As shown in fig. 1 and fig. 2, in practical situations, the number of the rectangular grooves 11 and the push-pull devices 2 mainly depends on the size of the circuit board and the area of the main body, and the number of the rectangular grooves 11 can be adjusted by changing the size of the main body 1 according to practical requirements; the push-pull rod 22 is embedded in the groove channel 23, the push-pull rod 22 can move in the groove channel 23, and the clamp is suitable for circuit boards with different lengths by adjusting the position of the push-pull rod 22.

In this case, the jig can be used as a tool for storing the circuit board and also as a transfer tool for production. The utility model preferably enables the slotting depth of the rectangular groove 11 to be larger than the maximum height of the patches on the two sides of the circuit board, and avoids collision and damage caused by the fact that electronic components are higher than the rectangular groove 11 in the production and transportation processes.
The bottom surface and the side surface of the rectangular groove 11 are respectively provided with at least one boss 12, and the upper surfaces of the bosses 12 are all kept at the same horizontal height. The circuit board is supported, the bosses 12 keep the same horizontal height, and stable placement of the circuit board is guaranteed. In the actual production process, the height of the boss 12 should be greater than the maximum height of the two-sided electronic components, so that the situation that the bottom surface of the circuit board after being pasted is contacted with the bottom surface of the rectangular groove 11 to damage the electronic components is avoided. The difference between the upper surface of the boss 12 and the upper surface of the main body 1 is a second preset distance, the second preset distance is larger than or equal to the thickness of the circuit board, and the consequences that the circuit board is damaged due to uneven stress on two sides of the circuit board caused by the fact that the circuit board protrudes can be avoided in the process of mounting.
The inner side of one end of the rectangular groove 11 is provided with a boss 12, the outer side of the other end of the rectangular groove 11 and the upper cover 21 are provided with matched mounting holes 3, and the push-pull device 2 is fixed on the mounting holes 3 of the main body by screws.
The main body and the push-pull device 2 can be fixed in an adhesion mode, or a groove can be formed in the main body 1, and the push-pull device 2 is embedded in the main body through the groove. In connection with the embodiment of the present invention, it is preferable to perforate the main body 1 and the upper cover 21 of the push-pull mechanism 2, as shown in fig. 5, and then fix the main body 1 and the upper cover 21 through the mounting hole 3. The mode can avoid the use of adhesive fixation which is easy to lose efficacy at high temperature, and can also avoid the damage to the main body.

The push-pull 2 is inserted into the channel 23. In combination with the implementation of the present invention, the sectional area of the channel 23 should be slightly larger than the sectional area of the push-pull rod 22, so that the design can prevent the hole area from being too large, the push-pull rod 22 is deviated during the process of fixing the circuit board by the clamp, the circuit board is damaged, and the position of the push-pull rod 22 can be conveniently adjusted.
A first limit block 25 is arranged at one end of the push-pull rod 22 close to the rectangular groove 11, a second limit block 26 is arranged at the other end of the push-pull rod 22, the length of the push-pull rod 22 is greater than that of the channel 23, and after the upper cover 21 is fixed at one end of the rectangular groove 11, the first limit block 25 and the second limit block 26 are respectively arranged at two ends of the channel 23. A spring 28 is disposed in an area formed by the upper cover 21, the spring 28 is sleeved on the protruding rod 27, one end of the spring is abutted against the first limit block 25, and the other end of the spring is abutted against the upper cover 21.
The core component of the push-pull device 2 is a push-pull device, and can be divided into a spring push-pull device, a cylinder push-pull device or a rubber push-pull device according to different push-pull devices. There are preferred embodiments of the present invention, and spring push-pull devices are preferably used, as shown in fig. 3 and 4, which show top and front views of the push-pull device of the present invention, respectively. In the actual surface mounting process, electronic components need to be welded on a circuit board, and the service life of rubber can be shortened due to high temperature; from the actual production, the requirement of the cylinder push-pull device on equipment is very high, and the reduction of the production cost is not facilitated.
Further, to achieve the function of the spring push-pull device, a compression spring is generally adopted, and the effect of fixing the circuit board is achieved by using the reaction force of the spring. In the embodiment of the utility model, the first limiting block 25 and the second limiting block 26 are arranged at the end of the push-pull rod 22, the spring 27 in the region formed by the first limiting block 25 and the upper cover 21 is compressed, so that the effective length (the maximum value of the length of the circuit board can be received) of the rectangular groove 11 is adjusted, and the circuit board is fixed between the rectangular groove 11 and the first limiting block 25 by using the reaction force of the spring 27.
The distance between the lower surface of the first limiting block 25 and the bottom of the rectangular groove 11 is less than or equal to the height of the boss 12.
To ensure that the circuit board is always kept horizontal in the clamping process, the bosses for supporting are kept at the same height, and the circuit board is kept horizontal by the two clamped ends without dislocation.

Under the actual condition, the lower surface of the first limiting block 25 is not in contact with the bottom surface of the rectangular groove 11, so that the clamping process is guaranteed, the circuit board is always kept horizontal, the dislocation is avoided, and the damage caused by uneven stress is avoided.
Where permitted, for example: the body is large enough and the channel 23 is long enough, and the matching push-pull rod 22 is also long enough, so that only the limit block 25 is arranged on the push-pull rod 22 near one side of the rectangular groove 11. On the premise that the push-pull rod 22 does not slide out of the channel 23, the effect of being compatible with circuit boards with different lengths can be achieved by adjusting the position of the push-pull rod 22, and at the moment, the spring 27 is easily damaged due to rebound of the spring 27. In combination with the present embodiment, it is preferable to provide the first stopper 25 and the second stopper 26 at two ends of the push-pull rod 22, so as to avoid the spring from being damaged by resilience. The first stop 25, the second stop 26, the length of the channel 23, and the spring 27 limit the maximum travel of the push-pull rod 22, and in practice, the ability of the fixture to accommodate circuit boards of different lengths is typically adjusted by adjusting the length of the push-pull rod 22 of the push-pull device 2.
