It should be noted that the height of the pressing plate 107 matches the height of the caulking groove 105,

in this embodiment, inserting the supporting block 201 into the engaging groove 104 pushes away the pressing plate 107, and the connecting plate 106 is moved upward under the action of the second spring 106c to clamp the supporting block 201 to the top plate 103.

It should be noted that the clamping assembly 200 and the driving belt 100 are provided with two groups, which are symmetrically disposed at two sides of the flexible circuit board for cooperation.

Example 2:

referring to fig. 1 to 4, the difference between the present embodiment and the previous embodiment is that a clamping groove 201a is provided on the side surface of the supporting block 201, and the side end of the top plate 103 is embedded in the clamping groove 201 a;

the insertion plate 201b at the lower side of the locking groove 201a is attached to the connection plate 106 and is inserted into the engagement groove 104.

The guide groove 201c is formed in the top of the supporting block 201, the guide pillar 202a is arranged at the bottom of the hold-down piece 202, and the guide pillar 202a is located in the guide groove 201 c.

The support block 201 may be disposed in a guide rail a, where the guide rail a is perpendicular to the driving belt 100, and the bottom surface of the guide rail a is at the same level as the bottom surface of the pressing plate 107, and the support block 201 is pushed to engage with the side end of the top plate 103 by the push rod motor.

A limiting groove 201d is formed in the bottom of the guide groove 201c, a limiting plate 202b is arranged at the bottom of the guide post 202a, and the limiting plate 202b is arranged in the limiting groove 201 d;

the stopper plate 202b is connected to the stopper groove 201d side by a third spring 202 c.

It should be noted that, the hold-down member 202 is a plate or block structure, the size of the limit groove 201d is larger than that of the guide groove 201c, the guide post 202a is matched with the guide groove 201c in size, the limit groove 201d is matched with the limit plate 202b in size, in this embodiment, the third spring 202c connects the upper side of the limit plate 202b and the top surface of the limit groove 201d, in the initial state, the limit plate 202b is located in the middle of the limit groove 201d, and a certain distance is left between the hold-down member 202 and the support block 201.

Further, the limiting plate 202b is made of magnetic material, a magnet is arranged on the inner side of the end portion of the top plate 103, when the supporting block 201 is clamped on the top plate 103, the rear magnet is clamped to adsorb the limiting plate 202b, so that the pressing piece 202 moves downwards to shorten the distance between the pressing piece and the supporting block 201, and clamping is achieved.

The bottom of the supporting block 201 is provided with pit groups 201e, and the distance between the pit groups 201e is the same as the distance between the ball groups 106 d;

the two sides of the pit group 201e are provided with arc grooves 201f, and the pit group 201e in the arc grooves 201f is at the lowest point.

The portion of the ball protruding from the web 106 is sized to fit the dimple in the dimple set 201e, and it should be noted that the dimple set 201e is located in the middle of the arc groove 201 f.

One of the problems to be solved by the present invention is that the supporting block 201 having the clamping function in the prior art needs to be clamped at a specific position of the driving belt 100 during the clamping process on the driving belt 100, and the supporting block 201 cannot be inserted at will to realize the clamping and fixing.

Specifically, the clamping groove 201a corresponds to the position of the top plate 103, the position of the inserting plate 201b corresponds to the position of the pressing plate 107, and in the inserting process, the inserting plate 201b moves above the ball group 106d and pushes the pressing plate 107, so that the pressing plate 107 is pushed into the caulking groove 105, and the connecting plate 106 is lifted, so that the ball group 106d is embedded into the pit group 201 e.

Referring to fig. 3 and 4, the insert 201b pushes the contacted pressing plate 107 (1) and pressing plate 107 (2) away, the insert 201b is located on the connecting plate 106 (3) and the connecting plate 106 (4) at the same time, if the ball group 106d corresponds to the pit group 201e directly, the direct ball group 106d is correspondingly embedded into the pit group 201e, so as to realize fixed connection.

If the ball group 106d does not correspond to the pit group 201e, the ball group 106d must correspond to a position of the arc groove 201f, and the ball group 106d slides into the pit group 201e along the arc groove 201f, which is actually embodied in that the supporting block 201 moves laterally a distance to the pit group 201e and falls into engagement on the ball group 106 d.

After sliding in place, the magnets provided in the top plate 103 correspond to the stopper plates 202b, and the stopper plates 202b are attracted to move the hold-down member 202 downward to hold the flexible circuit board.

It should be noted that, the position where the supporting block 201 is actually fixed and the position where the supporting block is inserted are offset from each other, and the offset is at most the distance between two adjacent ball groups 106d, and can be adjusted according to the actual situation to reduce the influence of the offset.
