The limit frame 301 is identical to the inner structure of the sinking groove 7, and the second clamping stagnation assembly 11 is detachably arranged in the sinking groove 7, so that the effect that the connecting plate 5 can be quickly detached from the backrest when the sofa inner parts are replaced and overhauled is achieved, the time is saved, and the working efficiency of staff is improved. Meanwhile, when the connecting plate 5 is replaced, the second clamping stagnation assembly 11 can be taken down from the sinking groove 7 of the connecting plate 5, waste of the second clamping stagnation assembly 11 connected in the sinking groove 7 can be reduced, and cost is reduced. The first clamping component 6 and the second clamping component 11 are the same.

Specifically, the first clamping component 6 and the second clamping component 11 each include a clamping frame 1101 respectively arranged on the first screw 8 and the second screw 9, a second through groove 1102 is formed in one side of the clamping frame 1101, a first sliding groove 1103 is symmetrically formed in the clamping frame 1101, a second sliding groove 1104 is formed in the inner wall of the first sliding groove 1103, a sliding block 1105 is slidably arranged in the first sliding groove 1103, the outer side end of the sliding block 1105 is provided with a chamfer, lugs 1106 are symmetrically arranged on the sliding block 1105, the lugs 1106 are slidably arranged in the second sliding groove 1104, the lugs 1106 can be limited by the second sliding groove 1104, and sealing plates 1107 are symmetrically arranged on the second through groove 1102 and are connected with the clamping frame 1101 through screws. A spring 1109 is arranged in the first chute 1103, one end of the spring 1109 is connected with the sealing plate 1107, the other end is connected with the sliding block 1105, the bottom end of the sliding block 1105 is also provided with a sliding rod 1108, the spring 1109 is sleeved on the sliding rod 1108, the sliding rod 1108 penetrates the sealing plate 1107 correspondingly arranged and is arranged in a sliding manner in the sealing plate 1107, and the free end of the sliding rod 1108 is provided with a force application piece 1110.

When the first clamping component 6 is required to be connected with the corresponding limiting component 3, the clamping frame 1101 on the first clamping component 6 can be inserted into the limiting frame 301 of the limiting component 3, after the sliding blocks 1105 on the clamping frame 1101 are contacted with the inclined blocks 303 on the limiting frame 301, the sliding blocks 1105 on the clamping frame 1101 are continuously inserted into the limiting frame 301, at the moment, the two sliding blocks 1105 on the clamping frame 1101 start to slide towards opposite directions under the action of the two inclined blocks 303 in the limiting frame 301, the sliding blocks 1105 compress the springs 1109 while sliding, the sliding rods 1108 and the force applying pieces 1110 also move along the sliding blocks 1105, the tail ends of the sliding blocks 1105 of the clamping frame 1101 are staggered with the tail ends of the inclined blocks 303 of the limiting frame 301, and the sliding blocks, the sliding rods 1108 and the force applying pieces 1110 which are correspondingly arranged on the sliding blocks 1109 are lifted towards opposite sides, so that the sliding blocks 1105 and the inclined blocks 303 are limited.

When the first clamping component 6 needs to be detached from the limiting component 3, the two force application pieces 1110 on the same clamping frame 1101 can be manually pressed and moved towards the center, each sliding block 1105 on the same clamping frame 1101 can be fixed towards the center under the action of the sliding rod 1108, the sliding block 1105 is separated from the limiting oblique block 303, and then the clamping frame 1101 is pulled out from the limiting frame 301 to complete the detachment, so that the operation is simple and the use is convenient. Meanwhile, the first clamping stagnation component 6 and the corresponding limiting component 3 can be connected quickly, and the second clamping stagnation component 11 and the corresponding sinking groove 7 of the connecting plate 5 can be connected quickly, so that time and labor are saved, and the operation is simple.

Similarly, the connection mode of the second clamping stagnation group and the sinking grooves 7 at two ends of the connecting plate 5 is the same as the disassembly and assembly mode of the first clamping stagnation component 6 and the limiting component 3, and will not be described herein. The biasing member 1110 may be a disc or a bar, and is not limited thereto.
