[0010] The effect achieved by the above components is that under the action of the first spring, the sliding rod can push the arc-shaped plate to be pressed against the surface of the table leg for fixation.

[0011] Preferably, a pad is fixedly connected to the side surface of the card frame, and the pad is a rubber plate.

[0012] The effect achieved by the above components is: under the action of the pad, the table legs will not directly contact the inner wall of the card frame when being fixed, thereby avoiding the phenomenon of damage to the table legs due to rigid contact; when the table legs need to be fixed, the table legs are placed inside the card frame, and under the action of the first spring, the sliding rod can push the arc plate to squeeze on the surface of the table legs for fixation; under the action of the pad, the table legs will not directly contact the inner wall of the card frame when being fixed, thereby avoiding the phenomenon of damage to the table legs due to rigid contact; when the table legs are stuck inside the card frame, the card rod is pressed and inserted into the interior of the sliding rod, thereby achieving the fixing effect.

[0013] Preferably, the anti-tilt device comprises a round rod slidably connected to the top of the clamping block, and the top of the round rod is fixedly connected to a rectangular rod.

[0014] The effect achieved by the above components is that, under the action of the rectangular rod and the round rod, the table legs with the screw holes positioned will not tilt, thereby facilitating installation.

[0015] Preferably, an anti-slip strip is fixedly connected to the surface of the rectangular rod, and the anti-slip strip is a rubber strip.

[0016] The effect achieved by the above components is that, under the action of the anti-slip strip, the table legs will not move between the clamping block and the rectangular rod.

[0017] Preferably, a second spring is sleeved on the surface of the round rod, and two ends of the second spring are fixedly connected to the upper top of the clamping block and the bottom of the rectangular rod respectively.

[0018] The effect achieved by the above components is that under the action of the second spring, the rectangular rod can squeeze the table leg to prevent the table leg from tilting.

[0019] Preferably, a locking rod is inserted into the side surface of the locking block, and one end of the locking rod is inserted into the interior of the round rod.

[0020] The effects achieved by the above components are as follows: under the action of the positioning rod, the rectangular rod can fix the round rod after squeezing the table leg onto the surface of the clamping block; when the table leg is positioned, the table leg is inserted between the rectangular rod and the clamping block; under the action of the second spring, the rectangular rod can squeeze the table leg to prevent the table leg from tilting; under the action of the anti-slip strip, the table leg will not move between the clamping block and the rectangular rod; under the action of the positioning rod, the rectangular rod can fix the round rod after squeezing the table leg onto the surface of the clamping block, thereby achieving the anti-tilting effect.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the present invention, a fixing device is provided, and when the table leg needs to be fixed, the table leg is placed inside the card frame. Under the action of the first spring, the sliding rod can push the arc plate to squeeze on the surface of the table leg for fixing. Under the action of the pad, the table leg will not directly contact the inner wall of the card frame when being fixed, thereby avoiding the phenomenon of damage to the table leg due to rigid contact. After the table leg is stuck in the card frame, the card rod is pressed and inserted into the interior of the sliding rod, thereby achieving the fixing effect, thereby solving the problem that the card frame cannot fix table legs of different sizes and thus cannot be assembled.
