Description
Technical field:
The present invention relates to the installation and removal of saw blade in a kind of electric tool, emery wheel, resin cleavage blade, belong to the electric tool special spanner and make the field.
Background technology:
The electric tool miscellaneous of Xiao Shouing in the market, the installation and removal of its saw blade, emery wheel, resin cleavage blade all need two spanners to finish with installation, one of them spanner acts on the axle of electric tool, it can not be rotated with the rotation direction of dismounting or assembly wrench, the two need act on very big power and direction opposite, just can finish the dismounting of screw or nut or install.Its weak point: the one, operation inconvenience needs two spanners to cooperatively interact; The 2nd, dangerous, when undue force or when overexerting,, easily cause personal injury if the force is used in spanner slippage operation.
Notification number 2501706, title " device of the large-scale screw nut of installation or removal ", this device is by sleeve (1), tooth rest (2), tooth rest shell (3), gear shaft (4), carrier gear (5), lining (7), gear cap (8), spanner (10) is formed, the square spigot (12) of tooth rest (2) end inserts in the square hole (14) of sleeve (1), carrier gear (5) is installed on carrier gear window (11) mouth of tooth rest (2), gear shaft (4) places the center of tooth rest (2), tooth rest shell (3) shroud tooth rest (2), the square spigot (13) of the square hole (21) of spanner (10) one ends cover cogwheel shaft (4) during use.Its weak point: the one, when this device rotates with axle, can not be used for installation or removal with screw nut, therefore can't be used for the installation and removal of electric tool.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, designing a kind of one is to need not to lock power tool shaft, can be when output axle head installation or removal workpiece fastening screw or the nut of adopting; The 2nd, not only efficient and convenient when rotating installation or removal, and also laborsaving; The 3rd, safe and reliable, under any circumstance or under the condition, all can not injure the person.
Design: in order to realize purpose of design of the present invention, on structural design: 1, the design of housing location loading and unloading face positioning boss or groove, it is one of feature of the present invention, this positioning boss match with groove or boss in the electric tool (boss snaps in the groove in the electric tool part (clamping plate) or groove inserts boss in the electric tool part (clamping plate)), not only can play the purpose that the rotating shaft of locking electric tool is not rotated with the installation or removal special spanner effectively, and absolute 100% safety, can not injure personal safety.2, housing location loading and unloading face rotor plate design at hand, it is two of feature of the present invention, this driving end not only can be effectively with screw in the electric tool or nut card jail, and under the effect of external force, match with the boss on the housing positioner face, can be like a cork by rotating, screw or nut being loaded onto or dismantled, the reliable rotation of driving end has been guaranteed in the design of housing location loading and unloading face driving end axis hole.3, housing loading and unloading plane or recessed design along the formula inner plane, it is three of feature of the present invention, because housing loading and unloading plane is big and be face and contact with saw blade, emery wheel, resin cleavage blade clamping plate (iron) in the electric tool that will load and unload, and protrude or recessed positioning boss or groove in groove and the electric tool or boss clamping on the loading and unloading plane, driving end then with the power tool shaft clamping, form 2 face contact types and rotate the installation or removal structure, not only guarantee the quick loading and unloading of screw in the electric tool or nut, and guaranteed handling safety; Secondly, the axis hole in the housing provides good assembled condition for the normal rotation of gear train again, makes the structure of product simple more, cost is lower, easier for installation, performance is more reliable.4, method with the transmission of offset distance torsion, realize the loading and unloading of axle head screw or nut, gear train constitutes offset distance by driving end axle power output gear and axle power input gear and transmits the torsion structure, or by driving end axle power output gear, one-level carrier gear and axle power input gear constitute offset distance and transmit the torsion structure, or by driving end axle power output gear, secondary carrier gear and axle power input gear constitute offset distance and transmit the torsion structure, or by driving end axle power output gear, multistage carrier gear and axle power input gear constitute offset distance and transmit the torsion structure, it is four of feature of the present invention, 1. the offset distance that is made of driving end axle power output gear and axle power input gear transmits the torsion gear train, axle power input gear and the engagement of driving end axle power output gear and strap wrenches head axle power output gear rotate, and driving end axle power output gear constitutes overall structure by gear and driving end; 2. the offset distance that is made of driving end axle power output gear, one-level carrier gear and axle power input gear transmits the torsion gear train, power shaft drives the input gear and rotates, gear wheel engagement in input gear and the carrier gear, pinion in the carrier gear and driving end gears engaged and drive driving end gear rotate, carrier gear is made of gap bridge gear wheel and gap bridge pinion, and the two rotates synchronously.The driving end gear is to constitute overall structure by gear and driving end; 3. the offset distance that is made of driving end axle power output gear, secondary carrier gear and axle power input gear transmits the torsion gear train, power shaft drives the input gear and rotates, gear wheel engagement in input gear and the folded formula carrier gear, pinion in the folded formula carrier gear and the engagement of the gear wheel in the secondary carrier gear, pinion in the secondary carrier gear and driving end gears engaged and drive driving end gear rotate; 4. the offset distance that is made of driving end axle power output gear, multistage carrier gear and axle power input gear transmits the torsion gear train, on the structural design be effective combination between 2 or a plurality of folded formula carrier gear and 2 or a plurality of carrier gear, the formation structure of its gear train can be of all kinds, but purpose is in less power of input input, output obtain one huge big, thereby easily with screw on the electric tool or nut loading and unloading.5, the driving end end is provided with the structural design of magnet, is five of feature of the present invention, this magnet can be effectively with the screw of loading and unloading or nut attached in the driving end, so that loading and unloading fast prevent that screw or nut from dropping.6, the end of driving end is through hole shape structure Design, is six of feature of the present invention, and this through hole shape driving end structure Design can satisfy that long screw passes driving end in the electric tool, nut is stayed in the driving end, guarantees the reliable operation of specific purpose tool.7, the driving end end vias around be equipped with the design of magnet, be seven of feature of the present invention, this magnet equally can be effectively with the screw of loading and unloading or nut attached in the driving end, so that loading and unloading fast prevent that screw or nut from dropping.Its technical scheme: electric tool safety special spanner, the location loading and unloading face of housing is provided with the eccentric throw strong point and driving head, the power output shaft that is arranged in the gear train of housing drives driving head and rotates, gear train constitutes offset distance and transmits the torsion structure, and the power input gear in its gear train is connected with power input shaft and drives its rotation by power input shaft.
The present invention compares with background technology, not only novel structure, principle uniqueness, profile are simple, dependable performance, and handling safety, convenience, laborsaving, realized quick, safe, laborsaving, convenient, the reliable purpose of loading and unloading of saw blade, emery wheel, resin cleavage blade in the electric tool, the effect that played that art is good for strength, solved for a long time people and wanted to solve, but still unsolved technical barrier.
