Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of the utility model embodiment；
Fig. 2 is 2 connecting rod structural schematic diagram of the utility model embodiment；
Fig. 3 is 2 outer bar structural schematic diagram of the utility model embodiment；
Fig. 4 is that the utility model embodiment 2 adjusts tube-in-tube structure schematic diagram.
Specific embodiment
Embodiment 1: as shown in Fig. 1, the utility model includes that connecting rod 2, setting are used for and magnetic force in 2 one end of connecting rod
2 other end of connecting rod is arranged in for installing the fixed link 4 of drill bit, being arranged in fixed link in brill or the connector 1 of power drill connection
The drill bit 5 of 4 outboard ends and being nested with is used for and the non-slip shaft that is in contact of threaded hole with decollation bolt in the outside of connecting rod 2
Hold 3.Anti skid bearing 3 uses deep groove ball bearing.Corresponding anti skid bearing is selected according to the threaded hole with decollation bolt when use,
The lateral wall of anti skid bearing is set to be in contact with threaded hole, so at work, it is ensured that connecting rod 2 is constantly in and threaded hole
It is not in bounce at concentric position, while guaranteeing that the hole drilled out is located at the center position of decollation bolt,
Connecting rod 2 can be effectively prevented and the screw thread collision of threaded hole causes screw thread to damage, effective protection screw thread.
Drill bit mounting hole is provided at the axle center of fixed link 4, drill bit 5 is mounted in drill bit mounting hole, in fixed link 4
The drill bit fixed pin 6 for being fixed on drill bit 5 in drill bit mounting hole is provided on side wall, in the lateral wall of drill bit fixed pin 6
It is provided with screw thread, by screwing or back-outing the fixation and replacement of realization drill bit 5, is easily installed the drill bit of various sizes.
Embodiment 2: the threaded hole in order to meet different disconnected hole depth and different inner diameters, in 1 other structures of embodiment
In the case where constant, only change the structure of connecting rod 2.
As shown in Fig. 2 to 4, the connecting rod 2 includes interior bar 201 and the outer bar 202, In being nested on the outside of interior bar 201
Through-hole 205 compatible with the bolt head shapes of dormant bolt 208 is provided on the side wall of outer bar 202, it is in outer bar 202 and logical
It is fixed with attaching nut 207 on the side wall of 205 opposite side of hole, several groups and through-hole 205 are provided on the side wall of interior bar 201
Position is corresponding and runs through the connecting hole 210 of interior bar 201, and dormant bolt 208 is after through-hole 205 and connecting hole 210 and even
The realization of connected nut 207 is spirally connected.Fluted 206 at the position of attaching nut 207, attaching nut 207 is mounted in groove 206,
So that attaching nut 207 will not protrude the lateral wall of outer bar 202.When the length for finding connecting rod 2 is inadequate, countersunk head can be screwed out
Bolt 208 adjusts the relative position of interior bar 201 and outer bar 202, and the connecting hole 210 and through-hole 205 when by suitable dimension are opposite
It answers, is then threaded into dormant bolt 208, interior bar 201 and outer bar 202 is fixed.
Since deep groove ball bearing is standard component, the screw thread pore size with dormant bolt is larger in order to prevent, and connecting rod
Outer diameter it is smaller, can not find the anti skid bearing of suitable dimension.It is socketed with adjusting sleeve cylinder 204 in the outside of outer bar 202, in outer bar
It is axially disposed on 202 lateral wall to have fixture block 203, it is provided on the inner sidewall of adjustment sleeve 204 and is adapted with fixture block 203
Card slot 209, the bottom of card slot 209 is provided with the baffle 211 for placing the abjection of fixture block 203, anti skid bearing socket
In the outside of adjustment sleeve 204.It can be equipped with the adjustment sleeve 204 of different-thickness, according to the actual situation, by the tune of suitable dimension
A whole set of cylinder 204 is nested in the outside of outer bar 202, under the action of fixture block 203 is with card slot 209 together with rotate.When in use, due to
It needs firmly to press down on drill bit 5, therefore baffle 211 is set in the bottom of card slot 209, sleeve will be adjusted using outer bar 202
204 pressings prevent outer bar 202 and adjustment sleeve 204 from axially opposing displacement occurs, prevent in the threaded hole for having bolt with section
Sleeve 204 is adjusted to disengage.
