Description
Technical field
The utility model relates to a kind of spanner, specifically a kind of T-shaped can antioverloading formula 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 formula 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 formula spanner, comprise handle, connecting rod, guide rail, circular hole, screw hole, trip bolt, studs, adjusting nut, slide block, spring, collet head, annular groove, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the both sides of connecting rod are provided with guide rail, 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, screw hole is arranged on the below of guide rail, guide rail is provided with studs, the two ends of studs are provided with adjusting nut, slide block is provided with in connecting rod, spring and collet head, collet head is provided with annular groove, when collet head enters in connecting rod, the screw rod embedding of trip bolt is arranged in the annular groove on collet head, collet head is fixed in connecting rod.
The length of described studs is greater than the diameter of described circular hole.
The length of described connecting rod is greater than the length of described guide rail.
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 slide block.
The length of described connecting rod is greater than the height of described collet head.
The length of described studs is greater than the width of described connecting rod.
The diameter of described circular hole is greater than the diameter of described slide block.
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 formula spanner, comprise handle 1, connecting rod 2, guide rail 3, circular hole 4, screw hole 5, trip bolt 6, studs 7, adjusting nut 8, slide block 9, spring 10, collet head 11, annular groove 12, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, the both sides of connecting rod 2 are provided with guide rail 3, connecting rod 2 is provided with circular hole 4, the lower end of connecting rod 2 is provided with screw hole 5, trip bolt 6 is provided with in screw hole 5, screw hole 5 is arranged on the below of guide rail 3, guide rail 3 is provided with studs 7, the two ends of studs 7 are provided with adjusting nut 8, slide block 9 is provided with in connecting rod 2, spring 10 and collet head 11, collet head 11 is provided with annular groove 12, when collet head 11 enters in connecting rod 2, the screw rod embedding of trip bolt 6 is arranged in the annular groove 12 on collet head 11, collet head 11 is fixed in connecting rod 2.
The length of described studs 7 is greater than the diameter of described circular hole 4.
The length of described connecting rod 2 is greater than the length of described guide rail 3.
The length of described connecting rod 2 is greater than the drift of described spring 10.
The length of described connecting rod 2 is greater than the length of described slide block 9.
