72 carry certain radian, and the radian of two pieces of mainboards matches, and move portion 8 includes securing member 81 and mobile folder 82, mobile
Folder upper strata 821 is fixedly connected with the 4th mainboard 72, and the 3rd mainboard 71 blocks in mobile folder lower floor 822, and can carry out along the 3rd mainboard
Handheld Division structure in slide anteroposterior, Handheld Division 3 and embodiment one is identical, and Lighting Division 5 includes light source 51, power supply 52, light source control
The electric wire (being not drawn in figure) of system switch 53 and connection light source 51 and power supply 52, power supply 52 is located in Handheld Division 3, is light source 51
It is powered, light control switch 53 is located at the surface of Handheld Division 3, for controlling the opening and closing of light source.
With fluted 711, groove 711 is in inverted "L" shaped to 3rd mainboard 71, and securing member 81 is under the drive of mobile folder 82 recessed
All around moved in groove 711, realized the relative movement of the 4th mainboard 72 and the 3rd mainboard 71, folder to be moved 82 is moved to
During precalculated position, securing member is additionally operable to the position of fixed mobile folder 82.
Fig. 6 is the structural representation of move portion in embodiments of the invention two.
As shown in fig. 6, in move portion 8, securing member 81 has through the two-layer up and down of mobile folder 82 in mobile folder lower floor 822
There is the groove 8221 through mobile folder lower floor 822 upper surface, securing member 81 is in the case where mobile folder upper strata 821 drives in groove 8221
It is mobile, it is ensured that its bottom can be moved left and right along groove 711, and then the 4th mainboard 72 is driven relative to a left side for the 3rd mainboard 71
Move right.
As shown in Figure 5 and Figure 6, when relative movement before and after realizing the 4th mainboard 72 and the 3rd mainboard 71, by securing member 81
Unscrew, mobile folder 82, mobile folder 82 drives securing member 81 to be moved forward and backward in groove 711, while driving the 4th to lead
Plate 72 is moved together, it is to be moved to precalculated position when, tightening fastener parts 81 are fixed the position of the 4th mainboard 72；Work as reality
Along during the 3rd relative movement to the right of mainboard 71, i.e., when surgery tractor 200 broadens, securing member 81 is with mobile folder for existing 4th mainboard 72
Layer 821 is moved to the right through the groove 8221 of mobile folder lower floor 822 in groove 711, and the 4th mainboard 72 is on mobile folder
Under the drive of layer 821, realize and the relative movement to the right of the 3rd mainboard 71, to be moved to relevant position, tightening fastener parts 81,
The position of the 4th mainboard 72 is fixed, when needing that the width of surgery tractor 200 restores to the original state, only need to be by securing member to phase negative side
To movement, then fixed position.
In the present embodiment, the specification and the first mainboard 11 and the phase of the second mainboard 72 of the 3rd mainboard 71 and the 4th mainboard 72
Together, groove 711, length is 10cm, and width is 1cm, and the length of groove 8221 is 2cm, and width is 1cm, because of surgery tractor 200
In normal condition when, the bottom of securing member 81 is located at the right angle that two sides of the inverted "L" shaped groove of groove 711 connect, and is guarantor
The convenience of card surgery tractor width adjusting, can make securing member 81 in 82 left-of-center positions of mobile folder.
In addition, the fixed form of securing member 81 can be according to the thickness of the 3rd mainboard 71 in different ways, as the 3rd master
When the thickness of plate 71 is thicker, the bottom of securing member 81 711 is moved in a groove, then direct tightening fastener parts 81, when the 3rd mainboard
During 71 thinner thickness, groove 711 can be in the form of running through, and now the bottom of securing member 81 passes through groove, using bolt spiral shell
The fixed form of parent phase matching.
The effect of embodiment two and effect
According to the surgery tractor 200 for meeting the adjustable width of body mechanicses, length that embodiment two is provided, by pulling and supporting
Portion, move portion, Handheld Division and Lighting Division composition, move portion is not only acted as and drives the 4th mainboard in pulling part along the 3rd mainboard
The effect of relative movement, and play a part of to fix the 4th mainboard position, the surgery tractor simple structure that the present embodiment is provided,
Line width and depth adjustment can be entered to surgery tractor, because move portion plays fixation simultaneously, operation is further enhancing
The tolerance of drag hook.
The invention is not restricted to the scope of specific embodiment, for those skilled in the art, as long as respectively
Kind of change described claim limit and the spirit and scope of the present invention that determine in, these changes be it will be apparent that
All are using the innovation and creation of present inventive concept in the row of protection.
