Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and more specifically, to a wrench specifically for suspension rods. Background Technology

[0002] A wrench is a common tool widely used in mechanical repair, construction, and automotive repair to tighten or loosen bolts, nuts, and other fasteners. Hanging rods are metal components used in construction to fix structural members (such as floor slabs and beams), typically connected to bolts via nuts. Wrenches used for hanging rods need to meet the following characteristics: high strength to prevent damage during tightening; a suitable opening size to tightly fit the hexagonal face of the bolt or nut to prevent slippage; and ease of operation, suitable for working at heights or in confined spaces, with a handle of appropriate length for easy application of force.

[0003] Chinese Patent Application Document 1 (Application No.: 2020104893788, Application Date: 2020.06.02) discloses a remote viewing device for a wrench, comprising: a probe assembly for monitoring nuts, a display assembly, and a connecting assembly; the probe assembly includes: a probe holder 50' and an endoscope lens 51' disposed within the probe holder 50'; the display assembly includes: a display 52' and a display bracket 53' for fixing the display 52'; the connecting assembly includes: a first insulating tube 54', a connecting wire 55' disposed within the first insulating tube 54', a first connector 56', and a second connector 57'. This application also discloses an adjusting wrench, which includes a remote viewing device for a wrench, and further includes: a crank assembly 10', a transmission mechanism 20' connected to the crank assembly 10', a positioning mechanism 30', and an insulating mechanism 40'. The aforementioned device requires the first insulating tube 54' to be held by hand, which limits the fixing force of the device and makes it difficult to apply force to rotate the crank assembly 10'. Furthermore, the combination of the crank assembly 10' and the first insulating tube 54' in the above scheme cannot apply a strong tightening force, limiting its application scenarios. At the same time, the device is heavy and cannot be used by hand for a long time.

[0004] Chinese Patent Application Document 2 (Application No.: 2024107078208, Application Date: 2024.06.03) discloses a self-locking variable diameter socket wrench, belonging to the technical field of socket wrenches. Through a clamping mechanism and a transmission mechanism, the operator can grip the handle and directly place the socket onto the bolt surface. Then, by rotating a second shaft with their fingers, the second shaft drives a first gear through a second gear. The first gear drives three adjusting grooves on the surface to rotate synchronously and pushes a connecting shaft to move. The connecting shaft can drive the jaws and movable parts to move horizontally under the constraint of a limit rail, ensuring that the three jaws are engaged with the bolt surface. However, this solution has a relatively short torque and cannot be used for high-altitude work or operations at heights. Furthermore, this solution must be used perpendicular to the nut and cannot be used parallel to it.

[0005] Chinese Patent Application Document 3 (Application No.: 2019207683356, Application Date: 2019.05.17) discloses an electric wrench with an adjustable lighting device, including a rear wrench housing, a front wrench housing, a toggle head, and a button. The right side wall of the rear wrench housing is connected to the front wrench housing, and the front and rear wrench housings are integrally formed. A button is fixedly connected to the top center of the rear wrench housing. A toggle head is installed at the right end of the front wrench housing and passes through the front wrench housing. The rear wrench housing includes a battery pack and a motor. The battery pack is fixedly connected to the left side of the inner cavity of the rear wrench housing, and the motor is fixedly connected to the right side of the inner cavity of the rear wrench housing via a fixing rod. The button is electrically connected to the battery pack and the motor. A rotating shaft is threadedly connected to the right side wall of the motor. A first bevel gear is fixedly connected to the right end of the rotating shaft. A second bevel gear is sleeved in the middle section of the toggle head. The first and second bevel gears are rotatably connected. A groove is provided in the front wrench housing, and a fixing rod is mounted in the groove. At least one lighting device connected to the battery pack is rotatably sleeved on the fixing rod. The aforementioned solution is heavy and inconvenient to handle, and also suffers from the problems present in Chinese patent applications 1 and 2.

When the transmission rod is rotated, it directly engages and acts with the nuts on the suspension rods. Compared with chain drive, the transmission efficiency is high, and less force can be applied to tighten the nuts on the suspension rods under the same tightening requirements. At the same time, the fastening part provided by this utility model makes direct and complete contact with the nuts on the suspension rods. The fastening part has high transmission efficiency between the nuts on the suspension rods and the transmission rod, and less force can be applied to tighten the nuts on the suspension rods under the same tightening requirements.

[0016] Third, the special wrench for suspension rods provided by this utility model allows for easy and convenient tightening of nuts on suspension rods; firstly, the lighting and monitoring device provided by this utility model, when used together, can provide real-time video monitoring of nuts at high or dark locations, facilitating observation and installation of nuts on suspension rods at a distance; secondly, the laser light and monitoring device provided by this utility model, when used together, allow the laser emitted by the laser light to quickly guide the user to the desired fastening location, enabling the user to quickly fasten the nuts on distant target suspension rods.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

The upper transmission rod 41, middle transmission rod 42, and lower transmission rod 43 are integrally formed, and all three are made of metal. The cross-sections of the upper transmission rod 41, middle transmission rod 42, and lower transmission rod 43 perpendicular to their length direction are all circular. Along the Z direction from the detection component 2 to the rod assembly 1, the orthographic projection of the upper transmission rod 41 completely overlaps with the orthographic projection of the lower transmission rod 43.

[0040] Among them, the transmission rod 42 is a first hollow C-shaped structure, that is, the transmission rod 42 is a round rod bent into the shape of C. The direction of the C-shaped opening of the transmission rod 42 is perpendicular to the direction Z of the detection component 2 pointing to the rod component 1. The center of mass of the first hollow C-shaped structure is not on the same straight line as the axis of the transmission upper rod 41 or the transmission middle rod 42 and the transmission lower rod 43. Both the upper transmission rod 41 and the lower transmission rod 43 are hollow straight cylinders, meaning they are both hollow straight round rods. The length extension direction of the upper transmission rod 41 is parallel to that of the lower transmission rod 43, both along the direction Z from the detection component 2 to the rod assembly 1. The projection of the upper transmission rod 41 in frontal or top-view view coincides with the projection of the lower transmission rod 43 in frontal or top-view view. The upper transmission rod 41 and the lower transmission rod 43 are respectively connected to the two ends of the middle transmission rod 42. The length of the upper transmission rod 41 is not less than the length of the middle transmission rod 42. The tube end of the upper transmission rod 41 closest to the middle transmission rod 42 is fitted into the connecting upper rod 51, and the inner wall of the end of the upper transmission rod 41 away from the middle transmission rod 42 is fixedly connected to a fixing member 31. The length of the lower transmission rod 43 is not greater than the length of the middle transmission rod 42, and the tube end of the lower transmission rod 43 away from the middle transmission rod 42 is fitted into the connecting lower rod 53. The user can hold the transmission rod 42 with one hand, so that the transmission upper rod 41 and transmission lower rod 43 connected at both ends of the transmission rod 42 can rotate within the connecting upper rod 51 and connecting lower rod 53 respectively.

[0041] The connecting rod 5 includes an upper connecting rod 51, a middle connecting rod 52, and a lower connecting rod 53 connected sequentially.

One end of the upper connecting rod 51 and the lower connecting rod 53 are respectively fixedly connected to both ends of the middle connecting rod 52, and both the upper connecting rod 51 and the lower connecting rod 53 are perpendicular to both ends of the middle connecting rod 52. Along the direction ZZ from the detection component 2 to the rod assembly 1, the orthographic projection of the upper connecting rod 51 completely overlaps with the orthographic projection of the lower connecting rod 53.

[0042] The connecting rod 52 is a second hollow U-shaped structure, meaning it is a round rod bent into a U-shape. The opening of the U-shape of the connecting rod 52 is perpendicular to the length extension direction of the connecting upper rod 51 or the connecting lower rod 53. The length of the connecting rod 52 is greater than that of the transmission rod 42.

The perpendicular bisector of the connecting rod 52 in the direction of its length extension coincides with the perpendicular bisector of the transmission rod 42 in the direction of its length extension. The connecting upper rod 51 and the connecting lower rod 53 are both second hollow straight cylinders, meaning they are both hollow straight round rods. The length extension direction of the connecting upper rod 51 is parallel to that of the connecting lower rod 53. The projection of the connecting upper rod 51 in frontal or top-view view coincides with the projection of the connecting lower rod 53 in frontal or top-view view.

By fixing the middle connecting rod 52, the upper connecting rod 51 provides rotational mechanical support for the upper transmission rod 41, and the lower connecting rod 53 provides rotational mechanical support for the lower transmission rod 43.

[0043] Continue to refer to Figures 2-6 As shown, a support rod 61 is provided on the wide side of the support pad 62 near the connecting lower rod 53.

[0044] The aforementioned support rod 61 is an L-shaped round rod of uniform thickness. The support rod 61 can be made of metal, and any cross-section of the support rod 61 along its vertical length is circular. One end of the support rod 61 is fixedly connected to the outer wall of the lower connecting rod 53 away from the transmission rod 42. The length extension direction of the support rod 61 is perpendicular to the length extension direction of the lower connecting rod 53 and perpendicular to the U-shaped bending plane of the transmission rod 42. The support rod 61 can be used to further provide support and stability to the transmission rod 4, thereby increasing the rotational stability of the upper transmission rod 41 within the upper connecting rod 51 and increasing the rotational stability of the lower transmission rod 43 within the lower connecting rod 53.

[0045] The support pad 62 is a rectangular soft pad, including a pad cover (not shown in the figure) and filling material inside the pad cover (not shown in the figure). The pad cover can be made of leather or artificial leather, and the pad cover is a rectangular block when fully filled. A pad cover groove 621 is provided on one side of the pad cover. The opening shape of the pad cover groove 621 is circular. The inner diameter of the pad cover groove 621 is not greater than the outer diameter of the support rod 61, and the groove depth of the pad cover groove 621 is not less than the length of the support rod 61. The pad cover groove 621 is used to insert into the support rod 61, so that the support pad 62 can be fixed on the support rod 61, and the support pad 62 can be rotated and removed for cleaning on the support rod 61.

[0046] Continue to refer to Figure 2 , Figure 5 and Figure 6 As shown, the fixing base 21 is a plate-shaped structure, which can be circular, elliptical, or rectangular. The fixing base 21 can be made of metal or plastic and is fixed to the end of the transmission upper rod 41 away from the transmission middle rod 42 by welding or gluing. The wide surface of the fixing base 21 is perpendicular to the length extension direction of the transmission upper rod 41. A laser light 22, an illumination light 23, and a camera 241 are fixedly connected to the wide surface of the fixing base 21 away from the transmission upper rod 41. Specifically, the fixing base 21 has four through holes, namely a fixing through hole (not shown in the figure), a laser light through hole (not shown in the figure), an illumination light through hole (not shown in the figure), and a camera through hole (not shown in the figure). The laser light through hole is used to fix the laser light 22, the illumination light through hole is used to fix the illumination light 23, and the camera through hole is used to fix the camera 241. The fixing through hole allows the fixing base 21 to be fixedly installed on the transmission upper rod 41. A fixed through hole is formed at the geometric center of the fixed base 21. The fixed through hole is circular in shape, and its diameter is equal to the outer diameter of the upper transmission rod 41. The fixed base 21 can be welded or glued to the end of the upper transmission rod 41 away from the middle transmission rod 42 through the fixed through hole. Laser light through holes, lighting light through holes, and camera through holes are formed around the fixed through hole. The shapes of the laser light through holes, lighting light through holes, and camera through holes can be circular, rectangular, or polygonal; among them, the laser light through holes and camera through holes are arranged adjacent to each other.

[0047] The laser lamp 22 is fixedly connected in the laser lamp through hole of the fixed base 21, and the irradiation direction of the laser lamp 22 is directed above the fastening part 32 away from the transmission rod 41; the model of the laser lamp 22 can be selected as 0201 green laser lamp 22 beads, red laser lamp 22 beads or VCSEL series laser lamp 22 beads. These miniature laser lamp 22 beads have the characteristics of small size, high brightness and low energy consumption.

[0048] The lighting lamp 23 is fixedly connected in the lighting lamp through hole of the fixing base 21. The illumination light of the lighting lamp 23 is in a diffused state, so there is no particular limitation on the specific opening position of the lighting lamp through hole. The model of the lighting lamp 23 can be selected from 0402 lamp beads, 0603 lamp beads, 0805 lamp beads or 1206 lamp beads, etc. These miniature lamp beads are small in size and light in weight, so they are suitable for lighting scenarios with lightweight requirements, such as working on nuts on the suspension rod on the ground.

[0049] The camera 241 is fixedly connected in the camera through hole of the mounting base 21. The monitoring direction of the camera 241 is pointing towards the upper part of the fastening part 32 away from the transmission rod 41. The model of the camera 241 can be selected from G1-IMX258 optical image stabilization camera module or G1-IMX386L1326 small lens camera module, etc. These cameras 241 have the characteristics of small size, light weight and low power consumption, so they are suitable for use in monitoring scenarios where there are requirements for lightweight operation on nuts on the suspension rod on the ground.

[0050] The display 242 is mounted on the outer wall of the connecting rod 51. The display 242 is rectangular in shape and is connected to the connecting rod 51 on one side. The user can flip and fold the display 242 on the connecting rod 51 so that the display 242 is in an open state and a stored state. The display 242 can be an OLED display (organic light-emitting diode), such as ECX344A, or a micro TFT display (Thin Film Transistor), such as ORC-T007101N-V01.

[0051] The battery is located on the inner wall of the support rod 61 near the lower transmission rod 43. The battery is a rechargeable secondary battery, specifically a lithium battery or a nickel-metal hydride battery. Furthermore, the support rod 61 has a charging through-hole near the lower transmission rod 43, and the battery has a charging port 611. The charging port 611 can be shaped like a USB connector (Universal Serial Bus), allowing the battery to be inserted into the support rod 61 through the charging through-hole to charge it. The battery provides power to the laser lamp 22, the lighting lamp 23, and the display 242.

[0052] Switch 25 is located on the outer wall of the upper transmission rod 41 near the transmission end and adjacent to the display 242. Switch 25 can be a sliding switch. By opening a wire hole (not shown in the figure) in the upper transmission rod 41, the wire extends from the battery on the inner wall of the lower transmission rod 43 to the inner wall of the upper transmission rod 41, and is pulled through the wire hole to the outer wall of the upper transmission rod 41. A sliding switch for controlling the closure of the wire is set on the outer wall of the wire hole. The sliding switch includes a rectangular groove and a slider set in the middle of the groove. The closure of the circuit can be controlled by switch 25.

[0053] Continue to refer to Figures 2-7 As shown, the fastener 32 is used to connect the fixing member 31 and the nut on the lifting rod. The fixing member 31 is a cylinder, and its length extends along the direction Z from the detection component 2 to the rod assembly 1. The two ends of the fixing member 31 along its length extension direction are connected to the fastener 32 and the transmission rod 41. The fixing member 31 and the fastener 32 are movably connected, and the fixing member 31 and the transmission rod 41 are fixedly connected. The fixing member 31 has a fixing member through hole 310 along its length extension direction. The shape of the fixing member through hole 310 can be circular. The central axis of the fixing member through hole 310 coincides with the central axis of the transmission rod 41. The fixing member through hole 310 extends through the fixing member 31 along its length extension direction. The fixing member through hole 310 is used to allow the lifting rod to pass through the fixing member 31 and extend into the transmission rod when the nut on the lifting rod is tightened, which facilitates the maximum efficiency of the torque applied to the nut in the vertical direction in this embodiment.

[0054] In a specific application, the special wrench for hanging rods provided in this embodiment can be used for the installation of hanging rods in various locations such as residences, shops, and hospitals. In specific applications,

[0055] First, engage one end of the fastener 32 with the nut on the hoisting rod being installed. Then, turn on the switch 25 and the display 242.

[0056] Then, the user can first put the belt 63 on their waist. According to the user's force application habits, left-handed users place the support pad 62 on their left waist, and right-handed users place the support pad 62 on their right waist. Then tighten the belt 63 appropriately, that is, the belt 63 can be lifted upwards and pulled down from one position, but the special wrench for the suspension rod provided in this embodiment is not completely detached from the waist.

[0057] Finally, the left-handed user holds the connecting rod 52 with their left hand and keeps it still, while their right hand holds the transmission rod 42 and operates the transmission upper rod 41. This allows the end of the suspension rod furthest from the ceiling to pass through the fastening member 32 and the fixing member 310 through the fixing member through hole 310. The suspension rod continues to extend into the transmission upper rod 41, and the user continuously observes the video information (the specific position information of the nut on the suspension rod) on the display 242. When the fastening member 32 and the nut on the suspension rod automatically and completely connect and engage, the right hand begins to rotate the transmission rod 42. The right-handed user operates in the same way, but with the hand position reversed.

[0058] As can be seen from the above embodiments, the special wrench for lifting rods provided by this utility model achieves at least the following beneficial effects:

[0059] First, the special wrench for ceiling hangers provided in this embodiment can tighten the nuts on the ceiling hangers from the ground. Furthermore, this embodiment uses the transmission rod 4 and connecting rod 5 to tighten the nuts on the ceiling hangers remotely, avoiding the need to climb up and down ladders when tightening the nuts, thus improving work efficiency and reducing the probability of accidents while climbing ladders. Additionally, this embodiment provides various types of fasteners 32 that can be replaced, allowing this embodiment to tighten nuts on different hangers. At the same time, the support rod 61 and support pad 62 provided in this embodiment make it convenient to use the special wrench for ceiling hangers with leverage from the waist, making tightening the nuts easier and more convenient.

[0060] Secondly, the special wrench for suspension rods provided in this embodiment can apply a strong tightening force to the nuts on the suspension rods. First, the transmission rod 4 and the connecting rod 5 provided in this embodiment are directly connected. When the transmission rod 4 is rotated, the transmission rod 4 directly engages and acts with the nuts on the suspension rods. Compared with chain drive, the transmission efficiency is high. Under the same tightening requirements, less force can be applied to tighten the nuts on the suspension rods. At the same time, the fastening member 32 provided in this embodiment makes direct contact with the nuts on the suspension rods, and the fastening member 32 has high transmission efficiency between the nuts on the suspension rods and the transmission rod 4. Under the same tightening requirements, even less force can be applied to tighten the nuts on the suspension rods.

[0061] Third, the special wrench for suspension rods provided in this embodiment can easily and conveniently tighten the nuts on the suspension rods; firstly, the lighting lamp 23 and monitoring device 24 provided in this embodiment can be used together to provide real-time video monitoring of nuts at high or dark places, making it convenient for users to observe and install nuts on suspension rods at a distance; secondly, the laser lamp 22 and monitoring device 24 provided in this embodiment can be used together, and the laser emitted by the laser lamp 22 can quickly guide the user to the fastening destination, thereby enabling the user to quickly fasten the nuts on the target suspension rod at a distance.

[0062] In an alternative embodiment, reference continues... Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the fixing member 31 includes a fixing base 311 and a fixing block 312 connected to the fixing base 311, wherein,

[0063] The fixed base 311 is a hollow cylinder, and the fixed block 312 is a hollow pentagonal prism or a hollow hexagonal prism. The fixed base 311 is threadedly connected to the transmission upper rod 41 on the side away from the transmission middle rod 42, and the fixed block 312 is located on the side of the fixed base 311 away from the transmission upper rod 41.

[0064] The fastening component 32 is a cylinder with a connected upper fastening groove 321 and a lower fastening groove 322. The upper fastening groove 321 and the lower fastening groove 322 pass through the probe component 2 in the direction Z pointing to the rod component 1. The shapes of the upper fastening groove 321 and the lower fastening groove 322 match the shape of the fixing block 312. The lower fastening groove 322 is fastened to the outer surface of the fixing block 312.

[0065] Specifically, the fixing component 31 includes a cylindrical fixing base 311 and a fixing block 312 disposed on a top surface of the fixing base 311. The fixing base 311 and the fixing block 312 are an integral structure to enhance the stability and strength of the structure. Any cross-section of the fixing base 311 and the fixing block 312 passing through the perpendicular bisector is convex. The outer diameter of the fixing base 311 is the same as the inner diameter of the transmission upper rod 41. The entire fixing base 311 is concealed inside the upper end of the transmission upper rod 41 away from the transmission middle rod 42. The side of the fixing base 311 near the fixing block 312 is in the same plane as the upper end of the transmission upper rod 41. The fixing block 312 is a pentagonal prism or a hexagonal prism. In this embodiment, the fixing block 312 is a hexagonal prism. The central axis of the fixing block 312 coincides with the central axis of the fixing base 311. The fixing block 312 can be inserted into the fastener 32. Through the fixing block 312 and the fixing base 311, any type of fastener 32 can be connected to the transmission rod 41.

[0066] Reference Figure 8As shown, the upper groove 321 and the lower groove 322 of the fastener are recessed towards each other in the length extension direction of the fastener 32. That is, the opening of the lower groove 322 faces the fixing block 312 and matches the fixing block 312; the opening of the upper groove 321 faces away from the fixing block 312 and matches the nut on the lifting rod. The groove shape of the lower groove 322 of the fastener depends on whether the fixing block 312 is a pentagonal prism or a hexagonal prism. The groove shape of the lower groove 322 of the fastener can be pentagonal or hexagonal. In this embodiment, taking the fixing block 312 as a hexagonal prism as an example, the groove shape of the lower groove 322 of the fastener is hexagonal. The groove depth of the lower groove 322 of the fastener is greater than or equal to the length of the fixing block 312. One end of the fastener 32 along the length direction can be movably fastened to the fixing block 312 through the lower groove 322 of the fastener, and the end of the fastener 32 away from the fixing block 312 can be movably fastened to the nut on the suspension rod through the upper groove 321 of the fastener. The groove depth of the upper groove 321 of the fastener is greater than or equal to the length of the nut on the suspension rod.

[0067] Optionally, the upper groove 321 of the fastener has various groove shapes. This embodiment provides various fastener 32 models, including at least square fasteners, pentagonal fasteners, and hexagonal fasteners; that is, fasteners with square grooves 321, fasteners with pentagonal grooves 321, and fasteners with hexagonal grooves 321. By selecting the upper groove 321 with different groove shapes, the fastener 32 provided in this embodiment can meet the tightening requirements of various nut models.

[0068] Through the above scheme, the fastening member 32 can movably connect the fixing block 312 on the fixing member 31 and the nut on the suspension rod through the upper groove 321 and the lower groove 322 of the fastening member, so that the transmission rod 41 can tighten the nut; furthermore, by selecting different models of fastening members 32, the fixing member 31 can be matched with the nuts on different models of suspension rods, so that the suspension rod special wrench provided in this embodiment can be suitable for different construction conditions, increasing the wide applicability of this embodiment.

[0069] In an alternative embodiment, reference continues... Figure 2 , Figure 7 and Figure 8 As shown, the fastener 32 and the fixing block 312 are made of magnetic metal, and the magnetic attraction of the lower groove 322 of the fastener is greater than the magnetic attraction of the upper groove 321 of the fastener.

[0070] Specifically, the fastener 32 is a magnetic cylinder, and its outer diameter is not less than that of the fixing member 31. The upper groove 321 and the lower groove 322 of the fastener are made of different materials, and the lower groove 322 is more magnetic than the upper groove 321. The lower groove 322 is used to engage with the fixing block 312 in a magnetic manner.

[0071] The above solution enables automatic adsorption between the fastener 32 and the fixing block 312, and between the fastener 32 and the nut on the suspension rod. The operation is simple; it can be closed or opened with just a gentle pull. The magnetic fastening provides a strong attraction and a stable fixing effect through the combination of magnetic force and mechanical structure. It also has the advantage of a beautiful and elegant design, automatically aligning to the correct position, making it more convenient to use.

[0072] In an alternative embodiment, reference continues... Figure 2 As shown, the transmission rod 42 includes a first transmission part 422, a second transmission part 423 and a third transmission part 424 connected in sequence. The first transmission part 422, the second transmission part 423 and the third transmission part 424 form a first hollow C-shaped structure. The first transmission part 422 is connected to the upper transmission rod 41 and the third transmission part 424 is connected to the lower transmission rod 43.

[0073] A transmission rod handle 421 is sleeved on the outer wall of the second transmission part 423. The transmission rod handle 421 is a hollow cylinder. Ball grooves (not shown in the figure) are provided at both ends of the transmission rod handle 421 near the second transmission part 423. The ball grooves are recessed into the outer wall of the transmission rod handle 421, and a sealed cavity is formed between the ball grooves and the outer wall of the transmission rod 42. At least three balls (not shown in the figure) are placed inside the sealed cavity.

[0074] Specifically, the first transmission part 422, the second transmission part 423 and the third transmission part 424 are integrally formed. The end of the first transmission part 422 away from the second transmission part 423 is perpendicularly connected to the upper transmission rod 41. The length extension direction of the second transmission part 423 is parallel to the length extension direction of the upper transmission rod 41. The end of the third transmission part 424 away from the second transmission part 423 is perpendicularly connected to the end of the lower transmission rod 43.

[0075] The transmission rod handle 421 is fitted onto the outer wall of the second transmission part 423.

The inner diameter of the transmission rod handle 421 is not less than the outer diameter of the second transmission part 423, and the length extension direction of the transmission rod handle 421 is the same as the length extension direction of the second transmission part 423. A ball groove is provided on the inner wall of the transmission rod handle 421 near the second transmission part 423 along the circumferential direction. The ball groove is recessed in the direction away from the second transmission part 423. Specifically, there are two ball grooves, which are respectively provided at both ends of the transmission rod handle 421 along its length extension direction. Each ball groove is provided with at least 3 balls, and the ball material can be plastic or metal.

[0076] Through the above scheme, the ball groove and the ball allow the transmission rod handle 421 to rotate freely on the outer wall of the second transmission part 423, thereby enabling the user to smoothly and easily shake the second transmission part 423 by holding the transmission rod handle 421; increasing the user's practical comfort and shaking efficiency.

[0077] In an alternative embodiment, reference continues... Figure 2 As shown, the transmission rod handle 421 has a transmission anti-slip texture (not marked in the figure) on the side away from the second transmission part 423, and the transmission anti-slip texture protrudes to the side away from the second transmission part 423.

[0078] Specifically, the aforementioned transmission anti-slip texture is a protrusion that protrudes away from the second transmission part 423. The transmission anti-slip texture can be a circular, triangular, or elliptical protrusion, or a protruding strip that protrudes along the length or circumference of the transmission rod handle 421. In this embodiment, a protruding strip extending along the length of the transmission rod handle 421 is used as an example, and there are no further limitations on this.

[0079] The above solution enhances the user's grip stability when shaking the transmission rod handle 421, thereby enabling the user to apply rotational force to the nut on the suspension rod and improving the user's force application efficiency.

[0080] In an alternative embodiment, reference continues... Figure 2 As shown, the connecting rod 52 includes a first connecting part 522, a second connecting part 523 and a third connecting part 524 connected in sequence. The first connecting part 522, the second connecting part 523 and the third connecting part 524 form a second hollow C-shaped structure. The first connecting part 522 is connected to the connecting upper rod 51 and the third connecting part 524 is connected to the connecting lower rod 53.

[0081] The outer wall of the second connecting part 523 is fitted with a connecting rod rubber pad 521, which is a hollow circular sleeve. The connecting rod rubber pad 521 has a connecting anti-slip texture (not marked in the figure) on the side away from the second connecting part 523. The connecting anti-slip texture extends along the length of the connecting rod rubber pad 521 and protrudes on the side away from the second connecting part 523.

[0082] Specifically, the first connecting part 522, the second connecting part 523, and the third connecting part 524 are integrally formed; the end of the first connecting part 522 away from the second connecting part 523 is perpendicularly connected to the end of the connecting rod 51 away from the fixing member 31; the two ends of the second connecting part 523 are perpendicularly connected to the first connecting part 522 and the third connecting part 524 respectively, and the projections of the first connecting part 522 and the third connecting part 524 in the length extension direction of the second connecting part 52 coincide with each other; the end of the third connecting part 524 away from the second connecting part 523 is perpendicularly connected to the end of the connecting lower rod 53 near the transmission rod 42.

[0083] The connecting rod rubber pad 521 is fitted onto the outer wall of the second connecting part 523. The connecting rod rubber pad 521 is a hollow circular sleeve, and its material can be plastic or elastic rubber. The inner diameter of the connecting rod rubber pad 521 is not less than the outer diameter of the second connecting part 523, and the connecting rod rubber pad 521 and the second connecting part 523 are interference-fitted. The thickness of the connecting rod rubber pad 521 is at least greater than 5mm. The length extension direction of the connecting rod rubber pad 521 is the same as the length extension direction of the second connecting part 523.

[0084] The aforementioned anti-slip texture is a protrusion that extends away from the second connecting part 523. The anti-slip texture can be a circular, triangular, or elliptical protrusion, or a protruding strip that extends along the length or circumference of the connecting rod pad 521. In this embodiment, a protruding strip extending along the length of the connecting rod pad 521 is used as an example, and no further limitations are made on this.

[0085] The above solution enhances the stability of the user's grip on the connecting rod pad 521 when the user cranks the transmission rod handle 421, and increases the user's grip stability on the connecting rod 52 by increasing the thickness of the connecting rod pad 521, thereby enabling the user to apply rotational force to the nut on the suspension rod and improving the user's force application efficiency.

[0086] In an alternative embodiment, reference continues... Figure 2 As shown, the outer tube wall of the connecting rod 51 on the side away from the connecting middle rod 52 is connected to the display 242 through a universal joint (not marked in the figure). The universal joint is a cross universal coupling.

[0087] Specifically, the display 242 is fitted onto the outer wall of the connecting rod 51 via a universal joint. The display 242 is rectangular in shape, with one wide side connected to the universal joint. The user can fold the display 242 by flipping it over the universal joint, so that the display 242 is in an open or retracted state. When the display 242 is in the open state, the length extension direction of the display 242 is perpendicular to the length extension direction of the connecting rod 51. When the display 242 is in the retracted state, the length extension direction of the display 242 is parallel to the length extension direction of the connecting rod 51, and one screen of the display 242 is in contact with the connecting rod 51 or the transmission rod 41.

[0088] Through the above solution, the universal joint can effectively transmit torque under large angular deviations, withstand large torque and axial force, and enable the display 242 to be rotated arbitrarily, so that the display 242 can be adapted to the user's viewing angle at any angle; in addition, the universal joint has a compact structure and is easy to maintain, which not only reduces production costs but also increases service life.

[0089] In an alternative embodiment, reference continues... Figure 2 and Figure 7 As shown, the inner wall of the upper transmission rod 41 away from the middle transmission rod 42 is provided with an internal thread 410, which extends along the length extension direction of the upper transmission rod 41.

[0090] The outer tube wall of the fixed block 312 is provided with a fixed seat external thread 3110 that matches the transmission rod 4. The transmission rod 41 and the fixed block 312 are threadedly connected by the transmission rod internal thread 410 and the fixed seat external thread 3110.

[0091] Specifically, the internal thread 410 of the transmission rod is provided along the length extension direction of the upper transmission rod 41, and the external thread 3110 of the fixing member is provided along the length extension direction of the external thread 3110 of the fixing seat. Through the internal thread 410 of the transmission rod and the external thread 3110 of the fixing member, the end of the upper transmission rod 41 away from the middle transmission rod 42 or the lower transmission rod 43 can be detachably threadedly connected to the fixing member 31.

[0092] The above solution enables a detachable connection between the transmission rod 41 and the fixing block 312. When the fixing part 31 wears out after long-term use, it can be easily replaced. This facilitates the maintenance and replacement of the fixing part 31, thus extending the service life of the special wrench for lifting rods provided in this embodiment.

[0093] In an alternative embodiment, reference continues... Figure 2 As shown, the transmission rod 4, connecting rod 5 and support rod 6 are made of carbon fiber steel or titanium alloy, and the support pad 62 is made of memory foam.

[0094] Specifically, carbon fiber steel has extremely high strength and stiffness, but weighs only about one-quarter of steel. It also boasts high chemical stability and strong corrosion resistance; titanium alloys have a density of approximately 4.51 g / cm³. 3 It is only 60% as strong as steel, but its strength is comparable to high-strength steel, and titanium alloys also have the same excellent corrosion resistance and fatigue resistance. Memory foam has excellent pressure dispersion capabilities, temperature-sensitive properties, good support, and comfort.

[0095] Through the above solution, the transmission rod 4, connecting rod 5 and support rod 6 maintain a lightweight design while possessing excellent fatigue resistance and strength; the support pad 62 can slowly distribute the pressure on the user's waist, improving comfort.

[0096] Example 2

[0097] Continue to refer to Figure 2 and Figure 6 As shown, the support pad 62 has an arc surface 622 on the side corresponding to the user's waist, and the arc surface 622 is recessed towards the geometric center of the cuboid;

[0098] The length extension direction of the support pad 62 is perpendicular to the length extension direction of the connecting lower rod 53. The support rod 61 is located on the wide side near the connecting lower rod 53. The belt 63 connects the two wide sides of the support pad 62. Along the length extension direction of the support pad 62, the orthographic projection of the belt 63 and the orthographic projection of the support rod 61 do not overlap at all.

[0099] The support pad 62 has a fixing strap (not marked in the figure) fixedly connected to the two wide sides of the arc surface 622 perpendicular to the support pad 62. The fixing strap is rectangular in shape and there is a ring structure between the fixing strap and the support pad 62.

[0100] The waist belt 63 includes a knitted belt 631 and a buckle (not shown in the figure). The knitted belt 631 is rectangular in shape. The buckle includes a female buckle and a female buckle. The female buckle and the female buckle are respectively connected to the two ends of the knitted belt 631. The knitted belt 631 is wrapped around the ring structure along the circumferential direction of the support pad 62, and the female buckle and the female buckle are inserted.

[0101] Specifically, the ring structure refers to the annular space formed after the fixing strap and the support pad 62 are connected, which is used to accommodate the knitted tape 631; the knitted tape 631 is wrapped around the circumference of the support pad 62 to ensure that the waist belt 63 is securely fixed to the support pad 62. The plug-in design of the female buckle and the female buckle facilitates the wearing and adjustment of the waist belt 63.

[0102] A fixing strap is positioned parallel to the depth direction of the groove 621 in the padding. The fixing strap is a rectangular strip, and its material can be the same as the padding material. The length of the fixing strap extends perpendicularly to the length of the support rod 61 and the length of the transmission lower rod 43 or connecting lower rod 53. Both ends of the fixing strap are fixedly connected to the outer wall of the padding, and the fixing method can be sewing. The fixing strap is used to fix the waist belt 63, allowing the support pad 62 to be fixed to the waist belt 63. When the padding is fully filled, the side of the padding away from the fixing strap is an arc surface 622 that is concave towards the fixing strap. The arc surface 622 of the support pad 62 directly contacts the user's waist. The knitted tape 631 is a rectangular long strip, and its material can be cotton or synthetic fiber. Either end of the knitted tape 631 can pass through the fixing strap on the padding, then wrap around the user's waist and close through a buckle. The buckle can be made of plastic or metal.

[0103] Through the above solution, the curved surface 622 can enhance the contact stability of the support pad 62 on the user's waist; enhance the contact comfort between the user's waist and the support pad 62; furthermore, the knitted tape 631 can be closed by means of a buckle, and can be adjusted by means of a snap; the knitted tape 631 and the snap allow the support pad 62 to be firmly fixed to the user's waist.

[0104] The various technical features of this utility model are mutually complementary and functionally supportive of each other. In other words, the technical solution is not a "simple superposition" of technical features among multiple prior art documents. Therefore, this utility model does not fall under the category of "simple superposition" in Chapter 4 of Part II of the Patent Examination Guidelines.
