The advantageous effect so set is：Using the above program, by the way of this fixed file, the instruments such as file There are many diameters, sets split type retaining sleeve, and file is threaded through in the perforation in split type retaining sleeve, and split type retaining sleeve is in cone Shape, can be movable in taper accommodating cavity, and under the impetus of adjusting rod, perforation gradually tapers up, so as to gradually clamp file, The file that can be adapted between difference, realizes the fixation to file, and further adjusting rod rotation gradually promotes split type clamping Set clamps, and this control mode is simple, it is easy to accomplish.

The utility model, which is further arranged to the split type retaining sleeve, includes at least 3 block gaps setting grip block, described Grip block includes leptoprosopy and compresses face for what modulated pole compressed, and the leptoprosopy, which is less than, compresses face setting, it is described compress face and It by the first joint face, the second joint face and houses the contact inclined-plane that cavity wall contacts between leptoprosopy with taper and connects, it is described The arc-shaped setting in inclined-plane is contacted, is set between the second joint face on the first joint face and adjacent grip block on the grip block useful In grip block being pressed on taper housing spring is compressed on cavity wall.

The advantageous effect so set is：Using the above program, split type retaining sleeve is formed after grip block closes up, that is, is closed Hold together rear tapered, while the conical centre opens up perforation, and adjacent grip block is connected by compressing spring, by the work for compressing spring With, after grip block to be formed to circular form, can outside spreading, house on cavity wall so that grip block is pressed on taper, Simultaneously after the thrust of adjusting rod disappears, under the action of spring is compressed so that split type retaining sleeve is flared out, so as to bore It is gradually resetted in shape storage tank so that perforation expansion, it is this simple and practical in structure, it is easily installed, effectively realizes to works such as files The clamping of tool.

The utility model is further arranged to be additionally provided with push jack between the adjusting rod and split type retaining sleeve.

The advantageous effect so set is：Using the above program, by setting push jack so that so that the effect of adjusting rod is more To be accurate, deviation is less prone to, it is single to act on a grip block so that with the spring that the grip block is connected due to for a long time It is deformed by more energetically, influences service life, while push jack is set so that stress is more uniformly distributed so as to split type retaining sleeve It promotes highly efficient.

The utility model is further arranged to further include connector, and through hole, the connector are provided on the connector It is threadedly coupled by through hole with adjusting rod, the connector and fixed part thread fitting.

The advantageous effect so set is：Using the above program, connector is set so that the collet is more easily installed, together When also easily replaced to there is damaged grip block and push jack.

The utility model is further arranged to described clamping piece one end and is connected with adjusting rod, and the other end is connecting portion, described It is provided with to be inserted into the flange of reciprocating saw on connecting portion, is provided on the connecting portion and realizes that clamping piece and reciprocating saw are fixed Mounting hole.

The advantageous effect so set is：Using the above program, this connecting portion is set, is allowed to and saw blade on reciprocating saw Connection structure is consistent, so as to fulfill the connection of the connector and reciprocating saw, keeps the uniformity of connection structure, need not change past The connection structure sawed again, suitability are strong.
