[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0030] See also Figure 1-Figure 5 , this embodiment provides a detachable screwdriver, comprising: a first shank 1 and a disassembly mechanism 2;
[0031] Firstly, in order for the staff to be able to drive the first blade 1 to tighten the screw head through the hollow shell 11 after holding the handle 10; in addition, when a smaller first blade 1 is needed to tighten a smaller screw head, the two insert blocks 25 can be driven closer to each other by simultaneously pinching the two movable plates 24, so that after the insert block 25 is removed from the slot 13, the hollow shell 11 can be removed from the handle 10, and then the staff can hold the handle 10 and use the second blade 21 to tighten the smaller screw head; one end of the first blade 1 is fixedly connected to the hollow shell 11, and the hollow shell 11 is symmetrically opened There is a slot 13, and a handle 10 is provided on one side of the hollow shell 11; the disassembly and assembly mechanism 2 includes a connecting block 20 fixedly connected to one end of the handle 10, and a second knife rod 21 is fixedly connected to one side of the connecting block 20. The second knife rod 21 is inserted into the interior of the hollow shell 11, and a rod body 22 is symmetrically fixedly connected to the outside of the connecting block 20. A movable plate 24 is movably sleeved on the rod body 22, and a spring 23 is sleeved on the rod body 22. The two ends of the spring 23 are respectively fixedly connected to the connecting block 20 and the movable plate 24. One side of the movable plate 24 is inserted into the interior of the hollow shell 11 and fixedly connected to an insert block 25. One side of the insert block 25 is inserted into the interior of the slot 13;
[0032] Secondly, in order to improve the stability of the movable plate 24 when it moves, the movable plate 24 is slidably connected to a fixed rod 28 inside, and one end of the fixed rod 28 is fixedly connected to the connecting block 20; in order to prevent the movable plate 24 from detaching from the fixed rod 28, the end of the fixed rod 28 away from the connecting block 20 is fixedly connected to a stopper 29; in order to make it easier for the staff to pinch the two movable plates 24, one side of the movable plate 24 is fixedly connected to a connecting plate 26, and one side of the connecting plate 26 is fixedly connected to a protrusion 27; in order to improve the use of the protrusion In order to improve the comfort of the block 27, a rubber pad is fixedly connected to the side of the block 27 away from the connecting plate 26; in order to facilitate the first knife bar 1 and the second knife bar 21 to be inserted into the slots of corresponding sizes to screw the screw heads, a knife head 12 is provided on the end of the first knife bar 1 and the second knife bar 21 away from the handle 10; in order to facilitate the limiting of the movable plate 24 entering the interior of the hollow shell 11, so as to facilitate the position of the insert block 25 to correspond to the slot 13, a baffle 14 for limiting the movable plate 24 is fixedly connected to the inner wall of the hollow shell 11.
[0033] Working principle: When in use, under normal circumstances, the staff can hold the handle 10 and drive the first blade 1 to screw the screw head through the hollow shell 11; when it is necessary to use a smaller first blade 1 to screw a smaller screw head, the two movable plates 24 can be driven to move closer to each other by pinching the two protrusions 27 at the same time, so that the insert 25 is moved out of the slot 13 under the drive of the movable plate 24, and the hollow shell 11 can be removed from the handle 10, so that the staff can hold the handle 10 and use the second blade 21 to screw a smaller screw head. When the handle 10 needs to be installed on the hollow shell 11, the connecting block 20 and the second knife rod 21 can be inserted into the inside of the hollow shell 11 after pinching the two movable plates 24. When the movable plate 24 drives the insert block 25 to move to the position corresponding to the slot 13, the two movable plates 24 can be moved away from each other under the tensioning force of the spring 23 by loosening the movable plate 24, and then the insert block 25 can be inserted into the slot 13 under the drive of the movable plate 24, thereby completing the fixed installation of the handle 10 and the hollow shell 11.
[0034] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
