It is noted that the worm wheel 5 runs idle at least one turn, which may also facilitate the application of the lubricating oil.
In one of the preferred embodiments, the blocking portion comprises a second upright 11 slidably mounted on the outer wall of the guide rod 9;
the chain is characterized by further comprising two chain wheels 12 rotatably mounted on the inner wall of the mounting shell 4, a chain 13 is connected between the two chain wheels 12 in a transmission manner, one section of the chain 13 positioned below is fixedly connected with the second vertical bar 11 through a pin, a side block 21 is fixed on the outer wall of the first vertical bar 10, which is close to one section above the chain 13, a groove is formed in the bottom of the side block 21, a rotating claw 22 is rotatably mounted in the groove, a torsion spring for driving the rotating claw 22 to rotate outwards is mounted between the rotating claw 22 and the groove, and when the side block 21 slides towards the position close to the second vertical bar 11, the chain 13 presses the rotating claw 22 back towards the groove.
Referring specifically to fig. 5, 10 and 11, when the first vertical bar 10 moves along with the rotation of the screw 7, the chain 13 presses the rotating claw 22 back to the groove, and then when the cross bar 18 contacts the second vertical bar 11, the second vertical bar 11 moves against the cross bar 18, so as to achieve the purpose of driving the lifting block 15 to move downwards;
then when the first vertical bar 10 is reset and moves, the rotating claw 22 rotates outwards under the action of the torsion force of the torsion spring and is inserted into a gap on the chain 13, the chain 13 is stirred to move, the chain 13 starts to drive and drives the second vertical bar 11 to move away from the first vertical bar 10 under the drive action of the two chain wheels 12, so that the contact time between the transverse rod 18 and the second vertical bar 11 can be prolonged when the first vertical bar 10 moves again, namely the number of turns of the worm 6 driving the worm wheel 5 to idle can be increased;
therefore, when the first vertical bar 10 moves once, the second vertical bar 11 is far away from the first vertical bar, so that the lubricant can be added more and more uniformly, and if the worm wheel 5 and the worm 6 are worn, the more the number of idle rotation turns of the worm wheel 5 is, the larger the rotating error is, as known from the prior art, after the idle rotation is finished, the limit rod 31 on the connecting shaft 36 needs to be reinserted into the limit hole 33 in the hollow tube 32, therefore, when the wear of the worm wheel 5 and the worm 6 exceeds the preset value, the limit rod 31 cannot be reinserted into the limit hole 33, thereby achieving the purpose of reminding the user that the wear degree exceeds the preset wear degree, and further ensuring the precision of angle adjustment.
In one preferred embodiment, an electromagnet 39 is mounted on the inside top of the mounting frame 37 and a magnet 40 is mounted on top of the adjustment plate 38.
