[0038] Example 1
[0039] like Figures 1 to 3 The embodiment of this application shows a novel multifunctional nail puller, including: a housing 1 with a nail puller 2 and a screwdriver 3 respectively at both ends; the screwdriver 3 is detachably connected to the housing 1; the housing 1 has a first groove 11 for accommodating the screwdriver 3; a detachable first plate 15 is provided at the opening of the first groove 11; the first plate 15 covers the opening of the first groove 11, and the first plate 15 has a scale 151.
[0040] In a preferred embodiment provided in this application, the housing 1 is provided with a first groove 11 for receiving the screwdriver 3. The opening of the first groove 11 is covered by a detachable first plate 15. The first plate 15 is slidably fitted into a second groove 12 on the side wall of the housing 1. The first groove 11 is located at the bottom of the second groove 12.
[0041] The dimensions of the first plate 15 match those of the second groove 12. One end of the first plate 15 is provided with a protruding snap-fit piece 152. One end of the second groove 12 is open. The first plate 15 slides into the second groove 12 along the opening and is engaged and fixed with the first interface 13 on the inner wall of the other end of the second groove 12 by the snap-fit piece 152, so as to realize the quick assembly and disassembly of the first plate 15.
[0042] Furthermore, a third groove 14 is provided on one inner wall of the second groove 12, extending along the length of the second groove 12; a first auxiliary member 153 matching the third groove 14 is provided on the side of the first plate 15, the first auxiliary member 153 being a protruding strip protruding relative to the first plate 15. When the first plate 15 slides into the second groove 12, the protruding strip slides into the third groove 14, restricting the lateral displacement of the first plate 15 and enhancing the fixation stability.
[0043] The screwdriver 3 has a regular hexagonal rod 31, with a Phillips head 32 at one end and a flathead head 33 at the other end. One end of the housing 1 has a corresponding hexagonal mounting hole 16 for the screwdriver 3. The rod 31 of the screwdriver 3 is inserted into the mounting hole 16, and quick installation and removal are achieved through the friction of the polygonal contour. When the screwdriver 3 is not in use, it can be stored in the first slot 11, and the slot opening is covered by the first plate 15 to prevent the screwdriver 3 from falling out during transport.
[0044] The side of the first plate 15 facing away from the first groove 11 is provided with a scale 151. The user can directly use the scale 151 to measure the length, or the first plate 15 can be removed to measure the length using the scale 151. In addition, a second auxiliary member 4 is provided on the side of the housing 1. One end of the second auxiliary member 4 is connected to the housing 1, and the other end of the second auxiliary member 4 is set with a pointed tip and extends along the length direction of the housing 1. The pointed tip of the second auxiliary member 4 is spaced apart from the surface of the housing 1. A letter opener 41 is provided on the side of the second auxiliary member 4 near the housing 1.
[0045] The nail puller 2 is fixed to the other end of the housing 1 by a threaded connection. Its front end is provided with a "U"-shaped nail puller head. Users can disassemble and replace nail pullers 2 of different specifications as needed to accommodate nails of different sizes.
[0046] When the screwdriver function is needed, slide the first plate 15 to disengage it from the second slot 12, remove the screwdriver part 3 and insert it into the mounting hole 16, then rotate the housing 1 to operate; after use, put the screwdriver part 3 back into the first slot 11 and re-fix the first plate 15. When measuring length, directly read the scale 151 on the first plate 15, or remove the first plate 15 for measurement; when opening envelopes or packages, use the second auxiliary part 4 on the side of the housing 1 and the letter opener 41 to complete the operation.
[0047] In this embodiment, the screwdriver 3 is safely stored by the design of the first groove 11 and the detachable first plate 15, preventing it from falling off and being lost. The design of the second groove 12 nesting the first groove 11 allows the first plate 15 to be completely embedded in the housing 1, reducing the overall volume and making it easy to carry. The surface of the first plate 15 is provided with a scale 151, which integrates the length measurement function, improving the practicality and ease of operation of the device. At the same time, the screwdriver 3 adopts a double-head design, which is suitable for a variety of usage scenarios. The plug-in installation enables quick assembly and disassembly. Combined with the detachable screw remover 2 and the fixed screwdriver 41, the device's functional diversity is expanded to meet the needs of multiple tasks.
