Description

Technical Field

[0001] This invention belongs to the field of electronic connector assembly, and specifically relates to an integrated machine for mounting connector pins and locking strips. Background Technology

[0002] As an indispensable basic component in electronic devices, the manufacturing precision and level of automation of electronic connectors directly affect the reliability and production cost of products. Figure 1 In the connector assembly process shown, inserting the PIN pin 20 into the plastic shell 10 and fastening the locking strip 30 onto the plastic shell 10 are two important steps. One type of connector assembly machine uses a single pushing mechanism to push the plastic shell at the pin insertion station, advancing it along a track to the pin insertion station. This working mode has an inherent efficiency bottleneck: when the plastic shell completes one push and performs the pin insertion operation, it must return to the starting position before the next moving plastic shell can be pushed. This means that a considerable amount of time is wasted on the return stroke of the pushing plate within a work cycle, making it impossible to effectively achieve continuous plastic shell pushing, thus limiting the improvement of the overall production cycle of the equipment. Summary of the Invention

The auxiliary pressure block is mounted on the lifting slider. One end of the driving swing rod is connected to the cylinder rod of the second transverse cylinder, and the other end is connected to the lifting slider.

[0014] Preferably, the plastic shell spring-loaded mechanism includes a limiting hole opened on the locking bar track section, a pressing block inserted into the limiting hole and movable up and down, a support seat fixed on the locking bar track section, an adjustable seat screwed onto the support seat, and a return spring limited between the pressing block and the adjustable seat; the return spring provides a downward elastic force to the pressing block; the upper end of the adjustable seat is provided with an adjustment hole.

[0015] The positive effects of this invention are as follows: The connector pin and locking strip integrated machine of this invention can realize the pin and locking strip assembly during the connector assembly stage. During the pin insertion stage, the structure of the plastic shell pushing mechanism is optimized, employing a parallel, alternating double-push plate structure and a design in the track unit for pushing the plastic shell to insert the pin. Specifically, this mechanism includes a first push plate and a second push plate located at different positions along the width of the track unit. Both are driven by independent first and second electric screw mechanisms, enabling independent motion control. In this working mode, when the second track is in the first position, the plastic shell enters the second track section from the first track section. The second track then moves down to the second position and is aligned with the third track. Then, the first pusher plate pushes the plastic shell from the second track section into the third track section (the pin insertion mechanism inserts pins into the plastic shell in the third track) and performs the pin insertion operation. After that, it returns to below the first track section. At the same time, the second track section receives the plastic shell from the first track section again and moves down to the second position. The second pusher plate then pushes the plastic shell from the second track section into the third track section for pin insertion. This achieves alternating operation and seamless connection of the two pusher plates. Moreover, the through holes at the bottom of the track unit are adapted to the movement paths of the first and second pusher plates, allowing them to continuously push the plastic shell for pin insertion without interfering with each other or hindering the lifting and lowering movement of the second track section. This design completely eliminates the waiting time caused by the idle return in the traditional single pusher plate mechanism, realizing continuous pushing of the plastic shell and forming an efficient and smooth plastic shell pushing system. This significantly improves the production cycle of the pin insertion station, thereby helping to improve production efficiency. Attached Figure Description

[0038] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples and should not be used to limit the scope of protection of the present invention.

[0039] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0040] The structure of the connector pin mounting and locking strip integrated machine according to an embodiment of the present invention is as follows: Figures 1 to 20 As shown, it includes a plastic shell feeding mechanism, a track conveyor line 1, a pin insertion mechanism 2, and a locking strip mechanism 3; the track conveyor line 1 is used to convey plastic shells 10 from left to right, and the track conveyor line 1 includes a pin insertion section 11; the plastic shell feeding mechanism is connected to the left end of the track conveyor line 1, and the plastic shell feeding mechanism is used to input plastic shells 10 to the left end of the track conveyor line 1. The plastic shell feeding mechanism can adopt a vibratory feeder mechanism, the structure of which is existing technology and will not be described in detail here; a plastic shell pushing mechanism 12 is provided at the pin insertion section 11. The function of the plastic shell pushing mechanism 12 is to convey the plastic shells 10 one by one in an orderly manner, so that the pin insertion mechanism 2 can insert PIN pins 20 into the plastic shells 10. Specifically, the plastic shell pushing mechanism 12 includes a track unit 121, a drive unit 122, and a pushing mechanism 123; the track unit 121 and the locking strip track section 13 mentioned below have a channel for conveying the plastic shell 10. The track unit 121 includes a first track section 1211, a second track section 1212, and a third track section 1213 arranged sequentially from left to right. The first track section 1211 is set higher than the third track section 1213. The drive unit 122 drives the second track section 1212 to move up and down at a first position flush with the first track section 1211 and a second position flush with the third track section 1213. The pin insertion mechanism 2 is arranged corresponding to the third track section 1213 to insert PIN pins 20 into the plastic shell 10 within the third track section 1213. The structure of the pin insertion mechanism can adopt existing technology, which will not be described in detail here; combined with Figure 4 , Figures 6 to 9As shown, the pushing mechanism 123 includes a first pushing plate 1231, a second pushing plate 1232, a first electric lead screw mechanism 1233, and a second electric lead screw mechanism 1234; the first pushing plate 1231 and the second pushing plate 1232 are staggered along the width direction of the track unit 121 and can both move up and down; the first electric lead screw mechanism 1233 and the second electric lead screw mechanism 1234 respectively drive the first pushing plate 1231 and the second pushing plate 1232 to move in the left and right directions; the bottom of the first track segment 1211, the second track segment 1212, and the third track segment 1213 are connected and provided with through holes 1235 for the first pushing plate 1231 and the second pushing plate 1232 to pass through. In the connector pin mounting and locking strip integrated machine of the present invention, the plastic shell pushing mechanism 12 adopts a double pushing plate design with staggered parallel and alternating operation, and optimizes the structure of the track unit 121; the track unit 121 specifically consists of: a first track segment 1211 fixed at a high position, a third track segment 1213 fixed at a low position, and a second track segment 1212 that can be raised and lowered between the two; the first pushing plate 1231 and the second pushing plate 1232 are staggered along the width direction of the track unit 121, and are driven by independent first and second electric screw mechanisms, respectively, and are provided with through holes 1235 for the first pushing plate 1231 and the second pushing plate 1232 to move, ensuring that they do not interfere with each other and do not hinder the up and down movement of the second track segment 1212.

[0041] During the plastic shell pushing stage of the plastic shell pushing mechanism 12, the second track segment 1212 first aligns with the first track segment 1211 at the first position to form a docking, allowing a plastic shell 10 to enter the second track segment 1212 from the first track segment 1211. Then, when the second track segment 1212 moves down to the second position, it aligns with the third track segment 1213 to form a docking. At this time, the first pushing plate 1231 moves from left to right to push the plastic shell 10 in the second track segment 1212 into the third track segment 1213. During the process of the first pushing plate 1231 pushing the plastic shell 10 to move in the third track segment 1213, the pin insertion mechanism 2 performs the action of inserting the PIN pin 20. As the first pusher plate 1231 pushes the plastic shell 10 to move and insert pins within the third track section 1213, the second track section 1212 moves up to the first position to receive the next plastic shell 10 and then moves down to the second position. After the pin insertion is completed, the first pusher plate 1231 retracts to the bottom of the first track section 1211 to wait. At the same time, the second pusher plate 1232 moves from left to right to push the plastic shell 10 in the second track section 1212 into the third track section 1213 for pin insertion. This cycle repeats, with the first pusher plate 1231 and the second pusher plate 1232 always maintaining a parallel rhythm of "one push and one return", thereby eliminating the idle return waiting of the traditional pusher mechanism and achieving the goal of improving production efficiency.

[0042] For example, see Figure 6As shown, the first electric lead screw mechanism 1233, the second electric lead screw mechanism 1234, and the drive unit 122 are fixed on the same fixed frame 15. The first electric lead screw mechanism 1233 and the second electric lead screw mechanism 1234 each include a servo motor 151 fixed on the fixed frame 15, a lead screw 152 driven to rotate by the servo motor 151, a lead screw nut 153 threaded with the lead screw 152, a limiting slider 154 fixed on the lead screw nut 153, and a limiting slide rail 155 fixed on the fixed frame 15. The limiting slider 154 and the limiting slide rail 155 are slidably connected in the left and right direction. The first mounting block 1236 and the second mounting block 1237 are respectively fixedly connected to the corresponding limiting slider 154. When the servo motor 151 drives the lead screw 152 to rotate, it drives the limiting slider 154 and the first mounting block 1236 / second mounting block 1237 connected to it to move along the limiting slide rail. The lead screw 152 is arranged in the left and right direction.

[0043] In some embodiments, to ensure the orderly conveying of the plastic shell 10 by the second track segment 1212, a plastic shell position sensing unit 4 is installed on the second track segment 1212. When the plastic shell 10 enters the second track segment 1212, the plastic shell position sensing unit 4 is triggered. That is, when the plastic shell position sensing unit 4 is triggered, it outputs a "material present" signal to the control system. When the plastic shell 10 moves out of the second track segment 1212, the state of the plastic shell position sensing unit 4 flips and outputs a "material absent" signal. After receiving the "material present" or "material absent" signals, the control system instructs the drive unit 122 to move the second track segment 1212 up or down, thereby realizing the orderly conveying of the plastic shell.

[0044] See Figure 5As shown, to further ensure the orderly conveying of the plastic shell 10, the triggering method of the plastic shell position sensing unit 4 is optimized in this embodiment. Specifically, a mounting hole is provided at the upper end of the second track segment 1212, and a contact block 41 that can move up and down is installed in the mounting hole. A support frame 42 is provided on the second track segment 1212 above the contact block 41. The plastic shell position sensing unit 4 is mounted on the support frame 42, and an elastic member 43 is installed between the support frame 42 and the contact block 41. The elastic member 43 provides a downward elastic force to the contact block 41, and the lower end of the contact block 41 extends into the second track segment 1212. When the plastic shell 10 enters the second track section 1212, it pushes the contact block 41 upward and triggers the plastic shell position sensing unit 4. After the plastic shell 10 enters the second track section 1212, the lower end face of the contact block 41 abuts against the upper end of the plastic shell 10. The plastic shell 10 drives the contact block 41 to move upward, triggering the plastic shell position sensing unit 4. At the same time, the contact block 41 forms elastic contact with the plastic shell 10 through the elastic force provided by the elastic member 43, which can constrain the plastic shell 10, thereby ensuring the positional accuracy of the plastic shell 10 in the second track section 1212 and preventing it from shifting during the conveying process. In this embodiment, the plastic shell position sensing unit 4 can be a micro switch, proximity switch, or photoelectric switch. The elastic member 43 can be an elastic component such as a helical compression spring or a spring sheet.

[0045] In some embodiments, the first push plate 1231 and the second push plate 1232 are respectively movably mounted on the first mounting block 1236 and the second mounting block 1237. The left end of the first push plate 1231 is hinged to the first mounting block 1236 via a first pin 12310, and a first reaction spring 1238 is provided between the first push plate 1231 and the first mounting block 1236, providing an upward elastic force to the first push plate 1231. The left end of the second push plate 1232 is hinged to the second mounting block 1237 via a second pin 12320, and a second reaction spring 1239 is provided between the second push plate 1232 and the second mounting block 1237, providing an upward elastic force to the second push plate 1232. This structural arrangement can effectively solve the problem of interference between the pushing mechanism 123 and the plastic shell 10 during the return stroke. During the material pushing stage, the right end of the first push plate 1231 / second push plate 1232 abuts against the plastic shell 10 and moves to the right. During the return stroke, when the upper left side of the first push plate 1231 / second push plate 1232 abuts against the plastic shell 10, it can rotate downward around the first pin 12310 / second pin 12320 to avoid interference. After the first push plate 1231 / second push plate 1232 is separated from the plastic shell 10, it can move upward and reset under the elastic force of the first reaction spring 1238 / second reaction spring 1239. In this way, the first push plate 1231 / second push plate 1232 always adapts to the height change throughout the entire action cycle to complete the orderly material pushing.

[0046] In some embodiments, such as Figure 2 , Figure 3 As shown, the right end of the track conveyor line 1 is provided with a locking bar track section 13, and the locking bar mounting mechanism 3 is set corresponding to the locking bar track section 13. After the pin is inserted into the plastic shell 10, it is conveyed to the locking bar track section 13 through the track conveyor line 1, and then the locking bar 30 is installed onto the plastic shell 10 through the locking bar mounting mechanism 3. The locking bar mounting mechanism 3 is connected to the locking bar feeding mechanism 6, which is used to feed the locking bar 30 to the locking bar mounting mechanism 3. The locking bar feeding mechanism 6 adopts a vibratory feeder feeding mechanism, which is existing technology and will not be described in detail here.

[0047] See 10 to Figure 17The locking bar mechanism 3 includes a mechanism base 31 that can move horizontally, a locking unit 32 that locks the mechanism base 31, a linear drive module 33 mounted on the mechanism base 31, a sliding seat 34 that is moved by the linear drive module 33 in the direction of approaching and moving away from the locking bar track segment 13, a support block 35 mounted on the sliding seat 34 near one end of the locking bar track segment 13, an auxiliary pressure block 36 located above the support block 35, a first drive mechanism 37 mounted on the sliding seat 34 and driving the auxiliary pressure block 36 to move up and down, a second drive mechanism 38 fixed on the mechanism base 31 and located below the sliding seat 34, and a mechanism driven by the second drive mechanism 38. The limiting guard plate 39 moves up and down; the moving direction of the mechanism seat 31 is perpendicular to the conveying direction of the locking bar track section 13; when the limiting guard plate 39 moves up to the highest position, it forms a locking bar receiving cavity 300 between itself, the support block 35 and the auxiliary pressure block 36 to receive the locking bar 30; the support block 35 is provided with a support surface 351 that provides upward support for the locking bar 30; when the limiting guard plate 39 moves down to the lowest position, it is below the sliding seat 34; an avoidance opening 14 is provided on the side of the locking bar track section 13 opposite to the support block 35, and the avoidance opening 14 is used to avoid the support block 35 and the auxiliary pressure block 36 during the locking bar installation stage. In practical use, the locking bar mechanism 3 is moved closer to and further away from the locking bar track section 13 by moving the mechanism seat 31. When the mechanism seat 31 moves to a position close to the locking bar track section 13, it is locked by the locking unit 32. At this time, the locking bar mechanism 3 is in the working position. When the locking unit 32 releases the lock on the mechanism seat 31, the locking bar mechanism 3 is moved to a position away from the locking bar track section 13, which facilitates the inspection and maintenance of the locking bar mechanism 3 and improves the convenience of operation. During the locking bar installation stage: the locking bar mechanism 3 is in the working position, the sliding seat 34 is in a position away from the locking bar track section 13, the limiting guard plate 39 moves upward and forms the locking bar receiving cavity 300 between the auxiliary pressure block 36 and the support block 35, and a locking bar 30 is fed into the locking bar receiving cavity 300 by the locking bar feeding mechanism 6. Then, the limiting guard plate 39 moves to a position lower than the sliding seat 34 under the drive of the second drive mechanism 38, and at the same time, the locking bar in the locking bar receiving cavity 300 faces outward toward the side of the locking bar track section 13. The locking mechanism 30 is first exposed, then the linear drive module 33 drives the sliding seat 34 to move towards the clearance opening 14 on the locking bar track section 13. Then, the auxiliary pressure block 36 is controlled to move upwards to disengage from the locking bar 30, causing the locking bar 30 to engage with the locking bar track section 13 and be positioned on the plastic shell 10 at the clearance opening 14. Then, the linear drive module 33 drives the sliding seat 34 to move away from the locking bar track section 13 to receive the next locking bar 30, thus repeating the locking bar installation action. This locking bar installation mechanism 3 has a reasonable structural design and stable operation. The linear drive module 33 can be an electric lead screw mechanism; the locking unit 32 can be a bolt, latch mechanism, etc.

[0048] Combination Figure 13 and Figure 16 As shown, to ensure effective limiting of the locking bar 30 during the locking bar installation stage, the support surface 351 includes a lower support surface 3511 and a side support surface 3512. The lower support surface 3511 and the side support surface 3512 are arranged in an L-shape. This arrangement of the support surface 351 allows it to provide relatively stable support for the locking bar 30 from the bottom and sides. Simultaneously, suction holes 3513 are provided on the side support surface 3512, with multiple suction holes 3513 spaced apart in the left-right direction. A connecting hole is provided within the support block 35, communicating with all the suction holes 3513. A quick-connect pneumatic connector is provided at the port of the connecting hole, and the quick-connect pneumatic connector is connected to a suction source via a pipeline for suction. Air can hold the locking bar 30 firmly against the support surface 351. Even after the limiting guard plate 39 and the auxiliary pressure block 36 leave the support block 35, the locking bar 30 can still be stably limited on the support surface 351. Moreover, the auxiliary pressure block 36 is provided with a limiting groove 361 facing the support surface 351. The limiting groove 361 can cooperate with the locking bar 30 to strengthen the limiting of the locking bar 30. The limiting guard plate 39 is provided with a locking bar blocking surface 391 that is opposite to the side support surface 3512 when it is moved to the highest position. The locking bar receiving cavity 300 is formed between the locking bar blocking surface 391, the limiting groove 361 and the support surface 351, thereby ensuring that the locking bar 30 is effectively limited between the support block 35 and the auxiliary pressure block 36 during the conveying process. As an optimized implementation scheme, in actual operation, mounting holes can also be provided on the side support surface 3512. A ball bearing and a ball spring are installed in the mounting hole. Under normal conditions, a small part of the ball bearing extends out of the side support surface 3512 under the elastic force of the ball spring. In this way, after the lock bar 30 enters the lock bar receiving cavity 300, the ball bearing is pressed into the mounting hole. When the air intake hole draws air, the lock bar 30 is tightly sucked onto the side support surface 3512 (at this time, the ball spring is compressed). When the lock bar 30 is installed on the plastic shell 10, the air intake hole stops drawing air, and the elastic force released by the ball spring acts on the lock bar 30 through the ball bearing, thereby ensuring that the support block 35 and the lock bar 30 are reliably separated, avoiding the risk that the lock bar 30 will be pulled off again when the support block 35 returns to its original position after the lock bar 30 is installed.

[0049] To ensure the reliability of the locking bar 30's installation on the plastic shell 10, a locking bar pressing mechanism 5 and a plastic shell spring-loaded mechanism 16 are also provided on the right side of the locking bar mounting mechanism 3 on the locking bar mounting track section 13. That is, after the locking bar mounting mechanism 3 mounts the locking bar 30 onto the plastic shell 10, when the plastic shell 10 with the locking bar 30 moves to a position close to the locking bar pressing mechanism 5 and the plastic shell spring-loaded mechanism 16, the plastic shell spring-loaded mechanism 16 applies elastic pressure to the plastic shell 10 to position it, and the locking bar pressing mechanism 5 applies pressure to the locking bar 30 to reliably fasten it onto the plastic shell 10, preventing it from lifting and ensuring the connector assembly quality; see reference. Figures 18 to 20 The locking bar mechanism 5 includes a first transverse cylinder 51 fixed laterally to the upper end of the locking bar track section 13, a "7"-shaped movable block 52 fixed to the cylinder rod of the first transverse cylinder 51, and a locking bar plate 53 fixed to the lower end of the vertical arm 522 of the "7"-shaped movable block 52. A transverse limiting slide 54 is fixed on the first transverse cylinder 51, and a transverse limiting guide rail structure is formed between the transverse limiting slide 54 and the transverse arm 521 of the "7"-shaped movable block 52. The locking bar plate 53 is located on one side of the locking bar track section 13. The side is provided with a side opening 130 for the locking bar 53 to extend into, so as to press the lock bar 30 tightly onto the plastic shell 10. When the locking bar mechanism 5 applies pressure to the lock bar 30, the first transverse cylinder 51 drives the "7"-shaped movable block 52 to move laterally, so that the locking bar 53 extends into the side opening 130 and abuts against the lock bar 30, so that the lock bar 30 is tightly connected to the plastic shell 10. During this process, the cooperation between the transverse limiting slide 54 and the cross arm 521 can provide stable limiting and guidance for the "7"-shaped movable block 52, ensuring that the locking bar 53 applies a stable pressing force to the lock bar 30.

[0050] See Figure 14 and Figure 15 As shown, the first driving mechanism 37 includes a second transverse cylinder 371 fixed transversely on a sliding seat 34, a lifting limit seat 372 fixed on the sliding seat 34, a lifting slider 373 slidably mounted on the lifting limit seat 372, and a driving rocker arm 374 pivotally mounted on the lifting limit seat 372. The auxiliary pressure block 36 is mounted on the lifting slider 373. One end of the driving rocker arm 374 is connected to the cylinder rod of the second transverse cylinder 371, and the other end is connected to the lifting slider 373. When the second transverse cylinder 371 moves in extension and retraction, it drives the driving rocker arm 374 to swing, thereby driving the lifting slider 373 to move up and down through the driving rocker arm 374, which in turn drives the auxiliary pressure block 36 to move up and down. Furthermore, the cylinder rod of the second transverse cylinder 371 is provided with a first sliding hole 375 arranged in the vertical direction, and the drive rocker arm 374 is fixed with a first connecting shaft 3741 that interlocks with the first sliding hole 375; the lifting slider 373 is fixed with a second connecting shaft 3731, and the drive rocker arm 374 is provided with a second connecting hole 3742 that interlocks with the second connecting shaft 3731 in the horizontal direction. In this way, when the cylinder rod of the second transverse cylinder 371 moves horizontally, it drives the drive rocker arm 374 to swing up and down around the pivot shaft, thereby driving the lifting slider 373 and the auxiliary pressure block 36 to move up and down. This structure is reasonably designed and the operation is flexible and stable.

[0051] like Figure 11As shown, the second drive mechanism 38 includes a fixed base 381 fixed on the mechanism base 31, a lock bar drive cylinder 382 fixed on the fixed base 381, and a lifting movable block 383 that can be lifted and slidably mounted on the fixed base 381. The limiting guard plate 39 is mounted on the lifting movable block 383. The fixed base 381 is provided with a limiting sliding hole 3811 through which the lifting movable block 383 passes and moves up and down. The limiting sliding hole 3811 cooperates with the lifting movable block 383 to provide a stable guide for the lifting and lowering movement of the lifting movable block 383, ensuring the stable lifting and lowering action of the limiting guard plate 39.

[0052] See Figure 17 As shown, the auxiliary pressure block 36 can slide up and down on the lifting slider 373. The auxiliary pressure block 36 is provided with a screw through hole, and the lifting slider 373 is provided with a screw fixing hole. The limiting screw passes through the screw through hole and is fixedly connected to the screw fixing hole. The screw through hole is an elongated hole arranged in the vertical direction. This arrangement can limit the auxiliary pressure block 36 to be installed on the lifting slider 373 and allow the auxiliary pressure block 36 to move up and down relative to the lifting slider 373. The lifting slider 373 and the auxiliary pressure block 36 are respectively provided with a first side and a second side facing each other. An auxiliary spring 7 arranged in the vertical direction is limited and installed between the first side and the second side. The first side is provided with a first positioning groove 376 to accommodate the auxiliary spring 7, and the second side is provided with a second positioning groove 362 to accommodate the auxiliary spring 7. The first positioning groove 376 and the second positioning groove 362 are of equal length in the vertical direction. Under normal conditions, the upper end of the auxiliary spring 7 abuts against the upper end surfaces of both the first positioning groove 376 and the second positioning groove 362, and the lower end of the auxiliary spring 7 abuts against the lower end surfaces of both the first positioning groove 376 and the second positioning groove 362. In this way, when the auxiliary pressure block 36 moves downward to contact the locking bar 30, the auxiliary pressure block 36 can overcome the elastic force of the auxiliary spring 7 and slide slightly upward relative to the lifting slider 373 (i.e., "float"), while compressing the auxiliary spring 7. The auxiliary spring 7 provides a stable and adaptively adjustable downward pressure for the auxiliary pressure block 36 and effectively absorbs and dissipates the rigid impact between the auxiliary pressure block 36 and the locking bar. Moreover, this installation method of the auxiliary spring 7 can also eliminate any possible transmission gaps, making the force transmission very sensitive and efficient.

[0053] See Figure 20As shown, the plastic shell spring-loaded mechanism 16 is installed on the locking bar track section 13 near the side opening 130. The plastic shell spring-loaded mechanism 16 includes a limiting insertion hole 161 on the locking bar track section 13, a pressing block 162 inserted into the limiting insertion hole 161 and movable up and down, a support seat 163 fixed on the locking bar track section 13, an adjustable seat 164 screwed onto the support seat 163, and a return spring 165 located between the pressing block 162 and the adjustable seat 164. The return spring 165 provides a downward elastic force to the pressing block 162, so that the lower end of the pressing block 162 presses against the plastic shell 10, ensuring that the plastic shell 10 is stable. The position of the adjustable seat 164 can be adjusted by turning it so that the pressure of the pressing block 162 can be adjusted by the return spring 165. An adjustment hole is provided at the upper end of the adjustable seat 164 so that a tool can be inserted into the adjustment hole to turn the adjustable seat 164.

It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the scope of protection of this invention.
