Description
Technical field
The utility model relates to a kind of screwdriver, and specifically one can the T-shaped screwdriver of antioverloading, belongs 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 can the T-shaped screwdriver of antioverloading.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: one can the T-shaped screwdriver of antioverloading, comprises handle, tapped through hole, screw rod, knob, connecting rod, circular hole, screw hole, trip bolt, slide block, spring, base, annular groove, driver bit, 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 base, base 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, base is entering after in connecting rod, the screw rod embedding of trip bolt is arranged in the annular groove on base, be fixed on by base in connecting rod, one end of base is fixedly connected with the top of driver bit.
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 driver bit.
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.

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, shown in Fig. 3 and Fig. 4, one can the T-shaped screwdriver of antioverloading, comprises 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, base 11, annular groove 12, driver bit 13, 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 base 11, base 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, base 11 is entering after in connecting rod 5, the screw rod of trip bolt 8 embeds in setting annular groove 12 on the pedestal 11, be fixed on by base 11 in connecting rod 5, one end of base 11 is fixedly connected with the top of driver bit 13.
The length of described slide block 9 is greater than the width of described annular groove 12.
The length of described connecting rod 5 is greater than the length of described screw rod 3.
