Technical Field

[0001] This invention relates to an emergency jump starter for automobiles, and more particularly to a retractable jump starter for automobiles. Background Technology

[0002] In daily life, some people frequently use cars, but sometimes car batteries may become low on charge. A low car battery can prevent the car from starting, requiring the use of a car jump starter to recharge it.

[0003] Chinese patent application CN202010037249.5 discloses a car emergency jump starter with preheating function, relating to the field of car emergency jump starter technology. It includes a power supply body, a handle, and a heating sleeve assembly. The power supply body includes an electric heater, a controller, and a battery pack. A heating chamber is located on one side of the power supply body, housing a heating sleeve. The heating sleeve has a "T"-shaped blanket structure with heating wires on its inner surface. The heating sleeve, electric heater, and battery pack are electrically connected to each other. This patent solves the problem of power supply failure under low-temperature conditions through the heating sleeve and electric heater; it preheats the target power source through the electrical connection between the emergency power supply and the electric heater and heating sleeve; and the heating chamber facilitates the retrieval of the heating sleeve, reducing its size and space occupation. While the patent can charge car batteries, it is inconvenient to store them after charging, affecting subsequent use.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a retractable car emergency jump starter is proposed, which can be easily stored and does not affect subsequent use. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which, although capable of charging car batteries, are inconvenient to store after charging and affect subsequent use, this invention provides a retractable car emergency jump starter that is easy to store and does not affect subsequent use.

[0006] This invention is achieved through the following technical means:

[0007] A retractable car jump starter includes a car jump starter, an n-shaped frame, a housing, a clamping mechanism, and a power-on mechanism. The n-shaped frame is fixedly connected to the top center of the car jump starter. The housing is fixedly connected between the lower part of the outer rear side of the n-shaped frame and the rear side of the car jump starter. The clamping mechanism for clamping onto the positive and negative terminals of a car battery is installed on the upper part of the n-shaped frame. The power-on mechanism for energizing the clamping mechanism is installed inside the n-shaped frame. The power-on mechanism is connected to the clamping mechanism.

[0008] To further explain, the clamping mechanism includes an L-shaped shell, a clamping frame, an arc-shaped conductive rod, and a first spring. The upper part of the front and rear sides of the L-shaped frame has slots, in which the L-shaped shell is slidably placed. The L-shaped shell is connected to the energizing mechanism. The clamping frame for clamping is rotatably connected to the top inner side of the L-shaped shell. The lower part of the outer side of the front and rear clamping frames is connected to the inner side of the L-shaped shell on the same side, and the arc-shaped conductive rod is fixed to the lower part of the outer side of the front and rear clamping frames.

[0009] To further explain, the energizing mechanism includes a wire, a shaft, a winding wheel, a spiral spring, and an iron plate. The shaft is symmetrically connected to the left and right sides of the n-shaped frame, rotating back and forth. A winding wheel is fixed in the middle of the shaft, and a wire is wound on the winding wheel. One end of the wire passes through the n-shaped frame and is connected to the car's emergency jump starter. The other end of the wire passes through the n-shaped frame and the L-shaped shell, and is fixed to an iron plate for guiding the current into the arc-shaped conductive rod. The iron plate is fixedly connected to the L-shaped shell on the same side. Spiral springs are connected between the middle of the left and right sides of the winding wheel and the left and right sides of the n-shaped frame, respectively. The spiral springs are sleeved on the shaft.

[0010] Further explanation: It also includes a drive mechanism for swinging the clamping frame downwards. The drive mechanism includes a swing plate, a rotating rod, an arc-shaped trigger rod, a first rack, a first gear, and a second spring. The first gear is connected between the upper outer sides of the left and right sides inside the clamping frame. The first rack, which drives the first gear to rotate inwards, is slidably connected to the top center of the L-shaped shell. The first rack meshes with the first gear. The outer sides of the first rack on the front and rear sides are connected to the inner sides of the L-shaped shell on the front and rear sides, respectively, and the lower outer sides of the first rack on the front and rear sides are respectively connected to the inner sides of the L-shaped shell. The lower outer sides of the first rack on the front and rear sides are fixedly connected to the arc-shaped trigger rod. The lower sides of the left and right sides inside the L-shaped shell are rotatably connected to the rotating rod. A swing plate for driving the arc-shaped trigger rod to move inwards is fixedly fitted between the two rotating rods. The lower part of the swing plate penetrates the L-shaped shell, and the top of the swing plate contacts the bottom end of the arc-shaped trigger rod.

[0011] Further explanation: It also includes a limiting mechanism for limiting the L-shaped shell. This limiting mechanism includes an L-shaped limiting plate, connecting rods, a second rack, a second gear, an L-shaped rack, a movable plate, a guide rod, and a third spring. L-shaped limiting plates for limiting the L-shaped shell are embedded and slidably connected to the upper part of both the front and rear sides of the n-shaped frame. The top of the L-shaped limiting plate penetrates the n-shaped frame and is located in a slot. Two connecting rods are fixedly connected between the lower part of the rear side of the front L-shaped limiting plate and the lower part of the front side of the rear L-shaped limiting plate, penetrating the n-shaped frame. A second rack is fixedly connected to the middle of the rear side of the rear L-shaped limiting plate, located inside the shell. The second rack has two... A second gear is rotatably connected between the upper sides to drive the second rack downwards. The second gear meshes with the second rack. An L-shaped rack is slidably connected to the middle of the rear side of the bottom of the housing to drive the second gear to reverse. The L-shaped rack meshes with the second gear. Guide rods are symmetrically embedded and slidably connected on both the front and rear sides of the bottom of the car emergency jump starter. A movable plate is fixedly connected between the bottom ends of the four guide rods. The middle of the rear side of the movable plate is fixedly connected to the front end of the L-shaped rack. A third spring is symmetrically connected on both the front and rear sides of the top of the movable plate. The third spring is sleeved on the guide rod, and the tail end of the third spring is fixedly connected to the bottom of the car emergency jump starter.

[0012] To further explain, it also includes a sliding plate and a ceramic ring. The sliding plate is symmetrically embedded in the middle of the top of the n-shaped frame. A ceramic ring for guiding the wire is fixedly connected in the middle of the sliding plate, and the wire passes through the ceramic ring.

[0013] Further explanation: It also includes a contact plate, a fourth spring, and a locking rod. A limiting groove is opened in the middle of the bottom of the swing plate. The contact plate is slidably connected to the bottom of the L-shaped shell. The contact plate contacts the locking groove. The fourth spring is symmetrically connected between the top of the contact plate and the inner side of the L-shaped shell. A locking rod for limiting the swing plate is fixed in the middle of the inner side of the top of the contact plate. The top of the locking rod passes through the L-shaped shell and is located in the limiting groove.

[0014] To further explain, rubber sleeves are fixed to the lower part of the outer side of the L-shaped shell on both the left and right sides.

[0015] The significant advancement of this invention lies in:

[0016] 1. Pull the clamping mechanism outward to disengage it from the N-shaped frame, then pull the clamping mechanism to clamp onto the positive and negative terminals of the car battery. The clamping mechanism also drives the energizing mechanism to move. Turn on the car's emergency jump starter to input current into the energizing mechanism. The current in the energizing mechanism is then input into the car battery through the clamping mechanism. After charging is complete, insert the clamping mechanism back into the N-shaped frame. This makes it easy to store and does not affect subsequent use.

[0017] 2. Under the action of the drive mechanism, whenever the L-shaped shell disengages from the slot, the operator can pull the drive mechanism to swing the clamping frame downwards a certain distance. In this way, the operator does not need to manually pull the clamping frame downwards a certain distance, which is convenient and quick.

[0018] 3. Under the action of the limiting mechanism, the limiting mechanism can limit the L-shaped shell to prevent the L-shaped shell from separating from the slot. In this way, when the car emergency jump starter is moved, the L-shaped shell can be prevented from separating from the slot and falling down, thus affecting the movement.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, and embodiments of the present invention will be given with reference to the accompanying drawings.

[0030] Example 1

[0031] A retractable car jump starter includes a car jump starter 1, an n-shaped frame 2, a housing 3, a clamping mechanism 4, and a power-on mechanism 5. (See attached image.) Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, an n-shaped frame 2 is installed at the top center of the car emergency jump starter 1 by welding. A housing 3 is fixed between the lower part of the outer rear side of the n-shaped frame 2 and the rear side of the car emergency jump starter 1. A clamping mechanism 4 is installed on the upper part of the n-shaped frame 2. The operator can remove the clamping mechanism 4 and clamp it on the positive and negative terminals of the car battery. A power-conducting mechanism 5 is installed inside the n-shaped frame 2. The power-conducting mechanism 5 is connected to the clamping mechanism 4. When the car emergency jump starter 1 is started, the power-conducting mechanism 5 can energize the clamping mechanism 4.

[0032] The clamping mechanism 4 includes an L-shaped housing 42, a clamping frame 43, an arc-shaped conductive rod 44, and a first spring 45. Please refer to 1. Figure 2 , Figure 3 and Figure 6 As shown, slots 41 are opened on the upper part of the front and rear sides of the n-shaped frame 2. An L-shaped shell 42 is slidably placed in the slots 41. Rubber sleeves are fixed to the lower part of the outer side of the L-shaped shell 42 on both sides. The L-shaped shell 42 is connected to the power supply mechanism 5. A clamping frame 43 is rotatably connected to the inner top of the L-shaped shell 42. The clamping frame 43 is used for clamping. A first spring 45 is connected between the lower part of the outer side of the clamping frame 43 on both the front and rear sides and the inner side of the L-shaped shell 42 on the same side. An arc-shaped conductive rod 44 is installed on the lower part of the outer side of the clamping frame 43 on both the front and rear sides by welding. When the arc-shaped conductive rod 44 swings upward and contacts the power supply mechanism 5, the arc-shaped conductive rod 44 can introduce current into the clamping frame 43.

[0033] The energizing mechanism 5 includes a wire 51, a rotating shaft 52, a winding reel 53, a spiral spring 54, and an iron plate 55. Please refer to 1. Figure 2 , Figure 3 and Figure 6As shown, a rotating shaft 52 is symmetrically connected between the left and right sides of the n-shaped frame 2. A winding wheel 53 is installed in the middle of the rotating shaft 52 by welding. An electric wire 51 is wound on the winding wheel 53. One end of the electric wire 51 passes through the n-shaped frame 2 and is connected to the car emergency jump starter 1. The other end of the electric wire 51 passes through the n-shaped frame 2 and is fixed to an iron plate 55. When the arc-shaped conductive rod 44 contacts the iron plate 55, the iron plate 55 can conduct current into the arc-shaped conductive rod 44. The iron plate 55 is fixedly connected to the L-shaped shell 42 on the same side. The middle parts of the left and right sides of the winding wheel 53 are respectively connected to the left and right sides of the n-shaped frame 2 by spiral springs 54. The spiral springs 54 are sleeved on the rotating shaft 52.

[0034] First, the operator holds the N-shaped frame 2 and moves the car jump starter 1. When the jump starter 1 is next to the car, it is lowered, the N-shaped frame 2 is released, and the clamping mechanism 4 is pulled outward to disengage from the N-shaped frame 2. Then, the operator holds the clamping mechanism 4 and moves it. The movement of the clamping mechanism 4 moves the energizing mechanism 5, thus clamping the clamping mechanism 4 onto the positive and negative terminals of the car battery. The operator then releases the clamping mechanism 4, which stops driving the energizing mechanism 5, and starts the car jump starter 1, which then powers the car battery. The current flows into the energizing mechanism 5, which in turn inputs the current into the clamping mechanism 4. The clamping mechanism 4 then inputs the current into the car battery. When the car battery is fully charged and ready for normal use, the emergency jump starter 1 is turned off. The emergency jump starter 1 stops inputting current into the energizing mechanism 5, which in turn stops inputting current into the clamping mechanism 4. The clamping mechanism 4 then stops inputting current into the car battery. Pressing the clamping mechanism 4 disconnects it from the positive and negative terminals of the car battery. The clamping mechanism 4 is then placed back onto the n-shaped frame 2 for storage, and the energizing mechanism 5 is reset.

[0035] When the car emergency jump starter 1 is placed next to the car, pull the L-shaped housing 42 outward. Since rubber sleeves are fixed to the lower outer sides of both sides of the L-shaped housing 42, the friction with the hand is increased, allowing the operator to grip the L-shaped housing 42 more firmly. When the L-shaped housing 42 moves outward and disengages from the slot 41, holding the L-shaped housing 42 pulls the clamping frame 43 downward, compressing the first spring 45. The downward swing of the clamping frame 43 causes the arc-shaped conductive rod 44 to swing upward, contacting the energizing mechanism 5. Stop pulling the clamping frame 43 downwards, and the L-shaped shell 42 will move. The movement of the L-shaped shell 42 will move the energizing mechanism 5, which in turn will move the clamping frame 43. When the clamping frames 43 on both sides contact the positive and negative terminals of the car battery, release the clamping frame 43. Due to the action of the first spring 45, the clamping frame 43 will swing upwards a certain distance and cooperate with the L-shaped shell 42 to clamp onto the positive and negative terminals of the car battery. At this time, the arc-shaped conductive rod 44 is still in contact with the energizing mechanism 5, thus activating the car emergency jump starter 1. The emergency jump starter 1 inputs current into the energizing mechanism 5, which in turn inputs current into the arc-shaped conductive rod 44. The current in the arc-shaped conductive rod 44 then inputs current into the clamping frame 43, which in turn inputs current into the car battery for charging. When the car battery is fully charged, the emergency jump starter 1 is turned off. The emergency jump starter 1 stops inputting current into the energizing mechanism 5, and the energizing mechanism 5 stops inputting current into the arc-shaped conductive rod 44. Consequently, the clamping frame 43 also stops inputting current into the car battery. Therefore, the clamping frame 43 can be pulled to... The downward swing disengages the L-shaped housing 42 from the positive and negative terminals of the car battery. Moving the L-shaped housing 42 then moves the clamping frame 43 away from the battery's terminals, releasing the clamping frame 43. Due to the action of the first spring 45, the clamping frame 43 swings upward to reset, causing the arc-shaped conductive rod 44 to swing downward to reset. The arc-shaped conductive rod 44, swinging downward to reset, disengages from the energizing mechanism 5. This allows the L-shaped housing 42 to move back into the slot 41 and reset. The L-shaped housing 42 also moves the clamping frame 43 to reset, and the reset of the L-shaped housing 42 also resets the energizing mechanism 5. This design facilitates the use of the car power supply and also makes storage convenient.

[0036] When the operator moves the L-shaped housing 42, causing the clamping frame 43 to move, the movement of the L-shaped housing 42 also moves the iron plate 55. The movement of the iron plate 55 moves the wire 51, which in turn causes the winding wheel 53 to rotate outward, compressing the spiral spring 54. The operator then pulls the clamping frame 43 downward a certain distance, causing the clamping frame 43 to move the arc-shaped conductive rod 44 upward to contact the iron plate 55. When the clamping frame 43 moves to the vicinity of the positive and negative terminals of the car battery, it is released and contacts the positive and negative terminals of the car battery. At this point, the L-shaped housing 42 stops moving the iron plate 55, and the iron plate 55 stops moving the wire 51. The car emergency jump starter 1 is activated, and the car emergency jump starter 1 inputs current into the wire 51. The current in the wire 51 is input into the iron plate 55, and the current in the iron plate 55 is input into the arc-shaped conductive rod 44. Inside the shaped conductive rod 44, current is input into the car battery for charging via the clamping frame 43. When the car battery is fully charged, the car emergency jump starter 1 is turned off, and the car emergency jump starter stops inputting current into the wire 51. The wire 51 stops inputting current into the shaped conductive rod 44 via the iron plate 55, and the clamping frame 43 also stops inputting current into the car battery. Then, the clamping frame 43 is removed from the positive and negative terminals of the car battery, and the clamping frame 43 is released and reset. The clamping frame 43 also drives the shaped conductive rod 44 to reset. The shaped conductive rod 44 is reset and disengaged from the iron plate 55. Then, the L-shaped shell 42 is inserted back into the slot 41. The L-shaped shell 42 resets and drives the iron plate 55 to reset. The reset of the iron plate 55 causes the wire 51 to loosen. Due to the action of the spiral spring 54, the winding wheel 53 rotates inward to rewind the wire 51 back to its original position.

[0037] Example 2

[0038] Based on Embodiment 1, a drive mechanism 6 is also included. The drive mechanism 6 includes a swing plate 61, a rotating rod 62, an arc-shaped trigger rod 63, a first rack 64, a first gear 65, and a second spring 66. Please refer to [link to previous document]. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a first gear 65 is connected between the upper outer sides of the left and right sides inside the clamping frame 43. A first rack 64 is slidably connected to the top center of the L-shaped shell 42. The first rack 64 meshes with the first gear 65. When the first rack 64 moves inward, it can drive the first gear 65 to rotate inward. The outer surface of the first rack 64 on both the front and rear sides is connected to the inner side of the L-shaped shell 42 on both the front and rear sides, respectively, with a second spring 66. The lower part of the outer side of the first rack 64 on both the front and rear sides is installed with an arc-shaped trigger rod 63 by welding. Rotating rods 62 are rotatably connected to the lower part of the left and right sides inside the L-shaped shell 42. A swing plate 61 is fixedly fitted between the two rotating rods 62. The lower part of the swing plate 61 penetrates the L-shaped shell 42, and the top of the swing plate 61 contacts the bottom end of the arc-shaped trigger rod 63. When the operator pulls the swing plate 61 to rotate inward, the swing plate 61 can drive the arc-shaped trigger rod 63 to move inward.

[0039] It also includes a limiting mechanism 7, which comprises an L-shaped limiting plate 71, a connecting rod 72, a second rack 73, a second gear 74, an L-shaped rack 75, a movable plate 76, a guide rod 77, and a third spring 78. Please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, L-shaped limiting plates 71 are embedded and slidably connected to the upper parts of the front and rear sides of the n-shaped frame 2. The top of the L-shaped limiting plate 71 passes through the n-shaped frame 2 and is located in the slot 41. The L-shaped limiting plate 71 can limit the L-shaped shell 42. Two connecting rods 72 are installed between the lower part of the rear side of the front L-shaped limiting plate 71 and the lower part of the front side of the rear L-shaped limiting plate 71 by welding. The connecting rods 72 pass through the n-shaped frame 2. A second rack 73 is installed in the middle of the rear side of the rear L-shaped limiting plate 71 by welding. The second rack 73 is located inside the shell 3. A second gear 74 is rotatably connected between the upper parts of the left and right sides of the shell 3. The second gear 74 meshes with the second rack 73. When the second gear 74 reverses, the second gear 74... The second rack 73 can be driven to move downward. An L-shaped rack 75 is slidably connected to the middle of the rear side of the bottom of the housing 3. The L-shaped rack 75 meshes with the second gear 74. When the second gear 74 moves downward, the L-shaped rack 75 can drive the second gear 74 to reverse. Guide rods 77 are symmetrically embedded and slidably connected on the front and rear sides of the bottom of the car emergency jump starter 1. The bottom ends of the four guide rods 77 are connected by welding to install a movable plate 76. The middle of the rear side of the movable plate 76 is connected to the front end of the L-shaped rack 75 by welding. The top front and rear sides of the movable plate 76 are symmetrically connected to a third spring 78. The third spring 78 is sleeved on the guide rod 77. The tail end of the third spring 78 is fixedly connected to the bottom of the car emergency jump starter 1.

[0040] When the clamping frame 43 moves to the vicinity of the positive and negative terminals of the vehicle's power supply, it pulls the swing plate 61, causing its upper side to rotate inward. This inward rotation of the swing plate 61 moves the arc-shaped trigger rod 63 inward, which in turn moves the first rack 64 inward, stretching the second spring 66. The inward movement of the first rack 64 then rotates the first gear 65 inward, causing the clamping frame 43 to swing downward. When the swing plate 61 reaches its maximum inward rotation, it stops moving the first gear 66 via the arc-shaped trigger rod 63. When rack 64 moves inward, the first rack 64 stops, causing the clamping frame 43 to swing downward via the first gear 65. This allows the L-shaped shell 42 to move, bringing the clamping frame 43 into contact with the positive and negative terminals of the car battery. When the swing plate 61 is released, the first rack 64 moves inward due to the action of the second spring 66, causing the first gear 65 to rotate outward. The outward rotation of the first gear 65 causes the clamping frame 43 to swing upward a certain distance. The clamping frame 43 then clamps onto the positive and negative terminals of the car battery through its cooperation with the L-shaped shell 42, thus starting the charging of the car battery. Once the car battery is fully charged, pulling the clamping frame 43 downwards disengages it from the positive and negative terminals of the car battery. Simultaneously, moving the L-shaped housing 42 moves the clamping frame 43 away from the battery terminals. Due to the action of the second spring 66, the first rack 64 moves outwards to reset, causing the first gear 65 to rotate outwards to reset. The reset of the first gear 65 causes the clamping frame 43 to swing upwards to reset. At the same time, the outward movement of the first rack 64 causes the arc-shaped trigger rod 63 to move outwards to reset, which in turn causes the swing plate 61 to rotate outwards to reset. This eliminates the need for the operator to manually pull the clamping frame 43 downwards a certain distance, making the process convenient and quick.

[0041] When the operator places the car emergency jump starter 1 on the ground, the car emergency jump starter, via the third spring 78, causes the movable plate 76 to contact the ground. The ground limits the movement of the movable plate 76, stopping its downward movement. The movable plate 76 also stops the downward movement of the L-shaped rack 75. As the car emergency jump starter 1 continues to move downward, the third spring 78 is compressed. Simultaneously, the car emergency jump starter 1 also causes the housing 3 to move downward. The downward movement of the housing 3 causes the second gear 74 to move downward. The L-shaped rack 75 then reverses the downward movement of the second gear 74, causing the second rack 73 to move downward. The downward movement of the second rack 73 causes the rear L-shaped limiting plate 71 to move downward. The downward movement of the rear L-shaped limiting plate 71 causes the front L-shaped limiting plate 71 to move downward. The downward movement of the front and rear L-shaped limiting plates 71 does not limit the movement of the L-shaped housing 42. Pull the L-shaped housing 42 outward to disengage it from the slot 41. After the car battery is fully charged, insert the L-shaped housing 42 back into the slot 41. Then, hold the n-shaped frame 2 and lift the car emergency jump starter 1 from the ground. The car emergency jump starter 1 moves upward, which drives the movable plate 76 to move upward and disengage it from the ground via the third spring 78. Due to the action of the third spring 78, the movable plate 76 moves downward to reset, which drives the L-shaped rack 75 to move downward to reset. The L-shaped rack 75 moves downward to reset, which drives the second gear 74 to rotate forward to reset. The second gear 74 rotates forward to reset, which drives the second rack 73 to move upward to reset. The second rack 73 moves upward to reset, which drives the rear L-shaped limiting plate 71 to move upward to reset. The rear L-shaped limiting plate 71 moves upward to reset, which drives the front L-shaped limiting plate 71 to move upward to reset via the connecting rod 72. The front and rear L-shaped limiting plates 71 move upward to reset, continuing to limit the L-shaped housing 42. In this way, when the car emergency jump starter 1 is moved, the L-shaped housing 42 can be prevented from detaching from the slot 41 and falling off, thus affecting its movement.

[0042] Example 3

[0043] Based on Embodiments 1 and 2, it also includes a sliding plate 8 and a ceramic ring 9. Please refer to [link / reference]. Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, a sliding plate 8 is symmetrically embedded in the middle of the top of the n-shaped frame 2. A ceramic ring 9 is fixedly connected in the middle of the sliding plate 8. The wire 51 passes through the ceramic ring 9, and the ceramic ring 9 can guide the wire 51.

[0044] It also includes a contact plate 10, a fourth spring 11, and a latch 12. Please refer to [link / reference]. Figures 3-5As shown, a limiting groove 13 is opened in the middle of the bottom of the swing plate 61. A contact plate 10 is slidably connected to the bottom of the L-shaped shell 42. The contact plate 10 contacts the slot 41. A fourth spring 11 is symmetrically connected between the top of the contact plate 10 and the inner side of the L-shaped shell 42. A locking rod 12 is installed in the middle of the inner side of the top of the contact plate 10 by welding. The top of the locking rod 12 passes through the L-shaped shell 42 and is located in the limiting groove 13. The locking rod 12 can limit the swing plate 61.

[0045] When the L-shaped shell 42 moves the wire 51 via the iron plate 55, the wire 51 slides on the ceramic ring 9, which guides the wire 51. Simultaneously, the wire 51 moves the ceramic ring 9 left and right, which in turn moves the sliding plate 8 left and right. When the winding wheel 53 rotates inward to rewind and reset the wire 51, the rewinding of the wire 51 again moves the ceramic ring 9 left and right, which in turn moves the sliding plate 8 left and right again. The ceramic ring 9 continues to guide the wire 51. When the wire 51 stops being rewound, it stops moving the ceramic ring 9 left and right, and the ceramic ring 9 stops moving the sliding plate 8 left and right. This allows the wire 51 to be wound and unwound more effectively.

[0046] Initially, the fourth spring 11 is in a compressed state. When the operator pulls the L-shaped shell 42 outward, the outward movement of the L-shaped shell 42 also drives the locking rod 12 outward. The outward movement of the locking rod 12 drives the contact plate 10 outward. When the L-shaped shell 42 disengages from the locking groove 41, it means that the contact plate 10 has moved outward and disengaged from the locking groove 41. Due to the action of the fourth spring 11, the contact plate 10 moves downward, driving the locking rod 12 to move downward and disengage from the limiting groove 13. The disengagement of the locking rod 12 from the limiting groove 13 does not limit the swing plate 61, and the swing plate 61 can be pulled to rotate inward. When the operator inserts the L-shaped shell 42 back into the slot 41, the L-shaped shell 42, through the locking rod 12, causes the contact plate 10 to contact the slot 41. The slot 41 causes the contact plate 10 to move upward, compressing the fourth spring 11. The upward movement of the contact plate 10 causes the locking rod 12 to move upward and reset. The locking rod 12 then resets and inserts into the limiting slot 13, continuing to limit the swing plate 61. In this way, without needing to pull the swing plate 61 inward, it avoids accidental inward rotation of the swing plate 61, which could cause the clamping frame 43 to swing downward.
