In addition, the adapter is also clamped with the track plate through the lock catch, and the clamping structure of the adapter is also a technical key point of various track type socket products.

Disclosure of Invention

In view of the above, the present utility model provides an adapter and a rail type socket having the same, so as to more conveniently mount the adapter on a rail plate of the rail type socket.

In a first aspect, the present utility model provides an adapter for a rail-type receptacle, the adapter comprising a base and a pair of locking blocks, an adjusting ring and a set of drive mechanisms disposed on the base. The base is formed with the spacing that deviates from its bottom surface and stretches out, the first window on the spacing communicates the relative both sides of spacing. One end of each locking piece is provided with a rotating shaft, and the other end of each locking piece is provided with a lock catch; the two rotating shafts are parallel to the bottom surface of the base, the pair of locking blocks are oppositely arranged on the base, and the two locking catches are opposite to the two opposite sides of the first window respectively. The adjusting ring is arranged on the top surface of the base and can move axially relative to the base. The transmission mechanism is arranged between the adjusting ring and the pair of locking blocks and is configured to transmit when the adjusting ring moves axially relative to the base so as to drive the pair of locking blocks to open and close around respective rotating shafts.

As can be seen from the above, during use of the orbital receptacle, the adjustment ring can be in a first axial position relative to the base prior to mounting the adapter to the orbital plate, and the two locking blocks can be retracted synchronously inside the first window; after the limiting frame on the base of the adapter stretches into the limiting opening of the track plate, the adjusting ring can move to the second axial position relative to the base, and the two locking blocks synchronously stretch out of two sides of the limiting frame to be clamped on inner walls of two sides of the limiting opening. In this way, the adapter can be more conveniently and reliably arranged on the track plate.

The above-described transmission mechanism may be, for example, a gear transmission mechanism, a crank-link transmission mechanism, or the like. In a preferred embodiment, the transmission mechanism may comprise a lifting member and a sliding member. Optionally, the pair of locking pieces are formed with mutually cooperating engaging portions or rolling portions around the respective rotation shafts. So that a pair of locking pieces can swing synchronously around respective rotating shafts.

A poppet is coupled to the adjustment ring for axial movement with the adjustment ring relative to the base. For example, the lifting member is formed with at least one concave ring part, and a convex ring part in rotation limit fit with the concave ring part is formed on the inner peripheral wall of the adjusting ring, so that the lifting member is in rotation limit connection with the adjusting ring. For another example, a convex part is arranged on the lifting member to be matched with a concave part on the inner wall of the adjusting ring, so that the lifting member can move along with the adjusting ring along the axial direction relative to the base. Preferably, the lifting member is further provided with a limiting rod extending towards the base, a limiting groove extending into the limiting frame is formed in the base, and the limiting rod is in sliding fit with the limiting groove so as to keep the lifting member to axially move relative to the base. Similarly, corresponding slots may be provided in the poppet member to provide a positive engagement with a stem provided on the base to maintain axial movement of the poppet member relative to the base.

The sliding piece can be provided with a limiting inclined plane in sliding fit with the lifting piece, and when the lifting piece moves axially, the sliding piece slides on the base in a direction close to or far away from the locking pieces so as to drive the pair of locking pieces to swing in an opening and closing mode. Preferably, the lifting member may further be formed with a limit table protruding toward the limit inclined surface, the limit table being provided to be slidably fitted with the limit inclined surface of the sliding member. In another alternative embodiment, the adjusting ring may be provided with a boss similar to the limiting table, without the lifting member, so as to be in sliding fit with the sliding block, and the sliding member is enabled to move along the base when the adjusting ring moves axially relative to the base.

In an alternative embodiment, the transmission mechanism further comprises: and the torsion spring is arranged between the sliding piece and the locking piece so as to drive the pair of locking pieces to open and close in the sliding process of the sliding piece.

Illustratively, the torsion spring comprises two spiral rings coaxially arranged, one ends of the two spiral rings extend outwards and then are connected with two ends of a cross rod, and the cross rod is parallel to the axis of the torsion spring; the other ends of the two spiral rings extend outwards and are respectively provided with a supporting leg. The transverse rod is in compression joint with one side of the sliding piece, which is opposite to the limiting inclined plane, and the two supporting legs are respectively arranged in corresponding one of the two locking blocks, so that when the sliding piece slides towards the direction close to the locking blocks, the two locking blocks are closed under the elastic deformation action of the torsion spring; and when the sliding piece slides in a direction away from the locking pieces, the two locking pieces are opened under the action of the elastic restoring force of the torsion spring.

In the above technical scheme, when the adjusting ring is lifted up relative to the base, the sliding piece moves towards the direction close to the pair of locking blocks, so that the torsion spring is compressed and drives the pair of locking blocks to be closed through the two supporting legs of the torsion spring, and the limit frame of the adapter base can be stretched into the track plate or the adapter can be taken down from the track plate. And when the adjusting ring moves downwards relative to the base, the sliding piece moves towards the direction away from the pair of locking blocks, so that the torsion spring is relaxed and drives the pair of locking blocks to open through two supporting legs of the torsion spring, and therefore, in the state that the limiting frame of the adapter base stretches into the track plate, the pair of locking blocks can be clamped on two sides of the inner wall of the limiting opening of the track plate.

It should be noted that, through changing the form of the torsion spring, the locking blocks can be blocked at two sides of the inner wall of the limit opening of the track plate when the adjusting ring is lifted up relative to the base, and the adapter can be removed from the track plate or the limit frame of the adapter can extend into the track plate when the adjusting ring moves down relative to the base.

In a preferred embodiment of the above adapter, the lower end of the slider is formed with a slide post protruding in the sliding direction thereof. The adapter also comprises an inner seat which is arranged on the base and the bottom end of which extends into the limiting frame, and the inner seat is provided with a mounting groove for the pair of locking blocks and a sliding groove for the sliding column to slide. Therefore, the pair of locking blocks can be arranged on the base more conveniently by arranging the inner seat, and the sliding of the sliding piece is limited. It should be noted that, although the sliding of the sliding block is limited by the inner seat in the present embodiment, the corresponding sliding groove may be directly arranged on the base to cooperate with the sliding post of the sliding member to limit the sliding of the sliding block without arranging the inner seat.

In a preferred embodiment of the above adapter, the adapter further comprises a middle seat and at least one elastic member. The middle seat is connected to the top surface side of the base and located on the inner side of the adjusting ring, and an arc-shaped concave cavity is formed in the outer side of the middle seat. And the inner wall of the adjusting ring is provided with a mounting frame, and the mounting frame is positioned in the arc-shaped concave cavity. The elastic piece is arranged between the mounting frame and the top surface of the arc-shaped concave cavity, so that the adjusting ring is pressed towards the base in the axial direction, and the pair of locking blocks are in an open state. Therefore, in a normal state, the elastic piece can press the adjusting ring to the base, and the adapter can be clamped on the track plate through the locking piece, so that the adapter is connected with the track plate more reliably.

Illustratively, the mounting bracket may have at least one locating post and at least one attachment hole formed therein, both of which face the top surface of the arcuate cavity. The elastic piece is a spring, the spring is sleeved on the positioning column and is propped between the mounting frame and the top surface of the arc-shaped concave cavity, the upper end of the spring is bent to form a connecting rod parallel to the axis, and the connecting rod is inserted into the connecting hole. Therefore, when the adjusting ring moves axially relative to the base, the positioning column can position the spring, so that the spring is reliably arranged. Meanwhile, the connecting rod at one end of the spring is inserted into the connecting hole on the mounting frame, so that the function that the spring cannot be misplaced and can stretch out and draw back normally along the axial direction of the spring can be kept when the adjusting ring rotates relative to the base.

In a preferred implementation manner of the adapter provided in the foregoing embodiment, the limiting frame is further provided with a second window, and the second window is disposed at intervals relative to the first window in a length direction in which the limiting frame extends along the bottom surface of the base. The adapter also comprises two conductive pins, wherein each conductive pin comprises a conductive shaft and a conductive inserting sheet extending from the side wall of the conductive shaft; one conductive inserting sheet is arranged in the first window, the other conductive inserting sheet is arranged in the second window, and one ends of the two conductive shafts extend out of the top surface of the base. The adjusting ring is also coaxially and rotatably arranged relative to the base, so that the two conductive inserting pieces can swing around the corresponding conductive shafts by driving a transmission assembly, and the two conductive inserting pieces can extend out in opposite directions relative to the limiting frame. Therefore, the adjusting ring can control the locking block to be clamped on the track plate by moving along the axial direction relative to the base, and can control the conductive inserting pieces of the two conductive pins to rotate by rotating relative to the base so as to complete the electric connection between the adapter and the track plate.

In order to make it easier for the skilled person to understand the construction of the above-described adapter, a track plate is described here as an example. For example, an installation space is formed in the track plate, a conductive plug bush is arranged on the left side wall and the right side wall of the installation space, and a limit opening for the limit frame of the adapter to extend into and slide is formed in the top wall of the installation space. Before the adapter is mounted on the track plate, the adjusting ring can enable the conductive inserting pieces to be located in the limiting frame through rotation, the tail ends of the two conductive inserting pieces can be opposite, and the two conductive inserting pieces can be located on the same straight line. When the adapter is mounted to the track plate, rotation of the adjustment ring simultaneously drives the two conductive pins to rotate such that one conductive tab extends from one window and is inserted into the conductive insert on the left side wall of the track plate and the other conductive tab extends from the other side of the other window and is inserted into the conductive insert on the right side wall of the track plate. When the two conductive inserting sheets extend out from the two sides of the limiting frame towards opposite directions, the adapter and the track plate are electrically connected. Meanwhile, due to the plugging effect of the conductive inserting sheets and the conductive inserting sleeves, the adapter can be firmly installed on the track plate.

In a preferred embodiment, the transmission assembly may include a main gear and two auxiliary gears, wherein the main gear and the two auxiliary gears are both disposed on the top surface of the base, and the two auxiliary gears are respectively connected to one of the conductive shafts, and the main gear and the two auxiliary gears are engaged to transmit. And the adjusting ring is arranged on the top surface of the base and connected with the main gear, so that the two conductive inserting sheets are driven to swing synchronously by driving the main gear to rotate coaxially, and the tail ends of the two conductive inserting sheets can extend out from the corresponding windows in opposite directions. The middle seat is connected to the top surface of the base and is positioned in the adjusting ring. The two conductive shafts extend out of the middle seat, and the middle seat is further arranged to limit the two pinion gears in the axial direction of the pinion gears.

It should be noted that, in another embodiment, the transmission assembly may further include a cam, where when the small diameter portions on opposite sides of the cam face the two conductive shafts, the corresponding two conductive tabs are kept retracted into the corresponding first window or the second window; when the large diameter parts on two opposite sides of the cam are opposite to the two conductive shafts, the cam drives the two conductive inserting pieces to extend out in opposite directions relative to the limiting frame.

In a second aspect, the present utility model provides a rail receptacle comprising a rail plate and an adapter according to any of the embodiments described above. The track plate is provided with a limiting opening into which the limiting frame of the adapter extends, and the pair of locking blocks of the adapter can be clamped on the inner walls of the two sides of the limiting opening in the extending state.

The present utility model will be further described in detail with reference to the following examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

As can be seen from fig. 1, the track-type socket provided in this embodiment comprises a track plate 9 and an adapter 10 connectable to the track plate 9. An installation space 91 is formed in the track plate 9, a conductive plug bush 92 is arranged on the left side wall and the right side wall of the installation space 91, and a limiting opening 911 is formed on the top wall of the installation space 91.

With continued reference to fig. 1, the adapter 10 includes a base 1 and an adjusting ring 3 rotatably disposed with respect to the base 1, and the adjusting ring 3 is also movable in an axial direction of the base 1, while a top cover 13 provided with a receptacle is fixedly connected with respect to the base 1. Wherein the limit frame 11 provided on the base 1 can extend into the installation space 91 from the limit opening 911 of the track plate 9, when the adapter 10 is installed on the track plate 9, by rotating the adjusting ring 3, one conductive insert 62 extends from both left and right sides of the limit frame 11 of the adapter 10, one conductive insert 62 extends from one side of the first window 111, and the other conductive insert 62 extends from the other side of the second window 112, i.e. the two conductive inserts 62 extend in opposite directions relative to the limit frame 11. Meanwhile, the two conductive inserting pieces 62 can be respectively inserted into and conductive with the conductive inserting sleeves 92 on the left side wall and the right side wall of the installation space 91, so that electricity can be taken when the plug of the electrical appliance is inserted into the inserting hole of the top cover 13.

In addition, two locking blocks 2 are further arranged in the first window 111 of the adapter 10, and when the adapter 10 is mounted on the track plate 9, the adjusting ring 3 moves axially relative to the base 1, so that the pair of locking blocks 2 of the adapter 10 are in an open state and are clamped on the inner walls of two sides of the limiting opening 911.

The above-described method of using the rail type socket of the present embodiment is exemplified, and the detailed structure of the adapter 10 and the advantages of using the rail type socket as a whole using the adapter 10 will be described in detail.

In this adapter 10, referring to fig. 1 and 2, a base 1 is formed with a stopper 11 protruding away from the bottom surface thereof, the stopper 11 is provided with a first window 111 and a second window 112 at intervals in a length direction extending along the bottom surface of the base 1, and the first window 111 communicates opposite sides of the stopper 11.

The adapter 10 further comprises two conductive pins 6, the conductive pins 6 comprising a conductive shaft 61 and a conductive tab 62 extending from a side wall of the conductive shaft 61. One conductive tab 62 is disposed in the first window 111, the other conductive tab 62 is disposed in the second window 112, and one end of each of the two conductive shafts 61 protrudes from the top surface of the base 1.

By coaxially and rotatably arranging the adjusting ring 3 relative to the base 1, it is possible to oscillate the two conductive tabs 62 about the respective conductive axes 61 by driving a transmission assembly and to extend the two conductive tabs 62 in opposite directions relative to the stop 11.

Referring to fig. 2, in a preferred embodiment, the transmission assembly may include one main gear 71 and two sub gears 72, and one main gear 71 and two sub gears 72 are disposed on the top surface of the base 1, and the two sub gears 72 are connected to one conductive shaft 61, respectively, and the main gear 71 is engaged with the two sub gears 72 for transmission. An adjusting ring 3 is provided on the top surface of the base 1 and connected to the main gear 71 to drive the two conductive tabs 62 to swing synchronously by driving the main gear 71 to rotate coaxially, and to enable the ends of the two conductive tabs 62 to protrude from the respective corresponding windows in opposite directions.

Preferably, the middle seat 5 is connected to the top surface side of the base 1 and located inside the adjusting ring 3, and the middle seat 5 can limit the two pinions 72 in the axial direction of the pinions 72. Further, a plurality of electrical connectors 611 are provided above the center housing 5 and are used for electrical connection with external plugs. Wherein the conductive shafts 61 of the two conductive pins 6 also pass through the middle seat 5 and are respectively connected with one electric connecting piece 611 in a rotating way to realize the electric conduction.

Note that the transmission assembly capable of realizing control of the conductive pin 61 according to the present embodiment is not limited to this. For example, in another embodiment, the transmission assembly may further include a cam, and when the small diameter portions on opposite sides of the cam face the two conductive shafts 61, the respective two conductive tabs 62 are each held retracted into the respective first or second windows 111, 112; when the large diameter portions on the opposite sides of the cam face the two conductive shafts 61, the cam drives the two conductive tabs 62 to protrude in opposite directions relative to the stopper 11.

The adjusting ring 3 can be turned to position the conductive tabs 62 inside the stop 11 before the adapter 10 is mounted on the track plate 9, where the ends of the two conductive tabs 62 can be opposite and the two conductive tabs 62 can be in the same line. When the adapter 10 is mounted to the track plate 9, rotation of the adjustment ring 3 simultaneously drives rotation of the two conductive pins 6 such that one conductive tab 62 extends from one window and is inserted into the conductive sleeve 92 on the left side wall of the track plate 9 and the other conductive tab 62 extends from the other side of the other window and is inserted into the conductive sleeve 92 on the right side wall of the track plate 9. When the two conductive tabs 62 extend from opposite sides of the stop 11, respectively, the electrical connection between the adapter 10 and the track plate 9 is completed. At the same time, the adapter 10 can be mounted relatively firmly on the track plate 9 due to the plugging action of the conductive plug-in sheet 62 and the conductive plug-in sleeve 92.

Referring to fig. 1 to 3, in the adaptor 10 of the track-type socket provided in this embodiment, a pair of locking blocks 2 and a set of transmission mechanisms 4 are further disposed on the base 1 of the adaptor 10. One end of each locking piece 2 is provided with a rotating shaft 21, the other end of each locking piece is provided with a lock catch 22, the two rotating shafts 21 are parallel to the bottom surface of the base 1 and oppositely set a pair of locking pieces 2 on the base 1, and the two lock catches 22 are respectively opposite to two opposite sides of the first window 111. The transmission mechanism 4 is disposed between the adjusting ring 3 and the pair of lock blocks 2, and the transmission mechanism 4 is configured to transmit when the adjusting ring 3 moves axially relative to the base 1 to drive the pair of lock blocks 2 to swing open and close about respective rotation shafts 21. For example, the transmission mechanism 4 may be a gear transmission mechanism 4, a crank link transmission mechanism 4, or the like. Optionally, a pair of lock pieces 2 are formed with mutually mating engagement portions or rolling portions around the respective rotation shafts 21 so that the pair of lock pieces 2 swing synchronously around the respective rotation shafts 21.

As can be seen from the above, during use of the orbital socket, before the adaptor 10 is mounted on the orbital plate 9, the adjusting ring 3 can be in a first axial position with respect to the base 1 and the two locking blocks 2 are retracted synchronously inside the first window 111 by the transmission mechanism 4; after the limiting frame 11 on the base 1 of the adapter 10 extends into the limiting opening 911 of the track plate 9, the adjusting ring 3 can move to the second axial position relative to the base 1, and the two locking blocks 2 synchronously extend out of two sides of the limiting frame 11 through the transmission mechanism 4 to be clamped on two inner walls of the two sides of the limiting opening 911, so that the adapter 10 can be more conveniently and reliably arranged on the track plate 9.

In this way, the adjusting ring 3 can rotate by controlling the conductive inserting pieces 62 of the two conductive pins 6 to complete the electrical connection between the adapter 10 and the track plate 9 through rotating relative to the base 1, and can also control the locking piece 2 to clamp the adapter 10 on the track plate 9 through moving relative to the base 1 along the axial direction.

In a preferred embodiment, referring to fig. 3 and 4, the transmission mechanism 4 may further comprise a lifting member 41 and a sliding member 42. Wherein a lifting member 41 is connected to the adjustment ring 3 so as to be axially movable with the adjustment ring 3 relative to the base 1. The sliding member 42 may be formed with a limiting slope 421 slidably engaged with the lifting member 41, and when the lifting member 41 moves axially, the sliding member 42 slides on the base 1 in a direction approaching or separating from the lock block 2, so as to drive the pair of lock blocks 2 to swing open and close.

Illustratively, the lifting member 41 is formed with at least one concave ring portion 411, and the inner peripheral wall of the adjusting ring 3 is formed with a convex ring portion 32 in rotation-limiting engagement with the concave ring portion 411, so that a rotation-limiting connection between the lifting member 41 and the adjusting ring 3 is achieved, enabling the lifting member 41 to move axially with the adjusting ring 3 relative to the base 1, while enabling the lifting member 41 to remain stationary relative to the base 1 when the adjusting ring 3 rotates relative to the base 1. For another example, a protrusion may be provided on the lifting member 41 to cooperate with a recess on the inner wall of the adjusting ring 3 to achieve the purpose that the lifting member 41 moves along with the adjusting ring 3 in the axial direction relative to the base 1.

Preferably, the lifting member 41 may further be formed with a limiting rod 413 extending toward the base 1, and the base 1 is provided with a limiting groove 12 extending into the limiting frame 11, and the limiting rod 413 is slidably matched with the limiting groove 12 to keep the lifting member 41 moving axially relative to the base 1. Similarly, corresponding slots may be provided on the poppet 41 to provide a positive engagement with a stem provided on the base 1 to maintain axial movement of the poppet 41 relative to the base 1.

Preferably, the lifting member 41 may be further formed with a limiting step 412 protruding toward the limiting slope 421, and the limiting step 412 is disposed to slidably engage with the limiting slope 421 of the sliding member 42. In an alternative embodiment, instead of the above-mentioned lifting member 41, a boss similar to the stopper 412 may be directly provided on the adjusting ring 3 to slidably engage with the above-mentioned slider, and slide the sliding member 42 along the base 1 when the adjusting ring 3 is axially moved relative to the base 1.

In an alternative embodiment, referring to fig. 4, the transmission mechanism 4 may further include a torsion spring 43, where the torsion spring 43 is disposed between the sliding member 42 and the locking pieces 2 to drive the pair of locking pieces 2 to swing open and close during sliding of the sliding member 42.

Illustratively, the torsion spring 43 includes two spiral rings 431 disposed coaxially, and one end of each spiral ring 431 extends outwardly to connect two ends of a crossbar 432, wherein the crossbar 432 is parallel to the axis of the torsion spring 43. The other ends of the two screw rings 431 are each extended outward and formed with a leg 433, respectively. Wherein, the cross bar 432 is pressed against one side of the sliding piece 42, which is opposite to the limiting inclined plane 421, and the two supporting legs 433 are respectively arranged in the corresponding one of the two locking pieces 2, so that when the sliding piece 42 slides towards the direction of approaching the locking pieces 2, the two locking pieces 2 are closed under the elastic deformation action of the torsion spring 43; and when the slider 42 slides in a direction away from the lock pieces 2, the two lock pieces 2 are opened by the elastic restoring force of the torsion spring 43.

In the above technical solution, when the adjusting ring 3 is lifted up relative to the base 1, the sliding member 42 moves towards the direction approaching the pair of locking pieces 2, so that the torsion spring 43 compresses and drives the pair of locking pieces 2 to close by the two legs 433 thereof, thereby extending the limit frame 11 of the base 1 of the adapter 10 into the track plate 9 or removing the adapter 10 from the track plate 9. And, when the adjusting ring 3 moves downward relative to the base 1, the slider 42 moves away from the pair of locking pieces 2, so that the torsion spring 43 is relaxed and drives the pair of locking pieces 2 to open through the two legs 433 thereof, and thus the pair of locking pieces 2 can be clamped on both sides of the inner wall of the limit opening 911 of the track plate 9 in a state where the limit frame 11 of the base 1 of the adapter 10 extends into the track plate 9.

It should be noted that, by changing the form of the torsion spring 43, the locking piece 2 can be blocked on both sides of the inner wall of the limit opening 911 of the track plate 9 when the adjusting ring 3 is lifted up relative to the base 1, and the adapter 10 can be removed from the track plate 9 or the limit frame 11 of the adapter 10 can be extended into the track plate 9 when the adjusting ring 3 is moved down relative to the base 1.

In a preferred embodiment of the adapter 10 described above, referring to fig. 4, the lower end of the slider 42 may be formed with a slide post 422 protruding in the sliding direction thereof. Referring to fig. 3, the adapter 10 further includes an inner seat 8, wherein the inner seat 8 is disposed on the base 1, and the bottom end of the inner seat extends into the limiting frame 11, and a pair of mounting grooves 81 of the locking block 2 and a sliding groove for sliding with the sliding post 422 are formed on the inner seat 8. By providing the inner holder 8 in this way, the pair of lock blocks 2 can be more conveniently provided on the base 1, and the sliding of the slider 42 can be restrained.

Although the sliding of the sliding block is limited by the inner seat 8 in the present embodiment, the sliding groove of the sliding member 42 may be directly provided on the base 1 to cooperate with the sliding post 422 of the sliding member 42 to limit the sliding of the sliding block without providing the inner seat 8.

In a preferred embodiment of the adapter 10 described above, with continued reference to fig. 2, the outer side of the center seat 5 is formed with an arcuate recess 51, and the inner wall of the adjustment ring 3 is provided with a mounting bracket 31, the mounting bracket 31 being located in the arcuate recess 51. The adapter 10 further comprises at least one elastic member 312, the elastic member 312 being arranged between the mounting frame 31 and the top surface of the arc-shaped recess 51 to axially press the adjusting ring 3 against the base 1, thereby bringing the pair of locking pieces 2 into an open state. In this way, in the normal state, the elastic member 312 can press the adjusting ring 3 against the base 1, and enable the adapter 10 to be kept clamped on the track plate 9 by the locking piece 2, so that the connection of the adapter 10 and the track plate 9 is more reliable.

Illustratively, the mounting bracket 31 may have at least one locating post 311 and at least one attachment hole formed therein, with the locating post 311 and the attachment hole each facing the top surface of the arcuate cavity 51. The elastic member 312 may be a spring, which is sleeved on the positioning post 311 and is propped between the mounting frame 31 and the top surface of the arc-shaped concave cavity 51, the upper end of the spring is bent to form a connecting rod parallel to the axis, and the connecting rod is inserted into the connecting hole on the mounting frame 31.
