[0037] One end of the adapter 200 is designed with a multi-prunion card slot, and a plurality of auxiliary card slots are provided on the multi-prunion card slot; such a fixed degree of fixed stability also increases the positioning function of the guide 300, and the internal multi-rib card groove fixing guidance The device 300 prevents rotation, and the positioning prism is increased on both sides for determining the position, and the upper end of the medium-segment adapter and the positioning groove are used to facilitate the placement of the front conductor. The multi-rib groove can be a hexagonal groove or an octaculation slot.
[0038] On the other end of the adapter 200, the central air design is used to place a fixed magnet in the center. There is a protruding prism on both sides of the outer end for fixing the handle 100 and the guide 300, preventing the offset and rotation, the bottom end of the prism It is more convenient to add.
[0039] like Figure 8 As shown, as another preferred embodiment of the present invention, the adapter 200 is integrated with a cylindrical design, one end is used to fix the guide 300, and the other end is fixed to the handle 100, and one end is used for the end of the card. The end has a protruding two ribs for fixing the adapter 200 to prevent rotation or offset, and the lower end of the two edges is convenient to remove the inner position. The bottom end has a groove for placing the magnet for fixing, adapter 200 upper end Using a taper design, it is convenient for the placement and location adjustment of the front-end guide.
[0040] The front end of the adapter 200 employs a six-roller slot, increasing the fixed stability, also increases the positioning function of the guide 300, and the internal six-roller groove fixing guide 300 prevents rotation, the upper end of the adapter 200 and the positioning groove are convenient to guide the connection. The put of 300.
[0041] On the other end of the adapter 200, the central air is designed, and the fixed magnet is placed in the center, and the protruding prism is used to secure the adapter 200 and the handle 100 on both sides, prevent the offset and rotation, and the bottom end of the prism It is more convenient to add.
[0042] like Figure 9 As shown, as a preferred embodiment of the present invention, the guide 300 is sequentially composed of a guide portion 301, a positioning portion 302, a curved portion 303, and a connecting portion 304; wherein the guide portion 301 is cylindrical, the guiding portion 301 fixed height For 5mm, the positioning portion 302 is used to determine the drilling depth of the drill needle; the bending portion 303 is provided with a chamfer structure, the chamfer can be a folded angle or a rounded structure, which provides comfort. The curved portion 303 is bent in two places.
[0043] The connecting portion 304 is provided with a hexagonal groove for connecting to the adapter 200, and is conveniently replaced with magnetic suction.
[0044] The second groove 305 is provided in the middle of the guide 300, configured to indicate the positioner positioning height, and a second groove 305 is an increase of one millimeter, freely selecting replacement.
[0045] The front end of the guide 300 is tensile for one millimeter for compensation height to determine the drilling depth of the drill needle, which can be freely selected. The second groove 305 is compensated for one millimeter, two grooves are compensated for two Mematic is pushed in this class.
[0046] The guide 300 is connected to the adapter 200, and the two-angle positioning enables the front end of the guide 300 to better and more finely, reaches the most suitable connection position, wherein the six-rib two-rib positioning arc .
[0047] like Figure 10 As shown, as another preferred embodiment of the present invention, the back portion of the guide 300 and the adapter 200 is used with a rounded transition from the front-end guide rod to make the transition more smoother.
[0048] The guide 300 is connected to the adapter 200 connection, which can better rotate the position at the position angle, with hexagonal linkage.
[0049] The working principle of the present invention is:
[0050] The present invention uses the separation design guide 300 detachable replacement, and the central portion is used to increase the degree of fixing stability, and the handle 100 is used to provide a better use touch, the rear expand design is provided. Good contact with the palm contact enhancement, the guide 300 and the handle 100 are connected to the handle 100, and the adapter 200 has a hexraw card slot to improve more stability, and the magnetic design is more convenient to put it. The corresponding dimension guide 300 is only replaced when the needle is drill. This guide takes up small space for easy placement and carry. The second groove 305 is used to display the guide guide positioning height, and the center cavity is used to place the magnet. The guide is used to increase the angle. In the front end, the air cylinder is added to increase the taper increase height, convenient to put it in Drill.
[0051] In the description of the present invention, it is to be understood that the terms "first", "second", etc. are used only for the purpose of describing, and cannot be understood as indicating or implies a relative importance or implicitting the number of techniques indicated. . Thus, in the description of the invention, the meaning of "multiple" is two or more unless otherwise stated.
