An arc-shaped pull plate 47 is sleeved, and the end of the arc-shaped pull plate 47 is rotatably inserted with a second rotating shaft 48, one end of the second rotating shaft 48 is rotatably sleeved with a rotating guard plate 49, and adjacent rotating guard plates 49 can fit tightly, a third rotating shaft 410 is rotatably inserted on the rotating guard plate 49, and the third rotating shaft 410 is rotatably inserted on the connecting bottom ring 31, a cleaning cotton brush 411 is fixedly installed on the top of the rotating guard plate 49, and the cleaning cotton brush 411 can fit tightly with the bottom end of the laser locator 2, the connecting bottom ring 31 is integrally formed with a first side plate 39 and a second side plate 310 for use together, and the driving rotating rod 42 is rotatably inserted on the first side plate 39, and a driving hand wheel 416 is fixedly sleeved on the top of the driving rotating rod 42, and the setting of the driving hand wheel 416 is used to drive the rotating rod 42.

[0024] By adopting the above technical solution, when in use, the two T-shaped rotating tubes 35 are rotated at the same time, so that the corresponding limiting rotating rod 34 can be driven to rotate and twist the corresponding limiting torsion spring 36, and then the corresponding limiting clamping block 37 can be driven to rotate, and the rotation of the T-shaped rotating tube 35 is stopped when the limiting clamping block 37 rotates forty-five degrees, and then the two limiting clamping blocks 37 are aligned with the corresponding limiting through-slots 11 and inserted, until the limiting clamping block 37 passes through the corresponding limiting through-slots 11 and the upper end of the T-shaped rotating tube 35 is stuck in the corresponding limiting through-slots 11, and the two T-shaped rotating tubes 35 are released in turn. At this time, the limiting torsion spring 36 will drive the corresponding T-shaped rotating tube 35 to reverse and reset.

When the industrial robot positioning module needs to display the working area at the bottom end of the laser locator 2 during teaching, the user needs to push the fixed gear 415 to the side close to the fixed collar 413, so as to squeeze the fixed spring 414 and make the fixed gear 415 gradually separate from the driven gear ring 41. When the fixed gear 415 When it is completely separated from the driven ring gear 41, stop pushing the fixed gear 415 and turn the driving hand wheel 416, so that the driving gear 412 can be driven to rotate through the driving rotating rod 42, and then the driven ring gear 41 can be driven to rotate, and the driving pull plate 45 can be driven to rotate through the internal rotating ring 44, so that the corresponding arc-shaped pull plate 47 can be pulled to rotate through the first rotating shaft 46, and then the five rotating guard plates 49 can be synchronously pulled to rotate and diverge outwards through the cooperation of the second rotating shaft 48 and the third rotating shaft 410, and further the five cleaning cotton brushes 411 can be driven to rotate and diverge outwards synchronously, so that the laser fixed The bottom working area of ​​the laser locator 2 can be effectively cleaned and can be gradually exposed. After the bottom working area of ​​the laser locator 2 is completely exposed, stop rotating the driving hand wheel 416 and release the fixed gear 415. Then the fixed spring 414 will drive the fixed gear 415 to reset, so that it can mesh with the driven gear ring 41 again and fix it in a limited position. Then the exposed and cleaned bottom working area of ​​the laser locator 2 can be provided to the user for teaching demonstration. After the teaching work is completed, the rotating guard plate 49 and the cleaning cotton brush 411 can be rotated inward, gathered and fixed according to the above steps.

[0025] The protection mechanism 5 includes a protection rotating rod 51, which is connected to the bottom ring 31 and has two third side plates 311 integrally formed thereon, and a first rotating seat 312 is fixedly installed at the bottom end of the third side plate 311, and the protection rotating rod 51 is rotatably inserted on the first rotating seat 312, and both ends of the protection rotating rod 51 are fixedly sleeved with protection arrow-shaped plates 52, and the setting and use of the protection arrow-shaped plates 52 facilitates their rotation when they come into contact with the ground, and protection torsion springs 53 are fixedly installed on the opposite sides of adjacent protection arrow-shaped plates 52, and the end of the protection torsion spring 53 away from the protection arrow-shaped plate 52 is fixedly connected to the first rotating seat 312.

[0026] By adopting the above technical solution, when in use, when the positioning module falls and contacts the ground, the protective arrow-shaped plate 52 in contact with the ground will rotate rapidly, thereby being able to twist the corresponding protective torsion spring 53, and then the reaction force generated when the positioning module hits the ground can be effectively converted into the torque required for twisting the protective torsion spring 53, thereby effectively reducing the damage to the positioning module caused by falling and hitting the ground.

[0027] The deceleration mechanism 6 includes a second rotating seat 61, which is fixedly mounted on both sides of the connecting bracket 1, and an installation rotating rod 62 is rotatably inserted on the adjacent second rotating seat 61, and a deceleration rotating frame 63 is rotatably sleeved on the middle part of the installation rotating rod 62, and the deceleration rotating frame 63 can fit with the connecting bracket 1, and the end of the deceleration rotating frame 63 away from the installation rotating rod 62 is integrally formed with a wind collecting guide frame 67 for use, and the setting and use of the wind collecting guide frame 67 facilitates the rapid collection of gas, and reset torsion springs 64 are fixedly mounted on both sides of the end of the deceleration rotating frame 63 close to the installation rotating rod 62, and the end of the reset torsion spring 64 away from the deceleration rotating frame 63 is fixedly connected to the second rotating seat 61, and a mounting through groove 65 is opened through the deceleration rotating frame 63, and a deceleration umbrella body 66 is fixedly mounted in the mounting through groove 65.

[0028] By adopting the above technical solution, when in use, when the positioning module falls out of hand, air will be quickly introduced into the space between the deceleration rotating frame 63 and the connecting bracket 1, thereby pushing the deceleration rotating frame 63 to rotate and twist the corresponding return torsion spring 64. When the deceleration rotating frame 63 rotates and unfolds, the air will flow into the deceleration parachute 66 and pass through the installation slot 65 to unfold, thereby being able to reduce the descent speed of the positioning module with the help of air resistance, and further effectively reduce the impact force generated when the positioning module falls to the ground.

[0029] Working principle: when in use, the two T-shaped rotating tubes 35 are rotated at the same time, thereby driving the corresponding limiting rotating rod 34 to rotate and twisting the corresponding limiting torsion spring 36, thereby driving the corresponding limiting clamping block 37 to rotate, and the T-shaped rotating tube 35 is stopped when the limiting clamping block 37 rotates forty-five degrees, and then the two limiting clamping blocks 37 are aligned with the corresponding limiting through-slot 11 and inserted, until the limiting clamping block 37 passes through the corresponding limiting through-slot 11 and the upper end of the T-shaped rotating tube 35 is stuck in the corresponding limiting through-slot 11, and the two T-shaped rotating tubes 35 are released in sequence, at this time, the limiting torsion spring 36 will drive the corresponding T-shaped rotating tube 35 to reverse and reset, thereby driving the corresponding limiting clamping block 37 to reverse and reset through the corresponding limiting rotating rod 34, thereby making the limiting clamping block 37 misaligned with the corresponding limiting through-slot 11, and further, the connecting bottom ring 31 can be conveniently fixed on the connecting bracket 1, and at this time, the cleaning cotton brush 411 will fit with the bottom end of the laser locator 2; When the industrial robot positioning module needs to display the working area at the bottom of the laser locator 2 during teaching, the user needs to push the fixed gear 415 to the side close to the fixed collar 413, so as to squeeze the fixed spring 414 and gradually separate the fixed gear 415 from the driven gear ring 41. When the fixed gear 415 is completely separated from the driven gear ring 41, stop pushing the fixed gear 415 and turn the driving hand wheel 416, so as to drive the driving gear 412 to rotate through the driving rotating rod 42, and then drive the driven gear ring 41 to rotate, and further drive the driving pull plate 45 to rotate through the internal rotating ring 44, so as to pull the corresponding arc pull plate 47 to rotate through the first rotating shaft 46, and then can be synchronously pulled through the cooperation of the second rotating shaft 48 and the third rotating shaft 410. The five rotating guard plates 49 are driven to rotate outwards and diverge, which can further drive the five cleaning cotton brushes 411 to rotate outwards and diverge synchronously, so that the working area at the bottom end of the laser locator 2 can be effectively cleaned, and the working area at the bottom end of the laser locator 2 can be gradually exposed, until the working area at the bottom end of the laser locator 2 is completely exposed, the driving hand wheel 416 is stopped and the fixed gear 415 is released, and then the fixed spring 414 drives the fixed gear 415 to reset, so that it can mesh with the driven gear ring 41 again and limit and fix it, and then the exposed and cleaned working area at the bottom end of the laser locator 2 can be provided to the user for teaching and demonstration, and after the teaching operation is completed, the rotating guard plate 49 and the cleaning cotton brush 411 can be rotated inwards, gathered together and fixed according to the above steps; During teaching, when the positioning module falls off, air will be quickly introduced between the deceleration rotating frame 63 and the connecting bracket 1, so as to push the deceleration rotating frame 63 to rotate and twist the corresponding reset torsion spring 64. When the deceleration rotating frame 63 rotates and unfolds, the air will flow into the deceleration parachute 66 and pass through the installation slot 65 to unfold, so as to reduce the descent speed of the positioning module with the help of air resistance, and further effectively reduce the impact force generated when the positioning module falls to the ground, so as to provide good protection for the positioning module, thereby extending the service life of the positioning module for teaching industrial robots and reducing teaching expenses. At the same time, when the positioning module falls and contacts the ground, the protective arrow-shaped plate 52 in contact with the ground will rotate rapidly, thereby being able to twist the corresponding protective torsion spring 53, and then effectively convert the reaction force generated when the positioning module hits the ground into the torque required for the twisting of the protective torsion spring 53, thereby effectively reducing the damage to the positioning module caused by falling and hitting the ground, thereby further extending the service life of the positioning module for industrial robot teaching and further reducing teaching expenses.
