TECHNICAL FIELD
[0001] The utility model relates to display screen detection technical field, concretely is a guide column guide sleeve positioning sliding type compression joint device. BACKGROUND
[0002] Display screen compression joint device is a kind of equipment for repairing and assembling display screen, mainly for connecting the various parts of display screen together tightly, ensure its normal work. The main working principle of display screen compression joint device is by mechanical pressure and temperature to repair or assemble display screen. Specifically, compression joint device utilizes mechanical pressure to tightly adhere the various components of display screen (such as display panel and protective glass) together, remove the air layer between them, so as to realize full bonding effect. In addition, compression joint device can also adjust temperature as needed to achieve better repair effect. Display screen compression joint device is mainly applied to the repair and assembly of liquid crystal television screen. In home, repair shop and other places, compression joint device is widely used to repair the damage of liquid crystal television screen, such as bright line and other problems. By using compression joint device, not only the display effect of screen can be restored, but also the service life of screen can be prolonged.
[0003] Based on the above, the present inventor found that there are the following problems: the compression joint device now guides and positions the compression joint display screen by a set of slider guide rail device when compressing screen, and the flatness and repeated compression position precision of compression depend on the machining precision and installation precision of slider guide rail device. The positioning gap of slider guide rail is too large, which leads to slightly poor installation precision, and there is often a phenomenon of compression position deviation during use, which is not easy to control flatness, and it is very easy to deform to the other side, repeatedly deformed, so that the material loses stability.
[0004] Therefore, in view of the above, the existing structure and defects are improved, and a guide column guide sleeve positioning sliding type compression joint device is provided to achieve the purpose of having more practical value. INVENTION CONTENTS

Since the length of the guide sleeve is smaller than the length of the guide post, one end of the guide post is located outside the guide sleeve, so that there is a gap between the pressure block and the fixed block. When the pressure block moves upward, the guide post will move upward in the guide sleeve and squeeze the spring, so that the pressure block and the fixed block are closed to complete the crimping work. The up and down movement of the pressure block always follows the sliding trajectory of the guide post and guide sleeve.
