[0030] The following are only examples to illustrate possible implementations of the present invention, but are not intended to limit the scope of the present invention. The "one" or "at least one" preceding the nouns mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of the protection, which is stated in advance.

[0031] Please refer to Figures 1 to 5 , which shows an embodiment of the present invention. The ceiling nail driver of the present invention includes: a main tube 1, a guide tube 2, a movable sleeve 3, a launch tube 4, a firing pin assembly 5, a driving assembly 6, a first elastic member 71, a second elastic member 72 and a third elastic member 73.

[0032] The main cylinder 1 includes a tube body 11 and a convex wall portion 12, wherein the convex wall portion 12 radially protrudes from the inner wall of the tube body 11, and the convex wall portion 12 divides the interior of the tube body 11 into a first chamber 13 and a second chamber 14 that are connected to each other; wherein the main cylinder 1 can be integrally formed by a lathe, which has the advantages of rapid production and cost saving, so as to enhance the product sales competitiveness.

[0033] The guide tube 2 is passed through the convex wall portion 12 and positioned on the tube body 11 to form a coaxial inner and outer tube structure. In more detail, the ceiling nailer further includes at least one positioning member 16, and the main tube 1 further includes at least one positioning hole 15. The at least one positioning hole 15 passes through the tube body 11 and the convex wall portion 12. The at least one positioning member 16 passes through the at least one positioning hole 15 to press and position the guide tube 2. In this embodiment, the number of the at least one positioning hole 15 is two, and the two positioning holes 15 are arranged in a straight line. The number of the at least one positioning member 16 is two, and the two positioning members 16 symmetrically clamp and press against the guide tube 2; wherein each positioning member 16 is a stop screw.

[0034] In more detail, the guide tube 2 further includes a first tube portion 22 and a second tube portion 23 which are assembled together. The diameter of the first tube portion 22 is larger than that of the second tube portion 23. The first tube portion 22 is accommodatingly set to be located in the tube body 11. One end of the second tube portion 23 extends into the first chamber 13 and is assembled to the first tube portion 22. The other end of the second tube portion 23 extends into the launch tube 4 to abut against a gunpowder nail 9. The first tube portion 22 does not protrude from the tube body 11, so that the tube body 11 can protect the first tube portion 22 from being touched by foreign objects. In this embodiment, in the radial direction of the tube body 11, the end surface of the convex wall portion 12 abuts against the outer side wall of the guide tube 2. The convex wall portion 12 can effectively restrain the guide tube 2 so that it can extend axially without any skewing.

[0035] The movable sleeve 3 is movably inserted into the first chamber 13 and sleeves the guide tube 2. The joint between the movable sleeve 3 and the guide tube 2 is located in the first chamber 13 to be protected by the tube body 11, so as to have better combination stability. The launch tube 4 is arranged at one end of the movable sleeve 3 away from the main tube 1. The gunpowder nail 9 is accommodated in the launch tube 4. The firing pin assembly 5 is movably inserted into the guide tube 2 to extend into the launch tube 4 to strike the gunpowder nail 9.

[0036] The drive assembly 6 is movably inserted into the second chamber 14 and connected to the firing pin assembly 5 to form a synchronous relationship. The above-mentioned combination method eliminates the traditional complex firing transmission structure configuration between the drive assembly 6 and the firing pin assembly 5, making the overall structure quite simple and easy to assemble; and when the user applies force to activate the drive assembly 6, there will be no resistance caused by the firing transmission structure itself, so the firing can be performed effortlessly and quickly. In this embodiment, the guide tube 2 is provided with a slide groove 21, and the drive assembly 6 includes a connecting sleeve 61, a driving rod 62 and a pin 63. One end of the connecting sleeve 61 is screwed to the driving rod 62, and the other end of the connecting sleeve 61 is sleeved on the guide tube 2. The pin 63 is passed through the slide groove 21 to connect the firing pin assembly 5 and the other end of the connecting sleeve 61. The pin 63 slides along the slide groove 21, so that the drive assembly 6 and the firing pin assembly 5 can slide relative to the guide tube 2.

[0037] The first elastic member 71 is accommodated in the first chamber 13, and the first elastic member 71 is elastically pressed between the movable sleeve 3 and the convex wall portion 12, so that the movable sleeve 3 has a tendency to move away from the convex wall portion 12. In actual use, when the user compresses the movable sleeve 3 and extends it into the first chamber 13 to remove the shell, the first elastic member 71 can restore the movable sleeve 3.

[0038] The second elastic member 72 is accommodated in the second chamber 14, and the second elastic member 72 is elastically pressed between the driving component 6 and the convex portion 12, so that the driving component 6 has a tendency to move away from the convex portion 12. Similarly, in actual use, when the user pushes the driving component 6 into the second chamber 14 for firing, the second elastic member 72 can reset the driving component 6.

[0039] The third elastic member 73 is accommodated in the guide tube 2, and the third elastic member 73 is elastically pressed between the inner wall of the guide tube 2 and the firing pin assembly 5. When the firing pin assembly 5 is driven by the driving assembly 6 to fire the gunpowder nail 9, the third elastic member 73 can assist the first elastic member 71 to reset the driving assembly 6 and the firing pin assembly 5.

[0040] In this embodiment, the first elastic member 71 and the second elastic member 72 are respectively passed through the two sides of the guide tube 2. The guide tube 2 can support the first elastic member 71 and the second elastic member 72 from the radial inner side and can guide them in the axial direction. The third elastic member 73 is located inside the guide tube 2 in the first chamber 13, so that the third elastic member 73 and the first elastic member 71 are coaxially arranged. In addition, the elastic force of the first elastic member 71 is greater than the elastic force of the second elastic member 72, so that the movable sleeve 3 and the launch tube 4 can remain protruding from the main tube 1 during the firing process of compressing the second elastic member 72 of the drive assembly 6, so as to effectively ensure that the shell ejection action will not be unexpectedly generated. In addition, the elastic force of the second elastic member 72 is greater than the elastic force of the third elastic member 73, so as to provide a certain support force to the drive assembly 6 to avoid easy misfire, so as to improve the safety of use.

[0041] It is worth mentioning that the driving assembly 6 is not connected to the actuation of the movable sleeve 3, and the two can be operated independently to reduce the linkage components and resistance during their respective operations. For example, when the driving assembly 6 is actuated, only the second elastic member 72 and the third elastic member 73 are compressed, and the resistance encountered by the user during the actuation process is smaller than that of the traditional structure, and when the shell is withdrawn and the movable sleeve 3 is compressed, the resistance only comes from the first elastic member 71. In addition, the elastic forces provided by the first elastic member 71 and the second elastic member 72 to the driving assembly 6 and the movable sleeve 3 are opposite, so when the driving assembly 6 and the movable sleeve 3 are to be assembled with the guide tube 2, the guide tube 2 must first be not positioned in the main tube 1, and then one side of the guide tube 2 can be made to protrude from the main tube 1 by compressing one of the first elastic member 71 and the second elastic member 72 for assembly.

[0042] Preferably, the ceiling nail driver further includes a silencer sleeve 81, which is disposed on the movable sleeve 3 and sleeves the launching tube 4. The silencer sleeve 81 is made of metal material and has better structural strength. The silencer sleeve 81 can effectively reduce the impact sound of the firing pin assembly 5 hitting the gunpowder nail 9 and the sound of the gunpowder explosion of the gunpowder nail 9; wherein, when the movable sleeve 3 approaches the convex wall portion 12 to the limit, the silencer sleeve 81 and the tube body 11 abut against each other to effectively limit the position.

[0043] Another preferred embodiment further comprises a heat-insulating sleeve 82, which covers the silencer sleeve 81 to isolate the firing tube 4 which becomes hot after firing from the outside world, so as to ensure the personal safety of the user.
