Description
Technical field
The utility model relates to hand tools technical field, particularly relates to a kind of file handle.
Background technology
The instrument often used when file is polishing finishing object, form a set of by the file of multiple section configuration and size, dissimilar file is selected according to the situation of processed object surface during use, the rear portion of file all can be furnished with handle, file handle has wood handle and reassembling type handle, wood handle easily skids and comes off in the course of work run up, and existing reassembling type handle also exists the shortcomings such as complex structure, cost is high, dismounting is inconvenient.Given this, be necessary to provide a kind of new file handle to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of file handle, and itself and file support the use, the file of fast changeable different model, and have clip firm, easy to carry, security is high, and structure is simple, the advantage that cost is low.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of file handle, be made up of handle body and the snap ring that screws being installed on handle body front end, handle body center is provided with file installing hole, it is characterized in that: described handle body front end is provided with the snap ring erection column installed and screw snap ring, described handle body front portion and snap ring erection column center are provided with a clearance groove, snap ring erection column is divided into upper and lower two parts by clearance groove, is provided with a semi-circular boss outside the head of wherein the first half snap ring erection column; Described screw that snap ring center is provided with can by the center hole of snap ring erection column, the outer end of center hole is provided with the eccentric circular hole that a diameter is greater than center hole diameter.
Further, the diameter of described eccentric circular hole is diameter and semi-circular boss maximum gauge sum, the base of described eccentric circular hole and the base coincident of center hole of snap ring erection column.
Further, the rear end of described snap ring erection column is provided with an annular balance chuck, described in screw snap ring rear end and be provided with the balance trepanning supporting with balancing chuck.
Compared with prior art, file handle described in the utility model, the two parts up and down utilizing clearance groove to be set to by snap ring erection column can to open point, and become eccentric elliptic at its arranged outside semi-circular boss, utilize the eccentric circular hole screwing snap ring to control the folding of snap ring erection column, only need rotate and screw snap ring half cycle and can complete the clamping of file fast or unclamp action, balance chuck can make to screw snap ring and rotate smooth-going.

Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 6, the utility model provides a kind of file handle, be made up of handle body 1 and the snap ring 2 that screws being installed on handle body front end, handle body center is provided with file installing hole 3, described handle body front end is provided with the snap ring erection column 4 installed and screw snap ring, anterior and the snap ring erection column center of described handle body is provided with a clearance groove 5, and snap ring erection column 4 is divided into upper and lower two parts by clearance groove 5, is provided with a semi-circular boss 6 outside the head of wherein the first half snap ring erection column; Described screw that snap ring 2 center is provided with can by the center hole 7 of snap ring erection column, the outer end of center hole is provided with the eccentric circular hole 8 that a diameter is greater than center hole diameter.The rear end of described snap ring erection column is provided with an annular balance chuck 9, described in screw snap ring 2 rear end and be provided with the balance trepanning 10 supporting with balancing chuck.The diameter of described eccentric circular hole 8 is diameter and semi-circular boss 6 maximum gauge sum, the base of described eccentric circular hole 8 and the base coincident of center hole 7 of snap ring erection column 4.
Based on the file handle of said structure design, handle body 1 and snap ring erection column 4 all adopt plastic production, plastics itself have certain stretching compression elasticity, snap ring erection column can make clearance groove narrow under the squeezing action of eccentric circular hole, make file that installing hole 3 is tightened up further, eccentric circular hole when not extruding snap ring erection column, then can make file that installing hole 3 is unclamped.In use, the most significant end of eccentric circular hole 8 is forwarded to semi-circular boss 6 side, now file and installing hole is in releasing orientation (as shown in Figure 5), then file is inserted in file installing hole 100, rotate and screw the least significant end extruding semi-circular boss 6 that snap ring 2 makes eccentric circular hole 8, further make file that installing hole is in gripping orientation (as shown in Figure 6).So repeatedly operate, on file handle, file can be changed fast.
The above; it is only most preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, all belong to the scope of claims protection.
