Description

Technical Field

[0001] This invention relates to the field of safety protection equipment, and in particular to a safety helmet for substation operation and maintenance inspection. Background Technology

[0002] Currently, the safety helmets worn during substation operation and maintenance inspections are generally of simple structure, providing only basic protection for the wearer's head. However, during inspections, cameras are typically needed to record the process and pinpoint the current location so that the helmet's position on a map and the camera's range can be displayed in real-time on the backend. Existing technology has the following drawbacks: 1. The cameras and locators fixed to the safety helmets lack protection; they are easily damaged if the helmet falls or collides with other objects. 2. Since the cameras and locators are fixed to the safety helmets, they cannot be used with other safety helmets. Installing cameras and locators on all safety helmets would increase costs for ease of use. Summary of the Invention

[0003] The purpose of this invention is to provide a safety helmet for substation operation and maintenance inspections, which has good inspection effect and low cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A substation maintenance and inspection safety helmet is provided, comprising a helmet body, a brim surrounding the perimeter of the helmet body, and a locking block protruding from the center of the top of the helmet body. The substation maintenance and inspection safety helmet also includes a camera positioning mechanism, which comprises:

[0006] The bracket includes a collar and an arc-shaped frame. The two ends of the arc-length direction of the arc-shaped frame are connected to the opposite sides of the collar. The collar abuts against the brim. The center of the arc-length of the arc-shaped frame is coaxial with the center of the hat body. The arc-shaped center of the arc-shaped frame has an installation groove for the insertion of the locking block.

[0007] A camera positioning component is mounted on the arc-shaped frame;

[0008] The protective cover is made of cushioning material and is placed over the bracket. The protective cover is detachably connected to the bracket. The protective cover is provided with a clearance groove, and the shooting positioning component is located in the clearance groove.

[0009] As a preferred option for a safety helmet for substation operation and maintenance inspection, the outer periphery of the collar has multiple first fixing parts protruding in an annular shape, and fixing holes are opened on the first fixing parts. The protective cover includes a cover body and a fixing ring. The fixing ring is pasted to the open end of the cover body. Multiple fixing studs are provided on the side of the fixing ring opposite to the cover body. The fixing studs pass through the fixing holes and are screwed to the fixing nuts.

[0010] As a preferred embodiment of a safety helmet for substation operation and maintenance inspection, the locking block includes a locking post and a limiting part. One end of the locking post is fixedly connected to the helmet body, and the other end is connected to the limiting part. The mounting groove is provided through the thickness direction of the arc frame. The limiting part is rectangular. The cross-sectional shape of the mounting groove matches the cross-sectional shape of the locking block. After passing through the mounting groove, the limiting part can rotate at a set angle to abut against the side of the arc frame away from the helmet body to prevent the shooting positioning mechanism from separating from the helmet body.

[0011] As a preferred embodiment of the safety helmet for substation operation and maintenance inspection, it also includes a drive component and a switching component. The drive component is mounted on the bracket and is connected to the shooting and positioning component through the switching component. When the switching component is in the first position, the drive component can drive the shooting and positioning component to swing up and down to adjust the angle. When the switching component is in the second position, the drive component can drive the shooting and positioning mechanism to rotate around the periphery of the helmet body.

[0012] As a preferred embodiment of a safety helmet for substation operation and maintenance inspections, the driving component includes a motor, a first gear, a second gear, and a gear ring. The gear ring is fixed on the brim and surrounds the periphery of the helmet body. The shooting and positioning assembly is mounted on a rotating base, which is rotatably mounted on the arc-shaped frame. The rotating base is connected to the first gear, which drives the rotating base to rotate along a first axis. The second gear is rotatably mounted on the bracket and meshes with the gear ring. The second gear drives the shooting and positioning mechanism to rotate along a second axis, which coincides with the central axis of the helmet body. The first axis and the second axis are set at an angle. The switching component selectively connects the driving component to the first gear and the second gear, so that the driving component can selectively drive the first gear and the second gear to rotate.

[0013] As a preferred option for a safety helmet for substation operation and maintenance inspection, the rotating base is rotatably connected to the bracket via a rotating shaft, and the rotating shaft is connected to the first gear via a synchronous belt drive to achieve synchronous rotation.

[0014] As a preferred embodiment of a safety helmet for substation operation and maintenance inspection, the output shaft of the motor is provided with a drive shaft, and the switching component includes a switching gear set. The switching gear set is sleeved on the drive shaft and can rotate synchronously with the drive shaft. The switching gear set can move on the drive shaft and selectively switch to the first position or the second position. When the switching gear set moves to the first position, the switching gear set meshes with the first gear. When the switching gear set moves to the second position, the switching gear set meshes with the second gear.

[0015] As a preferred embodiment of the safety helmet for substation operation and maintenance inspection, the outer side wall of the collar is provided with a second fixing part extending in the horizontal direction, a first sleeve is fixed on the second fixing part, a limit plate is provided at the upper end of the first sleeve, and a through hole is opened in the center of the limit plate.

[0016] The switching gear assembly includes a third gear, a first switching tooth, a second switching tooth, and a second sleeve. One end of the second sleeve is connected to the third gear, and the other end is connected to the first switching tooth. The center of the third gear and the center of the first switching tooth are respectively provided with a first hole and a second hole communicating with the inside of the second sleeve. The drive shaft passes through the first hole, the second sleeve, and the second hole in sequence. The second switching tooth is fixedly connected to the second gear. The third gear is located on the side of the limiting plate away from the first sleeve and can selectively mesh with the first gear. The second sleeve passes through the through hole and is located inside the first sleeve. Both the first switching tooth and the second switching tooth are located inside the first sleeve.

[0017] The switching component further includes a spring, a first magnetic attractor, and a second magnetic attractor. The first magnetic attractor is fixed to the limiting plate and surrounds the through hole. The second magnetic attractor is fixedly connected to the first switching tooth. The spring is disposed between the first switching tooth and the limiting plate. The spring is sleeved on the outside of the second sleeve and always has the ability to drive the first switching tooth to move toward the position where it engages with the second switching tooth. One of the first magnetic attractor and the second magnetic attractor is an electromagnet. When the electromagnet is energized, the first magnetic attractor and the second magnetic attractor overcome the elastic force of the spring and move closer to each other and magnetically attract each other. The first switching tooth separates from the second switching tooth, and the third gear moves to the position where it engages with the first gear.

[0018] As a preferred embodiment of the safety helmet for substation operation and maintenance inspection, both the first gear and the third gear are bevel gears. The rotation axis of the first gear is perpendicular to the rotation axis of the third gear, and the rotation axis of the third gear is coaxial with the rotation axis of the first switching gear, the rotation axis of the second switching gear, and the rotation axis of the second gear.

[0019] As a preferred embodiment of the safety helmet for substation operation and maintenance inspections, the bracket further includes a first mounting base, which is fixed on the arc-shaped frame. The first mounting base includes a base plate and two first connecting plates arranged parallel to one side of the base plate. The rotating seat is rotatably disposed between the two first connecting plates via a rotating shaft; and / or,

[0020] The bracket includes a second mounting base, which is fixed on the second fixing part. The second mounting base includes a top plate and a second connecting plate. The top plate is spaced above the second fixing part, and the second connecting plate connects the top plate and the second fixing part. The motor is mounted on one side of the top plate near the second fixing part.

[0021] The beneficial effects of this invention are as follows: By setting a bracket and a shooting positioning component on the helmet body, the shooting positioning component can transmit the position of the safety helmet and the camera content to the backend, which is convenient for the backend to monitor. The protective cover made of cushioning material can protect the shooting positioning component and effectively prevent damage to the shooting positioning component. The protective cover can also provide secondary protection for the wearer's head inside the helmet body, reducing the vibration during impact. By setting the bracket, shooting positioning component and protective cover as a detachable connection structure, the assembly difficulty of the entire shooting positioning mechanism can be reduced. The shooting positioning mechanism composed of the bracket, shooting positioning component and protective cover can also be detached relative to the helmet body. When the safety helmet is damaged or needs to be replaced, this shooting positioning mechanism can be removed and used on other helmet bodies, which increases versatility and reduces costs. Moreover, by setting a locking block and mounting slot, the shooting positioning mechanism can be fixed in position relative to the helmet body with simple plug-in, making the operation very simple.

[0032] The advantages and features of the present invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of the invention and to enable those skilled in the art to fully understand the scope of the invention, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2As shown, the substation maintenance and inspection safety helmet of the present invention includes a helmet body 1, a brim 2 surrounding the periphery of the helmet body 1, and a locking block 11 protruding from the center of the top of the helmet body 1. The substation maintenance and inspection safety helmet also includes a shooting and positioning mechanism, which includes a bracket 3, a shooting and positioning component 4, and a protective cover 5. The bracket 3 includes a collar 31 and an arc-shaped frame 32. The two ends of the arc length direction of the arc-shaped frame 32 are connected to the opposite sides of the collar 31. 31 abuts against the brim 2. The arc length center of the arc frame 32 is coaxial with the center of the hat body 1. The arc center of the arc frame 32 is provided with an installation groove 321 for the insertion of the card block 11. The shooting positioning component 4 is disposed on the arc frame 32. The protective cover 5 is made of cushioning material. The protective cover 5 covers the outside of the bracket 3. The protective cover 5 is detachably connected to the bracket 3. The protective cover 5 is provided with an avoidance groove 51. The shooting positioning component 4 is located in the avoidance groove 51. By setting a bracket 3 and a shooting positioning component 4 on the helmet body 1, the shooting positioning component 4 can transmit the position of the safety helmet and the camera content to the backend for easy monitoring. The protective cover 5, made of cushioning material, can protect the shooting positioning component 4 and effectively prevent damage to it. The protective cover 5 can also provide secondary protection for the wearer's head inside the helmet body 1, reducing vibration during impact. By setting the bracket 3, shooting positioning component 4 and protective cover 5 as a detachable connection structure, the assembly difficulty of the entire shooting positioning mechanism can be reduced. The shooting positioning mechanism composed of the bracket 3, shooting positioning component 4 and protective cover 5 can also be detached relative to the helmet body 1. When the safety helmet is damaged or needs to be replaced, this shooting positioning mechanism can be removed and used on other helmet bodies 1, increasing versatility and reducing costs. Furthermore, by setting a locking block 11 and a mounting slot 321, the shooting positioning mechanism can be fixed in position relative to the helmet body 1 with simple plugging, making the operation very simple.

[0035] In this embodiment, the shooting and positioning component 4 includes a camera 41 and a locator 42. Both the camera 41 and the locator 42 are connected to a controller (not shown in the figure). The controller transmits signals to the main control backend via a wireless transmission module to transmit the captured video or photos to the main control backend in real time. The main control backend can also locate the specific position of the current substation operation and maintenance inspection safety helmet based on the location information transmitted back by the locator 42, so as to determine whether the inspection route is correct.

[0036] In one embodiment, the outer periphery of the collar 31 has a plurality of first fixing portions 33 protruding in an annular shape. The first fixing portions 33 have fixing holes 331. The protective cover 5 includes a cover body 52 and a fixing ring 53. The fixing ring 53 is attached to the open end of the cover body 52. ​​A plurality of fixing studs 54 protrude from the side of the fixing ring 53 facing away from the cover body 52. ​​The fixing studs 54 pass through the fixing holes 331 and are screwed onto a fixing nut 55. By providing the fixing ring 53, the soft parts of the protective cover 5 can be prevented from directly connecting to the collar 31, thus avoiding connection failure. Preferably, the cover body 52 of the protective cover 5 is made of materials such as cushioning foam or silicone.

[0037] In addition to setting a fixing stud 54 on the fixing ring 53, screws can be directly used to connect the fixing ring 53 and the first fixing part 33. Alternatively, a snap-fit ​​connection can be used to connect the first fixing part 33 and the fixing ring 53.

[0038] In one embodiment, such as Figures 2 to 4 As shown, the locking block 11 includes a locking post 111 and a limiting part 112. One end of the locking post 111 is fixedly connected to the cap body 1, and the other end is connected to the limiting part 112. The mounting groove 321 is provided through the arc frame 32 along its thickness direction. The limiting part 112 is rectangular, and the cross-sectional shape of the mounting groove 321 matches the cross-sectional shape of the locking block 11. After passing through the mounting groove 321, the limiting part 112 can rotate a set angle to abut against the side of the arc frame 32 away from the cap body 1, thus preventing the shooting positioning mechanism from separating from the cap body 1. By providing a through mounting groove 321 that matches the cross-sectional shape of the locking block 11, the limiting part 112 of the locking block 11 only needs to rotate a certain angle after passing through the mounting groove 321 to abut against the side of the arc frame 32 away from the cap body 1, effectively preventing the shooting positioning mechanism from separating from the cap body 1. Installation and disassembly are very simple.

[0039] In this embodiment, the shooting positioning mechanism can be rotated relative to the cap body 1, and the shooting positioning component 4 can be positioned in the horizontal direction to capture a wider range of images.

[0040] In one embodiment, such as Figures 1 to 7 As shown, the position of the shooting positioning component 4 in the horizontal direction and the angle of the shooting positioning component 4 swinging up and down are adjusted by automatic control.

[0041] In this embodiment, the shooting positioning mechanism further includes a driving component 6 and a switching component 7. The driving component 6 is mounted on the bracket 3 and is connected to the shooting positioning assembly 4 via the switching component 7. When the switching component 7 is in the first position, the driving component 6 can drive the shooting positioning assembly 4 to swing up and down to adjust its angle. When the switching component 7 is in the second position, the driving component 6 can drive the entire shooting positioning mechanism to rotate around the circumference of the cap body 1. By setting the switching component 7, a single driving component 6 can drive the shooting positioning assembly to both rotate horizontally and swing vertically to adjust its position, effectively reducing the number of driving components 6 and lowering costs.

[0042] In this embodiment, the driving component 6 includes a motor 61, a first gear 62, a second gear 63, and a gear ring 64. The gear ring 64 is fixed to the brim 2 and surrounds the periphery of the hat body 1. The shooting positioning component 4 is mounted on a rotating seat 8, which is rotatably mounted on the arc-shaped frame 32. The rotating seat 8 is connected to the first gear 62, which drives the rotating seat 8 to rotate along a first axis. The second gear 63 is rotatably mounted on the bracket 3 and meshes with the gear ring 64. The second gear 63 drives the shooting positioning mechanism to rotate along a second axis, which coincides with the central axis of the hat body 1. The first axis and the second axis are set at an angle. The switching component 7 selectively connects the driving component 6 to the first gear 62 and the second gear 63, so that the driving component 6 can selectively drive the first gear 62 and the second gear 63 to rotate. The gear transmission is more stable and reliable, less prone to shaking, and ensures the shooting quality of the camera 41.

[0043] Preferably, the rotating seat 8 is rotatably connected to the bracket 3 via a rotating shaft 66, and the rotating shaft 66 is connected to the first gear 62 via a synchronous belt 67 to achieve synchronous rotation.

[0044] In this embodiment, a drive shaft 65 is provided at the output shaft end of the motor 61. The switching component 7 includes a switching gear set 71, which is sleeved on the drive shaft 65 and can rotate synchronously with the drive shaft 65. The switching gear set 71 can move on the drive shaft 65 to selectively switch to the first position or the second position. When the switching gear set 71 moves to the first position, it meshes with the first gear 62. When the switching gear set 71 moves to the second position, it meshes with the second gear 63. The moving switching gear set 71 can mesh with the first gear 62 and the second gear 63 as needed, thereby realizing the position adjustment of the positioning component 4 in different directions. The switching process is simple.

[0045] Specifically, the outer side wall of the collar 31 is provided with a second fixing part 34 extending horizontally, and a first sleeve 35 is fixed on the second fixing part 34. A limiting plate 36 is provided at the upper end of the first sleeve 35, and a through hole 361 is formed in the center of the limiting plate 36. The switching gear assembly 71 includes a third gear 711, a first switching tooth 712, a second switching tooth 713, and a second sleeve 714. One end of the second sleeve 714 is connected to the third gear 711, and the other end is connected to the first switching tooth 712. The center of the third gear 711 and the center of the first switching tooth 712 are connected to each other. The center of 12 is provided with a first hole and a second hole that communicate with the inside of the second sleeve 714. The drive shaft 65 passes through the first hole, the second sleeve 714 and the second hole in sequence. The second switching tooth 713 is fixedly connected to the second gear 63. The third gear 711 is located on the side of the limiting plate 36 away from the first sleeve 35 and can selectively mesh with the first gear 62. The second sleeve 714 passes through the through hole 361 and is located inside the first sleeve 35. The first switching tooth 712 and the second switching tooth 713 are both located inside the first sleeve 35.

[0046] The switching component 7 further includes a spring 72, a first magnetic 73, and a second magnetic 74. The first magnetic 73 is fixed on the limiting plate 36 and surrounds the through hole 361. The second magnetic 74 is fixedly connected to the first switching tooth 712. The spring 72 is disposed between the first switching tooth 712 and the limiting plate 36. The spring 72 is sleeved on the outside of the second sleeve 714, and the spring 72 always has the ability to drive the first switching tooth 712 to move toward the position of engaging with the second switching tooth 713. One of the first magnetic 73 and the second magnetic 74 is an electromagnet. When the electromagnet is energized, the first magnetic 73 and the second magnetic 74 overcome the elastic force of the spring 72 and move closer to each other and magnetically attract each other. The first switching tooth 712 separates from the second switching tooth 713, and the third gear 711 moves to the position of engaging with the first gear 62.

[0047] Specifically, when it is necessary to adjust the up-and-down shooting angle of the camera 41 of the shooting positioning component 4, the controller controls the electromagnet to be energized, and the first magnetic suction member 73 and the second magnetic suction member 74 are magnetically attracted together over the elastic force of the spring 72. At this time, the second magnetic suction member 74 drives the first switching tooth 712 to separate from the second switching tooth 713. Since the third gear 711, the first switching tooth 712 and the second sleeve 714 are connected as a whole structure, this whole structure will move upward along the drive shaft 65, so that the third gear 711 can move to the position of meshing with the first gear 62. The motor 61 starts, and the motor 61 drives the drive shaft 65 to rotate. The drive shaft 65 drives the whole structure to rotate synchronously, so that the third gear 711 rotates. The third gear 711 then drives the first gear 62 to rotate. With the cooperation of the synchronous belt 67, the rotating seat 8 drives the camera 41 to swing up and down. Whether the swing direction is upward or downward is achieved by the forward or reverse rotation of the motor 61.

[0048] When it is necessary to adjust the shooting angle of the camera 41 of the shooting positioning component 4 in the horizontal direction, the electromagnet is de-energized, and the first magnetic 73 and the second magnetic 74 lose their magnetic attraction. At this time, the spring 72 pushes the first magnetic 73 and the second magnetic 74 apart, so that the second magnetic 74 drives the first switching tooth 712 to move downward and engage with the second switching tooth 713. At this time, the third gear 711 is separated from the first gear 62 because the overall structure has moved downward a certain distance. The motor 61 starts and drives the drive shaft 65 to rotate. The drive shaft 65 drives the overall structure to rotate synchronously, so that the third gear 711 rotates, so that the first switching tooth 712 drives the second switching tooth 713 to rotate, and the second switching tooth 713 drives the second gear 63 to rotate. Since the second gear 63 is engaged with the gear ring 64, the entire shooting positioning mechanism rotates relative to the cap body 1, thereby realizing the adjustment of the shooting angle of the camera 41 in the horizontal direction.

[0049] The electromagnet can be easily switched between two different positions by turning the switching component 7 on and off. This allows the entire structure consisting of the third gear 711, the second sleeve 714, and the first switching tooth 712 to move vertically to switch positions. The components are simple, the switching process is smooth, and the operation difficulty is effectively reduced.

[0050] Preferably, both the first gear 62 and the third gear 711 are bevel gears. The rotation axis of the first gear 62 is perpendicular to the rotation axis of the third gear 711, and the rotation axis of the third gear 711 is coaxial with the rotation axes of the first switching gear 712, the second switching gear 713, and the second gear 63. To save space and reduce the area occupied by the switching element 7, the first gear 62 and the third gear 711 are set as bevel gears.

[0051] More preferably, the first switching tooth 712 and the second switching tooth 713 have similar structures, both having annular toothed structures on one side of a circular plate-shaped body. The toothed structures of the first switching tooth 712 and the second switching tooth 713 are arranged opposite to each other and can selectively mesh.

[0052] For ease of installation, the limiting plate 36 can also be configured to be detachably connected to the first sleeve 35.

[0053] In addition, the drive shaft 65 has a square cross-section, and the cross-sections of the first hole, the second hole, and the inner hole of the corresponding switching gear set 71 and the second sleeve 714 are also square. This design enables the drive shaft 65 to drive the switching gear set 71 to rotate, and also enables the switching gear set 71 to move on the drive shaft 65.

[0054] In one embodiment, in order to make the entire shooting positioning mechanism rotate more smoothly, a plurality of balls 39 are arranged in a ring at intervals on one side of the collar 31 of the bracket 3 that abuts against the brim 2. The balls 39 can reduce the friction between the collar 31 and the brim 2 when moving, making the rotation smoother.

[0055] In one embodiment, such as Figure 3 and Figure 4 As shown, the bracket 3 also includes a first mounting base 37 and a second mounting base 38. The first mounting base 37 is fixed on the arc-shaped frame 32. The first mounting base 37 includes a base plate 371 and two first connecting plates 372 arranged parallel to one side of the base plate 371. The rotating seat 8 is rotatably disposed between the two first connecting plates 372 via a rotating shaft 66. The second mounting base 38 is fixed on the second fixing part 34. The second mounting base 38 includes a top plate 381 and a second connecting plate. The top plate 381 is spaced apart above the second fixing part 34. The second connecting plate connects the top plate 381 and the second fixing part 34. The motor 61 is mounted on one side of the top plate 381 near the second fixing part 34.

[0056] In addition, the first mounting base 37 and the second mounting base 38 of the bracket 3, the shooting positioning component 4, the driving component 6, the switching component 7 and the rotating base 8 are all located in the relief groove 51, that is, they will not protrude outward from the outer surface of the protective cover 5. This design can protect the structure that is directly connected or indirectly connected to the shooting positioning component 4 by the protective cover 5, effectively avoiding damage.

[0057] Although embodiments of the invention have been described above with reference to the accompanying drawings, the invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.

The driving component includes a motor, a first gear, a second gear, and a gear ring. The gear ring is fixed to the brim and surrounds the periphery of the hat body. The shooting positioning component is mounted on a rotating base, which is rotatably mounted on the arc-shaped frame. The rotating base is connected to the first gear, which drives the rotating base to rotate along a first axis. The second gear is rotatably mounted on the bracket and meshes with the gear ring. The second gear drives the shooting positioning mechanism to rotate along a second axis, which coincides with the central axis of the hat body. The first axis and the second axis are set at an angle. The switching component selectively connects the driving component to the first gear and the second gear, so that the driving component can selectively drive the first gear and the second gear to rotate. The motor has a drive shaft at its output shaft end. The switching component includes a switching gear set, which is sleeved on the drive shaft and can rotate synchronously with the drive shaft. The switching gear set can move on the drive shaft and selectively switch to the first position or the second position. When the switching gear set moves to the first position, it meshes with the first gear. When the switching gear set moves to the second position, it meshes with the second gear. The outer side wall of the collar is provided with a second fixing part that extends horizontally. A first sleeve is fixed on the second fixing part. A limit plate is provided at the upper end of the first sleeve. A through hole is opened in the center of the limit plate. The switching gear assembly includes a third gear, a first switching tooth, a second switching tooth, and a second sleeve. One end of the second sleeve is connected to the third gear, and the other end is connected to the first switching tooth. The center of the third gear and the center of the first switching tooth are respectively provided with a first hole and a second hole communicating with the inside of the second sleeve. The drive shaft passes through the first hole, the second sleeve, and the second hole in sequence. The second switching tooth is fixedly connected to the second gear. The third gear is located on the side of the limiting plate away from the first sleeve and can selectively mesh with the first gear. The second sleeve passes through the through hole and is located inside the first sleeve. Both the first switching tooth and the second switching tooth are located inside the first sleeve. The switching component further includes a spring, a first magnetic attractor, and a second magnetic attractor. The first magnetic attractor is fixed to the limiting plate and surrounds the through hole. The second magnetic attractor is fixedly connected to the first switching tooth. The spring is disposed between the first switching tooth and the limiting plate. The spring is sleeved on the outside of the second sleeve and always has the ability to drive the first switching tooth to move toward the position where it engages with the second switching tooth. One of the first magnetic attractor and the second magnetic attractor is an electromagnet. When the electromagnet is energized, the first magnetic attractor and the second magnetic attractor overcome the elastic force of the spring and move closer to each other and magnetically attract each other. The first switching tooth separates from the second switching tooth, and the third gear moves to the position where it engages with the first gear.
