the member that spring 11-3 is located at and fittings body or pulling cover are fixedly connected, present embodiment has adopted the latter's structure, and drawing reference numeral 9 is the member of fixedlying connected with fittings body.As shown in Figure 1, by the restriction of configuration on spring and the fittings body, make pulling be enclosed within interior slip of certain distance on fittings body surface.
