[0012] Figure 2 It is a schematic diagram of the structure of the gun frame assembly. DETAILED DESCRIPTION

[0013] The utility model is described in detail below in conjunction with specific implementation methods:

[0014] like Figure 1 and Figure 2 The illustrated embodiment of a side screw locking gun body displacement mechanism for a car seat frame comprises a cross beam 1, a first guide rod 2, a first slider 21, a first bearing seat 3, a second slider 31, a second guide rod 32, a longitudinal beam 4 and a gun frame assembly, wherein the front and rear ends of the two second guide rods 32 are respectively fixedly mounted on the two cross beams 1, the two second guide rods 32 are fixedly mounted on the lower parts of the two cross beams 1 through connecting blocks, the second slider 31 is slidably mounted on the second guide rod 32, the first bearing seat 3 is fixedly mounted on the second slider 31, the left and right ends of the two first guide rods 2 are fixedly mounted on the first bearing seat 3, the first slider 21 is slidably mounted on the first guide rod 2, and the top of the longitudinal beam 4 is fixedly mounted on the first slider 21;

[0015] The gun rack assembly consists of a linear guide block 5, a linear slide rail 6, an L-shaped connecting block 7, a lifting ring 71, a spring scale 8, a locking sleeve 91, a locking screw gun body 9, a second bearing seat 94 and a traction rope. The second bearing seat 94 is set to an L-shaped structure. The guide block 5 is fixedly mounted on the longitudinal beam 4. The linear slide rail 6 is slidably mounted in the guide block 5 in an anti-slip manner. The L-shaped connecting block 7 and the second bearing seat 94 are respectively fixedly mounted at the middle and bottom positions of the linear slide rail 6. The lifting ring 71 is fixedly mounted on the L-shaped connecting block 7. The upper and lower ends of the traction rope are respectively fixedly connected to the first slider 21 and the spring scale 8 shell. The weighing hook lock buckle of the spring scale 8 is connected to the lifting ring 71. A rotating shaft 92 is fixedly mounted on the locking sleeve 91. The rotating shaft 92 is rotatably mounted in the second bearing seat 94. The locking screw gun body 9 is locked and fixedly mounted in the locking sleeve 91.

[0016] A knob plunger 93 is fixedly mounted on the second bearing seat 94, and a limiting hole 921 matching with the knob plunger 93 is arranged on the top of the rotating shaft 92. Two limiting holes 921 are symmetrically arranged about the central axis of the rotating shaft 92. When the combination of the locking sleeve 91 and the screw locking gun body 9 is rotated 180° to perform screw locking operations on the two sides of the automobile seat frame, the limiting pin of the knob plunger 93 is embedded in the limiting hole 921 for limiting, so as to prevent the combination of the locking sleeve 91 and the screw locking gun body 9 from rotating. After the knob plunger 93 is rotated to make its limiting pin disengage from the limiting hole 921, the limiting effect can be released.

[0017] A limit block 62 for limiting the upward movement limit position of the linear slide rail 6 is fixedly installed on the longitudinal beam 4. After the top of the linear slide rail 6 contacts the limit block 62, the upward movement limit position of the linear slide rail 6 is limited. In order to avoid noise generated by rigid collision between the linear slide rail 6 and the top of the limit block 62, an anti-collision rubber sleeve 61 is fixedly installed on the top of the linear slide rail 6 to play a role in buffering and noise reduction.

[0018] A screwdriver bit 10 is installed on the screw gun body 9. The operator holds the screw gun body 9 and can control the gun frame assembly to move left and right and front and back along the first guide rod 2 and the second guide rod 32. The operator pulls the screw gun body 9 downward to overcome the tension of the inner tension spring of the spring scale 8 (the tension of the inner tension spring of the spring scale 8 is only used to drive the combination of the locking sleeve 91 and the screw gun body 9 to reset upward, and is not used for the weighing function) to move downward. After the screw gun body 9 drives the screw driver bit 10 to rotate to assemble the relevant components on the right side of the automobile seat frame, the gun frame assembly is pulled to the left side of the automobile seat frame, and the combination of the locking sleeve 91, the screw gun body 9 and the rotating shaft 92 is rotated 180° relative to the second bearing seat 94, and then the screw gun body 9 drives the screw driver bit 10 to rotate to assemble the relevant components on the left side of the automobile seat frame.
