[0025] Based on the above structure, the cross mounting groove 2 is shaped such that the horizontal groove is shorter than the vertical groove, so that the glass blade can be quickly inserted into the cross mounting groove 2 for installation, so that it can be quickly positioned. The vertical groove extends to a longer distance inside the handle 1. The first positioning rod 19 and the second positioning rod 21 are both made of metal to improve their service life. The two positioning holes 22 are distributed in a straight line. The second positioning rod 21 is longer than the first positioning rod 19. The horizontal groove is consistent with the width of the stripping blade 3 to avoid shaking of the stripping blade 3 after installation.

[0026] like Figure 2 and 3 As shown, the driving unit includes two sector gears 16 rotatably connected to the inner wall of the cross mounting groove 2, the two sector gears 16 are respectively meshed with the first rack 18 and the second rack 20, one end of the two sector gears 16 is rotatably connected to the rotating rod 15, the inner wall of the cross mounting groove 2 is provided with two limit grooves 24, the inner walls of the two limit grooves 24 are slidably connected with two limit blocks 23, the opposite surfaces of the plurality of limit blocks 23 are respectively connected to the two sides of the corresponding first rack 18 and the second rack 20, by setting the limit grooves 24 and the limit blocks 23, the first rack 18 and the second rack 20 can be limited, so that they are more stable during movement.

[0027] Example 2

[0028] like Figure 4 As shown, a fixing plate 5 is installed on the inner wall of the handle 1, a threaded hole is opened on one side of the fixing plate 5, a screw rod 6 is connected to the thread in the threaded hole, one end of the screw rod 6 extends to the outside of the handle 1 and is installed with a knob 4, a connecting block 9 is installed on the end of the screw rod 6 away from the knob 4, a driving rod 10 is installed on one side of the connecting block 9, a rotating seat 14 is installed on one end of the driving rod 10, one side of the rotating seat 14 is rotatably connected to two rotating rods 15 respectively, and the thread lead angle of the screw rod 6 here is smaller than the friction angle, so that the screw rod 6 has a self-locking function.

[0029] like Figure 3 and 4 As shown, the inner wall of the slide groove 7 is slidably connected with two limit plates 8, and the opposite surfaces of the two limit plates 8 are respectively connected to the surface of the connecting block 9, and a fixing block 12 is installed on the inner wall of the handle 1, and a spring 13 is installed on one side of the fixing block 12. The spring 13 is sleeved on the surface of the driving rod 10, and a sliding block 11 is sleeved and installed on the surface of the driving rod 10. An end of the spring 13 away from the fixing block 12 is connected to one side of the sliding block 11, and an avoidance hole is opened on one side of the fixing block 12, and the avoidance hole is slidably connected with the surface of the driving rod 10. Through the set spring 13, the meshing force between the two sector gears 16 and the first rack 18 and the second rack 20 can be improved through the elastic force of the spring 13 after installation, so as to avoid shaking and cause wear between the two positioning holes 22 and the first positioning rod 19 and the second positioning rod 21.

[0030] Working principle of this utility model:

[0031] When in use, a convenient replacement component is provided. Through the provided knob 4 and screw 6, when disassembling, the knob 4 can be turned to rotate the screw 6, driving the connecting block 9 to squeeze the driving rod 10, and the driving rod 10 drives the movement of the rotating seat 14, so that the two sector gears 16 can move away from each other, and then the first rack 18 and the second rack 20 can move away from each other, so as to achieve disassembly. When installing, the reversing knob 4 drives the screw 6 to reverse, so that its driving rod 10 drives the rotating seat 14 to move toward the handle 1, and then drives the two sector gears 16 to move toward each other, thereby driving the first rack 18 and the second rack 20 to move toward each other, so that the first positioning rod 19 and the second positioning rod 21 are inserted into the two positioning holes 22 to achieve installation. This solves the problem that the common stripper handle and the stripping blade 3 are usually integrally formed, that is, the stripper usually cannot replace the stripping blade 3 separately, so when the stripping blade 3 is worn, the entire stripper is usually replaced, which increases the material cost and causes the problem of waste of resources.
