Description
Technical field
This utility model relates to a kind of quick chuck, specifically, relates to electric hammer quick chuck.
Background technology
At present, commercially available electric hammer more bit change when, need collet segment is used by, lift, lift the operation such as location, replacing construction is long, the most comparatively laborious, and needs to press down drill bit in position fixing process, and installation is inconvenient for.
Utility model content
It is reasonable that technical problem to be solved in the utility model is to provide a kind of compact conformation, installs and uses convenient electric hammer quick chuck.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
Electric hammer quick chuck, including collet body, four square sets and chuck, four square sets are formed convex structure by minor diameter part and large-diameter portion, the side of large-diameter portion is by the boss clamping inside steel ball and chuck, chuck is arranged with lower spring between part and the large-diameter portion above boss, the top of lower spring is provided with fixing pad, the side of minor diameter part is provided with spacing hole, spring it is arranged with between minor diameter part and chuck, the bottom of upper spring contacts with fixing pad, top is provided with steel ball seat, steel ball it is provided with between steel ball seat and spacing hole, collet body is set in the outside of minor diameter part and chuck, dust cap it is provided with between collet body and minor diameter part, dust cap and minor diameter part clamping.
Bottom the side correspondence chuck of described large-diameter portion and the fixing position padded is equipped with jump-ring slot, is provided with jump ring in jump-ring slot.
The length of described spacing hole is more than the diameter of steel ball.
Compared with prior art, the utility model has the advantages that: chuck structure advantages of simple of the present utility model, easy to assembly, by the cooperation of steel ball and spring, can realize directly, be quickly inserted and extract, the least, the daily replacing to drill bit of being more convenient for uses.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, dust cap, 2, collet body, 3, steel ball seat, 4, upper spring, 5, fixing pad, 6, lower spring, 7, chuck, 71, boss, 8, four square sets, 81, minor diameter part, 82, large-diameter portion, 83, spacing hole, 9, steel ball, 10, jump ring.
Detailed description of the invention:
nullAs shown in Figure 1，Electric hammer quick chuck，Including collet body 2、Four square sets 8 and chuck 7，Four square sets 8 are formed convex structure by minor diameter part 81 and large-diameter portion 82，The side of large-diameter portion 82 is by boss 71 clamping inside steel ball 9 and chuck 7，Chuck 7 is arranged with lower spring 6 between part and the large-diameter portion 82 above boss 71，The top of lower spring 6 is provided with fixing pad 5，The side of minor diameter part 81 is provided with spacing hole 83，Spring 4 it is arranged with between minor diameter part 81 and chuck 7，The bottom of upper spring 4 contacts with fixing pad 5、Top is provided with steel ball seat 3，Steel ball 9 it is provided with between steel ball seat 3 and spacing hole 83，Collet body 2 is set in the outside of minor diameter part 81 and chuck 7，Dust cap 1 it is provided with between collet body 2 and minor diameter part 81，Dust cap 1 and minor diameter part 81 clamping，Bottom the side correspondence chuck 7 of the large-diameter portion 82 and fixing position padding 5 is equipped with jump-ring slot，Jump ring 10 it is provided with in jump-ring slot.
In this utility model, the length of spacing hole 83 is more than the diameter of steel ball 9, so that steel ball 9 can freely up and down move；Meanwhile, in order to coordinate the motion of steel ball 9, inside steel ball seat 3, for the inner concave arc surface identical with steel ball 9 quantity.
When this utility model uses, drill bit directly inserting the endoporus of four square sets 8, steel ball and spring can firmly clamp drill bit；When needing to change, lower pressure collet body 2 just can easily take out, and greatly facilitates the routine use of electric hammer.
