Tool holding device

The invention discloses a tool holding device which structurally comprises a first holding tool, a fixer, a fixing supporting column, a second holding tool, a disassembling mechanism, a locking screwrod, a tool member, a shell and a chamber. The fixing supporting column is fixed on the rear portion of the fixer through a screw. The fixer is fixed to the center of the rear portion of the disassembling mechanism through a rivet. The disassembling mechanism is provided with a linkage mechanism, a starting mechanism, a pushing mechanism, a heat-dissipating mechanism, a telescoping mechanism, a transmission mechanism, a pulley mechanism and a metal frame. The tool holding device has the beneficial effects that by means of the arranged disassembling mechanism, when staff take down the holding device, the equipment for fixing the holding device only needs to be loosened through the parts in the disassembling mechanism, disassembling is convenient, a great deal of time is saved, multiple working faces of multiple hol
