Description

Technical Field

[0001] The present invention relates to the technical field of automobile part detection, and particularly relates to an installation test tooling for an automobile door interior trim panel. Background Art

[0002] The connection between an automobile door interior trim panel and an automobile door frame is usually carried out by using snap fasteners. Generally, before installing the automobile door interior trim panel, it is necessary to install the automobile door interior trim panel on a special test tooling through the snap fasteners for testing. The test tooling is imitated according to the actual automobile door frame. Therefore, it can be judged whether the automobile door interior trim panel meets the requirements by checking whether each snap fastener of the automobile door interior trim panel can be smoothly installed in the installation holes of the test tooling. However, due to the deformation characteristics of the connection snap fasteners in the prior art, the connection snap fasteners are clamped and fitted in the installation holes, so that both the installation and disassembly of the interior trim panel need to utilize the deformation characteristics of the snap fasteners, which easily damage the connection snap fasteners, and may cause local deformation of the snap fasteners and inability to recover.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number of CN221037179U discloses an installation test tooling for an automobile door interior trim panel. In this solution, a pair of fastening half cylinders are slidably sleeved in a fixed cylinder. A clamping half hole matching the connection snap fastener is opened at the top of the fastening half cylinder, and the two fastening half cylinders are connected by a spring. The lifting movement of the fastening half cylinder along the inside of the fixed cylinder can be controlled through an adjusting structure composed of a rotating rod, an eccentric rod, etc., so that the fastening half cylinder extends or retracts. When the two fastening half cylinders are retracted inside the fixed cylinder, the spring is compressed, and the fastening half cylinders are combined with each other, so that the clamping half holes on the two fastening half cylinders are combined into a complete clamping hole. When the fastening half cylinder extends out of the fixed cylinder, the spring releases elastic force to separate the two fastening half cylinders from each other, so that the clamping hole is divided into two parts, and further it is convenient to take out the connection snap fastener from the fastening half cylinder, and the connection snap fastener will not be damaged when taken out.

[0004] In the above solution during disassembly, although the clamping half holes of the fastening half cylinder have been separated and the locking of the connection snap fastener has been released, the connection snap fastener will be pressed into the fastening half cylinder due to the weight of the automobile door interior trim panel, so that the connection snap fastener still remains in the fastening half cylinder, and it is still necessary to manually take out the connection snap fastener from the clamping half hole of the fastening half cylinder, which has the problem of cumbersome operation. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an installation test tooling for an automobile door interior trim panel to solve the technical problems that in the existing test tooling, when disassembling the automobile door interior trim panel, it is necessary to manually take out the connection snap fastener from the installation hole, so there are problems of cumbersome operation and low efficiency.

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0043] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0044] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an installation test tooling for an automotive door interior trim panel includes a plurality of clamping components for installing the automotive door interior trim panel on the installation frame 2. The clamping components include: a fixed cylinder 4 with an open top; a plurality of fastening half cylinders 13 movably arranged in the fixed cylinder 4. After the plurality of fastening half cylinders 13 are received in the fixed cylinder 4, they can be combined into a complete fastening cylinder. After the fastening cylinder extends out of the open top, it can be dispersed into a plurality of fastening half cylinders 13. The fastening cylinder is provided with a clamping hole 14 at the top that is adapted to the connection buckle of the automotive door interior trim panel; an adjustment structure for making the fastening cylinder extend out of and retract into the fixed cylinder 4; a support structure arranged in the fastening cylinder. The support structure includes a support portion located at the bottom end of the connection buckle. During disassembly, the support structure can drive the support portion to rise and jack up the connection buckle through the dispersion action of the fastening half cylinders 13, so that the connection buckle leaves the inside of the fastening half cylinders 13 through the clamping hole 14;

[0045] Adopting the above technical solution can ensure that when disassembling the connection buckle, the connection buckle can be automatically ejected from the inside of the fastening half cylinders 13. When installing the automotive door interior trim panel, the worker aligns the connection buckle of the automotive door interior trim panel with the clamping hole 14 at the top of the fastening cylinder and applies downward pressure to deform the connection buckle until the connection buckle is embedded in the clamping hole 14 of the fastening cylinder. The surface of the connection buckle contacts the top of the fastening cylinder, and the bottom end of the connection buckle is just above the support portion of the support structure. However, the support portion does not contact the bottom end of the connection buckle, but there is a certain idle stroke. Then, the connection buckle restores under its own elastic force and is engaged with the clamping hole 14 to form a lock, so as to install the automotive door interior trim panel on the installation frame 2. In order to facilitate observing the connection situation between the connection buckle on the automotive door interior trim panel and the clamping hole 14, the fixed cylinder 4, the fastening half cylinders 13, and even the installation frame 2 can be made of transparent materials, such as plastic. In this way, after the connection buckle is engaged with the clamping hole 14, it is convenient to directly observe the connection situation between the connection buckle and the clamping hole 14 from the outside;

[0046] When it is necessary to disassemble the automotive door interior trim panel, the worker operates the adjustment structure to make the fastening cylinder rise along the fixed cylinder 4 until the fastening cylinder is dispersed into two independent fastening half cylinders 13, so as to separate the clamping holes 14 and release the lock on the connection buckle. And when the fastening cylinder is dispersed from a complete structure into two independent fastening half cylinders 13, it will drive the support portion of the support structure to rise relative to the fastening half cylinders 13. Due to the existence of the idle stroke, the support portion will not immediately apply a thrust to the bottom end of the connection buckle to prevent the clamping hole 14 from not completely releasing the lock on the connection buckle. (For example Figure 12As shown, only when the clamping holes 14 are separated to a corresponding degree such that the part of the connecting buckle inserted into the clamping holes 14 can leave the clamping holes 14 without deformation can the connecting buckle be taken out of the fastening half cylinder 13 intact. When the clamping holes 14 are separated to a degree sufficient for the connecting buckle to pass through unobstructed, the supporting part contacts the bottom end of the connecting buckle and pushes it upward out of the clamping holes 14. When the connecting buckle is pushed up, it will be completely separated from the fastening half cylinder 13, realizing the automatic disassembly of the automotive door interior trim panel from the mounting frame 2. The staff only needs to remove the automotive door interior trim panel, which is highly efficient.

[0047] As Figure 5 and Figure 6 shown, in this embodiment, a flange 15 extends radially outward on the outer circumference of the fastening half cylinder 13 near the top end. The flange 15 separates the outer surface of the fastening half cylinder 13 from the inner wall of the fixed cylinder 4 to form a movable gap for the fastening half cylinder 13 to disperse. The flange 15 has an inclined surface, and through the inclined surface, a radially inward contracting force can be applied to the fastening half cylinder 13 in cooperation with the open end of the fixed cylinder 4, so that multiple fastening half cylinders 13 can be combined into a complete fastening cylinder after being received in the fixed cylinder 4;

[0048] Adopting the above technical solution can ensure that the fastening half cylinders 13 can be combined into a complete fastening cylinder after being received in the fixed cylinder 4. When it is necessary to retract the fastening half cylinders 13 into the fixed cylinder 4, the staff operates the adjustment structure to drive the fastening half cylinders 13 to be received from the open end of the fixed cylinder 4. The inclined surface of the flange 15 on the surface of the fastening half cylinder 13 can cooperate with the open end of the fixed cylinder 4 to apply a radially inward contracting force to the fastening half cylinder 13, so that multiple fastening half cylinders 13 can be combined into a complete fastening cylinder after being received in the fixed cylinder 4. To reduce the wear between the flange 15 and the open end of the fixed cylinder 4, the open end of the fixed cylinder 4 can be designed to be smooth, such as having an inclined angle or a rounded corner at the open end of the fixed cylinder 4.

[0049] As Figure 6 and Figure 7 shown, in this embodiment, the clamping assembly further includes: a positioning protrusion 16 provided on the inner wall of the fastening half cylinder 13; a spring 17 provided between the opposite positioning protrusions 16. The spring 17 is used to generate an elastic force that causes the fastening half cylinders 13 to disperse from each other, so that when the flange 15 of the fastening cylinder passes over the open end of the fixed cylinder 4, the fastening cylinder can be dispersed by the elastic force (it should be particularly noted that the elastic force of the spring 17 should be sufficient to overcome the pressure exerted on the top end of the fastening half cylinder 13 by the automotive door interior trim panel and the connecting buckle, so that the fastening half cylinders 13 can overcome this pressure and separate from each other);

[0050] Adopting the above technical solution can ensure that the fastening cylinder is dispersed into two fastening half cylinders 13 when it extends out of the open end of the fixed cylinder 4. During use, the staff operates the adjustment structure to drive the fastening cylinder to extend out of the open end of the fixed cylinder 4 until the flange 15 near the circumference of the top end of the fastening cylinder crosses the open end of the fixed cylinder 4. The spring 17 in the compressed state releases elastic force, thereby driving the two fastening half cylinders 13 to move in the direction of moving away from each other, that is, making the two fastening half cylinders 13 move in the radially outward direction, so that the clamping holes 14 are separated to an extent sufficient for the connecting buckle to pass through without obstruction (as Figure 12 shown. Only when the clamping holes 14 are separated to a part where the connecting buckle can be inserted into the clamping holes 14 and can leave the clamping holes 14 without deformation can the connecting buckle be taken out of the fastening half cylinder 13 intact).

[0051] As Figure 5 , Figure 7 and Figure 8 shown, in this embodiment, the adjustment structure includes: a guiding ring 21 provided at the bottom end of the fastening half cylinder 13; a movable block 22 provided with a guiding post 23, the guiding post 23 is slidably matched with the guiding ring 21, and a sliding groove 35 slidably matched with the guiding post 23 is formed on the surface of the fixed cylinder 4; a threaded rod 26 rotatably connected to one end of the movable block 22, the threaded rod 26 is adapted to a threaded groove 29 formed in the fixed cylinder 4; a driving rod 33, one end of the driving rod 33 is slidably matched with a driving groove 34 formed in the threaded rod 26; a rotating rod 30 rotatably arranged in the fixed cylinder 4, one end of the rotating rod 30 is fixedly connected to the other end of the driving rod 33, the other end of the rotating rod 30 penetrates through the fixed cylinder 4 and extends outwards, the end of the rotating rod 30 extending outwards penetrates through a through hole 45 formed on the surface of the bottom plate 1, and the driving rod 33 and the driving groove 34 are similar to spline fits;

[0052] Adopting the above technical solution can drive the fastening half cylinder 13 to extend out of and retract into the fixed cylinder 4. When it is necessary to extend the fastening half cylinder 13 from the open end of the fixed cylinder 4, rotate the rotating rod 30 in the first direction. The rotating rod 30 drives the driving rod 33 to rotate, the driving rod 33 drives the threaded rod 26 to rotate, and the threaded rod 26 rotates in cooperation with the thread groove 29. While rotating, the threaded rod 26 also rises, so that the threaded rod 26 slides and rises relative to the driving rod 33. The threaded rod 26 drives the movable block 22 to rise, and the movable block 22 drives the guiding column 23 to slide and rise synchronously along the sliding groove 35. While rising, the guiding column 23 cooperates with the guiding ring 21 to drive the fastening half cylinder 13 to rise along the fixed cylinder 4 until the flange 15 of the fastening half cylinder 13 crosses the open end of the fixed cylinder 4. The spring 17 in the compressed state releases the elastic force, thereby driving the two fastening half cylinders 13 to move in the direction of moving away from each other, realizing the dispersion of the combined fastening half cylinders 13; conversely, when it is necessary to retract the fastening half cylinder 13 from the open end of the fixed cylinder 4, only rotate the rotating rod 30 in the second direction opposite to the first direction, so as to drive the threaded rod 26 to move downward, and then drive the fastening half cylinder 13 to retract into the fixed cylinder 4 through the movable block 22, the guiding column 23 and the guiding ring 21. The inclined surface of the flange 15 on the surface of the fastening half cylinder 13 can cooperate with the open end of the fixed cylinder 4 to apply a radially inward contracting force to the fastening half cylinder 13, so that the multiple fastening half cylinders 13 can be combined into a complete fastening cylinder after retracting into the fixed cylinder 4.

[0053] As Figure 2 , Figure 3 and Figure 5 shown, in this embodiment, the adjusting structure further includes: a belt pulley 36 provided at one end of the rotating rod 30; a belt 37 for drivingly connecting the belt pulleys 36 of all the clamping assemblies to each other;

[0054] Adopting the above technical solution can rotate the rotating rods 30 of multiple clamping assemblies in batches. When rotating one of the rotating rods 30, the rotating rod 30 will drive the belt pulley 36 connected thereto to rotate synchronously. The belt pulley 36 drives the belt 37 to transmit, so as to drive all the belt pulleys 36 connected thereto to rotate through the belt 37;

[0055] It should be particularly noted here that since the inner door panel of an automobile is usually provided with multiple connecting buckles, when disassembling the inner door panel of an automobile, if only one of the connecting buckles is unlocked, the other connecting buckles of the automobile inner panel are still in the locked state, which will hinder the lifting of the fastening half cylinder 13. If one of the rotating rods 30 of the fixed cylinder 4 is forcibly rotated, it may cause damage to the fastening half cylinder 13 or the inner door panel of the automobile. Therefore, all the rotating rods 30 must be rotated simultaneously so that the fastening half cylinders 13 in all the fixed cylinders 4 rise at the same speed, so as to horizontally lift the inner door panel of the automobile.

[0056] As Figure 1 ,Figure 2 and Figure 4 As shown in Figure 4 , in this embodiment, four legs 3 are provided at the bottom of the bottom plate 1, and the four legs 3 are symmetrically distributed about the center of the bottom plate 1 in the front, back, left, and right directions;

[0057] Adopting the above technical solution can separate the bottom plate 1 from the desktop, ensuring that there is enough clearance between the desktop and the bottom plate 1 to reserve enough space for rotating the rotating rod 30. In addition, for the convenience of rotating the rotating rod 30, as Figure 5 shown, a rotating handle 38 can also be provided on the rotating rod 30 to facilitate rotating the rotating rod 30.

[0058] As Figure 6 , Figure 9 and Figure 10 shown, in this embodiment, the support structure includes: at least two folding plates 19. One end of the folding plate 19 is movably hinged to the inner wall of the fastening half-cylinder 13, and the other ends of the two folding plates 19 are hinged to each other. When the fastening cylinder is separated from the complete structure into a plurality of fastening half-cylinders 13, the two folding plates 19 gradually tend to a horizontal state from the "V" shape, thereby lifting the connecting buckle through the hinged part of the two folding plates 19;

[0059] Adopting the above technical solution can ensure that when the fastening cylinder is separated from a complete body into two half fastening half-cylinders 13, the connecting buckle can be automatically ejected from the fastening half-cylinder 13. Specifically, when the two fastening half-cylinders 13 are separated from each other, they will respectively drag the folding plates 19 hinged to them along the horizontal direction and stretch them towards both ends, so that the two folding plates 19 gradually tend to a horizontal state from the "V" shape, thereby using the hinged part of the two folding plates 19 to lift the connecting buckle, so that the connecting buckle is ejected from the clamping hole 14 of the fastening half-cylinder 13, which is convenient for directly removing the inner door trim of the car subsequently.

[0060] As Figure 9 , Figure 10 and Figure 11 shown, in this embodiment, the support structure further includes: a push plate 39, which is rotatably arranged at the hinged part of the two folding plates 19; a guiding structure for guiding the folding plates 19 to move vertically;

[0061] Adopting the above technical solution can further improve the stability of the lifting connection buckle. Although the folding plate 19 can directly lift the connection buckle, the supporting surface of the folding plate 19 for the connection buckle is inclined, and it is easy for the connection buckle to shake during the deformation process. Therefore, by adding a push plate 39, the folding plate 19 can be used to push the push plate 39 to rise. The push plate 39 is guided by a guiding structure to ensure vertical and stable movement, so as to indirectly lift the connection buckle through the push plate 39. Compared with the foregoing solution, the lifting action is more stable, the connection buckle is not easy to shake, and the inner wall of the clamping hole 14 and the upper end surface of the push plate 39 can just enclose a limiting space, and the limiting space can provide limitation for the bottom end of the connection buckle to prevent the connection buckle from slipping off the mounting frame 2.

[0062] As Figure 11 shown, in this embodiment, a hinge seat 18 is provided on the inner wall of the fastening half cylinder 13, and one end of the folding plate 19 is rotatably connected to the hinge seat 18. The two folding plates 19 are provided with rotating holes at the ends away from the hinge seat 18 respectively, and a pin shaft 20 is inserted into the rotating holes. The bottom end of the push plate 39 is provided with a connecting bracket 40, and the connecting bracket 40 is provided with a pin hole 41 adapted to the pin shaft 20;

[0063] Adopting the above technical solution can hinge the two folding plates 19 end to end, hinge the ends of the folding plates 19 away from each other to the inner wall of the fastening half cylinder 13 respectively, and at the same time hinge the folding plates 19 to the two folding plates 19 movably. Specifically, when the two fastening half cylinders 13 move away from each other, the fastening half cylinder 13 drags the folding plate 19 through the hinge seat 18, so that the folding plates 19 rotate through the pin shaft 20, and the angle between the folding plates 19 changes as Figure 9 shown Figure 10 . Through the mutual cooperation of the pin shaft 20 and the connecting bracket 40, the push plate 39 is driven to rise, so as to realize ejecting the connection buckle of the automobile door inner trim panel from the clamping hole 14 of the fastening half cylinder 13 by using the push plate 39. The contact part of the push plate 39 and the folding plate 19 is made smooth to reduce the frictional resistance during their relative movement and reduce wear.

[0064] As Figure 5 and Figure 7 shown, in this embodiment, the guiding structure includes guiding rods 42 provided at both ends of the push plate 39. The guiding rods 42 penetrate through a through groove 43 provided at the bottom end of the fixed cylinder 4, and the guiding rods 42 are slidably matched with a guiding groove 44 provided in the fixed cylinder 4;

[0065] Adopting the above technical solution can ensure that the push plate 39 moves vertically straight. When the push plate 39 rises, the guiding rods 42 at both ends of it will be slidably matched with the guiding groove 44 in the fixed cylinder 4, ensuring that the push plate 39 rises vertically without tilting and shaking, and ensuring that the push plate 39 stably supports and lifts the connection buckle of the automobile door inner trim panel.

[0066] As Figure 4 , Figure 5 and Figure 7 shown, in this embodiment, a positioning seat 5 is provided at the bottom of the fixed cylinder 4. A first mounting hole 6 is formed on the surface of the positioning seat 5. The first mounting hole 6 is adapted to a second mounting hole 7 formed at the upper end of the bottom plate 1. A first connecting member 8 is inserted through the first mounting hole 6 and the second mounting hole 7. The first connecting member 8 is preferably a bolt. Further, a recessed groove 9 is formed on the bottom plate 1. The recessed groove 9 is adapted to the shape of the positioning seat 5;

[0067] Adopting the above technical solution can install the fixed cylinder 4 on the upper end of the bottom plate 1 in a detachable manner. During installation, align the positioning seat 5 at the bottom end of the fixed cylinder 4 with the recessed groove 9 at the upper end of the bottom plate 1 and embed it. Ensure that the first mounting hole 6 of the positioning seat 5 is aligned with the second mounting hole 7 of the bottom plate 1, and insert the first connecting member 8 through the first mounting hole 6 and the second mounting hole 7 in sequence, thereby completing the installation.

[0068] As Figure 7 and Figure 8 shown, in this embodiment, the movable block 22 is composed of two half blocks. The two half blocks are provided with a fourth mounting hole 24. A third connecting member 25 is arranged in the fourth mounting hole 24. One end of the threaded rod 26 is provided with a first rotating portion 27. A first rotating groove 28 adapted to the first rotating portion 27 is formed in the two half blocks;

[0069] Adopting the above technical solution can connect the threaded rod 26 and the movable block 22 in a detachable manner. When disassembly is required, use a tool to screw out the third connecting member 25 embedded in the fourth mounting hole 24, and the two half blocks can be separated, so that the first rotating portion 27 of the threaded rod 26 can be removed from the first rotating groove 28 of the movable block 22.

[0070] As Figure 5 and Figure 7 shown, in this embodiment, the fixed cylinder 4 is composed of two semi-cylindrical halves. Mounting blocks 10 are provided on the two semi-cylindrical halves. A third mounting hole 11 is formed in the mounting blocks 10. A second connecting member 12 is arranged in the third mounting hole 11;

[0071] A second rotating portion 31 is provided on the surface of the rotating rod 30. The second rotating portion 31 is in rotational cooperation with a second rotating groove 32 formed in the fixed cylinder 4;

[0072] Adopting the above technical solution can disassemble the fixed cylinder 4, thereby facilitating the removal of the components in the fixed cylinder 4. During disassembly, use a tool to screw out the second connecting member 12 embedded in the third mounting hole 11, and the two semi-cylindrical halves can be separated, so that the fastening semi-cylinder 13, the movable block 22, the guide post 23, the threaded rod 26 and the rotating rod 30 can be removed.

[0073] As shown Figure 12 in the figure, in this embodiment, a rolling structure is further provided at the top end of the fastening half cylinder 13. Through the rolling structure, the connecting buckle and the fastening half cylinder 13 are in rolling contact, so as to reduce the friction force when the two move relative to each other. Specifically, the rolling structure includes a plurality of ball bearings 47, and the ball bearings 47 are rotationally matched with the ball grooves 46 opened at the top end of the fastening half cylinder 13. The highest point of the ball bearings 47 is higher than the top surface of the fastening half cylinder 13, so that the ball bearings 47 are in contact with the connecting buckle;

[0074] Adopting the above technical solution can reduce the friction force between the top end of the fastening half cylinder 13 and the connecting buckle. The rolling structure is not limited to the ball bearings 47, and other similar structures can also be used, such as rollers and rolling pins. Compared with the point contact of the ball bearings 47, the rollers and rolling pins can provide line contact, which can effectively reduce the stress concentration of the connecting buckle and prevent the connecting buckle from appearing dents.

[0075] Working principle: As shown Figure 5 in Figure 6 and Figure 9 the figure, in the initial state, the fastening half cylinder 13 is completely received in the fixed cylinder 4, and the top end of the fastening half cylinder 13 is flush with the open end of the fixed cylinder 4. At this time, the flanges 15 of the two fastening half cylinders 13 are in close contact with the inner wall of the fixed cylinder 4, so that the two fastening half cylinders 13 are closed to form a complete fastening cylinder. Correspondingly, the clamping half holes on the two fastening half cylinders 13 are combined to form a complete and closed clamping hole 14;

[0076] As shown Figure 12 in the figure, when installing the inner door trim of the car, the staff aligns the connecting buckle of the inner door trim of the car with the clamping hole 14 at the top end of the fastening cylinder, and applies downward pressure to deform the connecting buckle until the connecting buckle is embedded in the clamping hole 14 of the fastening cylinder. The surface of the connecting buckle is in contact with the top end of the fastening cylinder, and the bottom end of the connecting buckle is just above the push plate 39. However, the push plate 39 is not in contact with the bottom end of the connecting buckle, but there is a certain idle stroke. After that, the connecting buckle returns to its original state under its own elastic force and is clamped with the clamping hole 14 to form a lock, so as to install the inner door trim of the car on the installation frame 2;

[0077] As shown Figure 9 and Figure 10As shown in the figure, when it is necessary to disassemble the inner door trim of a car, the staff rotates the turning handle 38 to drive the rotating rod 30 to rotate. The rotating rod 30 drives the driving rod 33 to rotate, and the driving rod 33 drives the threaded rod 26 to rotate. The threaded rod 26 rotates in cooperation with the thread groove 29. While rotating, the threaded rod 26 also rises, so that the threaded rod 26 slides and rises relative to the driving rod 33. The threaded rod 26 drives the movable block 22 to rise, and the movable block 22 drives the guiding column 23 to slide and rise synchronously along the sliding groove 35. While rising, the guiding column 23 cooperates with the guiding ring 21 to drive the fastening half cylinder 13 to rise along the fixed cylinder 4 until the flange 15 of the fastening half cylinder 13 crosses the opening of the fixed cylinder 4. The spring 17 in the compressed state releases the elastic force, thereby driving the two fastening half cylinders 13 to move in the opposite direction. The guiding ring 21 cooperates with the guiding column 23 to guide the movement of the fastening half cylinder 13;

[0078] When the two fastening half cylinders 13 move in the opposite direction, the balls 47 at the top of the fastening half cylinder 13 roll into contact connection with the snap fastener, preventing friction between the snap fastener and the top of the fastening half cylinder 13 and ensuring that the snap fastener will not be worn. The fastening half cylinder 13 drags the folding plate 19 through the hinge seat 18, causing the folding plates 19 to rotate through the pin shaft 20, so that the angle between the folding plates 19 changes as Figure 9 towards Figure 10 shown. Through the mutual cooperation of the pin shaft 20 and the connecting bracket 40, the push plate 39 is driven to rise. Due to the existence of the dead zone, the push plate 39 will not immediately exert a thrust on the bottom end of the snap fastener to prevent the locking of the snap fastener by the clamping hole 14 from being completely released. When the clamping hole 14 is separated to a degree where the snap fastener can pass through without obstruction, the push plate 39 contacts the bottom end of the snap fastener and pushes it upward out of the clamping hole 14. When the push plate 39 rises, the guiding rods 42 at both ends thereof will slide and cooperate with the guiding grooves 44 in the fixed cylinder 4 to ensure that the push plate 39 rises vertically without tilting or shaking, so as to realize using the push plate 39 to push the snap fastener of the inner door trim of the car out of the clamping hole 14 of the fastening half cylinder 13 without manual adjustment. Moreover, the inner wall of the clamping hole 14 and the upper end surface of the push plate 39 can just enclose a limiting space, and the limiting space can provide limitation for the bottom end of the snap fastener to prevent the snap fastener from slipping off the mounting frame 2. The staff can directly remove the inner door trim of the car from the mounting frame 2.
