Figure 12 is a view of a locking element of the display device and locking the drawer position according to a second embodiment of the present invention. In this other embodiment, the lock can be a cylindrical pin or a pin of any shape, and the locking element 4 ′ has a substantially trapezoidal shape as shown in FIG. 12 and has a slope on which a first is provided. snap slot 401 'and a second snap slot 402'. With the displacement of the movable part 4 of the drawer from the OFF position to the TEST position, the lock comes into contact with a short side of the trapezoidal shape of the locking element 4 'and is blocked by this short side. By pressing the button at this time, the locking lever 1 is turned clockwise. When the latch of the locking lever 1 is about to be released from the short side of the trapezoidal shape of the locking element 4 ', the latch pin is snapped into the first latching slot 401' due to the biasing force of the biasing member, now the position display opening displaying the position mark TEST. When the movable part 4 of the drawer continues to move from the TEST position to the WORK position, it is necessary to press the button again, while the movable part 4 of the drawer is pushed towards the WORK position, and at this moment the latch pin is released from the first latching slot 401 'and moves along the slope of the locking member before it is locked in the second latching slot 402'. When the movable part 4 of the drawer continues to move from the WORK position to the TEST position, the button must be pressed again while pulling the movable part 4 from the drawer to the TEST position, and at this time the lock pin is released from the second latching slot 402 'and moves along the slope of the locking member until the latch pin is locked in the first latching slot 40Γ.
What is different from the embodiment described above is that after having moved from the TEST position to the WORK position, once the latch pin is released from the first latching slot 40Γ, the lock pin can be directly locked in the second latching slot 402 'without pressing the button. When the latch pin is moved to the TEST position after it clears from the second latching slot 402 'in the WORK position, the latch pin can be directly locked in the first latching slot 401' without pressing the button. Of course, a blocking can be arranged on the slope of the locking element 4 ', so that before the pin of the lock is directly snapped into the second snap slot 402' by moving from the TEST position towards WORK position, you still have to press button 2 beforehand. Similarly, another blocking can be arranged on the slope of the locking element 4 ′, so that before the pin of the latch is directly snapped into the first snap slot 401 ′ by moving from the WORK position to the TEST position, you must still press button 2 beforehand.
In the present embodiment, the manner of displaying the position marks in the position display opening 6 is also different. In the embodiment described above, once the latch pin is released from the locking element, the locking lever is returned to the initial position by the biasing element and the display opening of position 6 always displays the OLE position mark. However, in the present embodiment, since the locking member has a slope, the position marks are displayed in the position display opening 6 in a rolling manner by gradually rotating from a position mark to another.
The trapezoidal-shaped locking element in this embodiment can also be in an alternative form in which the oblique side of trapezoidal shape is formed by a stepped edge having at least two steps. In this variant, the lock can have any shape insofar as it can be blocked by the steps. The step positions correspond to the positions where the lock and the locking element are locked and the corresponding position marks are displayed. As a variant, the oblique side of the trapezoidal shape of the locking element may also form, by a toothed curved surface, at least two blockings which can be arranged in the toothed curved surface, the positions of the blockings corresponding to those where the lock is locked with the locking element and the corresponding position marks are displayed.
The embodiments described are only examples and should not be considered as limiting the invention, and the characteristics of the various embodiments can be used in combination to obtain other embodiments of the invention . The scope of the invention should only be limited by the appended claims. Many variants and modifications of the embodiments described are possible without departing from the scope of the invention.
