Description

One is T-shaped can antioverloading formula screwdriver
Technical field
The utility model relates to a kind of screwdriver, specifically a kind of T-shaped can antioverloading formula screwdriver, belong to machine tool technical field.
Background technology
Often need to use screwdriver to carry out dismounting and fastening to screw in machine work.At present in the polygonal structure of producing and in life, the groove of widely used screw is mostly rule, because workmen carries out dismantling and being difficult to control moment exactly in fastening process to screw at use screwdriver, often easily exceed the maximum moment that screw can carry, the groove of screw head is caused to damage, cause screwdriver to skid, bring unnecessary trouble to machine work.
Although can measure exactly at the digital force moment screw cutter produced and use in life at present and read the moment that screw carries, due to the expensive and poor reliability of digital force moment screw cutter, cannot use in machine work on a large scale.Therefore can effectively prevent moment excessive and the screwdriver causing screw to damage in the urgent need to a kind of.
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 screw to damage T-shaped can antioverloading formula screwdriver.
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 screwdriver, comprise handle, connecting rod, guide rail, circular hole, screw hole, trip bolt, studs, adjusting nut, slide block, spring, base, annular groove, driver bit, 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 base, base is provided with annular groove, when base enters in connecting rod, the screw rod embedding of trip bolt is arranged in the annular groove on base, base is fixed in connecting rod, one end of base is fixedly connected with the top of driver bit.
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 base.
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 carrying out dismounting to screw and being fastening, when screwdriver reaches certain limit to screw applied force square, driver bit just can skid, thus can effectively prevent because moment is excessive and cause screw 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.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is stereochemical structure decomposing schematic representation of the present utility model.
Fig. 3 is the perspective view of connecting rod 2 in the utility model.
In figure: 1-handle, 2-connecting rod, 3-guide rail, 4-circular hole, 5-screw hole, 6-trip bolt, 7-studs, 8-adjusting nut, 9-slide block, 10-spring, 11-base, 12-annular groove, 13-driver bit.
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, shown in Fig. 2 and Fig. 3, a kind of T-shaped can antioverloading formula screwdriver, 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, base 11, annular groove 12, driver bit 13, 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 base 11, base 11 is provided with annular groove 12, when base 11 enters in connecting rod 2, the screw rod of trip bolt 6 embeds in setting annular groove 12 on the pedestal 11, base 11 is fixed in connecting rod 2, one end of base 11 is fixedly connected with the top of driver bit 13.
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.
The length of described connecting rod 2 is greater than the height of described base 11.
The length of described studs 7 is greater than the width of described connecting rod 2.
The diameter of described circular hole 4 is greater than the diameter of described slide block 9.
When needs carry out dismounting to screw and are fastening, being aimed at by driver bit 13 and embedding needs to be disassembled with in the groove of fastening screw, then turning handle 1 can carry out dismounting and fastening to screw, when moment is greater than the frictional force at the top of spring 10 pairs of bases 11, base 11 just can skid in the connecting rod 2 being provided with circular hole 4, now increase moment in any case and all can not carry out dismounting and fastening to screw again, thus can effectively prevent because moment is excessive and cause screw to damage.
When need to regulate its can the size of maximum moment of load time, first unscrew adjusting nut 8, then change studs 7 position on guides 3, finally screw adjusting nut 8 just can change spring 10 by the degree compressed can change its can the size of maximum moment of load.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
