The beneficial effect who so sets up is: set up like this, set up the dismantlement groove and set up the reference column in the dismantlement groove at the head of bolt, when dismantling, insert and dismantle the handle, dismantle the operating head of handle and dismantle groove grafting cooperation, make the mounting groove on the operating head aim at the storage tank, and through the permanent magnet with reference column part suction and with the mounting groove grafting cooperation, thereby rotate the messenger dismantling the handle, can act on the reference column through the mounting groove with the effect, thereby realize the pivoted drive to the bolt, realize dismantling the action, here dismantle the groove as preferred circular slot, be difficult to dismantle the handle cooperation with the conventionality, the structure is simple, be difficult to the imitation, and do benefit to the realization, good result of use has

As a further setting of the utility model, the mounting groove inner wall is provided with a plurality of protruding muscle of contradicting.

The beneficial effect who so sets up is: through setting up like this, make the cooperation of mounting groove inner wall and reference column more be the fastening, difficult not hard up, increase friction between them, the power of being convenient for has good result of use.

As a further setting of the utility model, mounting groove and reference column clearance fit.

The beneficial effect who so sets up is: through setting up like this for the reference column can be more convenient entering mounting groove, guarantees the convenience of follow-up operation.

As the utility model discloses a further setting, dismantle the irregular setting of groove outline, the operating head outline with dismantle groove outline looks adaptation.

The beneficial effect who so sets up is: through setting up like this for it is inseparabler to dismantle the handle and the bolt cooperation, and the operation is more convenient, increases the imitative degree of difficulty.

As the utility model discloses a further setting, it is protruding to dismantle groove central point puts and is provided with the location, the protruding outline irregular setting in location, the overhead complex cooperation groove of pegging graft that is used for with the location of being formed with of operation.
