Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a self-compensating J-type wire clamp installer. Background Art

[0002] The J-type wire clamp is a non-load-bearing wire clamp used to connect the secondary line of the branch line of a 10kV power line to the main line of the main line. Figure 1 As shown, it includes two J-shaped guide blocks that are engaged with each other and a tensioning bolt that guides the two guide blocks to produce similar movements. During installation, the branch line's secondary line is embedded in the wire groove of one guide block, and the main line of the main line is embedded in the wire groove of the other guide block; the two guide blocks are tightened by the cooperation of the tensioning bolt and the tensioning nut, so that the secondary line and the main line are tightly clamped on the guide blocks, thereby realizing the current connection and guidance functions through the guide blocks. At present, the installation of the J-type wire clamp has gradually been semi-automated, and its installation process includes: the operator stands under the main line, and manually fixes the J-type wire clamp and the secondary line on the wire clamp installer, and then hooks the J-type wire clamp on the main line through the wire clamp installer; then, the striking part automatically tightens the tensioning bolt or the tensioning nut at the J-type wire clamp, so that the two guide blocks of the J-type wire clamp produce mutually opposite movements, so as to realize the simultaneous tightening function of the J-type wire clamp relative to the branch line and the main line; finally, the wire clamp installer and the J-type wire clamp are separated, and the whole installation process is completed. However, during the above installation process, people found that: because the screw sleeve at the striking part of the traditional wire clamp installer is directly driven by the striking motor and produces a rotating motion, it only has a rotating motion around its own axis. When the screw sleeve engages with the tightening nut and rotates the tightening nut, the two guide blocks move relative to each other during the clamping process, and at the same time the tightening nut rotates upward along the tightening bolt, and in this process the tightening nut will gradually detach from the screw sleeve, resulting in incomplete contact between the screw sleeve and the tightening nut. The above incomplete contact phenomenon, at the least, makes the assembly process of the J-type wire clamp inefficient, and requires frequent starting and stopping of the striking motor to ensure that the tightening nut produces a rotating motion; at the worst, the screw sleeve cannot continue to drive the tightening nut, resulting in low clamping force of the wire clamp or even failure of the groove connection. Once the above situation occurs, the operator has to manually perform troubleshooting at high altitude, which is extremely time-consuming and labor-intensive, which obviously brings great trouble to the actual wire clamp groove connection operation. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a self-compensating J-type wire clamp installer so as to provide a basic working platform for the online wire clamp installation operation under aerial work; the present invention can make the J-type wire clamp in the process of parallel installation, the threaded sleeve always moves synchronously with the tightening nut or the nut of the tightening screw until the wire clamp is completely paralleled and clamped, thereby greatly improving the safety of use of the wire clamp and the actual installation efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A self-compensating J-type wire clamp installer, comprising a positioning and mounting portion for placing the wire clamp, a striking portion for tightening an object to be rotated, the striking portion comprising a screw sleeve coaxially arranged with the object to be rotated, the screw sleeve being driven by a striking motor to generate a coaxial rotational motion relative to the object to be rotated; the characteristic is that: the installer also includes a compensation component for driving the screw sleeve to generate an axially similar motion relative to the object to be rotated while the screw sleeve generates a rotational motion; the compensation component includes a transmission shaft coaxially fixed to the output shaft of the striking motor, an outer coaxial sleeve of the transmission shaft is provided with an outer guide sleeve, and a rotation-stopping fit is formed between the outer guide sleeve and the transmission shaft, and the screw sleeve is coaxially assembled on the top end of the outer guide sleeve; the compensation component also includes an elastic member for driving the outer guide sleeve to generate an axial upward motion relative to the transmission shaft.

[0006] Preferably, the elastic member is a lifting compression spring, which is sleeved on the transmission shaft, and the top end of the elastic member extends upward and presses against the bottom end surface of the outer guide sleeve, and the bottom end of the elastic member extends downward and presses against the driving end of the striking motor.

[0007] Preferably, the transmission shaft is a square shaft, and the sleeve cavity shape of the outer guide sleeve is adapted to the outer wall shape of the transmission shaft, so that the two form a spline-type anti-rotation fitting relationship.

[0008] Preferably, an annular protrusion is coaxially provided at the top end of the outer guide sleeve, and a locking tongue is arranged on one side of the outer guide sleeve for limiting the axial upward movement of the outer guide sleeve, and the locking tongue is controlled by the power member to produce radial reciprocating linear movement relative to the outer guide sleeve; when the outer guide sleeve is in a low initial position, the locking tongue extends and is located above the annular protrusion, thereby forming a one-way stop fit with the annular protrusion; when the outer guide sleeve is in a high working position, the locking tongue retracts under the control of the power member, and the outer guide sleeve produces an axial lifting movement under the action of the elastic member.

[0009] Preferably, the power part is an electromagnet, and the lock tongue and the power part are connected to each other through a return spring, so that when the power part is started, the return spring is compressed to drive the lock tongue to retract; the upper corner end of the top of the lock tongue is chamfered so that when the annular protrusion moves downward, the return spring is pressed to produce a compressed action.

[0010] Preferably, the sleeve cavity of the screw sleeve matches the top diameter of the outer guide sleeve, and the stopper of the bottom end surface of the screw sleeve fits on the upper shoulder of the outer guide sleeve from top to bottom, and the screw sleeve and the outer guide sleeve are fixedly connected by a set screw.

[0011] The beneficial effects of the present invention are:

[0012] 1) On the basis of the traditional rotary screwing of the object to be rotated, the present invention further provides an axial compensation component, thereby achieving the purpose of the compound action of "rotation + axial movement" of the screw sleeve. Because every time the screw sleeve twists the tightening nut or even the screw sleeve at the tightening screw, the threaded action of the tightening nut and the tightening screw sleeve will drive the two to produce similar actions, and at this time the object to be rotated located in the screw sleeve will also produce axial movement. Through the above-mentioned compound action of the screw sleeve, the present invention, whenever the object to be rotated travels a certain distance, the screw sleeve will produce compensatory action, that is, it will travel a certain distance synchronously, so as to always ensure that the object to be rotated is reliably located in the screw sleeve and forms a stable fit with the thread teeth at the screw sleeve, and finally ensure the reliable assembly effect of the screw sleeve relative to the J-type wire clamp.

[0013] In summary, the present invention can provide a basic working platform for the online wire clamp installation operation under high-altitude operation; the present invention can make the J-type wire clamp in the process of parallel installation, the thread sleeve always moves synchronously with the tightening nut or the tightening screw nut until the wire clamp is completely parallel and clamped, which greatly improves the safety of use and the actual installation efficiency of the wire clamp. When necessary, the present invention can be fully applied in the high-altitude remote sensing operation environment, that is, it can serve the online remote sensing technology, so as to minimize the human error. At the same time, the operator can stay away from the on-site environment and perform remote sensing operations through the display screen, and finally further improve the safety and efficiency of the actual operation.

[0014] 2) The compensation component can be implemented in a variety of ways, such as using a piston cylinder installed under the striking part. When the striking part rotates and drives the screw sleeve to produce a rotary motion, the piston cylinder produces a lifting motion to push the screw sleeve to produce an axial upward motion; or the striking part can be driven to produce the above-mentioned upward motion by means of a gear rack or even a crank slider. As a further preferred embodiment of the above scheme, the compensation component of the present invention is integrated in the striking part, thereby ensuring the compactness of the overall structure as much as possible, and is particularly suitable for use in high-altitude working environments with extremely high requirements on volume and weight. Specifically, the compensation component is integrated with the striking part through a transmission shaft, and the use state of the compensation component is ensured by an external guide sleeve and a lifting compression spring, and finally the established screw sleeve action purpose is achieved simply and reliably.

[0015] 3) The arrangement of the annular protrusion, on the one hand, is to form a shaft shoulder to fix and locate the position of the screw sleeve; on the other hand, it is to form a lock mouth, so as to cooperate with the lock tongue to achieve the self-reset and self-locking effect of the screw sleeve position. When it is necessary to twist the object to be rotated, the lock tongue retracts under the drive of the electromagnet. At this time, there is no obstruction above the annular protrusion, and the outer guide sleeve produces an axial upward action under the action of the lifting pressure spring, that is, the "rotation + axial upward" compound action of the screw sleeve is realized. When the assembly is completed, the screw sleeve needs to be reset for the next assembly; at this time, it is only necessary to press down the screw sleeve, and the screw sleeve and the annular protrusion go down together and press the lock tongue, and the lock tongue presses the reset pressure spring and produces a retraction action; after the annular protrusion passes over the lock tongue, the lock tongue will re-extend under the action of the reset pressure spring, that is, the locking action of the outer guide sleeve and even the screw sleeve is realized. Obviously, the above-mentioned whole set of processes is simple and reliable, and the number of components required is extremely low, which can meet the operation requirements of compact workpieces with few components and small volume.

[0042] For ease of understanding, here we combine Figure 1-14 Taking the installation and construction of a traditional J-type wire clamp as an example, hereinafter collectively referred to as a wire clamp, the specific structure and working method of the present invention are further described as follows:

[0043] The present invention can be used in remote control equipment such as robots; during actual assembly, the present invention can be fixed on a mechanical arm. At this time, since the main line is fixed as a reference object, the present invention can be completely lifted by the mechanical arm to complete the top-up wire clamp and groove operation relative to the main line. The traditional wire clamp installation method is to hook from top to bottom relative to the main line. The present invention adopts the opposite method of top-up installation relative to the main line. There is no need to make a crossing action during operation, so the complexity of the mechanical arm movement can be significantly reduced, which is convenient for the mechanical arm to dock with the main line operation, and is also more conducive to the use of high-altitude remote sensing robots.

[0044] Before actual installation, Figure 1 The conventional wire clamp shown in the figure is modified, that is, a screw is driven into the side of the upper guide block a as shown in 2, so as to form a positioning anchor column g. Of course, in actual operation, the positioning anchor column g can also be formed by driving a rivet or welding a column. The position of the positioning anchor column g should correspond to the position of the slide groove 13a at the positioning installation part 10, so as to facilitate later installation.

[0045] When the present invention actually works, its specific structure is as follows Figure 3-13 As shown, its main structure includes a positioning and mounting portion 10 for fixing the wire clamp, a secondary wire locking clamp 40 for fixing the secondary wire B, and a main wire guide clamp 30 for loading the main wire A. When the main wire and the secondary wire are installed in place relative to the wire clamp, the striking portion with the compensation component 23 is used to realize the lifting and rotating function of the tightening nut d, and finally the wire clamp, the main wire A, and the secondary wire B are tightly fixed to each other.

[0046] Of course, the present invention can also be applied to a down-hung type installation device as an additional component, such as Fig.14 As shown, the working purpose can be achieved.

[0047] For the convenience of description, the top-type wire clamp installation structure is still taken as an example for the following description:

[0048] 1. Positioning and mounting part 10

[0049] The positioning and mounting portion 10 has an appearance as follows Figure 3-7 and Figure 10-13 As shown, it comprises a base 11, two clamping rods 12 or clamping plates extending upward from the base 11, and a positioning assembly 13. The two clamping rods 12 are arranged parallel to each other, and a slide groove 13a is arranged on one or both inner sides of the adjacent surfaces, so as to provide Figure 2 The anchor column g is inserted into the wire clamp shown in the figure; the inserted state is as shown in the figure. Figure 6As shown in the figure, since the present invention adopts the top-up assembly method, when the striking part 20 strikes upward from the bottom, it is preferred to ensure that the upper guide block a is in a fixed state, so that the striking part 20 with a self-compensation function can screw the tightening nut d and drive the tightening nut d and even the lower guide block b to produce an upward movement relative to the upper guide block a.

[0050] When the upper guide block a is required to be in a fixed posture, refer to Figure 5-6 and Figure 12-13 As shown in FIG. 1 , when the chute 13a is opened, the lower end of the chute 13a does not reach the bottom, that is, there is a closed end. At this time, the lower end of the chute naturally forms a stop step to limit the upper guide block a from moving downward. On the other hand, the upper end of the chute 13a needs to be inserted from top to bottom for the positioning anchor column g, and also needs to limit the upper guide block a from moving upward. Therefore, as shown in FIG. Figure 12-13 The locking mechanism is shown. The locking mechanism includes a "C"-shaped lock hook 13b, the bottom end of which is hinged on the clamp rod 12, and the top end of the lock hook 13b is bent and penetrates the clamp rod 12 and then extends into the groove cavity of the slide groove 13a. In a natural state, the lock hook 13b is controlled by the locking tension spring and is always elastically pressed into the groove cavity of the slide groove 13a, and has a natural one-way locking function of "the positioning anchor column can go down but not up". When the lock hook 13b needs to be actively opened to facilitate the wire clamp to escape from the positioning installation part 10, the locking electric push rod 13d can be started, and the piston rod end of the locking electric push rod 13d moves downward and pulls down the anchor point 13c at the lock hook 13b, so that the lock hook 13b can be actively started, so that the upper groove end of the slide groove 13a forms an open state that is convenient for the wire clamp to escape.

[0051] 2. Secondary line locking clip 40

[0052] Secondary line locking clip 40 Figure 4-5 and Figure 12-13As shown, its main structure is formed by a combination of a secondary line groove 43, a secondary locking rod 41 and a transverse rod 42. The secondary locking rod 41 is divided into two groups, and a group of transverse rods 42 are matched to form a three-dimensional frame structure, so as to better hook the secondary line B laterally. The design purpose of the secondary line groove 43 is to improve the threading efficiency, and at the same time, it can cooperate with the secondary locking rod 41 to better bite the secondary line, which is convenient for the rapid installation of the secondary line B. Since the secondary line B is usually installed on the ground, it is necessary to pay attention to how the secondary line B can be unimpededly separated from the present invention after it is lifted into the air and the groove is completed with the main line clamp; in view of this, the secondary locking rod 41 of the present invention adopts a "T"-shaped plate structure. When in use, one end of the horizontal section of the secondary locking rod 41 is hinged to the clamp rod 12 through the support ear 41a, and the other end constitutes a locking end 41b with a gradually upward end, which is used to cooperate with the secondary line groove 43 to realize the bite-type fixing operation of the secondary line B. The vertical section of the secondary lock rod 41 extends toward the clamp rod 12 and forms a switch end 41c. At the same time, after the piston rod end of the locking electric push rod 13d passes horizontally through the adjustment hole on the clamp rod 12, it forms abutment or hinged fit with the switch end 41c of the secondary lock rod 41. In this way, whenever the locking electric push rod 13d performs a process action, it will drive the switch end 41c upward, and at this time the secondary lock rod 41 will produce a swinging action, and the warping structure of the locking end 41b can be used to cooperate with the secondary line slot to locate the secondary line position; refer to Figure 5 shown.

[0053] 3. Main line guide clip 30

[0054] The main line guide clamp 30 is designed to effectively guide the main line A downward when the present invention is pushed upward from the bottom, and the "V"-shaped design of the main line guide clamp 30 with the opening facing upward can effectively guide the main line A downward until the main line A falls into the matching groove 31a of the main guide fork 31 at the main line guide clamp 30. When the wire clamp is fixed, the head end notch e of the lower guide block b at the wire clamp is just at the same height as the matching groove 31a or there is a slight height difference, so the main line can also reliably fall into the head end notch e at this time.

[0055] When specifically designed, the main line guide clamp 30 is as follows Figure 3-7 and Figure 10-13 The main guide fork 31 and the auxiliary guide fork 32 are shown, and the purpose is to facilitate the main line to slide into the main line guide clamp 30 along the guide surface through the guidance of each fork, and finally fall into the head end notch e at the lower guide block b; the above structure solves the problems of inaccurate installation position and slow installation of the wire clamp in the traditional sense, and simplifies the action process, which is more suitable for use by robots. The auxiliary guide fork 32 adopts a movable guide fork, which plays a guiding role, and does not interfere with the sliding out of the main line, which is obviously more convenient in operation.

[0056] 4. Strike Department 20

[0057] The striking part 20 is also the present invention. In fact, the striking part 20 is an indispensable part of the wire clamp holder; however, the traditional striking part is to tighten the nut of the tension bolt c or the tension nut d by the self-spinning of the screw sleeve 21, thereby completing the tightening function. The striking part 20 of the present invention has the functions of "tightening + self-compensation", especially under the premise that the upper guide block a is fixed, it can perfectly match the upward movement of the lower guide block b under the large stroke, and finally realize the simultaneous clamping function of the main line and the auxiliary line through the two guide blocks.

[0058] The specific structure of the striking part 20 of the present invention is shown in FIG. Figure 4 and Figure 7-11 As shown, its main parts include a screw sleeve 21, a striking motor 22 for driving the screw sleeve 21 to rotate, and a compensation component 23 for providing a compensation function for the screw sleeve 21. Among them:

[0059] The driving end of the striking motor 22 is coaxially fixed with a transmission shaft 23a to achieve power transmission, and the transmission shaft 23a is sleeved with an outer guide sleeve 23b in a rotation-proof manner, and a screw sleeve 21 is fixed to the top of the outer guide sleeve 23b. When the striking motor 22 is working, the transmission shaft 23a rotates accordingly, and drives the outer guide sleeve 23b to rotate through the key connection with the outer guide sleeve 23b, and finally drives the screw sleeve 21 to produce a rotational motion.

[0060] At the same time, an annular protrusion 23d is also arranged at the outer guide sleeve 23b. Figure 8-9 As shown, the electromagnetic lock forms a stopper. The electromagnetic lock includes an electromagnet constituting a power member 23f, a lock tongue 23e located at the working end of the electromagnet, and a return spring 23g connecting the lock tongue 23e and the electromagnet. When working, under the action of the return spring, the lock tongue 23e always extends to the outer guide sleeve 23b. When the screw sleeve 21 is in the initial state, that is, the low position state, as shown in FIG. Figure 8 As shown, at this moment, the locking tongue 23e is just located above the annular protrusion 23d, thereby pressing the annular protrusion 23d, so that the outer guide sleeve 23b and even the screw sleeve 21 no longer ascend. When the screw sleeve 21 needs to be used, the electromagnet is energized at this moment, and the locking tongue 23e is sucked, and the locking tongue 23e overcomes the force of the return compression spring 23g and retracts, thereby unlocking the annular protrusion 23d; Subsequently, the outer guide sleeve 23b produces an upward action under the action of the jacking compression spring constituting the elastic member 23c, thereby driving the screw sleeve 21 to ascend, and realizing the action purpose of the self-compensation type. When the screw sleeve 21 ascends, the outer guide sleeve 23b ascends relative to the transmission shaft 23a, and at the same time, the transmission shaft 23a applies a rotational force to the screw sleeve 21 through the outer guide sleeve 23b, i.e., the composite self-compensation action function of the "rotation+axial upward movement" of the screw sleeve 21 is guaranteed.

[0061] In order to further understand the present invention, Figure 1-13 , the actual working process of the present invention is described as follows:

[0062] 1) Get the traditional Figure 1 After the J-type wire clamp shown in the figure, the wire clamp is drilled and screws are installed to form the following Figure 2 The new wire clamp with positioning anchor post g is shown.

[0063] 2) Press the screw sleeve 21 of the present invention to make the screw sleeve 21 move downward and reset; at the same time, the locking electric push rod 13d moves downward, and the lock hook 13b is forced to open. When the locking electric push rod 13d returns and pulls the anchor point 13c at the lock hook 13b, so that the lock hook 13b is completely in the open state, the wire clamp is installed. Afterwards, install the new wire clamp of step 1). At this time, due to the presence of the positioning anchor column g, the positioning anchor column g will move downward along the direction of the slide groove 13a, thereby having the advantages of rapid installation and accurate installation of the wire clamp. The wire clamp can quickly and accurately reach the working position along the slide groove 13a. When the positioning anchor column is as Figure 6 After being clamped into the working position as shown; among the two positioning anchor posts g, the lower positioning anchor post is blocked by the lower groove end of the slide groove 13a, and the upper positioning anchor post will be blocked by the hook head of the lock hook 13b with a locking tension spring in the subsequent step 4), thereby realizing the reliable fixation of the upper guide block a of the wire clamp; at this time, the first end notch e of the lower guide block b faces upward, instead of the downward installation method of the traditional pull-down clamp. And in the process of the wire clamp going down along the slide groove 13a, the lock hook 13b is in an open state, that is, at this time, the piston rod end of the locking electric push rod 13d continues to apply a downward pulling force to the anchor point 13c at the lock hook 13b.

[0064] 3) Since the locking electric push rod 13d is always in the return state, the secondary lock rod 41 is also always in the open state, that is, the locking end 41b is always located in the receiving groove 12a. After the wire clamp is installed, the secondary wire is inserted through the secondary wire groove 43. After that, the locking electric push rod 13d performs a forward action, thereby pushing the switch end 41c of the secondary lock rod 41 through the guiding action of the adjustment hole and the slide rod 13e, and the secondary lock rod 41 produces a swing action until the secondary lock rod 41 cooperates with the secondary wire groove to bite the secondary wire. At this time, the secondary wire is Figure 2 It is shown as being located between the upper guide block a and the lower guide block b, but has not yet been reliably installed; the cooperation of the secondary locking rod 41 and the secondary line groove 43 can effectively fix the secondary line, preventing the failure of the line clamp and groove caused by the secondary line falling off and moving.

[0065] 4) When the locking electric push rod 13d performs the process action, the piston rod end of the locking electric push rod 13d will gradually relax the pressure on the anchor point 13c at the lock hook 13b, and the lock hook 13b will be reset under the action of the locking tension spring, thereby clamping the wire clamp and completing the upward and downward limit action of the upper guide block a at the wire clamp.

[0066] 5) When the secondary line is fixed and the lock hook 13b is reset, the electromagnet constituting the power member 23f is energized to absorb the lock tongue 23e and release the outer guide sleeve 23b with the annular protrusion 23d. Fig. 9 shown.

[0067] 6) When the striking begins, the screw sleeve 21 rotates and turns the tightening nut d. In the process of tightening the tightening nut d of the wire clamp, the lower guide block b and the tightening nut d continuously move upward; due to the elastic force of the lifting spring under the outer guide sleeve 23b, the outer guide sleeve 23b also performs a compensatory upward movement until the striking is completed.

[0068] 7) After the wire clamp is assembled, the locking electric push rod 13d generates a return action, driving the secondary line locking clamp 40 to reset and release the secondary line. At the same time, the locking electric push rod 13d also drives the lock hook 13b to move, and the lock hook 13b is actively opened. Then, the present invention is pulled down, and the present invention is completely separated from the wire clamp, and the wire clamp is left on the main line located at a high altitude, and finally the entire wire clamp and groove process is completed.

[0069] Since the present invention is an inverted top-mounted installation structure of the wire clamp, the main line is assembled from the bottom up. In actual operation, the present invention is lifted by a mechanical arm to complete the operation, so the main line is fixed and the entire device moves with the secondary line. Before the main line is connected, the secondary guide fork 32 will be reset under the action of gravity. At this time, the present invention is lifted by the mechanical arm to connect the main line from bottom to top. After the grooving is completed, the present invention is withdrawn from top to bottom. At this time, the secondary guide fork 32 will rotate automatically to avoid interference with the main line to be separated.

A self-compensating J-type wire clamp installer, comprising a positioning and mounting portion (10) for placing the wire clamp, a striking portion (20) for tightening an object to be rotated is arranged at the positioning and mounting portion (10), the striking portion (20) comprising a screw sleeve (21) arranged coaxially with the object to be rotated, the screw sleeve (21) is driven by a striking motor (22) to generate a coaxial rotation motion relative to the object to be rotated; characterized in that: The installer further comprises a compensation component (23) for driving the screw sleeve (21) to produce an axially similar motion relative to the rotating object while the screw sleeve (21) produces a rotational motion; the compensation component (23) comprises a transmission shaft (23a) coaxially fixed to the output shaft of the striking motor (22); an outer guide sleeve (23b) is coaxially sleeved outside the transmission shaft (23a), and a rotation-stopping fit is formed between the outer guide sleeve (23b) and the transmission shaft (23a); the top end of the outer guide sleeve (23b) is coaxially assembled with the screw sleeve (21); the compensation component (23) further comprises an elastic member (23c) for driving the outer guide sleeve (23b) to produce an axial upward motion relative to the transmission shaft (23a); The transmission shaft (23a) is a square shaft, and the sleeve cavity shape of the outer guide sleeve (23b) is adapted to the outer wall shape of the transmission shaft (23a), so that the two form a spline-type anti-rotation matching relationship.

2. A self-compensating J-type wire clamp installer according to claim 1, characterized in that: An annular protrusion (23d) is coaxially arranged at the top end of the outer guide sleeve (23b), and a locking tongue (23e) for limiting the outer guide sleeve (23b) from generating an axial upward movement is arranged on one side of the outer guide sleeve (23b). The locking tongue (23e) is controlled by a power member (23f) to generate a radial reciprocating linear movement relative to the outer guide sleeve (23b); when the outer guide sleeve (23b) is in a low initial position, the locking tongue (23e) extends and is located above the annular protrusion (23d), thereby forming a one-way stop fit with the annular protrusion (23d); when the outer guide sleeve (23b) is in a high working position, the locking tongue (23e) retracts under the control of the power member (23f), and the outer guide sleeve (23b) generates an axial lifting movement under the action of the elastic member (23c).

3. A self-compensating J-type wire clamp installer according to claim 2, characterized in that: The power piece (23f) is an electromagnet, and the lock tongue (23e) and the power piece (23f) are connected to each other via a return compression spring (23g), so that when the power piece (23f) is started, the return compression spring (23g) is compressed to drive the lock tongue (23e) to produce a retracting action; and the upper corner end of the top of the lock tongue (23e) is chamfered so that when the annular protrusion (23d) produces a downward movement, the return compression spring (23g) is pressed to produce a force-compressed action.

4. A self-compensating J-type wire clamp installer according to claim 2, characterized in that: The sleeve cavity of the screw sleeve (21) matches the top diameter of the outer guide sleeve (23b), and the stopper of the bottom end surface of the screw sleeve (21) fits on the upper shoulder of the outer guide sleeve (23b) from top to bottom, and the screw sleeve (21) and the outer guide sleeve (23b) are fixedly connected by a set screw.
