Problems solved by technology
[0002] In existing similar products, many lock bodies are equipped with anti-insertion structures, but there are defects such as many components, complex structures, high cost, and troublesome assembly. For example, Chinese Patent No. CN200420094269.2, published on October 19, 2005 , the invention name is a mortise door lock with an anti-insertion function. The application discloses a mortise door lock with an anti-insertion function. The disadvantage is that the anti-insertion function is to drive the transmission plate through the anti-insertion tongue , and then drive the anti-insertion insurance through the transmission plate to realize the anti-insertion function. The anti-insertion structure is still complicated and the cost is high

Embodiment Construction
[0030] Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail:
[0031] Such as figure 1 with figure 2 As shown, an anti-insertion device for a mortise door lock includes a safety tongue 2, an anti-insertion block 3, a rotating shaft 4, a torsion spring 5, a tension spring 6 and a bolt puller 7.
[0032] The safety tongue 2 is a device that is interlocked with the anti-insertion block 3 and the lock tongue pull block 7, and includes a strip-shaped groove 23 and a tension spring 6. The rear end of the safety tongue 2 is provided with a strip-shaped groove 23 and the safety tongue 2 is slidably set on the rotating shaft 4; the tension spring 6 is placed in the long strip groove 23, and one end withstands the rotating shaft 4, and the other end withstands the long shaft. The top wall of the strip groove 23. The rotating shaft 4 is fixed on the lock case.
[0033] Such as figure 2 As shown, the anti-inser...
