Abstract
The utility model relates to a chain driven wrench and is characterized in that an end of a wrench body is provided with a clamp support, a clamp gear is arranged on the clamp support by a bearing, a bolt or a nut clamp is arranged in the port of a gear shaft, a cranking bar support is arranged on other end of a body, a cranking bar gear is arranged on the cranking bar support by a rotating shaft, the rotating shaft is provided with a rotating handle, and a loop chain is meshed with a clamp gear and the cranking bar gear to form a transmitting portion. The cranking bar gear is driven by a rotating handle for rotation. The clamp gear and the clamp on other end of a long arm are driven by the chain transmitting portion, which realizes the assembly and disassembly of the bolt or the nut. A assembling and disassembling clamp is horizontally arranged on one end of the wrench, which could deeply extend into a narrow slit. The utility model which adopts the chain transmitting portion structure transmits the manual force to the clamp for assembling and disassembling the bolt or the nut, which has the advantages of simple structure and convenient use, and solves the problem of the prior wrench for the impossible use in the narrow slit.
Description
Technical field
The utility model discloses a kind of chain-type and drives spanner, and the assembling that is used for bolt, nut is installed, and belongs to the hardware ﹠ tools technical field.
Background technology
In building material industries such as section bar door and window, by door and window is made in section bar combination assembling, often need be in the space of narrow gap construction bolt, realize the combination assembling, therefore, the five metals spanner of existing plank frame is difficult to reach pulls assembling bolt in the slit, can't be applicable to the assembling of section bar door and window.
Summary of the invention
The utility model provides a kind of chain-type to drive spanner, and having solved common wrench can't be in the shortcoming of narrow space use.
Technical solution of the present utility model is as follows: an end of wrench body is provided with the jig support, the jig gear by the gear shaft device on the jig support, bolt or nut jig are embedded on the gear shaft port, the other end of body is provided with the rocking handle support; the rocking handle gear by turning gear on the rocking handle support; rotating shaft is provided with turning handle, and ring chain and jig gear, rocking handle gears engaged constitute transmission, also is fixed with on long-armed and controls handle.
Above-mentioned wrench body can be made flexible long-armed structure.
When the utility model used, turning handle drove the rocking handle gear and rotates, and rotated by secondary jig gear, the jig that drives the long-armed other end of chain drive, realized the loading and unloading of bolt or nut.
Good effect of the present utility model is: the loading and unloading jig is an end that is horizontally set on spanner, can be deep into the space of narrow gap, adopt the chain drive auxiliary structure, manual force is passed to jig, realize the loading and unloading of bolt or nut, have simple in structurely, easy to operate, overcome the shortcoming that common wrench can't be used operation at narrow space.
