[0021] Example

[0022] In the prior art, the cross screwdriver currently used in the market has a relatively simple structure and is prone to slipping when screwing a screw. The cutter head is also prone to wear after long-term use and cannot be replaced.

[0023] See also Figure 1-5 The utility model provides a technical solution: an anti-slip cross screwdriver, comprising a connecting plate 1, a fixing rod 2 is fixedly arranged on one side of the connecting plate 1, one end of the fixing rod 2 is connected to a connecting seat 3, an anti-slip blade head 4 is fixedly arranged on one side of the connecting seat 3, and the outer side of the anti-slip blade head 4 is processed with anti-slip patterns, a plug-in block 5 is arranged on the other side of the connecting seat 3, and the plug-in block 5 is embedded in the interior of the fixing rod 2, a C-shaped buckle 6 is buckled on the outer side of the fixing rod 2, a pin rod 7 is arranged inside the C-shaped buckle 6, and the pin rod 7 passes through the fixing rod 2 and A plug-in block 5 and a handle 8 are provided on one side of the connecting plate 1, and a limiting structure is provided on one end of the handle 8. When in use, the anti-slip cutter head 4 is installed on one end of the fixed rod 2 through the connecting seat 3 and the plug-in block 5, and the C-shaped buckle 6 is buckled on the outside of the fixed rod 2. The pin rod 7 inside the C-shaped buckle 6 will penetrate the fixed rod 2 and the plug-in block 5 to further limit the anti-slip cutter head 4, making it convenient to disassemble and assemble the anti-slip cutter head 4. At the same time, the anti-slip cutter head 4 is processed with anti-slip patterns on the outside to avoid slipping when the screws are turned.

[0024] The limiting structure includes a baffle 9, which is installed at one end of the handle 8. A ring plate 10 is fixedly provided on one side of the baffle 9 and the ring plate 10 is connected to the inside of the handle 8. A connecting block 11 is fixedly provided on one side of the baffle 9 and the connecting block 11 is located inside the ring plate 10. A pressure plate 13 is sleeved on the outer side of the connecting block 11. A pressure plate 13 is provided at one end of the pressure plate 13 and the pressure plate 13 is slidably installed inside the handle 8. When in use, the spare anti-slip blade head 4 is placed inside the handle 8, and then the baffle 9 is installed on one end of the handle 8 through the ring plate 10. One end of the baffle 9 is connected to the pressure plate 13 through a spring 12. The pressure plate 13 will squeeze and limit the anti-slip blade head 4 inside the handle 8 to prevent the anti-slip blade head 4 from sliding and wearing inside the handle 8.

[0025] A polygonal groove is formed at one end of the fixing rod 2, and the plug-in block 5 is embedded in the polygonal groove. The plug-in block 5 limits the connection seat 3 to prevent the connection seat 3 from rotating.

[0026] The fixing rod 2 and the plug-in block 5 are both provided with pin holes, and the size of the pin rod 7 is adapted to the pin hole. The fixing rod 2 and the plug-in block 5 are limited by the pin rod 7, so that the anti-slip blade head 4 can be easily disassembled and assembled.

[0027] A storage cavity is provided inside the handle 8 , and a pressing plate 13 is slidably installed in the storage cavity. The pressing plate 13 limits the position of the anti-slip blade head 4 inside the handle 8 .

[0028] The outer side of the annular plate 10 is processed with an external thread, the inner wall of the handle 8 is processed with an internal thread, the annular plate 10 is threadedly connected to the handle 8, and the baffle 9 is installed at one end of the handle 8 through the annular plate 10.

[0029] The working principle or structural principle is that when in use, the spare anti-skid blade head 4 is placed inside the handle 8, and then the baffle 9 is installed on one end of the handle 8 through the annular plate 10. One end of the baffle 9 is connected to a pressure plate 13 through a spring 12. The pressure plate 13 will squeeze and limit the anti-skid blade head 4 inside the handle 8 to prevent the anti-skid blade head 4 from sliding and wearing inside the handle 8. Then the plug-in block 5 is inserted into one end of the fixed rod 2, and then the C-shaped buckle 6 is buckled on the outside of the fixed rod 2. The pin rod 7 inside the C-shaped buckle 6 will penetrate the fixed rod 2 and the plug-in block 5, thereby limiting the connecting seat 3 and the anti-skid blade head 4 at the end of the plug-in block 5, making it convenient to disassemble and assemble the anti-skid blade head 4. At the same time, the outer side of the anti-skid blade head 4 is processed with protective patterns to avoid slipping when the screw is turned. When the anti-skid blade head 4 needs to be replaced, the baffle 9 is rotated to separate the baffle 9 from the handle 8, thereby taking out the spare anti-skid blade head 4 inside the handle 8 for replacement.
