Dual-purpose plastic frame

Abstract

The utility model provides a dual-purpose plastic frame which comprises a plastic frame body and a limiting piece, first limiting parts which can be used for placing tools and are matched with the tools are arranged on the plastic frame body in pairs, the limiting piece is connected to the plastic frame body in a sliding mode, and second limiting parts which can abut against the tools in the first limiting parts are arranged on the limiting piece. The limiting piece can slide on the plastic frame body, the position relation between the second limiting part on the limiting piece and the tool is changed along with movement of the limiting piece, and the two states of contact and separation exist. When the tool is separated from the second limiting part and is only limited by the first limiting part, the tool is in a loose matching state on the plastic frame; and when the second limiting part is in contact with the tool, the tool is tightly jacked, and pre-tightening force is generated to enable the tool to be in a close-fitting state on the plastic frame. Therefore, the working state of the dual-purpose plastic frame can be switched to adapt to different application scenes, and the dual-purpose plastic frame is more convenient to use.

Description

Technical Field

[0001] The utility model relates to a tool storage device, more specifically, it relates to a dual-purpose plastic frame. Background Art

[0002] Common hand tools often come in a variety of sizes and are often sold, used, and stored in sets. For example, wrenches come in a variety of opening sizes to accommodate different nut sizes. A common way to store these multi-size products is with a plastic rack. When selling or working outside, the entire tool set is often carried in a plastic rack. In this case, the tools require a certain degree of tightening force to prevent them from falling or moving. In other work scenarios, the plastic rack is often placed flat at the site of use. In this case, the tools need to be easily accessible, so they need to be loosely mounted on the rack. Existing plastic racks on the market typically have only a single function and cannot flexibly switch between tight and loose fits between the tool and the rack according to changing application scenarios, making them inconvenient to use. Utility model patent publication number CN214213748U discloses a wrench rack that not only facilitates the storage of multiple wrenches of different sizes and models, but also allows users to easily access the appropriate wrench, thereby improving work efficiency. However, this utility model does not have the function of switching between tight and loose fits between the tool and the rack. Utility Model Content

[0003] The existing tool storage plastic rack has a single function and cannot convert the tight fit and loose fit between the tool and the plastic rack. To overcome this defect, the utility model provides a dual-purpose plastic rack that can flexibly convert the tight fit and loose fit between the tool and the plastic rack according to changes in application scenarios, making it more convenient to use.

[0004] The technical solution of the present utility model is a dual-purpose plastic frame comprising a plastic frame body and a retaining member. The plastic frame body is provided with a pair of first retaining members for placing and cooperating with tools. The retaining member is slidably connected to the plastic frame body. The retaining member is provided with a second retaining member, which complements the first retaining member in stopping the tool in the unrestricted direction and cooperates with the first retaining member to prevent the tool from disengaging from the plastic frame body. The retaining member slides on the plastic frame body. As the retaining member moves, the positional relationship between the second retaining member and the tool changes, resulting in two states: blocking and disengaging. When the tool is disengaged from the second retaining member and retained only by the first retaining member, the tool is in a loose fit on the plastic frame when only engaging the first retaining member. When the second retaining member contacts the tool, it presses against the tool, generating a preload force that forces the tool into a tight fit on the plastic frame. Therefore, the dual-purpose plastic frame can switch between different working states to adapt to different application scenarios, making it more convenient to use.

[0005] Preferably, the second limiting portion is an elastic member. When the second limiting portion is deformed, it can provide a rebound force, which acts on the tool to become a pre-tightening force of the tool.

[0006] Preferably, the stopper is a plastic component, and the second stopper is an arched structure integrally formed with the stopper. The plastic arched structure exhibits significant elastic reset characteristics, ensuring the second stopper's functionality. Furthermore, the plastic stopper is wear-resistant and cost-effective, making it suitable for use in stoppers that frequently slide on a plastic frame body.

[0007] Preferably, a concave deformation portion is provided on the top of the second limiting portion. The second limiting portion with the concave deformation portion has a larger deformation amount and can provide better deformation preload force.

[0008] Preferably, a convex portion is provided on the top of the second limiting portion. The gear convex portion makes it easier for the second limiting portion to contact with tools of different specifications and can better provide pre-tightening force.

[0009] Alternatively, the second stopper can be a raised stopper protruding from the surface of the stopper and capable of stopping the side edge of the tool within the first stopper. The second stopper can also be in the form of a raised stopper. As the stopper moves, the raised stopper engages or disengages from the side edge of the tool within the first stopper. When the raised stopper stops the side edge of the tool, combined with the constraint exerted by the first stopper on the tool, a tight fit can be achieved on the plastic frame. When the raised stopper moves away from the side edge of the tool, the tool is restored to a loose fit on the plastic frame.

[0010] Preferably, the stopper is provided with a shift projection on its side, and the plastic frame body is provided with a shift groove that mates with and engages with the shift projection. The stopper has two shift positions relative to the plastic frame body, corresponding to the tight and loose fit between the tool and the plastic frame. The shift groove serves as a shift completion indicator. When the stopper moves until the shift projection engages the shift groove, resistance increases, making further movement of the stopper difficult.

[0011] Preferably, the plastic frame body comprises a back support and a retaining member clip. The retaining member clips are fixed to both sides of the back support, with a gap between the retaining member and the back support surface, and the retaining member slides within the gap. The back support provides back support for the retaining member, while the retaining member clips limit the position of the retaining member's top surface. The retaining member is located within the gap between the retaining member clips and the back support, allowing it to slide without detaching from the plastic frame body.

[0012] Preferably, the plastic frame body has a frame, and the back support includes a plurality of slats fixed to the frame. The back support can be composed of a plurality of slats without a complete plate, which can save the material of the back support and reduce the cost.

[0013] Preferably, the first stopper includes two groove walls that form a tool-engaging groove with a narrow opening and a wide base. The first stopper's narrow opening and wide base structure allows for a flatter tool, such as a common wrench, to be removed with a fixed direction even when the tool is loosely engaged with the first stopper, thereby ensuring both anti-dislocation and easy removal.

[0014] Preferably, a handle is provided on the plastic frame body to facilitate carrying and gripping, thereby improving the portability of the dual-purpose plastic frame.

[0015] The beneficial effects of the utility model are:

[0016] The tight and loose fit states between the tool and the plastic frame can be flexibly converted according to changes in application scenarios, taking into account different requirements for tool states in different application scenarios, making it more convenient to use.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the specific embodiments of the drawings.

[0030] Example 1:

[0031] like Figures 1 to 7 As shown, a dual-purpose plastic frame is used to store a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a limiting member 2. The plastic frame body 1 is provided with a first limiting portion 101. The first limiting portions 101 are arranged in pairs, and the number of first limiting portions 101 is determined by the number of specifications of the set of wrenches. In this embodiment, there are twelve pairs of first limiting portions 101, corresponding to twelve types of wrenches 3 with opening sizes ranging from 8 to 19 mm. The two first limiting portions 101 in each pair are located on both sides of the plastic frame body 1 and cooperate with the handle of the wrench 3. The first limiting portion 101 includes two groove walls, which form a tool insertion groove 109 with a small mouth and a large bottom, which can accommodate the handle of the wrench 3. The top of one of the groove walls has a hook-shaped structure, which acts as a block for the handle of the wrench 3 inserted into the first limiting portion 101. When the wrench 3 is removed, the thinner part of the handle of the wrench 3 must be aligned with the groove of the first limiting portion 101 before it can be removed. The limiting member 2 is slidably connected to the plastic frame body 1. The limiting member 2 is provided with a second limiting portion 201, which can tighten the wrench 3 within the first limiting portion 101. The plastic frame body 1 is trapezoidal in shape, wide at one end and narrow at the other. From the narrow end to the wide end, the size of the wrenches stored and arranged increases accordingly, i.e., the closer to the wide end, the larger the size of the wrenches stored and arranged. The wide end of the plastic frame body 1 is provided with a handle portion 102. The handle portion 102 is integrally formed with the plastic frame body 1 and has a roughly trapezoidal frame structure. It has a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface to improve the feel of the hand. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upper arrow and "unclip" indicate that the limit member 2 can be moved from the narrow end to the wide end of the plastic frame body 1 to release the cooperation between the second limit member 201 and the wrench 3, thereby achieving a loose fit between the wrench 3 and the dual-purpose plastic frame; the lower arrow and "clip" indicate that the limit member 2 can be moved from the wide end to the narrow end of the plastic frame body 1 to achieve a tight fit between the second limit member 201 and the wrench 3.

[0032] Correspondingly, the retaining member 2 is also designed to be roughly wide at one end and narrow at the other to better match the plastic frame body 1. However, there are equal-width sections at both the narrow end and the middle of the retaining member 2. Within these equal-width sections, the two sides of the retaining member 2 are parallel, ensuring that the retaining member 2 can slide in a straight line. The second retaining portion 201 is a resilient arched structure. The retaining member 2 is made of PET plastic and is integrally injection-molded with the retaining member 2. Two parallel, strip-shaped protrusions 203 are provided on the top of the second retaining portion 201. A shifting protrusion 204 is provided on the side of the retaining member 2. The plastic frame body 1 is provided with a shifting groove 110. The shifting groove 110 matches the shifting protrusion 204, forming a nested fit with the shifting protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a retaining plate 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms a lateral limit for the retaining member 2. The retaining member 2 slides within the area defined by the vertical step surface, the back support 104, and the retaining plate 103. When the edge of the retaining member 2 abuts the vertical step surface, the retaining member 2 reaches its limit of movement, leaving only the return degree of freedom. The retaining plate 103 is positioned on the frame 105 on both sides of the back support 104 via support plates, with a gap between the retaining plate 103 and the surface of the back support 104. The retaining member 2 slides within this gap. The retaining plate 103 and the support plates form an L-shape. The frame 105, back support 104, retaining plate 103, and the support plates are integrally formed. The back support 104 comprises eleven parallel slats, each connected to the frame 105 at both ends. The slats are integrally formed with the frame 105. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. A convex undercut 205 is integrally formed on the bottom surface of the narrow end of the stopper 2. This undercut 205 is located outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the undercut 205 acts as a limit stop. When the undercut 205 abuts the frame 105, the stopper 2 reaches its limit. The plastic frame body 1 also has a hanging hole 106, which can be used to hang the plastic frame body 1.

[0033] This dual-purpose plastic frame has two working gears, corresponding to the tight and loose states between the tool and the plastic frame. In scenarios such as when the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the workplace, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the wrench 3 is tightened by the second limiting part 201 and at the same time is pressed by the first limiting part The limiting part 201 is supported by the positioning part 101 to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, the user pushes the limiting part 2 according to the upper arrow and the "unclip" instruction until the edge of the limiting part 2 is in contact with the vertical step surface. At this time, the dual-purpose plastic frame is switched to another working gear. At this gear, when the wrench 3 is disengaged from the second limiting part 201 and is only limited by the first limiting part 101, the wrench 3 and the plastic frame are loosely fitted due to the fit between the wrench 3 and the first limiting part 101.

[0034] Example 2:

[0035] A dual-purpose plastic frame for storing a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a limiting member 2. The plastic frame body 1 is provided with a first limiting portion 101. The first limiting portions 101 are arranged in pairs. Unlike Example 1, there are ten pairs in this embodiment, corresponding to ten sizes of wrenches 3 with opening sizes ranging from 8 to 17 mm. The two first limiting portions 101 in each pair are located on either side of the plastic frame body 1 and cooperate with the handle of the wrench 3. The first limiting portion 101 includes two groove walls, which form a tool slot 109 with a small opening and a large bottom, allowing the handle of the wrench 3 to be inserted. The top of one of the groove walls is a hook-shaped structure, which blocks the handle of the wrench 3 inserted into the first limiting portion 101. This allows the wrench 3 to be removed by aligning the thinner portion of the handle of the wrench 3 with the slot of the first limiting portion 101. The limiting member 2 is slidably connected to the plastic frame body 1. The limiting member 2 is provided with a second limiting portion 201, which can tighten the wrench 3 within the first limiting portion 101. The plastic frame body 1 is trapezoidal in shape, wide at one end and narrow at the other. From the narrow end to the wide end, the size of the wrenches stored and arranged increases accordingly, i.e., the closer to the wide end, the larger the size of the wrenches stored and arranged. The wide end of the plastic frame body 1 is provided with a handle portion 102. The handle portion 102 is integrally formed with the plastic frame body 1 and has a roughly trapezoidal frame structure. It has a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface to improve the feel of the hand. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upper arrow and "unclip" indicate that the limit member 2 can be moved from the narrow end to the wide end of the plastic frame body 1 to release the cooperation between the second limit member 201 and the wrench 3, thereby achieving a loose fit between the wrench 3 and the dual-purpose plastic frame; the lower arrow and "clip" indicate that the limit member 2 can be moved from the wide end to the narrow end of the plastic frame body 1 to achieve a tight fit between the second limit member 201 and the wrench 3.

[0036] Correspondingly, the limiting member 2 is also made into a shape with one end wide and the other end narrow to better match the plastic frame body 1. However, there is a section of equal width at the narrow end and the middle of the limiting member 2. The two sides of the limiting member 2 are parallel in the equal width section to ensure that the limiting member 2 can slide along a straight line. The second limiting portion 201 is a resilient arched structure. Unlike the embodiment 1, the top of the second limiting portion 201 in this embodiment is provided with a concave deformation portion 202, such as Figure 8As shown. The stopper 2 is made of PET plastic. The second stopper 201 and the stopper 2 are integrally injection-molded. Two parallel strip-shaped protrusions 203 are provided on the top of the second stopper 201. A shifting protrusion 204 is provided on the side of the stopper 2. A shifting groove 110 is provided on the plastic frame body 1. The shifting groove 110 matches the shifting protrusion 204 and can form a nested fit with the shifting protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a stopper clip 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms the side limit of the stopper 2. The stopper 2 slides within the area defined by the vertical step surface, the back support 104, and the stopper clip 103. When the edge of the stopper 2 contacts the vertical step surface, the stopper 2 reaches its limit of movement, and the only degree of freedom left is the return movement. The stopper clips 103 are positioned on the frames 105 on either side of the back support 104 via support vertical plates, with a gap between them and the back support 104 surface. The stopper 2 slides within this gap, forming an L-shape with the support vertical plates. The frames 105, back support 104, stopper clips 103, and support vertical plates are integrally formed. The back support 104 comprises ten parallel slats, each connected to the frames 105 at both ends. The slats and the frames 105 are integrally formed. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. The bottom surface of the narrow end of the stopper 2 is integrally formed with a raised undercut 205, located outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the raised undercut 205 acts as a limit stop. When the raised undercut 205 abuts the frame 105, the stopper 2 reaches its limit position. The plastic frame body 1 is further provided with a hanging hole 106, which can be used to hang the plastic frame body 1. The rest is the same as in the first embodiment.

[0037] This dual-purpose plastic frame has two working gears, corresponding to the tight and loose states between the tool and the plastic frame. In scenarios such as when the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the workplace, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the wrench 3 is tightened by the second limiting part 201 and at the same time is pressed by the first limiting part The limiting part 201 is supported by the positioning part 101 to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, the user pushes the limiting part 2 according to the upper arrow and the "unclip" instruction until the edge of the limiting part 2 is in contact with the vertical step surface. At this time, the dual-purpose plastic frame is switched to another working gear. At this gear, when the wrench 3 is disengaged from the second limiting part 201 and is only limited by the first limiting part 101, the wrench 3 and the plastic frame are loosely fitted due to the fit between the wrench 3 and the first limiting part 101.

[0038] Example 3:

[0039] like Figures 1 to 4 As shown, a dual-purpose plastic frame is used to store a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a limiting member 2. The plastic frame body 1 is provided with a first limiting portion 101. The first limiting portions 101 are arranged in pairs, corresponding to twelve sizes of wrenches 3 with opening sizes ranging from 8 to 19 mm. The two first limiting portions 101 in each pair are located on both sides of the plastic frame body 1 and cooperate with the handle of the wrench 3. The first limiting portion 101 includes two groove walls, which form a tool embedding groove 109 with a small mouth and a large bottom, which can accommodate the handle of the wrench 3. The top of one of the groove walls is a hook-shaped structure, which blocks the handle of the wrench 3 embedded in the first limiting portion 101. When the wrench 3 is removed, the thinner part of the handle of the wrench 3 must be aligned with the groove of the first limiting portion 101 before it can be removed. The limiting member 2 is slidably connected to the plastic frame body 1, and a second limiting portion 201 is provided on the limiting member 2. The second limiting portion 201 can press the wrench 3 in the first limiting portion 101. Different from the embodiment 1, the third limiting portion 108 is further provided in the first limiting portion 101 in this embodiment. Figure 9As shown. The third limiting portion 108 has a smaller gap than the first limiting portion 101, which allows the tool to be clamped with the third limiting portion 108. Through a certain external force, the tool can be deviated from the third limiting portion 108 and cooperate with the surrounding first limiting portion 101. That is, the third limiting portion 108 allows the tool to have two different placement states: loose and tight within the embedded groove space of the first limiting portion 101. The plastic frame body 1 is trapezoidal, wide at one end and narrow at the other end. From the narrow end to the wide end, the specifications of the wrenches stored and arranged increase accordingly, that is, the closer to the wide end, the larger the size of the wrenches stored and arranged. The wide end of the plastic frame body 1 is provided with a handle portion 102. The handle portion 102 is integrally formed with the plastic frame body 1. The handle portion 102 is roughly a trapezoidal frame structure with a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface to improve the feel. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upper arrow and "unclip" indicate that the limit member 2 can be moved from the narrow end to the wide end of the plastic frame body 1 to release the cooperation between the second limit member 201 and the wrench 3, thereby achieving a loose fit between the wrench 3 and the dual-purpose plastic frame; the lower arrow and "clip" indicate that the limit member 2 can be moved from the wide end to the narrow end of the plastic frame body 1 to achieve a tight fit between the second limit member 201 and the wrench 3.

[0040] Correspondingly, the retaining member 2 is also designed to be roughly wide at one end and narrow at the other to better match the plastic frame body 1. However, there are equal-width sections at both the narrow end and the middle of the retaining member 2. Within these equal-width sections, the two sides of the retaining member 2 are parallel, ensuring that the retaining member 2 can slide in a straight line. The second retaining portion 201 is a resilient arched structure. The retaining member 2 is made of PET plastic and is integrally injection-molded with the retaining member 2. Two parallel, strip-shaped protrusions 203 are provided on the top of the second retaining portion 201. A shifting protrusion 204 is provided on the side of the retaining member 2. The plastic frame body 1 is provided with a shifting groove 110, which mates with the shifting protrusion 204 and forms a nested fit with the shifting protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a retaining plate 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms a lateral limit for the retaining member 2. The retaining member 2 slides within the area defined by the vertical step surface, the back support 104, and the retaining plate 103. When the edge of the retaining member 2 abuts the vertical step surface, the retaining member 2 reaches its limit of movement, leaving only the return degree of freedom. The retaining plate 103 is positioned on the frame 105 on both sides of the back support 104 via support plates, with a gap between the retaining plate 103 and the surface of the back support 104. The retaining member 2 slides within this gap. The retaining plate 103 and the support plates form an L-shape. The frame 105, back support 104, retaining plate 103, and the support plates are integrally formed. The back support 104 comprises eleven parallel slats, each connected to the frame 105 at both ends. The slats are integrally formed with the frame 105. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. A convex undercut 205 is integrally formed on the bottom surface of the narrow end of the stopper 2. This undercut 205 is positioned outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the undercut 205 acts as a limit stop. When the undercut 205 abuts the frame 105, the stopper 2 reaches its limit. The plastic frame body 1 also has a hanging hole 106, which can be used to hang the plastic frame body 1. The remainder of the embodiment is the same as in Example 1.

[0041] This dual-purpose plastic frame has two working gears, corresponding to the tight and loose states between the tool and the plastic frame. When the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the workplace, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the wrench 3 is tightened by the second limiting part 201 and at the same time is held in place by the first limiting part 101. Support, to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, push the limiter 2 according to the upper arrow and the "unclip" instruction until the edge of the limiter 2 is in contact with the vertical step surface. At this time, the dual-purpose plastic frame is switched to another working gear. In this gear, when the wrench 3 is disengaged from the second limiter 201 and is limited only by the first limiter 101, the wrench 3 is matched with the first limiter 101, thereby achieving a loose fit between the wrench 3 and the plastic frame; for specifications that are not used. After the wrench 3 is placed in the first limiter 101, it is twisted to a position where it is clamped with the third limiter 108 as the initial storage state of the tool. When in use, the wrench 3 of the specification needed for the current work is released from the clamping fit with the third limiter 108, and the specifications that are not used remain in their original state.

[0042] Example 4:

[0043] A dual-purpose plastic frame for storing a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a retaining member 2. The plastic frame body 1 is provided with a first retaining portion 101. The first retaining portions 101 are arranged in pairs, corresponding to twelve sizes of wrenches 3 with opening sizes ranging from 8 to 19 mm. The two first retaining portions 101 in each pair are located on either side of the plastic frame body 1 and cooperate with the handle of the wrench 3. The first retaining portion 101 includes two groove walls, which form a tool slot 109 with a small opening and a large bottom, allowing the handle of the wrench 3 to be inserted. The top of one of the groove walls is a hook-shaped structure, which blocks the handle of the wrench 3 inserted into the first retaining portion 101. This allows the wrench 3 to be removed by aligning the thinner portion of the handle of the wrench 3 with the slot of the first retaining portion 101. The limiting member 2 is slidably connected to the plastic frame body 1. The limiting member 2 is provided with a second limiting portion 201, which can tighten the wrench 3 within the first limiting portion 101. The plastic frame body 1 is trapezoidal in shape, wide at one end and narrow at the other. From the narrow end to the wide end, the size of the wrenches stored and arranged increases accordingly, i.e., the closer to the wide end, the larger the size of the wrenches stored and arranged. The wide end of the plastic frame body 1 is provided with a handle portion 102. The handle portion 102 is integrally formed with the plastic frame body 1 and has a roughly trapezoidal frame structure. It has a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface to improve the feel of the hand. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upper arrow and "unclip" indicate that the limit member 2 can be moved from the narrow end to the wide end of the plastic frame body 1 to release the cooperation between the second limit member 201 and the wrench 3, thereby achieving a loose fit between the wrench 3 and the dual-purpose plastic frame; the lower arrow and "clip" indicate that the limit member 2 can be moved from the wide end to the narrow end of the plastic frame body 1 to achieve a tight fit between the second limit member 201 and the wrench 3.

[0044] Correspondingly, the stopper 2 is also designed to be roughly wide at one end and narrow at the other to better match the plastic frame body 1. However, there are equal-width sections at both the narrow end and the middle of the stopper 2. Within these equal-width sections, the two sides of the stopper 2 are parallel, ensuring that the stopper 2 can slide in a straight line. Unlike Example 1, the second stopper 201 in this embodiment is a bow-shaped rubber member, bonded to the stopper 2. A shift protrusion 204 is provided on the side of the stopper 2, and a shift groove 110 is provided on the plastic frame body 1. The shift groove 110 matches the shift protrusion 204, forming a nested fit with the shift protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a retaining plate 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms a lateral limit for the retaining member 2. The retaining member 2 slides within the area defined by the vertical step surface, the back support 104, and the retaining plate 103. When the edge of the retaining member 2 abuts the vertical step surface, the retaining member 2 reaches its limit of movement, leaving only the return degree of freedom. The retaining plate 103 is positioned on the frame 105 on both sides of the back support 104 via support plates, with a gap between the retaining plate 103 and the surface of the back support 104. The retaining member 2 slides within this gap. The retaining plate 103 and the support plates form an L-shape. The frame 105, back support 104, retaining plate 103, and the support plates are integrally formed. The back support 104 comprises eight parallel slats, each connected to the frame 105 at both ends. The slats are integrally formed with the frame 105. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. A convex undercut 205 is integrally formed on the bottom surface of the narrow end of the stopper 2. This undercut 205 is positioned outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the undercut 205 acts as a limit stop. When the undercut 205 abuts the frame 105, the stopper 2 reaches its limit. The plastic frame body 1 also has a hanging hole 106, which can be used to hang the plastic frame body 1. The remainder of the embodiment is the same as in Example 1.

[0045] This dual-purpose plastic frame has two working gears, corresponding to the tight and loose states between the tool and the plastic frame. In scenarios such as when the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the workplace, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the wrench 3 is tightened by the second limiting part 201 and at the same time is pressed by the first limiting part The limiting part 201 is supported by the positioning part 101 to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, the user pushes the limiting part 2 according to the upper arrow and the "unclip" instruction until the edge of the limiting part 2 is in contact with the vertical step surface. At this time, the dual-purpose plastic frame is switched to another working gear. At this gear, when the wrench 3 is disengaged from the second limiting part 201 and is only limited by the first limiting part 101, the wrench 3 and the plastic frame are loosely fitted due to the fit between the wrench 3 and the first limiting part 101.

[0046] Example 5:

[0047] like Figure 10As shown, a dual-purpose plastic frame is used to store a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a limiting member 2. The plastic frame body 1 is provided with a first limiting portion 101. The first limiting portions 101 are arranged in pairs, corresponding to twelve sizes of wrenches 3 with opening sizes ranging from 8 to 19 mm. The two first limiting portions 101 in each pair are located on both sides of the plastic frame body 1 and cooperate with the handle of the wrench 3. The handle of the wrench 3 is provided with two positioning holes 301. Unlike Example 1, the first limiting portions 101 in this embodiment are limiting protrusions. The limiting protrusions are cylindrical, square, or hexagonal in shape. The limiting protrusions are inserted into the positioning holes 301 in a one-to-one manner to form a fit. In this embodiment, the limiting protrusions and the positioning holes 301 are clearance-fitted, so that the first limiting portions 101 can roughly position the wrench 3. The limiting member 2 is slidably connected to the plastic frame body 1. The limiting member 2 is provided with a second limiting portion 201. The second limiting portion 201 can limit the movement of the wrench 3 in the direction in which it can be detached from the plastic frame body 1. The second limiting portion 201 can be a clearance fit, so that the second limiting portion 201 and the first limiting portion 101 jointly limit the wrench 3 from detaching from the plastic frame body 1; or it can be an interference fit, so that the wrench 3 is tightly fitted to the plastic frame body 1 by the second limiting member 201 pressing against the wrench 3. The plastic frame body 1 is trapezoidal, with one end being wide and the other end being narrow. From the narrow end to the wide end, the size of the wrenches stored and arranged increases accordingly, that is, the closer to the wide end, the larger the size of the wrenches stored and arranged. The top surface of the plastic frame body 1 is provided with a washboard-shaped groove for accommodating the wrench 3. The wide end of the plastic frame body 1 is provided with a handle portion 102, which is integrally formed with the plastic frame body 1. The handle portion 102 has a roughly trapezoidal frame structure and a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface to improve the hand feel. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upward arrow and "unclip" indicate that moving the limit member 2 from the narrow end to the wide end of the plastic frame body 1 can release the fit between the second limit member 201 and the wrench 3, achieving a loose fit between the wrench 3 and the dual-purpose plastic frame. The downward arrow and "clip" indicate that moving the limit member 2 from the wide end to the narrow end of the plastic frame body 1 can achieve a tight fit between the second limit member 201 and the wrench 3.

[0048] Correspondingly, the stopper 2 is also designed to be generally wide at one end and narrow at the other to better match the plastic frame body 1. However, there are equal-width sections at both the narrow end and the middle of the stopper 2. Within these equal-width sections, the two sides of the stopper 2 are parallel, ensuring that the stopper 2 can slide in a straight line. Unlike Example 1, the second stopper 201 in this embodiment is an inverted L-shaped raised stopper that protrudes from the surface of the stopper 2 and stops the side edge of the tool within the first stopper 102. The stopper 2 is made of PET plastic, and the second stopper 201 and the stopper 2 are integrally injection molded. A shift protrusion 204 is provided on the side of the stopper 2, and a shift groove 110 is provided on the plastic frame body 1. The shift groove 110 matches the shift protrusion 204, forming a nested fit with the shift protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a retaining plate 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms a lateral limit for the retaining member 2. The retaining member 2 slides within the area defined by the vertical step surface, the back support 104, and the retaining plate 103. When the edge of the retaining member 2 abuts the vertical step surface, the retaining member 2 reaches its limit of movement, leaving only the return degree of freedom. The retaining plate 103 is positioned on the frame 105 on both sides of the back support 104 via support plates, with a gap between the retaining plate 103 and the surface of the back support 104. The retaining member 2 slides within this gap. The retaining plate 103 and the support plates form an L-shape. The frame 105, back support 104, retaining plate 103, and the support plates are integrally formed. The back support 104 comprises eleven parallel slats, each connected to the frame 105 at both ends. The slats are integrally formed with the frame 105. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. A convex undercut 205 is integrally formed on the bottom surface of the narrow end of the stopper 2. This undercut 205 is positioned outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the undercut 205 acts as a limit stop. When the undercut 205 abuts the frame 105, the stopper 2 reaches its limit. The plastic frame body 1 also has a hanging hole 106, which can be used to hang the plastic frame body 1. The remainder of the embodiment is the same as in Example 1.

[0049] This dual-purpose plastic frame has two working gears, corresponding to the tight and loose states between the tool and the plastic frame. When the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the work site, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the side edge of the handle of the wrench 3 is tightened by the second limiting part 201, and at the same time, it is pressed by the second limiting part 201. A limit part 101 supports it to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, he pushes the limit part 2 according to the upper arrow and the "unclip" instruction until the edge of the limit part 2 is in contact with the vertical step surface. At this time, the dual-purpose plastic frame is switched to another working gear. At this gear, when the wrench 3 is disengaged from the second limit part 201 and is only limited by the first limit part 101, the wrench 3 and the plastic frame are loosely fitted because they are matched.

[0050] Example 6:

[0051] like Figure 11As shown, a dual-purpose plastic frame is used to store a set of open-end wrenches. The dual-purpose plastic frame includes a plastic frame body 1 and a limiting member 2. The plastic frame body 1 is provided with a first limiting portion 101. The first limiting portions 101 are arranged in pairs, corresponding to twelve sizes of wrenches 3 with opening sizes of 8-19 mm. The two first limiting portions 101 in each pair are respectively located on both sides of the plastic frame body 1 and cooperate with the handle of the wrench 3. The first limiting portion 101 is a limiting protrusion, which is cylindrical, square, or hexagonal. Unlike Example 5, the limiting protrusions in this embodiment are inserted into the wrench opening and the tail end ring of the wrench 3 in a one-to-one correspondence, and the limiting protrusions are preferably clearance-fitted with the wrench opening and the tail end ring. In this way, the first limiting portion 101 can roughly position the wrench 3. The limiting member 2 is slidably connected to the plastic frame body 1. The limiting member 2 is provided with a second limiting portion 201, and the second limiting portion 201 can tighten the wrench 3 in the first limiting portion 101. The plastic frame body 1 is trapezoidal in shape, with one end being wide and the other end being narrow. From the narrow end to the wide end, the specifications of the wrenches stored and arranged increase accordingly, that is, the closer to the wide end, the larger the size of the wrenches stored and arranged. The top surface of the plastic frame body 1 is provided with a washboard-shaped groove for placing the wrench 3. The wide end of the plastic frame body 1 is provided with a handle portion 102. The handle portion 102 is integrally formed with the plastic frame body 1. The handle portion 102 is roughly a trapezoidal frame structure, with a handle opening 107 that can accommodate four fingers of the hand. The inner wall of the handle opening 107 has a curved surface that can improve the feel. The handle portion 102 is marked with an arrow indicating the movement direction of the limit member 2 and the indicators "clip" and "unclip". The upper arrow and "unclip" indicate that the limit member 2 can be moved from the narrow end to the wide end of the plastic frame body 1 to release the cooperation between the second limit member 201 and the wrench 3, thereby achieving a loose fit between the wrench 3 and the dual-purpose plastic frame; the lower arrow and "clip" indicate that the limit member 2 can be moved from the wide end to the narrow end of the plastic frame body 1 to achieve a tight fit between the second limit member 201 and the wrench 3.

[0052] Correspondingly, the stopper 2 is also designed to be roughly wide at one end and narrow at the other to better match the plastic frame body 1. However, there are equal-width sections at both the narrow end and the middle of the stopper 2. Within these equal-width sections, the two sides of the stopper 2 are parallel, ensuring that the stopper 2 can slide in a straight line. The second stopper 201 is an inverted L-shaped raised stopper that protrudes from the surface of the stopper 2 and stops the side edge of the tool within the first stopper 102. The stopper 2 is made of PET plastic and is integrally injection-molded with the second stopper 201. A shift protrusion 204 is provided on the side of the stopper 2, and a shift groove 110 is provided on the plastic frame body 1. The shift groove 110 mates with the shift protrusion 204, forming a nested fit with the shift protrusion 204. The plastic frame body 1 comprises a frame 105, a back support 104, and a retaining plate 103. A step is provided between the frame 105 and the back support 104. The vertical step surface of the step forms a lateral limit for the retaining member 2. The retaining member 2 slides within the area defined by the vertical step surface, the back support 104, and the retaining plate 103. When the edge of the retaining member 2 abuts the vertical step surface, the retaining member 2 reaches its limit of movement, leaving only the return degree of freedom. The retaining plate 103 is positioned on the frame 105 on both sides of the back support 104 via support plates, with a gap between the retaining plate 103 and the surface of the back support 104. The retaining member 2 slides within this gap. The retaining plate 103 and the support plates form an L-shape. The frame 105, back support 104, retaining plate 103, and the support plates are integrally formed. The back support 104 comprises eleven parallel slats, each connected to the frame 105 at both ends. The slats are integrally formed with the frame 105. The narrow end of the stopper 2 extends beyond the narrow end of the plastic frame body 1. A convex undercut 205 is integrally formed on the bottom surface of the narrow end of the stopper 2. This undercut 205 is positioned outside the frame 105. As the stopper 2 slides from the narrow end to the wide end of the plastic frame body 1, the undercut 205 acts as a limit stop. When the undercut 205 abuts the frame 105, the stopper 2 reaches its limit. The plastic frame body 1 also has a hanging hole 106, which can be used to hang the plastic frame body 1. The remainder of the embodiment is the same as in Example 1.

When the wrench 3 is hung up for display and sale as a set, or when the user takes the whole set of tools to the work site, the limiter 2 is pushed according to the instructions of the lower arrow and "clip" until the gear protrusion 204 is engaged with the gear groove 110, and the dual-purpose plastic frame is switched to a working gear. At this time, the protrusion buckle 205 also presses against the frame 105, and the second limiting part 201 reaches the position of the wrench 3. Under the multi-directional constraints of the first limiting part 101 and the second limiting part 201, the side edge of the handle of the wrench 3 is tightened by the second limiting part 201, and at the same time, it is pressed by the second limiting part 201. A limit part 101 supports it to achieve a tight fit with the plastic frame; when the user places the entire set of tools on a work surface or the ground at the work site, he pushes the limit part 2 according to the upper arrow and the "unclip" instruction until the edge of the limit part 2 is in contact with the vertical step surface.
