Through the above technical solutions, rotation drop handle, drives rotor plate rotation, is caught in kelly in card slot, rotor plate and mentions The position of ring is then fixed, convenient for being lifted shell by drop handle；If desired it is stored, then by pulling kelly, makes kelly It leaves in card slot, then rotates drop handle, be accommodated in drop handle in lifting slot.The drop handle that the utility model is used in extraction shell can Rotation is accommodated in accommodating groove, convenient for storing to the utility model, reduces the space occupied required for storing, drop handle storage It damages outside shell in shell, can effectively avoid drop handle；The utility model is when storing drop handle, kelly and rotor plate It abuts, when effectivelying prevent storage, drop handle rotates in accommodating groove.

Further, the shell offers resettlement groove in the kelly side, be provided in the resettlement groove with it is described Kelly co-axially fixed connection sheet is additionally provided with elastic component in the resettlement groove.

Through the above technical solutions, elastic component provides elastic force for connection sheet, when rotor plate rotates, kelly is pushed away connection sheet Under dynamic, it is caught in card slot automatically, the position of rotor plate is fixed.

Further, control flume, the control flume are offered far from the side of the rotor plate in kelly in the shell Interior rotation is provided with control-rod, and the control-rod is hinged close to one end of the kelly and the kelly.

Through the above technical solutions, control-rod is used to drive the movement of kelly, kelly is pulled out out of card slot, convenient for rotation Drop handle.

Further, close to one end of the kelly, rotation is provided with idler wheel, the idler wheel side and institute to the control-rod State control flume slot bottom abutting.

Through the above technical solutions, idler wheel is used to support at the rotation connection of control-rod and kelly, avoid control-rod to card After bar applied force, kelly is bent.

Further, the control-rod surface is equipped with shaft through waist hole is offered in the waist hole, the shaft Both ends are both secured to the control flume opening.

Through the above technical solutions, the cooperation between waist hole and shaft, had both been able to satisfy the rotation of control-rod, moreover it is possible to make to control Bar is moved up and down with respect to shaft, so that control-rod is accommodated in control flume.

Further, the two sides of the rotor plate are embedded with the first magnetic stripe, are embedded in the accommodating groove and described first The second magnetic stripe that magnetic stripe attracts each other.

Through the above technical solutions, the attraction between the first magnetic stripe and the second magnetic stripe, is located at water for enhancing rotor plate Stability when prosposition is set is effectively prevented from storage, and drop handle rotates in accommodating groove.

Further, the drop handle side winding is provided with Anti-slip cover.

Through the above technical solutions, Anti-slip cover is used to enhance the frictional force between manpower and drop handle, prevent from falling off.

Further, the rotor plate is set as inclined surface at the close card slot.

Through the above technical solutions, inclined surface with kelly for abutting, kelly slides into card slot on inclined surface.

Compared with prior art, the beneficial effects of the utility model are as follows：

(1) drop handle for extraction is arranged in the utility model outside shell, and can be rotated drop handle and be accommodated in accommodating groove, The space occupied required for storing is reduced, drop handle is can effectively avoid and damages outside shell, in addition, rotation control rod can be by kelly It is taken out out of card slot, stowing operation is very convenient；

(2) when the utility model is stored, rotor plate is abutted with kelly, and kelly drives control-rod rotation, while making control-rod It is accommodated in control flume, reduces storage occupied space；

(3) by rotating setting idler wheel at the rotation connection between control-rod and kelly, using in idler wheel and control chamber The abutting of wall offsets the component of control-rod vertical direction, and the power transmitted along control-rod is effectively avoided to bend kelly.
