Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust technology, specifically to maintenance fixtures. Background Technology

[0002] Cars are an important means of transportation in our daily lives, allowing us to reach any destination quickly. As people's living standards improve, more and more people are choosing cars as their mode of transport. However, the increase in motor vehicles has led to a continuous rise in total vehicle exhaust emissions. If strong measures are not taken to control this, the increase in vehicle exhaust pollution will cause more urban environmental problems.

[0003] The automotive exhaust system is a crucial device for collecting and discharging vehicle exhaust gases. It consists of multiple components working together to purify exhaust gases, reduce noise, and ensure compliant emissions. Damage to the automotive exhaust system can lead to excessive emissions of harmful substances, polluting the environment and endangering human health. Therefore, repair shops specializing in automotive exhaust systems are essential. These shops can perform comprehensive repairs and inspections of the exhaust system, ensuring that the system meets standards for continued use. When repairing the automotive exhaust system at a repair shop, various components are clamped using repair jigs to facilitate the repair process.

[0004] However, existing maintenance fixtures have poor versatility, as they can only clamp workpieces of the same specifications, resulting in insufficient adaptability to workpieces of different specifications. Furthermore, since the structure of the fixtures is generally fixed, their adjustment flexibility is low, making it difficult to achieve stable clamping of different types of components through convenient adjustments. Utility Model Content

[0005] In view of this, the present invention provides a maintenance fixture to solve the problems of poor versatility of existing maintenance fixtures, resulting in insufficient adaptability to workpieces of different specifications and low adjustment flexibility.

[0006] In a first aspect, this utility model provides a maintenance clamp, comprising:

[0007] A fixed structure includes a handle assembly and a clamp assembly, one end of the handle assembly being adapted to be mounted in a maintenance position, and the clamp assembly being connected to the other end of the handle assembly;

[0008] The clamping structure includes at least two clamping components and an adjusting component. The two clamping components are respectively disposed on both sides of the clamping base assembly and are both connected to the clamping base assembly. The clamping base assembly is used to adjust the relative position of the two clamping components so that the two clamping components clamp the part to be repaired. The adjusting component is disposed on the clamping base assembly and is connected to the two clamping components.

[0009] Each of the clamping components includes a first clamping member and at least two second clamping members. The first clamping member and the two second clamping members are rotatably connected to the clamping base assembly, and the two second clamping members are respectively disposed on both sides of the first clamping member. The adjusting component is used to drive the first clamping member and the two second clamping members to rotate relative to the clamping base assembly.

[0010] Under the driving action of the adjustment component, the clamping component has a first state in which the first clamping member is vertically arranged and the two second clamping members are inclined, and a second state in which the two second clamping members are vertically arranged and the first clamping member is inclined.

[0011] Beneficial effects: First, the repair fixture is installed in the repair position using the handle assembly. Then, the distance between the two clamping components mounted on both sides is adjusted using the clamping base assembly. The state of the clamping components is adjusted by the adjusting assembly, so that the two clamping components can move closer to each other and clamp parts of different specifications. This helps to improve the versatility of the repair fixture. At the same time, since the parts to be repaired are clamped by two first clamping components or four second clamping components, the clamping stability is improved.

[0012] In one alternative embodiment, the clamping assembly further includes a transmission unit comprising a first gear and a second gear engaged with each other, the first gear being connected to the first clamping member and the second gear being connected to the second clamping member.

[0013] Beneficial effects: By setting the clamping assembly to include a transmission unit, and setting the transmission unit to include a first gear and a second gear, the first gear and the second paper wheel are meshed together, and the first gear is connected to the first clamping member, while the second gear is connected to the second clamping member. In this way, the transmission connection between the first clamping member and the second clamping member can be realized. That is, when the first clamping member rotates relative to the clamping seat assembly, the second clamping member will rotate synchronously relative to the clamping seat assembly under the drive of the transmission unit. Thus, under the driving action of the adjustment component, the clamping assembly can switch between the first state and the second state.

[0014] In one optional embodiment, the clamping assembly further includes a support base, the support base including a mounting block, at least two partitions, a first rotating shaft and at least two second rotating shafts, the mounting block having a mounting portion, the two partitions being spaced apart within the mounting portion, the first clamping member being rotatably disposed between the two partitions via the first rotating shaft, and any second clamping member being rotatably disposed between the mounting block and the partitions via a second rotating shaft, the first gear being connected to the end of the first rotating shaft, and the second gear being connected to the end of the second rotating shaft.

[0015] Beneficial effects: By setting the clamping assembly to include a support base, and the support base including a mounting block, two partitions, a first rotating shaft, and two second rotating shafts, the partitions in this embodiment are partition plates. The mounting block has a mounting portion, which in this embodiment is a mounting groove. The two partitions are spaced apart in the mounting portion, thereby dividing the mounting portion into three sections. The first clamping member can be rotatably disposed between the two partitions via the first rotating shaft, and the two second clamping members can be rotatably disposed between the mounting block and one partition via the second rotating shaft. Furthermore, the first clamping member and the second clamping member can be rotatably connected to the clamping assembly via the support base. In addition, the first gear is connected to the end of the first rotating shaft, and the second gear is connected to the end of the second rotating shaft, thus increasing the distance between the first clamping member and the second clamping member.

[0016] In one optional embodiment, the clamping assembly includes a strip seat, a drive unit, and at least two side frames. The strip seat is connected to the handle assembly and has a mounting cavity. The drive unit includes a drive member and at least two moving members. The two moving members are spaced apart within the mounting cavity. The drive member is adapted to pass through the two moving members and has a first thread and a second thread with opposite helical directions. The first thread and the second thread are threadedly connected to one of the moving members, respectively. Each of the side frames is connected to one of the moving members, and the two side frames are respectively connected to the first clamping member and the second clamping member.

[0017] Beneficial effects: By setting the clamping assembly to include a strip seat, a drive unit, and two side frames, wherein the strip seat is connected to the handle assembly and has a mounting cavity, the drive unit includes a drive member and two moving members, which in this embodiment drive a screw and a moving screw block respectively, wherein the two moving members are spaced apart in the mounting cavity, and the drive member can pass through the two moving members, and the drive member has a first thread and a second thread with opposite helical directions. When the drive member passes through the two moving members, the first thread is threadedly connected to one moving member, and the second thread is threadedly connected to the other moving member. Thus, when the drive member rotates, the two moving members can move closer or further apart through the threads. The two side frames are each connected to a moving member, and each side frame is connected to a first clamping member and a second clamping member. Thus, when the two moving members move closer or further apart, the two side frames can move closer or further apart through the two moving members, thereby realizing the movement of the first clamping member and the second clamping member, and thus realizing the clamping operation of the first clamping member or the second clamping member on the workpiece to be repaired.

[0018] In one optional embodiment, the adjusting assembly includes a hollow rod, at least two rotating members, at least two displacement members, at least two connecting members, and at least two sliding members. The hollow rod has a receiving cavity with openings at both ends. A first limiting portion communicating with the receiving cavity is provided at each end of the hollow rod. One end of each rotating member is inserted into the receiving cavity through one of the openings, and the other end is rotatably connected to the side frame. Each rotating member is provided with a blocking portion, which is adapted to be disposed within the first limiting portion to limit the rotating member.

[0019] The side frame is provided with a second limiting part, the rotating part has a third thread and a fourth thread with opposite helical directions, one end of each of the two displacement parts is threadedly connected to the third thread and the fourth thread respectively, and the other end is connected to the second limiting part to limit the displacement parts.

[0020] The first clamping member has a third limiting part, the sliding member is slidably disposed in the third limiting part, one end of the connecting member is connected to the displacement member, and the other end is hinged to the sliding member.

[0021] Beneficial effects: By setting the adjustment component including a hollow rod, two rotating parts, two displacement parts, two connecting parts, and two sliding parts, the rotating parts, displacement parts, connecting parts, and sliding parts in this embodiment are respectively a rotating screw, a displacement block, a connecting rod, and a slider. The hollow rod has a receiving cavity with openings at both ends, and each end of the hollow rod has a first limiting part that communicates with the receiving cavity. In this embodiment, the first limiting part is a first limiting groove. One end of each rotating part can be inserted into the receiving cavity through the opening, and the other end is rotatably connected to the side frame. The rotating part is provided with a blocking part, which in this embodiment is a blocking block. When the end of the rotating part is inserted into the receiving cavity, the blocking part is located in the first limiting part, so that the rotating part can be limited by the blocking part and the first limiting part, thereby limiting the displacement of the two side frames and preventing the two side frames from contacting each other.

[0022] In addition, a second limiting part is provided on the side frame. In this embodiment, the second limiting part is a second limiting groove. The rotating part has a third thread and a fourth thread with opposite helical directions. One end of the two displacement parts is threadedly connected to the third thread and the fourth thread respectively, and the other end is slidably disposed in the second limiting part on the side frame. In this way, when the rotating part rotates, the two displacement parts can move closer to each other or further away from each other through the threads, and the second limiting part can limit the displacement parts.

[0023] The first clamping member has a third limiting part, which is a third limiting groove in this embodiment. The sliding member is slidably disposed in the third limiting groove. One end of the connecting member is connected to the displacement member, and the other end is hinged to the sliding member. In this way, when the two displacement members approach or move away from each other, the connecting member can drive the sliding member to slide in the third limiting part, and drive the first clamping member to rotate through the sliding member. The first clamping member can then drive the second clamping member to rotate through the transmission unit. In this way, the state switching of the clamping assembly can be realized.

[0024] In one optional embodiment, the handle assembly includes an adapter, a rotating component, a short shaft, a positioning component, and a support unit. One end of the adapter is connected to the clamp assembly, and the other end has a rotating cavity. The short shaft is disposed in the rotating cavity, and the rotating component is rotatably disposed on the short shaft. The rotating component has a plurality of positioning portions. The positioning end of the positioning component is adapted to pass through the adapter and connect with the positioning portions to fix the rotating component. The support unit is connected to the rotating component and is adapted to be installed in a maintenance position.

[0025] Beneficial effects: By setting the handle assembly to include an adapter, a rotating component, a short shaft, a positioning component, and a support unit, the adapter, rotating component, and positioning component in this embodiment are respectively an adapter rod, a rotating block, and a positioning screw. One end of the adapter is connected to the clamping assembly, and the other end has a rotating cavity. The short shaft is disposed in the rotating cavity, and the rotating component is rotatably disposed on the short shaft, so that the rotating component can rotate in the rotating cavity through the short shaft. The rotating component has several positioning parts, which are positioning grooves in this embodiment. The positioning end of the positioning component can pass through the adapter and connect to the positioning part, thereby fixing the rotating component. The support unit is connected to the rotating component and can be installed in the maintenance position. Thus, through the rotating component that can rotate in the rotating cavity and the fixing effect of the positioning component on the rotating component, the support unit can rotate relative to the clamping assembly, thereby corresponding to the maintenance position and being installed in the maintenance position.

[0026] In one alternative embodiment, the handle assembly further includes a fastening unit comprising at least two fasteners and at least two fixing members, the two fixing members being respectively disposed on both sides of the adapter and both connected to the adapter, and any one of the fasteners being adapted to pass through one of the fixing members and be threadedly connected to the fixing member.

[0027] Beneficial effects: By including a fastening unit in the handle assembly, the fastening unit specifically includes two fasteners and two fixing members. In this embodiment, the fasteners and fixing members are fastening screws and fixing plates. The two fixing members are respectively located on both sides of the adapter and are connected to the adapter. The fixing members are specifically L-shaped structures, so that there is a gap between the fixing members and the adapter when they are connected. The handle assembly can be inserted into the installation position through this gap. At this time, the fasteners can penetrate the fixing members and abut against the installation position. In this way, the handle assembly can be installed in the installation position. Since the fasteners and fixing members are connected by threads, the fasteners can be fixed by the threads when they abut against the installation position, thereby fixing the handle assembly in the installation position.

[0028] In one optional embodiment, the support unit includes a telescopic member, a base, and a locking member. The fixed end of the telescopic member is connected to the rotating member, and the telescopic end of the telescopic member is connected to the base. The base is adapted to be installed in a maintenance position. The locking member is disposed between the fixed end and the telescopic end of the telescopic member to lock the telescopic member.

[0029] Beneficial effects: By setting the support unit including a telescopic component, a base, and a locking component, the telescopic component and the locking component in this embodiment are a telescopic rod and a locking screw, respectively. The fixed end of the telescopic component is connected to the rotating component, and the telescopic end of the telescopic component is connected to the base, so that the base can be installed in the maintenance position under the action of the telescopic end of the telescopic component. The locking component is set between the fixed end and the telescopic end of the telescopic component, so as to fix the telescopic component and restrict its extension and retraction.

[0030] In one alternative embodiment, an anti-slip structure is further included, the anti-slip structure comprising a first anti-slip element fitted onto the telescopic element.

[0031] Beneficial effects: By setting an anti-slip structure on the maintenance jig, the anti-slip structure specifically includes a first anti-slip component, which in this embodiment is a rubber sleeve. The first anti-slip component is specifically sleeved on the telescopic component, thus increasing the stability of the user when holding the maintenance jig.

[0032] In one optional embodiment, the anti-slip structure further includes at least two second anti-slip components, one of which is disposed on the side of the first clamping member close to the part to be repaired, and the other of which is disposed on the side of the second clamping member close to the part to be repaired.

[0033] Beneficial effects: The anti-slip structure also includes two second anti-slip components. In this embodiment, the second anti-slip components are anti-slip pads. One of the second anti-slip components is specifically located on the side of the first clamping component near the part to be repaired, and the other second anti-slip component is located on the side of the second clamping component near the part to be repaired. In this way, when the first clamping component or the second clamping component clamps the part to be repaired, the second anti-slip component can increase the friction between the clamping component and the part to be repaired, and prevent the part to be repaired from falling out of the clamping components.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0045] According to embodiments of the present invention, in one aspect, a maintenance clamp is provided, such as... Figures 1 to 6As shown, the device includes a fixing structure and a clamping structure. The fixing structure includes a handle assembly and a clamping assembly 12. One end of the handle assembly is adapted to be installed in a maintenance position, and the clamping assembly 12 is connected to the other end of the handle assembly. The clamping structure includes at least two clamping assemblies 21 and an adjusting assembly. The two clamping assemblies 21 are respectively disposed on both sides of the clamping assembly 12 and are both connected to the clamping assembly 12. The clamping assembly 12 is used to adjust the relative position of the two clamping assemblies 21 so that the two clamping assemblies 21 clamp the part to be maintained. The adjusting assembly is disposed on the clamping assembly 12 and is connected to the two clamping assemblies 21. Each clamping assembly 21 includes a first... The clamping component 211 and at least two second clamping components 212 are rotatably connected to the clamping base assembly 12. The two second clamping components 212 are respectively disposed on both sides of the first clamping component 211. The adjusting component is used to drive the first clamping component 211 and the two second clamping components 212 to rotate relative to the clamping base assembly 12. Under the driving action of the adjusting component, the clamping assembly 21 has a first state in which the first clamping component 211 is vertically arranged and the two second clamping components 212 are inclined, and a second state in which the two second clamping components 212 are vertically arranged and the first clamping component 211 is inclined.

[0046] The repair fixture described above utilizes a clamping structure mounted on a fixed structure. This fixed structure includes a handle assembly and a clamping base assembly 12. One end of the handle assembly can be installed in the repair position, and the clamping base assembly 12 is connected to the other end of the handle assembly. The clamping structure specifically includes two clamping components 21 and an adjustment component. The two clamping components 21 are respectively located on both sides of the clamping base assembly 12, and each clamping component 21 is connected to the clamping base assembly 12. The clamping base assembly 12 can adjust the positions of the two clamping components 21 mounted on its sides, allowing the two clamping components 21 to adapt to the dimensions of the part to be repaired and clamp it securely. The adjustment component is located on the clamping base assembly 12, and its adjustment end is connected to both clamping components 21, allowing for adjustment of the two clamping components 21.

[0047] Specifically, each clamping assembly 21 includes a first clamping member 211 and two second clamping members 212. In this embodiment, the first clamping member 211 and the second clamping member 212 are respectively a first clamping plate and a second clamping plate. The first clamping member 211 and the second clamping member 212 are rotatably connected to the clamping base assembly 12. The two first clamping members 211 are respectively disposed on both sides of the first clamping member 211. Thus, under the driving action of the adjusting assembly, the first clamping member 211 and the second clamping member 212 can rotate relative to the clamping base assembly 12. This allows the clamping assembly 21 to have a first state in which the first clamping member 211 is vertically arranged and the two second clamping members 212 are inclined. In the first state, the part to be repaired can be clamped by the two first clamping members 211. In the second state, the part to be repaired can be clamped by the four second clamping members 212.

[0048] In the first state, since the first clamping members 211 of both clamping assemblies 21 are vertically arranged, when the clamping base assembly 12 brings the two clamping assemblies 21 close to each other, the two first clamping members 211 can clamp the small parts to be repaired. Meanwhile, the two second clamping members 212 are inclined, so that the two second clamping members 212 do not interfere with the first clamping members 211 clamping the parts to be repaired. In the second state, since the two second clamping members 212 of both clamping assemblies 21 are vertically arranged, and the two second clamping members 212 of each clamping assembly 21 are spaced apart, the clamping range of the second clamping members 212 can be increased. Therefore, when the clamping assembly 12 brings the two clamping assemblies 21 close to each other, the corresponding second clamping members 212 can clamp the larger parts to be repaired. Since the two first clamping members 211 are inclined, they will not interfere with the second clamping members 212 clamping the parts to be repaired. Thus, by adjusting the state of the clamping assembly 21, the clamping assembly 21 can clamp parts to be repaired of different sizes, which is beneficial to improving the versatility of the repair fixture. At the same time, since the parts to be repaired are clamped by the two first clamping members 211 or the four second clamping members 212, the clamping stability is improved.

[0049] In summary, the repair fixture is first installed in the repair position using the handle assembly. Then, the distance between the two clamping components 21, which are rotatably mounted on both sides of the clamping base assembly 12, is adjusted using the adjusting assembly. This allows the two clamping components 21 to move closer to each other and clamp parts of different specifications, thereby improving the versatility of the repair fixture. At the same time, since the parts to be repaired are clamped by two first clamping components 211 or four second clamping components 212, the clamping stability is improved.

[0050] In one embodiment, such as Figure 2 As shown, the clamping assembly 21 also includes a transmission unit 213, which includes a first gear 2131 and a second gear 2132 that are meshed together. The first gear 2131 is connected to the first clamping member 211, and the second gear 2132 is connected to the second clamping member 212.

[0051] The maintenance fixture with the above structure further includes a transmission unit 213 by setting the clamping assembly 21. The transmission unit 213 includes a first gear 2131 and a second gear 2132. The first gear 2131 and the second paper wheel are meshed together. The first gear 2131 is connected to the first clamping member 211, and the second gear 2132 is connected to the second clamping member 212. In this way, the transmission connection between the first clamping member 211 and the second clamping member 212 can be realized. That is, when the first clamping member 211 rotates relative to the clamping seat assembly 12, the second clamping member 212 will rotate synchronously relative to the clamping seat assembly 12 under the drive of the transmission unit 213. Thus, under the driving action of the adjustment component, the clamping assembly 21 can switch between the first state and the second state.

[0052] In one embodiment, such as Figure 2 As shown, the clamping assembly 21 also includes a support base 214. The support base 214 includes a mounting block 2141, at least two partitions 2142, a first rotating shaft 2143, and at least two second rotating shafts 2144. The mounting block 2141 has a mounting portion, and the two partitions 2142 are spaced apart within the mounting portion. The first clamping member 211 is rotatably disposed between the two partitions 2142 via the first rotating shaft 2143. Any second clamping member 212 is rotatably disposed between the mounting block 2141 and the partitions 2142 via a second rotating shaft 2144. The first gear 2131 is connected to the end of the first rotating shaft 2143, and the second gear 2132 is connected to the end of the second rotating shaft 2144.

[0053] The maintenance fixture with the above-described structure further includes a support base 214 by setting the clamping assembly 21. The support base 214 includes a mounting block 2141, two partitions 2142, a first rotating shaft 2143, and two second rotating shafts 2144. In this embodiment, the partitions 2142 are partition plates. The mounting block 2141 has a mounting portion, which is a mounting groove in this embodiment. The two partitions 2142 are spaced apart within the mounting portion, thereby dividing the mounting portion into three sections. The first clamping member 211 can be rotated through the first rotating shaft 2143. The first clamping member 211 and the second clamping member 212 are respectively rotatably disposed between the mounting block 2141 and the partition 2142 via the second rotating shaft 2144. Thus, the first clamping member 211 and the second clamping member 212 can be rotatably connected to the clamping assembly 12 via the support base 214. In addition, the first gear 2131 is connected to the end of the first rotating shaft 2143, and the second gear 2132 is connected to the end of the second rotating shaft 2144. In this way, the distance between the first clamping member 211 and the second clamping member 212 can be increased.

[0054] In one embodiment, such as Figure 1 and Figure 6 As shown, the clamping assembly 12 includes a strip seat 121, a drive unit 122, and at least two side frames 123. The strip seat 121 is connected to the handle assembly and has a mounting cavity. The drive unit 122 includes a drive member 1221 and at least two moving members 1122. The two moving members 1122 are spaced apart in the mounting cavity. The drive member 1221 is adapted to pass through the two moving members 1122 and has a first thread and a second thread with opposite helical directions. The first thread and the second thread are threadedly connected to a moving member 1122, respectively. Each side frame 123 is connected to a moving member 1122, and the two side frames 123 are connected to a first clamping member 211 and a second clamping member 212, respectively.

[0055] The maintenance fixture described above includes a clamp assembly 12 comprising a strip base 121, a drive unit 122, and two side frames 123. The strip base 121 is connected to the handle assembly and has a mounting cavity. The drive unit 122 includes a drive member 1221 and two moving members 1122. In this embodiment, the drive member 1221 and the moving members 1122 respectively drive a screw and a moving screw block. The two moving members 1122 are spaced apart within the mounting cavity. The drive member 1221 can penetrate both moving members 1122. The drive member 1221 has a first thread and a second thread with opposite helical directions. When the drive member 1221 penetrates both moving members 1122, the first thread interacts with one of the moving members 1122. The first moving part 1122 is connected by a threaded connection, and the second thread is connected to another moving part 1122. Thus, when the drive part 1221 rotates, the two moving parts 1122 can move closer or further apart through the threads. The two side frames 123 are respectively connected to a moving part 1122, and each side frame 123 is connected to the first clamping part 211 and the second clamping part 212. Thus, when the two moving parts 1122 move closer or further apart, the two side frames 123 can move closer or further apart through the two moving parts 1122, thereby enabling the first clamping part 211 and the second clamping part 212 to move closer or further apart, and thus enabling the first clamping part 211 or the second clamping part 212 to perform clamping operations on the part to be repaired.

[0056] In one embodiment, such as Figures 1 to 4 As shown, the adjustment assembly includes a hollow rod 221, at least two rotating members 222, at least two displacement members 223, at least two connecting members 224, and at least two sliding members 225. The hollow rod 221 has a receiving cavity with openings at both ends. Each end of the hollow rod 221 has a first limiting part 2211 communicating with the receiving cavity. One end of each rotating member 222 is inserted into the receiving cavity through an opening, and the other end is rotatably connected to the side frame 123. Each rotating member 222 is provided with a blocking part 2221, which is adapted to be positioned on the first... The rotating member 222 is limited within the limiting part 2211; a second limiting part is provided on the side frame 123; the rotating member 222 has a third thread and a fourth thread with opposite helical directions; one end of each of the two displacement members 223 is threadedly connected to the third thread and the fourth thread respectively, and the other end is connected to the second limiting part to limit the displacement member 223; a third limiting part 2111 is provided on the first clamping member 211; a sliding member 225 is slidably disposed within the third limiting part 2111; one end of the connecting member 224 is connected to the displacement member 223, and the other end is hinged to the sliding member 225.

[0057] The maintenance fixture with the above-described structure includes an adjustment assembly comprising a hollow rod 221, two rotating members 222, two displacement members 223, two connecting members 224, and two sliding members 225. In this embodiment, the rotating members 222, displacement members 223, connecting members 224, and sliding members 225 are respectively a rotating screw, a displacement block, a connecting rod, and a slider. The hollow rod 221 has a receiving cavity with openings at both ends, and each end of the hollow rod 221 has a first limiting part 2211 communicating with the receiving cavity. In this embodiment, the first limiting part 2211 is a first limiting... Each rotating component 222 has one end that can be inserted into the receiving cavity through the opening, and the other end that is rotatably connected to the side frame 123. The rotating component 222 is provided with a blocking part 2221, which is a blocking block in this embodiment. When the end of the rotating component 222 is inserted into the receiving cavity, the blocking part 2221 is located in the first limiting part 2211, so that the rotating component 222 can be limited by the blocking part 2221 and the first limiting part 2211, thereby limiting the displacement of the two side frames 123 and preventing the two side frames 123 from contacting each other.

[0058] In addition, a second limiting part is provided on the side frame 123. In this embodiment, the second limiting part is a second limiting groove. The rotating member 222 has a third thread and a fourth thread with opposite helical directions. One end of the two displacement members 223 is threadedly connected to the third thread and the fourth thread, respectively, and the other end is slidably disposed in the second limiting part on the side frame 123. In this way, when the rotating member 222 rotates, the two displacement members 223 can move closer to each other or further away from each other through the threads, and the second limiting part can limit the displacement members 223.

[0059] The first clamping member 211 has a third limiting part 2111, which is a third limiting groove in this embodiment. The sliding member 225 is slidably disposed in the third limiting groove. One end of the connecting member 224 is connected to the displacement member 223, and the other end is hinged to the sliding member 225. Thus, when the two displacement members 223 approach or move away from each other, the connecting member 224 can drive the sliding member 225 to slide in the third limiting part 2111, and drive the first clamping member 211 to rotate through the sliding member 225. The first clamping member 211 can then drive the second clamping member 212 to rotate through the transmission unit 213. In this way, the state switching of the clamping assembly 21 can be realized.

[0060] In one embodiment, such as Figure 1 and Figure 3As shown, the handle assembly includes an adapter 111, a rotating member 112, a short shaft 113, a positioning member 114, and a support unit 115. One end of the adapter 111 is connected to the clamp assembly 12, and the other end has a rotating cavity. The short shaft 113 is disposed in the rotating cavity. The rotating member 112 is rotatably disposed on the short shaft 113. The rotating member 112 has several positioning parts. The positioning end of the positioning member 114 is adapted to pass through the adapter 111 and connect with the positioning parts to fix the rotating member 112. The support unit 115 is connected to the rotating member 112, and the support unit 115 is adapted to be installed in the maintenance position.

[0061] The maintenance fixture described above includes a handle assembly comprising an adapter 111, a rotating component 112, a short shaft 113, a positioning component 114, and a support unit 115. In this embodiment, the adapter 111, rotating component 112, and positioning component 114 are respectively an adapter rod, a rotating block, and a positioning screw. One end of the adapter 111 is connected to the clamping assembly 12, and the other end has a rotating cavity. The short shaft 113 is disposed within the rotating cavity, and the rotating component 112 is rotatably mounted on the short shaft 113, allowing the rotating component 112 to rotate within the rotating cavity via the short shaft 113. Furthermore, the rotating component 112 is provided with several positioning parts, which are positioning grooves in this embodiment. The positioning end of the positioning component 114 can pass through the adapter 111 and connect to the positioning part, thereby fixing the rotating component 112. The support unit 115 is connected to the rotating component 112, and the support unit 115 can be installed in the maintenance position. Thus, through the rotating component 112 that can rotate in the rotating cavity and the fixing effect of the positioning component 114 on the rotating component 112, the support unit 115 can rotate relative to the clamp assembly 12, thereby corresponding to the maintenance position and being installed in the maintenance position.

[0062] In one embodiment, such as Figure 1 As shown, the handle assembly also includes a fastening unit 116, which includes at least two fasteners 1161 and at least two fixing members 1162. The two fixing members 1162 are respectively disposed on both sides of the adapter 111 and are both connected to the adapter 111. Any fastener 1161 is adapted to pass through a fixing member 1162 and be threadedly connected to the fixing member 1162.

[0063] The maintenance clamp described above, by providing a handle assembly, also includes a fastening unit 116. The fastening unit 116 specifically includes two fasteners 1161 and two fixing members 1162. In this embodiment, the fasteners 1161 and fixing members 1162 are fastening screws and fixing plates, respectively. The two fixing members 1162 are respectively located on both sides of the adapter 111, and both fixing members 1162 are connected to the adapter 111. The fixing members 1162 are specifically L-shaped structures, thereby ensuring that the fixing members 1162 and the adapter 111... When 11 is connected, there will be a gap between the fixing member 1162 and the adapter 111. The handle assembly can be inserted into the installation position through this gap. At this time, the fastener 1161 can pass through the fixing member 1162 and abut against the installation position. In this way, the handle assembly can be installed in the installation position. Since the fastener 1161 and the fixing member 1162 are connected by threads, when the fastener 1161 abuts against the installation position, the fastener 1161 can be fixed by the threads, thereby fixing the handle assembly in the installation position.

[0064] In one embodiment, such as Figure 1 As shown, the support unit 115 includes a telescopic member 1151, a base 1152, and a locking member 1153. The fixed end of the telescopic member 1151 is connected to the rotating member 112, and the telescopic end of the telescopic member 1151 is connected to the base 1152. The base 1152 is suitable for installation in a maintenance position. The locking member 1153 is disposed between the fixed end and the telescopic end of the telescopic member 1151 to lock the telescopic member 1151.

[0065] The maintenance fixture with the above-described structure includes a support unit 115 comprising a telescopic member 1151, a base 1152, and a locking member 1153. In this embodiment, the telescopic member 1151 and the locking member 1153 are a telescopic rod and a locking screw, respectively. The fixed end of the telescopic member 1151 is connected to the rotating member 112, and the telescopic end of the telescopic member 1151 is connected to the base 1152, thereby allowing the base 1152 to be installed in the maintenance position under the action of the telescopic end of the telescopic member 1151. The locking member 1153 is disposed between the fixed end and the telescopic end of the telescopic member 1151, thereby fixing the telescopic member 1151 and restricting its extension and retraction.

[0066] In one embodiment, such as Figures 1 to 6 As shown, it also includes an anti-slip structure, which includes a first anti-slip component, which is sleeved on the telescopic component 1151.

[0067] The maintenance jig with the above structure has an anti-slip structure on it. The anti-slip structure specifically includes a first anti-slip component, which is a rubber sleeve in this embodiment. The first anti-slip component is specifically sleeved on the telescopic component 1151, which can increase the stability of the user when holding the maintenance jig.

[0068] In one embodiment, such as Figures 1 to 6 As shown, the anti-slip structure also includes at least two second anti-slip components. One second anti-slip component is disposed on the side of the first clamping component 211 near the component to be repaired, and the other second anti-slip component is disposed on the side of the second clamping component 212 near the component to be repaired.

[0069] The maintenance fixture with the above-described structure also includes two second anti-slip components by setting an anti-slip structure. In this embodiment, the second anti-slip components are anti-slip pads. One of the second anti-slip components is specifically set on the side of the first clamping member 211 near the part to be repaired, and the other second anti-slip component is set on the side of the second clamping member 212 near the part to be repaired. In this way, when the first clamping member 211 or the second clamping member 212 clamps the part to be repaired, the second anti-slip component can increase the friction between the clamping member and the part to be repaired, and prevent the part to be repaired from falling out of the clamping members.

[0070] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
