A control rod 0300 is axially disposed in the insulating tube 0200. The operating rod 0300 passes through the guiding hole 0111 and can move axially; wherein, the axial direction is also the up and down direction in the figure.

Referring to FIGS. 7-9, the guiding device 0100 includes a guiding member 0110, a driving member 0120, a motion converting member 0130, and a positioning member 0140. The guiding hole 0111 is disposed on the guiding member 0110; the driving member 0120 is coupled to the guiding member 0110 and drives the movement. The conversion member 0130 is axially moved relative to the guiding member 0110; the positioning member 0140 can press the inner wall of the insulating tube 0200 radially outward to fix the guiding device 0100 in the insulating tube 0200, and the positioning member 0140 is located at the motion converting member 0130 and the guiding member 0110. between.

In this embodiment, the guide member 0110 has an annular shape, and the guide hole 0111 is an inner hole of the ring. The guide member 0110 is located inside the insulating tube 0200. For ease of assembly, the outer circle radius of the guide member 0110 is slightly smaller than the inner wall radius of the insulating tube 0200. In addition, the diameter of the guide hole 0111 is also slightly larger than the diameter of the joystick 0300, which is more advantageous for the joystick 0300 to move up and down.

The driving member 0120 includes a pressing portion 0121 and a connecting portion 0123 connected between the pressing portion 0121 and the guiding member 0110; the motion converting member 0130 and the positioning member 0140 are located between the pressing portion 0121 and the guiding member 0110.

Specifically, the connecting portion 0123 and the guide member 0110 are screwed. In the present embodiment, a thread is provided at one end of the connecting portion 0123 near the guide member 0110, and a screw hole 0113 is provided on the guide member 0110 to be engaged with the screw. When the driving member 0120 is rotated, the connecting portion 0123 is moved downward in the axial direction relative to the guiding member 0110, and the pressing portion 0121 is also moved axially downward by the connecting portion 0123.

Specifically, the pressing portion 0121 is located at one end of the driving member 0120 away from the guiding member 0110, and the pressing portion 0121 is vertically disposed with the connecting portion 0123. In the present embodiment, the driving member 0120 is three bolts disposed around the guiding hole 0111, the pressing portion 0121 is the head of the bolt, and the connecting portion 0123 is the screw portion of the bolt.

Of course, the driving member 0120 is not limited to the above form, and the driving member 0120 is a hollow bolt. The central hole of the hollow bolt can pass through the joystick 0300, but does not affect the axial movement of the joystick 0300.

Of course, the connection of the connecting portion 0123 and the guide member 0110 is not limited to the screw connection, and may be connected in other manners.

The purpose of the motion conversion member 0130 is to convert the axial movement of the pressing portion 0121 into the radial movement of the positioning member 0140.

In order to further strengthen the guiding action of the joystick 0300, the motion converting member 0130 is provided with an auxiliary guiding hole 0131, and the operating lever 0300 passes through the auxiliary guiding hole 0131.

A retainer 0150 is disposed on the inner wall of the auxiliary guide hole 0131. The function of the retainer 0150 is to protect the lever 0300 from direct contact with the motion converter 0130. Generally, the motion conversion member 0130 and the joystick 0300 are more rigid because of their own requirements; the retainer 0150 is made of a material that is less rigid than the two. In this way, it is possible to effectively protect the joystick 0300 from hard contact with the motion converting member 0130. Of course, depending on the actual needs, you can also not set Guard ring 0150.

For the same reason, the retaining ring can also be disposed on the inner wall of the guiding hole 0111 of the guiding member 0110 according to actual needs.

According to actual needs, a through hole 0133 is further disposed on the motion converting member 0130, and the connecting portion 0123 passes through the through hole 0133. This allows the components of the guiding device 0100 to be more tightly coupled. Of course, the motion converting member 0130 may not be provided with the through hole 0133, and the connecting portion 0123 is located outside the side of the motion converting member 0130 near the operating lever 0200, so that the connecting portion 0123 is also connected to the guiding member 0110 without affecting the motion converting member. 0130.

In the present embodiment, the side wall of the motion conversion member 0130 has a first motion conversion surface 0132, and correspondingly, the side wall of the positioning member 0140 has a second conversion surface 0142 that cooperates with the first motion conversion surface 0132. The first motion conversion surface 0132 is a slope or a conical surface. Correspondingly, the second motion conversion surface 0142 is a bevel or a conical surface. Of course, it is not limited to that the inclined surface cooperates with the inclined surface, or the conical surface and the conical surface cooperate, and the inclined surface and the conical surface cooperate.

In the present embodiment, the motion conversion member 0130 has a circular ring shape. The inner hole of the circular ring ring forms an auxiliary guiding hole 0131, and the side surface of the circular ring ring, that is, the conical surface forms a first motion conversion surface 0132. A through hole 0133 is provided around the auxiliary guide hole 0131. The upper bottom surface of the truncated cone abuts against the pressing portion 0021.

Correspondingly, the second motion conversion surface 0142 of the positioning member 0140 is also a conical surface. In the present embodiment, the conical surface is the inner side surface of the positioning member 0140.

Of course, the motion conversion component 0130 is not limited to one body, and may be separate, as long as the number of the split bodies corresponds to the number of the drive members 0120. For example, the portion of the truncated cone that is away from the bolt is hollowed out, leaving only the portion near the bolt.

In the present embodiment, in order to increase the contact area between the positioning member 0140 and the inner wall of the insulating tube 0200, the outer side surface of the positioning member 0140 is provided as a cylindrical surface 0141 matching the inner wall of the insulating tube 0200. Of course, it is not limited to a cylindrical surface.

The number of the positioning members 0140 is at least two. Preferably, a gap 0145 is provided between adjacent positioning members 0140. In this way, since the gap 0145 is disposed between the adjacent positioning members 0140, when the positioning member 0140 is moved radially outward, the end of the adjacent positioning member 0140 is interfered due to the influence of some uneven force. . Of course, the gap 0145 may not be provided. In general, when the positioning member 0140 is radially outward, the adjacent positioning members are naturally separated to generate a gap.

In this embodiment, the number of the positioning members 0140 is three, and is evenly distributed on the periphery of the conical surface of the motion converting member 0130, and a gap 0145 is disposed in the middle.

Of course, according to the installation requirements, the number of the positioning members 0140 is not limited to three, and may be two, four, or even more. Of course, the positioning member 0140 can also be one.

When moving, the pressing portion 0121 also moves axially downward under the action of the connecting portion 0123. The pressing portion 0121 abuts against the upper bottom surface of the motion converting member 0130, and the pressing portion 0121 presses the motion converting member 0130 downward. The first conversion surface 0132 of the motion conversion member 0130 is in contact with the second conversion surface 0142 of the positioning member, and the lower surface of the positioning member 0140 The surface abuts on the guiding member 0110, and the positioning member 0140 cannot move downward in the axial direction, and moves outwardly against the inner wall of the insulating tube 0200 under the action of the motion converting member 0130, thereby fixing the guiding device to the guiding device. Inside the insulation tube.

In the above guiding device, since the positioning member 0140 is independently disposed with respect to the guiding member 0110, the contact area between the positioning member 0140 and the inner wall of the insulating tube 0200 can be set larger in the axial direction or the radial direction, so that the guiding device can be more stably It is fixed to the inner wall of the insulation tube.
