Holding device for holding tubular items

Abstract

A holding device includes a U-shaped base fixed on a wall and including a first protrusion and a second protrusion. A receiving space is defined between the two protrusions. The first protrusion has a hole defined in an inside thereof and a clamping member is eccentrically received in the first protrusion and a part of the clamping member is movably extended through the hole and protrudes into the receiving space. A shank of a tool is received in the receiving space and clamped by the clamping member and the second protrusion.

1 . A holding device comprising: 
 a U-shaped base with a first protrusion and a second protrusion and a receiving space defined between the protrusions, the first protrusion having a hole defined in an inside thereof and a clamping member longitudinally received in the first protrusion, the clamping member having an eccentric shaft which has a first end connected to the first protrusion and a second end of the eccentric shaft connected with a torsion spring, the clamping member having a part movably extending through the hole and protruding into the receiving space.    
   
   
       2 . The holding device as claimed in  claim 1 , wherein the clamping member has a friction band wrapped thereto.  
   
   
       3 . The holding device as claimed in  claim 1 , wherein a plurality of friction strips extend from an inside of the second protrusion.  
   
   
       4 . The holding device as claimed in  claim 1 , wherein the base includes a hook member on a transverse board located at a rear end of the base, a projection extending from the eccentric shaft, one end of the torsion spring hooked to the hook member  16  and the other end of the torsion spring engaged with the projection.  
   
   
       5 . The holding device as claimed in  claim 1  further comprising a back board which is adapted to be fixed on a wall and two threaded reception tubes extending from the back board, two guide tubes extending from a transverse board located at a rear end of the base, two bolts extending through the guide tubes and connected with the reception tubes.  
   
   
       6 . The holding device as claimed in  claim 1  further comprising two connection plates connected to two guide tubes extending from a transverse board located at a rear end of the base, two reception frames adapted to be fixed on a wall and each having U-shaped receiving space in which respective one of the two connection plates is engaged.  
   
   
       7 . The holding device as claimed in  claim 1 , wherein the eccentric shaft includes a longitudinal slot and one end of the torsion spring is engaged with the slot, a hook member is connected on a transverse board located at a rear end of the base, the other end of the torsion spring hooked to the hook member.  
   
   
       8 . The holding device as claimed in  claim 1 , wherein the base includes a transverse board located at a rear end thereof and a peripheral wall extends from the transverse eccentric shaft, the second end of the eccentric shaft of the clamping member is enclosed by the peripheral wall, a cover connected to the peripheral wall so as to prevent foreign objects from entering the space enclosed by the peripheral wall.  
   
   
       9 . The holding device as claimed in  claim 8 , wherein the peripheral wall includes a recess defined in an inside thereof and the cover includes a protrusion which is engaged with the recess.
