The movable plate 11 is placed vertically, and its bottom is set as a T-shape, which cooperates with the T-shaped through groove on the base 10 to realize the sliding of the movable plate 11 along the groove. The surface of the movable plate 11 is machined with two through holes for fixing the U-shaped clamping screw 9. One end face of the movable plate 11 is provided with a protruding groove for positioning the control stick handle and preventing the handle from rotating. The U-shaped clamping screw 9 is a slender rod with threads at both ends and bent into a U-shape. After its two ends pass through the through holes on the surface of the movable plate 11, it is fastened with a wing nut and a washer to clamp and fix the control stick handle.

[0008] Furthermore, the inner walls of the upper clamp 5 and the lower clamp 3 are fitted with rubber pads 8 to increase friction.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.

[0022] This embodiment provides a disassembly and assembly device for an aircraft control stick handle. The disassembly and assembly device includes a wrench end and a movable end, wherein the movable end is used to clamp the control stick handle, and the wrench end is used to tighten the connecting nut between the control stick handle and the stick body.

[0023] like Figure 1 As shown, the wrench end includes a Haver clamp with a handle and a lever 2; as Figure 2 , Figure 4 , Figure 5 As shown, the Haval clamp with handle is composed of a semi-circular upper clamp 5 and a lower clamp 3, which are connected by a pin 4 to form an openable structure. At the opening, the lower clamp 3 is connected to a clamping bolt 7 via the pin 4. The clamping bolt 7 passes through the upper clamp 5 and engages with the sleeve nut 6 to achieve clamping. The lower end of the lower clamp 3 is a cylindrical handle, and the force-applying rod 2 is a cylindrical long rod (e.g., Figure 3 The upper end of the upper clamp 5 has an axial blind hole for inserting the cylindrical handle of the lower clamp 3; one end of the pin 4 is machined with a shoulder, and the other end is machined with an axial blind hole. After assembly, the end with the blind hole is flanged and riveted, which is simpler and more reliable than using nuts or cotter pins for fixing; the inner walls of the upper clamp 5 and the lower clamp 3 are covered with rubber pads 8 to increase friction.

[0024] like Figure 6 As shown, the movable end includes a U-shaped clamping screw 9, a base 10, and a movable plate 11; the upper surface of the base 10 is machined with a T-shaped through groove (such as...). Figure 7 The movable plate 11 is placed vertically, as shown. Figure 8 As shown, its bottom is T-shaped, which cooperates with the T-shaped through groove on the base 10 to realize the sliding of the moving plate 11 along the groove. The moving plate 11 has two through holes machined on its surface for fixing the U-shaped clamping screw 9. One end face of the moving plate 11 has a protruding groove for positioning the control stick handle and preventing the handle from rotating. The U-shaped clamping screw 9 is a slender rod with threads machined at both ends and bent into a U-shape. After its two ends pass through the through holes on the surface of the moving plate 11, it is fastened with a wing nut and a washer to clamp and fix the control stick handle. A rubber tube is sleeved on the U-shaped clamping screw 9 to prevent the control stick handle from being pinched.

[0025] Simply apply an appropriate amount of grease to the T-shaped groove on the base of the mobile device.

[0026] Working process: During operation, clamp and fix the movable end of the base 10 to the vise. Apply an appropriate amount of grease to the T-slot of the base 10. Fix the control lever handle to the moving plate 11 using the U-shaped clamping screw 9, and place the moving plate 11 into the T-slot of the base 10. Clamp and fix the other end of the control lever handle to another vise. Open the upper clamp 5 and lower clamp 3 of the wrench end and clamp them onto the handle nut. Tighten the wrench by using the socket nut 6 and clamping bolt 7. Put the extension rod 2 on the handle of the lower clamp 3 and rotate the Haval clamp to complete the loosening and tightening of the handle nut.
