Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a breast screening device. Background Art

[0002] Breast disease is a common gynecological disease that seriously threatens the health and even life of women all over the world. With the development of science and technology, the diagnosis technology and treatment methods of breast disease have been greatly improved. The more common ones are molybdenum target soft X-ray examination, ultrasound imaging examination, near infrared scanning examination, CT examination, etc.

[0003] Ultrasonic imaging is one of the important imaging examination methods for diagnosing breast diseases. It can identify lesions such as cysts and hyperplasia in the breast. Existing breast screening equipment generally includes an equipment body and a treatment bed, and the treatment bed is horizontally slidably mounted on the equipment body. The equipment body itself has at least four casters, and the treatment bed itself also has two casters. When the breast screening equipment needs to be transported over a short distance in hospitals and other places of use, the six casters of the breast screening equipment are on the ground for transportation. However, due to the large size of the treatment bed, it is easy to bump during transportation. When encountering a slope or steep road surface, the two middle casters of the breast screening equipment will not touch the ground, making the user's transportation process more laborious, which makes the existing breast screening equipment inconvenient for short-distance transportation. At the same time, during transportation, the treatment bed is also easy to slide out of the equipment body. Summary of the invention

[0044] See also Figures 1 to 8In one embodiment of the present invention, the breast screening device 10 includes a device body 100, a treatment bed 200 and a transverse limiting mechanism 300; the device body 100 includes a sliding platform 110; the treatment bed 200 is movably mounted on the sliding platform 110, and the treatment bed 200 has a first position of being accommodated in the sliding platform 110 and a second position of sliding out of the sliding platform 110; the treatment bed 200 includes a bed frame 210 and a caster telescopic mechanism 220, the caster telescopic mechanism 220 can move up and down relative to the bed frame 210, and has a storage state of being accommodated in the bed frame 210 and a supporting state of moving to contact with the ground; the transverse limiting mechanism 300 is used to fix the device body 100 and the treatment bed 200 when the treatment bed 200 is located in the first position and the caster telescopic mechanism 220 is located in the storage state.

[0045] Specifically, a sliding platform 110 is provided on the device body 100, and the sliding platform 110 is roughly rectangular. The treatment bed 200 is installed on the sliding platform 110 and can slide along the length direction of the sliding platform 110. The treatment bed 200 has a use state when it is fully pulled out, and an initial state when it is retracted into the device body 100. When the treatment bed 200 is in the first position, the treatment bed 200 is in the initial state when it is retracted into the device body 100; when the treatment bed 200 is in the second position, the treatment bed 200 is in the use state when it is fully pulled out. When the breast screening device 10 needs to be used, the caster retractable mechanism 220 is generally stepped on first to make the caster retractable mechanism 220 in a supporting state in contact with the ground, and then the treatment bed 200 is pulled out along the length direction of the sliding platform 110 for use, and the treatment bed 200 is in the second position. When the breast screening device 10 is not needed, the treatment bed 200 is generally retracted from the second position to the first position, and then the caster retractable mechanism 220 is retracted so that the caster retractable mechanism 220 is in a storage state accommodated in the bed frame 210.

[0046] The treatment bed 200 includes a bed frame 210 and a caster telescopic mechanism 220. The shape of the bed frame 210 is roughly a rectangular parallelepiped frame. The material of the bed frame 210 is made of hard material, which can be metal, alloy and other materials, and there is no specific restriction here. A caster telescopic mechanism 220 is set at one end of the bed frame 210. The caster telescopic mechanism 220 can move up and down relative to the bed frame 210 so that the casters 222 of the treatment bed 200 can be folded up or lowered to the ground. When the caster telescopic mechanism 220 is in the storage state, the casters 222 of the treatment bed 200 are folded up, and when the caster telescopic mechanism 220 is in the support state, the casters 222 of the treatment bed 200 are lowered to contact with the ground to support the treatment bed 200.

[0047] The breast screening device 10 further includes a transverse limiting mechanism 300, through which, when the treatment bed 200 is located at the first position and the caster extension mechanism 220 is in the storage state, the treatment bed 200 and the device body 100 are fixed and limited to prevent the treatment bed 200 from sliding out. As for the form of the limiting structure, it can be the limit by the combination of the latch 310 and the slot, the limit by the combination of the buckle and the buckle slot, or the limit by the adsorption of a strong magnet. There are many ways of limiting, which are not listed here one by one.

[0048] The technical solution of the present invention is to set a caster telescopic mechanism 220 and a lateral limit mechanism 300 on the treatment bed 200 of the breast screening device 10, and install the caster telescopic mechanism 220 on the bed frame 210 of the treatment bed 200 so that it can move up and down. In addition, the treatment bed 200 has a first position where it is accommodated in the sliding platform 110 and a second position where it slides out of the sliding platform 110. The caster telescopic mechanism 220 has a storage state where it is accommodated in the bed frame 210 and a support state where it moves to contact the ground. When the caster telescopic mechanism 220 is in the storage state, the casters 222 of the treatment bed 200 are retracted into the bed frame 210. The lateral limiting mechanism 300 can fix the device body 100 and the treatment bed 200 when the treatment bed 200 is in the first position and the caster retractable mechanism 220 is in the storage state. In this way, when the breast screening device 10 needs to be transported over a short distance, the caster 222 can be retracted through the caster retractable mechanism 220 to facilitate the short-distance transportation of the breast screening device 10, and at the same time, it can also prevent the treatment bed 200 from easily slipping out of the device body 100 during transportation.

[0049] See also Figures 1 to 8 In one embodiment, the sliding platform 110 has a first end 111 and a second end 112 along its length direction, and the lateral limiting mechanism 300 includes a latch 310 and a plug-in portion 320, and the plug-in portion 320 is arranged at the first end 111. When the treatment bed 200 is located at the first position, the latch 310 is inserted into the plug-in portion 320.

[0050] Specifically, the sliding platform 110 has a first end 111 and a second end 112 along its length direction, wherein the first end 111 refers to an end that is convenient for the user to pull out the treatment bed 200, and the second end 112 refers to the other end opposite to the first end 111. The transverse limiting mechanism 300 can be a latch 310 and a plug-in portion 320. The treatment bed 200 has a use state when it is fully pulled out and an initial state when it is retracted into the device body 100. When the treatment bed 200 is in the first position, the treatment bed 200 is in the initial state when it is retracted into the device body 100; when the treatment bed 200 is in the second position, the treatment bed 200 is in the use state when it is fully pulled out. When the treatment bed 200 is in the first position, the latch 310 is inserted into the plug-in portion 320 to limit the treatment bed 200 and prevent it from sliding out.

[0051] See also Figures 1 to 8 In one embodiment, the transverse limiting mechanism 300 further includes a housing 330, a first connecting plate 340 and a first rotating shaft 350. The housing 330 is mounted on the bed frame 210. The first connecting plate 340 and the housing 330 are connected through the first rotating shaft 350 so that the first connecting plate 340 can swing up and down around the first rotating shaft 350. The latch 310 is disposed on the first connecting plate 340. Specifically, the housing 330 of the transverse limiting mechanism 300 is fixedly connected to the bed frame 210, the first connecting plate 340 can rotate around the first rotating shaft 350 as a rotation center, and the latch 310 is disposed on the first connecting plate 340. The first connecting plate 340 swings up and down around the first rotating shaft 350 so that the latch 310 can be inserted into the plug-in portion 320.

[0052] See also Figures 1 to 8 In one embodiment, the lateral limiting mechanism 300 also includes a first elastic member 360, which connects the shell 330 and the upper surface of the first connecting plate 340, and the first elastic member 360 is located on the side of the first rotating shaft 350 away from the latch 310; a lifting member 223 that can move up and down is provided below the first connecting plate 340, and when the lifting member 223 abuts against the lower surface of the first connecting plate 340, the latch 310 is located in the plug-in portion 320; when the lifting member 223 is separated from the lower surface of the first connecting plate 340, the elastic member presses down the connecting plate to make the latch 310 disengage from the plug-in portion 320.

[0053] Specifically, the first elastic member 360 is located between the housing 330 and the first connecting plate 340, and the first elastic member 360 can increase elastic force for the transverse limiting mechanism 300 to ensure that the latch 310 of the transverse limiting mechanism 300 can come out of the plug-in portion 320. When the treatment bed 200 is in the first position, the lifting member 223 abuts against the lower surface of the first connecting plate 340, and the latch 310 is located in the plug-in portion 320; when the treatment bed 200 is in the second position, the lifting member 223 is separated from the lower surface of the first connecting plate 340, and the first elastic member 360 presses down the connecting plate to make the latch 310 come out of the plug-in portion 320.

[0054] See also Figures 1 to 10 In one embodiment, a mounting portion 211 is provided at one end of the bed frame 210, and the caster retractable mechanism 220 is movably provided on the mounting portion 211, and the caster retractable mechanism 220 is fixedly connected to the jacking member 223, and the caster retractable mechanism 220 includes a mounting frame 221 and a caster 222, and the mounting frame 221 is slidably connected to the mounting portion 211, and the caster 222 is arranged at the bottom of the mounting frame 221.

[0055] Specifically, the mounting frame 221 is mounted on the mounting portion 211 and can be moved in the up-down direction so that the caster telescopic mechanism 220 can be switched between the storage state and the support state. The caster 222 is arranged at the bottom of the mounting frame 221. When the caster telescopic mechanism 220 is in the support state, the caster 222 contacts the ground, and the caster 222 supports the treatment bed 200. When the treatment bed 200 is located at the second position and the caster telescopic mechanism 220 is in the support state, the mounting frame 221 and the mounting portion 211 can be locked and fixed by the locking mechanism 400 to fix the caster telescopic mechanism 220 in the support state. At the same time, the vertical limiting mechanism 500 cooperates with the mounting frame 221 to prevent the caster telescopic mechanism 220 from moving from the support state to the storage state.

[0056] See also Figures 1 to 10 In one embodiment, the breast screening device 10 further includes a locking mechanism 400, and the locking mechanism 400 is disposed on the mounting frame 221, and the locking mechanism 400 is used to lock and fix the mounting frame 221 and the mounting portion 211 when the caster retractable mechanism 220 is in the supporting state.

[0057] Specifically, when the caster telescopic mechanism 220 is in the supporting state, the caster telescopic mechanism 220 needs to be fixed so that the caster telescopic mechanism 220 can always be in the supporting state for the user to use. Therefore, a locking mechanism 400 is also provided, and the locking mechanism 400 can lock and fix the caster telescopic mechanism 220 so that the caster telescopic mechanism 220 can always be in the supporting state for the user to use. As for the form of the locking mechanism 400, it can be limited by the combination of the latch 310 and the slot, or by the combination of the buckle and the buckle groove, or by the absorption of a strong magnet. There are many ways of limiting, which are not listed here one by one. In the process of short-distance transportation of the breast screening device 10, the caster telescopic mechanism 220 can be retracted to the storage state to facilitate transportation. When the breast screening device 10 needs to be used for treatment, the caster telescopic mechanism 220 is stepped down to the supporting state for use.

[0058] See also Figures 1 to 10 In one embodiment, the locking mechanism 400 includes a locking portion 410, a limiting portion 420, a fixed shaft 430 and a foot pedal 440. The locking portion 410 is mounted on the mounting portion 211 and is provided with a locking groove 411. The limiting portion 420 is disposed on the mounting frame 221 and is provided with a locking head 421 adapted to the locking groove 411. The locking head 421 is located at the upper end of the limiting portion 420. The lower end of the limiting portion 420 is connected to the foot pedal 440. The limiting portion 420 and the foot pedal 440 are connected to the mounting frame 221 via the fixed shaft 430. When the caster telescopic mechanism 220 is in the supporting state, the locking head 421 is located in the locking groove 411.

[0059] Specifically, the locking portion 410 is plate-shaped and is arranged on the mounting portion 211. When the caster telescopic mechanism 220 is in the supporting state, the locking head 421 is inserted into the locking groove 411, and the mounting frame 221 no longer moves in the up-down direction, thereby limiting and fixing the caster telescopic mechanism 220, so that the caster telescopic mechanism 220 can maintain the supporting state. When the caster telescopic mechanism 220 needs to be moved from the storage state to the supporting state, it is only necessary to step on the foot pedal 440 downward, so that the mounting frame 221 can move downward, and until the locking head 421 is inserted into the locking groove 411, the caster telescopic mechanism 220 is in the supporting state. Conversely, when the caster telescopic mechanism 220 needs to be moved from the supporting state to the storage state, it is only necessary to lift the foot pedal 440 upward slightly, so that the locking head 421 can be disengaged from the locking groove 411, and then the mounting frame 221 moves upward until the caster telescopic mechanism 220 is in the storage position. It should be noted that when the caster telescopic mechanism 220 is moved from the supporting state to the storage state, it is necessary to ensure that the limiting rod 530 of the vertical limiting mechanism 500 is disengaged from the slot 2211 on the mounting frame 221 .

[0060] In one embodiment, the treatment bed 200 further includes a return spring, one end of which is connected to the bed frame 210, and the other end of which is connected to the bottom of the mounting frame 221, and the return spring is used to return the caster retractable mechanism 220 from the supporting state to the storage state.

[0061] Specifically, the number of the return springs can be set to be multiple, one end of the multiple return springs is connected to the bed frame 210, and the other end of the multiple return springs is connected to the bottom of the mounting frame 221. The multiple return springs can further enhance the return effect of the caster telescopic mechanism 220. When the caster telescopic mechanism 220 is in the supporting state, the return spring is in the extended state. When the lock head 421 is separated from the lock groove 411, the caster telescopic mechanism 220 is affected by the tension of the return spring and will be reset from the supporting state to the storage state. When the caster telescopic mechanism 220 is reset to the storage state, the return spring returns to the initial state.

[0062] See also Fig.14 and Fig.15 In one embodiment, the treatment bed 200 is provided with a first roller 224 close to the first end 111 and a second roller 225 close to the second end 112, the sliding platform 110 includes a sliding bracket 510 and a mounting plate 113, and the mounting plate 113 is mounted on the sliding bracket 510; when the treatment bed 200 is located at the first position, the first roller 224 abuts against the mounting plate 113, and the second roller 225 abuts against the mounting plate 113.

[0063] Specifically, the material of the sliding bracket 510 is supported by a hard material, which can be a metal, alloy or the like, and there is no specific limitation here. The mounting plate 113 is mounted on the sliding bracket 510. When the treatment bed 200 slides relative to the device body 100, the sliding platform 110 needs to provide support force to the treatment bed 200, and the mounting plate 113 can support the treatment bed 200. At the same time, the treatment bed 200 can slide relative to the device body 100, so it also has a device that allows the treatment bed 200 to slide relative to the device body 100, and the device is mounted on the mounting plate 113.

[0064] Since the treatment bed 200 adopts a caster retractable mechanism 220, the caster retractable mechanism 220 is installed at one end of the treatment bed 200 near the first end 111. Therefore, when the treatment bed 200 is located at the first position, the end of the treatment bed 200 provided with the caster retractable mechanism 220 will tilt downward due to its own weight, so that the stroke of the caster 222 of the treatment bed 200 is insufficient, resulting in the caster 222 failing to reach the specified position when stepped on, and failing to limit and fix. Therefore, the treatment bed 200 is provided with a first roller 224 near the first end 111. When the treatment bed 200 is located at the first position, the first roller 224 abuts against the mounting plate 113. The first roller 224 is mainly used to support the treatment bed 200 to prevent the treatment bed 200 from tilting and ensure that the stroke required for the caster 222 of the treatment bed 200 to step down to contact the ground is sufficient.

[0065] It is taken into consideration that when the treatment couch 200 is too heavy near the second end 112, the treatment couch 200 near the second end 112 will also tilt downward, so that the shell of the treatment couch 200 will touch the shell of the device body 100, so that the two shells are squeezed and damaged. In view of this, in order to avoid this situation, the treatment couch 200 is provided with a second roller 225 near the second end 112, and the second roller 225 abuts against the mounting plate 113 to prevent the treatment couch 200 from tilting downward near the second end 112.

[0066] Since the treatment bed 200 needs to be frequently pulled out and retracted during use, and in the process of retracting the treatment bed 200, there may be a height difference between the first roller 224 and the surface of the sliding platform 110, so that the treatment bed 200 cannot be retracted. At this time, the treatment bed 200 needs to be manually lifted slightly before it can be successfully retracted. In order to facilitate the use of the user, the first roller 224 and the second roller 225 are set as round rollers, and the material of the first roller 224 and the second roller 225 can be set as rubber material. When the treatment bed 200 is manually retracted, the first roller 224 and the second roller 225 slightly collide with the first end 111 of the sliding platform 110, and the first roller 224 and the second roller 225 can slide in directly to avoid the above problem.

[0067] Further, the number of the first roller 224 and the second roller 225 is set to two, and the two first rollers 224 and the second rollers 225 are respectively located on both sides of the width direction of the treatment bed 200. Specifically, the two first rollers 224 and the second rollers 225 can further increase the stability of the treatment bed 200.

[0068] See also Figures 1 to 13In one embodiment, the breast screening device 10 further includes a vertical limiting mechanism 500, which is installed on the bed frame 210; the vertical limiting mechanism 500 is used to prevent the caster retractable mechanism 220 from moving from the supporting state to the storage state when the treatment bed 200 is located in the second position.

[0069] Specifically, when the treatment bed 200 is located at the second position, the treatment bed 200 should be in use, and the caster retractable mechanism 220 is in the supporting state, supporting the treatment bed 200. In order to prevent the user from accidentally touching the caster retractable mechanism 220 to move from the supporting state to the storage state during the use of the breast screening device 10, a vertical limiting mechanism 500 is also provided. The limiting mechanism can limit and fix the caster retractable mechanism 220 when the treatment bed 200 is located at the second position and the caster retractable mechanism 220 is in the supporting state, so as to prevent the caster retractable mechanism 220 from moving from the supporting state to the storage state.

[0070] See also Figures 1 to 13 In one embodiment, the vertical limiting mechanism 500 includes a bracket 510, a second connecting member 520, a limiting rod 530, a second rotating shaft 540 and a reset rod 550. The bracket 510 is fixedly connected to the mounting portion 211. The second connecting member 520 is rotatably connected to the bracket 510 through the second rotating shaft 540, so that the second connecting member 520 can rotate; the limiting rod 530 is fixedly connected to the second connecting member 520, and the mounting frame 221 is provided with a card slot 2211. When the caster telescopic mechanism 220 is in the supporting state, the limiting rod 530 is located in the card slot 2211; the reset rod 550 is fixedly connected to the second connecting member 520 and is located at one end of the second rotating shaft 540 away from the limiting rod 530. When the treatment bed 200 is in the first position, the reset rod 550 abuts against the sliding platform 110, and the limiting rod 530 is disengaged from the card slot 2211.

[0071] Specifically, the bracket 510 is arranged in a C shape, the bracket 510 is fixedly mounted on the mounting portion 211, the second connecting member 520 is connected to the bracket 510 via the second rotating shaft 540, and the second connecting member 520 can rotate around the second rotating shaft 540 as the rotation center. When the caster telescopic mechanism 220 is in the supporting state, the second connecting member 520 rotates, driving the limiting rod 530 to rotate into the slot 2211, thereby limiting the caster telescopic mechanism 220. The second connecting member 520 is rotatably mounted on the mounting portion 211, and the limiting rod 530 is fixedly mounted on one end of the second connecting member 520 close to the slot 2211. When the caster telescopic mechanism 220 is in the storage state, the limiting rod 530 is located outside the slot 2211, and the caster telescopic mechanism 220 is not limited and fixed. When the caster telescopic mechanism 220 is in the supporting state, the limiting rod 530 is inserted into the slot 2211, so that the mounting frame 221 cannot move in the up and down directions, thereby preventing the caster telescopic mechanism 220 from being easily retracted from the supporting state to the storage state due to accidental touch by the user.

[0072] The reset rod 550 is used to disengage the limiting rod 530 from the slot 2211, so that the caster telescopic mechanism 220 can be moved from the supporting state to the storage state. The reset rod 550 and the limiting rod 530 are in opposite directions, and the reset rod 550 and the limiting rod 530 are respectively located at two ends of the second connecting member 520, and the second rotating shaft 540 is located between the reset rod 550 and the limiting rod 530. When the treatment bed 200 moves from the second position to the first position, the reset rod 550 will abut against the sliding platform 110. Since the sliding platform 110 is fixed, when the reset rod 550 abuts against the sliding platform 110, the reset rod 550 will be subjected to a reverse force, so that the reset rod 550 will move in the direction opposite to the moving direction of the treatment bed 200. At this time, the second connecting member 520 fixedly connected with the reset rod 550 will also rotate with the second rotating shaft 540 as the rotation center, so that the limiting rod 530 can be disengaged from the slot 2211. At this time, the caster telescopic mechanism 220 can be moved from the supporting state to the storage state to retract the casters 222 of the treatment bed 200.

[0073] See also Figures 1 to 13 Furthermore, the vertical limiting mechanism 500 also includes a second elastic member 560, one end of the second elastic member 560 is connected to the bed frame 210, and the other end of the second elastic member 560 is connected to the second connecting member 520, and the second elastic member 560 is used to push the second connecting member 520 to rotate around the second rotating shaft 540 so that the limiting rod 530 is inserted into the slot 2211.

[0074] Specifically, the second elastic member 560 is located between the second connecting member 520 and the mounting portion 211, and can increase elastic force for the vertical limiting mechanism 500 to ensure that the limiting rod 530 of the vertical limiting mechanism 500 can be rotated and inserted into the slot 2211 for limiting. The second elastic member 560 can be set as a spring or other elastic material, which is not specifically limited here. When the caster telescopic mechanism 220 is in the storage position, the limiting rod 530 is located outside the slot 2211 and below the slot 2211. Since the card slot 2211 is set on the mounting frame 221, when the caster telescopic mechanism 220 moves from the storage state to the supporting state, the card slot 2211 moves together with the downward movement of the mounting frame 221. When the caster telescopic mechanism 220 is in the supporting state, the limit rod 530 can be rotated and inserted into the card slot 2211 under the action of the elastic force of the second elastic member 560 to limit the mounting frame 221, thereby preventing the caster telescopic mechanism 220 from moving from the supporting state to the storage state due to accidental touch or misoperation by the user, thereby affecting the use.

[0075] See also Figures 1 to 15 In one embodiment, the treatment bed 200 further includes a bed body 230 , and the bed body 230 includes a first bed body 231 and a second bed body 232 , one end of the first bed body 231 is hinged to one end of the second bed body 232 , and the first bed body 231 is connected to the bed frame 210 .

[0076] Specifically, in order to reduce the lateral space of the breast screening device 10 occupied by the treatment bed 200, the treatment bed 200 can be set as a foldable treatment bed 200. The bed body 230 of the treatment bed 200 includes a first bed body 231 and a second bed body 232. The first bed body 231 can be fixedly connected to the bed frame 210 by screw connection or the like. One end of the first bed body 231 is hinged to one end of the second bed body 232 so that the second bed body 232 can be folded relative to the first bed body 231, so that the treatment bed 200 can be folded. When the breast screening device 10 is not in use, the bed body 230 of the treatment bed 200 can be folded and stowed to reduce the lateral space occupied by the breast screening device 10. At the same time, when the breast screening device 10 is transported over short distances, the bed body 230 of the treatment bed 200 can also be folded and stowed to facilitate short-distance transportation.

[0077] See also Figures 1 to 17 In one embodiment, the breast screening device 10 further includes a first slider 600 and a first slide rail 700 that slide with each other, one of the first slider 600 and the first slide rail 700 is installed on the bed frame 210, and the other is installed on the sliding platform 110, so that the treatment bed 200 slides between the first position and the second position.

[0078] Specifically, in this embodiment, the first slider 600 is installed on the sliding platform 110, the first slide rail 700 is installed on the bed frame 210, and the treatment bed 200 can slide along the length direction of the sliding platform 110. The sliding form of the treatment bed 200 adopts the form of a slide rail and a slider, and the first slider 600 and the first slide rail 700 are slidably matched to enable the treatment bed 200 to slide on the sliding platform 110. At the same time, the first slider 600 and the first slide rail 700 also play a role in limiting the sliding direction of the treatment bed 200.

[0079] See also Figures 1 to 17 In one embodiment, the treatment bed 200 further includes a second slider 240 and a second slide rail 250 that slide with each other, one of the second slider 240 and the second slide rail 250 is installed on the mounting portion 211, and the other is installed on the mounting frame 221, so that the caster telescopic mechanism 220 can move up and down relative to the bed frame 210.

[0080] Specifically, in this embodiment, the second slider 240 is fixedly connected to the mounting frame 221, the second slide rail 250 is fixedly mounted on the mounting portion 211, the mounting portion 211 extends in the up-down direction, and the caster telescopic mechanism 220 can slide in the up-down direction. The sliding form of the caster telescopic mechanism 220 adopts the form of a slider and a slide rail, the second slider 240 and the second slide rail 250 are slidably matched, so that the mounting frame 221 can slide in the up-down direction relative to the mounting portion 211, and at the same time, the second slider 240 and the second slide rail 250 also play a role in limiting the sliding direction of the mounting frame 221.
