Description
Technical field
The utility model relates to a kind of spanner, specifically a kind of T-shaped can antioverloading box spanner, belong 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 cause bolt, nut to damage T-shaped can antioverloading box spanner.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of T-shaped can antioverloading box spanner, comprise handle, tapped through hole, screw rod, knob, connecting rod, circular hole, screw hole, trip bolt, slide block, spring, collet head, annular groove, it is characterized in that: the middle part of described handle is provided with tapped through hole, is provided with screw rod in tapped through hole, the upper end of screw rod is provided with knob, the lower end of screw rod is provided with slide block, one end of screw rod is fixedly connected with one end of knob, and the other end of screw rod is fixedly connected with one end of slide block, and one end of 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, is provided with trip bolt in screw hole, is provided with slide block in connecting rod, spring and collet head, collet head is provided with annular groove, one end of screw rod enters after in connecting rod through the tapped through hole be arranged in the middle part of handle and is fixedly connected with one end of slide block, collet head is entering after in connecting rod, the screw rod embedding of trip bolt is arranged in the annular groove on collet head, is fixed in connecting rod by collet head.
The length of described slide block is greater than the width of described annular groove.
The length of described connecting rod is greater than the length of described screw rod.
The length of described connecting rod is greater than the length of slide block.
The length of described connecting rod is greater than the drift of described spring.
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.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of T-shaped can antioverloading box spanner, comprise handle 1, tapped through hole 2, screw rod 3, knob 4, connecting rod 5, circular hole 6, screw hole 7, trip bolt 8, slide block 9, spring 10, collet head 11, annular groove 12, it is characterized in that: the middle part of described handle 1 is provided with tapped through hole 2, screw rod 3 is provided with in tapped through hole 2, the upper end of screw rod 3 is provided with knob 4, the lower end of screw rod 3 is provided with slide block 9, one end of screw rod 3 is fixedly connected with one end of knob 4, the other end of screw rod 3 is fixedly connected with one end of slide block 9, one end of connecting rod 5 is fixedly connected with the middle part of handle 1 is vertical, connecting rod 5 is provided with circular hole 6, the lower end of connecting rod 5 is provided with screw hole 7, is provided with trip bolt 8 in screw hole 7, is provided with slide block 9 in connecting rod 5, spring 10 and collet head 11, collet head 11 is provided with annular groove 12, one end of screw rod 3 enters after in connecting rod 5 through the tapped through hole 2 be arranged in the middle part of handle 1 and is fixedly connected with one end of slide block 9, collet head 11 is entering after in connecting rod 5, the screw rod embedding of trip bolt 8 is arranged in the annular groove 12 on collet head 11, is fixed in connecting rod 5 by collet head 11.
