Description

Technical Field

[0001] This application relates to the field of magnetizing screw removal and assembly tools, and more particularly to a magnetizer and screwdriver set. Background Technology

[0002] In the field of power tools and hand tools, the magnetic adsorption function of screwdrivers is crucial for improving operational efficiency.

[0003] Magnetizers in related technologies are typically ring-shaped or sleeve-shaped structures, and are mostly designed based on a single radial screwdriver size, only compatible with screwdrivers of that size. However, different tool brands or models of screwdrivers have different diameters, and magnetizers with a fixed inner diameter cannot accommodate the needs of screwdrivers with multiple radial sizes. Users need to purchase multiple magnetizers to fit different radial screwdriver sizes, increasing usage costs. Furthermore, carrying multiple magnetizers takes up space in the toolbox, and small parts are easily lost or confused. This significantly impacts work efficiency, especially in complex work scenarios where tools are frequently changed. Utility Model Content

[0004] This application provides a magnetizer and screwdriver set to solve the technical problem of poor compatibility of magnetizers with fixed inner diameter dimensions.

[0005] The embodiments of this application provide the following technical solutions to solve the above-mentioned technical problems:

[0006] This application provides a magnetizer, which includes:

[0007] The first mating structure includes a first mating portion and two guide portions disposed opposite to and spaced apart from each other in the first mating portion. The first side of the guide portion is bent inward to form a limiting edge. The first mating portion is provided with a first magnetic suction member, which is disposed in the first mating portion between the two guide portions.

[0008] The second mating structure forms a magnetic hole for accommodating a screwdriver between the second mating structure and the first mating structure. The second mating structure has limiting protrusions on both opposite sides, and one end of each limiting protrusion has a blocking portion. At least the portion of the second mating structure with the limiting protrusion is located between the two guide portions, and the limiting protrusion corresponds to the limiting edge on the corresponding side. The limiting protrusion can move back and forth between the first mating portion and the limiting edge along the guide portion. The second mating structure has a second magnetic suction member, which is opposite to and repulsors the first magnetic suction member.

[0009] A blocking member is installed at one end of the second mating structure away from the blocking portion. The blocking member and the blocking portion cooperate to define the position of the second mating structure in a first direction, where the first direction is the direction in which the blocking portion points to the blocking member.

[0010] The beneficial effects of this application's embodiments are as follows: The magnetizer provided in this application's embodiments includes a first mating structure and a second mating structure, with a magnetizing hole formed between the first and second mating structures. The second mating structure can move relative to the first mating structure to change the size of the magnetizing hole in a first direction (the direction in which the second mating structure moves relative to the first mating structure), i.e., the size of the magnetizing hole is variable. This allows the magnetizer to be adapted to screwdrivers of various radial sizes. When the screwdriver is inserted into the magnetizing hole, the first magnetic attractor and the second magnetic attractor respectively attract the screwdriver, thereby causing the magnetizer to adhere to the screwdriver. Furthermore, this application's embodiments can assemble a magnetizer using only five components: the first mating structure, the second mating structure, the first magnetizer, the second magnetizer, and a blocking member. This reduces the number of components, facilitates assembly, and lowers the overall cost.

[0011] In one possible implementation, the number of limiting protrusions located on either side of the second mating structure is one, and the limiting protrusions cooperate with the side surface of the second mating structure to form an L-shaped groove.

[0012] The second mating structure slides between the two guide parts through an L-shaped groove, which accommodates the limiting edge on the corresponding side.

[0013] In one possible implementation, the distance between the outer surfaces of the two limiting protrusions is slightly smaller than the distance between the two guide portions.

[0014] In one possible implementation, one of the blocking member and the second mating structure at the end opposite to the blocking part is provided with a fixing hole, and the other is provided with a fixing protrusion. The fixing protrusion and the fixing hole cooperate to fix the blocking member in the second mating structure.

[0015] In one possible implementation, the blocking member is provided with a buckle, and the second mating structure is provided with a slot, the buckle engaging with the slot to assist in the connection between the blocking member and the second mating structure.

[0016] In one possible implementation, the first mating structure has a first notch and a second notch located on both sides of the guide portion, the first notch being configured to accommodate the blocking portion and the second notch being configured to accommodate the blocking member.

[0017] In one possible implementation, the first mating structure has a first notch located on one side of the guide portion, the first notch being configured to accommodate the blocking portion;

[0018] The magnetizer also includes a trimming component, which is installed at the end of the first mating portion opposite to the first notch, and the trimming component has the same structure as the blocking component.

[0019] In one possible implementation, the first mating portion is provided with a first receiving groove, the bottom of the first receiving groove is provided with a first mounting groove, and the first magnetic suction member is fixedly installed in the first mounting groove.

[0020] In one possible implementation, the second mating portion is provided with a second receiving groove, the bottom of the second receiving groove is provided with a second mounting groove, and the second magnetic suction member is fixedly installed in the second mounting groove.

[0021] This application also provides a screwdriver set, which includes at least one screwdriver and a magnetizer as described in any of the above embodiments.

[0022] The beneficial effects of the screwdriver set provided in this application embodiment are the same as those of the magnetizer described above, and will not be repeated here.

[0023] In addition to the technical problems solved by this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the magnetizer and screwdriver set provided by this application, other technical features contained in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0044] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] like Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, the magnetizer provided in this embodiment includes a first mating structure 100, a second mating structure 200, and a blocking member 400. The first mating structure 100 includes a first mating portion 110 and two guide portions 120 disposed opposite to and spaced apart from each other on the first mating portion 110. The first side of each guide portion 120 is bent inward to form a limiting edge 121. The first mating portion 110 is provided with a first magnetic attracting member 130, which is disposed within the first mating portion 110 between the two guide portions 120. A magnetic hole 300 for accommodating a screwdriver 600 is formed between the second mating structure 200 and the first mating structure 100. The second mating structure 200 has limiting protrusions 240 on both opposite sides, with a blocking portion 220 at one end. At least the portion of the second mating structure 200 with the limiting protrusions 240 is located between two guide portions 120, and the limiting protrusions 240 correspond to the corresponding limiting edges 121. The limiting protrusions 240 can move back and forth along the guide portions 120 between the first mating portion 110 and the limiting edges 121 to achieve adjustable aperture of the magnetic hole 300. The second mating structure 200 has a second magnetic attractor 230, which is opposite to and repulsors the first magnetic attractor 130. That is, after the second mating structure 200 and the first mating structure 100 are assembled, the second mating structure 200 can move along a second direction (e.g., ...). Figure 4 Moving back and forth in the X direction (as shown), when the magnetizer is installed on the screwdriver 600, both the first magnetic member 130 and the second magnetic member 230 attract the screwdriver 600. At this time, the second mating structure 200 moves towards the first mating portion 110, so that the first mating structure 100 and the second mating structure 200 are clamped on the screwdriver 600, thereby magnetizing the screwdriver 600 and enabling it to attract screws, etc. When the screwdriver 600 is removed from the magnetizer, the first magnetic member 130 and the second magnetic member 230 repel each other. Under the mutual repulsion of the first magnetic member 130 and the second magnetic member 230, the second mating structure 200 moves away from the first mating portion 110. The limiting edge 121 prevents the second mating structure 200 from moving out of the space between the two guide portions 120.

[0047] In this embodiment, the blocking member 400 is installed on the end of the second mating structure 200 opposite to the blocking portion 220. The blocking member 400 and the blocking portion 220 cooperate to define the position of the second mating structure 200 in a first direction, which is the direction in which the blocking portion 220 points to the blocking member 400 (e.g., Figure 4(Z direction in the first direction). That is, after the second mating structure 200 is assembled onto the first mating structure 100, the blocking member 400 is installed at the end of the second mating structure 200 away from the blocking part 220. The blocking member 400 prevents the second mating structure 200 from moving in the opposite direction of the first direction, while the blocking part 220 prevents the second mating structure 200 from moving in the first direction. That is, the blocking member 400 and the blocking part 220 cooperate to restrict the position of the second mating structure 200 in the first direction, so that it cannot move in the first direction.

[0048] The magnetizer provided in this embodiment can move relative to the first mating structure 100 via the second mating structure 200, thereby changing the size of the magnetizing hole 300 in the second direction. That is, the size of the magnetizing hole 300 is variable, allowing the magnetizer to be adapted to screwdrivers 600 of various radial sizes. This means users only need to purchase one magnetizer, which can adapt to screwdrivers 600 of different radial sizes, reducing the cost of purchasing magnetizers. Furthermore, since it adapts to screwdrivers 600 of various radial sizes, there is no need to worry about confusion during use. In addition, this embodiment can be assembled into a magnetizer using only five components: the first mating structure 100, the second mating structure 200, the first magnetizer, the second magnetizer, and the blocking member 400. This reduces the number of components, simplifies assembly, and lowers the overall cost.

[0049] like Figure 2 As shown, in some embodiments of this application, the number of limiting protrusions 240 located on either side of the second mating structure 200 is one. That is, the number of limiting protrusions 240 located on either side of the second mating structure 200 is not limited to one; it can be one or more. In this embodiment, multiple protrusions include two. For example, the number of limiting protrusions 240 located on either side of the second mating structure 200 is one. The limiting protrusion 240 cooperates with the side surface of the second mating structure 200 to form an L-shaped groove 210. The second mating structure 200 slides between the two guide portions 120 through the L-shaped groove 210, and the L-shaped groove 210 accommodates the corresponding limiting edge 121. That is, the L-shaped groove 210 and the limiting edge 121 cooperate so that the second limiting structure can move back and forth along the second direction and can also be restricted in position by the limiting edge 121.

[0050] like Figure 2 , Figure 4 and Figure 7 As shown, to avoid the second mating structure 200 in a third direction (such as...) Figure 4The distance between the outer surfaces of the two limiting protrusions 240 is slightly smaller than the distance between the two guide portions 120. In other words, the two guide portions 120 restrict the position of the second mating structure 200 in the third direction, and only a movement gap is left between the outer surfaces of the two limiting protrusions 240 and the two guide portions 120. Thus, the two guide portions 120 and the two limiting protrusions 240 cooperate to allow the second mating structure 200 to move back and forth along the second direction, and to prevent the second mating structure 200 from wobbling in the third direction.

[0051] like Figure 2 , Figure 7 and Figure 8 As shown, one of the ends of the blocking member 400 and the second mating structure 200 opposite to the blocking portion 220 is provided with a fixing hole 260, and the other is provided with a fixing protrusion 410. The fixing protrusion 410 and the fixing hole 260 cooperate to fix the blocking member 400 to the second mating structure 200. For example, the fixing protrusion 410 and the fixing hole 260 are interference-fitted so that the blocking member 400 is fixedly installed in the second mating structure 200.

[0052] To increase the stability of the blocking member 400 connected to the second mating structure 200, the blocking member 400 is provided with a buckle 420, and the second mating structure 200 is provided with a latch 270. The buckle 420 engages with the latch 270 to assist in the connection between the blocking member 400 and the second mating structure 200. That is, when the blocking member 400 is fixedly installed on the second mating structure 200, the fixing protrusion 410 is installed in the fixing hole 260, and the buckle 420 engages with the latch 270. The fixing protrusion 410 and the fixing hole 260 cooperate, and the buckle 420 and the latch 270 cooperate, so that the blocking member 400 is stably connected to the second mating structure 200.

[0053] like Figure 6 As shown, in some embodiments of this application, the first mating structure 100 has a first notch 140 and a second notch. The first notch 140 and the second notch are located on both sides of the guide portion 120. The first notch 140 is configured to accommodate the blocking portion 220, and the second notch is configured to accommodate the blocking member 400. The blocking portion 220 is placed in the first notch 140, and the blocking member 400 is placed in the second notch, thereby making the magnetizer more regular, well-shaped, and aesthetically pleasing.

[0054] In other embodiments of this application, such as Figure 2 and Figure 5As shown, the first mating structure 100 has a first notch 140, which is located on one side of the guide portion 120 and is configured to accommodate the blocking portion 220. The magnetizer also includes a finishing member 500, which is installed on the end of the first mating portion 110 opposite to the first notch 140. The finishing member 500 has the same structure as the blocking member 400. The blocking portion 220 is located in the first notch 140, and both the blocking member 400 and the finishing member 500 are installed on the side of the magnetizer opposite to the blocking portion 220. This arrangement makes the magnetizer more regular, well-shaped, and aesthetically pleasing. Furthermore, the finishing member 500 makes the appearance of the magnetizer more uniform, increases the variability of the appearance, and increases the selection of color matching for the magnetizer.

[0055] like Figure 5 and Figure 7 As shown, the first mating portion 110 is provided with a first receiving groove 150, and the bottom of the first receiving groove 150 is provided with a first mounting groove 160, in which a first magnetic attractor 130 is fixedly installed. The second mating portion is provided with a second receiving groove 280, and the bottom of the second receiving groove 280 is provided with a second mounting groove 290, in which a second magnetic attractor 230 is fixedly installed. The arrangement of the first mounting groove 160 and the second mounting groove 290 facilitates the installation of the first magnetic attractor 130 and the second magnetic attractor 230. The arrangement of the first receiving groove 150 and the second receiving groove 280 increases the size of the magnetizing hole 300 in the second direction, making the magnetizer more widely applicable or enabling a reduction in the thickness of the magnetizer in the second direction.

[0056] This application also provides a screwdriver set, which includes at least one screwdriver and a magnetizer for any of the above-described solutions.

[0057] The beneficial effects of the screwdriver set provided in this application embodiment are the same as those of the magnetizer described above, and will not be repeated here.

[0058] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
