Description

Technical Field

[0001] This invention relates to the field of exposure lamp manufacturing technology, and in particular to a clamping fixture for injecting mud into lamp tubes. Background Technology

[0002] Exposure lamps are ultraviolet light sources specifically designed for industrial equipment. They are suitable for applications such as PS plate exposure, printed circuit board (PCB) manufacturing, and UV curing. Typical applications include exposure processes in the optoelectronics, liquid crystal, and semiconductor industries.

[0003] When assembling an exposure lamp, the lamp tube is connected to the lamp holder. To enhance stability at the connection point, mud is injected into the gap. The mud slurry then dries and sets to ensure the stability of the lamp tube. Before injecting mud, the lamp tube and lamp holder need to be manually aligned and positioned. During the mud injection process, it is also necessary to ensure that the two remain relatively stable. Therefore, it is relatively troublesome for a single person to operate, the mud injection efficiency is relatively low, and it is prone to shaking, which can lead to inaccurate lamp tube assembly. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the lamp tube and lamp holder need to be manually aligned and mud is injected in the prior art, the present invention provides a clamping tool for injecting mud into the lamp tube that can position the lamp tube and clamp the lamp holder at the tail end of the lamp tube.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a clamping fixture for injecting mud into lamp tubes, including a base plate, a support rod installed on the top of the base plate, an adjustment mechanism installed on the top of the support rod, and a plurality of clamping mechanisms installed on one side of the adjustment mechanism; the adjustment mechanism includes two oppositely arranged end blocks, a vertical plate installed between the end blocks, a rotating roller rotatably installed between the end blocks, a plurality of grooves opened on the rotating roller, and a sliding rod fixedly installed between the end blocks. The number of grooves is equal to the number of clamping mechanisms. The grooves are spirally and symmetrically opened on the outer wall of the rotating roller. One end of the clamping mechanism facing the rotating roller is slidably connected to the corresponding groove, and one side of the clamping mechanism is slidably installed on the sliding rod.

[0006] Furthermore, to facilitate manual adjustment of the rotation of the roller, a gearbox is installed on the outer wall of each of the end blocks, and a knob is installed on the gearbox. The gearbox is connected to the shaft end of the roller for transmission.

[0007] Furthermore, in order to enable the clamping mechanism to effectively clamp the lamp tube and the lamp holder, the clamping mechanism includes a moving block, a sliding sleeve that passes through the moving block, a guide head installed on one side of the moving block, a pressing component installed on the top of one side of the moving block, an extension frame installed on the bottom of one side of the moving block, and a support frame installed below the extension frame.

[0008] Furthermore, to enable the pressing component to be height-adjusted relative to the support frame to accommodate lamp tubes of different lengths, a guide rail is provided on one side wall of the moving block. The pressing component includes a lifting block, and a guide groove is provided on one side of the lifting block. The guide rail is slidably disposed with the guide groove. A holding module is fixedly installed on the top of the lifting block, and a slot is provided at the bottom of the lifting block. A locking block is provided in the slot, and a connecting column is installed at the bottom of the locking block. A slider is installed at the bottom of the connecting column. A height adjustment component is installed on the end face of the end block facing the clamping mechanism. The slider is slidably connected to the height adjustment component. A limit frame is also installed on the lifting block.

[0009] Furthermore, in order to enable the holding module to press the lamp holder tightly against the tail end of the lamp tube for easy mud injection, the holding module includes a hinge seat mounted on the top of the lifting block, a holding arm hinged to the top of the hinge seat, an assembly rod mounted on the end of the holding arm, a holding head mounted on the bottom of the assembly rod, a swing arm hinged to the hinge seat, and a connecting arm hinged to the middle of the swing arm. The end of the connecting arm away from the swing arm is hinged to the middle of the holding arm. An extension arm is fixedly mounted on the end of the swing arm, and a through hole is opened on the extension arm. A cover plate is mounted on the top of the end block, and a push-pull assembly is mounted on the cover plate. The end of the push-pull assembly away from the cover plate passes through the through hole.

[0010] Furthermore, in order to enable the extension frame to effectively support the outer wall of the lamp tube end of different specifications, an annular sleeve is installed at the end of the extension frame away from the moving block, and a lifting rod is installed at the bottom of the annular sleeve; the support frame includes an annular plate located directly below the annular sleeve, an assembly frame installed on the outside of the annular plate, an adjusting ring coaxially arranged with the annular plate, and a clamping plate located between the adjusting ring and the annular plate, with the top of the clamping plate slidably connected to the annular plate.

[0011] Furthermore, to ensure that the rotation of the adjusting ring accurately moves the clamping plate, the assembly frame is C-shaped, with an arc-shaped block at the bottom of the inner wall of the assembly frame, and an arc-shaped groove on the outer bottom of the adjusting ring, the arc-shaped block slidingly disposed within the arc-shaped groove; a limit block is installed on one end face of the clamping plate, and a limit groove is opened at the bottom of the annular plate, the limit groove and the limit block being arranged in a one-to-one correspondence, the limit block slidingly disposed within the limit groove; a guide post is installed at the bottom of the clamping plate, and a strip hole is opened around the center of the adjusting ring, the guide post slidingly passing through the strip hole; a protrusion is provided on the outer wall of the end of the clamping plate near the axis of the annular plate, and an adjusting handle is installed on the outer wall of the adjusting ring.

[0012] Furthermore, to enable the height adjustment component to stably adjust the height of the pressing component without affecting the subsequent adjustment of the spacing between different pressing components, the height adjustment component includes a fixed frame mounted on the outer wall of the end block. The fixed frame is U-shaped, and a lead screw is rotatably installed inside the fixed frame. The fixed frame also has a height adjustment block inside, and a threaded sleeve is installed through the height adjustment block. The threaded sleeve is screwed to the outside of the lead screw. A crossbar is provided between the opposite ends of the two height adjustment blocks. A sliding groove is opened at the top of the crossbar. The sliding groove is inverted T-shaped, and a slider is slidably disposed in the sliding groove. The outer diameter of the slider is larger than the width of the top opening of the sliding groove, and the outer diameter of the connecting post is smaller than the outer diameter of the slider and the outer diameter of the connecting post is smaller than the width of the top opening of the sliding groove.

[0013] Furthermore, in order to accurately adjust the horizontal position of both ends of the crossbar synchronously, scale lines are provided on the outer wall of the fixed frame, and pointers are installed on the outer wall of the lifting block.

[0014] Furthermore, in order to enable the push-pull assembly to perform synchronous pressing operations on the extension arm, the push-pull assembly includes a slide rail mounted on the top of the cover plate, a slide block mounted on the slide rail, a transverse plate mounted on the top of the slide block, a connecting frame hinged to the top of the transverse plate, and a connecting rod mounted on the top of the connecting frame. The connecting rod passes through a through hole in the extension arm. An extension plate is provided on one side of the transverse plate, and a threaded sleeve is installed through the extension plate. A positioning screw is threaded through the threaded sleeve. A wear-resistant plate is also installed on the top of the cover plate.

[0015] The beneficial effects of this invention are that it can change the distance between the clamping mechanisms. When it is necessary to inject mud into the lamp tube, the distance between the clamping mechanisms can be increased to provide more operating space for mud injection. When it is not needed, the clamping mechanisms can be brought together, which makes maintenance and other operations more convenient. The space occupied by the clamping mechanisms after they are brought together is also relatively small, and a relatively small protective cover can be used when covering the lamp tube, saving materials. At the same time, the distance between the pressing component used to press the lamp holder and the support frame used to support the lamp tube can also be adjusted, which can effectively clamp lamp tubes of different batches and specifications, improving adaptability.

[0016] The support frame of this invention can change the gap between the ends of the surrounding clamps by rotating the adjusting ring. The change in the gap between the ends of the clamps can correspond to the size of the outer diameter of the lamp tube ends of different specifications, thereby achieving effective support. At the same time, when the ends of the clamps come into contact with the outer wall of the lamp tube ends, they can also have a certain clamping effect, ensuring the stability of the lamp tube ends and providing effective and stable support for pressing the lamp tube tail lamp holder, ensuring the accuracy of subsequent mud injection.

[0017] The height adjustment component of this invention can achieve synchronous height adjustment of the crossbar by adjusting the height of the two height adjustment blocks. When the crossbar is raised or lowered, it can not only drive the slider to rise and fall synchronously through the slide groove, but also the subsequent horizontal movement of the slider following the lifting block does not affect the height adjustment of the crossbar to the lifting block.

[0018] The push-pull assembly of this invention can drive the connecting frame to move synchronously by the horizontal movement of the transverse plate on the top of the cover plate, and the movement adjustment of the connecting rod can be achieved by adjusting the connecting frame. The connecting rod can achieve synchronous adjustment of all the extension arms by connecting the through holes on the extension arms in series. In actual operation, the length of the connecting rod can also be changed to select and connect different numbers of extension arms in series. The unused pressing module will not achieve pressing adjustment. Attached Figure Description

[0050] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0051] Example 1: As Figures 1 to 5 The figure shown is the preferred embodiment of the present invention. A clamping fixture for injecting slurry into lamp tubes includes a base plate 1. An adjustment mechanism 3 is fixedly installed on one side of the top of the base plate 1 via a support rod 2. Several clamping mechanisms 4 are installed on the side of the adjustment mechanism 3 facing directly above the base plate 1. Each clamping mechanism 4 can clamp the lamp tube and the lamp holder. After the clamping is stable, the worker can manually inject slurry into the connection between the lamp tube and the lamp holder. After drying, it can be removed.

[0052] The adjusting mechanism 3 includes two opposing end blocks 31. A vertical plate 32 is fixedly installed on the end of the end block 31 away from the clamping mechanism 4. A rotating roller 33 is rotatably installed between the two end blocks 31. The rotating roller 33 has a number of grooves 331. The number of grooves 331 is equal to the number of clamping mechanisms 4. The grooves 331 are spirally and symmetrically opened on the outer wall of the rotating roller 33. The end of the clamping mechanism 4 facing the rotating roller 33 is slidably connected to the corresponding groove 331. A sliding rod 34 is also fixedly installed between the two end blocks 31. The side of the clamping mechanism 4 near the rotating roller 33 is slidably installed on the sliding rod 34.

[0053] Assuming a rotational force is applied to the rotating roller 33, when the rotating roller 33 rotates, the groove 331 on the outer wall of the rotating roller 33 will adjust the clamping mechanism 4 connected to it. The clamping mechanism 4 will move along the length of the slide rod 34, thereby changing the distance between the clamping mechanisms 4. When mud injection is required for the lamp tube, the distance between the clamping mechanisms 4 will increase, which can facilitate the subsequent mud injection operation. When mud injection is not required, the clamping mechanisms 4 can be adjusted to move closer to each other, which is convenient for cleaning and maintenance.

[0054] A stabilizing rod 35 is also fixedly installed on the side of the two end blocks 31 away from the upright plate 32. The stabilizing rod 35 can improve the connection strength between the end blocks 31.

[0055] A gearbox 36 is installed on the outer wall of any end block 31. A knob is installed on the gearbox 36. The gearbox 36 is connected to the shaft end of the rotating roller 33. The rotation of the rotating roller 33 is controlled by the knob, thereby realizing the position adjustment of the clamping mechanism 4.

[0056] like Figure 6 As shown, the clamping mechanism 4 includes a movable block 41, with a sliding sleeve 42 mounted through it. The sliding sleeve 42 is slidably fitted onto the outside of the slide rod 34. A guide head 43 is mounted on the end face of the movable block 41 facing the rotating roller 33, and the guide head 43 is slidably disposed in a corresponding groove 331. A pressing component 44 is mounted on the top of the end face of the movable block 41 away from the rotating roller 33, and an extension frame 45 is mounted on the bottom of the end face of the movable block 41 away from the rotating roller 33. A support frame 46 is mounted below the end of the extension frame 45 away from the movable block 41. The end of the lamp tube is inserted into the extension frame 45 and placed on the support frame 46. Then, the lamp holder is aligned with the tail of the lamp tube. After that, the pressing component 44 is controlled to press the lamp holder tightly, thus clamping the lamp tube and the lamp holder.

[0057] like Figure 7 As shown, a vertically arranged guide rail 411 is integrally provided on the end face of the moving block 41 away from the rotating roller 33. The pressing component 44 includes a lifting block 441. A guide groove 4411 is opened on the side face of the lifting block 441 facing the moving block 41. The guide rail 411 and the guide groove 4411 are slidably arranged. A pressing module 445 is fixedly installed on the top of the lifting block 441. The lifting block 441 can drive the pressing module 445 to adjust its height, changing the distance between the pressing module 445 and the support frame 46, which can stably clamp lamp tubes and lamp holders of different lengths.

[0058] like Figure 8 As shown, a slot 4412 is provided at the bottom end of the lifting block 441, a locking block 442 is locked in the slot 4412, a connecting post 443 is fixedly installed at the bottom end of the locking block 442, and a slider 444 is fixedly installed at the bottom end of the connecting post 443. Figure 3A height adjustment component 37 is installed on the end face of the end block 31 facing the clamping mechanism 4, and the slider 444 is slidably connected to the height adjustment component 37. The height adjustment component 37 is used to adjust the height of the slider 444. When the height of the slider 444 changes, it can drive the locking block 442 to rise and fall synchronously through the connecting column 443. The locking block 442 then drives the lifting block 441 to change its height through the locking groove 4412, thereby changing the height of the pressing module 445 and realizing the clamping of lamp tubes and lamp holders of different specifications.

[0059] The holding module 445 includes a hinge seat 4451 fixedly installed at the top end of the lifting block 441. A holding arm 4452 is hingedly installed at the top of the hinge seat 4451. An assembly rod 4453 is installed at the end of the holding arm 4452 away from the hinge seat 4451. A holding head 4454 is fixedly installed at the bottom end of the assembly rod 4453. A swing arm 4455 is also hingedly installed on the hinge seat 4451. A connecting arm 4456 is hingedly installed in the middle of the swing arm 4455. The end of the connecting arm 4456 away from the swing arm 4455 is hinged to the middle of the holding arm 4452.

[0060] Applying a force to the swing arm 4455 causes the connecting arm 4456 to move. The connecting arm 4456 then causes the holding arm 4452 to swing relative to the hinge seat 4451. When the assembly rod 4453 at the end of the holding arm 4452 approaches the area where the lamp tube is located, the holding head 4454 at the end of the assembly rod 4453 can press the lamp holder tightly, ensuring that the lamp holder can be tightly pressed against the tail of the lamp tube, which facilitates subsequent mud injection.

[0061] An extension arm 4457 is fixedly mounted on the end of the swing arm 4455 away from the hinge seat 4451. The extension arm 4457 has a through hole 4458. Figure 3 A cover plate 38 is fixedly installed on the top of the two end blocks 31. A push-pull assembly 39 is installed on the cover plate 38. The end of the push-pull assembly 39 away from the cover plate 38 is provided with a through hole 4458. The push-pull assembly 39 can connect all the swing arms 4455 in series, thereby realizing unified synchronous operation and saving the trouble of adjusting the pressure head 4454 individually.

[0062] A limit frame 446 is also fixedly installed on the end face of the lifting block 441 away from the moving block 41. The limit frame 446 is set horizontally in a U-shape. The limit frame 446 can limit the lamp tube. If the lamp tube is accidentally tilted, the limit frame 446 can support it to a certain extent to prevent the lamp tube from tipping over.

[0063] According to the above technical solution, the present invention can change the distance between the clamping mechanisms 4. When it is necessary to inject mud into the lamp tube, the distance between the clamping mechanisms 4 can be increased to provide more operating space for mud injection. When it is not needed, the clamping mechanisms 4 can be brought together, which makes maintenance and other operations more convenient. The space occupied by the clamping mechanisms 4 after they are brought together is also relatively small. When the protective cover is put on, a relatively small protective cover can also be used to save materials. At the same time, the distance between the pressing component 44 used to press the lamp holder and the support frame 46 used to support the lamp tube can also be adjusted, which can effectively clamp lamp tubes of different batches and specifications, improving adaptability.

[0064] Example 2: Figure 9 As shown, an annular sleeve 451 is fixedly installed at the end of the extension frame 45 away from the moving block 41, and a lifting rod 452 is fixedly installed at the bottom end of the annular sleeve 451. A support frame 46 is fixedly installed at the bottom end of the lifting rod 452. The end of the lamp tube passes through the annular sleeve 451 and is placed on the support frame 46, thereby achieving stable support for the end of the lamp tube.

[0065] like Figures 10 to 14 As shown, the support frame 46 includes an annular plate 461 located directly below the annular sleeve 451. The annular plate 461 is coaxially arranged with the annular sleeve 451. The top of the annular plate 461 is fixedly mounted on the lifting rod 452. An assembly frame 464 is fixedly mounted on the outer side of the annular plate 461. An adjusting ring 463 is coaxially arranged directly below the annular plate 461. The bottom outer side of the adjusting ring 463 is connected to the assembly frame 464. A clamping plate 462 is mounted on the top of the adjusting ring 463, and the top of the clamping plate 462 is slidably connected to the annular plate 461. The position of the clamping plate 462 can be changed by adjusting the ring 463, thereby changing the distance between the clamping plate 462 and the center point of the annular plate 461. When the outer wall of the lamp tube end contacts the outer wall of the clamping plate 462 located in the central area of ​​the annular plate 461, support can be achieved for the outer wall of the lamp tube. The change in the position of the clamping plate 462 can effectively support the outer wall of the lamp tube end according to the size of the lamp tube end, and can accommodate more specifications of lamp tubes.

[0066] The assembly frame 464 is C-shaped. The top of the assembly frame 464 is fixedly connected to the outer top of the annular plate 461. The outer side of the adjusting ring 463 is located on the inner bottom wall of the assembly frame 464. An arc-shaped block 4641 is integrally formed on the bottom of the inner wall of the assembly frame 464. An arc-shaped groove 4631 is formed on the outer bottom of the adjusting ring 463, and the arc-shaped block 4641 slides within the arc-shaped groove 4631. The assembly frame 464 not only enables coaxial assembly of the annular plate 461 and the adjusting ring 463 but also ensures stable rotational adjustment of the adjusting ring 463.

[0067] Limiting blocks 4621 are symmetrically installed along the center on one end face of the clamping plate 462 facing the annular plate 461. Limiting grooves 4611 are opened at the bottom of the annular plate 461. The limiting grooves 4611 and the limiting blocks 4621 are set one-to-one. The limiting blocks 4621 are slidably disposed in the limiting grooves 4611. The limiting grooves 4611 are set along the moving direction of the clamping plate 462. A guide post 4622 is fixedly installed at the bottom of the clamping plate 462. A strip hole 4632 is opened on the adjusting ring 463 and is arranged around the center. The guide post 4622 is slidably disposed through the strip hole 4632. When the adjusting ring 463 rotates, it drives the guide post 4622 to move through the strip hole 4632. The guide post 4622 then drives the clamping plate 462 to move synchronously. The top of the clamping plate 462 is limited by the limiting groove 4611 through the limiting block 4621. Therefore, the clamping plate 462 will move along the length direction of the limiting groove 4611, thereby changing the distance of all clamping plates 462 close to the axis of the annular plate 461. The gap between the ends of the clamping plates 462 is used to support the ends of lamp tubes of different specifications.

[0068] A protrusion 4623 is fixedly provided on the outer wall of the end of the clamping plate 462 near the axis of the annular plate 461. The protrusion 4623 can be made of flexible material to avoid damaging the end of the lamp tube. An adjustment handle 4633 is fixedly installed on the outer wall of the adjustment ring 463, and the adjustment ring 463 can be easily rotated by adjusting the handle 4633.

[0069] Through the above technical solution, the support frame 46 provided by the present invention can change the gap between the ends of the clamping plates 462 arranged in a ring by rotating the adjusting ring 463. The change in the gap between the ends of the clamping plates 462 can correspond to the size of the outer diameter of the end of the lamp tube of different specifications, thereby achieving effective support. At the same time, when the end of the clamping plate 462 contacts the outer wall of the end of the lamp tube, it can also have a certain clamping effect, ensuring the stability of the end of the lamp tube, providing effective and stable support for the subsequent pressing of the lamp holder at the tail of the lamp tube, and ensuring the accuracy of subsequent mud injection.

[0070] Example 3: Figures 15 to 16As shown, the height adjustment assembly 37 includes a fixed frame 371 fixedly installed on the outer wall of the end block 31 facing the clamping mechanism 4. The fixed frame 371 is U-shaped. A vertically arranged lead screw 372 is rotatably installed inside the fixed frame 371. The fixed frame 371 also has a height adjustment block 373 inside. A threaded sleeve 374 is installed through the height adjustment block 373. The threaded sleeve 374 is screwed to the outside of the lead screw 372. A crossbar 375 is provided between the opposite ends of the two height adjustment blocks 373. The bottom ends of the crossbar 375 are fixedly installed on the height adjustment blocks 373 on both sides. Rotating the lead screws 372 on both sides allows the lead screws 372 to drive the height adjustment blocks 373 to rise and fall via the lead sleeves 374, thereby changing the height of the crossbar 375. The top of the crossbar 375 has a slide groove 3751 that runs along its length. The slide groove 3751 is inverted T-shaped. The slider 444 is slidably disposed in the slide groove 3751, and the outer diameter of the slider 444 is larger than the width of the top opening of the slide groove 3751. The outer diameter of the connecting post 443 is smaller than the outer diameter of the slider 444, and the outer diameter of the connecting post 443 is smaller than the width of the top opening of the slide groove 3751. When the height adjustment block 373 is raised or lowered, it can drive the crossbar 375 to rise or fall synchronously. The crossbar 375 then drives the slider 444 inside it to rise or fall through the slide groove 3751, thereby realizing the adjustment of the height of all the holding modules 445. The slide groove 3751 also allows the slider 444 to slide inside it. When the moving block 41 is adjusted horizontally, it will drive the lifting block 441 to move synchronously. At this time, the lifting block 441 will drive the slider 444 to slide and adjust within the slide groove 3751 through the bottom locking block 442 and connecting column 443.

[0071] A scale line 376 is provided on the outer wall of the fixed frame 371 on the side away from the crossbar 375. A pointer 377 is fixedly installed on the outer wall of the lifting block 441 on the side near the scale line 376, with the pointer 377 pointing towards the scale line 376. By using the pointer 377 in conjunction with the scale line 376 on the fixed frame 371, the height of the crossbar 375 can be clearly determined, facilitating subsequent synchronous adjustment of the lifting blocks 441 on both sides.

[0072] The top end of the lead screw 372 passes through the top of the fixing bracket 371 and is fixedly mounted with an adjusting handle 378. The lead screw 372 can be easily rotated and adjusted using the adjusting handle 378.

[0073] The height adjustment component 37 in this embodiment can achieve synchronous height adjustment of the crossbar 375 by adjusting the height of the two height adjustment blocks 373. When the crossbar 375 is raised or lowered, it can not only drive the slider 444 to rise or fall synchronously through the slide groove 3751, but also the subsequent horizontal movement of the slider 444 following the lifting block 441 does not affect the height adjustment of the crossbar 375 on the lifting block 441.

[0074] Example 4: Figure 17As shown, the push-pull assembly 39 includes a slide rail 391 fixedly installed on the top of the cover plate 38. The slide rail 391 is arranged along the width direction of the cover plate 38. There are two slide rails 391 arranged parallel to each other. A slide block 392 is slidably installed on the slide rail 391. A transverse plate 393 is fixedly installed between the tops of the slide blocks 392. A connecting frame 394 is hinged to the top of the transverse plate 393. A horizontally arranged connecting rod 395 is installed at the end of the connecting frame 394 away from the transverse plate 393. The connecting rod 395 is provided through the through hole 4458 on the extension arm 4457. Dragging the transverse plate 393 along the length of the slide rail 391 causes the bottom end of the connecting frame 394 to move synchronously. The movement of the connecting frame 394 drives the extension arm 4457 to move synchronously via the connecting rod 395 installed at its top. This allows the extension arm 4457 to adjust the swing arm 4455. Depending on the direction of movement of the transverse plate 393, the connecting frame 394 can be pushed and pulled, which in turn allows the extension arm 4457 to be pressed and raised, ultimately allowing the pressure head 4454 to be raised and lowered, thus enabling the pressure head 4454 to press and release the lamp holder.

[0075] An extension plate 396 is integrally provided on the side of the transverse plate 393 away from the clamping mechanism 4. A threaded sleeve 397 is installed through the extension plate 396, and a positioning screw 398 is screwed through the threaded sleeve 397. A wear-resistant plate 399 is also fixedly installed on the top of the cover plate 38. The wear-resistant plate 399 is arranged along the length of the slide rail 391, and the top of the wear-resistant plate 399 is positioned directly opposite the bottom end of the positioning screw 398. By rotating the positioning screw 398, the bottom end of the positioning screw 398 can be moved toward the wear-resistant plate 399. When the end of the positioning screw 398 contacts the top of the wear-resistant plate 399, the transverse plate 393 can be positioned. This allows the extension arm 4457 to be positioned after the clamping head 4454 presses the lamp holder, preventing the clamping head 4454 from popping up.

[0076] The push-pull assembly 39 in this embodiment can drive the connecting frame 394 to move synchronously by the horizontal movement of the transverse plate 393 on the top of the cover plate 38. The movement of the connecting rod 395 can be adjusted by adjusting the connecting frame 394. The connecting rod 395 can achieve synchronous adjustment of all the extension arms 4457 by connecting the through holes 4458 on the extension arms 4457 in series. In actual operation, the length of the connecting rod 395 can be changed to select and connect different numbers of extension arms 4457 in series. The unused pressing module 445 will not be pressed for adjustment, and the variability is relatively strong.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
