Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1-3 As shown, a screwdriver for protective special screws according to an embodiment of the present invention includes a handle 10, a shank 20, a cutting head 30, and a second actuating block 40.

[0031] The handle 10 is used for gripping and can be made of rubber or hard plastic. The handle 10 has anti-slip protrusions. One end of the blade shank 20 is connected to the handle 10. For example, the blade shank 20 and the handle 10 are connected by threaded connection, glue bonding, or other means. The blade head 30 is fixedly connected to the other end of the blade shank 20. Specifically, the blade head 30 is integrally formed with the blade shank 20, and the blade head 30 is flat. The end of the blade head 30 has an opening 31 and a first actuating block 32. The second actuating block 40 is rotatably connected to the opening 31. Rotating the second actuating block 40 causes the opening 31 to open or close.

[0032] In one embodiment of this utility model, such as Figures 1-3 As shown, the opening 31 is located at the middle position of the end of the cutter head 30, and the two sides of the opening 31 form a first actuating block 32. The second actuating block 40 is located between the two first actuating blocks 32. When the second actuating block 40 rotates to close the opening 31, the surface of the second actuating block 40 is flush with the surface of the first actuating block 32.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, corresponding through holes 50 are provided on the first actuating block 32 and the second actuating block 40, and a rotating shaft 60 is installed through the through holes 50.

[0034] In a specific embodiment of this utility model, an interference fit can be provided between the rotating shaft 60 and the first actuating block 32 and the second actuating block 40, that is, a certain force needs to be applied to the second actuating block 40 to rotate the second actuating block 40, so that the second actuating block 40 will not rotate arbitrarily.

[0035] In one embodiment of this utility model, such as Figure 2As shown, a limiting component 70 is provided between the first actuating block 32 and the second actuating block 40. The limiting component 70 includes a limiting rod 72, which is disposed on the side wall of the second actuating block 40. The side wall of the first actuating block 32 is provided with an arc-shaped limiting groove 71 corresponding to the limiting rod 72. The second actuating block 40 rotates along the arc-shaped limiting groove 71 through the limiting rod 72, so that the second actuating block 40 opens or closes the opening 31.

[0036] In one embodiment of this utility model, the arc-shaped limiting groove 71 is a quarter-circle ring.

[0037] In the embodiments of this utility model, such as Figure 3 As shown, by setting the arc-shaped limiting groove 71, the second actuating block 40 can only rotate within a 90-degree range. Figure 7 The diagram shown is a plan view of a protective special screw. In use, when it is necessary to unscrew the protective special screw, the actuating block 2 40 is rotated to close the opening 31, and the actuating block 2 40 is flush with the actuating block 1 32. Figure 1 As shown, the ends of the second actuating block 40 and the first actuating block 32 are inserted into the slot of the screw head, pressing the locking rod downwards. Then, the screwdriver is turned to push the protective special screw out of the screw hole. When installing the protective special screw, the second actuating block 40 rotates 90 degrees, so that the opening 31 is in an open state, as shown. Figure 3 As shown, it should be noted that the width of the opening 31 is greater than the diameter of the locking rod, and the length of the locking rod at the upper end of the slot is less than the length of the opening 31. After rotating the second toggle block 40, the end of the cutter head 30 is inserted into the slot, the locking rod is located in the opening 31, and then the screwdriver is rotated to drive the protective special screw into the screw hole.

[0039] like Figures 4-6 As shown, unlike Embodiment 1, in this embodiment of the present invention, the opening 31 is provided on one side of the end of the blade 30, and the other side forms a toggle block 32.

[0040] like Figure 7 As shown, during use, when it is necessary to unscrew the protective special screw, the second actuating block 40 is rotated to close the opening 31, and the second actuating block 40 is flush with the first actuating block 32, as shown in the specific state. Figure 4 As shown, the ends of the second actuating block 40 and the first actuating block 32 are inserted into the slot of the screw head, pressing the locking rod downwards. Then, the screwdriver is turned to push the protective special screw out of the screw hole. When installing the protective special screw, the second actuating block 40 rotates 90 degrees, so that the opening 31 is in an open state, as shown. Figure 6 As shown, after rotating the second toggle block 40, insert the end of the first toggle block 32 into the slot on one side of the locking rod, and then rotate the screwdriver to drive the protective special screw into the screw hole.

[0041] According to an embodiment of the present invention, a screwdriver for protective special screws comprises an opening 31 at the end of the blade tip 30 to form a first actuating block 32, and a second actuating block 40 rotatably disposed at the opening 31. By rotating the second actuating block 40, the opening 31 can be either open or closed. When closed, the first actuating block 32 and the second actuating block 40 are inserted into the slot of the protective special screw for disassembling the screw; when open, the first actuating block 32 is inserted into the slot of the protective special screw for installing the screw. The screwdriver of the present invention makes the disassembly and assembly of protective special screws more convenient.
