Detailed description of the invention

As shown in Figure 1, Figure 2 and Figure 3, a kind of Anti-fall screwdriver that the utility model provides, is made up of cutter head 1, knife bar 12 and handle of a knife 13, knife bar 12 is arranged with socket part 3.Socket part 3, when without External Force Acting, can be fixed on knife bar 12; When applying the external force along knife bar 12 axis, socket part 3 can be moved along knife bar 12.

Continue composition graphs 1 to Fig. 3, radially relative both sides, socket part 3 are articulated with two grip blocks 2 by articulated section, two grip blocks 2 are oppositely arranged along knife bar 12 length direction, two grip blocks 2 all bend to cutter head 1 direction near one end of cutter head 1 and the other end be combined to form for clamping part 4, two grip blocks 2 of clamping screw 6 (see Fig. 6) all tilts from articulated section to the direction that described knife bar 12 is contrary and forms splay press section 5.By relatively pressing press section 5 towards knife bar 12 direction, grip block 2 can be made to rotate and drive clamping part 4 to open.

Aforementioned articulated section can use various structures to realize, and is only specifically described a kind of structure wherein in conjunction with the present embodiment herein.As shown in Figure 4, this articulated section comprises the inverted impulse body 82 be arranged on press section 5, the otic placode 81 be relatively arranged on socket part, pivot 83 and torsion spring 84.Inverted impulse body 82 is articulated by pivot 83 and otic placode 81, and torsion spring 84 is set on pivot 83, and its one end is fixed on otic placode 81, and the other end is fixed on inverted impulse body 82.When press section 5 is not subject to External Force Acting, by the effect of torsion spring 84, two clamping parts 4 can be made to remain closure state.

As a kind of preferred version of the present embodiment, the knife bar 12 of both sides, socket part 3 is provided with spacing collar 91 for limiting socket part 3 moving range and spacing collar 92.Spacing collar 91 and 92 is fixedly located on knife bar 12.Spacing collar 91 can prevent socket part 3 from coming off from knife bar 12.When socket part 3 is moved to handle of a knife 13 direction and abuts against spacing collar 92, clamping part 4 can retreat to knife bar 12 both sides and cutter head 1 is exposed.In use, only need socket part 3 is moved to handle of a knife 13 direction and abuts against spacing collar 92, cutter head 1 can be made to expose clamping part 4, be convenient to the position that user adjusts clamping part 4.

As another preferred version of the present embodiment, one end that clamping part 4 is relative all offers semicircular groove 7 make-up of semicircular groove 7, two and forms the circle suitable with screw 6, thus makes clamping part 4 more stably clamp screw 6.

Grip block 2 in the present embodiment, clamping part 4, press section 5, socket part 3 and spacing collar 91,92 all adopt steel to make, and to improve firmness degree and the durability degree of instrument, certain above-mentioned each parts also can adopt other materials to make.

When installing screw, as shown in Figures 5 and 6, pressing press section 5 makes clamping part 4 open relatively, is placed on cutter head 1 by screw 6, unclamps press section 5 and makes clamping part 4 closed and be fixed in groove 7 by screw 6.Rotate handle of a knife 13 afterwards to be screwed into screw 6.Screw 6 is screwed into a certain degree (no longer shaking), again relatively pressing press section 5 makes clamping part 4 open, socket part 3 is moved to handle of a knife 13 direction and abuts against spacing collar 92, make clamping part 4 retreat to knife bar 12 both sides and expose cutter head 1, unclamp press section 5 clamping part 4 is closed and abuts against on knife bar 12, avoid clamping part 4 to affect the fastening installation of screw 6.Continue to rotate handle of a knife 13 with tighten the screws 6.

When unloading screw, first pressing press section 5 and clamping part 4 is opened, socket part 3 moved to handle of a knife 13 direction and abuts against spacing collar 92, make clamping part 4 retreat to knife bar 12 both sides and expose cutter head 1, unclamping press section 5 and clamping part 4 is closed and abuts against on knife bar 12.Rotate handle of a knife 13 afterwards and screw 6 is screwed onto loosening state.Pressing press section 5 makes clamping part 4 open, and is moved in the direction of socket part 3 to cutter head 1, and makes clamping part 4 exceed cutter head 1.Unclamp press section 5 make clamping part 4 closed and screw 6 is fixed in groove 7.Continue to rotate handle of a knife 13 and unscrew screw 6 until it is backed out completely.

By the structure of above-mentioned specific embodiment, following benefit can be obtained:

2. the utility model structure is simple, the easy to use and manufacturing.
