Preferably, the upper end and the lower end of the sleeve are both provided with threaded pipes; open grooves are formed in the threaded pipes.

Preferably, the open grooves are arranged in a plurality of equidistant surrounding mode by taking the center of the threaded pipe as an axis.

Preferably, a triangular support plate is arranged between the sleeve and the fixed seat.

Compared with the prior art, the beneficial effects of the utility model are that: the fixed seat and the adjusting seat are connected in a clamping and embedding manner, so that the overall stability is improved, and meanwhile, the positioning and locking functions are further realized through the shaft pin, and the processing stability and precision are ensured; the whole adaptability of the device is enhanced by designing a plurality of drill holes above the adjusting seat, and the adjustment can be carried out according to the requirements so as to ensure the adaptation of the drill bit and the drill holes and reduce the occurrence of the situations of deviation of the drill bit and easy damage of the drill bit; and finally, the connection and fixation mode between the sleeve and the bench drill supporting rod is improved, so that the bench drill supporting rod can be fixed more conveniently without other tools.

Drawings

Fig. 1 is a schematic perspective view of the present invention.

The drilling tool comprises a sleeve 1, a fixed seat 2, an adjusting seat 3, a drilling hole 4, a drilling sleeve 5, a groove 6, a jack 7, a shaft pin 8 and a threaded pipe 9.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, the following detailed description is provided in conjunction with the accompanying drawings: a bench drill bit righting device comprises a sleeve 1, a fixed seat 2 and an adjusting seat 3; the fixing seat 2 is fixed outside the sleeve 1, a triangular supporting plate is arranged between the sleeve 1 and the fixing seat 2 and used for playing a role of stabilizing the structure, and grooves 6 are symmetrically arranged on two sides of the inner end of the fixing seat 2; the adjusting seat 3 is clamped with the grooves on two sides of the inner end of the fixed seat 2 through the convex structures on two sides of the adjusting seat; adopt the connected mode of inlay card, firstly play the effect of fixed direction, secondly strengthened horizontal stability through the inlay card mode of protruding structure and recess.

A plurality of jacks 7 which are symmetrical at equal intervals are arranged at two sides of the fixed seat 2; one end of the adjusting seat 3 close to the fixed seat 2 is provided with a through hole; the insertion hole 7 is matched with the through hole in size and is connected with the through hole through a shaft pin 8. And a baffle ring is arranged outside one end of the shaft pin 8, and the other end of the shaft pin is of a threaded structure. The fixed seat 2 and the adjusting seat 3 are locked and fixed through the shaft pin 8, and the occurrence of instability factors caused by vibration in the use process is reduced.
