[0002] With the development of the building decoration industry, the construction quality and efficiency of the suspended ceiling, as an important part of the interior space, directly affect the progress and aesthetics of the entire project. As an indispensable tool in the construction of suspended ceilings, the ceiling nailer is used to firmly drive various types of nails into the suspended ceiling materials to ensure the stability and safety of the suspended ceiling structure. However, the existing ceiling nailers have certain limitations in design, especially in adapting to complex working environments and meeting the diverse needs of operators.

[0003] The connection between the handle and the handle connector of a traditional ceiling nailer is mostly threaded or directly bolted. Although this type of fixed connection ensures the stability of the structure, it also limits the flexibility of the handle. Specifically, the handle is fixed in position and cannot be adjusted according to the operating scenario. Especially when facing narrow spaces, restricted operating areas, or when firing at a specific angle, the fixed handle shape often leads to inconvenience in operation and even affects the accurate implantation of the nail and work efficiency. In addition, since it cannot rotate, the handle may collide with surrounding obstacles, increasing the risk of operation. It may also reduce the comfort of holding because it cannot adapt to operators of different body shapes and habits.

[0004] In view of the above problems, the current ceiling nail fixers on the market have obvious deficiencies in adaptability, humanized design and ease of operation, and are difficult to fully meet the needs of modern construction projects for efficient, flexible and safe construction tools. Therefore, it is urgent to develop a new type of ceiling nail fixer, whose handle can be flexibly rotated and angle locked, so that the nail fixation operation can be performed conveniently and accurately in various complex working environments, while improving the operating comfort and work efficiency of operators and reducing construction risks.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] The utility model provides a handle rotation adjustment type ceiling nail fixing device.

[0029] In this embodiment, refer to Figure 1-5 The handle rotation and adjustment type ceiling nail fixing device includes a grip connector 1 and a grip 2, the grip and the grip connector are rotationally connected, and also includes a locking mechanism 3. When the locking mechanism is in an unlocked state, the grip can freely rotate 360° around the axis of the grip connector. When the grip is rotated to a preset angle, the locking mechanism can position and fix the grip so that the grip can rotate.

[0030] In the above structure, the handle and the handle connector are connected in a rotating manner and are equipped with a locking mechanism. When the locking mechanism is in the unlocked state, the handle can achieve 360° full-range free rotation around the axis of the handle connector to adapt to different working environments and operator needs. Once the handle is adjusted to a preset angle, the locking mechanism can effectively fix it to prevent the handle from accidentally rotating during use. The setting of the above structure gives the nail fixer handle height adjustability, allowing the tool to easily adapt to narrow spaces, complex angles and restricted operating areas, greatly improving the convenience of operation. The locking mechanism locks the handle at a preset angle, ensuring the stability and accuracy of the firing action, which helps to improve the accuracy and work efficiency of the nail fixing operation.

[0031] Specifically, a connecting convex ring 4 is provided on one end of the handle connector, a connecting concave ring 6 is provided on the outer ring of the connecting convex ring, and an annular step 7 which is inserted into and rotatably cooperates with the connecting concave ring is provided on the end of the handle connected to the handle connector.

[0032] In this embodiment, the mutual cooperation between the connecting convex ring and the connecting concave ring, and the rotational engagement between the annular step and the connecting concave ring, form a stable rotational connection structure, ensuring that the handle will not loosen during the rotation process, thereby ensuring the safety of the tool in use.

[0033] Specifically, the locking mechanism includes a button 8 and a return spring 9. The button is telescopically matched with the mounting hole 10 on the handle. The return spring is used to freely rebound to its original position after the button is pressed and released. The button is provided with a positioning locking rod 11, and at least two opposing positioning grooves 12 are provided on the inner wall of the through hole of the connecting convex ring.

[0034] In this embodiment, the locking mechanism includes a button 8, a reset spring 9, a positioning lock rod and a positioning groove 12. When the button is pressed, the positioning lock rod exits the positioning groove, and the handle can rotate freely; when the button is released, the reset spring drives the button to reset, and the positioning lock rod re-embeds into the positioning groove to achieve the positioning and fixing of the handle. The handle can be unlocked and locked with one-touch operation, which is intuitive and quick to operate, greatly improving the user experience.

[0035] Specifically, there are a plurality of positioning grooves which are arranged at equal intervals on the inner wall of the through hole connecting the convex ring.

[0036] Multiple equally spaced positioning slots provide more preset angle options, allowing the handle to be finely adjusted in smaller angle increments to meet more refined operation needs. Users or companies can set the position and number of positioning slots as needed. The conventional and commonly used ones are mostly two directly opposite settings, which can be positioned in two states, such as Figure 4 and Figure 5 Two states are shown.

[0037] Specifically, a spring step 13 is provided in the handle, a spring hole 14 is provided on the button, the reset spring is arranged in the spring hole, and the bottom of the reset spring is connected to the spring step.

[0038] The reset spring is built into the spring hole of the handle and forms an integrated structure with the button, which not only saves space, but also makes the overall appearance more concise, which is conducive to the miniaturization design of the tool. The spring and the internal structure of the handle are closely matched to avoid the spring from shifting or failing during use, ensuring the long-term stable operation of the locking mechanism.

[0039] Specifically, a guide groove 15 is provided on one side of the handle mounting hole, and a guide step 16 that slidably cooperates with the guide groove is provided on the side of the button.

[0040] The cooperation between the guide groove and the guide step effectively guides the movement trajectory of the button, ensuring a smooth pressing process without jamming, and improving the operating feel. The guide structure limits the movement direction of the button to prevent the button from deflecting or distorting during the pressing process, which can effectively extend the service life of the button and related components.

[0041] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
