Furthermore, the pressure head 5 is made of ceramic materials, so that heat conduction to the screen body can be reduced, and cracking (glue cracking) of a packaging area of the screen body is reduced.

Further, crimping formula tool still includes detecting element 8, and detecting element 8 sets up on pushing down handle 22 for detect the size of the overdraft that pressure head 5 applyed, make things convenient for operating personnel to observe.

Specifically, as shown in fig. 5 to 7, a first linear sliding groove 221 is provided on the push-down handle 22, the detection unit 8 includes a rolling element 81, a rocker arm 82, a sliding ring 83, a nut 85, and an adjustment rod 84, one end of the adjustment rod 84 is rotatably disposed on the push-down handle 22, the sliding ring 83 and the nut 85 are both sleeved on the adjustment rod 84, a compression spring 86 is provided between the sliding ring 83 and the nut 85, the nut 85 is in threaded connection with the adjustment rod 84, and the adjustment rod 84 can be rotated to adjust the compression amount of the spring. The rotating shaft of the rolling member 81 passes through the rocker arm 82 and the first strip-shaped sliding groove 221 in sequence, and the surface of the pressing handle 22 is provided with scale marks 222. The bearing of the rolling element 81 contacts with the upper surface of the fine adjustment disc 3, after the rolling element 81 is pressed by the fine adjustment disc 3 below, the reaction force makes the rolling element 81 move, so that the rocker arm 82 pushes the slip ring 83 to move back and forth, the slip ring 83 moves relative to the pressing handle 22, and the magnitude of the pressing force is displayed through the scale mark 222.

It can be understood that the adjusting rod 84 penetrates through the mounting hole 224 and extends out, the protruding portion of the nut 85 slides left and right along the second strip-shaped sliding groove 223, the rocker arm 82 can convert vertical movement received by the rolling member 81 into horizontal movement, the rocker arm 82 pushes the sliding ring 83 and the compression spring 86 to move left and right on the adjusting rod 84, and the pressure can be judged to be too high or too low by referring to the designated position scale on the housing.

It will be appreciated that in some application scenarios, as shown in fig. 7 and 8, the adjustment lever 84 only adjusts the slide ring 83 to indicate the designated position of the surface scale 222 of the push-down handle 22 when first used, and thus serves as a reference standard pressure, which is too low or the pressure head 5 does not contact the screen when the slide ring 83 is biased to the left of the designated position during daily operation, and too high when the slide ring 83 is biased to the right of the designated position.

This implemented still another screen lighting apparatus, this screen lighting apparatus include counterpoint mechanism and foretell crimping formula tool, and the screen body that awaits measuring is placed on counterpoint mechanism, and the screen body is located pressure head 5 under.
