Abstract

The utility model discloses a single hand-operated, quickly rotatable tool handle which is used as a small tool handle for the handwork. When the tool handle is provided with various working parts of different types and specification, the utility model can be driven by the man power and can have the features of one-handed performance and continuous labor saving, so the utility model can be used as a screwdriver, a nut assembly and disassembly tool, a hole drilling tool, etc.

Description

Single hand-operated, quickly rotatable tool handle

The small instruments and tools handle of using when the utility model is handwork.

The screwdriver of existing loading and unloading screw has electrodynamic type, pneumatic type and manpower drive-type.Electrodynamic type and the general cost of pneumatic type screwdriver be than higher, and need power source; Though the common screwdriver of manually driven is cheap, do not need other power source, will spend operator's big strength in the work, and the purpose action can not be continuous, influenced work efficiency.More obvious when having a large amount of screws to load and unload especially.Existing telescopic nut wrench except that cost is higher, generally also needs two hands to operate simultaneously, and existing manpower drives boring bar tool, also needs two hands to operate simultaneously, and this bimanualness brings some inconveniences through regular meeting to the operator.

The purpose of this utility model provides a kind of manually driven can and can bore the manufacturing handle for tool simple, with low cost of small-sized hole with the loaded and unloaded screw of the continuous laborsaving operation of one hand, nut.

The main part of handle for tool is done engrail with rigid material (for example mild steel).Two end parts are on same axis.Two strap saw dentation fringe length are definite like this: can form bigger moment, can make things convenient for holding of hand again.The handle for tool main body is rotated under external force for convenience, and having installed one at an end of handle for tool main body can be around the supporting member of handle for tool main body axis rotation.The size of supporting member and shape are advisable cosily to be held in the operation palm.In order to use various workpieces such as crewdriver attachment, drill bit etc. easily, the other end of handle for tool main body should be made the structure of easy loading and unloading parts, in the utility model, has adopted simple nuts double-screw bolt locking mechanism.For laborsaving in the handle for tool operation, make hollow sleeve with the hard material that is fit to and be inserted in operation part on the handle main body.The hollow aperture is slightly larger than the diameter that is inserted in part.Consider that the instrument that is made of the utility model may be used in some charged occasion, aforementioned hollow sleeve can be made with insulating materials.Non-needs when working in order to reduce workpiece move, and at an end hollow elasticity connector and the hollow sleeve of loading and unloading parts, hollow elasticity connector one end can be combined on the handle for tool easily, also can take off easily; The other end is connected with hollow sleeve.

Compare with the similar tools of more existing energy continuous operations, the utility model possesses some outstanding advantages so at least: simple in structure, easy to manufacture, with low cost; Laborsaving, continuous operation does not have useless action, improves work efficiency; Can carry out three kinds of inhomogeneous operations.

Below, with reference to an embodiment of the present utility model, accompanying drawing is done an explanation: 1 is said handle for tool main body among the figure.The 2nd, the anchor clamps of loading and unloading parts.The 3rd, can be around any supporting member that rotates of A-A axis.The 4th, can be around the movable sleeve (when the utility model was used in livewire work, it was an insulation sleeve) of B-B axis rotation.The 5th, the connector of pad main body 1 and supporting member 3, connector can be bearing, also can be that spheroid connects.6 and 7 is to prevent 4 retainers that slide.The 8th, Flexible Connector.The 9th, anti-displacement sleeve.

Except supporting member 3 and movable sleeve 4, remaining parts all is the irony part among the figure.Special needs to be pointed out is: angle generally should be less than 15 ° between AA axis and BB axis.The utility model is used for big moment occasion, and angle should be got big value, otherwise then gets the small value, to accelerate operating efficiency.

In the practicality, the utility model should be equipped with cover workpiece such as a various screwdriver, nut sleeve, hole drill etc.During use, get a workpiece such as a screwdriver that needs, inject in the loading and unloading clamp 2 by the mesopore of anti-displacement cover 9 and the mesopore of resilient coupling 8, tighten anchor clamps with fixing screwdriver on handle for tool.Then, supporting member 3 places a certain centre of the palm, and surplus finger pinches movable sleeve 4, does circular motion with wrist, can load and unload screw continuously effortlessly.Above the using method of all the other workpieces is same.

Claims

1, a kind of singlehanded manually turn pad of the masterpiece power of choosing, by the pad main body, place pad main body one end the anchor clamps that are used to clamp workpiece, place can forming of the pad main body other end around the supporting member of a certain axis rotation of pad main body, it is characterized in that: the pad main body is single zigzag, the two ends of main body are on same axis, and main body one end has the supporting member of a suitable shape and size.

2, pad as claimed in claim 1 is characterized in that an end of pad main body has a cover to load and unload the anchor clamps of workpiece, and said anchor clamps are the nut bolt structure.

3, pad as claimed in claim 2 is characterized in that connecting on the anchor clamps hollow elasticity spare, links to each other with hollow cylinder spare at its other end, and hollow cylinder spare matches with elastic component.

4, pad as claimed in claim 3 is characterized in that having on the pad main body movable sleeve that can rotate around specific axis, and this movable sleeve can be made by insulating materials.
