Definitions

  • the invention relates to a screwing tool according to the preamble of claim 1.
  • a screwing tool of the type mentioned is from the US 5732606 previously known.
  • a handle inserted a unilaterally open tube, which carries at its free end an actuating sleeve.
  • a captive element formed by a ball can be radially displaced in a window of the tube.
  • Inside the tube is a shaft whose free end has an actuating portion. This has a cavity for inserting a bit.
  • the bondage element holds the shaft in a storage position. If the binding element is displaced by moving the actuating sleeve into a release position, the shaft can be pulled out of the tube.
  • the shaft is flexible and has at its end portion stuck in the tube also a ring throat, in which the captive element can enter when the shaft is pulled out, not only rotationally fixed, but also axially fixed relative to the tube.
  • a certain hold also conveys a seated on the end portion spring ring, which grinds when pulling the shaft on the inner wall of the pipe over. The withdrawal requires a force application.
  • In the final phase of the home transfer of the spring ring occurs in an annular throat of the inner wall of the tube. This stop ensures that the shaft can be pulled out of the tube only by an increased force.
  • the handle has there a central cavity into which a chucking section of the blade can be inserted. Cavity opening side can there may be provided a chuck having radially against the blade engageable jaws to keep the blade tied in the axial direction.
  • a chuck having radially against the blade engageable jaws to keep the blade tied in the axial direction.
  • Chucks are also known in the art for holding bits. Chucks for bits show, for example, the DE-U1 85 02 308 . DE-U1 201 06 986.5 and the DE-U1 90 00 245.8 ,
  • Screwdrivers with interchangeable blades are known from the DE 44 01 335 C2 as well as from the DE-U1 90 02 085 ,
  • the invention has for its object to further develop the generic screw advantageously use.
  • the claim 1 provides initially and essentially that the removable shaft can also be brought into a Verwahrwolf in which a large part of the shaft is located in a rear part of the cavity and is held there by means of holding, which holding means are releasable, so that in the cavity inserting part of the shaft except for a fixed shaft end associated holding portion of the shaft can be extended by applying force from the cavity against a stop in a position of use, in which position of use, the holding section is tied by the chuck in the axial direction and in the direction of rotation. This bondage can be canceled to remove the shaft.
  • the screwing tool is not only telescopically from an operating position into a storage position and vice versa, in which two positions the shaft is held.
  • the shank carrying the screw working tip can also be removed from the handle and, in particular, exchanged.
  • the screwing tool can be stored to save space.
  • a handle associated, in the release position displaceable actuator, in particular in the form of an actuating sleeve for releasing the holding means is provided.
  • a displacement of the actuating element beyond the release position is provided which can be brought out of action.
  • the stop is spring loaded in effect brought.
  • the force for extending the shaft is applied to the position of use of a when inserting the shaft in the storage position tensioned, supported on the bottom of the cavity spring.
  • the stop is formed by at least one entering into a locking recess of the shaft end locking ball.
  • the locking ball is located in a window of the cavity wall and cooperates with a spring-loaded in the axial direction of the screw locking sleeve. It is also proposed that the locking ball in the storage position and the Extending the shank is spring-loaded in the window inlaid by a, in particular oblique edge edge of the locking sleeve in the radial direction.
  • the blocking recess may be formed as a ring throat. The axial length of the annular throat is greater than the locking ball diameter.
  • the detent ball is acted upon by a sloping edge of a spring-loaded in the axial direction of the screwing actuating sleeve.
  • An essential feature of the invention provides that the detent ball, both in the storage position and in the position of use by axially displacing the actuating sleeve releasably rests in a corner recess of the shank to bind the shaft axially.
  • Another embodiment essential to the invention provides a rear stop shoulder of the actuating sleeve of the axial displacement of the actuating sleeve displaces the locking sleeve of its locking position into a radial deflection of the locking ball enabling release position.
  • the stop shoulder is formed by a ring of the operating part of a sleeve associated compression spring, in the cavity in the release position, the locking ball can escape. It can also be provided that the locking sleeve is supported in the locking position against a collar, which is the abutment of the actuating sleeve spring.
  • the grip cavity is formed by a pipe receiving the shaft with a polygonal cavity which forms the windows for the blocking ball and the detent balls. The diameter of the detent ball is smaller than the diameter of the detent ball.
