In order to realize fixation after quick adjustment and provide two fixing points for use, an upper fixing part and a lower fixing part positioned below the upper fixing part can be arranged in the limiting chute 31; and the other connection rod part 51 is switchably fixed to the upper fixing part and the lower fixing part. Like this, when the low level installation is carried out to needs, can be earlier through the operation for connecting rod portion 51 switches to be fixed in down the fixed part, can control like this and remove axle 3 and descend fast, carries out accurate secondary adjustment through regulating spindle 2 again, thereby very big improvement the convenience and the efficiency of installation. Similarly, when high-position installation is required, the connecting rod part 51 can be switched and fixed to the upper fixing part through operation, so that the moving shaft 3 quickly rises to a high-position, and then accurate secondary adjustment is performed through the adjusting shaft 2. Of course, the present application may also only realize that the connecting rod portion 51 slides in the limiting sliding groove 31, and certainly, the present application does not play a good role in terms of improving the installation efficiency, and a person skilled in the art may select the connecting rod portion according to actual needs.
Further, as shown in fig. 6 to 7, the way of switching the upper fixing portion and the lower fixing portion of the connecting rod 51 in the limiting chute 31 can be realized as follows: a clamping block 311 is arranged in the position close to the top of the limiting chute 31; the top of the clamping block 311 is provided with a clamping groove for clamping a connecting rod part 51, and the clamping groove is used for forming an upper fixing part; a guide block 312 in an inverted triangular block structure is arranged at the top in the limiting chute 31 and right above the clamping block 311; the bottom of the guide block 312 is provided with a first guide surface and a second guide surface which are intersected and obliquely arranged; a first sliding cavity channel communicated with the clamping groove is defined by one side wall of the clamping block 311, the first guide surface, the top wall of the limiting sliding groove 31 and one side wall of the limiting sliding groove 31; the other side wall of the clamping block 311, the second guide surface, the top wall of the limiting sliding groove 31 and the other side wall of the limiting sliding groove 31 form a second sliding rail cavity communicated with the clamping groove in a surrounding mode; a clearance space respectively communicated with the first sliding cavity channel and the second sliding cavity channel is formed between the bottom of the clamping block 311 and the bottom of the limiting sliding groove 31; a non-return block 313 higher than the first sliding cavity channel is arranged between the guide block 312 and the clamping block 311; the reverse stop block 313 is connected with the top of the stop block 311 and is provided with a first side surface superposed with the first guide surface and a second side surface superposed with the second guide surface; a communicating groove 314 is formed in the position, close to the check block 313, of the second sliding cavity channel; the first side surface of the communicating groove 314 is overlapped with the second guide surface, and the second side surface is parallel to the second guide surface and is tangent to the clamping groove; the communicating groove 314 is higher than the check block 313, and forms a step surface superposed with the first guide surface with the check block 313; the bottom of the limiting chute 31 forms a lower fixing part and is located at the bottom of the clamping block 311 on one side close to the second sliding cavity.
Specifically, as shown in fig. 6 and 7, if the connecting rod 51 in the upper fixing state is switched to the lower fixing state, the low-position quick adjustment is realized. At this time, the moving shaft 3 can be further pressed by pressing the display module 7, so that the connecting rod part 51 can move along the step surface coinciding with the first guide surface, and the anti-stop block 313 moves into the first sliding cavity channel, because the fixing ring 100 has the function of fixing the limiting rod 5 in the radial direction, the limiting rod 5 can cling to the bottom of the sliding cavity after entering the first sliding cavity channel, because the anti-stop block 313 is higher than the bottom of the first sliding cavity channel and has the second side surface coinciding with the second guide surface, at this time, the connecting rod part 51 in the first sliding cavity channel can not return due to the height difference condition, and can also slide down along the second side surface coinciding with the second guide surface to the bottom of the limiting sliding groove 31 under the action force of the reset spring 6, namely, to the lower fixing part, so as to complete the low position fast adjustment. Similarly, when switching back to the high position, that is, when the fixing portion is fixed in the adjustment, the display module 7 may be pressed again, and then the driving moving shaft 3 moves downward continuously, so that the connecting rod portion 51 moves upward, because the lower fixing portion formed at the bottom of the limiting sliding groove 31 is located at the bottom of the clamping block 311 on one side close to the second sliding cavity channel, the connecting rod portion 51 does not enter the first sliding cavity channel again when moving upward, but enters the second sliding cavity channel, when the connecting rod portion 51 moves to the communicating groove 314 in the second sliding cavity channel, the display module 7 may be loosened slowly at this time, because the second side surface of the communicating groove 314 is parallel to the second guide surface, and when loosening is slow, under the acting force of the return spring 6, the connecting rod portion 51 may slide into the clamping groove along the second side surface of the communicating groove 314, so that the connecting rod portion 51 returns to the high position fixing position. In this embodiment, the locking groove may be an arc-shaped groove, and the locking block 311 may be configured as shown in fig. 6 and 7, but of course, other applicable configurations may also be used, and are not limited specifically.
Further, as shown in fig. 1 and fig. 3, the magnetic element 4 includes a magnet block 41 and a threaded post 42; the threaded column 42 is fixed at the bottom of the magnet block 41; the top of the moving shaft 3 is provided with a threaded hole 33 which is in threaded connection with the threaded column 42. The magnet block 41 and the threaded post 42 may be integrally formed or welded together, and are not limited in particular. Design like this, make things convenient for magnetism to inhale the installation of piece 4 and dismantle, improve and maintain the convenience.
Further, as shown in fig. 8, a spring escape groove 34 is provided in the outer peripheral wall of the moving shaft 3 in the axial direction thereof; the spring escape groove 34 extends downwards to the bottom of the movable shaft 3; the first end of the return spring 6 is in contact with and abuts against the bottom of the mounting cavity 20, and the second end of the return spring is in contact with and abuts against the top wall of the spring avoiding groove 34. As the adjusting shaft 2 has the first shaft section 21, the second shaft section 22, the third shaft section 23, and the fourth shaft section 24, the bottom of the return spring 6 may contact and abut against the bottom inside the third shaft section 23, rather than directly contact and abut against the bottom of the mounting cavity 20. In addition, the spring avoiding groove 34 can be arranged opposite to the limiting sliding groove 31, and the situation that the limiting rod 5 interferes with the return spring 6 is avoided.
Specifically, the spring avoiding groove 34 can be arranged to extend the space length for accommodating the spring, so that the amount of movement of the moving shaft 3 in the axial direction is not limited by the minimum compression amount of the spring, and more deformation can be used, so that the amount of movement of the moving shaft 3 is more, and those skilled in the art can make appropriate changes based on the amount of movement, and are not limited specifically.
While the above-described embodiments of the present invention have been illustrated and described in detail, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details or with other methods, components, and arrangements of parts.
