[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0026] Referring to Figure 1 - Figure 2 As shown, the present utility model provides a moving fit assembly tool, which includes a bushing 1. A plurality of clamping rods 6 are slidably arranged in the bushing 1, and the plurality of clamping rods 6 are equidistantly and circumferentially distributed on the bushing 1. The clamping rods 6 are arranged along the radial direction of the bushing 1, and one end of the clamping rod 6 penetrates into the bushing 1. The clamping rod 6 is adapted to the clamping groove of the moving fit.

[0027] A moving assembly 7 is arranged on the bushing 1 for simultaneously moving a plurality of clamping rods 6.

[0028] A handle 2 is fixedly arranged on the bushing 1.

[0029] As an optional implementation manner, a quick rotation assembly 3 is arranged on the bushing 1 for quickly rotating the bushing 1.

[0030] The quick rotation assembly 3 includes a fixed sleeve 4 and a vertical rod 5. The fixed sleeve 14 is rotatably arranged on the surface of the bushing 1, and the vertical rod 5 is vertically rotatably arranged on the handle 2;

[0031] By supporting the fixed sleeve 4 and then rotating the handle 2 through the vertical rod 5, the bushing 1 can be quickly rotated. The bushing 1 can be rotated with a large torque through the handle 2, and the moving fit can be tightened through the handle 2.

[0032] The moving assembly 7 includes a rotating sleeve 10. The rotating sleeve 10 is threadedly connected to the surface of the bushing 1. An annular frustum 12 is sleeved on the surface of the rotating sleeve 10. A fixing plate 8 is fixed to the end of the clamping rod 6 away from the bushing 1, and the upper side of the fixing plate 8 corresponds to the inclined surface of the annular frustum 12. A spring 9 is sleeved on the surface of the clamping rod 6, and both ends of the spring 9 are fixed to the fixing plate 8 and the bushing 1 respectively;

[0033] By rotating the rotating sleeve 10, the rotating sleeve 10 drives the annular frustum 12 to move along the length direction of the bushing 1. By pushing the fixing plate 8 through the annular frustum 12, the fixing plate 8 drives the clamping rod 6 to move, shortening the length of the clamping rod 6 inserted into the bushing 1. When the annular frustum 12 is far away from the bushing 1, the clamping rod 6 will extend into the bushing 1 under the pulling of the spring 9, so as to be able to adjust the length of the clamping rod 6 extending into the bushing 1.

[0034] The upper side of the fixing plate 8 is designed as an inclined surface, and the inclined surface of the fixing plate 8 is parallel to the inclined surface of the annular frustum 12. Such a design can make the annular frustum 12 push the fixing plate 8 more smoothly and make the fixing plate 8 away from the bushing 1.

[0035] A number of fixing blocks 11 are provided on the surface of the rotating sleeve 10. By providing the fixing blocks 11, the friction between the rotating sleeve 10 and the hand is increased, facilitating the rotation of the rotating sleeve 10.

[0036] A waist-shaped boss 13 is provided inside the bushing 1. The waist-shaped boss 13 is in clearance fit with the waist-shaped groove on the moving mating surface, making the rotation of the bushing 1 more stable.

[0037] The handle 2 is horizontally arranged on the bushing 1, and the handle 2 is equally distributed on both sides of the bushing 1 with the bushing 1 as the center. This design facilitates the user to hold the handle 2 with both hands and is beneficial for the user to exert force.

[0038] With the above structure, the bushing 1 is inserted into the moving mating surface, the clamping rod 6 is inserted into the clamping groove of the moving mating, the inner wall of the bushing 1 is in clearance fit with the moving mating surface, and the bushing 1 is rotated through the handle 2. The bushing 1 can rotate the moving mating through the clamping rod 6;

[0039] The diameters and the depths of the clamping grooves of different specifications of the moving mating are different. By moving the moving component 7 to move the clamping rod 6, the length of the part of the clamping rod 6 inside the bushing 1 is adjusted to ensure that the clamping rod 6 can be inserted into the clamping groove of the moving mating, realizing the adaptation to different specifications of the moving mating.

[0040] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
