One end of the rasp 35b is also a coupling end 38 provided with external threads to be screwed into or separated from the screw hole 33 of the second end surface of the connecting holder 31. When in use, the tire repairing fork 35a or the file 35b can be assembled with the connecting seat 31 as required, as shown in fig. 5 and 8, to replace the tire repairing fork or the file.

In practice, the number of tool elements 35 can be only one, for example the repair fork 35a. Furthermore, the form of the tool element 35 is not limited to that shown in the present specification.

A first leakage-stopping element 40 and a second leakage-stopping element 45, both leakage-stopping rings in this embodiment, are disposed in the communication hole 24 of the connector 20, wherein the first leakage-stopping element 40 is located at the position of the connection end 21, as shown in fig. 4, and is disposed in a ring chamber 241 located at the connection hole 27, and the second leakage-stopping element 45 is located at the position of the inflation end 22 and is disposed in a ring groove 242 located at the inflation connection hole 28.

The receiving cylinder 50 is a hollow cylinder, and a receiving space 51 is formed inside the receiving cylinder. One end (front end) of the storage tube 50 is an open end; a combining portion 52, which is provided at the open end (front end) of the receiving cylinder 50 and has a circular hole, wherein the combining portion 52 is selectively connected to the first circumferential portion 25 or the second circumferential portion 26 of the adaptor 20 and is separable, and in the embodiment, the hole of the combining portion 52 is matched with the circular diameter of the first and second

circumferential portions

25, 26. The coupling portion 52 is provided with an internal thread such that the coupling portion 52 is screwed or separated from the first or second

circumferential portion

25, 26. The other end (rear end) of the storage cylinder 50 can be a closed end; in this embodiment, the other end (rear end) of the storage cylinder is an open end; a cover 55 is detachably connected to the other end of the cartridge, such as by screwing, snapping or the like. The cover 55 has a protrusion 56 formed at the center of the inner end surface thereof, and an annular recess 57 formed at the periphery of the protrusion 56. And a plurality of tire repairing strips 58 which are accommodated in the accommodating cylinder 50 and can be taken out from the accommodating cylinder to repair the broken hole of the tire. Referring to fig. 4, when the tire repairing strip 58 is received in the receiving tube 50, one end of the tire repairing strip 58 is inserted into the annular recess 57, so that the tire repairing strips are regularly and neatly arranged in the receiving tube in an annular form.

Fig. 1 and 4 show the tool set 10 in a stowed position when not in use, in which the receiver 50 is engaged with the adapter 20, and the engaging portion 52 of the receiver 50 is threadedly engaged with the first circumferential portion 25 of the adapter 20, such that the connecting end 21 of the adapter 20 is located in the receiving space 51 of the receiver 50; the screw portion 32 of the connecting seat 31 of the tool 30 is screwed with the connecting hole 27 of the connecting end 21 of the joint 20 and is received in the receiving space 51 of the receiving cylinder without being exposed. FIG. 4 shows a tool element (e.g., the tire puncture fork 35 a) of the tool 30 connected to the connecting end 21 of the connector 20; and the other tool member (e.g., the rasp 35 b) is received in the receiving space 51 like the prosthetic band 58.

Thus, the tool set 10 is small in size and convenient to store and carry.

When the tire repair fork 35a of the tool set 10 is used to perform tire repair, the first circumferential portion 25 of the connector 20 is separated from the connecting portion 52 of the receiving tube 50, and then, as shown in fig. 5 to 7, the second circumferential portion 26 of the connector 20 is connected to the connecting portion 52 of the receiving tube, so that the connecting end 21 and the tool 30 protrude from the front end of the receiving tube 50, and the fork portion 36 of the tire repair fork 35a clamps a tire repair strip 58, so that the tire repair strip 58 can be filled in the tire hole through the tire repair fork 35a. As can be seen from the drawings, when performing the tire repairing work, the storage tube 50 can be used as a handle of a tool set to be held by a user so as to facilitate the tire repairing work by operating the tire repairing fork 35a. The tool element 35 of the tool set 10 can be replaced by a rasp 36b instead of a tire repair fork 35a, as shown in fig. 8, to grind tires or other parts of the bicycle to be ground.

Fig. 9 and 10 show a tire valve of a standard, such as an american-style valve 60, being inflated, in use, by separating the connector 20 from the receiving tube 50 and the tool 30 from the connecting hole 27 of the connector 20, and then connecting the american-style valve 60 with the first hole portion 281 of the inflation connecting hole 28 of the inflation end 22, the second leakage-stopping element 45 in the inflation connecting hole 28 will be pressed by the valve 60, so that the air valve 60 and the inflation connecting hole 28 are kept airtight. Then, the nipple 72 of the inflation gas bottle 70 with high pressure gas is screwed into the connection hole 27 of the connection end 21, and the first leakage stopping member 40 in the connection hole 27 is pressed by the nipple 72, so that the air tightness between the nipple 72 and the connection hole 27 is maintained. The gas cylinder thimble 29 will pierce the sealing film of the gas cylinder, so that the high-pressure gas in the gas cylinder flows from the connection end 22 of the connector to the inflation end 22, and flows into the gas nozzle 60 from the communication hole 24 to inflate the tire.

After inflation, the tool set 10 can be assembled to return to the storage position shown in fig. 1 by separating the inflation bottle 70 from the connection hole 27 and separating the first hole portion 281 of the inflation connection hole 28 from the american-style air faucet 60.

Fig. 11 and 12 show another tire valve, such as a french valve 65, being inflated, when the valve is used, the valve 65 is connected to the second hole portion 282 of the inflation hole 28 of the inflation end 22, and the second leak-stopping element 45 in the inflation hole 28 is pressed by the valve 65, so that the valve 65 and the inflation hole 28 are kept airtight. Then, the nipple 72 of the inflation gas bottle 70 with high pressure gas is screwed into the connection hole 27 of the connection end 21, and the first leakage stopping member 40 in the connection hole 27 is pressed by the nipple 72, so that the air tightness between the nipple 72 and the connection hole 27 is maintained. The gas cylinder thimble 29 will pierce the sealing film of the gas cylinder, and the high-pressure gas in the gas cylinder flows into the gas nozzle 65 from the communication hole 24 to inflate the tire.

The preferred embodiment of the present invention provides a kit 10 for repairing and inflating tires. In the structural design of the present invention, the connecting end 21 of the connector 20 is connected to the tool 30 and the inflation cylinder 70, and the inflation end 22 is only used for connecting the tire valve.

Furthermore, when the tool set 10 is not used, as shown in fig. 1, the tool 30 is accommodated in the accommodating cylinder 50, so that the volume of the tool set can be saved and the tool set is convenient to carry. When used for tire repair, the storage tube 50 serves as a grip for the tool 30, as shown in fig. 5, so that the user can operate the tool set more easily and more easily.

The above-mentioned embodiments are merely to illustrate the features of the present invention, but not to limit the scope of the present invention, and all equivalent modifications of the present invention should be regarded as the protection scope of the present invention. The utility model is an original structure of similar articles and has the enhancement of efficacy, which is honest to the patent requirements.
