[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.
[0031] Example:
[0032] like Figures 1 to 3As shown, this utility model provides a multifunctional nail remover, including: a first clamping assembly 1, a second clamping assembly 2, and a shell removal assembly. The first clamping assembly 1 includes a first clamping handle 101, a first fixed tooth 102, a first movable tooth 103, and a first distance adjustment assembly. The first fixed tooth 102 is fixedly installed at the first end of the first clamping handle 101, and the first movable tooth 103 is slidably disposed at the first end of the first clamping handle 101 via the first distance adjustment assembly, so that the distance between the first fixed tooth 102 and the first movable tooth 103 is adjustable. The second clamping assembly 2 includes: The device includes a second clamping handle 201, a second fixed tooth 202, a second movable tooth 203, and a second adjusting assembly. The second fixed tooth 202 is fixed to the first end of the second clamping handle 201, and the second movable tooth 203 is slidably disposed at the first end of the second clamping handle 201 via the second adjusting assembly, so that the distance between the second fixed tooth 202 and the second movable tooth 203 is adjustable. The second end of the second clamping handle 201 is hinged to the second end of the first clamping handle 101. Through the above arrangement, the distance between the movable tooth and the fixed tooth can be adjusted, so that this staple remover can be adapted to staples of different widths.
[0033] The shelling assembly includes a first serrated portion 3 and a second serrated portion 4. The first serrated portion 3 is disposed on the side of the first clamping handle 101 near the second clamping handle 201, and the second serrated portion 4 is disposed on the side of the second clamping handle 201 near the first clamping handle 101, so that a shelling space is formed between the first serrated portion 3 and the second serrated portion 4. By placing sunflower seeds, peanuts, etc., into the shelling space and then squeezing the two clamping handles, shelling can be achieved quickly, avoiding hand and tongue injuries caused by opening peanut shells by hand or directly opening sunflower seed shells with the mouth, saving time and effort.
[0034] This device easily opens peanut shells and various sunflower seed shells, avoiding the blisters, mouth ulcers, and tooth damage that can occur when opening shells with your mouth or hands. It satisfies people's love of snacks during leisure time. This device has strong promotional value in home, office, and school settings, with flexible application ideas, simple construction, low production cost, and convenient portability.
[0035] In this embodiment, the first fixed tooth 102 and the first movable tooth 103 gradually widen in the direction away from the first clamping handle 101 and towards the first clamping handle 101, forming a curved, pointed tooth shape. The shapes of the second fixed tooth 202 and the second movable tooth 203 are exactly the same as those of the first fixed tooth 102 and the second movable tooth 103. The first fixed tooth 102 and the second fixed tooth 202, and the first movable tooth 103 and the second movable tooth 203 are staggered and fitted together. When the staple is pulled out, the several staple-pulling teeth stagger and fit into the staple hole, allowing the staple to be pulled out quickly.
[0036] Specifically, the surfaces of the first clamping handle 101 and the second clamping handle 102 can be covered with a flexible material to protect the user's fingers. Protective sleeves can also be provided to cover the fixed and movable teeth when not used for nail removal, preventing scratches to the fingers during shell removal.
[0037] refer to Figure 1 , Figure 3 and Figure 4 A slide rail 12 is formed near the first end of the first clamping handle 101. The first adjustable distance component includes a sliding post, which is slidably disposed within the slide rail 12. The first movable tooth 103 is fixed to the sliding post to slide with the sliding post, thereby adjusting the distance between the first fixed tooth and the first movable tooth. Specifically, the slide rail 12 includes positioning points 5 and channels 6. Adjacent positioning points 5 are connected by channels 6, and the inner diameter of the positioning point 5 is larger than the width of the channel 6. The sliding post includes a column body 7 and limiting blocks 8 located at both ends of the column body 7. The first movable tooth 103 is fixedly connected to the column body 7. The column body 7 is slidably disposed within the channel 6, and the limiting blocks 8 are used to prevent the column body 7 from dislodging along the positioning points 5. The main staple sizes are 24 / 6 (outer width 12.66-12.75mm) and 10# (outer width 9.20-9.35mm). For these two staple sizes, there can be two positioning points. The distances between the two positioning points 5 and the fixed teeth are 9mm and 12mm, respectively. The column 7 drives the moving teeth to slide and stop at the corresponding positioning point. Press the limit block at the top of the column 7 with your finger to prevent it from shifting. At this time, the distance between the moving teeth and the fixed teeth is exactly the matching distance of the corresponding staple. By setting the positioning points, the position of the moving teeth can be quickly determined so that they can be matched with the corresponding staples.
[0038] When the staple width is between 9-12mm, a positioning point at the 9mm position can be selected. When the staple width is greater than 12mm, a positioning point at the 12mm position can be selected. Therefore, in practical implementation, setting two positioning points can satisfy staples of all widths. However, this embodiment does not limit the number of positioning points; they can be set according to the actual situation, as long as it is convenient to operate.
[0039] like Figure 4The diagram shows the connection between the first movable tooth 103 and the sliding column. The first movable tooth 103 includes a connecting piece 104 and a tooth tip 105 connected together. The connecting piece 104 is located near the upper end of the column 7 and is fixedly connected to the column. The connecting piece 104 is located on the lower surface of the first clamping handle. There is a gap between the connecting piece 104 and the limiting block above the column 7. This gap is slightly larger than the thickness of the first clamping handle, allowing the column above the connecting piece 104 to slide along the slide. In another embodiment, the connecting piece 104 can be fixedly connected to the column, and the connecting piece 104 is located on the upper surface of the first clamping handle, so that the column below the connecting piece 104 can slide along the slide. In this embodiment, "upper" and "lower" refer to the relative positions shown in the accompanying drawings and do not represent the relative positions during actual operation.
[0040] The above description is based on the first clamping assembly 1, the first clamping handle 101, the first fixed tooth 102, the first movable tooth 103, and the first distance adjustment assembly. Those skilled in the art should understand that the structure of the second clamping assembly 1, the second clamping handle 201, the second fixed tooth 202, the second movable tooth 203, and the second distance adjustment assembly is the same, and will not be repeated here.
[0041] like Figure 3 and Figure 5 As shown (please note that the accompanying drawings in this embodiment are only schematic diagrams used to illustrate the relative positional relationships of the components), it also includes an angle adjustment assembly, which includes an adjusting bolt 9, a nut 10, and a spring 11; bolt holes 13 are provided at the second end of the first clamping handle 101 and the second end of the second clamping handle 201; the adjusting bolt 9 is disposed in the bolt hole 13 and fixed by the nut 10; the spring 11 is arranged around the outer periphery of the adjusting bolt 9, with the first end of the spring 11 contacting the inner side of the first clamping handle 101 and the second end of the spring 11 contacting the inner side of the second clamping handle 201. By tightening or loosening the nut, the opening size between the first clamping handle and the second clamping handle can be adjusted to correspond to the different spaces required for sunflower seeds and peanuts, making the nail remover easier to use. The opening angle range between the first clamping handle and the second clamping handle is 0°~60°.
[0042] In this embodiment, a shim (not shown in the figure) is also included. The shim is disposed between the first end of the spring 11 and the first clamping handle 101, and between the second end of the spring 11 and the second clamping handle 201. By providing the shim, the stability of the spring can be improved.
[0043] Specifically, the first sawtooth section 3 includes a plurality of sawtooths 301 arranged in sequence, and the height of the plurality of sawtooths 301 decreases sequentially from both ends to the middle. Specifically, the plurality of sawtooths constituting the first sawtooth section are distributed with a lower center and higher sides, and the sawtooths on the sides are inclined towards the center. The above arrangement facilitates the clamping of sunflower seeds and peanuts, and better completes the shelling. In order to make this device adaptable to different sizes of sunflower seeds and peanuts, the first sawtooth section is arranged along the central axis of the first clamping handle and the second sawtooth section is arranged along the central axis of the second clamping handle. Moreover, the first clamping handle and the second clamping handle are different from existing nail removers, and their inner surfaces are not provided with grooves to prevent fragments of sunflower seeds and peanuts from falling in and making cleaning difficult.
[0044] In specific implementation: the height range of the plurality of saw teeth 301 is 4~10mm. The first saw tooth portion 3 occupies one-half to three-quarters of the length of the first clamping handle 101. The first end of the first saw tooth portion 3 is disposed close to the first end of the first clamping handle 101, so that the second end of the first saw tooth portion 3 is far away from the second end of the first clamping handle 101, preventing the saw tooth portion from affecting the two clamping handles when they are close together. The structure of the second saw tooth portion and the positional relationship between the second saw tooth portion and the second clamping handle are the same as those of the first saw tooth portion and the first clamping handle, and will not be described again here.
[0045] When using this device to remove nails:
[0046] According to the size of the staple, the user moves the movable teeth to the appropriate positioning point. Using one hand, the index finger and thumb are placed on the two gripping handles respectively, pressing down on the movable teeth to prevent displacement. The user then firmly pinches the two gripping handles, causing the corresponding two fixed teeth and two movable teeth to align and insert into the holes of the staple body until they cross and abut. Finally, pulling vertically will remove the staple. When not using the staple remover, a staple remover protective cover can be added to enclose it.
[0047] When using this device to remove the shell:
[0048] When shelling peanuts, users place the peanuts with shells on the side into the shelling space and pinch the two gripping handles up and down with their fingers to remove the peanut shells. When shelling various sunflower seeds, the seeds are placed on the side in the same way. Depending on the size of the sunflower seed shells, they can be placed in the corresponding areas of different height serrations and the shells can be removed by pinching them up and down.
[0049] This device has a simple design and is easy to carry. It will not hurt your hands when removing nails. When eating peanuts and melon seeds, it will not hurt your hands and will protect the smoothness of your teeth. It will not cause mouth ulcers caused by peeling shells with your mouth and tongue. It also reduces labor intensity. It can be widely used in home, office and study life. Whether it is removing nails or peeling shells, it saves time and effort.
[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
