A collecting tool (10) for use with a refuse collection bag (29), including a frame (12) having a number of frame members (13) which are joined by connectors (17). A number of retainers (31) attach a refuse collection bag (29) to the frame (12). A handle (30) is detachably attachable to the frame (1
A collecting tool (10) for use with a refuse collection bag (29), including a frame (12) having a number of frame members (13) which are joined by connectors (17). A number of retainers (31) attach a refuse collection bag (29) to the frame (12). A handle (30) is detachably attachable to the frame (12), so that the frame (12) and the attached bag (29) can be manipulated to position the collecting tool (10) during refuse collection. A number of legs (28) are detachably attachable to the frame (12), the legs (28) acting to support the frame (12) and an attached refuse collection bag (29) in an upright position (52). One of the legs (28) may optionally serve as the handle (30) or may help support the frame in a free-standing position (58). Optionally, one of the retainers (17) is a snap ramp (34), including a flat ramp portion (36) which is reversible in direction so that the flat ramp portion (36) may serve as an inwardly disposed entrance ramp (54), or as an outwardly disposed entrance ramp (56).

A clamping chuck as defined in claim 3, wherein an angle of a corresponding one of said truncated cone surfaces is selected so that a movement of said ring element along said truncated cone surface of said end portion of said chuck body is a transmission axially. 5. A clamping chuck as defined in claim 3, wherein a respective one of said truncated cone surfaces has an angle substantially between 10° and 20°. 6. A clamping chuck as defined in claim 5, wherein said angle amounts to substantially 15°. 7. A clamping chuck as defined in claim 3, wherein said truncated cone surface of said ring element extends axially from said abutment surface of said ring element to an opposite axial end. 8. A clamping chuck as defined in claim 2, wherein said truncated cone surface of said end portion of said chuck body extends axially to said abutment surface of said chuck body. 9. A clamping chuck as defined in claim 3, wherein said ring element with said truncated cone surface of said ring element is seated on said truncated cone surface of said end portion of said chuck body. 10. A clamping chuck as defined in claim 1, wherein said ring element is formed as a ring which increases and reduces at least in a radial direction. 11. A clamping chuck as defined in claim 11, wherein said ring expands and narrows. 12. A clamping chuck as defined in claim 1, wherein said ring element is formed as a shrinkage ring. 13. A clamping chuck as defined in claim 1, wherein said ring is composed of a material with a higher thermal expansion coefficient than that of said longitudinal portion of said chuck body which is provided with said receptacle. 14. A clamping chuck as defined in claim 1, wherein said ring element is composed of aluminum. 15. A clamping chuck as defined in claim 1, wherein said ring element is composed of austenitic steel. 16. A clamping chuck as defined In claim 1, wherein at least said longitudinal portion of said chuck body which has said receptacle is composed of steel. 17. A clamping chuck as defined in claim 1, wherein said ring element is formed so that during cooling of a part of said longitudinal portion of said chuck body which is free from said ring element, said longitudinal portion of said chuck body is first shrunk with radial clamping of a tool shaft in said receptacle, and said ring element during shrinkage is movable along said truncated cone surface of said end portion of said chuck body axially forwardly with its abutment surface against said shoulder of said inserted tool. 18. A clamping chuck for clamping tools by shrinkage, comprising a chuck body having a longitudinal portion with a receptacle open at one end for insertion and receiving a tool to be clamped with a tool shaft, said chuck body at an open end of said receptacle having an end-side abutment surface for the insertable tool so that during insertion a rear-side shoulder of the tool axially abuts against said abutment surface; and a ring element arranged in a region of an end portion of said chuck body which carries said abutment surface, said ring element being axially supportable against said chuck body in one axial direction and being provided with an abutment surface, said abutment surface of said ring element being located forwardly at an end which is axially adjoining said abutment surface of said chuck body so as to be associated with the shoulder of the tool, for axial clamping of the inserted tool by means of said ring element with respect to said chuck body, wherein said ring element is formed so that during heating of said ring element it expands radially more than said longitudinal portion of said chuck body, and is movable along said truncated cone surface of said end portion of said chuck body axially rearwardly and with said abutment portion of said ring element away fro
