firstly, when an installer needs to connect a first fixed shell and a second fixed shell together, the installer inserts the second fixed shell into a first accommodating cavity formed in the first fixed shell, when one side of a first rack on the second fixed shell is inserted into the first accommodating cavity for a large amount of displacement, the first rack drives a second gear to have a rotation trend, a first square block at the time has a rotation trend under the drive of the first gear, and the first square block is limited by a second guide groove formed in a second guide block, so that the first square block is limited in the rotation direction, the first rack at the time pushes the second gear to move along the direction of the second guide groove, and meanwhile, a through second round hole is formed in the end face of the second guide block and is communicated with the second guide groove; a second round angle is formed at one side of the intersection of the second round hole and the second guide groove; when the first square block enters the second round corner, the side, where the second round corner is not formed, of the intersection of the second round hole and the second guide groove at the moment can limit the movement of the first limit block along the direction of the first limit groove, but the second round corner can not limit the rotary movement of the first square block to the direction of the second round corner at the moment, and when the rotary direction is allowed to be the direction in which the second fixed shell is inserted, the first rack drives the first square block to rotate in the same direction; in addition, when the first square block rotates towards the direction of the second fillet, the first limiting block is limited by one side without the second fillet when just rotating, and the first limiting block gradually extends out along with the rotation of the first square block; when the first square block enters the second round angle, under the movement of the first rack, the second gear in rotary motion drives the first square block to do rotary motion, the first square block in rotary motion drives the first transmission shaft to move, and the first transmission shaft drives the inner end of the second volute spiral spring to move; in the process, the speed of the second limiting block extending out of the third moving groove is less than the speed of the second limiting groove and the third moving groove in a staggered manner; the second stopper can not carry on spacingly to first transmission shaft and second transmission shaft promptly. In addition, in the process of inserting the second fixing shell, because one side of the second rack on the second fixing shell is inserted into the first accommodating cavity, the displacement is less, when the second fixing shell is inserted into the first fixing shell, the second fixing shell can be inclined and deviated, the second block can be limited by the first guide groove formed in the first guide block, so that the second block can be limited in the rotation direction, the second block can not rotate, the second transmission shaft can not drive the cylinder arranged on the second transmission shaft to rotate, and the cylinder can be matched with the second guide groove formed in the cylinder, so that the connecting sleeve can not rotate around the axis of the connecting sleeve; the connecting sleeve can not drive the volute spiral spring fixing sleeve arranged on the connecting sleeve to do rotary motion; at this time, the outer end of the second scroll spring will not rotate, and the second scroll spring will be compressed and stored smoothly; therefore, the first transmission shaft moves under the matching action of the external threads formed on the first transmission shaft and the internal threads formed on the connecting sleeve, and the connecting sleeve moves along the direction of the second guide groove; therefore, the connecting sleeve and the cylinder adapt to the sliding fit action of the second guide groove and the second guide block, and the first transmission shaft moves under the matching action of the external threads formed on the first transmission shaft and the internal threads formed on the connecting sleeve; when the first block just enters a second circular hole formed in the second guide block, the first transmission shaft at the moment can push the first mounting ring to move along the direction of a third accommodating groove formed in the telescopic sleeve, and after the first transmission shaft acts on the first mounting ring, the first mounting ring just pushes the telescopic rod to move for a certain distance, and after the telescopic rod moves, the first plate spring can be compressed to be incapable of being compressed; the telescopic rods on the two telescopic mechanisms can adapt to the inclination of the first transmission shaft and the second transmission shaft at the moment because the telescopic rods have elasticity; at the moment, the worker continues to push the second fixed shell to move towards the inside of the first fixed shell, the moving second fixed shell drives a second rack arranged on the second fixed shell to move, the second rack pushes a first gear to move along the direction of a second guide groove formed in the second guide block, the first gear drives a second square block to move along the direction of the second guide groove formed in the second guide block, the second square block moves to a first round hole which is formed in the end face of the first guide block and is communicated with the first guide groove; the intersection of the first round hole and the first guide groove is symmetrically provided with two first round corners, so that the first round hole can not limit the rotary motion of the second transmission shaft, the outer end of the compressed second volute spring can drive the volute spring fixing sleeve to rotate, the volute spring fixing sleeve which rotates can drive the connecting sleeve to rotate, the connecting sleeve can drive the second guide block which is arranged on the connecting sleeve to rotate, the second guide block can drive the cylinder to rotate through the second guide groove, the cylinder can drive the second transmission shaft to rotate, the second transmission shaft can drive the second block to rotate, the second block can drive the first gear to rotate, the first gear which rotates can drive the second rack to move, the second rack at the moment can drive one end of the second fixed shell to move, and the movement displacement of the first rack and the two ends of the second rack on the second fixed shell can be kept the same, the second fixed shell enters the first fixed shell and is in a parallel state, and in the process, 4 inner walls of the first accommodating cavity are provided with rubber layers; therefore, the second fixed shell can incline in the first accommodating cavity, and rubber layers are arranged on 4 inner walls of the first accommodating cavity to seal the first fixed shell and the second fixed shell; when the second fixed shell is in a horizontal state in the first fixed shell, the second limiting block and the second limiting groove are distributed just opposite to each other, meanwhile, because the end face of the second guide block is provided with a through second round hole, the first block moves into the second round hole, so that the second round hole cannot limit the movement of the first limiting block, the first limiting block moves under the action of the restoring force of the compressed second plate spring, the moving strip drives the first limiting block and the second limiting block which are arranged on the moving strip to move, the second limiting block enters the second limiting groove, and the first transmission shaft, the second transmission shaft and the connecting sleeve are connected together; the rotating circles of the first gear and the second gear are in a synchronous state, so that the movement displacement of the first rack and the second rack is the same, the movement displacement of the first rack on the second fixed shell and the movement displacement of the two sides of the second rack are the same, the second fixed shell can not incline when entering the first fixed shell and can easily enter the first fixed shell, and therefore a worker can install the second fixed shell in place more smoothly and conveniently; meanwhile, the elastic coefficient of the second scroll spring is larger than that of the first scroll spring, so that the first scroll spring is very easy to be compressed, when the first fixed shell and the second fixed shell are separated, the first fixed shaft and the second fixed shaft can restore to the initial positions, the first gear and the second gear can restore to the initial positions by the first fixed shaft and the second fixed shaft, the first plate spring can restore the first transmission shaft and the second transmission shaft to the initial positions along the extension and retraction direction of the extension and retraction mechanism under the action of restoring force, the first limiting block can restore to the second round hole under the limiting action of the second guiding block, the first limiting block enables the moving strip to be restored to the initial position, the final second limiting block moves out of the second limiting groove, and the first transmission shaft, the second transmission shaft and the connecting sleeve are reset; the outer sides of the first fixed shaft and the second fixed shaft are nested with a first scroll spring; the inner end of a first scroll spring nested outside the first fixed shaft is fixedly arranged on the outer circular surface of the first fixed shaft, and the outer end of the first scroll spring is fixedly arranged on the side surface of the first accommodating groove; the inner end of the first scroll spring nested outside the second fixed shaft is fixedly arranged on the outer circular surface of the second fixed shaft, the outer end of the first scroll spring is fixedly arranged on the side surface of the first accommodating groove opposite to the first fixed shaft, and the two first scroll springs have smaller displacement due to the parallel movement of the first square block and the second square block, so that the outer end of the first scroll spring has smaller displacement, but the compression of the first scroll spring cannot be influenced in the process.

In addition, when an installer needs to connect the first fixing shell and the second fixing shell together, the installer inserts the second fixing shell into the first accommodating cavity formed in the first fixing shell, and when one side of the second rack on the second fixing shell is inserted into the first accommodating cavity for a large amount of displacement, the second rack at the moment pushes the first gear to move along the direction of the first guide groove, and the first gear drives the second square block to move along the direction of the first guide groove; the first guide slot can limit the rotation of the second block; the second square block drives the second transmission shaft to move along the direction of the first guide groove; at the moment, the second square block moves into the first round hole, and the second square block can rotate; at the moment, the second rack drives the first gear to move, the first gear drives the second square block, the second transmission shaft, the cylinder, the second guide block, the connecting sleeve and the volute spiral spring fixing sleeve to rotate in sequence, the volute spiral spring fixing sleeve drives the outer end of the second volute spiral spring to compress, and the second limiting groove and the second limiting block are staggered, in the process, the first block is positioned in the second guide groove, the second guide groove limits the rotation movement of the first block, and then the worker continuously pushes the second fixed shell to move towards the first fixed shell, when the first block enters the second round hole, the compressed second volute spring drives the first transmission shaft to rotate, and the first transmission shaft drives the first block, the second gear and the first rack to move in sequence, so that the inclined second fixed shell is parallel in the first fixed shell; after the first transmission shaft and the second transmission shaft are locked as described above, a worker can more easily mount the first stationary housing and the second stationary housing together.

The two side surfaces of the second fixing shell are symmetrically provided with two buckling mechanisms, and the two buckling mechanisms are respectively and symmetrically matched with the two protrusions arranged on the two side surfaces of the first fixing shell, so that the design purpose is that when the first fixing shell and the second fixing shell are installed in place, the elastic L-shaped strip can stride over the protrusions, the through grooves arranged on the end surfaces of the L-shaped strip are embedded into the protrusions, and the L-shaped strip is matched with the protrusions, so that the first fixing shell and the second fixing shell are in a locking state, and the purpose of connecting the first fixing shell and the second fixing shell is achieved.

The design purpose that the non-through first accommodating groove is formed in one side, close to the opening of the first fixing shell, of the end face of the first accommodating cavity is to accommodate a first fixing strip, a second fixing strip, a first guide block, a second fixing block, a first transmission shaft, a second transmission shaft, a connecting sleeve and the like conveniently; the end face of the first accommodating cavity provided with the first accommodating groove is symmetrically provided with two second accommodating grooves, so that the first rack and the second rack can be accommodated conveniently; the first plate spring is positioned in the third accommodating groove, one end of the first plate spring is fixedly arranged on the end face of the first accommodating groove, and the other end of the first plate spring is fixedly arranged on the end face of the telescopic rod, so that a restoring force is conveniently applied to the telescopic rod; the outer circular surface of the first mounting ring is fixedly mounted at one end of the telescopic rod, so that the first transmission shaft and the second transmission shaft can be conveniently mounted; the first moving groove and the second moving groove are same in size and are designed to facilitate the movement of the moving strip in the first moving groove and the second moving groove; the lubricating oil is coated between the moving strip and the second moving groove, so that the friction force action between the moving strip and the second moving groove is reduced; the design purpose that the elastic coefficient of the second scroll spring is 6-8 times that of the first scroll spring is that the second scroll spring at the moment can smoothly compress the storage capacity, and meanwhile, on the basis that the first scroll spring enables the first gear and the second gear to reset, the first scroll spring has small influence on the second scroll spring; the elastic coefficient of the second scroll spring is 7 times that of the first scroll spring, so that the second scroll spring can smoothly compress the storage capacity by workers at the moment, the workers are comfortable to install, the first scroll spring can smoothly restore the first gear and the second gear, and the ratio is selected to ensure that the movement is more reasonable; the first scroll spring in the invention is only shown schematically, and in actual equipment, the first scroll spring has a plurality of circles so as to meet the actions of resetting the second gear in a plurality of circles of rotation and resetting the first gear in a plurality of circles of rotation; two first guide blocks are symmetrically arranged on the inner circular surface of the moving sleeve; the sliding fit that the motion cover passes through first guide block and first guide slot installs the design purpose in the first transmission shaft outside, and when the connection cover moved along the second guide slot direction, the adapter sleeve of motion will drive the fixed cover motion of the volute spiral spring of installing above that, and the second volute spiral spring at this moment will also can follow the fixed cover of volute spiral spring and follow the motion of second guide slot direction under the sliding fit effect of first guide block and first guide slot to make the second volute spiral spring can adapt to the motion of the fixed cover of volute spiral spring.

The specific implementation mode is as follows: when the first fixing shell 3 and the second fixing shell 5 are not installed, the second limiting block 49 in the first fixing shell 3 is distributed opposite to the second limiting groove 50, and the second plate spring 47 is in a compressed state; when the installer needs to connect the first fixing housing 3 and the second fixing housing 5 together, the installer inserts the second fixing housing 5 into the first receiving cavity 12 opened on the first fixing housing 3, when the side of the first rack gear 4 on the second stationary case 5 is inserted into the first accommodation chamber 12 by a large displacement, the first rack 4 drives the second gear 23 to rotate, and the first block 26 rotates under the drive of the first gear 22, when the first block 26 is restricted by the second guide groove 35 formed in the second guide block 21, the first block 26 is restricted in the rotation direction, the first rack 4 at this time will push the second gear 23 to move along the second guide groove 35, meanwhile, a through second round hole 34 is formed in the end face of the second guide block 21, and the second round hole 34 is communicated with the second guide groove 35; a second round corner 33 is formed at one side of the intersection of the second round hole 34 and the second guide groove 35; when the first block 26 enters the second round corner 33, the side of the intersection of the second round hole 34 and the second guide groove 35, where the second round corner 33 is not opened, will limit the movement of the first limit block 45 along the direction of the first limit groove 52, but the second round corner 33 will not limit the rotational movement of the first block 26 towards the direction of the second round corner 33, and the direction of the rotation is allowed to be the same as the direction of the rotation of the second fixed shell 5, the first rack 4 drives the first block 26 to rotate in the same direction; in addition, when the first block 26 rotates towards the second round angle 33, the first limit block 45 is limited by the side without the second round angle 33 when just rotating, and the first limit block 45 gradually extends out along with the rotation of the first block 26; when the first block 26 enters the second fillet 33, the second gear 23 will drive the first block 26 to rotate under the movement of the first rack 4, the first block 26 will drive the first transmission shaft 27 to move, and the first transmission shaft 27 will drive the inner end of the second spiral spring 48 to move; in the process, the speed of the second limiting block 49 extending out of the third moving groove 55 is less than the speed of the second limiting groove 50 staggered with the third moving groove 55; that is, the second limit block 49 does not limit the first transmission shaft 27 and the second transmission shaft 28. In addition, in the process of inserting the second fixing housing 5, because the second rack 16 side of the second fixing housing 5 is inserted into the first accommodating cavity 12 with less displacement, when the second fixing housing 5 is inserted into the first fixing housing 3, the second fixing housing 5 will have an inclined offset, and at this time, the second block 30 will be limited by the first guide slot 39 formed on the first guide block 15, so that the second block 30 will be limited in the rotation direction, the second block 30 will not make a rotational motion, and will not make the second transmission shaft 28 make a rotational motion, the second transmission shaft 28 will not drive the cylinder 64 mounted thereon to make a rotational motion, and the cylinder 64 will match the second guide slot 65 formed on the cylinder 64 with the second guide block 62, so that the connection sleeve 31 will not make a rotational motion around its own axis; the connecting sleeve 31 will not drive the volute spiral spring fixing sleeve 61 mounted thereon to rotate; at this time, the outer end of the second spiral spring 48 will not rotate, so that the second spiral spring 48 will be compressed and stored smoothly; the first transmission shaft 27 will move under the matching action of the external thread 69 formed on the first transmission shaft and the internal thread 63 formed on the connecting sleeve 31, and the connecting sleeve 31 will move along the direction of the second guide groove 65; so that the connecting sleeve 31 and the cylinder 64 are adapted to the sliding fit of the second guide groove 65 and the second guide block 62, and the first transmission shaft 27 will move by the matching action of the external thread 69 formed on the connecting sleeve and the internal thread 63 formed on the connecting sleeve 31; when the first block 26 just enters the second round hole 34 formed in the second guide block 21, the first transmission shaft 27 at this time will push the first mounting ring 40 to move along the direction of the third accommodating groove 44 formed in the telescopic sleeve 42, and after the first transmission shaft 27 acts on the first mounting ring 40, the first mounting ring 40 will just push the telescopic rod 41 to move for a certain distance, and after the telescopic rod 41 moves, the first plate spring 43 will be compressed to a non-compressible state; because the telescopic rods 41 have elasticity, the telescopic rods 41 on the two telescopic mechanisms 17 can adapt to the inclination condition of the first transmission shaft 27 and the second transmission shaft 28; at this time, the worker continues to push the second fixed shell 5 to move towards the inside of the first fixed shell 3, the moving second fixed shell 5 drives the second rack 16 mounted on the second fixed shell to move, the second rack 16 pushes the first gear 22 to move along the direction of the second guide groove 35 formed in the second guide block 21, the first gear 22 drives the second block 30 to move along the direction of the second guide groove 35 formed in the second guide block 21, the second block 30 moves to the position where the first round hole 37 penetrating through the end face of the first guide block 15 is formed in the end face of the first guide block 15, and the first round hole 37 is communicated with the first guide groove 39; the intersection of the first circular hole 37 and the first guiding groove 39 is symmetrically provided with two first rounded corners 38 such that the first circular hole 37 will not limit the rotation of the second transmission shaft 28, at this time, the outer end of the compressed second volute spring 48 will drive the volute spring fixing sleeve 61 to rotate, the volute spring fixing sleeve 61 to rotate will drive the connecting sleeve 31 to rotate, the connecting sleeve 31 will drive the second guide block 62 mounted thereon to rotate, the second guide block 62 will drive the cylinder 64 to rotate through the second guiding groove 65, the cylinder 64 will drive the second transmission shaft 28 to rotate, the second transmission shaft 28 will drive the second block 30 to rotate, the second block 30 will drive the first gear 22 to rotate, the first gear 22 to rotate will drive the second gear 16 to move, at this time, the second gear 16 will drive one end of the second fixed shell 5 to move, this will make the first rack 4 on the second fixed shell 5 and the second rack 16 on both ends of the movement displacement remain the same, make the second fixed shell 5 enter the first fixed shell 3 in the parallel state, in this process, because 4 inner walls of the first containing chamber 12 are all installed with the rubber layer; therefore, the second fixed shell 5 can incline in the first accommodating cavity 12, and rubber layers are mounted on 4 inner walls of the first accommodating cavity 12 to seal the first fixed shell 3 and the second fixed shell 5; when the second fixing shell 5 is in a horizontal state in the first fixing shell 3, the second limit block 49 and the second limit groove 50 are distributed just opposite to each other, meanwhile, because the through second round hole 34 is formed in the end face of the second guide block 21, the first block 26 moves into the second round hole 34, so that the second round hole 34 cannot limit the movement of the first limit block 45, the first limit block 45 at this time moves under the action of the restoring force of the compressed second plate spring 47, the moving strip 46 drives the first limit block 45 and the second limit block 49 mounted on the moving strip to move, the second limit block 49 at this time enters the second limit groove 50, and the first transmission shaft 27, the second transmission shaft 28 and the connecting sleeve 31 at this time are connected together; therefore, the rotation turns of the first gear 22 and the second gear 23 are in a synchronous state, so that the movement displacement of the first rack 4 and the second rack 16 is the same, and the movement displacement of the first rack 4 on the second fixed shell 5 and the movement displacement of the two sides of the second rack 16 are the same, so that the second fixed shell 5 can enter the first fixed shell 3 without deflection and can enter the first fixed shell easily, and a worker can install the second fixed shell 5 in place more smoothly and conveniently; meanwhile, the elastic coefficient of the second scroll spring is larger than that of the first scroll spring, so that the first scroll spring 24 is very easy to be compressed, when the first fixed housing 3 and the second fixed housing 5 are separated, the first fixed shaft 25 and the second fixed shaft 29 will be restored to the initial positions, the first fixed shaft 25 and the second fixed shaft 29 will restore the first gear 22 and the second gear 23 to the initial positions, the first plate spring 43 will restore the first transmission shaft 27 and the second transmission shaft 28 to the initial positions along the expansion and contraction direction of the expansion and contraction mechanism 17 under the restoring force, the first stopper 45 will be restored to the second circular hole 34 under the limiting effect of the second guide block 21, and the first stopper 45 will restore the moving bar 46 to the initial positions, and finally the second stopper 49 will be moved out of the second stopper groove 50, the first transmission shaft 27, the second transmission shaft 28 and the connecting sleeve 31 complete resetting; the first scroll spring 24 is nested outside the first fixed shaft 25 and the second fixed shaft 29; the inner end of a first scroll spring 24 nested outside the first fixed shaft 25 is fixedly arranged on the outer circular surface of the first fixed shaft 25, and the outer end of the first scroll spring 24 is fixedly arranged on the side surface of the first accommodating groove 13;

In addition, when an installer needs to connect the first fixing shell 3 and the second fixing shell 5 together, the installer inserts the second fixing shell 5 into the first accommodating cavity 12 formed in the first fixing shell 3, and when the installer inserts the second rack 16 on the second fixing shell 5 into the first accommodating cavity 12 for a large amount of displacement, the second rack 16 will push the first gear 22 to move along the first guide slot 39, and the first gear 22 will drive the second block 30 to move along the first guide slot 39; the first guide slot 39 will limit the rotation of the second block 30; the second block 30 will drive the second transmission shaft 28 to move along the first guiding groove 39; at this time, the second block 30 will move into the first circular hole 37, and the second block 30 can rotate; at this time, the second rack 16 will drive the first gear 22 to move, the first gear 22 will drive the second block 30, the second transmission shaft 28, the cylinder 64, the second guide block 62, the connection sleeve 31, and the volute spring fixing sleeve 61 to rotate, the volute spring fixing sleeve 61 will drive the outer end of the second volute spring 48 to compress, the second limiting groove 50 and the second limiting block 49 are misaligned, in this process, the first block 26 will be located in the second guiding groove 35, the second guiding groove 35 will limit the rotation of the first block 26, and then the worker will continue to push the second fixing shell 5 to move towards the first fixing shell 3, when the first block 26 will enter the second circular hole 34, the compressed second volute spring 48 will drive the first transmission shaft 27 to rotate, and the first transmission shaft 27 will drive the first block 26, the second gear 23, and the second limiting groove 49 sequentially, The first rack 4 moves so that the inclined second stationary case 5 will be in a parallel state inside the first stationary case 3; after the first and second transmission shafts 27 and 28 are locked as described above, the worker can more easily mount the first and second stationary cases 3 and 5 together.
