Description
Technical field
The utility model relates to a kind of screwdriver, and specifically a kind of antioverloading multi-purpose screw driver, 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 the antioverloading multi-purpose screw driver that can effectively prevent moment excessive and cause screw to damage.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of antioverloading multi-purpose screw driver, comprise handle, connecting rod, circular hole, screw hole, trip bolt, spring, slide block, annular groove, driver bit, latch, pin hole, connection holes, 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 slide block is provided with in circular hole, annular groove on slide block, trip bolt embeds after through the screw hole being arranged on connecting rod lower end in the annular groove that is arranged on slide block, the top of driver bit is fixedly connected with one end of slide block, slide block is provided with pin hole, latch is provided with in pin hole, connecting rod is provided with connection holes, latch is successively through the connection holes be arranged on connecting rod and the pin hole be arranged on slide block, by slider locks 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 driver bit.
The width of described annular groove is greater than the diameter of the screw rod of described trip bolt.
The profile of described handle, connecting rod is cylindrical structural.
Described trip bolt embeds after through the screw hole being arranged on connecting rod lower end in the annular groove that is arranged on slide block, and effect is fixed in circular hole by slide block.
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 driver bit.
After in described spring enters and is arranged on connecting rod circular hole, slide block also enters in the circular hole that is arranged on connecting rod, and trip bolt embeds after through the screw hole being arranged on connecting rod lower end in the annular groove that is arranged on slide block simultaneously, is fixed in connecting rod by 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, so not only can reduce use cost, 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 depicted in figs. 1 and 2, a kind of antioverloading multi-purpose screw driver, comprise handle 1, connecting rod 2, circular hole 3, screw hole 4, trip bolt 5, spring 6, slide block 7, annular groove 8, driver bit 9, latch 10, pin hole 11, connection holes 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, connecting rod 2 is provided with circular hole 3, the lower end of connecting rod 2 is provided with screw hole 4, trip bolt 5 is provided with in screw hole 4, spring 6 and slide block 7 is provided with in circular hole 3, annular groove 8 on slide block 7, trip bolt 5 embeds after through the screw hole 4 being arranged on connecting rod 2 lower end in the annular groove 8 that is arranged on slide block 7, the top of driver bit 9 is fixedly connected with one end of slide block 7, slide block 7 is provided with pin hole 11, latch 10 is provided with in pin hole 11, connecting rod 2 is provided with connection holes 12, latch 10 is successively through the connection holes 12 be arranged on connecting rod 2 and the pin hole 11 be arranged on slide block 7, slide block 7 is locked in connecting rod 2.
The length of described latch 10 is greater than the degree of depth of described pin hole 11.
The drift of described spring 6 is greater than the length of described driver bit 9.
The width of described annular groove 8 is greater than the diameter of the screw rod of described trip bolt 5.
The profile of described handle 1, connecting rod 2 is cylindrical structural.
Described trip bolt 5 embeds after through the screw hole 4 being arranged on connecting rod 2 lower end in the annular groove 8 that is arranged on slide block 7, and effect is fixed in circular hole 3 by slide block 7.
The drift of described spring 6 is greater than the length of described connecting rod 2.
