Description

Technical Field

[0001] This utility model relates to the technical field of vehicle rearview mirror installation equipment, specifically to a vehicle rearview mirror assembly fixture. Background Technology

[0002] As attached Figure 1 As shown, spring structures are used in the rearview mirrors of trucks, commercial vehicles, and other vehicles. After installation, the spring structure is in a pre-compressed state to provide constant elastic support for the rearview mirror components, ensuring the stability of the mirror during use. Currently, the spring structure is fitted onto the mirror arm base, which is fitted onto the outside of the wiring harness mirror arm, with the top of the wiring harness mirror arm protruding beyond the top of the mirror arm base. A limiting chuck is then installed on the top of the wiring harness mirror arm, using the limiting chuck to pre-assemble the spring by compression.

[0003] After installing the limiting chuck, due to the spring's counter-elastic force on the limiting chuck, to prevent the limiting chuck from detaching from the top of the wire harness arm, as shown in the attached... Figure 2 As shown, the inventor designed a vertical through groove and a blind hole groove on the limiting chuck, and set a guide protrusion on the outer wall of the wire harness lens arm that cooperates with the vertical through groove. A horizontal groove with a width greater than the thickness of the wire harness lens arm is set on the guide protrusion. The width of the guide protrusion is less than or equal to the width of the blind hole groove. When installing the limiting chuck, first align the vertical through groove with the guide protrusion, and then push the limiting chuck downward (the limiting chuck will compress the spring when it moves downward). When the limiting chuck is pressed down until it is aligned with the horizontal groove, rotate the limiting chuck so that the blind hole groove is aligned with the guide protrusion. Then release the downward pressure on the limiting chuck. Under the elastic force of the spring, the limiting chuck moves upward and makes the guide protrusion engage with the blind hole groove. The blind hole groove can prevent the limiting chuck from rotating and stably provide a clamping and fixing effect on the spring.

[0004] Although the limiting chuck and wire harness arm structure designed by the inventor can stably install the limiting chuck and ensure its clamping and fixing effect on the spring, the installation of the limiting chuck is currently generally done manually. In actual installation, when the limiting chuck is manually pressed down, it will be subject to the spring's reaction force. After the limiting chuck is pressed down to align with the transverse groove, it is necessary to maintain the pressed-down state of the limiting chuck, and then manually rotate the limiting chuck until the blind hole groove is aligned with the guide protrusion. Finally, the limiting chuck is released, and the limiting chuck, under the elastic force of the spring, causes the blind hole groove to automatically engage with the guide protrusion, thus completing the installation of the limiting chuck. During installation, the chuck needs to be pressed down to keep it from shifting vertically, and then rotated horizontally. This requires applying force to the chuck from two directions, which is not only very laborious, but also makes it difficult to control the chuck to rotate precisely so that the blind hole groove and the guide protrusion are aligned. This seriously affects the installation efficiency of the chuck. To address this, the inventor designed this assembly fixture to reduce the labor intensity of manual installation and improve installation efficiency. Utility Model Content

[0005] The present invention aims to provide a tooling for assembling automotive rearview mirrors, in order to solve the problem that manual installation of the limiting chuck in rearview mirrors is very laborious and inefficient in the prior art.

[0006] To solve the above problems, the present invention adopts the following technical solution: a vehicle rearview mirror assembly fixture, including a base and a positioning component fixedly connected to the base. The positioning component is used to position the wiring harness mirror arm. A vertical pressing member slides vertically above the positioning component. A rotating mechanism is rotatably connected to the bottom of the vertical pressing member with the central axis of the wiring harness mirror arm as the rotation center. The rotating mechanism is provided with a pressing part that abuts against a limiting chuck and a plugging part that can be vertically inserted into the limiting chuck. When the rotating mechanism presses the limiting chuck down to be directly opposite the transverse groove of the wiring harness mirror arm, the plugging part and the limiting chuck are inserted into each other.

[0007] The principle of this solution is as follows: When installing the limiting chuck designed by the inventor, the wire harness lens arm is first installed onto the positioning component. The positioning component is used to position the wire harness lens arm, preventing the wire harness lens arm from rotating freely when the limiting chuck is pressed onto it, which would affect the installation efficiency. After the wire harness lens arm is installed and positioned, the spring in the prior art can be sleeved on the wire harness lens arm, and then the limiting chuck is placed on the top of the wire harness lens arm. At this time, the top of the spring is in contact with the wire harness lens arm. Then, the vertical extrusion member slides vertically, driving the bottom connecting clamping part and the insertion part to slide vertically simultaneously. After the clamping part contacts the limiting chuck, it presses the limiting chuck downward, and the spring is compressed and stores force. When the rotating mechanism presses the limiting chuck down to be aligned with the transverse groove of the wire harness lens arm, the insertion part in the rotating mechanism and the limiting chuck are inserted into each other. At this time, only external force is needed to drive the rotating mechanism to rotate relative to the vertical extrusion member, and the insertion part can drive the limiting chuck to rotate. When the limiting chuck rotates to the point where the blind hole groove on the limiting chuck is aligned with the guide protrusion on the wire harness lens arm, the vertical extrusion member slides upward, and the downward extrusion force of the vertical extrusion member on the driving mechanism decreases. Under the action of the spring's reverse elastic force, the limiting chuck moves upward relative to the wire harness lens arm, so that the guide protrusion on the wire harness lens arm is engaged in the blind hole groove on the limiting chuck, realizing the precise installation of the limiting chuck.

[0008] The beneficial effects of this solution are as follows: Compared to existing technologies where manual installation of the limiting chuck is difficult because it is hard to keep the limiting chuck aligned with the transverse groove, and then rotates the limiting chuck for precise installation, making manual installation not only laborious but also inaccurate and inefficient, this application uses a vertical pressing component to press the rotating mechanism downwards. This allows the limiting chuck to be smoothly pressed downwards until it is aligned with the transverse groove. The rotating mechanism is rotatably connected to the vertical pressing component. When the limiting chuck is pressed down to be aligned with the transverse groove, it can be easily rotated without vertical displacement, allowing it to be easily rotated until the blind hole groove and guide protrusion are aligned. Then, the vertical pressing component moves upwards, and the limiting chuck automatically completes the installation process under the action of spring force. The entire process makes the installation of the limiting chuck very convenient and precise, effectively reducing the labor intensity of manual installation, and the automatic completion of installation significantly improves the installation efficiency of the limiting chuck.

[0009] Preferably, as an improvement, the rotating mechanism includes an outer sleeve and an inner sleeve coaxially rotatably connected inside the outer sleeve. The inner sleeve is fixedly connected to the vertical pressing member. The pressing part includes a pressing surface disposed at the bottom of the outer sleeve. The insertion part includes a pin fixedly connected to the bottom of the outer sleeve. The arm of the wire harness is provided with a slot that engages with the pin.

[0010] In this design, the inner sleeve is fixedly connected to the vertical extrusion member, and the outer sleeve is rotatably connected to the inner sleeve. When the vertical extrusion member slides vertically, it can drive the inner sleeve and the outer sleeve to move vertically. When the bottom of the outer sleeve contacts the limiting chuck and pushes the limiting chuck downward to be directly opposite the transverse groove, it can drive the outer sleeve to rotate relative to the inner sleeve, thereby causing the pin on the outer sleeve to drive the limiting chuck to rotate. The whole structure is simple and very convenient to operate.

[0011] Preferably, as an improvement, the number of pins is multiple, and the multiple pins are evenly arranged along the circumference of the inner sleeve.

[0012] In this solution, multiple pins are set, and these pins are evenly arranged along the axial direction of the inner sleeve. When the outer sleeve drives the limit chuck to rotate, the force on the limit chuck is more even, which makes the limit chuck rotate more smoothly and effectively improves the accuracy and efficiency of the limit chuck installation.

[0013] Preferably, as an improvement, a rotation angle control component is provided between the outer sleeve and the inner sleeve to control the rotation angle range of the outer sleeve relative to the inner sleeve. Under the control of the rotation angle control component, the rotation angle value of the limiting chuck from the state where the vertical through groove and the guide protrusion are vertically aligned to the state where the blind hole groove and the guide protrusion are aligned is β. The rotation angle value of the outer sleeve relative to the inner sleeve is equal to β.

[0014] In this solution, a rotation angle control component is used to control the rotation angle of the outer sleeve relative to the inner sleeve. When the limiting chuck is just installed at the top of the wire harness arm, the vertical through groove on the limiting chuck engages with the guide protrusion on the outer wall of the top of the wire harness arm. As the limiting chuck is pressed downwards until it is aligned with the horizontal groove, the limiting chuck is rotated. At this time, the limiting chuck rotates from a state where the vertical through groove and the guide protrusion are vertically aligned to a state where the blind hole groove and the guide protrusion are aligned. The rotation angle value is β. During the rotation of the limiting chuck, the rotation angle control component controls the rotation angle of the outer sleeve relative to the inner sleeve, and the controlled rotation angle value is equal to β. That is, the rotation angle control component in this solution can precisely brake the "end point" of the rotation of the limiting chuck, making the rotation installation of the limiting chuck more accurate and efficient.

[0015] Preferably, as an improvement, the rotation angle control component includes a rotationally engaging angle control protrusion and an angle control arc groove, wherein the arc size of the angle control arc groove is α, and α = β × (π / 180).

[0016] In this design, the angle of rotation of the inner sleeve relative to the outer sleeve is controlled by setting an angle control protrusion and an angle control arc groove that are in tandem with relative rotation. The structure is stable and the rotation angle is controlled very precisely.

[0017] Preferably, as an improvement, a rotating bearing is connected between the vertical extruder and the outer sleeve.

[0018] After the outer sleeve presses downwards against the limiting chuck, the limiting chuck is subjected to a counterforce from the spring. This counterforce acts upwards on the contact point between the outer sleeve and the vertical pressing component. When the outer sleeve is subsequently rotated, causing the limiting chuck to rotate, friction exists between the top of the outer sleeve and the vertical pressing component. Over time, this will cause wear on both the outer sleeve and the vertical pressing component. In this solution, a rotating bearing is installed between the outer sleeve and the vertical pressing component. This not only effectively reduces wear between the two components but also reduces friction, thus reducing the rotational force required to rotate the limiting chuck and making the installation of the limiting chuck easier.

[0019] Preferably, as an improvement, the bottom of the vertical extruder is fixedly connected with a retaining ring that protrudes beyond the side wall of the vertical extruder, and the shaft bearing is mounted on the retaining ring.

[0020] In this design, a retaining ring is fixedly connected to the bottom of the vertical extrusion component to facilitate the installation and fixation of the shaft bearing.

[0021] Preferably, as an improvement, a manual rotating rod is connected to the outer sleeve, and the manual rotating rod is arranged radially along the inner sleeve.

[0022] In this design, a manual rotating rod is connected to the outer sleeve. When the vertical extruder presses the limiting chuck downwards until it is aligned with the transverse groove, the manual rotating rod can be manually rotated. The manual rotating rod drives the outer sleeve to rotate, causing the limiting chuck to rotate until the blind hole groove is aligned with the guide protrusion. Compared to using other control structures to control the rotation of the outer sleeve, the manual rotating rod method in this design is simpler and more convenient to operate.

[0023] Preferably, as an improvement, the positioning component includes a positioning seat and a positioning pin fixedly connected to the positioning seat. The base is provided with a mounting groove, the positioning seat is fixedly connected to the mounting groove, and the positioning seat is provided with a limiting pin that is inserted into the wire harness lens arm. The positioning pin is coaxially arranged with the wire harness lens arm and the positioning pin is inserted into the wire harness lens arm.

[0024] In this design, the limiting pin on the positioning seat engages with the wire harness mirror arm. When the wire harness mirror arm needs to be installed, the positioning pin guides it. After the wire harness mirror arm is installed and inserted into the positioning slot, the limiting pin prevents the wire harness mirror arm from rotating when the limiting chuck is rotated, thus avoiding the blind hole groove on the limiting chuck aligning with the guide protrusion on the wire harness mirror arm. This improves the stability and accuracy of the limiting chuck installation process and increases the efficiency of rearview mirror installation.

[0025] Preferably, as an improvement, the top of the positioning pin protrudes above the top surface of the wire harness lens arm, and the bottom of the inner sleeve is provided with a guide hole that cooperates with the positioning pin.

[0026] In this design, a guide hole is provided at the bottom of the inner sleeve to mate with the top of the positioning pin. When the vertical pressing component pushes the entire rotating mechanism downward, the positioning pin contacts the guide hole first. The positioning pin can guide the downward movement of the entire rotating mechanism, making the vertical pressing of the rotating mechanism more stable and precise.

[0027] Preferably, as an improvement, both ends of the tooth mold reinforcing plate are fixedly connected to the two side tooth mold connecting plates, and both ends of the universal reinforcing plate are fixedly connected to the two side universal connecting plates.

[0028] In this design, the two ends of the tooth mold reinforcing plate are fixedly connected to the two side tooth mold connecting plates. The tooth mold reinforcing plate not only provides auxiliary reinforcement to the structural strength of the tooth mold movable module, but also provides auxiliary support to the two side tooth mold connecting plates, further improving the stability of the entire tooth mold movable module after installation and fixation (fixing the two ends of the universal reinforcing plate to the two side universal connecting plates in the universal movable module can also improve the stability of the universal movable module), thus improving the quality of T-beam forming.

[0037] The following detailed description illustrates the specific implementation method:

[0038] The reference numerals in the accompanying drawings include: lens base 1, wire harness lens arm 2, guide protrusion 201, horizontal groove 202, positioning hole 203, spring 3, limit chuck 4, vertical through groove 401, blind hole groove 402, slot 403, base 5, positioning seat 6, positioning pin 7, limit pin 8, vertical extrusion part 9, guide hole 901, retaining ring 902, outer sleeve 10, angle control arc groove 1001, inner sleeve 11, anti-detachment protrusion 1101, angle control protrusion 1102, external threaded post 12, pin 13, manual rotating rod 14, rotating bearing 15.

[0039] The rearview mirror structure designed by the inventor is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the rearview mirror includes a mirror base 1, a wire harness mirror arm 2, a spring 3, and a limiting chuck 4. Multiple vertically arranged guide protrusions 201 are integrally formed on the outer wall of the wire harness mirror arm 2, and a transverse groove 202 circumferentially penetrating the guide protrusions 201 is provided on the outer wall of the wire harness mirror arm 2. The width of the transverse groove 202 is greater than the thickness of the limiting chuck 4. After assembly, the limiting chuck 4 is coaxially arranged with the wire harness mirror arm 2, and the limiting chuck 4 has an integrally formed vertical through groove 401 and a blind hole groove 402 that slide vertically with the guide protrusions 201. During the installation of the rearview mirror, the base 5, the wire harness mirror arm 2, and the spring 3 are first installed in place, and finally the limiting chuck 4 is installed.

[0040] In the actual installation process, when installing the limiting chuck 4, first place the limiting chuck 4 above the wire harness lens arm 2, so that the vertical through groove 401 on the limiting chuck 4 is aligned with the guide protrusion 201. Then push the limiting chuck 4 downward, the guide protrusion 201 and the vertical through groove 401 slide relative to each other, and the bottom of the limiting chuck 4 compresses the spring 3. When the limiting chuck 4 moves downward until it is aligned with the horizontal groove 202, stop moving the limiting chuck 4 downward. Then rotate the limiting chuck 4 in the horizontal plane so that the blind hole groove 402 on the limiting chuck 4 is aligned with the guide protrusion 201 in the vertical direction. Finally, release the downward pressure on the limiting chuck 4. Under the action of the spring 3, the limiting chuck 4 automatically moves upward and the blind hole groove 402 automatically engages with the guide protrusion 201, so that the limiting chuck 4 is installed and fixed, and finally the installation and fixing of the limiting chuck 4 is achieved.

[0041] Example 1

[0042] This embodiment is as shown in the attached figure. Figure 4 and Figure 5The image shows a vehicle rearview mirror assembly fixture, including a base 5. The top of the base 5 has a contoured groove adapted to the mirror mount 1 of a prior art rearview mirror, for placing the mirror mount 1 during use. A positioning component for positioning a wiring harness mirror arm 2 is fixedly connected to the base 5. The base 5 has a mounting groove whose top communicates with the contoured groove, and the positioning component is installed in the mounting groove. Specifically, the positioning component includes a positioning seat 6 and a positioning pin 7 fixedly connected to the positioning seat 6. The positioning seat 6 is fixedly connected to the mounting groove by screws. The bottom of the positioning seat 6 has a receiving groove, and the head of the positioning pin 7 is confined within the receiving groove. The shaft of the positioning pin 7 is vertically oriented and coaxially aligned with the wiring harness mirror arm 2. The wiring harness mirror arm 2 has a vertically penetrating through hole inside, and the positioning pin 7 is inserted into the through hole, allowing the positioning pin 7 to position the wiring harness mirror arm 2 vertically. The upper guide is positioned; in addition, the top surface of the positioning seat 6 is integrally formed with multiple limiting pins 8 arranged along the circumference of the top of the positioning seat 6, and the bottom of the wire harness lens arm 2 is provided with a positioning hole 203. The limiting pins 8 are inserted into the positioning hole 203 at the bottom of the wire harness lens arm 2. When the bottom surface of the wire harness lens arm 2 contacts the top surface of the positioning seat 6, the positioning pin 7 is inserted into the through hole of the wire harness lens arm 2, and the limiting pin 8 is inserted into the positioning hole 203, so that the wire harness lens arm 2 is installed and positioned and cannot be rotated in the horizontal direction.

[0043] Combination Figure 4 and Figure 5 A vertically sliding extrusion member 9 is vertically connected above the positioning pin 7. The vertically sliding extrusion member 9 is driven by a mechanical power structure such as a cylinder, hydraulic cylinder, or lead screw, which is not described in detail here. A rotating mechanism is rotatably connected to the bottom of the vertically sliding extrusion member 9 with the central axis of the wire harness lens arm 2 as the rotation center. The rotating mechanism has a clamping part that abuts against the limiting chuck 4 and a plugging part that can be vertically inserted into the limiting chuck 4. When the rotating mechanism presses the limiting chuck 4 down to be directly opposite the transverse groove 202 of the wire harness lens arm 2, the plugging part and the limiting chuck 4 are inserted into each other.

[0044] In this embodiment, the rotating mechanism includes an outer sleeve 10 and an inner sleeve 11 coaxially rotatably connected within the outer sleeve 10. The bottom of the vertical extrusion member 9 is integrally formed with an externally threaded post 12, and the top of the inner sleeve 11 is provided with an internally threaded hole that is threadedly fixed to the externally threaded post 12, allowing the inner sleeve 11 to be fixed to the vertical extrusion member 9. Simultaneously, in this embodiment, the top of the positioning pin 7 extends to the top surface of the wire harness lens arm 2, and the bottom of the inner sleeve 11 has a guide hole 901 for insertion and engagement with the positioning pin 7. The top surface of the positioning pin 7 is chamfered to allow the top of the positioning pin 7 to be quickly and accurately inserted into the guide hole 901.

[0045] Combination Figure 5 and Figure 6The abutting part is an abutting surface located between the bottom of the outer sleeve 10 and the top surface of the limiting chuck 4. The insertion part includes a pin 13 fixedly connected to the bottom surface of the outer sleeve 10 by interference fit or integral molding. The limiting chuck 4 is provided with a slot 403 that vertically engages with the pin 13. The slot 403 is vertically inserted through the limiting chuck 4. In order to drive the limiting chuck 4 to rotate in the horizontal plane more smoothly, there are multiple pins 13 in this embodiment, and the multiple pins 13 are evenly arranged along the circumference of the inner sleeve 11. In addition, in order to make the outer sleeve 10 more labor-saving and convenient to be manually rotated, a manual rotating rod 14 is fixedly connected to the outer wall of the outer sleeve 10 by threaded connection or welding. The manual rotating rod 14 is arranged along the radial direction of the inner sleeve 11.

[0046] Meanwhile, in order to ensure a more stable fit between the top of the outer sleeve 10 and the bottom of the vertical extrusion member 9, a retaining ring 902 protruding from the outer wall of the vertical extrusion member 9 is integrally formed on the bottom outer wall of the vertical extrusion member 9 in this embodiment, and the top of the outer sleeve 10 and the bottom surface of the retaining ring 902 are in surface contact. In addition, in order to prevent the outer sleeve 10 from detaching from the inner sleeve 11 in the vertical direction during use, a mating hole with an inner diameter larger than the guide hole 901 is opened at the bottom of the inner sleeve 11 in this embodiment, and an anti-detachment protrusion 1101 is integrally formed on the bottom outer wall of the inner sleeve 11, and the top surface of the anti-detachment protrusion 1101 is in contact with the top wall of the mating hole.

[0047] The specific implementation process is as follows:

[0048] When the limiting chuck 4 needs to be installed, first place the mirror mount 1 in the rearview mirror into the square groove, and make the through hole of the wire harness mirror arm 2 engage with the positioning pin 7. The positioning hole 203 at the bottom of the wire harness mirror arm 2 engages with the limiting pin 8. At this time, the wire harness mirror arm 2 is positioned. Then, the spring 3 of the prior art is sleeved on the outside of the wire harness mirror arm 2, and the limiting chuck 4 is sleeved from top to bottom onto the top of the wire harness mirror arm 2. The guide protrusion 201 on the wire harness mirror arm 2 guides the limiting chuck 4, ensuring that the vertical through groove 401 on the limiting chuck 4 slides with the guide protrusion 201. When the bottom of the limiting chuck 4 contacts the top of the spring 3, the limiting chuck 4 cannot move further downward, thus completing the initial installation of the limiting chuck 4.

[0049] After the limiting chuck 4 is initially installed, the vertical pressing member 9 moves downwards, and the drive mechanism moves downwards synchronously with the vertical pressing member 9. First, the top of the positioning pin 7 is inserted into the guide hole 901 of the inner sleeve 11. The positioning pin 7 guides the drive mechanism to ensure the stability and accuracy of the drive mechanism when it moves downwards. As the drive mechanism continues to move downwards, the pressing surface of the outer sleeve 10 contacts and abuts against the top surface of the limiting chuck 4. Under the pressing action of the outer sleeve 10, the limiting chuck 4 moves downwards and presses the spring 3. When the limiting chuck 4 moves downwards to the point where the limiting chuck 4 is aligned with the transverse groove 202 on the wire harness lens arm 2, the pin 13 is inserted into the slot 403. Then the vertical extrusion member 9 stops moving downwards. At this time, the manual rotating rod 14 drives the outer sleeve 10 to rotate. Since the pin 13 is inserted into the slot 403, the rotation of the outer sleeve 10 will drive the limiting chuck 4 to rotate in the horizontal plane. When the limiting chuck 4 rotates to the point where the blind hole groove 402 on the limiting chuck 4 is aligned with the guide protrusion 201 on the wire harness lens arm 2, the rotation of the limiting chuck 4 stops. Then the vertical extrusion member 9 moves upwards, and the limiting chuck 4 moves upwards under the elastic force of the spring 3, so that the blind hole groove 402 on the limiting chuck 4 automatically engages with the guide protrusion 201, realizing the installation and fixation of the limiting chuck 4. The installation of the limiting chuck 4 in the whole process is very labor-saving, precise and efficient.

[0050] Example 2

[0051] The difference between Example 2 and Example 1 is as follows: Figure 7 As shown, in this example, a rotating bearing 15 connects the vertical extrusion member 9 and the outer sleeve 10. Specifically, the rotating bearing 15 is a deep groove bearing fixed to the baffle plate by an interference fit, and the top of the outer sleeve 10 abuts against the rotating bearing 15. In this embodiment, by setting the rotating bearing 15, when the outer sleeve 10 is manually driven to rotate by the manual lever 14, the top of the outer sleeve 10 rotates with the baffle plate through the rotating bearing 15, reducing the friction between the outer sleeve 10 and the baffle plate during rotation, making the rotation of the outer sleeve 10 more effortless and effectively reducing the intensity of manual labor.

[0052] Example 3

[0053] The difference between Embodiment 3 and Embodiment 1 is that in this embodiment, a rotation angle control component is provided between the outer sleeve 10 and the inner sleeve 11 to control the rotation angle range of the outer sleeve 10 relative to the inner sleeve 11. Under the control of the rotation angle control component, the limiting chuck 4 rotates from a state where the vertical through groove 401 and the guide protrusion 201 are vertically aligned to a state where the blind hole groove 402 and the guide protrusion 201 are directly aligned. The rotation angle value of the outer sleeve 10 relative to the inner sleeve 11 is equal to β. Specifically, as shown... Figure 8As shown, the rotation angle control assembly includes a rotationally engaging angle control protrusion 1102 and an angle control arc groove 1001. The angle control protrusion 1102 is integrally formed on the outer wall of the inner sleeve 11, and the angle control arc groove 1001 is integrally formed on the inner wall of the outer sleeve 10. The arc of the angle control arc groove 1001 is α, where α = β × (π / 180).

[0054] In this embodiment, by setting mutually rotating and cooperating angle control protrusions 1102 and angle control arc grooves 1001, when the outer sleeve 10 presses the limiting chuck 4 downwards until the limiting chuck 4 is aligned with the transverse groove 202 of the wire harness lens arm 2, and the outer sleeve 10 is manually driven to rotate relative to the inner sleeve 11 by the manual rotating rod 14, due to the presence of angle control protrusions 1102 and angle control arc grooves 1001, when the outer sleeve 10 drives the limiting chuck 4 to rotate so that the blind hole groove 402 is aligned with the guide protrusion 201, the angle control protrusion 1102 contacts the side wall of the angle control arc groove 1001, so that the outer sleeve 10 can no longer rotate relative to the inner sleeve 11, that is, the rotation of the outer sleeve 10 can be positioned, making the rotation of the limiting chuck 4 more precise and the installation of the limiting chuck 4 more efficient.
