However, the spring is an elastic pushing component, which cannot implement rigid top clamping and fixing of the workpiece, and cannot stably clamp and maintain the clamping and fixing mechanism. As a result, when the clamping and fixing mechanism is accidentally collided during use, the clamping and fixing mechanism is prone to loosening and displacement, causing the workpiece to loosen and fall, resulting in the clamping and fixing mechanism being unable to take into account both the convenience of tightening and loosening operation and the stability of clamping and fixing. Utility Model Content

[0042] Please refer to Figures 1 to 6 ;

[0043] Embodiment 1:

[0044] The present utility model provides a flip mechanism with adjustable levelness, including a support frame 1, a positioning wheel 101, a strip-shaped clamping plate 102, a connecting rod 1021, a long strip card slot 1022, a positioning short shaft 103, an I-shaped base 2, an upright support rod 201, an insertion positioning part 202, an L-shaped drive rod 3, a sliding sleeve 301, a U-shaped vertical support frame 3011, an insert block 3012, a push shaft 302, a positioning sleeve 303, a positioning rack 4, and a C-shaped sliding frame 401. The support frame 1 and the I-shaped base 2 are integrally composed of two longitudinal support side rods on the left and right and two front and rear transverse positioning axes symmetrically welded;

[0045] Among them, two longitudinally arranged strip-shaped clamping plates 102 are symmetrically installed on the transverse positioning axis by spring top push and slide, and the two strip-shaped clamping plates 102 are used to clamp and fix the circuit board; a positioning short shaft 103 that supports backward is welded at the middle position of the front transverse positioning axis; two connecting rods 1021 are symmetrically and rotatably connected to the rear ends of the two strip-shaped clamping plates 102;

[0046] An L-shaped driving rod 3 is slidably installed on the right longitudinal brace side rod, the head end of the cross brace section of the L-shaped driving rod 3 is slidably matched with the positioning short shaft 103, and the head ends of the two connecting rods 1021 are rotatably connected with the head ends of the cross brace sections of the L-shaped driving rod 3. The two connecting rods 1021, the L-shaped driving rod 3 and the two strip clamps 102 are connected together to form two crank slider mechanisms. Through these two mechanisms, the L-shaped driving rod 3 can be pushed and driven to push the two strip clamps 102. The clamping plates 102 slide away from each other to release the circuit board. After the L-shaped driving rod 3 is released, the spring on the transverse positioning shaft can rebound and push to drive the two strip clamping plates 102 to slide closer to each other to clamp and fix the circuit board. Then, the clamping and fixing mechanism can be driven to loosen and tighten the circuit board by simply sliding the L-shaped driving rod 3 backward and releasing the L-shaped driving rod 3. The operation is convenient and quick. The two crank slider mechanisms are actually mechanisms for clamping and fixing the circuit board.

The insert block 3012 can be plugged into and positioned the L-shaped driving rod 3, and auxiliary fixation is implemented on the two strip clamps 102, so that the two strip clamps 102 and the entire clamping and fixing mechanism can stably clamp and hold the circuit board, and avoid the clamping and fixing mechanism from being easily loosened and shifted when accidentally colliding with the clamping and fixing mechanism during use, causing the workpiece to loosen and fall off, so that the clamping and fixing mechanism can take into account both the convenience of loosening and tightening operation and the stability of clamping and fixing.

[0048] Preferably,

[0049] A positioning sleeve 303 is welded to the head end of the cross brace section of the L-shaped driving rod 3, and the positioning sleeve 303 is slidably matched with the positioning short shaft 103;

[0050] A long slot 1022 is formed on one side of the two strip-shaped clamping plates 102 facing each other, and two ends of the circuit board are correspondingly plugged into the two long slots 1022 .

[0052] A U-shaped sliding frame 401 is welded to the top of the positioning rack 4, and the U-shaped sliding frame 401 penetrates and slides with the front end portion of the right longitudinal support side rod;

[0053] The elastic compression sleeve used for pushing and installing the positioning rack 4 is mounted on the vertical support part of the U-shaped sliding frame 401.

[0054] Preferably,

[0055] A U-shaped vertical support frame 3011 is welded to the top of the front sliding sleeve 301, and a vertical sliding push shaft 302 is slidably installed on the U-shaped vertical support frame 3011. The bottom end of the push shaft 302 is in contact with the U-shaped sliding frame 401. The U-shaped sliding frame 401 can be pushed downward by the push shaft 302 to control the positioning rack 4 and the plug block 3012 to separate and release the two strip clamps 102. The push shaft 302 is indirectly set on the L-shaped driving rod 3 through the front positioning sleeve 303, which can be used The L-shaped driving rod 3 is driven to slide forward and backward, and then the push shaft 302 can be used to slide the L-shaped driving rod 3 forward and backward to loosen or tighten the circuit board, and the positioning rack 4 can be loosened or lowered at the same time. Compared with the prior art in which the sliding drive component of the positioning rack 4 is separated from the L-shaped driving rod 3 and is arranged separately, the trouble of sliding the positioning rack 4 and driving the L-shaped driving rod 3 step by step can be omitted, which helps to simplify the overall loosening and tightening operation steps of the clamping and fixing mechanism, and is convenient and efficient to use.

[0056] It is worth noting that: when the two strip clamps 102 are clamped against the circuit board and the plug block 3012 cannot accurately fit and plug with the positioning rack 4, if the two strip clamps 102 or the structure driving them are collided, causing the two strip clamps 102 to move away from each other and loosen and slide, the L-shaped driving rod 3 will drive the plug block 3012 to move forward to calibrate and complete the fitting and plugging with the positioning rack 4, so as to ensure the normal and effective implementation of the stable clamping function of the clamping and fixing mechanism;

[0057] A rectangular push block is welded to the bottom end of the push shaft 302 , and the bottom surface of the rectangular push block abuts against the top end of the U-shaped slide frame 401 .

The support frame 1 is rotatably installed through the two rotating shafts, and the circuit board clamped thereon can be flipped over and the horizontal angle of the circuit board during welding can be swung to adjust.

[0062] Preferably,

[0063] The top end portion of the left vertical support rod 201 is slidably installed with a plug-in positioning piece 202 through a spring push, and the plug-in positioning piece 202 is composed of a square rod sleeve and an L-shaped plug rod welded together, wherein the L-shaped plug rod is plugged into the positioning hole, and through the L-shaped plug rod, the plug-in positioning piece 202 can be plugged into the fixed positioning wheel 101, so that the support frame 1 remains in the use state after rotation adjustment.

[0064] Working principle: two connecting rods 1021, L-shaped driving rod 3 and two strip clamping plates 102 are connected together to form two crank slider mechanisms, which are actually mechanisms for clamping and fixing circuit boards. Through these two mechanisms, the L-shaped driving rod 3 can be pushed backward to drive the two strip clamping plates 102 to slide away from each other, loosening the circuit board. After the L-shaped driving rod 3 is loosened, the spring on the horizontal positioning shaft can rebound to push and drive the two strip clamping plates 102 to slide close to each other, thereby clamping and fixing the circuit board.

[0065] The insert block 3012 can be inserted and positioned in the L-shaped driving rod 3 to perform auxiliary fixing on the two strip clamps 102, so that the two strip clamps 102 and the entire clamping and fixing mechanism can stably clamp and hold the circuit board, and avoid the clamping and fixing mechanism being easily loosened and shifted when accidentally colliding with the clamping and fixing mechanism during use, so as to loosen and drop the workpiece;

[0066] It should be noted that: when the two strip clamps 102 are against and clamped on the circuit board, and the plug block 3012 cannot be accurately matched and plugged with the positioning rack 4 for assembly, if the two strip clamps 102 or the structure driving them are collided, causing the two strip clamps 102 to move away from each other and slide loose, the L-shaped drive rod 3 will drive the plug block 3012 to move forward for calibration and complete the matching and plugging with the positioning rack 4, so as to ensure the normal and effective implementation of the stable clamping function of the clamping and fixing mechanism. The U-shaped sliding frame 401 can be pushed downward through the push shaft 302 to control the positioning rack 4 to be pulled apart and separated from the plug block 3012, thereby loosening the two strip clamps 102, and the push shaft 302 is indirectly set on the L-shaped drive rod 3 through the front positioning sleeve 303, which can be used to implement forward and backward sliding drive of the L-shaped drive rod 3.
