Example 4:

this example is substantially the same as example 3, except that: as shown in fig. 8, a spring installation groove 102 is provided between the inner wall of the casing 1 and the upper section of the compression leg 2, and the return spring 3 is disposed in the spring installation groove 102.

Example 5:

this embodiment is substantially the same as embodiment 1 except that, as shown in fig. 10, the positioning projections 4 are configured to be retracted into the surface of the clip mounting section under external pressure, and therefore, there are provided elastic members for providing a restoring force to the positioning projections 4, the restoring force being capable of causing the positioning projections 4 to protrude outward from the surface of the clip mounting section. In this embodiment, a cavity is arranged on the clip mounting section, the elastic component is a compression spring 401, the positioning protrusion 4 is a ball 402, the compression spring 401 is arranged in the cavity, and the outer end of the compression spring 401 is in contact with or connected with the ball 402; the surface of the clamp mounting section is provided with a mounting hole communicated with the cavity, the ball 402 is arranged at the mounting hole, and the diameter of the ball 402 is slightly smaller than the aperture of the mounting hole, so that the ball 402 can protrude outwards from the surface of the clamp mounting section under the action of the reset force of the compression spring 401, and can not be extruded out of the mounting hole. The fan blade clamp 5 used in cooperation with the assembly fixture of the embodiment can have two structural forms, one is provided with the positioning hole 501, and the other is not provided with the positioning hole 501. In the latter case, the pressing force acting on the blade clamp 5 via the compression spring 401 and the ball 402 makes it fixed in position on the clamp mounting section.

When the fan blade clamp 5 is placed on the clamp mounting section, the ball 402 retracts into the mounting hole under the extrusion action of the fan blade clamp 5 and compresses the compression spring 401, and after the ball 402 is superposed with the positioning hole 501, the ball 402 is partially ejected out of the mounting hole under the action of the reset force of the compression spring 401, protrudes out of the surface of the clamp mounting section and enters the positioning hole 501, so that the fan blade clamp 5 is fixed on the clamp mounting section. When the fan blade clamp 5 is extruded out of the clamp mounting section by the sleeve 1, the ball 402 is firstly separated from the positioning hole 501 under the extrusion action of the fan blade clamp 5, retracted into the mounting hole, and compressed by the compression spring 401, when the fan blade clamp 5 moves downwards until the ball 402 is not in contact with the inner wall of the fan blade clamp 5, the inner wall of the sleeve 1 continues to extrude the ball 402, and the compression spring 401 keeps a compressed state. After the fan blade clamp 5 is installed, the assembly fixture is reset, the clamp installation section extends out of the sleeve 1, the sleeve 1 is separated from the ball 402, the extrusion force applied to the ball 402 disappears, and the ball 402 is partially ejected out of the installation hole under the action of the reset force of the compression spring 401 and protrudes out of the surface of the clamp installation section.

In a further modification of this embodiment, as shown in fig. 11, the positioning projection 4 may also employ a spherical cap 404.

Example 6:

this embodiment is substantially the same as embodiment 1 except that, as shown in fig. 12, the positioning projections 4 are configured to be retracted into the surface of the clip mounting section under external pressure, and therefore, there are provided elastic members for providing a restoring force to the positioning projections 4, the restoring force being capable of causing the positioning projections 4 to protrude outward from the surface of the clip mounting section. In this embodiment, a groove is formed on the clip mounting section along the axial direction of the compression leg, and the elastic member and the positioning protrusion 4 are designed to be an integral component, specifically, a structure of the spring plate 403. The spring plate 403 includes an elastic section and free sections disposed on two sides of the elastic section, the elastic section is in a V-shaped, U-shaped or semicircular arch structure, and the free sections are in a sheet structure. The elastic section and the free sections at two sides form an integral part which is equivalent to the elastic part, and the arch structure of the elastic section protrudes out of the surface of the clamping hoop mounting section, namely the positioning bulge 4. The spring tabs 403 are disposed in the grooves and the spring section's arcuate configuration protrudes from the clip mounting section surface. The fan blade clamp 5 used in cooperation with the assembly fixture of the embodiment can have two structural forms, one is provided with the positioning hole 501, and the other is not provided with the positioning hole 501. In the latter case, the pressing force acting on the blade clamp 5 through the arching structure of the elastic section makes the blade clamp installed and positioned on the clamp installation section.

When the device is used, when the fan blade clamp 5 is placed on the clamp mounting section, the arch structure of the elastic section deforms under the extrusion effect of the fan blade clamp 5 and shrinks towards the inside of the groove, and meanwhile, the free sections at two ends are extruded towards the axial direction of the pressing column 2, so that the transverse displacement of the arch structure is converted into the vertical displacement of the free sections, and finally, the whole arch structure shrinks into the groove, and after the arch structure is superposed with the positioning hole 501 of the fan blade clamp 5, the elastic section recovers, the arch structure protrudes out of the surface of the clamp mounting section and enters the positioning hole 501, so that the fan blade clamp 5 is fixed on the clamp mounting section. When the fan blade clamp 5 is extruded out of the clamp installation section by the sleeve 1, the arch structure is firstly separated from the positioning hole 501 under the extrusion action of the fan blade clamp 5 and retracts into the groove, and when the fan blade clamp 5 moves downwards until the outer wall of the arch structure is not contacted with the inner wall of the fan blade clamp 5, the inner wall of the sleeve 1 continues to extrude the arch structure. After the fan blade clamping hoop 5 is installed, the assembly fixture resets, the clamping hoop installation section extends out of the sleeve 1, the sleeve 1 is separated from the outer wall of the arch structure, the extrusion force applied to the outer wall of the arch structure disappears, the elastic section restores, and the arch structure protrudes out of the surface of the clamping hoop installation section.
