[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-5 As shown, this utility model provides a technical solution: a screwdriver for screen plates, including a connecting block 1, a self-opening mechanism 2 on the left side of the connecting block 1, and a convenient replacement mechanism 3 on the connecting block 1. The self-opening mechanism 2 includes a screwdriver head 21, which is fixedly connected to the left side of the connecting block 1. A wedge-shaped shovel 22 is movably connected to the top of the screwdriver head 21. A first connecting hole 23 is opened on the top of the screwdriver head 21, and a second connecting hole 24 is opened on the top of the wedge-shaped shovel 22. Through the design of the wedge-shaped shovel 22 and the groove 25, it is easy for this structure to be inserted into the screen plate. When the wedge-shaped shovel 22 is in place, the screen plate can be easily pried off by rotating the handle 31 with the screwdriver head 21 as the fulcrum. In actual use, where it used to take four people to replace the screen plate, with this structure, only two people can disassemble the screen plate, saving 1-2 hours compared to the original, reducing the labor intensity of employees, improving work efficiency, and facilitating equipment maintenance.

[0028] As one implementation method in this embodiment, such as Figure 2 As shown, a groove 25 is provided at the top of the second connecting hole 24. The depth of the groove 25 is set to 5mm and the length of the groove 25 is set to 60mm. A connecting bolt 26 is movably inserted into the inner cavity of the first connecting hole 23 and the second connecting hole 24. A connecting nut 27 located above the wedge shovel 22 is threaded onto the outer wall of the connecting bolt 26. After the connecting bolt 26 is inserted into the interior of the first connecting hole 23 and the second connecting hole 24, if the connecting nut 27 is in an untightened state, the screwdriver head 21 and the wedge shovel 22 can be rotatably connected. If the connecting nut 27 is in a tightened state, the screwdriver head 21 and the wedge shovel 22 can be fixedly connected, which facilitates the use of this structure.

[0029] As one implementation method in this embodiment, such as Figure 3 , Figure 4 , Figure 5 As shown, the convenient replacement mechanism 3 includes a handle 31. A connecting sleeve 33 is detachably connected to the outer wall of the handle 31. A silicone sleeve 34 is fixedly connected to the outer wall of the connecting sleeve 33. A hanging piece 35 is fixedly connected to the right side of the handle 31. A connecting frame 32 is fixedly installed on the left side of the handle 31. The connecting frame 32 is movably sleeved on the outer wall of the connecting block 1. Both the connecting block 1 and the connecting frame 32 have strip grooves 321. A positioning block 323 is movably inserted into the inner cavity of the strip groove 321. A collection plate 322 is fixedly installed on the top of the positioning block 323. A rotating member 324 is rotatably connected to the bottom of the positioning block 323. A limit block 325 is fixedly sleeved on the outer wall of the rotating member 324. A rubber pad 326 is fixedly connected to the top of the limit block 325. The top of the rubber pad 326 is connected to the connecting frame 32. The bottom movable connection, through the design of the silicone sleeve 34, can improve the comfort of the staff holding the handle 31. The connecting sleeve 33 is positioned on the handle 31 by bolts, and the damaged silicone sleeve 34 can be replaced as a whole. The design of the hanging piece 35 makes it easy to hang, carry or store this structure. The limiting block 325 is rotated so that the bottom of the limiting block 325 overlaps with the bottom of the positioning block 323. Then the positioning block 323 can be pulled out from the inner cavity of the strip groove 321. The damaged self-opening mechanism 2 can be replaced as a whole, or other screwdriver structures can be replaced. After the replacement is completed, the positioning block 323 is reset and inserted, and then the limiting block 325 is reset and rotated. The elasticity of the rubber pad 326 dampens and positions the rotated limiting block 325, thus completing the convenient replacement work.

[0030] Working principle: When in use, insert the wedge shovel 22 into the screen side. When the wedge shovel 22 is in place, use the screwdriver head 21 as a fulcrum and rotate the handle 31 to easily pry off the screen plate. If it is necessary to replace the damaged self-opening mechanism 2 or replace other screwdriver structures, rotate the limiting block 325 to overlap with the bottom of the positioning block 323, and then pull the positioning block 323 out of the inner cavity of the strip groove 321 and replace it. After the replacement is completed, reset and insert the positioning block 323, and then reset and rotate the limiting block 325.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
