The bottom of the connecting arm 96 is provided with a receiving groove 104 for receiving the first resetting piece 63, the receiving groove 104 penetrates through one end of the connecting arm 96 facing the housing 12, and two ends of the first resetting piece 63 are fixed to the receiving groove 104 and the slot 100 respectively. In the illustrated embodiment, a first fixing post 106 is disposed at an end of the receiving slot 104 away from the engaging cavity 56, a second fixing post 108 is disposed at an end of the inserting slot 100 away from the movable clamping arm 16, and two ends of the first resetting element 63 are respectively fixed to the first fixing post 106 and the second fixing post 108.

A second return element (not shown), preferably a compression spring, is also provided between the housing 12 and the locking element 34 for providing a pressure force for urging the locking element 34 towards the movable clamping arm 16. More specifically, the end wall 67 of the engaging cavity 56 on the side away from the movable clamping arm 16 is provided with a stop portion 76, two sides of the stop portion 76 are provided with notches 69, the locking member 34 is provided with a mounting position 78, and the mounting position 78 is located between the pivot portion 46 and the elastic arm 50. During assembly, the locking member 34 is connected to the stopping portion 76, such that the stopping portion 76 extends into the mounting portion 78, the connecting rods at two sides of the mounting portion 78 are respectively received in the notches 69 at two sides of the stopping portion 76, the pivoting portion 46 and the rotating portion 42 are located at the outer side of the stopping portion 76, and other portions of the locking member 34 are located in the matching cavity 56. The second restoring member is disposed in the mounting portion 78, and the second restoring member abuts between the stopping portion 76 and an end wall of the mounting portion 78 on a side away from the pivot portion 46.

Preferably, a positioning column 80 is disposed on an end wall of the mounting portion 78 on a side away from the pivot portion 46, and a corresponding end of the second resetting member is sleeved on the positioning column 80, so as to enhance the connection stability of the second resetting member. When the locking switch 32 rotates to move the locking member 34, the pressure of the second restoring member can fix the locking member 34, so that the locking member 34 and the locking switch 32 are fixed relative to the housing 12. After the locking switch 32 is turned upwards by a certain angle relative to the housing 12, the pushing force provided by the second reset member can make the locking member 34 move rapidly towards the movable clamping arm 16, so as to drive the locking switch 32 to turn rapidly to the right position; of course, in other embodiments, the second reset element may not be provided, and the user may manually turn the locking switch 32 to the proper position.

The rotating portion 42 has a first stopping surface 82 and a second stopping surface 84 adjacent to each other, wherein the first stopping surface 82 is disposed at the bottom of the rotating portion 42, and the second stopping surface 84 is disposed at a side of the rotating portion 42 facing the stopping portion 76. When the locking switch 32 is located at the open position, the first stop surface 82 abuts against the outer side surface of the end wall 67 of the matching cavity, the vehicle-mounted bracket base 10 is in the unlocked state, and the movable clamping arm 16 can move relative to the fixed clamping arm 14; when the locking switch 32 is in the closed position, the second stop surface 84 abuts against the outer side surface of the end wall 67 of the mating cavity, the vehicle-mounted bracket base 10 is in the locked state, and the movable clamping arm 16 is fixed relative to the fixed clamping arm 14.

It should be understood that in other embodiments, the positions of the rotating portion 42 and the pivoting portion 46 on the locking switch 32 and the locking member 34 can be interchanged, and when the locking switch 32 is in the open position, the first stop surface 82 abuts against the outer side surface of the stop portion 76; when the locking switch 32 is in the closed position, the second stop surface 84 abuts the outer side surface of the stop portion 76.

It should be noted that whether or not the movable clamp arm 16 extends outside the housing 12, the tooth 102 is disengaged from the rack 98 when the lock switch 32 is in the open position. At this time, the user can manually pull the movable clamping arm 16 out of the housing 12, clamp the first hook 26 and the second hook 28 in place, and clamp the movable clamping arm by the pulling force of the first restoring member 63 to fix the vehicle-mounted bracket base 10.

The center of the rotation axis of the rotation portion 42, i.e., the center of the axial hole thereof, is located at a shorter vertical distance from the first stopping surface 82 than the second stopping surface 84. During rotation of the locking switch 32 from the open position to the closed position as the locking switch 32 is threaded into the switch receiving channel 30, the locking switch 32 moves the locking member 34 away from the movable clamp arm 16, and the resilient arm 50 moves therewith and under the urging of the urging block 54, until the teeth 102 engage the rack 98, thereby locking the switch. Because the vertical distances from the first stopping surface 82 and the second stopping surface 84 of the rotating portion 42 to the center of the rotating shaft are different, after the tooth portion 102 is meshed with the rack 98, the locking switch 32 can be pressed into the switch accommodating groove 30, and simultaneously, the movable clamping arm 16 can be pulled into the housing 12 for a certain distance, so that the movable clamping arm 16 can be clamped more stably, and the clamping of the clamping arm is not unstable and loosened due to fatigue of the first resetting piece 63.

The utility model discloses on-vehicle support base 10 with locking function's theory of operation as follows:

when the locking switch 32 is in the closed position, the locking mechanism is in the locked state, the locking member 34 is in the second position, the second stop surface 84 abuts the outer side surface of the end wall 67 of the mating cavity, the resilient arm 50 is pressed by the pushing block 54 to be in the straightened state, the tooth portion 102 is engaged with the rack 98, and the movable clamping arm 16 is fixed relative to the fixed clamping arm 14.

When the locking switch 32 is in the open position, the locking mechanism is in the unlocked state, the locking member 34 is in the first position, the first stop surface 82 abuts against the outer side surface of the end wall 67 of the mating cavity, the resilient arm 50 is not pressed or is less pressed by the pushing block 54, the resilient arm 50 is in the inwardly inclined state, the tooth portion 102 is separated from the rack 98, and the movable clamping arm 16 is movable relative to the fixed clamping arm 14.

In the process of rotating the locking switch 32 from the closed position to the open position, the rotating portion 42 rotates upward in the notch 40, and the second stop surface 84 is changed from abutting against the outer side surface of the end wall 67 of the matching cavity to abutting against the first stop surface 82 against the outer side surface of the end wall 67 of the matching cavity, the locking switch 32 rotates under the limiting action of the projection 47, so that the rotating shaft 65 moves to one side close to the movable connecting arm 16, the locking member 34 moves from the second position to the first position, the elastic arm 50 loses the pressing action of the pushing block 54, the elastic arm 50 is reset to an inward inclined state under the self elastic force (or under the elastic force of the elastic member 53), the tooth portion 102 and the rack 98 are switched from the engaged state to the disengaged state, and at this time, the movable clamping arm 16 can move relative to the fixed clamping arm 14.

In the process of rotating the locking switch 32 from the open position to the closed position, the rotating portion 42 rotates downward in the notch 40, and the first stop surface 82 is changed from abutting against the outer side surface of the end wall 67 of the matching cavity to abutting against the second stop surface 84 against the outer side surface of the end wall 67 of the matching cavity, the locking switch 32 rotates under the limiting action of the projection 47, so that the rotating shaft 65 moves to the side away from the movable clamping arm 16, and further the locking member 34 moves from the first position to the second position, the elastic arm 50 is pressed by the pushing block 54 to overcome the self-elasticity of the elastic arm 50 (or overcome the elastic action of the elastic member 53) to deform outwards and straighten, and the pushing block 54 supports the elastic arm 50 to keep the straightened state, so that the tooth portion 102 is meshed with the rack 98, and at this time, the movable clamping arm 16 is fixed relative to the fixed clamping arm 14.

Since the vertical distance between the center of the rotating shaft of the rotating portion 42 and the first stopping surface 82 is smaller than the vertical distance between the center of the rotating shaft and the second stopping surface 84, the movable clamping arm 16 will be pulled a certain distance into the housing 12 and locked again when the locking switch 32 rotates from the open position to the closed position.
