Description

Technical Field

[0001] This utility model relates to the technical field of ceiling screw installation tools, specifically to a rod positioning and leveling device. Background Technology

[0002] In building decoration and renovation projects, the ceiling is a type of decoration on the top of the living environment and an important part of the interior decoration. The ceiling has the effects of heat insulation, heat insulation, sound insulation and sound absorption. At the same time, it is also a concealed layer for electrical, ventilation and air conditioning projects, playing an important role in concealing mechanical and electrical pipelines and improving the overall living comfort and aesthetics of the house. The ceiling uses ceiling screws as a support frame and ceiling bolts to fix the ceiling keel. Adjusting the level of the keel, and thus the level of the ceiling.

[0003] Traditional ceiling rod height adjustment involves using a laser level to project a horizontal reference plane, measuring the distance from the bottom of each ceiling rod to the laser line with a tape measure, and then adjusting the height by rotating the adjusting nut on the ceiling rod. This method is labor-intensive and inefficient because if the ceiling bolts are not on the same horizontal plane, operators must repeatedly climb to higher positions to adjust them. Furthermore, because the ceiling bolts are not perfectly vertical during pre-installation, they may not be on the same horizontal plane during measurement. However, during keel installation, the weight of the keel can cause the ceiling bolts to shift, resulting in the keel not being on the same horizontal plane and compromising the structural safety of the ceiling. Summary of the Invention

[0004] The purpose of this utility model is to provide a suspension rod positioning and leveling device to solve the structural safety problems of low construction efficiency caused by operators having to repeatedly climb to heights and keel position displacement caused by insufficient installation accuracy of ceiling suspension rods in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A suspension rod positioning and leveling device, characterized in that it comprises: a first connecting rod and a first sleeve, the first sleeve being installed at one end of the first connecting rod, the first connecting rod being capable of driving the first sleeve to rotate; a ceiling bolt and a ceiling threaded rod, the ceiling bolt being screwed onto the ceiling threaded rod; the first sleeve being sleeved on the ceiling bolt, and the first sleeve being adapted to the ceiling bolt, the first sleeve being capable of driving the ceiling bolt to rotate, so that the ceiling bolt moves along the length direction of the ceiling threaded rod; a limiting member being formed at the top of the first sleeve, the limiting member being used to suspend the first sleeve on the ceiling bolt; a laser emitter, the laser emitter being installed on the first connecting rod, the laser emitter being capable of emitting a laser surface perpendicular to the first connecting rod; and a level, the level being installed at the other end of the first connecting rod, and the level being capable of detecting the horizontal state of the laser surface.

[0007] Based on the above-mentioned technical means, operators can adjust the height of the ceiling bolts by rotating the first connecting rod, avoiding the need for operators to repeatedly climb to high places to adjust the height of the ceiling bolts, thus improving construction efficiency. Furthermore, operators can adjust the height of the ceiling bolts directly on the ground, preventing safety issues caused by falls from heights and increasing the safety of operators during the construction process.

[0008] This invention incorporates a limiting component and a laser emitter. The limiting component allows the first sleeve to be suspended from the ceiling bolt. When the first sleeve is suspended, the laser emitter stably emits a laser surface perpendicular to the first connecting rod, reducing inaccurate measurements caused by laser surface instability due to the shaking of the first connecting rod and improving the accuracy of the measurement process. Simultaneously, by comparing the laser surface emitted by the laser emitter with a pre-set reference line to obtain the position and height of the ceiling bolt, the position of the ceiling bolt can be quickly adjusted according to the positional relationship between the laser surface and the pre-set reference line, so that the laser surface is aligned with the pre-set reference line, thereby improving measurement accuracy and work efficiency.

[0009] This invention features a level at the end of the first connecting rod. The level detects whether the laser surface is horizontal, preventing inaccurate height determination due to the tilting of the ceiling bolts. Specifically, according to construction requirements, the ceiling bolts should be installed horizontally, ensuring the first connecting rod is parallel to the bolts during use (i.e., the first connecting rod is vertically positioned). The laser emitted by the laser emitter on the first connecting rod should be horizontal, and the level should display a horizontal reading. However, when the ceiling bolts tilt, the first connecting rod tilts accordingly, causing the laser emitted by the laser emitter on the first connecting rod to deviate from the horizontal plane. In this case, the level will show a non-horizontal reading, requiring adjustment of the ceiling bolts via the first connecting rod until the level displays a horizontal reading. Then, by checking whether the test line projected onto the wall (or other standard object) by the laser surface aligns with the preset baseline, the height of the ceiling bolts can be determined to be acceptable.

[0010] Furthermore, a first groove is formed inside the first sleeve, which can tightly abut against the ceiling bolt, so that the first sleeve can drive the ceiling bolt to rotate.

[0011] According to the above-mentioned technical means, the first groove can tightly abut against the ceiling bolt, making the contact between the first sleeve and the ceiling bolt more compact. When the first sleeve rotates, it can drive the ceiling bolt to rotate stably, thereby realizing the precise movement of the ceiling bolt along the ceiling screw, avoiding inaccurate adjustment or shaking caused by loosening, and improving adjustment accuracy and stability. Since the first sleeve can tightly drive the ceiling bolt to rotate, the operator can directly adjust the height of the ceiling bolt by rotating the first connecting rod without manually tightening the bolt, reducing operation steps. Moreover, the tight fit between the first groove and the ceiling bolt also reduces repeated adjustments caused by loosening or slipping of the ceiling bolt, ensuring that the expected effect can be achieved with one adjustment, thus improving construction efficiency.

[0012] Furthermore, a second groove is formed inside the first sleeve, the second groove is connected to the first groove, and the second groove penetrates the bottom of the first sleeve along the axial direction of the first sleeve; the ceiling bolt can pass through the second groove to reach the first groove.

[0013] Based on the aforementioned technical means, the design of the second groove provides more space for the insertion and movement of the ceiling bolt, making the installation process smoother. Operators can easily pass the ceiling bolt through the second groove into the first groove to achieve a tight fit. During the adjustment process, the presence of the second groove also allows the ceiling bolt to slide more freely when moving, reducing jamming or resistance caused by space limitations and further improving adjustment efficiency.

[0014] Furthermore, the limiting member is a limiting plate, and a through hole is formed on the limiting plate. The through hole is connected to the first groove and is used to pass through the ceiling screw.

[0015] Based on the above technical means, the design of the limiting component allows the first sleeve to be stably suspended on the ceiling bolt. The ceiling screw can pass through the through hole on the limiting plate, so that the first sleeve always maintains a connection with the ceiling screw during the adjustment process, avoiding the risk of the first sleeve accidentally falling off during operation.

[0016] Furthermore, an opening is formed on the side wall of the first sleeve, the opening is arranged along the axial direction of the first sleeve, and the opening is connected to the first groove, the second groove and the through hole; the opening is used to pass through the ceiling screw.

[0017] According to the above technical means, by setting an opening, the ceiling screw can pass through the opening and enter the second groove, and the ceiling bolt can enter the second groove, and then enter the first groove through the second groove, so as to suspend the first sleeve on the ceiling bolt.

[0018] Furthermore, the first connecting rod includes a first support rod and a second support rod, the second support rod is sleeved on the first support rod, and the first support rod can move within the second support rod along its length; the first support rod is connected to the first sleeve, and the second support rod is connected to the level.

[0019] According to the above-mentioned technical means, the first connecting rod consists of a first support rod and a second support rod, and the first support rod can move within the second support rod, so that the length of the first connecting rod can be adjusted according to actual needs, thereby adapting to the installation requirements of ceilings of different heights and improving the versatility and applicability of the device; the first connecting rod includes a first support rod and a second support rod, so that the length of the first connecting rod can be adjusted according to actual operation needs, and operators do not need to replace the first connecting rod of different lengths, reducing operation steps and time, and improving construction efficiency.

[0020] Furthermore, the first connecting rod also includes a limiting bolt. The first support rod and the second support rod are respectively provided with a first limiting hole and a second limiting hole. The limiting bolt can pass through the first limiting hole and the second limiting hole to fix the first support rod on the second support rod.

[0021] According to the above technical means, the limiting bolt fixes the first support rod and the second support rod together, preventing the first connecting rod from expanding or contracting due to external force or vibration during use. This effectively prevents adjustment failure or safety hazards caused by loosening of the first connecting rod, increases the stability of the first connecting rod during adjustment and use, and reduces mechanical wear caused by frequent expansion and contraction. By fixing the first support rod to the second support rod, the first connecting rod is more stable during use, reducing damage caused by vibration or external force, extending the service life of the device, and reducing maintenance costs.

[0022] Furthermore, there are multiple first limiting holes, which are evenly distributed along the length of the first support rod; there are also multiple second limiting holes, which are evenly distributed along the length of the second support rod.

[0023] Based on the aforementioned technical means, by setting multiple first limiting holes on the first support rod and multiple second limiting holes on the second support rod, the operator can select different limiting holes for fixing as needed, thereby achieving more precise length adjustment. This makes the length adjustment of the first connecting rod more flexible, allowing for adjustments in smaller increments and increasing the accuracy of the adjustment process. The design of multiple first and multiple second limiting holes not only improves adjustment accuracy and flexibility but also reduces mechanical wear caused by frequent adjustments, enhancing the durability and reliability of the first and second support rods, extending the service life of the device, and reducing maintenance costs.

[0024] Furthermore, it also includes a hinge, through which the level is rotatably mounted on the first connecting rod.

[0025] According to the above-mentioned technical means, the level can rotate relative to the first connecting rod through the hinge, so that the level can adjust the angle according to actual needs, thereby better adapting to different construction environments and operational requirements. In actual construction, operators may need to observe the reading of the level from different angles, especially in complex spatial environments, such as in places with obstacles or limited space, so that the level can flexibly adjust the angle, making it convenient for operators to make accurate level measurements.

[0026] Furthermore, the hinge includes a second sleeve and a second connecting rod, the second sleeve being fixed to the side wall of the first connecting rod; the second connecting rod is rotatably installed inside the second sleeve, and the second connecting rod is connected to the level, so that the level is rotatably installed on the first connecting rod.

[0027] Based on the aforementioned technical means, through the combined design of the second sleeve and the second connecting rod, the level can be stably mounted on the first connecting rod and can rotate around the axis of the second sleeve, providing a reliable support point for the level and ensuring that it will not loosen or wobble during rotation. The structural design of the second sleeve and the second connecting rod can withstand frequent rotation operations, reducing failures caused by mechanical wear, improving the durability of the second sleeve and the second support rod, and extending their service life.

[0028] The beneficial effects of this utility model are:

[0029] 1. Operators can adjust the height of the ceiling bolts by rotating the first connecting rod, avoiding the need for operators to repeatedly climb to high places to adjust the height of the ceiling bolts, thus improving construction efficiency. In addition, operators can adjust the height of the ceiling bolts directly on the ground, preventing safety issues caused by falls from heights and increasing the safety of operators during the construction process.

[0030] 2. This utility model, by setting a limiting component and a laser emitter, allows the first sleeve to be suspended on the ceiling bolt. When the first sleeve is suspended on the ceiling bolt, the laser emitter can stably emit a laser surface perpendicular to the first connecting rod, reducing the instability of the laser surface caused by the shaking of the first connecting rod and thus improving the accuracy of the measurement process. At the same time, by comparing the laser surface emitted by the laser emitter with a pre-set reference line to obtain the position height of the ceiling bolt, the position of the ceiling bolt can be quickly adjusted according to the positional relationship between the laser surface and the pre-set reference line, so that the laser surface is aligned with the pre-set reference line, thereby improving measurement accuracy and work efficiency.

[0031] 3. This utility model includes a level at the end of the first connecting rod. The level detects whether the laser surface is horizontal, preventing the ceiling bolts from tilting and causing the laser surface to tilt, which would lead to inaccurate height determination. Specifically, according to construction requirements, the ceiling bolts should be installed horizontally, ensuring the first connecting rod is parallel to the bolts during use (i.e., the first connecting rod is vertically installed). The laser surface emitted by the laser emitter on the first connecting rod should be horizontal, and the level should display a horizontal reading. However, when the ceiling bolts tilt, the first connecting rod tilts accordingly, causing the laser surface emitted by the laser emitter on the first connecting rod to deviate from the horizontal plane. In this case, the level should display a non-horizontal reading, requiring adjustment of the ceiling bolts via the first connecting rod until the level displays a horizontal reading. Then, by checking whether the test line projected onto the wall (or other standard object) by the laser surface aligns with the preset baseline, the height of the ceiling bolts can be determined to be acceptable.

[0040] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0041] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0042] like Figure 1 and Figure 2As shown in the figure, this embodiment proposes a rod positioning and leveling device, including: a first connecting rod 1 and a first sleeve 2, the first sleeve 2 is installed at one end of the first connecting rod 1, and the first connecting rod 1 can drive the first sleeve 2 to rotate; a ceiling bolt (not shown in the figure) and a ceiling threaded rod (not shown in the figure), the ceiling bolt is screwed onto the ceiling threaded rod; the first sleeve 2 is used to be sleeved on the ceiling bolt, and the first sleeve 2 is adapted to the ceiling bolt, the first sleeve 2 can drive the ceiling bolt to rotate, so that the ceiling bolt moves along the length direction of the ceiling threaded rod; a limiting member 21 is formed at the top of the first sleeve 2, the limiting member 21 is used to suspend the first sleeve 2 on the ceiling bolt; a laser emitter 3, the laser emitter 3 is installed on the first connecting rod 1, the laser emitter 3 can emit a laser surface perpendicular to the first connecting rod 1; a level 4, the level 4 is installed at the other end of the first connecting rod 1, and the level 4 can detect the horizontal state of the laser surface.

[0043] like Figure 1 and Figure 2 As shown, the usage process of this embodiment is as follows: First, the first sleeve 2, laser emitter 3, and level 4 are installed on the first connecting rod 1. During use, the first connecting rod 1 rotates, causing the first sleeve 2 to rotate. The first sleeve 2 drives the ceiling bolt to rotate, so that the ceiling bolt moves along the length of the ceiling screw. The first sleeve 2 is suspended on the ceiling bolt by the limiting member 21. The laser emitter 3 emits a laser surface perpendicular to the first connecting rod 1, so that the laser surface is aligned with the preset reference line (the reference line is the preset height of the ceiling bolt and the height reference line of the first connecting rod 1). Then, the level 4 is kept horizontal. At this time, the laser surface is kept horizontal. Since the laser surface is perpendicular to the first connecting rod 1, the first connecting rod 1 is perpendicular to the horizontal plane. Thus, the ceiling bolt, the ceiling bolt, and the first sleeve 2 are all set perpendicular to the horizontal plane. The above operation is repeated to adjust multiple ceiling bolts to the same height and multiple ceiling screws to be set perpendicular to the horizontal plane.

[0044] Operators can adjust the height of the ceiling bolts by rotating the first connecting rod 1, which avoids the need for operators to repeatedly climb to high places to adjust the height of the ceiling bolts, improves construction efficiency, and allows operators to adjust the height of the ceiling bolts directly on the ground, preventing safety issues caused by falls from heights and increasing the safety of operators during construction.

[0045] In this embodiment, by setting a limiting component 21 and a laser emitter 3, the first sleeve 2 can be suspended on the ceiling bolt. When the first sleeve 2 can be suspended on the ceiling bolt, the laser emitter 3 can stably emit a laser surface perpendicular to the first connecting rod 1, which reduces the instability of the laser surface caused by the shaking of the first connecting rod 1 and thus improves the accuracy of the measurement process. At the same time, the laser surface emitted by the laser emitter 3 is compared with a pre-set reference line to obtain the position height of the ceiling bolt. The position of the ceiling bolt can be quickly adjusted according to the positional relationship between the laser surface and the pre-set reference line so that the laser surface is aligned with the pre-set reference line, thereby improving the measurement accuracy and work efficiency.

[0046] This embodiment also includes a level 4. By adjusting the first connecting rod 1, the level 4 is kept horizontal. At this time, the laser surface is kept horizontal, and since the laser surface is perpendicular to the first connecting rod 1, the first connecting rod 1 is perpendicular to the horizontal plane. This ensures that the ceiling bolt, the ceiling screw, and the first sleeve 2 are all set perpendicular to the horizontal plane. In other words, the level 4 can obtain the horizontal state of the ceiling screw. The operator can adjust the ceiling screw according to the horizontal state of the level 4 so that the ceiling screw is perpendicular to the horizontal plane, preventing the ceiling screw from shifting position during the installation of the ceiling and increasing the safety of the installation process.

[0047] like Figure 3 As shown, in this embodiment, a first groove 22 is formed inside the first sleeve 2. The first groove 22 can be tightly abutted against the ceiling bolt so that the first sleeve 2 can drive the ceiling bolt to rotate.

[0048] The first groove 22 can tightly abut against the ceiling bolt, making the contact between the first sleeve 2 and the ceiling bolt more compact. This ensures that the first sleeve 2 can drive the ceiling bolt to rotate stably when rotating, thereby achieving precise movement of the ceiling bolt along the ceiling screw. This avoids inaccurate adjustment or shaking caused by loosening, improving adjustment accuracy and stability. Since the first sleeve 2 can tightly drive the ceiling bolt to rotate, the operator can directly adjust the height of the ceiling bolt by rotating the first connecting rod 1 without manually tightening the bolt, reducing operation steps. Furthermore, the tight fit between the first groove 22 and the ceiling bolt also reduces repeated adjustments caused by loosening or slipping of the ceiling bolt, ensuring that the expected effect can be achieved with a single adjustment, thus improving construction efficiency.

[0049] like Figure 3As shown, in this embodiment, a second groove 23 is formed inside the first sleeve 2. The second groove 23 is connected to the first groove 22, and the second groove 23 extends through the bottom of the first sleeve 2 along its axial direction. The ceiling bolt can pass through the second groove 23 to reach the first groove 22. The design of the second groove 23 provides more space for the insertion and movement of the ceiling bolt, making the installation process smoother. The operator can easily insert the ceiling bolt through the second groove 23 into the first groove 22 to achieve a tight fit. During adjustment, the presence of the second groove 23 also allows the ceiling bolt to slide more freely when moving, reducing jamming or resistance caused by space limitations. This embodiment improves adjustment efficiency.

[0050] like Figure 3 As shown, in this embodiment, when the laser surface and the reference line are not on the same plane, the first sleeve 2 can be moved so that the ceiling bolt enters the second groove 23 from the first groove 22. At this time, the first sleeve 2 is rotated so that the laser surface and the reference line are on the same plane. Then the first sleeve 2 is moved again so that the ceiling bolt enters the first groove 22 from the second groove 23. The limiting member 21 suspends the first sleeve 2 on the ceiling bolt to obtain the positional relationship between the laser surface and the reference line and then adjust the position of the ceiling bolt so that the laser surface is aligned with the reference line.

[0051] like Figure 3 As shown, in this embodiment, the limiting member 21 is a limiting plate with a through hole 211. The through hole 211 is connected to the first groove 22 and is used for the ceiling screw to pass through. The design of the limiting member 21 allows the first sleeve 2 to be stably suspended on the ceiling screw. Through the through hole 211 on the limiting plate, the ceiling screw can pass through the through hole 211, ensuring that the first sleeve 2 remains connected to the ceiling screw during adjustment and avoiding the risk of the first sleeve 2 accidentally falling off during operation.

[0052] like Figure 3 As shown, the diameter of the through hole 211 is larger than the diameter of the ceiling screw and smaller than the diameter of the ceiling bolt. The ceiling screw can pass through the through hole 211, but the ceiling bolt cannot pass through the through hole 211, so that the first sleeve 2 can be suspended on the ceiling bolt by the limiting member 21.

[0053] like Figure 3 As shown, in this embodiment, an opening 24 is formed on the side wall of the first sleeve 2. The opening 24 is arranged along the axial direction of the first sleeve 2 and is connected to the first groove 22, the second groove 23, and the through hole 211. The opening 24 is used for the ceiling bolt to pass through. By providing the opening 24, the ceiling bolt can pass through the opening 24 and enter the second groove 23, and the ceiling bolt can enter the second groove 23, and then enter the first groove 22 through the second groove 23, so as to suspend the first sleeve 2 on the ceiling bolt.

[0054] like Figure 3 As shown, the width of the opening 24 is greater than the diameter of the ceiling screw and less than the diameter of the ceiling bolt. The ceiling screw can pass through the opening 24, but the ceiling bolt cannot pass through the opening 24, which prevents the ceiling bolt from moving out of the first sleeve 2 from the opening 24 and causing safety problems. This ensures that the ceiling bolt can only enter or leave the first sleeve 2 from the second groove 23.

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, the first connecting rod 1 includes a first support rod 11 and a second support rod 12. The second support rod 12 is sleeved on the first support rod 11, and the first support rod 11 can move within the second support rod 12 along the length direction. The first support rod 11 is connected to the first sleeve 2, and the second support rod 12 is connected to the level 4.

[0056] The first connecting rod 1 consists of a first support rod 11 and a second support rod 12, and the first support rod 11 can move within the second support rod 12, so that the length of the first connecting rod 1 can be adjusted according to actual needs, thereby adapting to the installation requirements of ceilings of different heights and improving the versatility and applicability of the device; the first connecting rod 1 includes a first support rod 11 and a second support rod 12, so that the length of the first connecting rod 1 can be adjusted according to actual operation requirements, and the operator does not need to replace the first connecting rod 1 of different lengths, reducing operation steps and time, and improving construction efficiency.

[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the first connecting rod 1 further includes a limiting bolt 13. The first support rod 11 and the second support rod 12 are respectively provided with a first limiting hole 111 and a second limiting hole 121. The limiting bolt 13 can pass through the first limiting hole 111 and the second limiting hole 121 to fix the first support rod 11 on the second support rod 12.

[0058] The limiting bolt 13 fixes the first support rod 11 and the second support rod 12 together, preventing the first connecting rod 1 from expanding or contracting due to external force or vibration during use. This effectively prevents adjustment failures or safety hazards caused by the loosening of the first connecting rod 1, increases the stability of the first connecting rod 1 during adjustment and use, and reduces mechanical wear caused by frequent expansion and contraction. By fixing the first support rod 11 to the second support rod 12, the first connecting rod 1 is more stable during use, reduces damage caused by vibration or external force, extends the service life of the device, and reduces maintenance costs.

[0059] In this preferred embodiment, the number of limiting bolts 13 is multiple, which increases the connection stability of the first support rod 11 and the second support rod 12.

[0060] like Figure 1As shown, in this embodiment, there are multiple first limiting holes 111, which are evenly distributed along the length of the first support rod 11; there are multiple second limiting holes 121, which are evenly distributed along the length of the second support rod 12.

[0061] By setting multiple first limiting holes 111 on the first support rod 11 and multiple second limiting holes 121 on the second support rod 12, the operator can select different first limiting holes 111 and second limiting holes 121 for fixing as needed, thereby achieving more precise length adjustment. This makes the length adjustment of the first connecting rod 1 more flexible, allowing for adjustments in smaller increments and increasing the accuracy of the adjustment process. The design of multiple first limiting holes 111 and multiple second limiting holes 121 not only improves the adjustment accuracy and flexibility but also reduces mechanical wear caused by frequent adjustments, enhancing the durability and reliability of the first connecting rod 1, extending its service life, and reducing maintenance costs.

[0062] like Figure 1 and Figure 4 As shown, in this embodiment, a hinge 5 is also included, and the level 4 is rotatably mounted on the first connecting rod 1 via the hinge 5.

[0063] The level 4 can rotate relative to the first connecting rod 1 via the hinge 5, allowing the level 4 to adjust its angle according to actual needs. This better adapts to different construction environments and operational requirements. In actual construction, operators may need to observe the readings of the level 4 from different angles, especially in complex spatial environments, such as in places with obstacles or limited space. The hinge design allows the level 4 to be flexibly adjusted, facilitating accurate level measurements by the operator.

[0064] like Figure 1 and Figure 4 As shown, in this embodiment, the hinge 5 includes a second sleeve 51 and a second connecting rod 52. The second sleeve 51 is fixed on the side wall of the first connecting rod 1. The second connecting rod 52 is rotatably installed inside the second sleeve 51 and is connected to the level 4 so that the level 4 is rotatably installed on the first connecting rod 1.

[0065] Through the combined design of the second sleeve 51 and the second connecting rod 52, the level 4 can be stably mounted on the first connecting rod 1 and can rotate around the axis of the second sleeve 51, providing a reliable support point for the level 4 and ensuring that it will not loosen or wobble during rotation. The structural design of the second sleeve 51 and the second connecting rod 52 can withstand frequent rotation operations, reduce failures caused by mechanical wear, improve the durability of the second sleeve 51 and the second support rod 12, and extend their service life.

[0066] Example 2

[0067] This embodiment is similar to Embodiment 1, and the same parts are described in Embodiment 1. The following description only focuses on the improved parts.

[0068] like Figure 4 As shown in the figure, in this embodiment, a collar (not shown) is formed on the level 4. The collar is used to fit onto the second connecting rod 52, allowing the level 4 to rotate relative to the first connecting rod 1. By setting the collar, wear caused by rotation between the hinge 5 and the level 4 can be reduced, extending the service life of the level 4 and the hinge 5, thereby reducing costs.

[0069] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
