Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the hand tool of the present invention, and more particularly to a quick connector. [Prior Art] The quick joint refers to a structure provided for the screwdriver head. After the screwdriver head is assembled on the quick spring joint, and then the tool is driven to rotate the quick joint, the screwdriver head can be rotated at the same time to perform the work, and Replace the different size of the screwdriver head; however, in the past, when the quick connector was produced, as shown in Figures 1 and 2, a ring 20, a spring 30 and a C-shaped buckle were sequentially disposed on a body 10. After 40, a casing 50 is further disposed, and one end 51 of the casing 50 is stamped and bent to be tightly clamped to the collar 20, so that the collar 20 is interlocked with the casing 50 ® and the spring 30 is restrained. Between the collar 20 and the C-shaped buckle 40, the spring 30 can push the collar 20 to provide the restoring force of the outer casing 50 when the outer casing 50 is actuated and the displacement of the collar 20 is interlocked; As shown in FIG. 3 and FIG. 4, a quick connector is provided with a ring 20, a C-shaped buckle 40 and a spring 30 on a body 10, and then a casing 50 is disposed, and the casing 50 is disposed. One end 51 also needs to be stamped and bent to be tightly clamped to the collar 20, and the foregoing The speed joint is the same, and the 5 1325354 collar 20 is interlocked with the outer casing 50 to restrain the spring 30 between the C-shaped buckle 40 and the outer casing 50, so that the spring 30 can be actuated in the outer casing 50 and interlocked with the sleeve. When the ring 20 is displaced, the collar 20 is pushed to provide the restoring force of the outer casing 50; however, the two types of quick joints described above must also punch the end 51 of the outer casing 50 during the process to deform the end 51 and clamp the same. The collar 20 not only increases the trouble of engineering production, but also increases the difficulty of assembly, which is inconvenient. SUMMARY OF THE INVENTION It is an object of the present invention to provide a quick connector that is easy to assemble. For the above purpose, the quick connector includes a body, a C-shaped buckle and a casing, the body has a ring groove, the C-shaped buckle is disposed on the ring groove of the body, and the ring groove has a size smaller than the C The buckle has a space between the C-shaped buckle and the bottom surface of the ring groove for radially compressing the C-shaped buckle, and one end of the inner side of the outer casing forms a pushing portion corresponding to the C-shaped buckle, the pushing portion Expanding outwardly from the inner side of the outer casing, the outer casing is radially compressed by the pushing portion against the C-shaped buckle and sleeved on the body, and the C-shaped buckle is restored to limit the outer casing to the body; In the production, the outer casing can press the C-shaped buckle while being sleeved on the main body to be limited to the main body, which makes the assembly easier, saves the steps of the conventional processing, and simplifies the maintenance and lifting. Assembly speed 〇 [Embodiment] The tree quick coupling is implemented as shown in Fig. 5, and includes: - a body 60 having a cylindrical shape and an intermediate accommodation space 6; the body = end to another: end sequential molding a penetrating portion 62, a load-bearing ... - two: ': the sea tooth portion 62 and the accommodation space 61 In this embodiment, the two-transmissive portion 62 is a circular perforation that tapers from the outside toward the accommodating space 61. The fixing member 7 is placed in the penetrating portion 62 of the cymbal body 60. The position member 70 is a steel ball, and the diameter of the positioning member 70 is larger than the diameter of the tooth permeable portion 62 on the side of the accommodating space 61; a spring 80 is sleeved outside the body 6 and one end abuts against the body 6 a retaining edge 63 of the cymbal; a C-shaped buckle 90 is fastened in the annular groove 64 of the body 6〇, and the size of the annular groove 64 is smaller than the size of the C-shaped buckle 90, so that the C-shaped buckle 9〇 The bottom surface of the annular groove 64 has a space for radially compressing the c-shaped buckle 9; and the outer surface A is cylindrical, and the inner side of the outer casing a is sequentially formed from one end to the other end. a limiting surface A2, a first retaining edge VIII, and a second retaining edge A4, the pushing portion A1 corresponding to the c-shaped buckle 9 扣 buckled on the body 6〇, the pushing portion A1 is further The inner side of the outer casing A is outwardly expanded. In this embodiment, the cymbal pushing portion A1 is a slanting surface. When the outer casing A is assembled, as shown in FIG. 6, the 1325354 first pushes the abutting portion A1 toward the penetrating portion 62 of the body 60. Set up, as shown in Figure 7 It is shown that the pushing portion A1 pushes against the C-shaped buckle 90 to compress it radially, and the limiting surface A2 of the outer casing A can further restrict the C-shaped buckle 90, so that the C-shaped buckle 90 is sleeved on the outer casing A. During the process of the body 60, the C-shaped buckle 90 is restored and the first rib of the outer casing A is restored. A3, and the outer casing A is limited to the body 60, and the second rim A4 of the outer casing A also abuts against the other end of the battalion 80. It can be seen that when the quick connector is assembled, the positioning member 70, the spring 80 and the C-shaped buckle 90 are first disposed on the body 60, and then the outer casing A is directly sleeved on the body 60, and the pushing portion of the outer casing A is A1 will push against the C-shaped buckle 90 for radial compression. When the outer casing A is sleeved on the body 60, the C-shaped buckle 90 will be restored if it is lost, and the first retaining edge A3 of the outer casing A is locked. Limiting the outer casing A, and the pushing portion A1 is a sloped surface in this embodiment, and may also be a curved surface, but the actuation is similar to the operation of the inclined surface, so the details are not described herein; Not only is it easy to assemble, but it does not require additional processing, but it can actually achieve simplified engineering and save time and money. 8 1325354 [Simple description of the diagram] Figure 1 Schematic diagram of the cooperation of the components of the conventional quick connector.
