[0002] The vehicle wheel cylinder usually includes two oppositely connected first wheel cylinder components and second wheel cylinder components, and a large spring is provided between the first wheel cylinder component and the second wheel cylinder component, and the first wheel cylinder component and the second wheel cylinder component are fixedly connected together by a fixing clamp.

[0003] During maintenance, maintenance personnel need to remove the fixing clamp and separate the first sub-pump assembly and the second sub-pump assembly before replacing and repairing the corresponding parts; after replacing and repairing the corresponding parts, the first sub-pump assembly and the second sub-pump assembly need to be docked and fixed again. Since there is a large spring between the first sub-pump assembly and the second sub-pump assembly, a certain force needs to be applied to dock the first sub-pump assembly and the second sub-pump assembly so as to be fixed together by the fixing clamp; in the prior art, a bench vise is usually used to apply pressure to the first sub-pump assembly and the second sub-pump assembly, but due to the special shapes of the first sub-pump assembly and the second sub-pump assembly, and the top of the first sub-pump assembly has a first rod structure and the bottom of the second sub-pump assembly has a second rod structure, the bench vise cannot clamp the first sub-pump assembly and the second sub-pump assembly well, and the position of the first sub-pump assembly or the second sub-pump assembly may be offset and popped out during the clamping process, posing a safety hazard. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a slave pump maintenance tool, which is provided with a first limit assembly matching the top of the first slave pump assembly, and a second limit assembly matching the bottom of the second slave pump assembly. The second limit assembly is driven by a driving assembly to move closer to and away from the first limit assembly, and a guide assembly is provided to guide the movement of the second limit assembly, which can more stably apply pressure to the first slave pump assembly and the second slave pump assembly, so as to facilitate maintenance personnel to install the fixing clamp.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A slave cylinder maintenance tool, comprising:

[0007] A first limiting assembly, comprising a first abutting portion for abutting against a top portion of a first sub-pump assembly in a sub-pump, wherein the first abutting portion is provided with a first avoidance through hole for a first rod structure on the top portion of the first sub-pump assembly to pass through;

[0008] A second stopper assembly, comprising a second abutting portion for abutting against the bottom of a second sub-pump assembly in the sub-pump, and the second abutting portion is provided with a second avoidance through-hole for a second rod structure on the bottom of the second sub-pump assembly to pass through, the second abutting portion is arranged opposite to the first abutting portion, and the distance between the axis of the first avoidance through-hole and the axis of the second avoidance through-hole matches the distance between the axis of the first rod structure and the axis of the second rod structure in the sub-pump;

[0009] A guide assembly, wherein the first limiting assembly and the second limiting assembly are arranged on the guide assembly, and the guide assembly is extended along the direction from the first abutting portion to the second abutting portion; and the second limiting assembly can move along the extension direction of the guide assembly;

[0010] A driving assembly is connected to the second limiting assembly to drive it to move along the extension direction of the guiding assembly.

[0011] With the above structure, maintenance personnel can align the second rod structure of the second sub-pump assembly with the second avoidance through-hole of the second abutment part and make it pass through the second avoidance through-hole, so that the bottom of the second sub-pump assembly abuts against the second abutment part; then align the first sub-pump assembly with the second sub-pump assembly and place it on the second sub-pump assembly, at which time the first rod structure on the first sub-pump assembly aligns with the first avoidance through-hole of the first abutment part; since there is a spring between the first sub-pump assembly and the second sub-pump assembly, the two are in a separated state; the driving assembly drives the second limiting assembly to move, and moves toward the first limiting assembly side under the guidance of the guiding assembly, that is, the second abutment part moves toward the second abutment part side, at which time the first sub-pump assembly will abut against the first abutment part; the second sub-pump assembly overcomes the spring force under the drive of the second abutment part and approaches the first sub-pump assembly until the second sub-pump assembly and the first sub-pump assembly are completely installed; maintenance personnel can fix the first sub-pump assembly and the second sub-pump assembly together by fixing the clamp; finally, the driving assembly drives the second limiting assembly away from the first limiting assembly, so that the maintenance personnel can take out the sub-pump and prepare for the next operation;

[0012] Specifically, the axis of the first rod structure and the axis of the second rod structure in the sub-pump are collinear, that is, the first rod structure and the second rod structure are coaxial; correspondingly, the axis of the first avoidance perforation and the axis of the second avoidance perforation are collinear, that is, the first avoidance perforation and the second avoidance perforation are coaxial.

[0013] Further, the guide assembly includes a sliding rod, and the sliding rod is extended along the direction from the first abutting portion to the second abutting portion;

[0014] Correspondingly, a sliding hole matching the sliding rod is provided on the second limiting assembly, and the axis of the sliding hole is perpendicular to the second abutting portion; the second limiting assembly is sleeved on the sliding rod through the sliding hole.

[0015] With the above structure, the slide rod cooperates with the slide hole to guide the movement of the second position-limiting assembly, and can make the movement of the second position-limiting assembly more stable.

[0016] Further, the second limiting assembly includes a sliding cylinder, the axis of the sliding cylinder is perpendicular to the second abutting portion, and the inner hole of the sliding cylinder is formed as the sliding hole.

[0017] The above structure makes the structural setting of the second limit assembly more reasonable, facilitates the realization of the sliding hole, and facilitates actual production and processing.

[0018] Furthermore, a boss is protruded from the top of the first slave pump assembly, and two bosses are symmetrically arranged on both sides of the first rod structure;

[0019] The width of the first abutment portion is less than or equal to the shortest distance between the outer walls of the two first rod structures; the center of the first avoidance perforation is located on the midline of the width direction of the first abutment portion. Specifically, the first avoidance perforation is arranged at the center position of the first abutment portion, and the second avoidance perforation is arranged at the center position of the second abutment portion.

[0020] By adopting the above structure, the structure of the first abutting portion is more reasonable, so that it can avoid the protruding column on the first sub-cylinder assembly to abut against the top of the first sub-cylinder assembly.

[0021] Further, the second limiting assembly includes a first limiting plate, a second limiting plate, and a connecting column; the first limiting plate and the second limiting plate are arranged opposite to each other and there is a distance between them, the connecting column is arranged between the first limiting plate and the second limiting plate, and one end of the connecting column is connected to the first limiting plate, and the other end is connected to the second limiting plate;

[0022] The first limit plate is arranged closer to the first limit assembly than the second limit plate; the first limit plate is formed as the second abutment portion; the driving assembly is drivingly connected to the second limit plate;

[0023] The distance from the end surface of the first limit plate facing the first limit assembly to the end surface of the second limit plate facing the first limit plate is greater than or equal to the distance from the end of the second rod structure away from the bottom of the second sub-pump assembly to the bottom of the second sub-pump assembly.

[0024] By adopting the above structure, the structure of the second limit assembly is more reasonable; the first limit plate is provided with the second avoidance perforation to facilitate the placement of the second sub-pump assembly, and the second limit plate is provided to facilitate the connection with the drive assembly, thereby solving the problem that the first limit plate cannot be well connected with the drive assembly due to the second avoidance perforation provided on the first limit plate; the setting of the connecting column connects the first limit plate and the second limit plate together so that they can move as a whole; the above structure enables the drive assembly to be connected to the axis of the second limit assembly, so that the drive assembly can drive the second limit assembly more smoothly; specifically, two connecting columns are provided, and the two connecting columns are symmetrically arranged on both sides of the first avoidance perforation, so that the connection between the first limit plate and the second limit plate is more reliable; the connecting column is connected to the first limit plate and the second limit plate by welding.

[0025] Furthermore, the first limiting assembly is detachably mounted on the guiding assembly.

[0026] The above structure is adopted to facilitate the user to place the first sub-pump assembly and the second sub-pump assembly on the first abutment portion; specifically, during use, the maintenance personnel can first remove the first limiting assembly from the guide assembly, at which time the first abutment portion is completely open to the side of the first abutment portion, and the maintenance personnel can more conveniently place the first sub-pump assembly and the second sub-pump assembly on the first abutment portion; then align the first avoidance perforation on the second limiting assembly with the first rod structure on the first sub-pump assembly and then install it on the guide assembly; since the first rod structure is relatively long, the above structure can also greatly reduce the distance required for the first abutment portion and the second abutment portion when the first sub-pump assembly and the second sub-pump assembly are in a pre-installed state, that is, when the two are relative but separated, and also greatly reduce the movement stroke required by the second limiting assembly, that is, greatly reduce the guide assembly; the above structure can make the design of the sub-pump maintenance tool more reasonable, greatly reduce the space required for the sub-pump maintenance tool, and at the same time make it more convenient and quick to use.

[0027] Furthermore, the slave cylinder repair tool comprises a limiter; the guide assembly comprises a slide rod; a coaxial limiter section is provided at one end of the slide rod; the limiter can be detachably fixedly mounted on the limiter section;

[0028] The first limiting component is provided with a first limiting component mounting hole, and the first limiting component mounting hole matches the slide bar to be sleeved on the slide bar, and the maximum distance between the outer side wall of the limiting member and the axis of the slide bar is greater than the radius of the first limiting component mounting hole;

[0029] Along the axis direction of the first avoidance through-hole, the limiting member and the second limiting assembly are respectively located on two sides of the first limiting assembly.

[0030] With the above structure, when in use, the maintenance personnel need to first remove the limit member from the limit section, at which point the maintenance personnel can remove the first limit member from the slide rod by moving the first limit member away from the second limit member; after the maintenance personnel place the first sub-pump assembly and the second sub-pump assembly on the second abutting portion, align the first avoidance through-hole with the first rod structure on the first sub-pump assembly, align the first limit member mounting hole with the slide rod and slide it toward the second limit member so that the first abutting portion abuts against the top of the first sub-pump assembly to complete the installation of the first limit member; at this point, the limit member is installed on the limit section, and the drive assembly drives the second limit member to move toward the first limit member side. If the first limit member does not abut against the limit member, the first limit member and the second limit member will move toward the limit member side as a whole until the first limit member abuts against the limit member, making it impossible for it to continue to move in this direction, and the second limit member continues to move close to the first limit member to achieve the installation of the first sub-pump assembly and the second sub-pump assembly;

[0031] The above structure enables the first limit assembly to be detachably mounted on the guide assembly, and has a simple structure, is easy to install, and is convenient for maintenance personnel to use.

[0032] Furthermore, the outer wall of the limiting section has an external thread; the limiting member is provided with a limiting member mounting hole matching the limiting section, and the inner wall of the limiting member mounting hole has an internal thread matching the external thread of the outer wall of the limiting section.

[0033] Specifically, the outer contour of the cross section of the limiting member is a regular polygon, and the diameter of the circumscribed circle of the outer contour of the cross section of the limiting member is larger than the aperture of the mounting hole of the first limiting assembly; more specifically, the limiting member adopts an octagonal nut.

[0034] With the above structure, the limiting member can be detachably mounted on the limiting segment and can maintain its position on the limiting segment through the cooperation of the internal thread on the limiting member and the external thread on the limiting segment. The above structure is simple and convenient for practical operation.

[0035] Furthermore, the diameter of the limiting section is smaller than the diameter of the mounting hole of the first limiting assembly.

[0036] By adopting the above structure, the structural setting of the limiting section is reasonable; since the diameter of the limiting section is smaller than the aperture of the mounting hole of the first limiting component, not only can maintenance personnel more conveniently align the mounting hole of the first limiting component with the limiting section when installing the first limiting component, and more conveniently insert the mounting hole of the first limiting component into the sliding rod through the limiting section; but also maintenance personnel can try to avoid contact between the inner wall of the mounting hole of the first limiting component and the external thread on the outer wall of the limiting section when disassembling and assembling the first limiting component, thereby reducing unnecessary accidental wear of the external thread on the limiting section, ensuring the installation reliability of the limiting member on the limiting section, and greatly extending the life of the limiting section.

[0037] Furthermore, two sliding rods are provided, and are symmetrically arranged on both sides of the axis of the second limiting assembly; correspondingly, the second limiting assembly is respectively provided with the sliding holes on both sides of the sliding rod, and the distance between the two sliding holes matches the distance between the two sliding rods, that is, the second limiting assembly is respectively provided with the sliding cylinder on both sides of the sliding rod, and the distance between the two sliding cylinders matches the distance between the two sliding rods.

[0038] By adopting the above structure, the structural setting of the guide assembly is more reasonable, the two slide bars can guide the movement of the second limit assembly more smoothly and reliably, and the two slide bars are matched with the two slide holes in a one-to-one correspondence, which can prevent the second limit assembly from rotating around one of the slide bars, making the installation of the second limit assembly more reliable, making the structure of the slave pump maintenance tool more reasonable, and being able to better complete the maintenance work of the slave pump;

[0039] Correspondingly, the first limit assembly is respectively provided with the first limit assembly mounting holes on both sides facing the sliding rod, and the distance between the two first limit assembly mounting holes matches the distance between the two sliding rods; in the above structure, the two first limit assembly mounting holes are matched with the two sliding rods one-to-one, which can avoid the first limit assembly from rotating around one of the sliding rods, making the installation of the first limit assembly more reliable.

[0040] Further, the second limiting assembly includes a first limiting plate and a second limiting plate; the first limiting plate and the second limiting plate are arranged opposite to each other and there is a distance between them; the slide cylinder is arranged on one side of the first limiting plate and the second limiting plate, and the end of the slide cylinder facing the first limiting plate is connected to the first limiting plate, and the end facing the second limiting plate is connected to the second limiting plate.

[0041] The above structure makes the structural setting of the second limit assembly more reasonable, and realizes the connection between the slide cylinder and the first limit plate and the second limit plate; specifically, the slide cylinder and the first limit plate and the second limit plate are connected and fixed by welding.

[0042] Further, the first limiting plate is provided with first side plates arranged at an angle to the first limiting plate on both sides along the width direction thereof, and the first side plates are bent and extended away from the first limiting assembly, that is, the second side plates are arranged on the long sides of the first limiting plate;

[0043] The second limiting plate is provided with second side plates arranged at an angle to the second limiting plate on both sides along the width direction thereof, and the second side plates are bent and extended away from the first limiting assembly, that is, the second side plates are arranged on the long sides of the second limiting plate;

[0045] With the above structure, since the first limit plate, the second limit plate, and the third limit plate have a certain length, the first side plate, the second side plate, and the third side plate are respectively set, which can greatly enhance the strength of the first limit plate, the second limit plate, and the third limit plate in the length direction, that is, it can reduce the possibility of bending of the first limit plate, the second limit plate, and the third limit plate in the length direction, thereby enhancing the reliability of the sub-pump maintenance tool and greatly extending its service life.

[0046] Specifically, the first side plate is perpendicular to the first limiting plate, and the first side plate and the first limiting plate are an integral part;

[0047] The second side plate is perpendicular to the second limiting plate, and the second side plate and the second limiting plate are an integral part;

[0048] The third side plate is perpendicular to the third limiting plate, and the third side plate and the third limiting plate are an integral part.

[0049] The above structure further enhances the strength of the first limit plate, the second limit plate and the third limit plate in the length direction, reduces the possibility of bending of the first limit plate, the second limit plate and the third limit plate in the length direction, enhances the reliability of the slave cylinder maintenance tool and greatly extends its service life.

[0050] Further, the first limiting assembly is located above the second limiting assembly, and the driving assembly is located below the second limiting assembly;

[0051] The driving assembly includes a jack, and the jack has a movable end capable of lifting a heavy object, and the movable end is connected to the bottom of the second limiting assembly.

[0052] The above structure makes the structure of the slave cylinder maintenance tool more reasonable, so that the jack can be used to drive the second limit assembly to move closer to or away from the first limit assembly.

[0053] Specifically, the jack adopts a hydraulic jack, and more specifically, the jack adopts a vertical hydraulic jack with a hand crank handle. The vertical hydraulic jack with a hand crank handle is a prior art, so the relevant structure and usage are not elaborated in detail.

[0054] Furthermore, the slave cylinder repair tool comprises a base, and the guide assembly and the drive assembly are arranged on the base.

[0055] The above structure makes the structure of the slave cylinder repair tool more reasonable. The guide assembly and the drive assembly are arranged on the base, which can facilitate maintenance personnel to move the entire slave cylinder repair tool for easy use.

[0056] Furthermore, the base includes a substrate and supporting feet. The top surface of the substrate is used to install the guide assembly and the drive assembly, and the bottom surface of the substrate is provided with the supporting feet.

[0057] Specifically, there are four supporting feet, which are respectively arranged at four corners of the bottom surface of the substrate.

[0058] The above structure makes the structural setting of the base more reasonable.

[0091] By adopting the above structure, the structure of the second limiting assembly 2 is more reasonable; the first limiting plate 205 is provided with the second avoidance through-hole 202 to facilitate the placement of the second sub-pump assembly B, and the second limiting plate 206 is provided to facilitate the connection with the driving assembly 4, so as to solve the problem that the first limiting plate 205 cannot be well connected with the driving assembly 4 due to the second avoidance through-hole 202; the setting of the connecting column 207 connects the first limiting plate 205 and the second limiting plate 206 together so that they can move as a whole; the above structure enables the driving assembly 4 to be connected to the axis of the second limiting assembly 2, so that the driving assembly 4 can drive the second limiting assembly 2 more smoothly; specifically, two connecting columns 207 are provided, and the two connecting columns 207 are symmetrically arranged on both sides of the first avoidance through-hole 102, so that the connection between the first limiting plate 205 and the second limiting plate 206 is more reliable; the connecting column 207 is connected to the first limiting plate 205 and the second limiting plate 206 by welding.

[0092] Furthermore, the first limiting component 1 is detachably mounted on the guiding component 3 .

[0093] The above structure is adopted to facilitate the user to place the first sub-pump assembly A and the second sub-pump assembly B on the first abutment portion 101; specifically, when in use, the maintenance personnel can first remove the first limit assembly 1 from the guide assembly 3, at which time the first abutment portion 101 is in a fully open state toward the side of the first abutment portion 101, and the maintenance personnel can more conveniently place the first sub-pump assembly A and the second sub-pump assembly B on the first abutment portion 101; then align the first avoidance through-hole 102 on the second limit assembly 2 with the first rod structure A01 on the first sub-pump assembly A and then install it on the guide assembly 3; since the first rod structure A01 is relatively long, the above structure can also greatly reduce the distance required between the first abutment portion 101 and the second abutment portion 201 when the first sub-pump assembly A and the second sub-pump assembly B are in a pre-installed state, that is, when the two are in a relative but separated state, and also greatly reduce the movement stroke required by the second limit assembly 2, that is, greatly reduce the guide assembly 3; the above structure can make the design of the sub-pump maintenance tool more reasonable, greatly reduce the space required for the sub-pump maintenance tool, and make it more convenient and quick to use.

[0094] Furthermore, the slave cylinder maintenance tool includes a limiter 5; the guide assembly 3 includes a slide bar 301; a coaxial limiter section 302 is provided at one end of the slide bar 301; the limiter 5 can be detachably fixedly mounted on the limiter section 302;

[0095] The first limiting component 1 is provided with a first limiting component mounting hole 103, and the first limiting component mounting hole 103 matches the slide bar 301 to be sleeved on the slide bar 301, and the maximum distance between the outer side wall of the limiting member 5 and the axis of the slide bar 301 is greater than the radius of the first limiting component mounting hole 103;

[0096] Along the axial direction of the first avoidance through hole 102 , the limiting member 5 and the second limiting assembly 2 are respectively located on two sides of the first limiting assembly 1 .

[0097] When using the above structure, the maintenance personnel need to first remove the limiting member 5 from the limiting section 302. At this time, the maintenance personnel can remove the first limiting component 1 from the slide bar 301 by moving the first limiting component 1 away from the second limiting component 2. When the maintenance personnel place the first sub-pump component A and the second sub-pump component B on the second abutment portion 201, the first avoidance through-hole 102 is aligned with the first rod structure A01 on the first sub-pump component A, and the first limiting component mounting hole 103 is aligned with the slide bar 301 and slides into the second limiting component 2 so that the first abutment portion 101 is aligned with the first sub-pump component A. The top of component A abuts to complete the installation of the first limiting component 1; at this time, the limiting member 5 is installed on the limiting section 302, and the driving component 4 drives the second limiting component 2 to move toward the first limiting component 1. If the first limiting component 1 does not abut against the limiting member 5, the first limiting component 1 and the second limiting component 2 will move toward the limiting member 5 as a whole until the first limiting component 1 abuts against the limiting member 5, making it impossible for them to continue to move in this direction, and the second limiting component 2 continues to move to approach the first limiting component 1, thereby realizing the installation of the first sub-pump component A and the second sub-pump component B;

[0098] The above structure enables the first limit assembly 1 to be detachably mounted on the guide assembly 3 , and has a simple structure, is easy to install, and is convenient for maintenance personnel to use.

[0099] Furthermore, the outer wall of the limiting section 302 has an external thread 3021 ; the limiting member 5 is provided with a limiting member mounting hole 501 matching the limiting section 302 , and the inner wall of the limiting member mounting hole 501 has an internal thread 5011 matching the external thread 3021 of the outer wall of the limiting section 302 .

[0100] Specifically, the outer contour of the cross section of the limiting member 5 is a regular polygon, and the diameter of the circumscribed circle of the outer contour of the cross section of the limiting member 5 is larger than the aperture of the first limiting assembly mounting hole 103; more specifically, the limiting member 5 adopts an octagonal nut.

[0101] By adopting the above structure, the limiting member 5 cooperates with the external thread 3021 on the limiting section 302 through the internal thread 5011 thereon, so that the limiting member 5 can be detachably installed on the limiting section 302 and can maintain its position on the limiting section 302; the above structure is simple and convenient for actual operation.

[0102] Furthermore, the diameter of the limiting section 302 is smaller than the aperture of the first limiting assembly mounting hole 103 .

[0103] By adopting the above structure, the structural setting of the limiting section 302 is reasonable; since the diameter of the limiting section 302 is smaller than the aperture of the first limiting component mounting hole 103, not only can the maintenance personnel more conveniently align the first limiting component mounting hole 103 with the limiting section 302 when installing the first limiting component 1, and more conveniently insert the first limiting component mounting hole 103 into the sliding rod 301 through the limiting section 302; but also the maintenance personnel can avoid the contact between the inner wall of the first limiting component mounting hole 103 and the external thread 3021 on the outer wall of the limiting section 302 as much as possible when disassembling and assembling the first limiting component 1, thereby reducing unnecessary accidental wear of the external thread 3021 on the limiting section 302, ensuring the installation reliability of the limiting member 5 on the limiting section 302, and greatly extending the life of the limiting section 302.

[0104] Furthermore, two sliding rods 301 are provided, and are symmetrically arranged on both sides of the axis of the second limiting component 2; correspondingly, the second limiting component 2 is respectively provided with the sliding holes 203 on both sides facing the sliding rod 301, and the distance between the two sliding holes 203 matches the distance between the two sliding rods 301, that is, the second limiting component 2 is respectively provided with the sliding cylinder 204 on both sides facing the sliding rod 301, and the distance between the two sliding cylinders 204 matches the distance between the two sliding rods 301.

[0105] By adopting the above structure, the structural setting of the guide assembly 3 is more reasonable, the two slide bars 301 can guide the movement of the second limit assembly 2 more smoothly and reliably, and the two slide bars 301 are matched with the two slide holes 203 in a one-to-one correspondence, which can prevent the second limit assembly 2 from rotating around a certain slide bar 301, making the installation of the second limit assembly 2 more reliable, making the structure of the slave pump maintenance tool more reasonable, and being able to better complete the maintenance work of the slave pump;

[0106] Correspondingly, the first limiting component 1 is respectively provided with the first limiting component mounting holes 103 on both sides facing the sliding rod 301, and the distance between the two first limiting component mounting holes 103 matches the distance between the two sliding rods 301; in the above structure, the two first limiting component mounting holes 103 are matched with the two sliding rods 301 one by one, which can avoid the first limiting component 1 from rotating around one of the sliding rods 301, making the installation of the first limiting component 1 more reliable.

[0107] Furthermore, the second limiting assembly 2 includes a first limiting plate 205 and a second limiting plate 206; the first limiting plate 205 and the second limiting plate 206 are arranged opposite to each other and there is a distance between them; the slide 204 is arranged on one side of the first limiting plate 205 and the second limiting plate 206, and the end of the slide 204 facing the first limiting plate 205 is connected to the first limiting plate 205, and the end facing the second limiting plate 206 is connected to the second limiting plate 206.

[0108] By adopting the above structure, the structural setting of the second limit assembly 2 is more reasonable; the connection between the slide 204 and the first limit plate 205 and the second limit plate 206 is realized; specifically, the slide 204 and the first limit plate 205 and the second limit plate 206 are connected and fixed by welding.

[0109] Further, the first limiting plate 205 is provided with first side plates 208 arranged at an angle to the first limiting plate 205 on both sides along the width direction thereof, and the first side plates 208 are bent and extended away from the first limiting assembly 1, that is, the second side plates 209 are arranged on the long sides of the first limiting plate 205;

[0110] The second limiting plate 206 is provided with second side plates 209 arranged at an angle to the second limiting plate 206 on both sides along the width direction thereof, and the second side plates 209 are bent and extended away from the first limiting assembly 1, that is, the second side plates 209 are arranged on the long sides of the second limiting plate 206;

[0111] The first limiting assembly 1 includes a third limiting plate 104, and the third limiting plate 104 is formed as the first abutting portion 101; the third limiting plate 104 is provided with third side plates 105 arranged at an angle to the third limiting plate 104 on both sides along its width direction, and the third side plate 105 is bent and extended toward the second limiting assembly 2, that is, the second side plate 209 is arranged on the long side of the third limiting plate 104; the first limiting assembly mounting hole 103 is arranged on the third limiting plate 104.

[0112] With the above structure, since the first limit plate 205, the second limit plate 206, and the third limit plate 104 have a certain length, the first side plate 208, the second side plate 209, and the third side plate 105 are respectively set, so that the strength of the first limit plate 205, the second limit plate 206, and the third limit plate 104 in the length direction can be greatly enhanced, that is, the possibility of the first limit plate 205, the second limit plate 206, and the third limit plate 104 bending in the length direction can be reduced, thereby enhancing the reliability of the sub-pump maintenance tool and greatly extending its service life.

[0113] Specifically, the first side plate 208 is perpendicular to the first limiting plate 205, and the first side plate 208 and the first limiting plate 205 are an integral part;

[0114] The second side plate 209 is perpendicular to the second limiting plate 206, and the second side plate 209 and the second limiting plate 206 are an integral part;

[0120] Specifically, the jack 401 is a hydraulic jack 401. More specifically, the jack 401 is a vertical hydraulic jack 401 with a hand crank handle. The vertical hydraulic jack 401 with a hand crank handle is a prior art, so the relevant structure and usage will not be elaborated in detail.
