As can be seen, the base assembly 1 supports and fixes the limiting pin 10, the threaded hole 11, a pair of mounting grooves 12 and a plurality of guide pins 13, the limiting pin 10 is limitedly matched with the rotating module 2, which plays a limiting role in the rotating process of the rotating module 2, the threaded hole 11 plays a rotating limiting and guiding role for the rotating module 2, so that the rotating module 2 easily converts the rotating motion into linear motion through the threaded hole 11, the mounting grooves 12 play a supporting and limiting role for the buckle module 3, and a plurality of guide pins 13 play a guiding and positioning role when the base assembly 1 is matched with the product to be pressed, so that the base assembly 1 can be quickly and accurately matched with the product to be pressed.

[0017] As Figure 2 As shown, in this embodiment, the rotating module 2 includes a rotating block 20, a threaded tooth block 21 and a plurality of first screws 22, the threaded tooth block 21 is connected and matched at the bottom of the rotating block 20 through a plurality of first screws 22, the threaded tooth block 21 is threadedly matched with the threaded hole 11, the top end of the rotating block 20 is provided with a plurality of handle bosses 23, the bottom end of the rotating block 20 is provided with a rotating groove 24, and the rotating groove 24 is limitedly matched with the limiting pin 10. As can be seen, a plurality of first screws 22 connect the rotating block 20 and the threaded tooth block 21, the threaded tooth block 21 is threadedly matched with the threaded hole 11, so that the threaded tooth block 21 converts the rotating motion into linear motion, the rotating block 20 supports and fixes a plurality of handle bosses 23 and the rotating groove 24, a plurality of handle bosses 23 facilitate the operation of the operator, and the rotating groove 24 is matched with the limiting pin 10 to play a rotating stroke role for the rotating module 2.

[0018] As Figure 4As shown, in this embodiment, the snap-fit ​​module 3 includes a pair of snap-fit ​​blocks 30, a pair of rotating shafts 31, and four snap springs 32. The pair of snap-fit ​​blocks 30 are respectively limited and fitted within the pair of mounting grooves 12. The snap-fit ​​blocks 30 are rotatably fitted with the mounting grooves 12 via the rotating shafts 31. The four snap springs 32 are respectively limited and fitted at both ends of the pair of rotating shafts 31. A plurality of first springs 33 are provided between one end of the snap-fit ​​block 30 and the mounting groove 12. The two ends of the plurality of first springs 33 are respectively limited and fitted with the snap-fit ​​block 30 and the mounting groove 12. The other end of the snap-fit ​​block 30 is limited and fitted with both sides of the product to be pressed. Therefore, the mounting groove 12 provides support and limit for the latching block 30 and the rotating shaft 31. The rotating shaft 31 passes through the latching block 30, providing rotational engagement and fixation for the latching block 30. This makes the latching block 30 function like a seesaw, where one end moves closer and the other end moves further away, thus achieving a limiting engagement of the product to be pressed. Several first springs 33 push one end of the latching block 30 away, thereby clamping and limiting the product to be pressed.

[0019] like Figure 2 As shown, in this embodiment, the elastic pressing module 4 includes a floating block 40, a rotating connecting block 41, a plurality of equal-height screws 42, and a second screw 43. The rotating connecting block 41 is connected to the threaded block 21 through the second screw 43. The rotating connecting block 41 is limited to the floating block 40. The floating block 40 is connected to the base assembly 1 through the plurality of equal-height screws 42. A plurality of second springs 44 are provided between the floating block 40 and the base assembly 1. The plurality of second springs 44 are respectively looped around the plurality of equal-height screws 42. The two ends of the second springs 44 are respectively limited to the floating block 40 and the base assembly 1. The floating block 40 is limited to the product to be pressed. Therefore, the second screw 43 connects the rotating connecting block 41 to the threaded block 21, the plurality of equal-height screws 42 connect the floating block 40 to the base assembly 1, and the plurality of second springs 44 allow the floating block 40 to float and engage with the base assembly 1. At the same time, they also absorb downward pressure to prevent excessive downward pressure from the floating block 40 from damaging the product to be pressed. The rotating connecting block 41 transmits the downward motion of the rotating module 2 to the floating block 40, pushing the floating block 40 to press down on the product to be pressed.

[0020] like Figure 2As shown, in this embodiment, the top surface of the handle protrusion 23 is provided with an identification character 25. Therefore, the handle protrusion 23 provides support and fixation for the identification character 25, which serves as an indicator, facilitating understanding and operation by the operator.

[0021] In this embodiment, the working principle of this utility model is as follows:

[0022] like Figures 1 to 4 As shown, the working principle of this utility model consists of two processes.

[0023] The pressing motion process: The operator firmly grasps one end of the latching blocks 30 on both sides of the present invention with both hands, and then the present invention is aligned with the pin holes on the product to be pressed through several guide pins 13. Then the latching blocks 30 are fastened to the product to be pressed. The operator manually rotates the rotating block 20 until the limiting pin 10 restricts the rotating block 20 from rotating further, at which point the manual rotation action is completed. At this time, after being squeezed by the downward stroke of the rotating module 2, the elastic pressing module 4 uses the second spring 44 to generate elastic force, causing the mating needle module to also produce a downward pressing action until the corresponding stroke and pressure are reached.

[0024] The upward movement process requires first rotating the rotating block 20 in the opposite direction, causing the elastic pressing module 4 to disengage from the product. At this time, the second spring 44 returns to its initial position, and then the operator can use both hands to pinch one end of the buckle block 30 on both sides. Since the second spring 44 does not press the product, the buckle block 30 has no elasticity, allowing the entire utility model to easily detach from the product and complete the pressing test.

[0025] This design has a foolproof function: when the rotating block 20 is not rotated and the pressing force of this utility model is released, the latching block 30 cannot be opened. It is necessary to rotate the rotating block 20 and rotate it upward a certain distance before the latching block 30 can be opened and the utility model can be removed.

[0026] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
