Two mounting plates are fixedly connected to the upper ends of the four support rods. Several fixing plates are fixedly connected to the lower ends between the two mounting plates. Each fixing plate has a first threaded hole in its middle. Adjusting screws are threaded into the interior of each of the first threaded holes. A bearing plate is rotatably connected to the upper end of each adjusting screw via a bearing. Several guide grooves are formed on opposite sides of the two mounting plates. L-shaped guide rods adapted to the guide grooves are fixedly connected to both sides of the bearing plates. Movable components are fixedly connected to both sides of the front and back of the base.

[0007] As a further improvement of this utility model, the movable component includes a storage box fixedly connected to the front and back sides of the base. The lower end of the storage box is provided with a storage groove, and the upper end of the storage box is provided with a second threaded hole. A positioning screw is threadedly connected inside the second threaded hole, and the lower end of the positioning screw is rotatably connected to a lifting block adapted to the storage groove through a bearing.

[0008] As a further improvement of this utility model, the lower end of the lifting block is fixedly connected with a caster wheel.

[0009] As a further improvement of this utility model, a knob is fixedly connected to the upper end of the positioning screw.

[0010] As a further improvement of this utility model, handles are fixedly connected to the lower ends of several of the adjusting screws.

[0011] As a further improvement of this utility model, rubber pads are provided at the upper ends of several of the bearing plates.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a support plate, during use, rotating the adjusting screw and cooperating with the guide groove on the mounting plate and the L-shaped guide rods on both sides of the support plate allows the support plate to move smoothly up and down. According to the actual shape and size of the helicopter main rotor blade, the height of each support plate can be flexibly adjusted to ensure that the rotor blade can be placed stably and fit snugly on the tooling, improving the adaptability of the tooling and meeting the placement requirements of rotor blades of different specifications.

[0014] By setting up a movable component, during use, the knob at the upper end of the positioning screw can be turned to control the lifting block to extend or retract the casters into the storage slot.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3A portable helicopter main rotor blade placement fixture includes a base 1. Support rods 2 are fixedly connected to the four corners of the upper surface of the base 1. Two mounting plates 3 are fixedly connected to the upper ends of the four support rods 2. Several fixing plates 4 are fixedly connected to the lower ends between the two mounting plates 3. The middle ends of the fixing plates 4 are provided with first threaded holes. Adjusting screws 5 are threaded into the interior of the first threaded holes. The upper ends of the adjusting screws 5 are rotatably connected to the bearing plates 6 through bearings. Several guide grooves 7 are provided on the opposite side of the two mounting plates 3. L-shaped guide rods 8 that are adapted to the guide grooves 7 are fixedly connected to both sides of the bearing plates 6. Moving components are fixedly connected to both sides of the front and back of the base 1.

[0021] In this utility model, the movable component includes a storage box 9 fixedly connected to the front and back sides of the base 1. The lower end of the storage box 9 has a storage groove. When the tooling does not need to be moved, the casters 12 can be completely stored in the storage groove, so that the base 1 directly contacts the ground, enhancing the stability of the tooling. The upper end of the storage box 9 has a second threaded hole, and the internal thread of the second threaded hole is connected to a positioning screw 10. The positioning screw 10 is made of high-strength alloy steel, which has sufficient strength and hardness and can withstand greater pressure, ensuring that it will not deform or break when adjusting the lifting block 11. The lower end of the positioning screw 10 is rotatably connected to the lifting block 11, which is adapted to the storage groove, through a bearing. The lower end of the lifting block 11 is fixedly connected to the casters 12. The casters 12 have good flexibility and steering performance, which facilitates the movement of the tooling in all directions and improves the mobility of the tooling.

[0022] A knob 13 is fixedly connected to the upper end of the positioning screw 10. The surface of the knob 13 is designed with anti-slip texture, which increases the friction between the operator's hand and the knob 13, making it easier to turn the knob 13. A handle 14 is fixedly connected to the lower end of several adjusting screws 5. By holding the handle 14 and applying torque, the adjusting screw 5 can be turned to adjust the height of the support plate 6. Rubber pads 15 are provided on the upper end of several support plates 6. The rubber pads 15 are made of rubber material and have good elasticity and flexibility. When the helicopter main rotor blade is placed on the support plate 6, the rubber pads 15 can play a role in buffering and shock absorption, effectively reducing the friction and collision between the rotor blade and the support plate 6, and protecting the rotor blade surface from damage.

[0023] In use, the tooling is first placed in a suitable position. By rotating the knob 13 at the upper end of the positioning screw 10, the positioning screw 10 rotates in the second threaded hole at the upper end of the storage box 9, driving the lifting block 11, which is connected to it via a bearing, to move downward in the storage groove. This causes the universal wheel 12, fixed to the lower end of the lifting block 11, to extend out of the storage groove. After pushing the tooling to the target location, the knob 13 is rotated in the opposite direction to retract the universal wheel 12 into the storage groove, achieving stable placement of the tooling. Then, according to the helicopter main rotor blade... The shape is adjusted by rotating the handle 14 at the lower end of the adjusting screw 5. The adjusting screw 5 rotates in the first threaded hole at the middle end of the fixed plate 4. Since the upper end of the adjusting screw 5 is rotatably connected to the bearing plate 6 through the bearing, and the L-shaped guide rods 8 on both sides of the bearing plate 6 are adapted to the guide grooves 7 opened on the opposite side of the mounting plate 3, the bearing plate 6 rises or falls smoothly under the guidance of the guide grooves 7 and the L-shaped guide rods 8. Several bearing plates 6 are adjusted to adapt to the shape of the blade, and the blade is placed on the upper end of several bearing plates 6 for inspection and maintenance.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
