The card base 1 and the pressing block 2 are preferably designed as an arch structure, the card base 1 is provided with an integral groove matching the shape of the pressing block 2, the pressing block 2 can be completely matched and connected in the integral groove, the pressing block 2 moves up and down relative to the card base 1, and the shaping grooves 13 are provided on both sides of the integral groove as slide rails for the pressing block 2 to move up and down, which can limit the sliding track of the pressing block 2 and prevent the pressing block 2 from shaking left and right.

[0024] The hook 3 includes a clamping strip 31 and a rotating shaft 32. The pressing block 2 is provided with a clamping strip groove 21. The clamping strip 31 is arranged in the clamping strip groove 21 and fixed to the pressing block 2 through the rotating shaft 32. The pressing block is provided with a rotating shaft through hole 22 on the side wall. The rotating shaft 32 passes through the clamping strip 31 and the rotating shaft through hole 22 to fix the clamping strip 31 in the clamping strip groove 21. The rotating shaft 32 is connected to the clamping strip 31, and the clamping strip 31 can swing around the rotating shaft 32. Holes are provided at the top of the clamping strip 31 and at the corresponding positions of the clamping strip groove 21. The elastic block 4 includes a third elastic block 43. The third elastic block 43 is connected between the top of the clamping strip 31 and the clamping strip groove 21 through the holes and provides an outward elastic force to the top of the clamping strip 31. A barb 33 is provided at the bottom of the clamping strip 31. The clamping strip 31 is clamped into the self-locking groove 11 through the barb 33. The holder 1 is provided with multiple self-locking grooves 11 of different heights. The design of the multiple self-locking grooves 11 can achieve a variety of different self-locking heights for clamping objects of different heights.

[0025] The pressing block 2 is provided with a guide hole 23, and the guide rod 5 passes through the guide hole 23 and is fixed on the base 1. A rod cap 51 is provided on the top of the guide rod 5. The diameter of the guide hole 23 is larger than the diameter of the rod body of the guide rod 5 and smaller than the diameter of the rod cap 51. When the pressing block 2 pops up, the rod cap 51 pushes the top of the pressing block 2 and limits the height of the pressing block 2 to pop up. The guide rod 5 is an axis screw, the first elastic block 41 is a spring, and the base 1 is provided with a threaded hole. One end of the spring is fitted and connected to the bottom of the pressing block 2 and aligned with the guide hole 23, and the other end is fitted and connected to the top of the base 1 and aligned with the threaded hole. The axis screw passes through the guide hole 23 and the spring and is tightened in the threaded hole. The axis screw connects the pressing block 2 and the base 1, and a spring is added in the middle, so that the pressing block 2 is pressed down and automatically popped up along the tracks on both sides of the base 1 with the axis screw as the axis. The guide rod 5 and the first elastic block 41 can be connected on the same axis at the same time, which saves space and concentrates the force; of course, according to actual applications, the positions of the guide rod 5 and the first elastic block 41 can be staggered to achieve the function of directional movement along the guide rod 5.

[0026] The bottom of the pressing block 2 is provided with a boss 24, and the holder 1 is provided with a through slot 14 at a position corresponding to the boss 24.

After the pressing block 2 is self-locked, the elastic force generated by the compression and deformation of the spring presses the object, which is suitable for applications in environments with thermal expansion and contraction.

[0027] The first elastic block 41, the second elastic block 42, and the third elastic block 43 are preferably springs, but are not limited to springs, and all structures that play an elastic role can achieve this function.

[0028] When the mechanism is pressing an object, the pressing block 2 is manually pressed to move it downward along the fixed slide groove 13 of the base 1, and the hook 3 slides against the base 1 under the elastic force of the third elastic block 43 until it moves to the self-locking groove 11 and the hook 3 is locked in the self-locking groove 11. The pressing block 2 is fixed at a certain height position of the base 1 under the action of the first elastic block 41. At this time, the second elastic block 42 also squeezes the object to be fixed 6, and the object 6 is pressed tightly by the elastic force. According to the height and force degree of the object to be fixed 6, the hook 3 can be adjusted to any level of the self-locking groove 11; when unlocking, press the top of the card strip 31 that is tilted to both sides to disconnect the connection between the hook 3 and the self-locking groove 11, and rebound to the original height under the action of the first elastic block 41 to complete the unlocking.

[0030] On the basis of the first embodiment, the hook 3 includes a limiting column, and a limiting column hole is provided at the bottom of the clamping strip 31, and the limiting column passes through the limiting column hole and is inserted into the self-locking groove 11. The barb 33 structure at the bottom of the clamping strip 31 can be replaced with a limiting column, and the limiting column is connected to the clamping strip 31. When the mechanism is pressing the object 6 to be fixed, the limiting column is in an open state, but when the clamping strip 31 slides to the self-locking groove 11 at the required height, the limiting column can be pressed to be inserted into the self-locking groove 11 for self-locking. When unlocking, the limiting column only needs to be pulled out of the self-locking groove 11 to complete the unlocking action.

[0031] The snap-on clamping mechanism includes but is not limited to structures that use barbs 33 or limiting columns to limit the position. Other structures that can be inserted into the self-locking groove 11 to achieve the self-locking function also fall within the protection scope of this case.

[0034] like Figure 3 As shown, the snap-on clamping mechanism includes a guide rail 7, and can also be used in conjunction with the guide rail 7: a guide rail groove 15 is provided at the bottom of the holder 1, the holder 1 is connected to the guide rail 7 through the guide rail groove 15, the guide rail 7 is fixedly connected to the first object to be fixed, the second object to be fixed is placed in the fixture groove 12, the holder 1 is slid to the clamping station, and the second elastic block 42 presses the second object to be fixed onto the first object to be fixed after the pressing block 2 is pressed to self-lock. The guide rails 7 are preferably two guide rails 7, and the two guide rails 7 can also play a role in limiting the second object to be fixed, and the holder 1 is preferably arch-shaped, and the guide rail groove 15 at its bottom is just used in conjunction with the two guide rails 7.

[0035] The guide rail groove 15 designed at the bottom of the card holder 1 in the snap-on clamping mechanism realizes the clamping operation of the snap-on clamping mechanism at any position on the guide rail. The application of the snap-on clamping mechanism is not limited to the guide rail 7, and it can also be fixed at a specified position, such as: a test stand, repeatedly executing batches of tested objects to be clamped one by one, waiting for testing, and releasing and removing the tested objects after the test is completed.

[0036] The working method of the snap-on clamping mechanism is as follows: put the snap-on clamping mechanism into the guide rail 7, place the object 6 to be fixed under the snap-on clamping mechanism, press the pressure block 2 down to the corresponding group of self-locking grooves 11 according to the height of the object, and release it. The hook 3 will self-lock and the object will be clamped. When it is necessary to release the clamping and take out the object, just press the top of the hook 3 inward with your thumb and index finger at the same time, and the hook 3 will release the self-locking and automatically lift up to release the object under the action of the spring.
