Description
Technical field
The utility model relates to a kind of spanner, and specifically the adjustable antioverloading box spanner of a kind of multipurpose load, belongs to machine tool technical field.
Background technology
Often need to use box spanner to dismantle bolt, nut in machine work and fastening.In production and life, widely used bolt, nut are mostly regular regular polygon structure at present, because workmen dismantles at use box spanner bolt, nut and is difficult to control moment exactly in fastening process, often easily exceed bolt, maximum moment that nut can carry, the corner angle on bolt, nut outer wall are caused to damage, cause spanner to skid, bring unnecessary trouble to machine work.
Although at present the digital torque spanner produced and use in life can measure exactly and read bolt, moment that nut carries, due to the expensive and poor reliability of digital torque spanner, cannot use in machine work on a large scale.Therefore can effectively prevent moment excessive in the urgent need to a kind of and cause the box spanner that bolt, nut damage.
Be incorporated herein the applicant 201320689180.X patent, which disclose a kind of antioverloading box spanner, although this technical scheme can effectively prevent because moment is excessive and cause bolt, nut to damage, but the moment of its load can not flexible modulation, therefore has certain limitation.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, and can effectively prevent moment excessive and the adjustable antioverloading box spanner of multipurpose load that is that cause bolt, nut to damage.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the adjustable antioverloading box spanner of a kind of multipurpose load, comprise handle, connecting rod, circular hole, screw hole, trip bolt, spring, collet head, annular groove, latch, pin hole, socket, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, connecting rod is provided with circular hole, the lower end of connecting rod is provided with screw hole, trip bolt is provided with in screw hole, spring and collet head is provided with in circular hole, collet head is provided with annular groove, trip bolt is after through the screw hole being arranged on connecting rod lower end in embedded rings connected in star, collet head is provided with pin hole, latch is provided with in pin hole, connecting rod is provided with socket, latch is successively through the socket be arranged on connecting rod and the pin hole be arranged on collet head, collet head is locked in connecting rod.
The length of described latch is greater than the degree of depth of described pin hole.
The drift of described spring is greater than the length of described collet head.
The profile of described handle, connecting rod is cylindrical structural.
Described trip bolt is after through the screw hole being arranged on connecting rod lower end in embedded rings connected in star, and effect is fixed in circular hole by collet head.
The width of described annular groove is greater than the diameter of the screw rod of described trip bolt.
The profile of described collet head is the cylindrical structural being provided with annular groove.
The drift of described spring is greater than the length of described connecting rod.
The length of described connecting rod is greater than the length of described collet head.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, when dismantling bolt, nut and being fastening, when spanner reaches certain limit to bolt, nut applied force square, collet head just can skid in connecting rod, thus can effectively prevent because moment is excessive and cause bolt, nut to damage, and the size of the maximum moment of its load can be changed, so not only use cost can be reduced, and the labour intensity of workmen can be reduced, be conducive to increasing work efficiency.
