Description
Technical field
The invention belongs to hand tools technical field more particularly to a kind of no dead angle spanners.
Background technique
Spanner is a kind of common installation and removal tool, is the craft that bolt, screw, nut are twisted using lever principle
Tool, there are many type and patterns, need to select corresponding spanner according to the characteristics of fastener fastened.But the prior art
In, it regardless of the spanner of form, is all greatly limited in use by operating space, so that mechanical equipment exists
Structure design and operation require aspect that the operability problems during assembly or disassembly all must be taken into consideration, due to existing spanner
Structure requires more harshness to operating space, therefore for the complicated machineries device such as vehicle, overhauls extremely difficult, work
Industry is at high cost, and the time is long.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of no dead angle spanner, uses articulated type drive mechanism, can
Sleeve is put in narrow space and is connect with fastener, then sleeve is delivered torque to by articulated drive mechanism, it is real
Fastener is dismounted in present small space, reduces operating cost, improves operating efficiency.
It is of the invention without dead angle spanner, including sleeve, joint shaft and shell；The joint shaft includes sequentially connected multiple
Shaft is connected by pin shaft between two neighboring shaft, mutually in 90 ° between two neighboring pin shaft；The sleeve and joint shaft are most
The shaft of front end is fixedly connected, and sleeve is equipped with interior hexagonal groove, and is magnetic, and magnetic adsorptive power can be utilized corresponding spiral shell
Bolt, nut are sucked, and prevent from falling；The shell includes the rigid axle sleeve being sleeved on outside each shaft and is connected to two neighboring
Metal stereotypes hoses between rigid axle sleeve；Bearing is installed, when use utilizes gold between rigid axle sleeve and shaft on the inside of it
Belong to the deformable function of stereotypes hoses and joint shaft, realizes the torque transmitting in narrow space, while metal stereotypes hoses exist
There is certain moulding ability after bending, be able to maintain certain shapes, provide reliable structure basis for joint shaft and sleeve.
Further, the shaft of the rearmost end of the joint shaft is fixed with an operating head；The operating head be and sleeve phase
In addition matched hexagon head structure can be controlled the rotation of operating head using a spanner, meet existing operating habit, can also incite somebody to action
Multiple no dead angle wrench combinations use, and practicability is stronger.
Further, between the rigid axle sleeve and sleeve of the front end of the shell and the rigid axle sleeve of the rearmost end of shell
It is to be rotatably assorted and pass through respectively rotation skeleton oil seal between operating head, reliable protection can be played to joint shaft and is made
With, avoid in use process because collision deformation or greasy dirt, impurity etc. influence pin shaft transmission performance, prolong the service life.
Further, it is filled with lubricating grease between the shell and joint shaft, guarantees the greasy property of interior of shell component, really
Protect service performance.
Further, the joint shaft further includes shaping metal bar, and the shaping metal bar is through each shaft and pin shaft
Center, and be rotatably assorted with each shaft and pin shaft, by the way that shaping metal bar is arranged, it can more reinforce the energy that joint shaft keeps shape
Power, operability are stronger.
The beneficial effects of the present invention are: no dead angle spanner of the invention, uses articulated type drive mechanism, can stretch sleeve
It is connect in into narrow space with fastener, then sleeve is delivered torque to by articulated drive mechanism, realized narrow
Fastener is dismounted in space, reduces operating cost, improves operating efficiency.
Detailed description of the invention
