Detailed Description

As shown in fig. 1-8, the power saving stapler of the present invention comprises: upper cover 1, be used for installing nail board 4, base 5 of nail way subassembly 2, upper cover 1 be equipped with supplementary clamp plate 3 outward,

supplementary clamp plate

3 and 1 sliding fit of upper cover, the upper cover is equipped with slider 1.1, supplementary clamp plate inner wall is equipped with guiding groove 3.1, slider 1.1 sliding fit is in guiding groove 3.1,

nail board

4 and 5 sliding fit of base, and be equipped with locking mechanism between nail board 4 and the base 5, locking mechanism including preceding locking mechanism and back locking mechanism, preceding locking mechanism and back locking mechanism be used for fixing a position nail board 4 and base 5 when different positions respectively. The structure is described in detail in Chinese patent CN109590948A, and the description is not repeated, and only needs to describe a sliding block structure in sliding fit with the auxiliary pressing plate in the embodiment.

The utility model discloses an innovation point lies in: the front locking mechanism comprises a button 7 and a pressure spring 8, the button 7 is in snap fit with the nail plate 4, and the pressure spring 8 is positioned between the nail plate 4 and the base 5; the rear locking mechanism comprises a baffle plate 9, and a stop block 10 used for abutting against the baffle plate 9 is arranged on the nail plate 4.

The core content is that the sliding of the nail plate and the base in the prior art needs manual operation to be changed into automatic springback under the action of the pressure spring, so that labor is saved, and the structure of the working chamber is stable.

As an improvement, for the convenience of manufacture and without affecting the traditional nail plate structure, the nail plate 4 is provided with an auxiliary plate 11, the auxiliary plate 11 is positioned below the nail plate 4, the nail plate 4 is fixedly connected with the auxiliary plate 11, and the auxiliary plate 11 is in sliding fit with the base 5. The installation of the nail plate is realized through the auxiliary plate, the influence on the nail plate structure can be effectively avoided, and the nail plate structure is more convenient to manufacture. The fixing form between the auxiliary plate and the nail plate is not limited, and screws, pins, welding and the like can be used. The base is provided with a pressure spring groove 16, the auxiliary plate is provided with a pressure spring seat 17, the pressure spring is positioned in the pressure spring groove 16, one end of the pressure spring is abutted against the base, and the other end of the pressure spring is abutted against the pressure spring seat 17, so that the auxiliary plate is driven by the pressure spring.

In a specific embodiment, the auxiliary plate 11 is provided with a chute 12, and the rear end of the chute 12 is a bayonet 13; the button 7 is positioned on the base 5, and the button 7 and the bayonet 13 are matched to form a front locking mechanism. The button is arranged on the base and clamped in the bayonet to realize the positioning of the nail plate, the pressure spring is in a compression state at the moment,

the front end of the sliding chute 12 is provided with a yielding port 14 which expands along the sliding chute 12. The clearance opening 14 is in smooth transition with the slide groove 12, so that the button can move between the slide groove and the clearance opening conveniently.

The base 5 on be equipped with slide 5.1, slide 5.1 be equipped with baffle 9, nail board 4 on be equipped with dog 10, baffle 9 and dog 10 offset and form back locking mechanism. During operation, the button is pressed to enable the button to be separated from a bayonet 13 at the bottom of the auxiliary plate, under the guide of the slide way 5.1, the auxiliary plate 11 moves backwards under the pushing of the pressure spring 8 until the baffle plate is abutted against the stop block for positioning, in the process, the upper cover and the auxiliary pressure plate move relatively through a sliding fit structure, so that the torque of the stapler can be prolonged, and the stapler can be operated by pressing the auxiliary pressure plate in a labor-saving manner.

In order to ensure that the button can be operated more reliably, a limiting spring 15 is arranged between the button 7 and the base 5, one end of the limiting spring 15 is connected with the base 5, and the other end of the limiting spring 15 is connected with the button 7. When the nail board is for removing, the button blocks with the bayonet socket, and spacing spring 15 is in natural state this moment, when pressing the button, the nail board moves backward, and spacing spring begins to compress, and the nail board moves backward makes the button be in the mouth position of stepping down, and the button can be by spacing spring 15 push fit in stepping down the mouth, and spacing spring is in natural state once more, can guarantee like this that the surface of button can keep on a plane with the lateral wall of base under the conventional condition, comparatively pleasing to the eye also the operation of being convenient for. Let the excessive structure of pitch arc between position mouth and the slide, this structure can guarantee to be pegged graft the board and can be in the removal that the round trip movement in-process button can be free at the both ends of slide, avoids blocking.
