Abstract

The present application relates to the technical field of electric power construction, in particular to a compression type strain clamp threading crimping bending correction device, which comprises a supporting mechanism and a correction pressure applying mechanism. By setting the retractable measuring point pressure head matched with the graduated indicating scale, when the sliding seat drives the correction pressure applying mechanism to move along the length direction of the supporting mechanism, the measuring point pressure head will be elastically attached to the outer periphery of the strain clamp. By observing the scale offset of the indicating scale relative to the reference observation groove, the deformation amount of the strain clamp at different positions can be directly and quantitatively read. Without manual subjective judgment, the maximum bending deformation position can be accurately locked, the positioning accuracy of the correction point is effectively improved, the problems of over-correction and under-correction caused by positioning deviation are avoided, and the overall straightness of the strain clamp after correction is ensured.

Description

Technical Field

[0001] This invention relates to the field of power construction technology, specifically to a compression-type tension clamp for wire threading and bending correction device. Background Technology

[0002] In overhead transmission lines, compression tension clamps are core components for conductor anchoring and splicing installation, widely used in the erection and maintenance of transmission lines of various voltage levels. During the crimping assembly process between the tension clamp and the conductor, uneven compression stress, assembly deviations, and equipment tooling errors can easily cause varying degrees of bending deformation. If bending defects cannot be effectively corrected, they will directly affect the coaxiality of conductor threading and the accuracy of line installation, and may also lead to abnormal stress on the line in later operation, seriously threatening the operational safety of the transmission line. In the prior art, the cited document with application number 202011618470.6 discloses a compression tension clamp threading and crimping bending correction device and its usage method. This solution integrates threading assistance and bending correction functions, abandoning the traditional rough correction mode of manual hammering, effectively reducing damage and strand breakage caused to the clamp body and conductor structure by manual operation, greatly improving the convenience of tension clamp correction operations, and optimizing the shaping operation conditions after tension clamp crimping to a certain extent.

[0003] However, the correction device disclosed in the cited document has significant technical flaws in actual field operation. The device relies entirely on the operator's subjective visual observation to determine the bending deformation area of ​​the tension clamp and identify the points requiring correction. While the naked eye can roughly identify the deformation location for large-angle, significant bending defects in the clamp, tension clamps, after crimping, often exhibit only minute bending deformation under most operating conditions. This deformation is small and the differences are subtle, making visual identification extremely difficult. Relying solely on visual observation cannot accurately distinguish the overall deformation distribution, let alone quickly and accurately pinpoint the clamp's maximum deformation location. Because the correction reference point relies on blind visual judgment, it is highly susceptible to misalignment of the correction pressure position, leading to over-correction, under-correction, or localized correction. Uneven stress distribution makes it impossible to guarantee the overall straightness and crimping quality of tension clamps. Furthermore, misalignment correction can generate residual stress inside the clamps, which, when exposed to complex outdoor conditions such as wind vibration, temperature differences, and heavy loads, can easily lead to safety hazards such as clamp cracking, contact surface wear, and partial discharge of the line. In addition, manual visual judgment is highly subjective and lacks standardized quantitative criteria, resulting in significant errors in observation and judgment among different operators. This leads to inconsistent quality in the correction work and makes it difficult to meet the quality control requirements of refined and standardized construction of high-voltage transmission lines. Therefore, to address the core problems of existing correction devices relying on visual positioning, difficulty in identifying minute deformations, and insufficient accuracy of correction points, and to overcome the operational shortcomings of existing technologies, this paper proposes a compression-type tension clamp crimping bending correction device for threading. Summary of the Invention

[0004] The purpose of this invention is to provide a crimping bending correction device for threading compression tension clamps, so as to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compression-type tension clamp for threading wire, comprising:

[0006] A support mechanism and a corrective pressure mechanism, wherein the corrective pressure mechanism is movable along the length of the support mechanism, and the corrective pressure mechanism includes:

[0007] The sliding seat is slidably connected to the support mechanism.

[0008] The second adjusting screw hole runs through the interior of the sliding seat from top to bottom.

[0009] The adjusting screw is threaded into the second adjusting screw hole.

[0010] The pressure seat is fixedly installed at the bottom of the adjusting screw and can rotate relative to the adjusting screw;

[0011] The measuring pressure head is movable and positioned at the bottom of the pressure base along the height direction of the pressure base.

[0012] An indicator ruler is fixedly installed on the top of the measuring point pressure head, with one end bent vertically upwards. The upward-bent part of the indicator ruler has graduations.

[0013] The reference observation slot is located on the side of the pressure seat that is close to the upward bend of the indicator scale, and in the initial state, the reference observation slot corresponds to the zero mark position of the indicator scale.

[0014] As a preferred embodiment of the present invention, the support mechanism includes a support base body and two limiting blocks. The support base body has slots at both ends, and the two limiting blocks are respectively fixedly disposed inside the two slots. A through hole is formed through the opposite surfaces of the two limiting blocks. Two adjusting screw holes are horizontally formed on the inner wall of the through hole. The two adjusting screw holes are symmetrical about the center of the through hole, and wing bolts are threaded inside the two adjusting screw holes. A sliding guide groove is formed through the top of the support base body, and the sliding seat is slidably disposed inside the sliding guide groove.

[0015] As a preferred embodiment of the present invention, the top of the pressure seat is provided with a plurality of buffer guide holes extending downward, and a buffer guide rod is slidably disposed inside each of the plurality of buffer guide holes. The bottom of the buffer guide rod is fixed together with the top of the measuring point pressure head. A buffer spring is sleeved around the buffer guide rod. The bottom of the buffer spring is fixed with the top of the measuring point pressure head, and its top is fixed with the inner end face of the sinking groove of the adjusting screw.

[0016] As a preferred embodiment of the present invention, both ends of the top of the sliding seat are provided with guide holes extending downwards, and a linear bearing is fixedly installed inside the guide hole. A guide rod is slidably installed inside the linear bearing, and the bottom of the guide rod is fixed to the top of the pressure seat.

[0017] As a preferred embodiment of the present invention, a positioning block is movably provided on the top of the pressure seat along its height direction, the buffer guide rod moves through the positioning block, and two guide sliding holes are opened downward through the top of the positioning block. The inner wall of the guide sliding hole slides in cooperation with the outer wall of the guide rod. A positioning tooth is provided on the top of the positioning block, and a positioning tooth groove is provided on the bottom of the support body. The positioning tooth groove and the positioning tooth are matched in specifications. A return spring is sleeved around the guide rod, and the return spring is fixedly disposed between the top of the positioning block and the bottom of the sliding seat.

[0018] As a preferred embodiment of the present invention, the top of the positioning block has two first magnetic grooves, which are located between two guide rods, and a first magnetic block is fixedly disposed inside each of the two first magnetic grooves. The top of the pressure seat has two second magnetic grooves, the positions of the second magnetic grooves correspond one-to-one with the positions of the first magnetic grooves, and a second magnetic block is fixedly disposed inside each of the second magnetic grooves. The second magnetic block has opposite magnetism to the first magnetic block. In the initial state, the top of the second magnetic block attracts the bottom of the first magnetic block, so that the positioning block drives the positioning teeth to move downward and disengage from the positioning tooth groove.

[0019] As a preferred embodiment of the present invention, the sliding seat is provided with locking screw holes on both sides near the two guide holes, and locking bolts are provided inside the locking screw holes. The ends of the locking bolts press against the outer ring surface of the linear bearing. The positioning block is fixedly provided with a limiting sheet metal on one side near one of the locking bolts. A limiting groove is provided on the limiting sheet metal. In the initial state, the top wall of the limiting groove abuts against the outer wall of the locking bolt.

[0020] As a preferred embodiment of the present invention, a rotating handle is fixedly provided on the top of the adjusting screw, and the rotating handle is used to drive the adjusting screw to rotate.

[0022] As a preferred embodiment of the present invention, a through cavity is provided at the top center of the positioning block to accommodate the passage of the adjusting screw, the inner diameter of the through cavity being larger than the outer diameter of the adjusting screw, and a bearing mounting cavity is provided at the top center of the pressure seat, the adjusting screw being rotatably mounted inside the bearing mounting cavity via the bearing.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By setting a retractable measuring head in conjunction with a graduated indicator, when the sliding seat drives the entire straightening and pressing mechanism to move along the length of the support mechanism, the measuring head will elastically fit against the outer periphery of the tension clamp. By observing the offset of the indicator scale relative to the reference observation groove, the deformation of the tension clamp at different positions can be read intuitively and quantitatively. The position of maximum bending deformation can be accurately locked without the need for subjective judgment by the naked eye, which effectively improves the positioning accuracy of the straightening point and avoids the problems of over-correction and under-correction caused by positioning deviation, thus ensuring the overall straightness of the tension clamp after correction.

[0025] 2. By setting up a matching structure between the positioning block and the positioning tooth groove, when the correction and pressure mechanism moves into place, rotating the adjusting screw drives the pressure seat to move down as a whole. The first magnetic block and the second magnetic block disengage, and the reset spring pushes the positioning block up, so that the positioning tooth automatically engages with the positioning tooth groove to complete the positioning and locking. The position of the sliding seat can be fixed without additional manual operation, which improves the convenience of operation. At the same time, it ensures that the sliding seat will not move during the correction and pressure process, further improving the correction accuracy. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-9 The technical solution provided by the present invention specifically includes the following embodiments:

[0038] A compression-type tension clamp for threading wires includes a support mechanism 100 and a straightening and pressing mechanism 200. The straightening and pressing mechanism 200 is movable along the length of the support mechanism 100. The support mechanism 100 includes a support base body 101 and two limiting blocks 103. The support base body 101 has slots 102 at both ends. The two limiting blocks 103 are fixedly installed in the two slots 102. The two limiting blocks 103 have threaded holes 104 through their opposite surfaces. The inner wall of the threaded hole 104 has two horizontally opened adjusting screw holes 105. The two adjusting screw holes 105 are symmetrical about the center of the threaded hole 104, and each adjusting screw hole 105 is threaded with a wing bolt 106. The top of the support base body 101 has a downwardly extending sliding guide groove 107 through which a sliding seat 201 is slidably installed. By inserting both ends of the tension clamp to be corrected into the wire holes 104 in the limiting blocks 103 at both ends of the support body 101, and then rotating the wing bolts 106 in the two adjusting screw holes 105, the ends of the wing bolts 106 are pressed and fixed from both sides to secure the tension clamp. This completes the clamping and positioning of the tension clamp before correction. After clamping, the tension clamp is located inside the support body 101 and extends along the length of the support body 101, providing a stable reference for subsequent deformation detection and correction operations. Then, the tension clamp is corrected by the correction pressure mechanism 200.

[0039] For further details, please refer to [link / reference]. Figures 3-9 As shown:

[0040] The correction pressure mechanism 200 includes a sliding seat 201, which is slidably connected to the support mechanism 100. An adjustment screw hole 202 extends from top to bottom through the sliding seat 201. An adjustment screw rod 203 is threaded into the adjustment screw hole 202. A pressure seat 204 is fixedly mounted at the bottom of the adjustment screw rod 203, and the pressure seat 204 and the adjustment screw rod 203 are rotatable relative to each other. A measuring pressure head 205 is movably mounted at the bottom of the pressure seat 204 along its height direction. An indicator ruler 206 is fixedly mounted at the top of the measuring pressure head 205. One end of the indicator ruler 206 is bent vertically upwards, and the bent portion has graduations. A reference observation groove 207 is provided on the side of the pressure seat 204 near the bent side of the indicator ruler 206. In the initial state, the reference observation groove 207... Corresponding to the zero mark position of the indicator ruler 206, the top of the pressure seat 204 has several buffer guide holes 2023 extending downwards. Buffer guide rods 2021 are slidably installed inside each of the buffer guide holes 2023. The bottom of the buffer guide rods 2021 is fixed together with the top of the measuring point pressure head 205. Buffer springs 2022 are sleeved around the buffer guide rods 2021. The bottom of the buffer springs 2022 is fixed to the top of the measuring point pressure head 205, and its top is fixed to the inner end face of the sinking groove of the adjusting screw 203. A handle 2028 is fixedly installed on the top of the adjusting screw 203. The handle 2028 is used to drive the adjusting screw 203 to rotate. A bearing mounting cavity 2020 is opened at the center of the top of the pressure seat 204. The adjusting screw 203 is rotatably installed inside the bearing mounting cavity 2020 through the bearing.The tension clamp is placed inside the two threading holes 104. Then, the tension clamp is manually rotated inside the two threading holes 104. As the tension clamp bends and deforms, rotating upwards, the bent part pushes upwards against the measuring pressure head 205, causing the measuring pressure head 205 to move upwards along the height of the pressure base 204. The measuring pressure head 205 drives the indicator scale 206 to move upwards synchronously. At this time, the corresponding scale positions of the reference observation slot 207 and the indicator scale 206 change accordingly. The operator can directly obtain the deformation magnitude at that position through the scale reading corresponding to the reference observation slot 207. When the tension clamp... After the clamp rotates one full turn, the operator records the maximum value of the scale reading corresponding to the reference observation slot 207. Then, the operator rotates the tension clamp again. When the value of the upward movement of the indicator scale 206 corresponding to the reference observation slot 207 coincides with the maximum value corresponding to the previous rotation, the rotation is stopped, and each wing bolt 106 is rotated to clamp and fix the tension clamp. At this point, the maximum deformation point of the bending protrusion is exactly facing the measuring pressure head 205. Next, the sliding seat 201 is manually moved to the other end of the positioning tooth groove 108. During this process, the measuring pressure head 205 moves along with the sliding seat 201. As the tension clamp moves, the measuring pressure head 205 slides along the top of the fixed tension clamp. During this process, the scale of the indicator 206 corresponding to the reference observation groove 207 generates a maximum value again, and the measuring pressure head 205 is aligned with the maximum bending deformation point of the tension clamp. Then, the sliding seat 201 is manually driven to slide in the opposite direction along the positioning groove 108. When the sliding seat 201 slides in the opposite direction until the measuring pressure head 205 is aligned with the maximum scale again, the movement stops. Then, the sliding seat 201 is initially fixed by hand to prevent it from moving relative to the positioning groove 108 again. Afterwards, the movement is accelerated by rotating the handle 2028. When the adjusting screw 203 rotates, it screws downwards along the inside of the adjusting screw hole 202, pushing the pressure seat 204 downwards as a whole. During this process, the pressure seat 204 gradually approaches the measuring pressure head 205, and the buffer spring 2022 is compressed until the bottom of the pressure seat 204 contacts the top of the measuring pressure head 205, pushing the measuring pressure head 205 downwards. The measuring pressure head 205 then applies corrective pressure downwards to the maximum deformation point of the tension clamp, completing the precise correction of the bent part. During the correction process, the indicator ruler 206 gradually falls back as the tension clamp bends and corrects.

[0041] For further details, please refer to [link / reference]. Figure 7 , Figure 8 , Figure 9 As shown:

[0042] The top of the pressure seat 204 has several downward-through buffer guide holes 2023. Buffer guide rods 2021 are slidably installed inside each of the buffer guide holes 2023. The bottom of the buffer guide rods 2021 is fixed together with the top of the measuring point pressure head 205. Buffer springs 2022 are sleeved around the buffer guide rods 2021. The bottom of the buffer springs 2022 is fixed to the top of the measuring point pressure head 205, and its top is fixed to the inner end face of the sinking groove of the adjusting screw 203. Both ends of the top of the sliding seat 201 have downward-through guide holes 2015. Linear bearings 2016 are fixedly installed inside each of the guide holes 2015. Guide rods 2017 are slidably installed inside each of the linear bearings 2016. The bottom of each guide rod 2017 is fixed to the top of the pressure seat 204. During the rotation of the tension clamp, the measuring pressure head 205 is pushed upward by its bending point. The measuring pressure head 205 pushes the buffer guide rod 2021 to slide upward along the corresponding buffer guide hole 2023. At the same time, the buffer spring 2022 is compressed, ensuring that the measuring pressure head 205 is always subjected to a downward reset force, so that the bottom of the measuring pressure head 205 can always be in contact with the outer ring surface of the tension clamp. During the downward movement of the pressure seat 204, the two linear bearings 2016 slide outside the corresponding guide rods 2017, which plays a stabilizing guiding role in the lifting and lowering movement of the pressure seat 204, preventing the pressure seat 204 from deflecting or shifting during the pressure application process, ensuring that the correction pressure direction is always perpendicular to the axis of the tension clamp, and improving the stability and accuracy of the correction pressure.

[0043] For further details, please refer to [link / reference]. Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown:

[0044] A positioning block 208 is movably mounted on the top of the pressure seat 204 along its height direction. A buffer guide rod 2021 movably passes through the positioning block 208. A through cavity 2019 is provided at the center of the top of the positioning block 208 to accommodate the passage of the adjusting screw 203. The inner diameter of the through cavity 2019 is larger than the outer diameter of the adjusting screw 203. Two guide sliding holes 2018 are provided downward through the top of the positioning block 208. The inner wall of the guide sliding holes 2018 slides in cooperation with the outer wall of the guide rod 2017. The support body 101 has a positioning tooth 209 and a positioning tooth groove 108 at its bottom. The positioning tooth groove 108 is compatible with the positioning tooth 209. A return spring 2010 is sleeved around the guide rod 2017. The return spring 2010 is fixedly installed between the top of the positioning block 208 and the bottom of the sliding seat 201. The top of the positioning block 208 has two first magnetic grooves 2011. The two first magnetic grooves 2011 are located between the two guide rods 2017, and each of the two first magnetic grooves 2011 is fixedly installed inside. There is a first magnetic block 2012, and two second magnetic grooves 2013 are formed on the top of the pressure base 204. The positions of the second magnetic grooves 2013 correspond one-to-one with the positions of the first magnetic grooves 2011, and a second magnetic block 2014 is fixedly installed inside each of the second magnetic grooves 2013. The second magnetic block 2014 has opposite magnetism to the first magnetic block 2012. In the initial state, the top of the second magnetic block 2014 is attracted to the bottom of the first magnetic block 2012, so that the positioning block 208 drives the positioning tooth 209 to move downward and disengage from the positioning tooth groove 108. The sliding seat 201 has locking screw holes 2024 on both sides near the two guide holes 2015. Locking bolts 2025 are threaded inside the locking screw holes 2024. The ends of the locking bolts 2025 press against the outer ring surface of the linear bearing 2016. The positioning block 208 is fixedly provided with a limiting sheet metal 2026 near one of the locking bolts 2025. A limiting groove 2027 is provided on the limiting sheet metal 2026. In the initial state, the top wall of the limiting groove 2027 abuts against the outer wall of the locking bolt 2025.As the pressure seat 204 moves downward, it also simultaneously drives the two second magnetic blocks 2014 to move. However, the positioning block 208 is prevented from moving downward due to the resistance of the limiting groove 2027 and the locking bolt 2025. This causes the second magnetic blocks 2014 to disengage from the first magnetic block 2012 during their downward movement. Once the second magnetic blocks 2014 and the first magnetic blocks 2012 are completely separated, the spring force of the return spring 2010 pushes the positioning block 208 upward, causing the positioning teeth 209 at the top of the positioning block 208 to quickly engage with the positioning tooth groove 108. The positioning teeth 209 and the positioning tooth groove 108 then engage. The engagement of 08 locks the current position of the sliding seat 201, preventing accidental sliding of the sliding seat 201 during the correction pressure process and thus avoiding deviation of the correction point, further ensuring the correction accuracy. After the correction is completed, the reverse rotation of the handle 2028 drives the adjusting screw 203 to reset. The adjusting screw 203 drives the pressure seat 204 to move upward and reset. The second magnetic block 2014 re-engages with the first magnetic block 2012, driving the positioning block 208 to move downward and reset, so that the positioning tooth 209 disengages from the positioning tooth groove 108, releasing the position lock of the sliding seat 201. The correction position can then be readjusted, and the next correction operation can be carried out.

[0045] For further details, please refer to [link / reference]. Figure 2 , Figure 5 As shown:

[0046] The support body 101 has guide grooves 109 on both its front and back sides. The guide grooves 109 are connected to the positioning tooth grooves 108. Two guide wheels 2029 are rotatably mounted on each side of the sliding seat 201 near the two guide grooves 109. The guide wheels 2029 slide within the guide grooves 109. When the sliding seat 201 slides along the sliding guide groove 107 to adjust its position, the four guide wheels 2029 slide along the inner walls of their respective guide grooves 109. This not only limits the sliding stroke of the sliding seat 201, preventing it from detaching from the sliding guide groove 107, but also guides the sliding direction of the sliding seat 201 through the guide grooves 109, further improving the stability of the sliding process.

[0047] The working principle of a compression-type tension clamp bending correction device for threading wires, as described in this solution, is as follows:

[0048] The tension clamp is placed inside the two threading holes 104. Then, the tension clamp is manually rotated inside the two threading holes 104. As the tension clamp bends and deforms, rotating upwards, the bent part pushes upwards against the measuring pressure head 205, causing the measuring pressure head 205 to move upwards along the height of the pressure base 204. The measuring pressure head 205 drives the indicator scale 206 to move upwards synchronously. At this time, the corresponding scale positions of the reference observation slot 207 and the indicator scale 206 change accordingly. The operator can directly obtain the deformation magnitude at that position through the scale reading corresponding to the reference observation slot 207. When the tension clamp... After the clamp rotates one full turn, the operator records the maximum value of the scale reading corresponding to the reference observation slot 207. Then, the operator rotates the tension clamp again. When the value of the upward movement of the indicator scale 206 corresponding to the reference observation slot 207 coincides with the maximum value corresponding to the previous rotation, the rotation is stopped, and each wing bolt 106 is rotated to clamp and fix the tension clamp. At this point, the maximum deformation point of the bending protrusion is exactly facing the measuring pressure head 205. Next, the sliding seat 201 is manually moved to the other end of the positioning tooth groove 108. During this process, the measuring pressure head 205 moves along with the sliding seat 201. As the tension clamp moves, the measuring pressure head 205 slides along the top of the fixed tension clamp. During this process, the scale of the indicator 206 corresponding to the reference observation groove 207 generates a maximum value again, and the measuring pressure head 205 is aligned with the maximum bending deformation point of the tension clamp. Then, the sliding seat 201 is manually driven to slide in the opposite direction along the positioning groove 108. When the sliding seat 201 slides in the opposite direction until the measuring pressure head 205 is aligned with the maximum scale again, the movement stops. Then, the sliding seat 201 is initially fixed by hand to prevent it from moving relative to the positioning groove 108 again. Afterwards, the movement is accelerated by rotating the handle 2028. When the adjusting screw 203 rotates, it screws downwards along the inside of the adjusting screw hole 202, pushing the pressure seat 204 to move downwards as a whole. During this process, the pressure seat 204 gradually approaches the measuring pressure head 205, and the buffer spring 2022 is compressed until the bottom of the pressure seat 204 contacts the top of the measuring pressure head 205, pushing the measuring pressure head 205 downwards. The measuring pressure head 205 then applies corrective pressure downwards to the maximum deformation point of the tension clamp, completing the precise correction of the bent part. During the correction process, the indicator ruler 206 gradually falls back as the tension clamp bends and corrects.

[0049] As the pressure seat 204 moves downward, it also simultaneously drives the two second magnetic blocks 2014 to move. However, the positioning block 208 is prevented from moving downward due to the resistance of the limiting groove 2027 and the locking bolt 2025. This causes the second magnetic blocks 2014 to disengage from the first magnetic block 2012 during their downward movement. Once the second magnetic blocks 2014 and the first magnetic blocks 2012 are completely separated, the spring force of the return spring 2010 pushes the positioning block 208 upward, causing the positioning teeth 209 at the top of the positioning block 208 to quickly engage with the positioning tooth groove 108. The positioning teeth 209 and the positioning tooth groove 108 then engage. The engagement of 08 locks the current position of the sliding seat 201, preventing accidental sliding of the sliding seat 201 during the correction pressure process and thus avoiding deviation of the correction point, further ensuring the correction accuracy. After the correction is completed, the reverse rotation of the handle 2028 drives the adjusting screw 203 to reset. The adjusting screw 203 drives the pressure seat 204 to move upward and reset. The second magnetic block 2014 re-engages with the first magnetic block 2012, driving the positioning block 208 to move downward and reset, so that the positioning tooth 209 disengages from the positioning tooth groove 108, releasing the position lock of the sliding seat 201.
