[0024] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] A sleeve ejecting device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] For easier understanding, see Figures 1 to 5 The utility model provides an embodiment of a sleeve ejection device, comprising a sleeve sleeve 1 and a sleeve needle 4, wherein a sleeve seat 2 and a fixing cover 3 are respectively arranged at both ends of the sleeve sleeve 1, and a quick-release sliding component and a heat dissipation component are arranged between the sleeve sleeve 1 and the sleeve needle 4;

[0028] The quick-release sliding assembly includes an inner seat 6, a fixed outer ring 7 and a ball 8. The inner seat 6 is respectively fixedly connected to the inner sides of the two ends of the sleeve sleeve 1, the fixed outer ring 7 is respectively fixedly installed on the inner sides of the two ends of the sleeve sleeve 1, the ball 8 is rotatably connected to the inner side of the fixed outer ring 7, one end of the fixed outer ring 7 is abutted against one end of the inner seat 6, the outer diameter of the fixed outer ring 7 matches the inner diameter of the sleeve sleeve 1, the sleeve seat 2 is threadedly engaged with one end of the sleeve sleeve 1, the inner wall of one end of the sleeve seat 2 is abutted against one end of the fixed outer ring 7, one end of the fixed cover 3 is threadedly engaged with one end of the sleeve sleeve 1, the inner wall of one end of the fixed cover 3 is abutted against one end of the fixed outer ring 7, the balls 8 are arranged in a circular array on the inner side of the fixed outer ring 7, and the outer wall of the balls 8 is abutted against the outer wall of the sleeve needle 4.

[0029] It should be noted that the inner seat 6 is provided to support the fixed outer ring 7. A separate fixed outer ring 7 is provided, and a ball 8 for supporting the sliding of the sleeve needle 4 is installed in the fixed outer ring 7. When the ball 8 in the sleeve ejection device is worn, the fixed cover 3 and the sleeve seat 2 can be rotated to separate it from the sleeve sleeve 1, and then the fixed outer ring 7 with the ball 8 is taken out from the inside of the sleeve sleeve 1, and then the new fixed outer ring 7 with the ball 8 is replaced, and the fixed cover 3 and the sleeve seat 2 are connected and fixed to the sleeve sleeve 1, so as to facilitate the quick replacement of the ball 8 and the easy use. The fixed outer ring 7 can adopt a split splicing design, which is composed of two semi-circular rings to form a whole ring, so as to make it more convenient to remove it from the sleeve sleeve 1.

[0030] Example 2

[0031] In some embodiments, Figure 1 , Figure 3 As shown, the heat dissipation component includes a first air hole 9, a second air hole 10 and a plunger 11. The first air hole 9 and the second air hole 10 are respectively opened at both ends of the sleeve sleeve 1. The plunger 11 is fixedly installed on the outer wall of the sleeve needle 4. The first air hole 9 and the second air hole 10 are respectively arranged in a circular array at both ends of the sleeve sleeve 1.

[0032] It should be noted that, by providing the first air hole 9, the second air hole 10 and the plunger 11, the first air hole 9 and the second air hole 10 are utilized to inhale or exhaust air while the sleeve needle 4 moves back and forth, so that the air flow flows in the sleeve sleeve 1, and the sleeve needle 4 and the sleeve sleeve 1 are cooled, thereby ensuring the operating stability of the sleeve ejection device.

[0033] Working principle: When in use, the ball 8 on the inner wall of the fixed outer ring 7 is used to support the sleeve needle 4 on the inner wall of the sleeve sleeve 1, and the sleeve needle 4 is assisted to move back and forth in the sleeve sleeve 1 to reduce the friction between the sleeve sleeve 1 and the sleeve needle 4. At the same time, the first air hole 9 and the second air hole 10 are used to inhale or exhaust air while the sleeve needle 4 moves back and forth, so that the air flow flows in the sleeve sleeve 1 to cool the sleeve needle 4 and the sleeve sleeve 1, thereby ensuring the operating stability of the sleeve ejection device. When the ball 8 is worn, the fixed cover 3 and the sleeve seat 2 can be rotated to separate it from the sleeve sleeve 1, and then the fixed outer ring 7 with the ball 8 is taken out from the inside of the sleeve sleeve 1, and then the new fixed outer ring 7 with the ball 8 is replaced, and the fixed cover 3 and the sleeve seat 2 are connected and fixed to the sleeve sleeve 1, so as to facilitate the quick replacement of the ball 8 and convenient use.
