Detailed Description

The invention will be further described with reference to the following figures and examples:

example 1: a bent screwdriver, see fig. 1-5.

Including tool bit 3, connector 2 and bull stick 1, connector 2 swing joint is in on the 1 tip of bull stick, the other end and the tool bit 3 of connector 2 are articulated, tool bit 3 can rotate at 2 tip of connector.

The utility model discloses a rotary rod, including the rotary rod, 2 connecting grooves 201, connecting groove 201, spacing hole 205, first spacing hole 205 run through connector 2 and perpendicular connecting groove 201 setting, tool bit 3 can insert in the connecting groove 201, can insert recess 202 through protruding 101 through the magnetism coating that sets up, makes the two difficult separation owing to the effect of magnetic force, and then uses when rotating more conveniently, the end of 1 both ends of rotary rod is regular hexagon, 1 both ends of rotary rod tip is equipped with the magnetism coating respectively, 2 one end of connector is interior regular hexagon recess 202, the tip of rotary rod 1 can match and insert in the recess 202, 2 other end tip of connector are equipped with spread groove 201 along the axis direction run through connector 2 tip, spread groove 201 lateral wall is equipped with first spacing hole 205.

3 one end of tool bit is equipped with connection piece 301, connection piece 301 center department is equipped with the spacing hole of second, still includes connecting rod 203, tool bit 3 and connector 2 pass through connecting rod 203 and articulate, and its 3 other ends of tool bit are screwdriver 302, and connecting rod 203 through setting up is connected spread groove 201 and connection piece 301, and tool bit 3 can carry out the free rotation around connecting rod 203, and then adjusts the angle of screwdriver tool bit 3 for this design application range is more extensive.

Still include that a plurality of sets up the spacing groove 205 on the inside wall of spread groove 201, spacing groove 205 is the arc, spacing groove 205 is circular array along connecting rod 203 axis direction and arranges, still including setting up spacing arch 101 on connection piece 301, protruding 101 size and quantity with spacing groove 205 phase-match can make tool bit 3 give rotation direction resistance when rotating round connecting rod 203 through the spacing groove 205 that sets up and the cooperation of spacing arch 101 to can make can not appear when using this design to twist the screw because of the pin joint rotates and lead to the condition of unable screw of twisting.

The limiting protrusion 101 is made of an elastic material, the elastic material is rubber, resistance in rotation can be provided when the cutter head 3 is rotated through the arranged rubber protrusion 101, the rotating angle is kept, and the swinging cannot be caused by gravity.

In particular use: the screwdriver bit 3 matched with the screwed screw cap is taken out, the connecting piece 301 on the screwdriver bit 3 is inserted into the connecting groove 201, then the connecting rod 203 sequentially penetrates through the first limiting hole 204 and the second limiting hole to limit the connecting piece 301 in the connecting groove 201, and therefore the connection of the screwdriver bit 3 is completed.

Because the existence of its spacing arch 101 can produce the resistance when reinserting, push hard this moment, insert connection piece 301 in spread groove 201, at the in-process of inserting, the spacing arch 101 of rubber receives extrusion deformation, and then arrange spacing arch 101 extrusion in spacing groove 205, the spacing arch 101 of rubber resumes its relative rotation of connection piece 301 and spacing groove 205 and then limits the rotation of tool bit 3 because of being located spacing groove 205 and recovering self state this moment.

Then the end of the rotating rod 1 is inserted into the end of the connector 2, and the connector 2 can be adsorbed on the rotating rod 1 due to the arrangement of the magnetic coating.

After the mounting is finished, the angle of the tool bit 3 is adjusted to start the dismounting of the screw.

In addition, the end part of the rotating rod 1 can be used as an inner hexagonal screwdriver, and the other end of the rotating rod can be twisted through an additional twisting rod, so that the torque of the rotating rod is increased.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
