Description

Technical Field

[0001] This application relates to the field of nail gun technology, and in particular to a nail length adaptation and adjustment mechanism for chain nail guns. Background Technology

[0002] Chain nail guns, short for chain-type screw guns, are widely used as efficient and convenient fastening tools in various industries such as construction, furniture manufacturing, and decoration for connecting various materials.

[0003] The positioning support plate is a device used for support and positioning on the chain nail gun. The extension length of the positioning support plate on the existing chain nail gun is usually not adjustable. Since the chain nail needs to be fed through the positioning support plate, when the chain nail gun is equipped with a non-adjustable positioning support plate, only screws of a specific length can be used. During operation, it is not possible to switch to use screws of different lengths, which lacks flexibility and is quite inconvenient.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a nail length adaptation and adjustment mechanism for a chain nail gun to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a nail length adaptation and adjustment mechanism for a chain nail gun, comprising: a head, including a housing, with guide grooves formed on both sides of the housing, wherein a receiving groove is formed in the middle of one of the guide grooves, and a nail length adjustment mechanism is provided on the head; a positioning support plate, sliding in the guide groove, having several interconnected locking holes thereon; the nail length adjustment mechanism is used to adjust the extension of the positioning support plate, and includes: an adjustment button, located on the top of the head, with its bottom connected to a spring, and a mounting plate extending downward from the side of the adjustment button near the receiving groove; a locking pin, one end of which is fixed on the mounting plate, and the other end extending out from the receiving groove and into the locking hole, for locking the positioning support plate; the nail length adjustment mechanism drives the locking pin to move downward in the receiving groove and disengage from the locking hole by pressing the adjustment button, thereby unlocking; after adjustment, releasing the adjustment button achieves reset and locking.

[0007] In some embodiments, the guide groove is formed by a pair of guide rails protruding from the housing, the pair of guide rails being arranged vertically, parallel to each other, and maintaining a horizontal position.

[0008] In some embodiments, the receiving groove begins at the middle of the guide groove, extends downwards, and cuts off the guide rail below.

[0009] In some embodiments, the positioning support plate is U-shaped, with its two ends sliding in guide grooves on both sides of the housing.

[0010] In some embodiments, the positioning support plate has an upper support plate and a lower support plate extending to one side at its end, and the upper support plate and the lower support plate are respectively attached to two adjacent guide rails.

[0011] In some embodiments, a sliding groove is provided on the lower support plate, which connects each of the locking holes and provides space for the locking pin to move.

[0012] In some embodiments, the locking hole is marked with a scale.

[0013] In some embodiments, the housing extends inward to form a mounting platform, and one end of the spring is fixed to the mounting platform.

[0014] In some embodiments, a boss is formed at the bottom of the adjustment button, and the other end of the spring is sleeved on the boss.

[0015] The beneficial effects of this application are as follows: the position of the positioning support plate can be adjusted by the adjustment button on the nail length adjustment mechanism to accommodate different types of chain nails. Pressing and holding the adjustment button drives the locking pin to move downward in the receiving groove. After disengaging from the locking hole, the positioning support plate can slide freely in the guide groove. After adjusting the positioning support plate to the appropriate position, releasing the adjustment button will cause the adjustment button to automatically reset under the action of the spring, and the locking pin will re-enter the corresponding locking hole. This achieves quick unlocking, adjustment, and locking of the positioning support plate, which is convenient and fast, and well adapts to the needs of changing chain nails of different lengths in complex working scenarios.
