Since the present invention discloses an indenter device having a pressure-proof mechanism, the principle of using the structure of the indenter and the liquid sucking component is well known to those skilled in the relevant art, so the following description ,no longer Make a full description. At the same time, the drawings in the following texts express the structural schematics related to the creative features, and do not need to be completely drawn according to the actual size.

Please refer to FIG. 1 , which is a preferred embodiment of the indenter device ( 2 ) having the anti-pressure mechanism according to the present invention. The indenter device 10 having the anti-pressure mechanism is mainly composed of a pressure head device 1 . And a pressure-proof mechanism 2 is composed.

As shown in FIG. 1 to FIG. 4 , the indenter device 1 has a body 11 , a pressing portion 12 pivotally connected to the body 11 by a rotating shaft 111 , a nozzle portion 13 and a base 14 . One end of the 13 protrudes from the pressing portion 12 and protrudes from the pressing portion 12 , and the other end is sleeved with the base 14 . One end of the base 14 is assembled with the body 11 , and the other end is sleeved with the nozzle portion 13 and protrudes outside the body 11 . And having a pocket 141 having a fitting surface 142 and a pair of convex portions 143.

The anti-pressing mechanism 2 is sleeved in the receiving groove 141 and can generate a sliding displacement in the receiving groove 141 when receiving the force, and includes a key portion 21, an interference portion 22 and a wing portion 23, which is in the embodiment. The portion 21 is a round key, and the interference portion 22 extends from the rear of the key portion 21, and the interference portion 22 and the key portion 21 have a stop portion 24 therebetween. The stop portion 24 and the outer edge of the base 14 can A locking portion is formed to limit the sliding range of the anti-pressing mechanism 2, and the wing portion 23 extends from both sides of the interference portion 22, and the wing portion 23 has a pair of hook portions 231 that can be engaged with the fitting surface 142 at the free end. And the bottom edge of the wing portion 23 has a pair of convex buckles 232 adjacent to the free end, the convex buckles 232 can be oppositely engaged with the convex portions 143, and the first buckle positions 233 are respectively provided on both sides of the convex buckles 232. And a second sliding position 234, according to which the anti-pressing mechanism 2 slides to the first sliding position 233, and the interference portion 22 and the bottom edge of the nozzle portion 13 abut each other to form an interference state, so that the pressing portion 12 cannot be pressed downward. In order to prevent the phenomenon of accidental pressing.

In addition, in the embodiment, the body 11 has a grip portion 112 for holding by the hand, and the pressing portion 12 has a force applying portion 121 for hand force, and the body 11 further has a joint portion. 113, can be assembled with a liquid storage container 4, the base 14 further has a set of portions 144 for accommodating and squeezing a sucking assembly 3, as shown in Fig. 8.

It is worth mentioning that in this embodiment, the convex portions 143 have an inclined portion 1431 on both sides of the convex portion 143, so that the anti-pressing mechanism 2 can smoothly slide. When the position is to be switched, the key of the anti-pressing mechanism 2 must be The portion 21 can be slid by the external force, and the hook portions 231 of the anti-pressure mechanism 2 are engaged with the fitting surface 142. Therefore, the anti-pressure mechanism 2 does not fall, and the risk of loss of parts can be effectively reduced.

Please refer to FIGS. 1 to 4 and FIG. 5 at the same time, and a schematic diagram of the interference prevention mechanism of the anti-pressure mechanism proposed in the present invention, wherein the anti-press mechanism 2 is pressed when the key portion 21 of the anti-press mechanism 2 is pressed. The first sliding position 233 is slidably engaged with the convex portions 143. At this time, the locking portion 24 and the outer edge of the base 14 can form a snap, and the anti-press mechanism 2 can no longer advance. At the same time, if the pressing portion 12 is pressed by force, the bottom edge of the nozzle portion 13 that is moved downward and the interference portion 22 of the anti-pressing mechanism 2 abut each other to form an interference state, as shown in Fig. 6, at this time, the pressing portion 12 It is impossible to press down to prevent accidental pressing.

Referring to FIG. 7, when the anti-press mechanism 2 releases the interference state, that is, the key portion 21 of the anti-press mechanism 2 is biased back to the initial state, the anti-press mechanism 2 slides to the second sliding position 234 and is opposite to the convex portion 143. At the same time, the bottom edge of the nozzle portion 13 and the interference portion 22 of the anti-press mechanism 2 are disengaged. As shown in Fig. 9, if the pressing portion 12 is pressed by the force at this moment, the nozzle portion 13 will be smoothly moved. Move and complete the pressing action, as shown in Figure 8.

In addition, when the key portion 21 of the anti-pressure mechanism 2 is biased back to the initial state, the hook portions 231 are engaged with the corresponding fitting surface 142, and the anti-press mechanism 2 can no longer be advanced in this position, and because The hook portions 231 are engaged with the fitting surface 142. As shown in FIGS. 9 and 4A, the anti-press mechanism 2 does not escape from the pocket 141, so the anti-press mechanism 2 does not fall. Can effectively reduce the risk of missing parts.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the patent application rights of the present invention; at the same time, the above description should be understood and implemented by those skilled in the art, so that the other does not deviate from the present invention. Equivalent changes or modifications made in the spirit of the disclosure should be included in the scope of the patent application.
