DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0019] Depend on Figure 1-5 The utility model comprises a first chassis 1 and a second chassis 2, which are arranged side by side on the left and right sides, and connectors 3 are arranged on both sides of the butt ends of the first chassis 1 and the second chassis 2, and a first frame 4 whose size is adapted to the first chassis 1 is fixedly installed on the top, a second frame 6 is fixedly installed on the left half of the top of the second chassis 2, and a third frame 7 is arranged on the right half of the top of the second chassis 2, and the size of the second frame 6 and the third frame 7 after being assembled is the same as the size of the first frame 4, and connectors 8 rotatably connected to the two ends of the second frame 6 are fixedly installed on both ends of the third frame 7, and recessed areas 5 are provided on the right halves of both sides of the second chassis 2, and mobile blocks 9 are movably sleeved in the two recessed areas 5 on the second chassis 2, and first fixing members 10 are fixedly installed on the tops of the two mobile blocks 9, and second fixing members 11 are fixedly installed on both sides of the bottom of the third frame 7, and connecting rods 12 are movably connected between the two second fixing members 11 and the first fixing members 10 on the corresponding mobile blocks 9.
[0020] At the same time, both ends of the connecting rod 12 can rotate around the first fixing member 10 and the second fixing member 11 respectively. When the third frame 7 is in a horizontal state, the connecting rod 12 between the first fixing member 10 and the second fixing member 11 is also in a horizontal state.
[0021] In addition, the movable block 9 includes a lower block 91 and an upper block 92. The lower block 91 is movably sleeved in the lower half of the recessed area 5, and the upper block 92 is movably sleeved in the upper half of the recessed area 5. A tooth groove 13 is provided at the top of the recessed area 5, and a limit block 14 is fixedly installed at the top of the inner wall of the upper block 92. The bottom of the limit block 14 is provided with teeth that can engage with the tooth groove 13. After adjusting the position of the movable block 9 in the recessed area 5, the connecting rod 12 is pulled up to move the upper block 92 up, so that the limit block 14 on the inner wall of the upper block 92 will be separated from the tooth groove 13, and then the position of the upper block 92 and the lower block 91 can be adjusted. After the adjustment, the limit block 14 on the inner wall of the upper block 92 is easy to automatically engage in the tooth groove 13 under the action of gravity and pressure, thereby completing the position fixing of the movable block 9.
[0022] Moreover, when the inner wall of the upper clamping block 92 contacts the outer wall of the recessed area 5, the bottom end of the limit block 14 is engaged in the tooth groove 13 at the top of the recessed area 5, and the third frame 7 applies pressure to the upper clamping block 92 through the connecting rod 12, so that the limit block 14 on the inner wall of the upper clamping block 92 is stably engaged in the tooth groove 13.
[0023] In addition, through holes 16 are provided at both ends of both sides of the top of the lower clamping block 91, and inner grooves 15 are provided at the bottoms of the four through holes 16. Insert rods 17 are fixedly installed at both ends of both sides of the bottom of the upper clamping block 92. The four insert rods 17 are movably inserted in the corresponding through holes 16 respectively, and the bottom ends of the four insert rods 17 extend into the inner grooves 15, and limiting plates 18 are fixedly installed at the bottom ends of the four insert rods 17. Springs 19 sleeved on the insert rods 17 are fixedly connected between the tops of the four limiting plates 18 and the tops of the corresponding inner walls of the inner grooves 15. Through the insertion of the four insert rods 17 into the inner grooves 15, the upper clamping block 92 and the lower clamping block 91 can be stably connected together, and the upper clamping block 92 is more stable when moving.
[0024] In addition, the sizes of the inner groove 15 and the limiting plate 18 are both larger than the size of the through hole 16 , so that the limiting plate 18 can squeeze the spring 19 when moving upward in the inner groove 15 , and the limiting plate 18 cannot be separated from the inner groove 15 .
[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
