Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.Attached drawing is simplified schematic diagram, only to show
Meaning mode illustrates the utility model basic structure, therefore it only shows composition related with the utility model.
Embodiment one, as shown in Figure 1, the utility model are similar to engine crank structure, including sleeve 1, and 1 set of sleeve exists
The handle portion of screwdriver is mutually coincide, and the right end of sleeve 1 is plugged with L-type telescopic rod 2, and the left end of L-type telescopic rod 2 is cuboid,
It can be inserted into the card slot of 1 tail end of sleeve, L-type telescopic rod 2 is equipped with the lock screw 3 that L-type telescopic rod 2 can be locked, L-type
2 upper end of telescopic rod is hinged with operation handle 4, and operation handle 4 is equipped with gear screw 5, gear screw 5 and 2 screw thread of L-type telescopic rod
Cooperation, is equipped with the opening 6 rotate for operation handle 4 on the right side of L-type telescopic rod 2, operation handle 4 at horizontal position be open 6
Bottom end contact, when operation handle 4 goes to vertical with L-type telescopic rod 2, screws gear screw 5, so in operation, operation handle 4
Would not turn, as shown in Figure 1,3, due to operation handle 4 at horizontal position with opening 6 bottom ends contact, that is, with L
The outer wall of type telescopic rod 2 contacts, and be rotated by 90 ° operation handle 4 can only.When screw is not easy to turn, L-type telescopic rod 2 can be passed through
The arm of force, torque are increased, in addition operation handle 4 vertical direction can be folded into and further increase the arm of force, torque, become L from zigzag
At this moment type exerts a force, after screw loosening in operation handle 4, screws gear after operation handle 4 being folded into horizontal position again
Silk 5 is locked, quickly removes screw convenient for operating.
In addition, can be equipped with cuboid card slot in screw driver handle portion, L-type telescopic rod 2 can be inserted directly into cuboid card slot
It cooperates.
As shown in Figure 2, wherein L-type telescopic rod 2 include fixed link 201 and can in fixed link 201 vertical sliding L type
Bar 202, lock screw 3 is in fixed link 201.
Wherein, sliding slot 7 is equipped in fixed link 201, l-shaped rod 202 is in sliding slot 7.
Embodiment two, on the basis of example 1 is cased in operation handle 4 as shown in Figure 4 and rotatable rolls handle
8, it rolls 4 right end of handle operation handle and is fixedly connected with anticreep block 9, roll handle 8 and be equipped with non-slip rubber set.
