Engagement component is equipped between the upper surface of drive sleeve and the lower surface of taper knob.
The upper end of the transmission shaft, which is equipped with, makes taper knob hold down assembly with what drive sleeve cooperated.
The upper surface of the drive sleeve and the lower surface of taper knob are equipped with the ratchet of engagement.
The upper surface of the drive sleeve is equipped with several holes, and the lower surface of taper knob is equipped with several protrusions, protrusion with
Hole cooperation.
The side of the drive sleeve is equipped with the position-limit mechanism of limitation transmission shaft rotation angle.
The position-limit mechanism includes the limited block for being connected to drive sleeve side, and limited block is equipped with the limiting slot of arc,
It further include the gag lever post for being fixed on flange and protruding into limiting slot.
The adjusting block that can be slided is equipped in the limiting slot, the limited block is equipped with the adjusting connecting with adjusting block
Screw.
The upper surface of the drive sleeve and the lower surface of taper knob are equipped with the rectangular teeth of engagement.
In conclusion the utility model has the following beneficial effects:
The utility model improves handle regulating mechanism, so as to be positioned in any angle, even
It connects and operates, be user-friendly for using the problem of improving teletransmission mechanism operating difficulties is further equipped with position restrainer
Structure can be defined the work angle of operating mechanism, avoid the problem that teletransmission mechanism operates transition.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, the handle regulating mechanism of nuclear power teletransmission mechanism comprising the transmission shaft 1 of teletransmission mechanism, it is described
Drive sleeve 10 is connected by key on transmission shaft 1, including the taper knob 2 being set on transmission shaft, taper knob 2 is equipped with handle
20, engagement component 3 is equipped between the upper surface of the drive sleeve 10 and the lower surface of taper knob.
The utility model improves handle regulating mechanism comprising drive sleeve and taper knob, the two pass through engagement
Component is driven, taper knob can in any angle by engagement component drive drive sleeve, i.e., no matter handle regulating mechanism
Use environment it is how poor, user can find suitable angle and drive to transmission mechanism, be user-friendly for grasping
Make, also facilitates and installed.
The upper end of the transmission shaft 1 be equipped with cooperate taper knob and drive sleeve hold down assembly 4, setting holds down assembly
For guaranteeing the connection reliability between taper knob and drive sleeve, in present embodiment, hold down assembly including being connected to transmission shaft
On hold-down bolt 40 and compress piece 41, locked by hold-down bolt between taper knob and drive sleeve.
As shown in Figure 1, the upper surface of drive sleeve 1 and the lower surface of taper knob is equipped with the ratchet of engagement
30。
The upper surface of drive sleeve 10 as described in Fig. 2, Fig. 3 and Fig. 4 is equipped with several holes 101, the lower surface of taper knob 2
Equipped with several protrusions 201, protrusion 201 cooperates with hole 101.
Above two structure for realizing the power between drive sleeve and taper knob transmitting, thus drive transmission shaft turn
Dynamic, two kinds of structures facilitate taper knob to be cooperated in any angle with drive sleeve, user-friendly, overcome the prior art
The problem of middle handle and transmission shaft fit angle are single, can usually interfere with flange.
As shown in figure 5, the side of the drive sleeve 10 is equipped with the position-limit mechanism 4 of limitation transmission shaft rotation angle, setting
Position-limit mechanism be used to limit the angle of transmission shaft rotation, avoid the occurrence of and be opened and closed problem not in place, ensure that transmission mechanism
Reliability.
