Description

Technical Field

[0001] The present invention relates to the technical field of charging guns, and in particular to a more stable charging gun. Background Art

[0002] The charging gun is an important component in the charging pile that directly connects to the electric vehicle. The common charging gun we see is generally a whole unit, which is directly inserted into the charging port of the electric vehicle when in use. However, since the power cord is always connected between the charging gun and the main charging station, it is easy for people to accidentally pull the charging gun and cause poor contact, which brings trouble to the charging operation. Summary of the Invention

[0003] In summary, in order to overcome the deficiencies of the prior art, the present invention provides a more stable charging gun that is not easily loosened or fallen off when the power cord is pulled.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a more stable charging gun, a more stable charging gun, comprising a charging gun body, a plug at one end of the charging gun body and a power cord at the other end, and a fixed suction cup, a protruding end of the fixed suction cup is provided with a connecting mechanism, the connecting mechanism is connected to the power cord, the fixed suction cup is provided with an exhaust port, the exhaust port is provided with a valve plug adapted thereto, the valve plug is located on the side of the connecting mechanism facing the charging gun body, the valve plug is linked to the power cord, the valve plug is provided with a first spring, a linkage rod is provided at the end of the valve plug facing away from the exhaust port, a push plate with a diameter larger than the exhaust port is provided between the valve plug and the linkage rod, the first spring is sleeved outside the linkage rod, the fixed suction cup is provided with a connecting frame at the position of the exhaust port, the connecting frame is provided with a connecting plate, the linkage rod is arranged through the connecting plate, and the first spring is located between the connecting plate and the fixed suction cup.

[0005] With this arrangement, when the electric vehicle is out of power, you can first insert the plug of the charging gun body into the charging position on the electric vehicle, and then press the fixed suction cup on the power cord on the vehicle shell near the charging position to adsorb it. The fixed suction cup will be compressed by negative pressure, and a part of the power cord will be fixed to that position. When people accidentally touch or trip over the power cord, the movement of the power cord will be interrupted when it reaches the position of the connecting mechanism, and the connecting mechanism will be transmitted to the fixed suction cup after being subjected to the force. The fixed suction cup is pressed by negative pressure and is not easy to move. In this way, the force transmitted by accidentally touching the power cord will be dissipated and will not reach the charging gun body to cause it to loosen or fall off. After charging is completed, pull out the charging gun body, and then the charging gun body will pull the power cord. When the power cord on that side is pulled, it will drive the valve plug linked to it and pull it out of the exhaust port. After the valve plug is pulled out, air will be exhausted. The air flow flows into the fixed suction cup to balance the pressure. At this time, the fixed suction cup can be pulled down freely and will no longer be adsorbed on the vehicle shell. Since the valve plug is located on the side of the connecting mechanism facing the charging gun body, the valve plug will be pulled out only when the charging gun body is pulled out, and it will not be affected when the power cord at the other end is pulled. When the power cord on the charger body side is not pulled out of the angle, the valve plug will be pressed by the first spring and pushed into the exhaust port, without the need to plug it manually. At the same time, the first spring can prevent the valve plug from falling out. The two ends of the spring are respectively pressed on the connecting plate and the push plate. The position of the connecting plate is fixed, so the spring will push the push plate toward the exhaust port. The diameter of the push plate is larger than the exhaust port, so it will not be pushed into the exhaust port, and the valve plug will not be pushed over. After the valve plug is provided with a linkage rod, the linkage rod penetrates the connecting plate to form a sliding internal connection with the connecting plate, sliding on the connecting plate, which is more stable, and the spring sleeve on the linkage rod will not bounce off.

[0006] Furthermore, the connecting frame is barrel-shaped, the fixed suction cup is provided with a connecting ring arranged around the exhaust port, the connecting frame is threadedly connected to the connecting ring, and the connecting plate is provided with a plurality of air holes.

[0007] With this arrangement, the barrel-shaped connecting frame can be directly screwed onto the connecting ring to complete the connection during installation. The connection is convenient and stable, and after the connection, the spring is completely blocked in the barrel-shaped connecting frame. When the valve plug is pulled out, air will flow in from the air vent without being blocked.

[0008] Furthermore, a linkage rope is provided at one end of the linkage rod facing away from the exhaust port, and the linkage rope loop is arranged outside the power cord.

[0009] With this arrangement, after the linkage rope is looped over the power cord, when the charging gun body is taken out and the power cord is pulled, the power cord will pull the linkage rope to pull up the valve plug, which has a simple structure.

[0010] Furthermore, the fixed suction cup is provided with a winding mechanism, one end of the linkage rope is connected to the linkage rod, and the other end is connected to the winding mechanism.

[0011] With such arrangement, the reeling mechanism can reel in the linkage rope, thereby controlling the total length of the linkage rope, thereby changing the tightness of the linkage rope loop on the power cord, and the operation is convenient.

[0012] Furthermore, the winding mechanism includes a winding rod, two winding plates are provided at one end of the fixed suction cup protrusion, the winding rod passes through the two winding plates, a polygonal head is provided at one end of the winding rod, and a polygonal groove adapted to the position of the polygonal head is provided on the winding plate corresponding to the position of the polygonal head, and a driving head fixedly connected to the other end of the winding rod is provided, and a second spring is provided between the driving head and the winding plate and is sleeved on the outside of the winding rod.

[0013] With this arrangement, when operating, you only need to press the drive head to compress the second spring. At this time, the polygonal head at the other end of the winding rod will be pushed out. At this time, you can rotate the drive head to allow the winding rod that passes through the two winding plates to rotate freely. After the winding rope is tied to the winding rod, it will be rolled up when the winding rod rotates, thereby reducing its exposed length. When the linkage rope is adjusted to the required length, release it and the restoring force of the second spring will push the drive head back to its original position. The polygonal head at the other end will be pressed back into the polygonal groove. At this time, the winding rod can no longer rotate. Using a polygonal head to limit rotation is easier to process, and the number of its edges can be adjusted according to needs, and it can stop at multiple different angles.

[0014] Furthermore, the connecting mechanism includes an arc clamp and an elastic member, and there are two arc clamps, which are arranged opposite to each other. Two hinge plates are provided at one end of the fixed suction cup protrusion, and the bottoms of the two arc clamps are hinged to each other. One of the arc clamps is fixedly connected to the hinge plate. The arc radius of the arc clamp is adapted to the power cord. When the two arc clamps are fitted with the power cord, there is a gap between the tops of the two. The elastic member applies a force toward each other on the two arc clamps, and a rubber layer is provided on the side of the arc clamp facing the power cord.

[0015] With such a configuration, the elastic member can prompt the two arc-shaped clamps to clamp the power cord. After clamping, the rubber layer inside the arc-shaped clamps will fit the power cord to prevent it from sliding after clamping. When the position of the fixed suction cup needs to be changed, the two arc-shaped clamps can be stretched open to compress the elastic member so that the rubber layer will be disconnected from the power cord. At this time, the two arc-shaped clamps can be pulled freely to change the position of the fixed suction cup. When the fixed suction cup moves to the position required by the user, the user releases the hand, and the elastic member will prompt the two arc-shaped clamps to clamp the power cord again, so that the fixed suction cup stays in the current position, and one of the arc-shaped clamps is fixedly connected to the hinged plate. The power cord clamped by the arc-shaped clamp will not swing left and right, causing the valve plug to be pulled out when it swings. The fixed suction cup can be placed below the charging position to keep the power cord vertical to prevent the valve plug from being pulled out prematurely due to gravity swing.

[0016] Furthermore, the tops of the two arc-shaped clamps are provided with a plurality of staggered plates arranged toward each other, the top surfaces of the staggered plates are provided with vertical plates, the tops of the arc-shaped clamps are provided with pressing plates inserted on the vertical plates and fixedly connected to the vertical plates, the width of the pressing plates is adapted to the width of the arc-shaped clamps, the elastic member is located between the two pressing plates, and there is a gap between the two pressing plates.

[0017] With this arrangement, after the two arc-shaped clamps are clamped together, the several staggered plates on the top will stagger and pass through the two sides of the two arc-shaped clamps. After the installation is completed, the pressing plate is inserted on the vertical plate, and the elastic member is located between the two. In this way, the elastic member will stretch the pressing plates on both sides, and the two arc-shaped clamps will naturally be pushed toward each other to clamp the power cord. When the position of the fixed suction cup needs to be changed, just grab the two pressing plates and clamp them. This will compress the elastic member between the two. During the clamping process, the two arc-shaped clamps will be stretched apart. After reaching the designated position, let go and the two pressing plates will be pushed back by the elastic member. The operation is simple.

[0018] Furthermore, the elastic member is a spring, and there are several of the elastic members. A spring groove is provided on the side of the pressing plate facing the other pressing plate. The elastic member is located in the spring groove. The axial cross-section of the spring groove is a triangle raised away from the arc clamp. The width of the spring groove is adapted to the elastic member, and a ball with a diameter smaller than the width of the spring groove is provided at each end of the elastic member.

[0019] With this arrangement, several springs can be placed in the spring slots, and the springs will apply thrust to both sides, causing the two arc-shaped clamps to clamp. The number of springs can be changed to change the clamping force. When the two arc-shaped clamps need to be opened, the relative angle of the two pressing plates will change. At this time, the triangular spring slot provides space for the spring to move, so that it remains straight when the angle of the two pressing plates changes. The balls on both sides can also prevent the end face angle of the spring from changing, thereby causing it to bend. The spring is more stable, and the spring is located in the spring slot and cannot pop out from the initial spacing between the two pressing plates. The spacing between the two pressing plates will only shrink and not increase, so the spring will not pop out.

[0020] Furthermore, the hinge plate is provided with a connecting shaft, the cross-section of the connecting shaft is square, the connecting shaft passes through the hinge plate and the arc clamp, the position of the arc clamp that is not fixedly connected to the hinge plate and is passed through by the connecting shaft is provided with a circular hole, and the position of the connecting shaft corresponding to the circular hole is provided with a cylindrical sleeve that is sleeved on the outside of the connecting shaft.

[0021] With this arrangement, the square connecting shaft will be fixed in relative rotation with the hinged plate and the arc-shaped clamp after being inserted into the shaft, and the two will be unable to rotate. A round cylindrical sleeve is sleeved outside the square connecting shaft, and the cylindrical sleeve is located in the round hole on one of the arc-shaped clamps. The arc-shaped clamp can swing around the cylindrical sleeve to clamp or release the power cord. The structure is simple.

[0022] Furthermore, the arc-shaped clamp is provided with several circular grooves on the side facing the power cord, and a spring plunger is provided in the circular groove. The end of the arc-shaped clamp facing away from the power cord is provided with a thickened boss corresponding to the position of the spring plunger, and the elastic force of the spring plunger is smaller than that of the elastic member.

[0023] With this arrangement, when adjustment is needed, the spring plunger will pop out, and the contact position between the arc clamp and the power cord will be changed to the steel ball part of the spring plunger. At this time, the sliding adjustment will be smoother. After moving to the appropriate position and clamping, the rubber layer will contact the power cord again, and the spring plunger will be pressed back into the circular groove, which will not affect the fixing situation. After setting the thickened boss, a circular groove for placing the spring plunger can be processed at the position of the thickened boss. The depth of the circular groove can be set larger, and the overall thickness of the arc clamp does not need to be thickened, which saves more materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] This specific embodiment is merely an explanation of this embodiment and is not a limitation of this embodiment. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of this embodiment, they are protected by patent law.

[0031] Referring to the accompanying drawings, the present invention provides the following technical solutions: a more stable charging gun, a more stable charging gun, comprising a charging gun body 1, wherein the charging gun body 1 is provided with a plug 101 at one end and a power cord 102 at the other end, and further comprising a fixed suction cup 2, wherein a protruding end of the fixed suction cup 2 is provided with a connecting mechanism 201, wherein the connecting mechanism 201 is connected to the power cord 102, and the fixed suction cup 2 is provided with an exhaust port 202, wherein the exhaust port 202 is provided with a valve plug 203 adapted thereto, wherein the valve plug 203 is located on the side of the connecting mechanism 201 facing the charging gun body 1, and the valve plug 203 is linked to the power cord 102. The valve plug 203 is provided with a first spring 2031, and a linkage rod 2032 is provided at the end of the valve plug 203 facing away from the exhaust port 202. A push plate 2033 with a diameter larger than that of the exhaust port 202 is provided between the valve plug 203 and the linkage rod 2032. The first spring 2031 is sleeved on the outside of the linkage rod 2032, and the fixed suction cup 2 is located at the position of the exhaust port 202 and is provided with a connecting frame 204. The connecting frame 204 is provided with a connecting plate 2041, and the linkage rod 2032 is arranged through the connecting plate 2041. The first spring 2031 is located between the connecting plate 2041 and the fixed suction cup 2.

[0032] With this arrangement, when the electric vehicle is out of power, the plug 101 of the charging gun body 1 can be inserted into the charging position on the electric vehicle first, and then the fixed suction cup 2 on the power cord 102 can be pressed against the vehicle shell near the charging position to be adsorbed. The fixed suction cup 2 will be pressed tightly by negative pressure, and a part of the power cord 102 will be fixed to the position. When people accidentally touch or trip over the power cord 102, the activity of the power cord 102 will be interrupted when it reaches the position of the connecting mechanism 201, and the connecting mechanism 201 will be transmitted to the position when it is subjected to the force. On the fixed suction cup 2, the fixed suction cup 2 is pressed by negative pressure and is not easy to move. In this way, the force transmitted by accidentally touching the power cord 102 will be dissipated and will not reach the charging gun body 1 to cause it to loosen or fall off. After charging is completed, the charging gun body 1 is pulled out, and then the charging gun body 1 will pull the power cord 102. When the power cord 102 on this side is pulled, it will drive the valve plug 203 linked to it and pull it out of the exhaust port 202. After the valve plug 203 is pulled out, air will flow into the fixed suction cup 2 to balance the pressure. At this time, the fixed suction cup 2 can be pulled freely. The valve plug 203 is located on the side of the connecting mechanism 201 facing the charging gun body 1, so the valve plug 203 will be pulled out only when the charging gun body 1 is pulled out, and it will not be affected when the power cord 102 on the other end is pulled. When the power cord 102 on the charger body side is not pulled out of the angle, the valve plug 203 will be pressed by the first spring 2031 and pushed into the exhaust port 202, without manual plugging. At the same time, the first spring 2031 can prevent the valve plug 203 from falling out, and the two ends of the spring are pressed on the connecting mechanism 201. The position of the plate 2041 and the push plate 2033, the position of the connecting plate 2041 is fixed, so the spring will push the push plate 2033 toward the exhaust port 202, and the push plate 2033 has a diameter larger than the exhaust port 202, and will not be pushed into the exhaust port 202, and the valve plug 203 will not be pushed too far. After the valve plug 203 is provided with a linkage rod 2032, the linkage rod 2032 penetrates the connecting plate 2041 and will form a sliding internal connection with the connecting plate 2041, sliding on the connecting plate 2041, which is more stable, and the spring sleeve on the linkage rod 2032 will not bounce off.

[0033] In this embodiment, the connecting frame 204 is preferably barrel-shaped, the fixed suction cup 2 is provided with a connecting ring 205 arranged around the exhaust port 202, the connecting frame 204 is threadedly connected to the connecting ring 205, and the connecting plate 2041 is provided with a plurality of air holes 20411.

[0034] With this arrangement, the barrel-shaped connecting frame 204 can be directly screwed onto the connecting ring 205 during installation to complete the connection. The connection is convenient and stable, and after the connection, the spring is completely blocked in the barrel-shaped connecting frame 204. When the valve plug 203 is pulled out, air will flow in from the position of the air vent 20411 without being blocked.

[0035] Preferably, in this embodiment, a linkage rope 206 is provided at one end of the linkage rod 2032 facing away from the exhaust port 202 , and the linkage rope 206 is sleeved outside the power cord 102 .

[0036] With this arrangement, after the linkage rope 206 is sleeved on the power cord 102 , when the charging gun body 1 is taken out and the power cord 102 is pulled, the power cord 102 will pull the linkage rope 206 to pull up the valve plug 203 , which has a simple structure.

[0037] In this embodiment, the fixed suction cup 2 is preferably provided with a reeling mechanism 207 , and one end of the linkage rope 206 is connected to the linkage rod 2032 , and the other end is connected to the reeling mechanism 207 .

[0038] With this arrangement, the reeling mechanism 207 can reel the linkage rope 206 , thereby controlling the total length of the linkage rope 206 , thereby changing the tightness of the linkage rope 206 on the power cord 102 , which is easy to operate.

[0039] Preferably, in this embodiment, the winding mechanism 207 includes a winding rod 2071, and two winding plates 208 are provided at one end of the protrusion of the fixed suction cup 2. The winding rod 2071 is arranged to pass through the two winding plates 208. A polygonal head 2071 is provided at one end of the winding rod 2071, and a polygonal groove 2081 is provided to match the position of the polygonal head 20711 on the winding plate 208. The other end of the winding rod 2071 is provided with a driving head 2072 fixedly connected to it, and a second spring 2073 is provided between the driving head 2072 and the winding plate 208 and is sleeved on the outside of the winding rod 2071.

[0040] With this arrangement, when operating, one only needs to press the drive head 2072 to compress the second spring 2073. At this time, the polygonal head 20711 at the other end of the winding rod 2071 will be pushed out. At this time, the drive head 2072 can be rotated to allow the winding rod 2071 that passes through the two winding plates 208 to rotate freely. After the winding rope is tied to the winding rod 2071, the winding rod 2071 will be rolled up when it rotates, thereby reducing its exposed length. When the linkage rope 206 is adjusted to the required length, release it, and the restoring force of the second spring 2073 will push the drive head 2072 to return to its original position, and the polygonal head 20711 at the other end will be pressed back into the polygonal groove 2081. At this time, the winding rod 2071 can no longer rotate. Using the polygonal head 20711 to limit rotation is easier to process, and the number of its edges can be adjusted according to needs, and it can stop at multiple different angles.

[0041] In this embodiment, the connecting mechanism 201 preferably includes an arc-shaped clamp 2011 and an elastic member 2012. Two arc-shaped clamps 2011 are provided, and the two arc-shaped clamps 2011 are arranged opposite to each other. Two hinge plates 209 are provided at one end of the protrusion of the fixed suction cup 2. The bottoms of the two arc-shaped clamps 2011 are hinged to each other, and one of the arc-shaped clamps 2011 is fixedly connected to the hinge plate 209. The arc radius of the arc-shaped clamp 2011 is adapted to the power cord 102. When the two arc-shaped clamps 2011 are fitted with the power cord 102, there is a gap between the tops of the two. The elastic member 2012 applies a force toward each other on the two arc-shaped clamps 2011, and a rubber layer is provided on the side of the arc-shaped clamp 2011 facing the power cord 102.

[0042] With this arrangement, the elastic member 2012 can prompt the two arc-shaped clamps 2011 to clamp the power cord 102. After clamping, the rubber layer inside the arc-shaped clamp 2011 will fit the power cord 102 to prevent it from sliding after clamping. When the position of the fixed suction cup 2 needs to be changed, the two arc-shaped clamps 2011 can be stretched open to compress the elastic member 2012, so that the rubber layer will be disconnected from the power cord 102. At this time, the two arc-shaped clamps 2011 can be pulled freely to change the position of the fixed suction cup 2. When the fixed suction cup 2 is moved to the position where the fixed suction cup 2 is used, the rubber layer can be disengaged. When the user releases his hand when the power cord 102 is in the desired position, the elastic member 2012 will again prompt the two arc-shaped clamps 2011 to clamp the power cord 102, so that the fixed suction cup 2 stays in the current position, and one of the arc-shaped clamps 2011 is fixedly connected to the hinged plate 209. The power cord 102 clamped by the arc-shaped clamp 2011 will not swing left and right, thereby preventing the valve plug 203 from being pulled out when it swings. The fixed suction cup 2 can be placed below the charging position to keep the power cord vertical and prevent it from swinging due to gravity and pulling out the valve plug 203 in advance.

[0043] Preferably, in this embodiment, the tops of the two arc-shaped clamps 2011 are provided with a plurality of staggered plates 20114 which are staggered and arranged toward each other, and the top surfaces of the staggered plates 20114 are provided with vertical plates 20115. The tops of the arc-shaped clamps 2011 are provided with pressing plates 2013 which are inserted into and fixedly connected to the vertical plates 20115, and the width of the pressing plates 2013 is adapted to the width of the arc-shaped clamps 2011. The elastic member 2012 is located between the two pressing plates 2013, and there is a gap between the two pressing plates 2013. A groove can be provided at the bottom of the pressing plate 2013 for insertion, and the pressing plate 2013 can be connected to the vertical plates 20115 in various ways such as gluing and bolting.

[0044] With such arrangement, after the two arc-shaped clamps 2011 are clamped together, the several staggered plates 20114 on the top will cross over to the two sides of the two arc-shaped clamps 2011. After the installation is completed, the pressing plate 2013 is inserted on the vertical plate 20115, and the elastic member 2012 is located between the two. In this way, the elastic member 2012 will stretch the pressing plates 2013 on both sides, and the two arc-shaped clamps 2011 will naturally be pushed toward each other to clamp the power cord 102. When the position of the fixed suction cup 2 needs to be changed, just grab the two pressing plates 2013 and clamp them, which will compress the elastic member 2012 between the two. During the clamping process, the two arc-shaped clamps 2011 will be stretched apart. After reaching the specified position, let go of the two pressing plates 2013 and they will be pushed back by the elastic member 2012. The operation is simple.

[0045] In this embodiment, the elastic member 2012 is preferably a spring, and a plurality of the elastic members 2012 are provided. A spring groove 20131 is provided on the side of the pressing plate 2013 facing the other pressing plate 2013. The elastic member 2012 is located in the spring groove 20131. The axial cross-section of the spring groove 20131 is a triangle rising away from the arc clamp 2011. The width of the spring groove 20131 is adapted to the elastic member 2012. A ball 20121 with a diameter smaller than the width of the spring groove 20131 is provided at each end of the elastic member 2012.

[0046] With such a configuration, several springs can be placed in the spring groove 20131, and the springs will apply a thrust to both sides, causing the two arc-shaped clamps 2011 to clamp. The number of springs can be changed to change the clamping force. When the two arc-shaped clamps 2011 need to be opened, the relative angle of the two pressing plates 2013 will change. At this time, the triangular spring groove 20131 provides the spring with room to move, so that it remains straight when the angle of the two pressing plates 2013 changes. The balls 20121 on both sides can also prevent the end face angle of the spring from changing, thereby causing it to bend, making the spring more stable. Moreover, the spring is located in the spring groove 20131 and cannot pop out from the initial spacing between the two pressing plates 2013. The spacing between the two pressing plates 2013 will only shrink and not increase, so the spring will not pop out.

[0047] Preferably, the hinge plate 209 is provided with a connecting shaft 2091, the cross-section of the connecting shaft 2091 is square, the connecting shaft 2091 passes through the hinge plate 209 and the arc clamp 2011, and a circular hole 20116 is provided at the position of the arc clamp 2011 that is not fixedly connected to the hinge plate 209 and is passed through by the connecting shaft 2091. The connecting shaft 2091 is provided with a cylindrical sleeve 2092 that is sleeved on the outside of the connecting shaft 2091 at a position corresponding to the circular hole 20116.

[0048] With such a configuration, the square connecting shaft 2091 is fixed in relative rotation with the hinged plate 209 and the arc-shaped clamp 2011 after being inserted therein, and cannot rotate. A circular cylindrical sleeve 2092 is sleeved on the outside of the square connecting shaft 2091, and the cylindrical sleeve 2092 is located in a circular hole 20116 on one of the arc-shaped clamps 2011. The arc-shaped clamp 2011 can swing around the cylindrical sleeve 2092, thereby clamping or loosening the power cord 102, with a simple structure.

[0049] In this embodiment, the arc clamp 2011 is preferably provided with a plurality of circular grooves 20111 on the side facing the power cord 102, a spring plunger 20112 is provided in the circular groove 20111, and a thickened boss 20113 is provided at the end of the arc clamp 2011 facing away from the power cord 102 corresponding to the position of the spring plunger 20112, and the elastic force of the spring plunger 20112 is smaller than that of the elastic member 2012.

[0050] With such a setting, when adjustment is needed, the spring plunger 20112 will pop out, and the contact position between the arc clamp 2011 and the power cord 102 will be changed to the steel ball part of the spring plunger 20112. At this time, the sliding adjustment is smoother. After moving to the appropriate position and clamping, the rubber layer will contact the power cord 102 again, and the spring plunger 20112 will be pressed back into the circular groove 20111, which will not affect the fixing situation. After the thickened boss 20113 is set, the circular groove 20111 for placing the spring plunger 20112 can be processed at the position of the thickened boss 20113. The depth of the circular groove 20111 can be set larger, and the overall thickness of the arc clamp 2011 does not need to be thickened, which saves more materials.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
