Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic panel installation, and specifically refers to a photovoltaic panel splicing device for photovoltaic power generation. Background Art

[0002] During the construction of photovoltaic power generation equipment, photovoltaic panels need to be assembled onto the bracket one by one. In the prior art, there are many problems in the photovoltaic panel splicing technology:

[0003] Due to the limitation of the installation site of the photovoltaic panel, the splicing and installation of photovoltaic panels mostly rely on manual labor. Construction workers lift the photovoltaic panels to the area to be installed one by one, and then manually fasten and install the photovoltaic panels. This installation method is time-consuming and laborious and has low efficiency;

[0004] In order to prevent water seepage at the bottom of the photovoltaic panel and prevent the photovoltaic panel from being squeezed and broken due to the thermal expansion and contraction effect, a certain gap needs to be set between adjacent photovoltaic panels, and then a sealing strip is filled at the gap. The construction of the sealing strip also needs to rely on manual labor, and the efficiency is also low;

[0005] The precision of manually installing photovoltaic panels is not high. The photovoltaic panels on the same bracket are prone to height and inclination deviations, resulting in stress concentration or water seepage between adjacent photovoltaic panels, affecting the power generation efficiency of the photovoltaic panels. Summary of the Invention

[0006] In view of the above technical problems, the invention provides a photovoltaic panel splicing device for photovoltaic power generation. The detachable splicing sliding frame is used to reciprocally convey and install the photovoltaic panels on the bracket. The movement state of the rubber strip stuffing device is automatically controlled through the mutual extrusion of the photovoltaic panels during the conveying process, so that the photovoltaic panels are automatically dropped onto the bracket, and the photovoltaic panels are automatically locked by relying on the extrusion of the photovoltaic panels on the self-locking pressing block. The photovoltaic panel assembly process not only relies on the equipment, but also cleverly utilizes the movement and extrusion of the photovoltaic panels. Moreover, the photovoltaic panel locking process can be achieved without relying on manual labor or other machinery, significantly improving the assembly efficiency of the photovoltaic panels, and quickly stuffing the sealing strip through the rubber strip stuffing device, effectively preventing water seepage at the seams of the photovoltaic panels.

[0007] The technical solution adopted by the invention is as follows:

[0008] A photovoltaic panel splicing device for photovoltaic power generation, comprising a bracket, a splicing carriage and a self-locking pressing block. Two fixed crossbars are fixedly connected to the bracket by bolts. Pressing block grooves are formed in the fixed crossbars. Translation tracks are respectively fixedly connected to the outer walls of the two fixed crossbars. The splicing carriage is detachably slidably arranged on the translation tracks. The self-locking pressing block is detachably slidably clamped in the pressing block grooves on the fixed crossbars. The splicing carriage is used for conveying the photovoltaic panels to be installed and fixing the photovoltaic panels to be installed. The bracket is used for supporting the installed photovoltaic panels. The self-locking pressing block is an installation consumable. The self-locking pressing block is placed between adjacent photovoltaic panels to tightly lock the edges of adjacent photovoltaic panels. The splicing carriage is composed of a main frame, a sub-frame and a rubber strip stuffing device. The sub-frames are symmetrically distributed and fixedly arranged on the lower walls at both ends of the main frame. The two sub-frames are respectively slidably arranged on the two translation tracks. Crossbeams are respectively fixedly arranged at both ends of the main frame. The rubber strip stuffing device is slidably sleeved on the crossbeams at both ends of the main frame. Two sets of feeding push rods are fixedly arranged on the lower wall of one side frame of the main frame. The two sets of feeding push rods respectively correspond to the pressing block grooves on the two fixed crossbars. When the sub-frame moves on the translation track, the feeding push rods move into the pressing block grooves. The feeding push rods are used for pushing the self-locking pressing block to the side of the photovoltaic panel to be installed. An extrusion blanking block is slidably arranged on the sub-frame. The extrusion blanking block is used for supporting the photovoltaic panel to be installed to prevent the photovoltaic panel to be installed from rubbing against the fixed crossbar during the conveying process.

[0009] The rubber strip stuffing device comprises a slide bar, a guide plate, a slider and a stuffing rod. Both ends of the slide bar are respectively slidably sleeved on the crossbeams at both ends of the main frame. The guide plates are symmetrically distributed and fixedly arranged on the upper wall of the slide bar. The slider is slidably clamped on the guide plate. The stuffing rod is slidably penetrated through the slider. A rubber strip stuffing groove is formed in the middle of the slide bar. The rubber strip stuffing groove is located between the two guide plates. Support rubber strips are respectively arranged on two opposite side walls in the rubber strip stuffing groove. The sliding axis direction of the stuffing rod points to the rubber strip stuffing groove. Guide grooves are formed through the side walls of the guide plates. The guide grooves are composed of a flat groove and two inclined grooves. The two inclined grooves are respectively smoothly connected to both ends of the flat groove. A guide button is fixedly arranged on the side wall of the stuffing rod. The guide button is movably arranged in the guide groove. A rolling wheel is rotatably arranged at the lower end of the stuffing rod. A spring is connected between the outer side wall of the slide bar and the inner side wall of the main frame. Push pieces are respectively hinged at both ends of the lower edge of one side wall in the rubber strip stuffing groove. The lower parts of the push pieces extend out of the rubber strip stuffing groove and extend below the upper surface height of the photovoltaic panel. The upper parts of the push pieces are located in the rubber strip stuffing groove.

[0010] As a preferred solution of the present invention, a stuffing electric push rod is fixedly arranged at the upper end of the slide bar. The telescopic direction of the stuffing electric push rod is consistent with the direction in which the slider slides along the guide plate. The output end of the stuffing electric push rod is fixedly connected to the side wall of the slider.

[0011] As another alternative solution of the present invention, a pull rope is connected to the slider, which is convenient for construction workers to directly pull the slider to slide along the guide plate.

[0012] One side wall of the sliding bar close to the extrusion blanking block is fixedly provided with an extrusion rod. The extrusion rod is horizontally slidably arranged on the upper wall of the sub-frame. The extrusion rod and the extrusion blanking block are drivingly arranged. Specifically, a convex rod is arranged on one side of the extrusion rod close to the extrusion blanking block. An inclined linkage groove is formed on one side wall of the extrusion blanking block close to the extrusion rod. The convex rod is movably arranged in the inclined linkage groove. When the side of the installed photovoltaic panel touches the extrusion rod, the extrusion blanking block automatically drops the photovoltaic panel to be installed onto the fixed cross bar.

[0013] The self-locking pressing block includes a base, a barbed anchor rod and a double-sided pressing block. The base is movably clamped into the pressing block groove. A pressing hole is formed in the middle of the upper wall of the base. The barbed anchor rod is vertically slidably arranged in the pressing hole on the upper wall of the base. The double-sided pressing block is fixedly arranged on the barbed anchor rod. Barbs are fixedly arranged on the circumferential outer wall of the barbed anchor rod. The upper end of the barbed anchor rod is arranged inside the double-sided pressing block. Transmission rods are symmetrically distributed and slidably penetrate through the side walls of the double-sided pressing block. The upper end of the barbed anchor rod and the end of the transmission rod close to the barbed anchor rod are both inclined surfaces and are cooperatively arranged. When the transmission rod is subjected to an extrusion force, the barbed anchor rod is pressed into the pressing hole on the base through the action of the inclined surface. Due to the arrangement of the barbs, the barbed anchor rod can only enter the pressing hole and cannot be pulled out. The double-sided pressing block moves downward following the barbed anchor rod, thereby realizing the function of tightly locking the photovoltaic panels on both sides of it.

[0014] In order to enable the splicing sliding frame to reciprocate on the support to transport the photovoltaic panel to be installed, a moving motor is fixedly arranged on the inner side wall of the sub-frame. Rollers are rotatably arranged in an array on the lower wall of the sub-frame. The rollers respectively roll in the translation tracks. The output shaft of the moving motor is coaxially and fixedly connected to one of the rollers.

[0015] The beneficial effects obtained by the present invention are as follows:

[0016] (1) The present invention uses a detachable splicing sliding frame to reciprocally transport and install photovoltaic panels on the support. The movement state of the rubber strip stuffing device is automatically controlled through the mutual extrusion action during the transportation of the photovoltaic panels, thereby automatically dropping the photovoltaic panels onto the support. And relying on the extrusion action of the photovoltaic panels on the self-locking pressing block to realize the automatic locking of the photovoltaic panels. The process of assembling the photovoltaic panels not only depends on the equipment itself, but also cleverly utilizes the movement and extrusion action of the photovoltaic panels. And the locking process of the photovoltaic panels can be realized without relying on manual labor or other machinery, significantly improving the assembly efficiency of the photovoltaic panels. And the rubber strip stuffing device quickly stuffs the sealing rubber strip, effectively preventing the phenomenon of water leakage at the seams of the photovoltaic panels;

[0017] (2) The push piece in the rubber strip stuffing device touches the photovoltaic panel, so that the whole rubber strip stuffing device reaches the seam of the photovoltaic panel. By means of the relative movement between the main frame and the rubber strip stuffing device, the lifting control of the extrusion blanking block is realized, thereby automatically dropping the photovoltaic panel to be installed onto the fixed cross bar;

[0018] (3) The upper end of the barbed anchor rod in the self-locking pressure block and the end of the force transmission rod close to the barbed anchor rod are both inclined and matched with each other. When the force transmission rod is squeezed, the barbed anchor rod is pressed into the pressing hole on the base through the action of the inclined surface. Due to the setting of the barbs, the barbed anchor rod can only enter the pressing hole and cannot be pulled out. The double-sided pressure block moves downward with the barbed anchor rod, thereby realizing the compression and locking function of the photovoltaic panels on both sides thereof;

[0019] (4) The inner wall of the rubber strip filling groove limits the rotation range of the push piece, ensuring that when the slide moves toward the installed photovoltaic panel, the push piece can produce a contact and resistance effect with the photovoltaic panel, so that the rubber strip filling device is stable at the joint of the photovoltaic panel, and when the splicing slide returns, the push piece can rotate and pass over the photovoltaic panel;

[0020] (5) The feeding push rod can automatically push the new self-locking block to the installation station, which is convenient for self-locking the photovoltaic panel to be installed next time;

[0021] (6) The slider, the filling rod and the guide plate in the rubber strip filling device are linked together through a special guide groove. When the slider moves along the guide plate, the sealing strip is automatically pressed and filled. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation manners

[0037] Embodiment 1: Please refer to Figures 1-8, this embodiment provides a photovoltaic panel splicing device for photovoltaic power generation, which includes a bracket 1, a splicing carriage 2 and a self-locking pressure block 3. Two fixed crossbars 11 are fixedly connected to the bracket 1 by bolts. A pressure block groove 111 is formed in the fixed crossbar 11. Translation tracks 112 are fixedly connected to the outer walls of the two fixed crossbars 11 respectively. The splicing carriage 2 is detachably slidably arranged on the translation tracks 112. The self-locking pressure block 3 is detachably slidably clamped in the pressure block groove 111 on the fixed crossbar 11. The splicing carriage 2 is used to convey the photovoltaic panel 4 to be installed and fix the photovoltaic panel 4 to be installed. The bracket 1 is used to support the installed photovoltaic panel 4. The self-locking pressure block 3 is an installation consumable. The self-locking pressure block 3 is placed between adjacent photovoltaic panels 4 to tightly lock the edges of adjacent photovoltaic panels 4. The splicing carriage 2 is composed of a main frame 21, a sub-frame 22 and a rubber strip stuffing device 23. The sub-frames 22 are symmetrically distributed and fixedly arranged on the lower walls at both ends of the main frame 21. The two sub-frames 22 are respectively slidably arranged on the two translation tracks 112. Cross beams 211 are fixedly arranged at both ends of the main frame 21. The rubber strip stuffing device 23 is slidably sleeved on the cross beams 211 at both ends of the main frame 21. The rubber strip stuffing device 23 stuffs a sealing rubber strip 5 between two adjacent photovoltaic panels 4. Two sets of feeding push rods 212 are fixedly arranged on the lower wall of one side frame of the main frame 21. The two sets of feeding push rods 212 correspond to the pressure block grooves 111 on the two fixed crossbars 11 respectively. When the sub-frame 22 moves on the translation track 112, the feeding push rod 212 moves into the pressure block groove 111. The feeding push rod 212 is used to push the self-locking pressure block 3 to the side of the photovoltaic panel 4 to be installed. An extrusion blanking block 221 is slidably arranged on the sub-frame 22. The extrusion blanking block 221 is used to support the photovoltaic panel 4 to be installed to prevent the photovoltaic panel 4 to be installed from rubbing against the fixed crossbar 11 during the conveying process.

[0038] As Figure 1 , Figures 4-9As shown in the figure, the rubber strip stuffing device 23 includes a slide bar 231, a guide plate 232, a slider 233 and a stuffing rod 234. The two ends of the slide bar 231 are respectively sleeved on the cross beams 211 at the two ends of the main frame 21 in a sliding manner. The guide plates 232 are symmetrically distributed and fixedly arranged on the upper wall of the slide bar 231. The slider 233 is slidably clamped on the guide plate 232. The stuffing rod 234 is slidably penetrated through the slider 233. A rubber strip stuffing groove 2311 is formed in the middle of the slide bar 231. The rubber strip stuffing groove 2311 is located between the two guide plates 232. Support rubber strips 2312 are respectively arranged on the two opposite side walls in the rubber strip stuffing groove 2311. The sliding axis direction of the stuffing rod 234 points to the rubber strip stuffing groove 2311. A guide groove 2321 is penetrated through the side wall of the guide plate 232. The guide groove 2321 is composed of a flat groove 2322 and two inclined grooves 2323. The two inclined grooves 2323 are respectively smoothly connected to both ends of the flat groove 2322. A guide button 2341 is fixedly arranged on the side wall of the stuffing rod 234. The guide button 2341 is movably arranged in the guide groove 2321. A rolling wheel 2342 is rotatably arranged at the lower end of the stuffing rod 234. A spring 235 is connected between the outer side wall of the slide bar 231 and the inner side wall of the main frame 21. The spring 235 is located Figure 1 on the right inner wall of the main frame 21 in Figure 8 For example, the push piece 2313 is located on the right inner wall of the rubber strip stuffing groove 2311. The lower part of the push piece 2313 extends out of the rubber strip stuffing groove 2311 and extends below the upper surface height of the photovoltaic panel 4. The upper part of the push piece 2313 is located in the rubber strip stuffing groove 2311. The inner side wall of the rubber strip stuffing groove 2311 limits the rotation range of the push piece 2313 to ensure that the slide bar 231 can be driven by the push piece 2313 in a single direction and ensure that the push piece 2313 can cross the photovoltaic panel 4 in a single direction;

[0039] In order to facilitate stuffing the sealing rubber strip 5, a stuffing electric push rod 2314 is fixedly arranged at the upper end of the slide bar 231. The telescopic direction of the stuffing electric push rod 2314 is the same as the sliding direction of the slider 233 along the guide plate 232. The output end of the stuffing electric push rod 2314 is fixedly connected to the side wall of the slider 233;

[0040] An extrusion rod 2315 is fixedly arranged on the side wall of the slide bar 231 close to the extrusion blanking block 221. The extrusion rod 2315 is horizontally slidably arranged on the upper wall of the sub-frame 22. The extrusion rod 2315 and the extrusion blanking block 221 are transmissionally arranged. Specifically, a convex rod 2316 is arranged on the side of the extrusion rod 2315 close to the extrusion blanking block 221. An inclined linkage groove 2211 is formed in the side wall of the extrusion blanking block 221 close to the extrusion rod 2315. The convex rod 2316 is movably arranged in the inclined linkage groove 2211. When the side of the already installed photovoltaic panel 4 touches the extrusion rod 2315, the transmission effect of the convex rod 2316 and the inclined linkage groove 2211 causes the extrusion blanking block 221 to descend and automatically drop the photovoltaic panel 4 to be installed onto the fixed cross bar 11.

[0041] As Figure 1 , Figure 10 shown, the self-locking pressing block 3 includes a base 31, barbed anchor bolts 32 and a bilateral pressing block 33. The base 31 is movably clamped into the pressing block groove 111. A pressing hole 311 is formed in the middle of the upper wall of the base 31. The barbed anchor bolts 32 are vertically slidably arranged in the pressing hole 311 on the upper wall of the base 31. The bilateral pressing block 33 is fixedly arranged on the barbed anchor bolts 32. Barbs 321 are fixedly arranged on the circumferential outer wall of the barbed anchor bolts 32. The upper ends of the barbed anchor bolts 32 are arranged inside the bilateral pressing block 33. Transmission rods 331 are symmetrically distributed and slidably penetrate through the side walls of the bilateral pressing block 33. The upper ends of the barbed anchor bolts 32 and the ends of the transmission rods 331 close to the barbed anchor bolts 32 are both inclined surfaces and are arranged in cooperation with each other. When the transmission rods 331 are subjected to extrusion, the barbed anchor bolts 32 are pressed into the pressing holes 311 on the base 31 through the action of the inclined surfaces. Due to the arrangement of the barbs 321, the barbed anchor bolts 32 can only enter the pressing holes 311 and cannot be pulled out. The bilateral pressing block 33 moves downward along with the barbed anchor bolts 32, thereby realizing the function of tightly locking the photovoltaic panels 4 on both sides thereof.

[0042] As Figure 1 , Figure 11 shown, in order to enable the splicing carriage 2 to reciprocate on the bracket 1 to transport the photovoltaic panels 4 to be installed, a moving motor 222 is fixedly arranged on the inner side wall of the sub-frame 22. Roller wheels 223 are rotatably arranged in an array on the lower wall of the sub-frame 22. The roller wheels 223 respectively roll in the translation tracks 112. The output shaft of the moving motor 222 is coaxially and fixedly connected to one of the roller wheels 223.

[0043] As Figures 1-6 shown, an extrusion baffle 224 is fixedly arranged on the upper wall of the sub-frame 22. A pressure sensor 225 is fixedly arranged on one side wall of the extrusion baffle 224 close to the rubber strip stuffing device 23. The extrusion baffle 224 is used to push the photovoltaic panel 4 to be installed to move and squeeze against the side wall of the installed photovoltaic panel 4. A single-chip microcomputer (not shown in the figure) is attached to the side wall of the main frame 21. The model of the single-chip microcomputer is STM32F103C8T6. The pressure sensor 225, the moving motor 222 and the stuffing electric push rod 2314 are respectively electrically connected to the single-chip microcomputer.

[0044] When this embodiment is specifically used, the operation process is as follows:

[0045] First, install the bracket 1. After the bracket 1 is installed, start installing the photovoltaic panels 4. The outermost end ( Figure 1The photovoltaic panel 4 at the rightmost end is installed manually. A self-locking press block 3 is inserted into each of the two press block grooves 111 and pushed to the photovoltaic panel 4 at the farthest end. Then, the construction worker places the splicing carriage 2 on the bracket 1, so that some rollers 223 on the two sub-frames 22 roll in the two translation tracks 112 respectively, and the nearest end of the splicing carriage 2 does not enter the bracket 1 for the time being (that is, the feeding push rod 212 does not enter the press block groove 111 for the time being), which is convenient for inserting a new pair of self-locking press blocks 3.

[0046] In the initial state, due to the action of the spring 235, the slide bar 231 is close to the inner side wall of the main frame 21 (the side close to the photovoltaic panel 4 at the farthest end, that is, Figure 1 the position in ), the slide bar 231 drives the extrusion rod 2315, so that the extrusion rod 2315 and the extrusion blanking block 221 are in Figure 9 the state in, that is, the extrusion blanking block 221 extends out of the upper wall of the sub-frame 22. In order to facilitate filling the sealing strip, in the initial state, the filling electric push rod 2314 is in a contracted state.

[0047] The construction worker places the photovoltaic panel 4 to be installed in the splicing carriage 2. The photovoltaic panel 4 to be installed is located between the slide bar 231 and the extrusion baffle 224. The two extrusion blanking blocks 221 support the photovoltaic panel 4 to be installed. A sealing strip 5 is filled into the rubber strip filling groove 2311. The sealing strip 5 is supported by the support rubber strip 2312. A self-locking press block 3 is inserted into each of the two press block grooves 111 from the extrusion blanking block 221. Then, the photovoltaic panel 4 to be installed is conveyed. The single-chip microcomputer controls the operation of the moving motor 222. The moving motor 222 drives the rollers 223 to rotate, so that the whole splicing carriage 2 moves on the bracket 1. The splicing carriage 2 drives the photovoltaic panel 4 to be installed to move towards the photovoltaic panel 4 at the farthest end. The feeding push rod 212 enters the press block groove 111 to push the self-locking press block 3 to move. When the push piece 2313 touches the outer side wall of the photovoltaic panel 4 at the farthest end, due to the blocking effect of the push piece 2313, the slide bar 231 cannot continue to move with the splicing carriage 2. The main frame 21 and the sub-frame 22 continue to move, and the spring 235 is stretched. At this time, the extrusion rod 2315 and the extrusion blanking block 221 generate relative movement, that is, the sub-frame 22 drives the extrusion blanking block 221 to move to the right (taking Figure 9 as an example), the extrusion rod 2315 cannot move due to the limitation of the slide bar 231. Then, due to the inclined guiding action of the convex rod 2316 and the inclined linkage groove 2211, the extrusion blanking block 221 moves downward, so as to drop the photovoltaic panel 4 to be installed onto the sub-frame 22. When the right side of the photovoltaic panel 4 to be installed (taking Figure 1For example), when it touches the self-locking pressing block 3 placed at the beginning (at the photovoltaic panel 4 at the farthest end), the photovoltaic panel 4 to be installed is blocked, and the main frame 21 and the sub-frame 22 continue to move until the extrusion baffle 224 touches the left side of the photovoltaic panel 4 to be installed. The extrusion baffle 224 extrudes the photovoltaic panel 4 to be installed. The photovoltaic panel 4 to be installed and the photovoltaic panel 4 at the farthest end extrude the self-locking pressing block 3 placed at the beginning. The force transmission rod 331 is extruded, and due to the action of the inclined plane, the barbed anchor rod 32 is pressed into the pressing hole 311 on the base 31. Due to the setting of the barbs 321, the barbed anchor rod 32 can only enter the pressing hole 311 and cannot be pulled out. The double-sided pressing block 33 moves downward following the barbed anchor rod 32, thereby achieving the pressing and locking effect on the photovoltaic panels 4 to be installed on both sides and the photovoltaic panel 4 at the farthest end.

[0048] After the photovoltaic panel 4 to be installed is locked, a new self-locking pressing block 3 pushed by the feeding push rod 212 reaches the left side of this photovoltaic panel 4, preparing to install and lock the next photovoltaic panel 4.

[0049] When the extrusion force of the extrusion baffle 224 on the photovoltaic panel 4 is monitored by the pressure sensor 225, this extrusion force is mainly to ensure the locking effect of the self-locking pressing block 3. After the pressure reaches the requirement, the single-chip microcomputer controls the moving motor 222 to stop running, and makes the stuffing electric push rod 2314 perform a telescopic movement. The elongation of the stuffing electric push rod 2314 drives the slider 233 to slide along the guide plate 232, and the guide button 2341 moves along the guide groove 2321. When the guide button 2341 enters the upper inclined groove 2323, the stuffing rod 234 moves downward relative to the slider 233 under the action of the guide button 2341 and the inclined groove 2323, causing the rolling wheel 2342 to descend and press the sealing strip 5, so that the sealing strip 5 is pressed into the joint of the two photovoltaic panels 4. After the guide button 2341 enters the flat groove 2322, the rolling wheel 2342 continuously presses the sealing strip 5 until the guide button 2341 reaches the lower inclined groove 2323, and the pressing ends. The stuffing electric push rod 2314 contracts, causing the slider 233 to return, and pressing the sealing strip 5 again during the return process.

[0050] After the sealing strip 5 is stuffed, the single-chip microcomputer controls the moving motor 222 to run in the reverse direction, causing the splicing carriage 2 to return as a whole. The self-locking pressing block 3 pushed by the feeding push rod 212 does not return, and the pushing piece 2313 can rotate and cross the installed photovoltaic panel 4.

[0051] After all the photovoltaic panels 4 on this bracket 1 are installed, the construction personnel take out the splicing carriage 2 and move it to the next bracket 1 for subsequent installation.

[0052] Embodiment 2: As Figure 12As shown in the figure, the difference between this embodiment and the first embodiment is that in the rubber strip stuffing device 23 of this embodiment, the stuffing electric push rod 2314 is no longer provided. Instead, a pulling rope 2331 is connected to the two opposite outer walls of the slider 233. The length of the pulling rope 2331 exceeds the length of the sliding strip 231. The construction worker can directly pull the pulling rope 2331 to make the slider 233 slide along the guide plate 232.

[0053] The present invention and its embodiments have been described above. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
